[06:27] <ibanezmatt13_> Good Morning :)
[06:30] <ibanezmatt13_> fsphil, In your SSDV program, what does '-t' represent? I've currently got -t 50
[06:31] <fsphil> haha
[06:31] <fsphil> on decode, drop 50% of the packets at random :)
[06:32] <fsphil> won't have any effect on encoding so not gonna be an issue
[06:32] <fsphil> but remove it anyway
[06:32] <fsphil> why did you add it?
[06:32] <ibanezmatt13_> I've absolutely no idea ;P
[06:33] <ibanezmatt13_> I'll remove it, thanks
[06:33] <fsphil> morning btw :)
[06:33] <ibanezmatt13_> yeah good morning :)
[06:34] <ibanezmatt13_> By the way, I was talking to my Dad last night, and he doesn't think there's an issue with my power supply.
[06:35] <ibanezmatt13_> He doesn't think that the reason the NTX2 goes all over the place when the Pi Cam takes a picture is due to power issues
[06:35] <ibanezmatt13_> Even when I move the mouse on the Pi, the NTX2 fluctuates a little
[06:36] <fsphil> the frequency it transmits at is only affected by the supply voltage, the signal going into the TX line and temperature
[06:36] <ibanezmatt13_> It was sat on my window ledge all day yesterday, it got rather hot.
[06:36] <ibanezmatt13_> But I can't see it being exactly that
[06:37] <fsphil> temperautre effectstend to be slow
[06:37] <fsphil> typing on a laggy connection is no fun :)
[06:38] <ibanezmatt13_> hmm, I'm gonna test it out again today. I should really be able to receive all the packets of images at close range and I loose almost half of them sometimes
[06:43] <ibanezmatt13_> Is there not a chance that the Pi's processor cannot handle the use of so much at once?
[06:44] <ibanezmatt13_> Taking pictures, videos, reading GPS, sorting it out, packetising pictures, removing things from directories, searching for best files, sending packets, sending telemetry... etc
[06:44] <fsphil> I do this on a 7mhz avr
[06:44] <ibanezmatt13_> fair enough
[06:44] <ibanezmatt13_> So it can only really be temp, voltage, or signal on TX line. Hmm
[06:44] <fsphil> I suspect so
[06:45] <ibanezmatt13_> So one of those factors is loosing half of my packets during transmission
[06:45] <fsphil> if you're not transmitting anything, and hearing something other than a steady tone
[06:45] <fsphil> then there's noise coming from somewhere
[06:45] <ibanezmatt13_> when I'm not transmitting it's a steady tone with the odd small fluctuation

[06:46] <ibanezmatt13_> Later on, I'll record a few seconds of the NTX2 on steady tone for you. And I'll also record how it reacts to taking a picture on the Pi Cam

[06:49] <cuddykid> morning all
[06:51] <fsphil> morn
[06:52] <cuddykid> I can foresee a slight problem judging the neck lift - this acetylene hose weighs quite a bit. Any tips on how to get neck lift measurement as accurate as possible?
[06:56] <fsphil> other than weighing the hose, not much
[06:57] <fsphil> all my stuff has been smaller
[06:57] <cuddykid> yeah, what I did last time was mark the hose at a point then hold it at that point
[06:57] <cuddykid> and weigh from that point
[06:57] <cuddykid> not really the most accurate

[07:03] <Ian_2E0XOD> Good Morning all > TiTan One will be launched from WW2 Thorpe Camp Visitors Centre Lincolnshire UK at 12:00 hrs - Balloon weight 200g - Payload 100g - Lifting capacity 300g - Accent rate 5.4 mtr/s - Target 1 mtr/s - Flight duration via calculatot 89 min.
[07:04] <Ian_2E0XOD> Good Morning Dave - Jess has corrected the error from our last launch
[07:05] <daveake> Oh good. What was it? I've forgotten (so many launches these days!)
[07:06] <cuddykid> Ian_2E0XOD: what freq?
[07:06] <cuddykid> I'm on 434.3 at that time
[07:06] <daveake> And what does " Accent rate 5.4 mtr/s - Target 1 mtr/s" mean?
[07:06] <Ian_2E0XOD> Flight mode with GPS i BELIVE
[07:06] <daveake> Oh that
[07:06] <Ian_2E0XOD> YEP
[07:06] <daveake> Yeah not the first time that's happened!
[07:06] <cuddykid> Ian_2E0XOD: so no radio?
[07:06] <Ian_2E0XOD> I understand
[07:07] <Ian_2E0XOD> Yes all connected and working
[07:07] <cuddykid> Ian_2E0XOD: what frequency is the radio on?
[07:07] <Ian_2E0XOD> I belive 434 .202.00
[07:08] <cuddykid> ok - can you ensure it's no higher than that as I'm on 434.3
[07:08] <cuddykid> at that exact same time :P
[07:08] <Ian_2E0XOD> Ok I will check my txt and report
[07:08] <cuddykid> cheers
[07:10] <Ian_2E0XOD> Correct 434.202.00 - if no-one is using 434.200.00 then I can ask jess to re-configure the frequency is that ok
[07:10] <cuddykid> Ian_2E0XOD: cool - yes please, the lower the better :)
[07:11] <Ian_2E0XOD> Roger contacting Jess now
[07:11] <cuddykid> as mine is set to 434.3 I think it seems to reside on around 434.28
[07:11] <cuddykid> thanks!
[07:13] Hix (~Hix@78-86-159-23.zone2.bethere.co.uk) joined #highaltitude.
[07:16] <Upu> now to work out whats launching today...
[07:18] <Ian_2E0XOD> The Balloon Technical information states with the Payload being at it's maximum the accent rate is 325 mtr/min - conversion in mtrs/s = 5.4 mtr/s - However we are trying to attain a lifting rate of 1 mtr/s hope that helps as the Payload is lighter
[07:20] <Upu> where are you launching from cuddykid ?
[07:20] <cuddykid> Upu: near Ombersley Worcester :)
[07:21] <Upu> and you're still using the stub antenna WILL YOU THINK OF THE DBS !!
[07:21] <Upu> thanks
[07:21] <daveake> Ian_2E0XOD Things like "max ascent rate" and "fill size" stated by the manufacturer are completely meaningless for HAB
[07:21] <fsphil> those poor photons, just making heat
[07:22] <Ian_2E0XOD> The Balloon is clean we are not using the Hifloat today - lets see if there is a different result
[07:22] <daveake> What we need is the ascent rate and burst alt that you're aiming for
[07:22] <Ian_2E0XOD> Yeh I understand it is just a guide
[07:22] <daveake> Not even that
[07:23] <Ian_2E0XOD> Dave confirmation of frequency change to 434.200.00
[07:23] <Upu> so just Titan 1 and Habe today ?
[07:23] <daveake> And yes that Hifloat stuff is pointless if you're not trying to get it to float (i.e. stay airborne for a day or so)
[07:23] <Upu> or did I miss anyone
[07:24] <fsphil> a weekend without steve launching something?
[07:24] <daveake> no steve no dave
[07:24] <daveake> :p
[07:24] <cuddykid> Upu: yeah - stubby all the way! :D
[07:25] <cuddykid> daveake / Upu: any tips on judging the neck lift reasonably accurately with this acetylene hose?
[07:25] <cuddykid> also, any tips in general for H2 apart from being careful?! :P
[07:25] <cuddykid> should be quite a good flight as the cloud is clearing - landing near Wales
[07:25] <Upu> don't set fire to it
[07:26] <cuddykid> first time one of my flights has ever gone off in that direction
[07:26] <daveake> I've done fine with the acetylene hose so long as neck lift > filler weight :)
[07:26] <cuddykid> I'll try not too :)
[07:26] <Upu> don't vent the H2 out to clear the tubes
[07:26] <daveake> Otherwise it's a challenge :)
[07:26] <cuddykid> daveake: ah - but I've got about 5 m of this hose
[07:26] <cuddykid> probably weighs more than the 2.2kg neck lift I need
[07:26] <Upu> and go easy on the regulator it may clatter a little
[07:27] <cuddykid> is it - shut off regulator, shut off cylinder, reopen regulator then close again ?
[07:27] <daveake> What I do is weigh the hose/filler with most of the hose on the ground
[07:27] <daveake> Use luggage scales
[07:27] <daveake> Then mark the point that the hose leaves the ground
[07:27] <cuddykid> daveake: yeah, was planning something like that - making a mark on the hose
[07:27] <cuddykid> yep
[07:27] <daveake> That's your filler weight deduct from neck lift
[07:28] <daveake> Write the weight on the hose next to the mark :)
[07:28] <cuddykid> clever
[07:28] <cuddykid> anyone know if these 2000g are easily susceptible to floating?
[07:28] <cuddykid> don't recall many using them
[07:29] <Upu> not used much
[07:29] <fsphil> I don'd remember anyone using H2 with a 2000g?
[07:29] <Upu> they dont' seem to go as high as the 1600's
[07:29] <Upu> Mick used H2 with one once
[07:29] <Upu> its certainly in the top ten
[07:29] <Upu> are you going for alt ?
[07:29] <cuddykid> yeah, but not extreme alt as the payload is 1kg
[07:30] <Upu> oh ok
[07:30] <cuddykid> the chap wants it to go as high as possible :P
[07:30] <cuddykid> and no 1600g in stock
[07:31] <Upu> let me have a think cuddykid
[07:31] <Upu> going to see if I can find Micks flight
[07:31] <Upu> aim for 6m/s cuddykid
[07:32] <Upu> it will certainly get high and will certainly burst
[07:32] <Upu> I suspect that is a fair bit of gass
[07:32] <cuddykid> I was going for just over 5m/s
[07:32] <cuddykid> around about 4m3
[07:32] <Upu> I wouldn't want a 2000g balloon bouncing round the ground full of H2
[07:32] <Upu> you want it to burst
[07:33] <cuddykid> yeah
[07:33] <daveake> About 4.5m^3 at a guess
[07:33] <Ian_2E0XOD> This looks interesting - must go now Gut's wishing you all a successfull flight from the TiTan Ballon Group
[07:33] <Upu> its your flight but personally I would go faster
[07:33] <Upu> good luck Ian_2E0XOD
[07:33] <daveake> 2 for the balloon 1 for the payload 1.5 for the lift
[07:34] <Upu> ok

[07:39] <Upu> morning ibanezmatt13_
[07:39] <cuddykid> glad it's not windy not the ground
[07:39] <cuddykid> would have been a nightmare
[07:39] <cuddykid> anyway - bbl
[07:39] <fsphil> conditions are great
[07:39] <Upu> oh and wear some gloves
[07:39] <Upu> if you don't already
[07:39] <cuddykid> Upu: latex?
[07:40] <Upu> no neck lift
[07:40] <daveake> pong
[07:40] <cuddykid> huh?
[07:40] <ibanezmatt13_> Upu, when I am using my NTX2 it works great. However, when I take a picture using the Pi Cam, the NTX2 frequency goes all over the place
[07:40] <ibanezmatt13_> morning daveake
[07:40] <daveake> power
[07:40] <ibanezmatt13_> Are you sure
[07:40] <cuddykid> why do I need gloves Upu ?
[07:40] <daveake> yes
[07:40] <Upu> the neck lift of the balloon can put quite a bit of pressure on the cord
[07:40] <cuddykid> oh!
[07:40] <cuddykid> yes
[07:40] <ibanezmatt13_> I really can't work out why it should be power if it's being powered off the mains
[07:40] <Upu> and as a by product on your hands
[07:40] <fsphil> you could burn your hand
[07:40] <cuddykid> I see

[07:42] <ibanezmatt13_> I thought of doing that but daveake said to power it off the Pi's 5v line.
[07:42] <daveake> 2 things affect the frequency. Main one is the 3.3V line on the Pi. Second one is the Vcc to the NTX2
[07:42] <fsphil> and temperature :)

[07:51] <WillDuckworth> morning - cuddykid - you still on for today?
[07:52] <ibanezmatt13_> also, would anybody be so kind as to remove my southern hemisphere location off spacenear.us/tracker - it's a little embarrasing :)
[07:53] Action: fsphil takes a screenshot :)
[07:53] <ibanezmatt13_> haha :) sure
[07:54] <daveake> #1 - You're using "counter" for both the telemetry sentence ID and the image ID
[07:55] <ibanezmatt13_> yeah, I figured it didn't have to go up in a set sequence so I just went for it
[07:55] <daveake> Since the image ID is from 0 to 255 only, you're going to wrap pretty soon and start re-using an old image ID
[07:55] <ibanezmatt13_> oh right, didn't know that
[07:55] <daveake> So use a separate counter
[07:55] <ibanezmatt13_> Yeah, I can change that with a different counter
[07:56] <ibanezmatt13_> I just can't work out what's wrong with my convert() function
[07:56] <daveake> handy hint use better names like SentenceCounter and ImageCounter, or whatever
[07:56] <ibanezmatt13_> good idea
[07:56] <ibanezmatt13_> I'm also trying to work out the reason for my convert function returning a negative latitude value. Strange
[07:57] <daveake> #2 - You're still assuming the GPS routine will return a new position
[07:57] <daveake> It needs to loop till it gets one

[07:58] <ibanezmatt13_> I thought it looped until it got a lock

[07:58] <ibanezmatt13_> the if statement
[07:58] <daveake> if <> loop
[07:58] <ibanezmatt13_> when I work out how, it's not just gonna pass
[07:59] <daveake> It needs to loop until it gets a position or it gives up (times out)

[07:59] <daveake> Either that, or the calling code could do the looping
[07:59] <daveake> #3 I suspect that this line:
[07:59] <daveake> if orientation == "S" or "W":
[07:59] <daveake> isn't doing what you want
[08:00] <ibanezmatt13_> I thought that S and W were always negative values
[08:00] <daveake> not that I know Python but in other languages it would be...
[08:00] <fsphil> the or happens before the ==
[08:00] <daveake> if (orientation == "S") or (orientation == "W")
[08:00] <daveake> or
[08:01] <daveake> if orientation in ["W", "S"]

[08:01] <fsphil> aaah did not know that

[08:01] <ibanezmatt13_> I've never seen it in that form before. The "if orientation in ["W", "S"]
[08:02] <fsphil> it tests for a value in a [list]
[08:02] <daveake> Well whatever the Python way is, but your code I think isn't doing it
[08:02] <ibanezmatt13_> What if I did: if orientation == "S" or orientation == "W": That's a little similar to what you did above
[08:03] <daveake> In most languages orientation == "S" or "W" is really orientation == ("S" or "W") or perhaps (orientation == "S") or "W", neither if which test for either character

[08:38] <Ugi_> The Adafruit GPS I bought a few weeks ago for another project
[08:39] <Upu> hi Ugi
[08:39] <Ugi_> turns out to have the 40K firmware
[08:39] <Upu> hmm thats interesting
[08:39] <Ugi_> proto PIC I got that from
[08:39] <Ugi_> Maybe that means they are now shipping with new firmware
[08:40] <Upu> they've not said as much
[08:40] <Upu> and its in their interest to tell me as they asked me to update the Wiki to indicate they weren't compatible
[08:40] <Ugi_> Could be a fluke, but if so then lucky for me..
[08:40] <Upu> I doubt it was a fluke as there was only one in existence

[08:43] <Upu> which is dumb

[08:44] <Upu> ah ok yes back order
[08:45] <Upu> waiting on supplier for the GPS modules

[08:45] <Upu> no don't worry :)
[08:45] <Ugi_> just thought you might be interested in the adafruit thing
[08:45] <Upu> I am
[08:46] <Upu> would like to test one to see if it does stop at 40km
[08:46] <Ugi_> Why do you think they chose 40K if ublox goes to 50?
[08:47] <Upu> thats a good point
[08:47] <Upu> inventek choose 40km as well
[08:47] <Upu> ish
[08:47] <Upu> they've upped it to a little more now
[08:47] <Ugi_> Just thought that nobody could want more?
[08:47] <Upu> I think the theory was at the time latex balloons were topping out about 38-39km
[08:47] <Ugi_> what's the record now?
[08:47] <Upu> but we've had 45km out of an off the shelf 1600g Hwoyee

[08:48] <Upu> MONDO-10 - 44379m
[08:48] <Ugi_> is that with a 10g payload?
[08:48] <Upu> no it wasn't heavy

[09:50] <fsphil> ISH time
[09:50] <fsphil> a bit later than 12:15
[09:50] <ibanezmatt13_> Ok, thanks :)
[09:50] <fsphil> probably 13:00, guessing that's BST
[09:51] <ibanezmatt13_> It's a little closer than the one yesterday so I may have more of a chance
[09:52] <ibanezmatt13_> How do I know when it's above the horizon
[09:52] <fsphil> when you're inside the blue circle
[09:52] <fsphil> but this assumes your horizon is perfectly flat
[09:52] <ibanezmatt13_> I believe we're actually on relatively high ground.
[09:52] <ibanezmatt13_> The only thing in our way really is houses :p
[09:53] <fsphil> if you where to plot your own horizon on the map, you'd receive it when the two overlap
[09:53] <ibanezmatt13_> I'm not sure how to do that
[09:54] <fsphil> can't, it's a mental exercise :)
[09:55] <ibanezmatt13_> When it gets over 20km, surely the horizon makes little difference if I'm not that far away from it anyway?
[09:55] <fsphil> yep
[09:55] <fsphil> generally inside the green circle there should be no problem
[09:55] <ibanezmatt13_> so I should still pick it up. I really don't know why I can't pick anything up
[09:56] <fsphil> possibly something simple
[09:56] <ibanezmatt13_> I had the antenna out of the window upstairs
[09:56] <ibanezmatt13_> The receiver was set to USB 434.074MHz
[09:56] <ibanezmatt13_> I heard nothing
[09:56] <fsphil> you always need to tune around a bit
[09:57] <fsphil> tune slowly
[09:57] <fsphil> between 434.060 - 434.090
[09:57] <ibanezmatt13_> Yeah, I'm gonna set the receiver's step size to the minimum one, it was really hard to use yesterday as it was stepping by a massive step
[09:58] <g0hww_len> actually you can plot your horizon in something like Splat or Radiomobile, if you get the terrin elevation data

[10:05] <ibanezmatt13_> just the antenna going into my receiver
[10:05] <Phil_M0DNY> What receiver do you have?
[10:05] <ibanezmatt13_> Alinco DJX-10
[10:05] <ibanezmatt13_> I have it set very simply to the frequency, USB band, and I have now got a very small step size to tune around a bit
[10:06] <ibanezmatt13_> How close to the frequency do I have to be to pick it up? That may be why I didn't get anything
[10:06] <Phil_M0DNY> Yeah that should work, tune up and down a bit for it as the other phil says. Have you heard what 50 baud rtty sounds like?
[10:06] <ibanezmatt13_> yeah on Youtube
[10:07] <Phil_M0DNY> You have to be within 1khz or so to hear it.
[10:07] <ibanezmatt13_> hmm, in that case I should have definitely picked it up
[10:07] <Phil_M0DNY> It's pitch is tuning-dependent though, so it'll be rumbling if it's lower, and squeaky if it's higher.

[12:18] <g6gzh> pb0ner: 320 spacing is correct
[12:18] <ibanezmatt13_> rv on or off?
[12:18] <GMT> UXW: where are you ... IO91qe means nothing to me
[12:19] <mfa298> ibanezmatt13_: rv should normally be off.
[12:19] <pb0ner> oh something very week with proper shift is showing up
[12:19] <ibanezmatt13_> ok
[12:19] <Geoff-G8DHE> OFF normally
[12:19] <GMT> UXW: okay, just found you on map
[12:19] <Nerdsville> Titan is currently about 20 miles from me and not exactly booming in, using FCDP+ and a discone
[12:20] <G7UXW--Kevin> shift 310 here in Godalming
[12:20] <ibanezmatt13_> ok, I'm not far off green circle and getting nothing
[12:21] <Phil_M0DNY> ibanezmatt13_: It seems this is worse than normal, so wait until it's 20km or so before worrying.
[12:22] <ibanezmatt13_> I think it's only going up to 18km
[12:22] <PE2G> ibanezmatt13_: What antenna are you using?
[12:22] <Phil_M0DNY> Huh, well wait for the green line to pass you at least.
[12:22] <ibanezmatt13_> WSM-270 magmount
[12:22] <ibanezmatt13_> Phil_M0DNY, ok
[12:22] <G4MYS> just getting decodes it drift s
[12:22] <mfa298> or hope that HABE is a stronger signal (even if the antenna is supposed to be worse)
[12:22] <g0hww_len> i'm marginal. not quite enough signal, but fragments are getting through. drifting down a bit now, 434.199 on the low tone
[12:23] <g0hww_len> shift 300
[12:23] <ibanezmatt13_> I'm almost certain i can hear RTTY
[12:23] <ibanezmatt13_> It's sooooo faint over the white noise, but I'm sure
[12:24] <Phil_M0DNY> ibanezmatt13_: Plug it into dl-fldigi and look for parallel lines on the waterfall.
[12:24] <pb0ner> ibanezmatt13 Gitar player?
[12:25] <ibanezmatt13_> dl-fldigi shows little. And yes pb0ner

[12:25] <Phil_M0DNY> ibanezmatt13_: Give it a couple of minutes, then have another tune around.
[12:25] <ibanezmatt13_> ok :)
[12:25] <ibanezmatt13_> pb0ner, how you know I play guitar :) ?
[12:26] <Wouter-[pa3weg]> It´s hardly a challenge when your name start with ibanez :P
[12:26] <ibanezmatt13_> haha, course not :)
[12:27] <pb0ner> indeed...
[12:27] <Wouter-[pa3weg]> chances are kinda small your name is actually matt ibanez
[12:27] <pb0ner> although I know some girl called that way
[12:27] <Wouter-[pa3weg]> hopefully not a girl named matt then ;)
[12:27] <ibanezmatt13_> slightly yeah. I created that as a gmail name when I was 13

[12:28] <pb0ner> some stupid question, what are the buttons 'RL and RV doing?
[12:29] <Geoff-G8DHE> RV is reverse tone mark/space space/mark
[12:29] <G7UXW--Kevin> RV = Reverce
[12:29] <pb0ner> thx..

[12:30] <Geoff-G8DHE> Oh just astarting to appear
[12:31] <ibanezmatt13_> still absolutely nothing

[12:32] <G4MYS> 434.19738
[12:32] <G7UXW--Kevin> I think it may have a duff aerial
[12:32] <pb0ner> I'm at 197.4....
[12:33] <GMT> another green one here
[12:33] <G4MYS> Iam pretty sure hes gotr a duff aerial !
[12:33] <G7UXW--Kevin> all red here
[12:34] <ibanezmatt13_> pretty much in green circle - nout
[12:34] <GMT> just the one green - #705 - now back to reds again
[12:34] <pb0ner> Signal is indeed very week, I'm on a ICOM910H and Diomond X5000, no pre-amp (looking for sponsors....:-)
[12:34] <daveake> Yes, this isn't in the best direction from here, but by now it should be green green green
[12:35] <pb0ner> red but : $$TITAN-O^e993&Jv753 1
[12:35] <iain-g4sgx> Not one decode yet and I'm not in the green circle. Def a bit low on ERP this one
[12:35] <iain-g4sgx> Am uin the green circle sori!
[12:35] <daveake> They should have used .650 no chance of keying up any repeaters :p
[12:35] <ibanezmatt13_> I guess I should hear it very clearly over noise when I get it?

[12:36] <jdtanner> Afternoon all. If Titan swings north into the Peaks I'll save you a journey and go looking for it :)
[12:37] <g6gzh> at least HABE will be on a quieter frequency for me, will have to wait and see how its stubby antenna performs
[12:37] <iain-g4sgx> If can decode HABE and hes using a stubby when I cant decode Titan I shall be trully amazed
[12:38] <pb0ner> HABE seems inpossible to me, someone is listening to his TV with a headset or so, very close to that

[12:50] <cuddykid> anyone know how to use video + photo mode?
[12:50] <GMT> well done 'ESB
[12:50] <Upu_M0UPU> whats the distance on tnat EI4ESB ?
[12:50] <Upu_M0UPU> oh ignore me they are using silly location information so dl-flgigi can't calculate it
[12:51] <EI4ESB> not sure how to calculate, any data on map?
[12:52] <Upu_M0UPU> http://www.movable-type.co.uk/scripts/latlong.html
[12:52] <Upu_M0UPU> can do it
[12:52] <Geoff-G8DHE> 380Kms to Dublin
[12:52] <Upu_M0UPU> normally dl-fldigi tells you in the box at the top
[12:52] <g6gzh> 12:29 < g6gzh> is dl-fldigi not parsing the lat and long without a decimal point ?
[12:52] <g6gzh> glad it's not just me then
[12:53] <Upu_M0UPU> known bug
[12:53] <Upu_M0UPU> stuffs up the bearing/elevation/distance boxes
[12:53] <g6gzh> yes
[12:53] <G8KNN> Google Maps ruler can measure distances
[12:53] <Geoff-G8DHE> Use GE and you can throw a ruler at it
[12:54] <G8KNN> It would be nice to have the ruler enabled on spacenear.us
[12:54] <ibanezmatt13_> what's the shift on Titan atm?
[12:54] <Upu_M0UPU> 320
[12:54] <ibanezmatt13_> ok, and freq?
[12:54] <Upu_M0UPU> 434.196
[12:54] <Upu_M0UPU> 197
[12:54] <ibanezmatt13_> thanks
[12:55] <Geoff-G8DHE> 386Kms at the moment see http://360.g8dhe.net/hab_flights/TITAN_20130609/index.php?ind=2
[12:55] <Upu_M0UPU> good range
[12:56] <Geoff-G8DHE> Its into some turblence now
[12:56] <Upu_M0UPU> yep
[12:56] <g4fui> Low reported sigs BUT good ranges, seems a bit "odd" (I'm not allowed to say "anamalous") don't you think?
[12:56] <Upu_M0UPU> its down on power or antenna isn't great
[12:57] <ibanezmatt13_> I've never been in a green circle before :) Not that I'm getting anything like...
[12:57] <Upu_M0UPU> but this is what happens when your antenna is 15km high :)

[12:58] <g6gzh> Well I'm convinced my colinear has too much gain for high elevation as almost all the flights I've monitored have been weaker at altitude
[12:58] <EI4ESB> signal strength low, s/n =14 db, but still decoding
[12:58] <Geoff-G8DHE> -14 degrees centigrade!
[12:58] <LazyL_M0LEP> It's at least 10dB down on what I'd expect from a payload there at that range...
[12:59] <Upu_M0UPU> I suppose they are designed for borizontal
[12:59] <Upu_M0UPU> not horizontal.
[12:59] <Upu_M0UPU> yes LazyL_M0LEP sounds about correct
[13:00] <Jess--> seems a fairly steady ascent
[13:00] <Upu_M0UPU> was it intended to be this slow ?

[13:00] <Geoff-G8DHE> Lost its sense of direction now
[13:00] <Upu_M0UPU> no thats cuddykid
[13:00] <Jess--> it was intended to be a little faster
[13:00] <Jess--> antenna is 1/4 wire
[13:00] <Upu_M0UPU> you're going to have a long drive
[13:01] <Upu_M0UPU> either your RFM isn't putting out the right power or you have something up with the antenna
[13:01] <Geoff-G8DHE> Directly over the airfield ?
[13:01] <Upu_M0UPU> its not a major issues as we can decode it
[13:01] <cuddykid> back and troubleshooting gopros
[13:01] <Jess--> feels like it, phone won't connect to habhub to update titan-chase
[13:01] <Jess--> titan1 chase is 50yds in front of me
[13:01] <EI4ESB> What antenna on payload yesterday on ANU?
[13:02] <pb0ner> still no green data, decoding about 85% correct...
[13:02] <Upu_M0UPU> I doubt there is anything that takes off from there that can exceed 55 k feet
[13:03] <G4MYS> you will seems very difficult todecode it.... Andy
[13:03] <Jess--> at last... after 90 mins of trying vodafone has a decent enough signal to update habhub
[13:03] <EI4ESB> Green data here good checksum for 5mins
[13:03] <pb0ner> PE2G.... my location is correctly set, dl-fldigi 'forgot' my location

[13:26] <Upu_M0UPU> whats was your predicted altitude for burst Jess-- ?
[13:26] <G7UXW--Kevin> ok need to make bios read cd first then ??
[13:26] <Upu_M0UPU> its probably already set
[13:26] <Upu_M0UPU> just tyr it
[13:28] <Jess--> predicted between 18 & 20 so its going better than expected
[13:28] <M0CJM> Trying Google chrome
[13:28] <chrisstubbs> G7UXW--Kevin, if its a "livecd" and you burn it correctly it will
[13:29] <Nerdsville> I'm only 15-20miles from TITAN and getting some serious fading now, no successful decodes for a while, is this because I am too near?
[13:29] <jdtanner> Getting Titan now from the Peaks...my local setup is inadequate due to farm buildings nearby.

[13:29] <eroomde> being too near is very likely not a problem
[13:29] <M0CJM> Works in chrome OK, looks like its broken in IE10

[13:29] <mfa298> wow, IE10 really does a bad job of showing spacenear.us, No balloon info boxes, No balloons and it looks like the chase cars are at the start locations
[13:29] <eroomde> or IE10 is broken
[13:29] <Geoff-G8DHE> You could be in the Null directly under the aerial
[13:30] <cuddykid> good job this flight isn't going too far
[13:30] <g6gzh> Nerdsville: same here at similar distance
[13:31] <cuddykid> anyone know of go pros overheating?
[13:31] <M0CJM> Yee, finding th same i Ie10, chrome seems fine though
[13:31] <G4MYS> Id agree if it were a colinear, we could not hera GB3IW in the transmitter hall 40 ft below a 25 watt aerial but with these aerials flipping about all over the show? I suspect a dry joint or half dead Tx myself
[13:31] <cuddykid> was quite warm out there.. but still, shouldn't overheat
[13:31] <Geoff-G8DHE> Titan sigs gettiing weaker here as well and i'm not under the aerial!
[13:31] <pb0ner> still no joy in decoding
[13:31] <cuddykid> just trying to eliminate all causes
[13:31] <G4MYS> Ive given up and awaiting HABE!
[13:32] <Babs> cuddykid, is the gopro sticking out of the package or surrounded in polystyrene?
[13:32] <Nerdsville> signal is strong but is fading in a regular cycle, similar to tumbling satellite signals I've received
[13:32] <cuddykid> Babs: sticking out a little but surrounded by poly. A lot of free space inside box though
[13:32] <Geoff-G8DHE> There is still a lot of turblence look at the path its tracking
[13:32] <mfa298> I can finally see TITAN on the waterfall. but it is in a bad direction for me.
[13:32] <cuddykid> can't be more than 30C in there though
[13:32] <Babs> I did a bunch of testing for my payload last year and basically if I had polystyrene on any more than one side it overheated and shut down after about 15 mins
[13:32] <Babs> Do you have a photo?
[13:33] <cuddykid> ah actually - it doesn't make sense as they all seemed to shut down after about 2 mins
[13:33] <cuddykid> one after the other (order they were powered on in)
[13:33] <cuddykid> don't think that would happen twice out of co-incidence
[13:33] <cuddykid> just have to have fingers crossed that this firmware update has fixed it
[13:33] <Babs> its more the reflection of the heat into the gopro (whether from the side, the back or whatever). you can end up with a relatively cool payload inside the box, but a very hot gopro
[13:33] <g4fui> seems like some kind of timeout
[13:34] <cuddykid> just ran one now for 18mins.. didn't shutdown

[13:34] <Babs> do you have an external battery or just powering it off the internal one? Sometimes the external batteries shut down if you aren't drawing enough current from them (i.e. if you leave the gopro in idle mode)
[13:35] <cuddykid> just internal + bacpac
[13:35] <chrisg7ogx> Titan-One is a comparatively weaker signal here on the south coast
[13:36] <ibanezmatt13_> I've given up tracking Titan 1, absolutely nothing anywhere. I've gotta sort this thing out, it can't be like this when I launch mine

[13:37] <pb0ner> I'm off to the shower, brb
[13:37] <PE2G> Titan-One's signal becoming weaker, or is it me?
[13:37] <ibanezmatt13_> How can it get any weaker?
[13:37] <Babs> hmmm. just know then. defo not an external battery issue, the only thing i can think of is the polystyrene surroundings. i ended up mounting both of mine outside the payload
[13:38] <pb0ner> here it is getting stronger
[13:38] <Geoff-G8DHE> Yes its fading for me aerial might be bent ... ?
[13:38] <Babs> ps i did find that if it as shutting down because of heat, you would kno about it because it would become redhot
[13:38] <pb0ner> I'm decoding fairly well, miss out 1 or 2 characters in every packet
[13:39] <PE2G> I have fewer decodes now than at ~16k
[13:40] <ibanezmatt13_> So does an SDR improve the chance of picking something up?
[13:40] <eroomde> improve compared to what?
[13:40] <GMT> not 'improve', but sometimes easier to find the signal
[13:41] <mfa298> ibanezmatt13_: it can depend on how good it is as recieving compared to another radio
[13:41] <Geoff-G8DHE> Not really its just a very flexible and cheap hardware
[13:41] <Hes> or, very flexible and very expensive hardware, depending :)
[13:41] <GMT> SDRs 9eg RTL TV dongle) are not fantastically sensitive
[13:41] <ibanezmatt13_> I'm not sure whether my current setup will be good enough. I'v tried several different things now and not got anything at all on 4 HAB flights. There's gotta be something I can do
[13:42] <eroomde> what is your setup?
[13:42] <eroomde> and where are you geographically?
[13:42] <Geoff-G8DHE> I have a pair of RTL2832U/E4000 dongles and the perform fine, no pre-amp yet
[13:42] <ibanezmatt13_> I have a WSM-270 magmount antenna hanging out of my window going into an Alinco DJX-10. I am facing south east from Wigan near Manchester
[13:42] <mfa298> for tracking at home a different antenna might work better, a magmount on the window frame might not be the best.
[13:42] <ibanezmatt13_> any suggestions?
[13:43] <M0CJM> Getting some weak stuff here in Basingstoke from Titan-one
[13:43] <Geoff-G8DHE> Mount the aerial on a flat sheet of meatl at least a 1 foor square
[13:43] <Geoff-G8DHE> *foot
[13:43] <ibanezmatt13_> how about my car roof?
[13:43] <Geoff-G8DHE> Yes that's what is intended
[13:43] <chrisg7ogx> m0cjm same here in bognor
[13:43] <mfa298> car roof is good for a magmount
[13:44] <ibanezmatt13_> If I put it on the car, it's low down
[13:44] <Geoff-G8DHE> If the aerial isn't on a flat metal surface it won't perform
[13:44] <ibanezmatt13_> Ok, I'm gonna take a ride up to the famous billinge hill. Wont be long
[13:44] <PE2G> ibanezmatt13_: drive to a hill top somewhere
[13:45] <eroomde> ibanezmatt13_: try the hill
[13:45] <eroomde> and there are more sensisitive things than that alinco
[13:45] <ibanezmatt13_> will do now
[13:45] <mfa298> ibanezmatt13_: how do you get up the hill (car/bike/walk)
[13:45] <ibanezmatt13_> car
[13:45] <eroomde> but geography can make a big difference
[13:45] <mfa298> antenna on the car roof should be ideal then
[13:45] <M0CJM> Not getting any sensible decodes though
[13:45] <eroomde> yes antenna on a metal roof will also help

[13:57] <Geoff-G8DHE> dl-fldigi has locked on freq again but too weak to decode

[14:07] <LazyL_M0LEP> Ok, so what happened there? Signal's jumped by 10dB or so
[14:07] <eroomde> has it stopped fading in and out so much?
[14:07] <LazyL_M0LEP> maybe more.
[14:08] <Geoff-G8DHE> It was spinning much faster at one point, but the signal average smoothly varies but rapidly at times
[14:08] <g4fui> G4MYS - that's where my missing packet went!
[14:08] <LazyL_M0LEP> Possibly slightly, but it's definitely noticeably stronger.

[14:26] <ibanezmatt13> Can someone just confirm that what I have done is good enough for tracking: WSM-270 mounted on top of car roof - on top of pretty high hill - going straight into Alinco DJX-10 - set up on USB 434. whatever Mhz. Then from headphone jack in receiver to mic in laptop.
[14:26] <Geoff-G8DHE_> Sounds OK
[14:26] <pb0ner> seem fine ibanez
[14:26] <ibanezmatt13> I'm really confused
[14:27] <g4fui> Ibanez - does that radio have any inline attenuation?
[14:27] <LeoBodnar> pb0ner, Must be 3rd harmonic of 114.(3)Mhz
[14:27] <pb0ner> steep learning curve, keep playing around
[14:27] <ibanezmatt13> Maybe I'm dialing the wrong freq. I don't know what that means :\
[14:28] <pb0ner> yeah righ, and airplanes are txing wfm music.... not allowed
[14:28] <g6gzh> AFC can't track that drift!
[14:28] <g4fui> Never mind - it's a facility to reduce overload if you suffer from large signals nearby
[14:28] <ibanezmatt13> my dad says its got attenuation
[14:28] <G8KNN> I wonder why it suddenly shifted to quickly?
[14:28] <g4fui> If you have one and it's inline when you don't want it your radio will be v.deaf
[14:28] <ibanezmatt13> I'm not sure what you mean
[14:29] <pb0ner> problem is, due to doppler etc, signal is around the given frequence

[14:30] <Nerdsville> wow I'd left it going while I went and did something else, and it had completey drifted off the scale, retuned and then 1 minute later it had drifted off again.. ;-)

[14:32] <ibanezmatt13> is the Alinco good enough for a receiver?

[14:32] <g4fui> Review on EHam I just read says it's good, so it _should_ work for you
[14:33] <iain-g4sgx> CAn a local amateur tx on the frequency to ensure his RX is correct maybe?
[14:33] <daveake> If it has an attenuator built-in, that needs to be disabled

[14:34] <ibanezmatt13> ok
[14:34] <pb0ner> ok, that means your volume settings are fine

[14:34] <ibanezmatt13> I can receive my own payload perfectly
[14:35] <ibanezmatt13> Just nobody elses
[14:35] <daveake> Yes, but that's a very very strong signal compared to a balloon 10km+ away
[14:35] <ibanezmatt13> So for that I need to increase the volume a bit? What about receive filter bandwidth? Things like that may not be set right

[14:36] <pb0ner> with these week signals, you might pup that up a little. On the lower left just right of the "WF" button, it says something like -40 and the next one 90.... what are your setting there
[14:36] <ibanezmatt13> the receiver is deaf?
[14:37] <pws> Gain on my Alinco djx11: "Func" + "2". Should be "1"
[14:37] <daveake> Pardon?
[14:37] <pb0ner> (yeah, not receiving very well, e.g. not receiving weak signals)
[14:38] <ibanezmatt13> How about vfo? It's set to that

[14:38] <cuddykid> heading down to launch site to give it all another go
[14:38] <mfa298> vfo should be correct, that's the normal tuning mode, rather than memory mode
[14:38] <daveake> The fact that you can decode your own signals means that essentially everything is set up OK; the issue is that your local transmitter is a zillion times stronger than a real life HAB up in the sky

[14:40] <G4MYS> they are only a few quid on eBAY
[14:41] <ibanezmatt13> I will definitely get one.
[14:41] <mfa298> looking at the manual you might need to enable expert mode before you can turn the attenuator on/off
[14:41] <jdtanner> Unfortunately, no 3G here so no uploads :/
[14:41] <ibanezmatt13> attenuator is definitely off, I'm sure.
[14:42] <G4MYS> Beware TV preamps are feed with 12V up the coax not on red & black wires, so you will need the power supply to they are about 12 quid
[14:42] <mfa298> have you enabled expert mode on the radio (I'm just thinking in basic mode it might not show you the state of the attenuator or other things)
[14:42] <ibanezmatt13> I've never put it in expert mode
[14:42] <ibanezmatt13> I'll go and get it
[14:43] <iain-g4sgx> Where are you ibanezmatt13? Maybe theres a 70cms repeater local to check

[14:43] <ibanezmatt13> I've tried all repeaters, can't get those either
[14:44] <ibanezmatt13> You can enable/disable attenuator in normal mode
[14:44] <iain-g4sgx> They may not be very busy tho! lol
[14:44] <iain-g4sgx> but they will send morse ident ebry few mins
[14:44] <ibanezmatt13> I tried several repeaters and left them on for 15 mins each, never got anything at all
[14:45] <g4fui> Mmm that's a bit worrying ...
[14:45] <G4MYS> do you have CTCSS decode switched on?
[14:45] <daveake> I wonder if the aerial connection is broken inside. That happens on the AOR AR8000
[14:45] <ibanezmatt13> don't know what CTCSS is
[14:45] <g4fui> I don't think they send CTCSS when IDing

[14:46] <ibanezmatt13> The antenna definitely works, it works for my payload fine
[14:46] <G4MYS> it happens a lot on hand helds I had a job where much if time was spent repairing hands helds used on hire just fixing aerial sockets!
[14:46] <iain-g4sgx> Wont need an antenna for a locakl paylopad!
[14:46] <ibanezmatt13> I know, but at least it works :)
[14:46] <daveake> ibanezmatt13> The antenna definitely works, it works for my payload fine
[14:46] <daveake> No ... you don't need an antenna for local decoding
[14:47] <pb0ner> well do not compare local signals with a 10mW balloon spinning around like hell....
[14:47] <ibanezmatt13> but if I take the antenna out, I don't get anthing
[14:47] <G4MYS> it needs to be put on a radio test set it should break squelch on FM at -119dbm any thing like -60 or - 80 and you have a fault
[14:47] <G7UXW--Kevin> have you tried using a local reaperet in fm ??
[14:47] <pb0ner> wow, that does not seem right
[14:48] <ibanezmatt13> I really need an expert to come down and help me :( I think GW8RAK said he'd pop down on Thursday
[14:48] <pb0ner> sound to me like some broken antenna socket, playing 'ATT'
[14:48] <mfa298> you could also test the antenna by finding a not so local FM broadcast station and try recieving with no antenna, the rubber duck, and the magmount and sww how the three variations work
[14:49] <g4fui> You should be able to pick up some stuff from Winter Hill

[14:52] <G4MYS> Is HABE to fly I wonder?
[14:52] <g4fui> It could be something simple like a splayed out inner receptacle on the BNC female connector
[14:52] <ibanezmatt13> perhaps
[14:52] <Geoff-G8DHE> Looks like HABE is on the launch site from its new position
[14:52] <G4MYS> or even better a BNC without a pin! seen that too! works real fine NOT
[14:52] <ibanezmatt13> May need to try an SDR
[14:53] <ibanezmatt13> Just got to do an errand, won't be long
[14:53] <pb0ner> yeah... you can break the by using a 50 Ohm and 75 Ohm together
[14:53] <eroomde> lots of lab manuals recommend cleaning our rf connectors with a bit of IPA on an earbud before using them
[14:53] <eroomde> amazing how you can get little whiskers across
[14:53] <g4fui> Or putting an N male into a BNC female ...
[14:53] <G4MYS> yes that all works!
[14:54] <pb0ner> N and BNC are the same...
[14:54] <G4MYS> No but they will mate suggest not to much power !

[14:54] <pb0ner> I use the together all the time, but be aware of the fact that BNC for video is 75Ohm and the pin is thicker..
[14:55] <ibanezmatt13> So is it more likely to be a broken receiver or a broken antenna?
[14:55] <eroomde> also note that BNCs are rated p to about 4GHz, N's quite a bit higher
[14:55] <G4MYS> they are related.. N was the Naval plug BNC was/ is British Naval connector N plug will slot into / onto BNC socket not a good idea but will go!
[14:56] <Geoff-G8DHE> Can't say but sockets get more wear
[14:56] <mfa298> ibanezmatt13: that's why I suggested trying the three options (no antenna, rubber duck and the magmount)
[14:56] <cuddykid> UP
[14:56] <Geoff-G8DHE> so check sockets first
[14:56] <G4MYS> very very true

[15:02] <pb0ner> we started to use different color coax for Video, Baseband, baseband-audio/Nicam
[15:03] <G4MYS> the 50R is more common as its used on transmission and as youve seen its also used on video signals as 75R

[15:03] <mfa298> ibanezmatt13: should be USB for the balloons
[15:03] <G4MYS> not nice as 75R would be a 2:1 VSWR at 50 R system!
[15:03] <Geoff-G8DHE> By convention we always use USB above 10MHz and LSB below 10MHz
[15:04] <chrisg7ogx> nothing here...yet
[15:04] <mfa298> you'de hear it with LSB but that's when you'de need the RV button on dl-fldigi
[15:04] <g4fui> Yes for any lenght of transmission line, but a single connector probably won't make that much difference 9?)

[15:04] <ibanezmatt13> mfa298: ok. I checked the two antennas. With no antenna at all, nothing, with both antennas, picked a radio station up fine
[15:04] <mfa298> that suggests the connector is good then.

[15:07] <G8KNN> nothing here in Cambridge
[15:07] <daveake> nothing here
[15:07] <pb0ner> well the problem is the thickness of the hole/centerpin, those differ

[15:07] <ibanezmatt13> what's the min/max the freq will move to
[15:07] <mfa298> No sign of HABE yet in the waterfall here (and it's in the right direction)

[15:08] <chrisg7ogx> nothing in bognor
[15:08] <eroomde> yes, but that won;t make much difference at low freqs
[15:08] <LeoBodnar> Socket for central pin that is
[15:08] <pb0ner> 434.300 +/- 2.5 is right most of the times
[15:08] <M0CJM> Sorry for the silence from Basingstoke, had family drop in on me! I presume HABE has launched?

[15:08] <G4MYS> yes,- but how well is his rx calibrated?
[15:08] <eroomde> the difference between the two in terms of series inductance or parallel capacitance will have a minscule effect on these kinds of freqs

[15:18] <eroomde> normal
[15:18] <G4MYS> just found a 75Ohm 90* plug on the shack! sure I can hear very weak RTTY on 300
[15:18] <Upu_M0UPU> well

[15:20] <pb0ner> you see... people are storing there 75Ohms BNC 'ON' the shack, not 'In' :-)
[15:21] <G4MYS> what Hz is it
[15:21] <G4MYS> What Hz is it? please
[15:21] <pb0ner> .298 ?
[15:22] <Rob_M0DTS_> between two tones on .298 is 1500Hz
[15:22] <G4MYS> I mean the shift sorry! and about the typo its in the shack not on the roof! HI
[15:22] <pb0ner> 1500 between?
[15:22] <pb0ner> should be 425
[15:22] <G4MYS> mny tnx
[15:22] <Upu_M0UPU> you got a preamp on the mast there Rob_M0DTS ?
[15:22] <Rob_M0DTS_> of course
[15:22] <LazyL_M0LEP> Ah. I guess that 25 element yagi's making a bit of a difference... ;)
[15:23] <Geoff-G8DHE> Concelman it is then daveake !
[15:23] <Upu_M0UPU> well 19 elements isn't cutting it :)
[15:23] <pb0ner> autoconfigure puts it on 425... are you using dl-fldigi or fldigi?
[15:23] <G8KNN> actual shift is 450
[15:23] <G4MYS> that will help !
[15:23] <daveake> Geoff-G8DHE I win :-)
[15:23] <Geoff-G8DHE> 2 HAB points
[15:24] <daveake> Only because I wondered wtf BNC stodd for when I was preparing for my exam
[15:24] <Rob_M0DTS_> HABE is very weak tho, fauly antenna?
[15:24] <Rob_M0DTS_> faulty
[15:24] <pb0ner> I'm prepping for a a set of M2 aerials on a AZ/EL rotor (mainly for SAT work
[15:25] <Geoff-G8DHE> Its been dipped in rubber and the signals are boncing about inside never to get out
[15:25] <G4MYS> I do hope I was not prophet of dome with the stubby! sorry
[15:25] <Rob_M0DTS_> aha
[15:25] <iain-g4sgx> BNC, summut to do with Naval connectior i think
[15:25] <G4MYS> possably!
[15:25] <Rob_M0DTS_> maybe it's radiationg more horizontally(my yagi is H polarity today...)
[15:26] <iain-g4sgx> cos its more waterproof than a pl259
[15:26] <pb0ner> yeah : British Naval Connector (and not waterproof) :-)
[15:26] <pb0ner> just kidding
[15:26] <pb0ner> pl259 sucks

[15:33] <g4fui> That's what 25el can do for you though!
[15:34] <G4MYS> thats cheating
[15:34] <pb0ner> not really cheating.... just better tools.
[15:35] <Rob_M0DTS_> i have 4off these 25el for EME but only had two up at once so far, to contact the stations running 70cm from the big dish in Aricebo a few years back.

[16:15] <jdtanner> Any chance of anyone getting to the top of the Malvern Hills to decode? ;)
[16:15] <Phil_M0DNY> PB0NER_Martijn: A GSM based tracker of some kind.
[16:16] <Jess--> the rfm22b is a bare transmitter, you have to tell it what to transmit
[16:16] <PB0NER_Martijn> Ok... seems logical
[16:16] <Jess--> that will be the one transmitting on 434, titan one was also using one

[16:17] <PB0NER_Martijn> I somehow can not figure out how to 'reply'
[16:17] <PB0NER_Martijn> 3g coverage is much, much better here (NL is absolutely flat)
[16:19] <ibanezmatt13> what's the target alt today?
[16:20] <mfa298> this one was aiming fairly high (37km I think)
[16:20] <ibanezmatt13> wow
[16:21] <Upu_M0UPU> but we may never know what altitude it reaches as the telemetry is broken
[16:21] <g4fui> I think what I can just see is the idle tone between sentences
[16:22] <ibanezmatt13> it may be an idea for tracker to keep writing to a log file with the time and altitude
[16:23] <G8KNN> and then get a pigeon to fly back with the sd card
[16:23] <PB0NER_Martijn> you need a computer for that....
[16:23] <M0CJM_Neil> I must admit, although things not going 100% to plan its a great way to spend a sunny Sunday afternoon in the shack in te garden with the doors wide open and a beer in hand :-)
[16:23] <ibanezmatt13> I'm using an RPI for mine. It may be an idea so if I recover it, I can look how high it got to even if decodes aren't great
[16:23] <g4fui> I'm just going to have to cut that lawn, there's a GP coming up !

[17:35] <Lunar_Lander> hello
[17:35] <Randomskk> you can't do that. it's valid syntax but it will always be true
[17:35] <Randomskk> same as if (thing == "a") or ("b")
[17:35] <Randomskk> and ("b") is always True
[17:35] <ibanezmatt13> yeah I fixed that this morning :) thanks
[17:35] <Randomskk> what did you replace it with?
[17:36] <ibanezmatt13> if (thing == "a") or (thing == "b"):
[17:36] <Randomskk> neater:
[17:36] <Randomskk> if thing in ("a", "b")
[17:36] <ibanezmatt13> that was another option mentioned :)
[17:36] <ibanezmatt13> Is it possible for a signal to be too strong by the way?
[17:36] <Randomskk> yesssss
[17:36] <Randomskk> but probably not your problem
[17:36] <ibanezmatt13> The signal off my payload is distorting
[17:37] <PB0NER_Martijn> interesting variable name .... thing
[17:37] <mfa298> I had a feeling that if statment wasn't going to work last night.
[17:37] <ibanezmatt13> I didn't use thing in the real... thing :)
[17:37] <ibanezmatt13> ah well, works now :)
[17:37] <ibanezmatt13> Wow this signal very strong. I've never heard it distort on vol 2
[17:38] <ibanezmatt13> it's ok actually
[17:38] <PB0NER_Martijn> and that is the most impotent... be aware of RF signal on your data lines.... shield for that
[17:38] <mfa298> for the ntx2 to pi with seperate power supply you probably want ntx2 gnd to pi gnd rather than battery gnd to pi gnd.
[17:39] <ibanezmatt13> It's currently connected to both...
[17:39] <ibanezmatt13> Pi ground is paralleled with Battery ground
[17:39] <PB0NER_Martijn> that is good
[17:40] <mfa298> if you've got a switching psu the input and output grounds may not be the same (and I think on some they say you shouldn't connect the two grounds together)
[17:40] <PB0NER_Martijn> gnd should be a 'star' not 'string'

[17:40] <mfa298> by that I mean the input and output grounds on the switching regulator
[17:41] <ibanezmatt13> oh right I see
[17:41] <PB0NER_Martijn> use the gnd of you actual power supply... where the positive comes from
[17:41] Nick change: LazyL_M0LEP -> LazyLeopard
[17:42] <PB0NER_Martijn> after being transformed that is
[17:42] <mfa298> as the signaling for the ntx2 is relative to the ground on the ntx2 it's the ground on the ntx2 that needs to be connected to the pi

[17:43] <ibanezmatt13> mfa298: so NTX2 ground goes to Pi Ground, where does the ground go from the regulator I have?
[17:43] <PB0NER_Martijn> input or output?
[17:44] <ibanezmatt13> output
[17:44] <PB0NER_Martijn> battery +/- go to input regulator, output regulator - to Pi, + to nxt2, and Pi

[17:45] <PB0NER_Martijn> oops
[17:46] <ibanezmatt13> is there a problem?
[17:46] <PB0NER_Martijn> run everything of the bat/regulator

[17:47] <mfa298> you can power through the header as well. Although you might need something better than a pp3 battery

[17:48] <M0CJM_Neil> Right guys & girls,m its been a fab afternoon and hope we can all do this again soon, thanks for all your help and support and will try and be here for Friday afternoons launch. Have a good week!
[17:48] <PB0NER_Martijn> yes, behind the microusb/fuse the whole 5v is just one bus
[17:48] <mfa298> I was going to try and do something similar
[17:49] <PB0NER_Martijn> I power my pi's via the USB port
[17:49] <mfa298> M0CJM_Neil: if you're around I think there's also a launch tomorrow/tuesday
[17:49] <M0CJM_Neil> What time fa?
[17:49] <M0CJM_Neil> mfa?
[17:49] <ibanezmatt13> I don't think a PP3 is up to powering the Pi, the GPS, the NTX2 and everything esle

[17:51] <mfa298> from the previous announcments it's probably 0900-1300 launch
[17:51] <M0CJM_Neil> umm sadly work 8 till 5
[17:51] <PB0NER_Martijn> right, that would not do....
[17:51] <ibanezmatt13> Is there anything wrong with powering the Pi off the mains, the GPS off the Pi, and just the NTX2 off a regulated PP3 - just for testing purposes?
[17:52] <Ugi_> Geoff-G8DHE - how did you generate that panorama? Would love to do one of those if I ever get a balloon up.

[19:40] marcosscriven (~marcosscr@cpc14-slam6-2-0-cust507.2-4.cable.virginmedia.com) joined #highaltitude.
[19:40] <Jess--> that doesn't look like a fun recovery
[19:40] <mfa298> I dont think we've heard yet, but mobile signals might make it hard for them to get online
[19:40] <ibanezmatt13> yeah, hope they find it
[19:41] <ibanezmatt13> I was talking to my Dad before about whether one NTX2 is good enough for sending both SSDV packets and telemetry.
[19:41] <Jess--> we got lucky with titan, managed to get a clear signal close in which located it exactly
[19:41] <mfa298> based on the "chase car" being so close I'd guess they've located it
[19:41] <mfa298> question will be how accessible it is
[19:41] <Wouter-[pa3weg]> one NTX will do, but it highly depends on your baud rate and imaghe resolution
[19:41] <mfa298> or can be (find someone with a chainsaw)
[19:42] <Wouter-[pa3weg]> what are you thinking about?
[19:42] <ibanezmatt13> Wouter-[pa3weg]: I'm sending telemetry between each packet so that's not a problem
[19:42] <Wouter-[pa3weg]> carrying two NTXes also gives you some redundancy
[19:42] <Wouter-[pa3weg]> but more mass & power consumption
[19:42] <ibanezmatt13> I said it would be ok, but he said it may not be. Then I said that so long as we use good code with lots of error checking, we could do with the lower weight
[19:43] <ibanezmatt13> And power yes
[19:43] <mfa298> however with the Pi there's not really a good way of running two ntx2s well
[19:43] <Wouter-[pa3weg]> so it really depends on what you try to achieve
[19:43] <Wouter-[pa3weg]> Oh, that I do not know
[19:43] <Wouter-[pa3weg]> as in interrupt handling in real time etc?
[19:43] <ibanezmatt13> Oh! I have a really important question.
[19:44] <mfa298> Wouter-[pa3weg]: the problem with the pi is to get good timing for the rtty you have to use the onboard uart
[19:44] <mfa298> and there's only one of those.
[19:44] <Wouter-[pa3weg]> yup, understood, that´s interrupt handling
[19:44] <ibanezmatt13> I'm using a Pi Cam and I'm hoping to take HD video. I also need to take low res pictures to transmit over NTX2. However, everytime I start the Cam taking a pic or vid, the NTX2 frequency goes all over the place and the serial basically waits until its finished.
[19:45] <ibanezmatt13> My Dad said something about interupts
[19:45] <mfa298> If you want redundancy in case your pi payload fails the best option might be to see if someone else has a payload to fly with it.
[19:45] <fsphil_> you can, with some hacking, use audio out to drive two
[19:45] <fsphil_> but in my quick tests it seemed unreliable, it locked up a few times
[19:45] <fsphil_> that's a power problem
[19:45] <ibanezmatt13> mfa298: even with the new power supply
[19:45] <ibanezmatt13> fsphil ^^
[19:45] <fsphil_> yep, but nothing at all can cause the uart to output anything other than 0v or 3.3v, other than power issues
[19:45] <Wouter-[pa3weg]> yes, you can indeed do stereo baseband on the sound card
[19:46] <mfa298> ibanezmatt13: my guess is the 3.3v line might be dropping voltage - it could be worth trying your code but remove the gps (and the code that talks to it)
[19:46] <fsphil_> something on the board just isn't handling the current drain well
[19:46] <fsphil_> so the voltage will drop a bit
[19:47] <Wouter-[pa3weg]> or do a dedicated I/O buffer, stabalizing with a separate ultra low power LDO
[19:47] <mfa298> I wonder if picam + ublox is pulling too much power from the 3v3 line
[19:47] <ibanezmatt13> perhaps I should power Ublox on batteries like NTX2?
[19:47] <fsphil_> I've had the ublox cause this on some breadboard circuits
[19:47] <Wouter-[pa3weg]> by the way, there is some modifications on the web to make the Pi run with other regulators for the 3v3
[19:47] <Jess--> if anyone fancies a laugh.... I have just found the reason for the weak signals from titan-one, the rfm22 was set to 1mW rather than 10mW
[19:47] <Wouter-[pa3weg]> the Pi one sucks a bit
[19:48] <mfa298> ibanezmatt13: but remember I your ublox probably wants 3v3 not 5v (like the ntx2)
[19:48] <fsphil_> Jess--, d'oh!
[19:48] <Jess--> missed it
[19:48] <ibanezmatt13> in that case, I'd have to get another regulator = more weight
[19:48] marcosscriven (~marcosscr@cpc14-slam6-2-0-cust507.2-4.cable.virginmedia.com) left irc: Ping timeout: 264 seconds
[19:48] <fsphil_> regulators are not heavy
[19:49] <Wouter-[pa3weg]> tiny SOT-23 regulators do not take much weight
[19:49] <Wouter-[pa3weg]> and for the low power parts, they are still good
[19:49] <ibanezmatt13> so I could get another regulator and regulate it down to 3.3v for the GPS
[19:49] <Wouter-[pa3weg]> depending off course on soldering skill...
[19:49] <mfa298> ibanezmatt13: if you can adjust the voltage on your regulator you could try putting the ntx2 back on the pi 5v line and run the gps from a seperate 3v3 line
[19:50] <ibanezmatt13> The Pi really does have issues with its 3.3v line doesn't it. I could try that actually :)
[19:50] <x-f> hah, a few still managed to receive titan even with 1mW!
[19:50] <x-f> including F5APQ :|
[19:50] <Wouter-[pa3weg]> too bad i was not in delft today
[19:50] <Wouter-[pa3weg]> 1mW would have been no problem
[19:50] <mfa298> if you look at the "data sheet" (aka wiki page) I think it says you can't pull much power from the 3v3 pine
[19:50] <mfa298> s/pine/pin/
[19:50] <fsphil_> yea I'd go with an external 3.3v
[19:50] <fsphil_> F5APQ is awesome

[19:51] <ibanezmatt13> External 3.3v, NTX2 on the Pi's 5v?
[19:51] <Jess--> I'm surprised how many were getting it on such low power
[19:51] <fsphil_> the 3.3v regulator on the Pi is known to be wimpy
[19:51] <mfa298> for testing that's worth a try.
[19:51] <Wouter-[pa3weg]> As long as it is line of sight...
[19:51] <fsphil_> 5v from the Pi is just direct from the input voltage iirc
[19:51] <mfa298> external 3v3 for the gps
[19:51] <fsphil_> maybe just with some filtering
[19:51] <ibanezmatt13> ok, I can try that
[19:52] <fsphil_> just make sure the vreg you choose can handle the ublox's peak current usage
[19:52] <fsphil_> and add a capacitor on the input and output sides
[19:52] <fsphil_> to smooth things out
[19:52] <mfa298> from http://elinux.org/RPi_Low-level_peripherals it says 50mA max from the 3v3 pin. Chances are picam and ublox use more than that
[19:52] <ibanezmatt13> almost certainly
[19:53] <fsphil_> ublox certainly a lot more
[19:53] <Wouter-[pa3weg]> I would power the UBlox and NTX separately anyway
[19:53] <Wouter-[pa3weg]> PiCam, no idea about that
[19:53] <mfa298> and I suspect the picam could use a fair bit of that 50mA
[19:54] <ibanezmatt13> fsphil_: I was gonna use another switching reg
[19:54] <Wouter-[pa3weg]> I suggest also reading on http://www.daveakerman.com/
[19:54] <Wouter-[pa3weg]> because he has done the same thing
[19:54] <ibanezmatt13> Wouter-[pa3weg]: You'd power NTX2 and GPS separate from Pi?
[19:54] <fsphil_> get yourself a few LDO regulators anyway
[19:54] <fsphil_> it's worth at least experimenting with
[19:55] <ibanezmatt13> So all I need to make a regulator is a LDO and two capacitors?
[19:55] <fsphil_> yep
[19:55] <ibanezmatt13> What size capacitors?
[19:55] <fsphil_> may not even need the caps, but bad to skip that
[19:56] <mfa298> if you're buying an LDO the datasheet for it should tell you what capacitors you need
[19:56] <Wouter-[pa3weg]> yup, and do not skip them
[19:57] <ibanezmatt13> 3 pins right?
[19:57] <Wouter-[pa3weg]> the regulators may go haywire when missing them (since the NTX generates RF)
[19:57] <Wouter-[pa3weg]> 3 or more, depending on models
[19:57] <fsphil_> yes I've seen that happen
[19:57] <fsphil_> got 5v from a 3.3v reg once :)
[19:57] <Wouter-[pa3weg]> you may have shutdown pins for instance
[19:57] <Wouter-[pa3weg]> or more pins for GND
[19:57] <fsphil_> because I skipped the caps

[19:58] <Ugi_> x-f was Titan really only 1mW?
[19:58] <Wouter-[pa3weg]> but then again, as radio amateuyr you have RF around
[19:58] <Ugi_> I'm much less depressed at my inability to receive it now!
[19:58] <fsphil_> I rarely transmit :)

[19:59] <Ugi_> I did get enough to read "Titan" a few times but nothing more.
[19:59] <Ugi_> but at 1mW that's not bad at all!
[19:59] <Wouter-[pa3weg]> ah well, still. just put the caps there...
[19:59] <fsphil_> I do :)
[19:59] <ibanezmatt13> I will do. Are you sure it's not just worth using the switching reg I have. I have two of them...
[19:59] <fsphil_> switching regs can be a source of noise too :)
[20:00] <fsphil_> though probably less than what you have now
[20:00] <g4fui> Someone commented in the chatroom that they reckoned Titan was 10dB down on what they expected . ..

[20:01] <ibanezmatt13> It's got the capacitors already on it
[20:01] <Wouter-[pa3weg]> kinda big, but usable
[20:02] <Ugi_> Yeah - I have never tried receiving at home before - was thinking it was just because buildings in the LoS.
[20:02] <ibanezmatt13> I believe they're very efficient
[20:02] <Wouter-[pa3weg]> also, keep in mind the efficiency is normally stated at nominal load
[20:02] <Wouter-[pa3weg]> so it might be inefficient at lower currents
[20:02] <Wouter-[pa3weg]> let me check the data sheet
[20:02] <Ugi_> might be true but to get anything from 1mW on a biscuit tin and a bit of wire suggests that hope remains
[20:02] <x-f> Ugi_, Jess-- is one of its authors, he said it was set to 1mW

[20:03] <Ugi_> Hey! Did you recover?
[20:04] <Wouter-[pa3weg]> 68% at 5Vin 3v3 out
[20:04] <Wouter-[pa3weg]> what battery voltage will you use?
[20:04] <cuddykid> Ugi_: no - stuck in a massive tree
[20:04] <Ugi_> :-(
[20:04] <ibanezmatt13> Wouter-[pa3weg]: probably 9v, but I may play safe and go for 12
[20:04] <Ugi_> Any hope?
[20:04] <Wouter-[pa3weg]> makes more sense to convert straight from the battery
[20:05] <ibanezmatt13> so power nothing but Pi Cam off Pi?
[20:05] <cuddykid> Ugi_: we contact a tree surgeon
[20:05] <cuddykid> *we will
[20:05] <cuddykid> but it's ridiculously massive
[20:05] <Wouter-[pa3weg]> at 9V in and 3v3 out, efficiency is around 74%
[20:05] <Ugi_> to climb it or fell it?
[20:06] <Wouter-[pa3weg]> but at 3A load!
[20:06] <ibanezmatt13> it wont be 3a! :P
[20:06] <Wouter-[pa3weg]> nope, thats why your efficiency will be lowere
[20:06] <cuddykid> Ugi_: climb
[20:06] <cuddykid> wouldn't be able to fell it - too many other trees around
[20:07] <Wouter-[pa3weg]> anyway, it will beat LDO´s in efficiency any way
[20:07] <daveake> Ask Steve how that goes :)
[20:07] <ibanezmatt13> that's good enough

[20:40] <Jess--> yes, it was recovered with no problems
[20:40] <Jess--> got a signal and then clean decodes as we got closer
[20:42] <Jess--> position shown on the map is exactly where it was, middle of a field in a marshy bit (so it even had a soft landing)

[21:04] <cuddykid> after last time didn't want to risk under filling so I just kept filling
[21:05] <x-f> did you log the data onboard too or just transmitted?
[21:06] <cuddykid> just transmit
[21:06] <cuddykid> would have been nice to log
[21:07] <mfa298> not sure that it made it much over 30k, trying to work out where rough lines for the few points would meet
[21:07] <cuddykid> yeah
[21:07] <cuddykid> I reckon around 30
[21:07] <chrisstubbs> its hard to guess from the altitude graph
[21:08] <chrisstubbs> upus manual upload makes me laugh
[21:08] <mfa298> maybe slightly over but it's hard to work out with the few data points
[21:09] <chrisstubbs> that reminds me, Jess-- do you know what caused your longitude blip?
[21:10] <cuddykid> didn't mine have a blip too?
[21:10] <cuddykid> no idea what that was about
[21:10] <chrisstubbs> cuddykid, i think that was upu trying to mash together some partials to manually upload
[21:10] <mfa298> cuddykid: I think that was a blip with the manual entries.
[21:10] <cuddykid> ah right
[21:11] <cuddykid> thanks Upu :)
[21:11] <cuddykid> and thanks to all trackers - once again - fantastic work!
[21:11] <cuddykid> such a help
[21:11] <mfa298> well I think on that one the only person who had much luck was M0DTS
[21:11] <Jess--> cuddykid looking at the raw data it dropped the first 2 digits on longitude for one string on titan, cause is so far unknown
[21:12] <mfa298> how big was your stubby antennas ?
[21:12] <cuddykid> mfa298: about 5cm or so
[21:12] <Upu> hey cuddykid
[21:12] <g4fui> Smart thinking by upu to try to rescue some useable data from partials
[21:12] <cuddykid> evening Upu - thanks for your help earlier :)
[21:13] <Upu> did you get it back ?
[21:13] <cuddykid> no
[21:13] <cuddykid> Upu: http://i.imgur.com/PddrdKy.jpg
[21:13] <Upu> oh sheet
[21:13] <cuddykid> yup
[21:13] <cuddykid> it took a while to locate it
[21:13] <Upu> any plans ?
[21:13] <cuddykid> tree surgeon perhaps
[21:13] <Upu> damn those trees are large
[21:13] <cuddykid> I don't have time to go over and show them where it is though
[21:13] <cuddykid> and I don't think they will find it if I just give them co-ord
[21:13] <Upu> the only person receiving any real data was M0DTS
[21:14] <cuddykid> was a bit of a nightmare day tbh - not fun
[21:14] <Upu> he pasted the strings I reconstructed them and recalculated the checksum if missing
[21:14] <g4fui> Nice team work
[21:14] <cuddykid> nice! great job Upu
[21:14] <Upu> are you sure that stub wasn't a RP one ?
[21:14] <Upu> because that was far too weak
[21:15] <cuddykid> one sec - I'll find the one
[21:16] <Upu> there were 6 packets received successfully and decoded
[21:16] <cuddykid> lol
[21:16] <Upu> another 6 reconstructed
[21:16] <cuddykid> can't find it on their site - odd
[21:16] <cuddykid> http://www.lprs.co.uk/wireless/antennas/whip-antennas.html
[21:16] <cuddykid> it was like the first one
[21:16] <Upu> I think you win least amount of telemetry
[21:16] <cuddykid> but
[21:16] <cuddykid> not cylinder - it was thin at one end
[21:16] <Upu> well I use those
[21:17] <cuddykid> almost went to a point at the end
[21:17] <Upu> and they do work
[21:17] <Upu> that doesn't sound right
[21:17] <Upu> they are cylindrical
[21:17] <Upu> oh wait
[21:18] <cuddykid> what I mean is - the width of the ones above remain constant for the length of antenna
[21:18] <cuddykid> the one I used, the width varies
[21:18] <cuddykid> fat in middle
[21:18] <Upu> http://i.imgur.com/LOSMX5l.jpg

[21:21] <daveake> yup
[21:21] <daveake> That got more sentences after it landed than the one today did in the air :)
[21:21] <g4fui> What's the idea of RP?
[21:22] <mfa298> I think it came from the early days of wifi
[21:22] <Hix> it was a ballsup of an idea to separate commercial stuff apparently
[21:22] <mfa298> probably a nice way for the wifi manufacturers to make more money
[21:23] <Upu> it may not be that
[21:23] <eroomde> to stop custom higher gain antennas
[21:23] <g4fui> Are we talking circular polarisation - LH vs RH?
[21:23] <eroomde> which would violate erp
[21:24] <Upu> anyway they don't sell an RP version so that answers that
[21:24] <Upu> you need to get it back and work out what was up with it cuddykid
[21:24] <mfa298> g4fui: they just moved the center pin from the plug to the socket
[21:24] <cuddykid> yeah
[21:24] <g4fui> Ah
[21:25] <g4fui> Male vs female
[21:25] <Hix> "RPSMA connectors were initially introduced to prevent high-gain, professional grade antennas from being connected to commercial grade wireless equipment. Despite this, adapters and RPSMA antennas are both readily available now. Honestly, it wasn’t a brilliant idea and it left consumers with a mess" ironically i read that this morning
[21:26] <mfa298> if you've got a wifi point with a removeable antenna that's almost certainly rp-sma
[21:26] <eroomde> reterminating a bit of coax yourself is hardly a barrier if you're professional
[21:26] <mfa298> Hix, that's what I rembmer the reason being when they started it.
[21:27] <g4fui> All you need is a gender-changer barrel SMA to sort that out ?
[21:27] <Hix> I'm a U.FL convert :)
[21:28] <mfa298> g4fui: it's not just swapping the plugs and sockets over. They removed the pin from the centre of the plug and moved to the socket so it's not compatible with normal sma connectors

[21:38] <g4fui> Well seeing the Saturn V at the Kennedy Space Center was probably the most memorable part of my Florida holiday a while back
[21:38] <SpeedEvil> eroomde: Was this connector the most expensive you've specified?
[21:39] <eroomde> no
[21:39] <eroomde> there was some hermetic bollocks from a cost-plud nuclear industry thing
[21:40] <eroomde> but i think that was expensive because it was done by a huge government contractor whose only setting is expensie
[21:40] <SpeedEvil> Ah.
[21:41] <g4fui> For those guys the unit dB£ was invented
[21:41] <Hix> nickjohnson from #hackvana just put me onto upverter - looks really interesting http://upverter.com/tour/
[21:41] <SpeedEvil> :)
[21:42] <eroomde> yes i'm sure the nsa would love to read all about skylon
[21:42] Action: Hix has a horrible tendency to veer of of C learning and end up doing PCB design too often
[21:42] <SpeedEvil> Interesting.
[21:46] <Wouter-[pa3weg]1> g4fui, like that unit!
[21:51] <Jess--> I wonder if RAF Cottesmore picked up on titan-one circling it for 15 mins http://81.168.22.130/flyby.jpg
[21:53] <g4fui> Hope you didn't have any spy cameras on board!
[21:53] <lz1dev> lol
[21:53] <daveake> I think HABE was running in stealth mode
[21:53] <lz1dev> that path is suspicious :D
[21:53] <eroomde> a bit scary
[21:54] <daveake> Oh, I had some cretin commenting on one of my blog posts saying that I was giving away secrets to terrorists
[21:54] <g4fui> I'm out of here, guys, thanks for the entertainment and banter - TTFN
[21:54] <Jess--> I wonder if it got caught in a thermal

[21:57] <Lunar_Lander> daveake, strange indeed
[21:57] <Lunar_Lander> here in germany we have the flood problem at the moment
[21:57] <eroomde> like an irc channel
[21:57] <Lunar_Lander> and actually some moron wrote to some newspapers that he wants to attack several embankments
[21:58] <Lunar_Lander> police searching for him now of course
[21:58] <Jess--> I know that in hot air ballooning you have to avoid thermals because they will either push you into the ground or take you up to a height where you don't have enough oxygen to breathe (that's why they fly at dawn & dusk... little thermal activity)
[21:59] <Jess--> but not sure of exact heights they go to
[21:59] <Lunar_Lander> what exactly do you suspect to be a thermal?
[21:59] <Lunar_Lander> a circle in the path?
[22:00] <Jess--> spiral in the path and slightly accelerated climb
[22:00] <Lunar_Lander> hm
[22:00] <Lunar_Lander> we had a decrease in ascent rate 10 minutes after liftodd
[22:00] <Lunar_Lander> *liftoff that is
[22:00] <Lunar_Lander> and that persisted until maximum altitude
[22:00] <Lunar_Lander> also don't know why that was
[22:03] <Lunar_Lander> Jess--, and you said that was in the lower stratosphere?
[22:03] <Lunar_Lander> 12 to 17 km?

[22:13] <Hix> I did offer up two ticket on here but nobody wanted them, they've gone now though

[22:35] <Lunar_Lander> nigelvh_, remember my breakout board I designed in EAGLE?
[22:35] <nigelvh_> Yeah
[22:35] <Lunar_Lander> that was a failure
[22:35] <nigelvh_> How come?
[22:36] <Lunar_Lander> the holes for the sensor were too close together to be separated when the required drill was used to drill out the holes

[22:36] <nigelvh_> So either your drill was too large or your holes were too close.
[22:36] <nigelvh_> Probably the first.
[22:36] <Lunar_Lander> hm
[22:37] <Lunar_Lander> a friend of mine in Münster had the boards made for me

[22:38] <Lunar_Lander> at the right
[22:38] <Lunar_Lander> that board was drilled with a too small drill
[22:38] <Lunar_Lander> too small for the sensor legs to fit through
[22:39] <griffonbot> @octothorpe: @fj @tdjohnsn See!! it all adds up! #projecthorus [http://twitter.com/octothorpe/status/343859868136001536]
[22:39] <nigelvh_> And the pins are that close together?
[22:39] <Lunar_Lander> yes
[22:39] <Lunar_Lander> at the left is the actual sensor
[22:39] <Lunar_Lander> see how much the legs bend for 2.54 mm
[22:40] <Lunar_Lander> distance is 1.27 mm
[22:40] <Lunar_Lander> according to the datasheet
[22:40] <nigelvh_> I see what happened. You holes that close together. You need to offset them into two rows, have 1 and 3
[22:40] <nigelvh_> You'll have a hard time putting holes that close together*
[22:41] <nigelvh_> Have 1 and 3 on one row, then offset the second row for 2 and 4.
[22:41] <nigelvh_> What's the part number for that?
[22:41] <Lunar_Lander> the sensor's called HIH-6121 by Honeywell
[22:43] <nigelvh_> Yeah, so you had the size of the rings around the holes too large.
[22:43] <nigelvh_> Look at the datasheet, page 8
[22:43] <nigelvh_> It says specifically what they recommend for hole size and pad size.
[22:44] <Lunar_Lander> yeah I exactly put that into EAGLE
[22:44] <Lunar_Lander> but proabably made a mistake
[22:45] <nigelvh_> Well, if eagle shows the pads as separate, then it was the board manufacturer who didn't do a good job.
[22:45] <Lunar_Lander> ah OK
[22:45] <Lunar_Lander> yeah actually you can't really solder to the board
[22:45] <Lunar_Lander> the solder rather sticks to the iron than the board
[22:46] <nigelvh_> You need flux to get it to stick to the board.
[22:46] <Lunar_Lander> yea
[22:46] <nigelvh_> The board you show in the photo is the cheapest of the cheap.
[22:47] <Lunar_Lander> (and that is actually from an university workshop...)
[22:47] <Lunar_Lander> it was for free, to say the least
[22:47] <nigelvh_> I recommend oshpark. http://oshpark.com/
[22:47] <nigelvh_> They make very nice boards. Not free, but very well priced.
[22:47] <Lunar_Lander> thanks
[22:47] <Lunar_Lander> :)
[22:48] <Lunar_Lander> so I did this to my final remaining sensor http://s.gullipics.com/image/8/2/d/5yv63j-krmrqh-1erc/IMG0218.jpeg
[22:48] <nigelvh_> Just make sure to double check the sizes in your eagle file.
[22:48] <Lunar_Lander> OK
[22:52] <Lunar_Lander> well that worked now :)
[22:52] <Lunar_Lander> I mean the solution you see in the photo
[22:54] <Lunar_Lander> thanks for the link nigelvh_

[23:19] <nigelvh_> A solution to you living in the UK and things taking a while or more money to ship to you?
[23:19] <nigelvh_> No.
[23:19] <nigelvh_> Not the UK, germany.
[23:19] <nigelvh_> In summary, not here in the US.
[23:20] <Lunar_Lander> yea
[23:20] <nigelvh_> I order from digikey, it costs a couple dollars to ship, and it shows up in two days.
[23:20] <Lunar_Lander> yeah
[23:20] <Lunar_Lander> let me check it
[23:21] <Lunar_Lander> 26 euros/piece
[23:22] <nigelvh_> Check out mouser.com
[23:22] <nigelvh_> They've got it for $10 cheaper.
[23:23] <Lunar_Lander> yeah
[23:23] <Lunar_Lander> might be a good idea
