[08:52] <fsphil> I'm detecting a theme
[08:52] <ibanezmatt13> Does anybody know how to delete payload files from Habhub?
[08:53] <daveake> someone does yes
[08:53] <ibanezmatt13> Do you? :)
[08:53] <daveake> Nope

[08:53] <G0TDJ_Steve> Ah ha! Life!
[08:53] <fsphil> you don't delete them, you just replace them if you need to change it
[08:53] <ibanezmatt13> I have like 12 payload files!
[08:54] <daveake> That's quite a lot as you've not flown yet!
[08:54] <ibanezmatt13> Indeed
[08:54] <daveake> I'd best not count mine
[08:54] <fsphil> 12 is more than I've done
[08:55] <ibanezmatt13> The error is that it's expecting less fields than I've told it to but that's not true. The problem is that it's running two sample sentences when there should only be one. I delete the other, save it, reload it, and it's still there
[08:55] <daveake> fewer, ibanezmatt13, not "less" :)
[08:56] <daveake> </pedant>
[08:56] <ibanezmatt13> of course :)#
[08:58] <fsphil> replace the payload doc

[10:32] <cyclops> Hi! Tracker just arrived!
[10:33] <G0TDJ_Steve> Which tracker is that cyclops?
[10:34] <cyclops> Habduino
[10:34] <cyclops> By Upu
[10:34] <G0TDJ_Steve> Oh cool :D What's it like?
[10:35] <cyclops> a arduino shield with the ublox 6 and LMt2
[10:35] <cyclops> I need to test now
[10:35] <G0TDJ_Steve> LOL I have seen the pics :-)
[10:35] <fsphil> take your time :)
[10:36] <cyclops> nothing more to do :P im on holidays
[10:36] <G0TDJ_Steve> Awesome, I'd like to stick around and see it when it appears on tracker but I have to go out. I go with fsphil, take you're time and check it step-by-step
[10:37] <cyclops> Well it lacks instructions so I might first upload soft to arduino
[10:37] <cyclops> and connect
[10:37] <cyclops> :P
[10:37] <G0TDJ_Steve> Sounds likely
[10:37] <G0TDJ_Steve> Damn, gotta go guys. Catch you later.
[10:37] <fsphil> later
[10:37] Nick change: G0TDJ_Steve -> G0TDJ_AFK
[10:38] <cyclops> and to test it, do I need the antenna?
[10:38] <daveake> no
[10:38] <cyclops> i mean Upu suplied a pigtail to make it
[10:38] <cyclops> Can i just plug it?
[10:38] <daveake> That's plenty
[10:38] <cyclops> Nice
[10:38] <cyclops> and though the board has its own regulator
[10:38] <cyclops> an power connector
[10:39] <cyclops> no problem to power from usb right?
[10:44] <UpuWork> ok
[10:44] <UpuWork> yes instructions
[10:44] <UpuWork> either power from USB
[10:44] <UpuWork> OR header
[10:44] <UpuWork> if you do both bad things will happen probably
[10:45] <cyclops> i imagine
[10:45] <cyclops> And to upload software? do i have to plug the habduino?
[10:45] <cyclops> or only arduino
[10:46] <cyclops> Ah and UpuWork thanks for the temp sensor, ill try to use it without breaking anything
[10:46] <UpuWork> you can leave the sheild on
[10:46] <UpuWork> and program it
[10:46] <daveake> same as any other shield
[10:47] <cyclops> Yeah but first time with arduino
[10:47] <cyclops> The only thing Ive made is connect a SD to log random data
[10:48] <daveake> Remind me, when is your launch?
[10:48] <UpuWork> check it works before you start adding additional stuff
[10:49] <Laurenceb> http://s1.b3ta.com/host/creative/13/1375296841/thebirdstwittertrolls.jpg
[10:49] <cyclops> daveake: its on 11-14
[10:50] <daveake> of August?
[10:50] <cyclops> yep
[10:50] <daveake> Go get started then.
[10:50] <cyclops> Arreadi got permission for it
[10:50] <cyclops> *allready
[10:50] <cyclops> Yeah UpuWork
[10:51] <daveake> Usually the cycle goes .... get it working .... test the bejeezus out of it .... apply for permission ... keep testing ... fly
[10:51] <cyclops> And the gps antenna would lose signal if into a 3cm wall sphere?
[10:51] <daveake> with say a 3-month timespan
[10:51] <daveake> or 3 years sometimes
[10:51] <daveake> sphere of what?
[10:52] <fsphil> the lunar cycle

[10:54] <UpuWork> you need all the files
[10:55] <cuclops> do i have to change something?
[10:55] <UpuWork> the call sign
[10:55] <cuclops> or can test directly
[10:55] <UpuWork> and pick the frequency

[10:58] <UpuWork> call sign is 9 chars max
[10:58] <SpeedEvil> One reading per 5s. In other retardation - the quantisation seems to indicate it sends the number as x.xx amps.

[11:28] <daveake> ibanezmatt13 What's a "normal" AA? Have you measured the current used? Remind me what regulator setup you've got.
[11:29] <ibanezmatt13> Duracell standard AA. Just using the switching regulator. Not measured current :/
[11:29] steve_____ (~steve@69.Red-88-14-149.dynamicIP.rima-tde.net) left irc: Quit: steve_____
[11:29] <daveake> Measure it
[11:29] <ibanezmatt13> Do I just put my multimeter in series somehwere like inbetween the battery and the regulator?
[11:30] <daveake> Yes, using the current measuring socket on the DMM
[11:30] <ibanezmatt13> Ok, I'll see what I can do
[11:30] <daveake> This a model A or B?
[11:32] <ibanezmatt13> A
[11:32] <ibanezmatt13> I can't get the multimeter to work daveake
[11:33] <daveake> meaning?
[11:33] <ibanezmatt13> I put the positive lead on the positive terminal of the battery and the negative lead on the VIN+ to the reg
[11:33] <daveake> yes
[11:33] <ibanezmatt13> Didn't work, got a reading of 0
[11:34] <daveake> Did you use the current measuring terminal on the DMM?
[11:34] <ibanezmatt13> I turned the mode to the current mode yes. I think the other
[11:34] <ibanezmatt13> ...
[11:34] <daveake> <daveake> Did you use the current measuring terminal on the DMM?
[11:34] <ibanezmatt13> I think it's in the right socket as the other one is for mains
[11:34] <gonzo_> batt+ to Vin+ would be zero!
[11:34] <ibanezmatt13> I'll try the other onje
[11:34] <daveake> stop
[11:34] <maze> Hammertime!
[11:35] <cuclops> Ok problem solved, I didnt had some libraries
[11:35] <daveake> try and get this right
[11:35] <fsphil> gonzo_: it's in series
[11:35] <fsphil> well it hopefully is
[11:35] <ibanezmatt13> yep
[11:35] <daveake> The sockets should all be labelled for what they're for
[11:36] <ibanezmatt13> There are two negative sockets, one positive. The negative one it's currently in has an V, ohms, A, on it so I think it's right
[11:36] <daveake> That's ... unusual
[11:36] <ibanezmatt13> I'll try changing it
[11:36] <daveake> NO
[11:36] <daveake> Don't just randomly choose sockets
[11:36] <daveake> Link me to a pic or manual for this thing
[11:37] <cuclops> lets plug the habduino tan tan tan
[11:37] <ibanezmatt13> Still not. It's just a standard multimeter from Maplin
[11:38] <x-f> they usually have two positives, one negative
[11:38] <ibanezmatt13> x-f: you're right, they do. My mistake
[11:39] <ibanezmatt13> Ah news daveake. Even with fresh batteries the Pi Cam LED turns on then off immediately
[11:41] <daveake> What's that got to do with the price of bread?
[11:42] <fsphil> mmmm bread
[11:42] <daveake> Got some fresh here
[11:42] <ibanezmatt13> that's the problem I was having
[11:42] <gonzo_> the socket marked 10Ais only there to destroy things, tape it over and don't use it till you understand fully how to use the meter
[11:42] <daveake> So when you say "the batteries last for 2 hours 45" you mean, that's when the cam stopped recording?
[11:43] <ibanezmatt13> err.... yes
[11:44] <daveake> So the Pi was still running?
[11:44] <ibanezmatt13> yes
[11:44] <daveake> Nowt to do with the batteries then
[11:44] <ibanezmatt13> I suspected SD card
[11:44] <daveake> It's probably because the partition is full.
[11:44] <ibanezmatt13> That's the thing.
[11:44] <ibanezmatt13> I expanded the SD card for the whole OS :/
[11:44] <daveake> Rule 1 when asking for help: Define the problem
[11:44] <ibanezmatt13> My apologies
[11:45] <daveake> Takes us down the wrong route

[11:59] <UpuWork> it does work
[11:59] <HixWork> daveake, you aren't aware it is national erroneous and vague awareness day?

[11:59] <daveake> At this rate it's "Dave explodes day"
[11:59] <cyclops> cant get it working

[12:00] <UpuWork> do the LED's blink ?
[12:00] <cyclops> Fist the green one
[12:00] <cyclops> and then the fault red
[12:00] <UpuWork> does fault red blink once a second ?
[12:00] <cyclops> 2 times

[12:00] <cyclops> blinks 4 times a sec
[12:00] <cyclops> stops 1 sec
[12:00] <UpuWork> thats it booting up
[12:00] <cyclops> and again 4 times
[12:01] <UpuWork> after about 10 secs it should just blink once a sec as it gets a lock

[12:02] <cyclops> i do
[12:02] <cyclops> seems i cant get a lock
[12:03] <cyclops> ill plug some spare batts and go far

[12:05] <HixWork> UpuWork, what are the passives on the GPS RF line on the pic? just out of interest
[12:05] <UpuWork> inductor and resistor for the active antenna
[12:06] <HixWork> oh, ok, didn't realie there was active ant
[12:06] <cyclops> ok so the red just booted up as you said
[12:06] <cyclops> BTW the button in the shield is for?
[12:08] <cyclops> no light yet
[12:10] <cyclops> hum
[12:14] <cyclops> no light yet
[12:14] <chrisstubbs> cyclops: iirc the gps antenna is connected using an SMA connector, is it in the right SMA socket (as I seem to remember there were 2?)
[12:15] <cyclops> yes it is

[12:21] <cyclops> red led is now intermitent
[12:22] <cyclops> So now wait till it gets a lock right?
[12:24] <UpuWork> yes
[12:24] <UpuWork> it will go green when it has a lock
[12:24] <cyclops> How much does it usually takes
[12:24] <UpuWork> if you're not getting a lock check GPS antenna is screwed in correctly
[12:24] <UpuWork> and make sure antenna is near a window / outside
[12:24] <UpuWork> depends on if it can see satellite
[12:25] <UpuWork> if its transmitting
[12:25] <UpuWork> the time should be correct
[12:25] <cyclops> lets wait then
[12:26] <cyclops> Did you answered the question about the button ?
[12:26] <UpuWork> its the reset button
[12:26] <cyclops> for arduino?
[12:27] <UpuWork> yes
[12:27] <cyclops> right
[12:27] <cyclops> and the red plug?
[12:27] <UpuWork> remove that to disable the reset button
[12:27] <UpuWork> you don't want reset if its bouncing round in flight
[12:28] <cyclops> so only pulling?
[12:28] <cyclops> it gets out right?
[12:28] <UpuWork> yeah just pull it off

[12:43] <cyclops> too hot to be outside
[12:43] <UpuWork> I have to go out on site
[12:43] <UpuWork> but you need to get the antenna outside
[12:43] <UpuWork> I know it works as I sent you the one i've been testing with
[12:43] <UpuWork> back later on
[12:44] <HixWork> could it be something to do with a different empheris [or is it almanac] due to lat lon differnce being so great?

[12:47] <HixWork> "If the GPS has moved more than a few hundred miles or accurate

[13:07] <cyclops> Rx?
[13:08] <HixWork> Reciever
[13:08] <cyclops> i use the funcube dongle
[13:09] <HixWork> hmm. can you recieve local radio stations on it with SDR#
[13:09] <cyclops> yeah
[13:09] <HixWork> cool
[13:09] <cyclops> oh lost the lock
[13:09] <HixWork> so...
[13:10] <HixWork> damn, unistalled sdr# from work pc
[13:10] <HixWork> sec
[13:10] <cyclops> im using sdrcharp and dlfldigi
[13:11] <HixWork> cool - settings should be similar to this img http://i.imgur.com/m7xrdF2.png
[13:12] <HixWork> and you should see someting on SDR# waterfall - somewhere near the frequency of the LMT2
[13:14] <cyclops> lets see
[13:14] <HixWork> are you using the standard code as stock from github?
[13:15] <HixWork> if so i believe channel 12 434.496 is the default
[13:15] <HixWork> so 434.496MHz on USB
[13:15] <cyclops> yes i do
[13:15] <cyclops> i think its 15 the def
[13:17] <cyclops> nothing
[13:17] <HixWork> sorry, my typo yes 15
[13:17] <HixWork> 434.646
[13:17] <HixWork> ignore dl-fldigi for now
[13:17] <cyclops> got something
[13:17] <HixWork> warbling sound yes?
[13:18] <HixWork> remember use the zoom in SDR#
[13:18] <cyclops> thought intermitent
[13:18] <cyclops> a sec turning on speakers
[13:18] <HixWork> like this http://tenbus.co.uk/icaruscapture_30secs.mp3
[13:19] <cyclops> beeeeeeeppppp
[13:19] <cyclops> more or less
[13:19] <HixWork> what MHZ do you have on SDR#, tried moving it around a little? got a grab image of SDR#?
[13:20] <cyclops> 432,6mhz
[13:21] <HixWork> hmm. nowhere near, go to 434.646
[13:21] <HixWork> you should see something there like my image
[13:22] <fsphil> todays local met sonde has landed on the Isle of Arra
[13:22] <fsphil> +n
[13:22] <fsphil> don't fancy going after that one
[13:22] <HixWork> namy HAB points
[13:22] <HixWork> *many
[13:22] <fsphil> yes I suspect the met office are ahead in points
[13:22] <HixWork> heh
[13:23] <fsphil> oh wait the signal has come back
[13:23] <HixWork> got anything yet cyclops I have to go to a meeting in a minute
[13:23] <cyclops> Nope HixWork
[13:23] <cyclops> maybe its the antenna
[13:23] <cyclops> Its only the pigtail
[13:23] <HixWork> hmm, nothing on the waterfall? shouldn't need one at that range
[13:24] <cyclops> ill continue triyin
[13:24] <x-f> fsphil, in a tree on an island?
[13:24] <fsphil> x-f: would need to be a big tree
[13:25] <fsphil> it's not decoding so I can't see if it's moving
[13:26] <x-f> how far is it from you?
[13:26] <HixWork> cyclops, try without the pigtail first
[13:27] <HixWork> module should have enough power next to FCD
[13:27] <fsphil> x-f: I'd guess around 150km
[13:27] <cyclops> well i have the antenna plugged to the FCD+
[13:27] <HixWork> i mean the habduino
[13:27] <cyclops> yeah
[13:28] <HixWork> what you have the lead connecting them?
[13:28] <mfa298> at that distance you should be able to hear it with no antenna on either item.
[13:28] <cyclops> i have the car antenna
[13:28] <cyclops> and next to it the habduino
[13:28] <HixWork> what is on the habduino?
[13:28] <fsphil> signal's gone again
[13:29] <HixWork> remove it.
[13:29] <cyclops> in the habduino nothing
[13:29] <cyclops> got a yellow waterfall
[13:29] <HixWork> and you have the settings in SDR# on USB with filter ~3000 yes?
[13:30] <cyclops> yes
[13:31] <HixWork> So you can see a yellow line on 434.646 but not hear it?
[13:31] <cyclops> i hear beeps
[13:31] <HixWork> like the mp3?
[13:31] <cyclops> now its gone
[13:32] <cyclops> only a continous beep
[13:32] <HixWork> what is powering the habduino?
[13:32] <cde> habperes
[13:33] <HixWork> oh, forget that, it has step-up
[13:33] <HixWork> cde :D
[13:33] <cyclops> strange thing
[13:33] <cde> hablol
[13:33] <HixWork> are you zoomed in on SDR#
[13:33] <HixWork> so you can see accurately

[13:40] <daveake> Just checking the log .... SDR# no signal from the habduino?
[13:40] <daveake> And this is the Funcube Pro+ ?
[13:41] <HixWork> errrm there was one on the wrong freq
[13:41] <HixWork> but not sure now...
[13:41] <HixWork> FCD+ apparently
[13:41] <cyclops> got
[13:41] <daveake> And has the "Swap I & Q" checkbox been checked like it says in the instructions?
[13:41] <cyclops> something
[13:41] <HixWork> excellent
[13:41] <HixWork> cyclops, ^^
[13:42] <daveake> 'cos if that isn't checked it will appear at the wrong frequency
[13:42] <daveake> and then it won't decode without Rv or LSB being selected
[13:42] <HixWork> cyclops, did you see what daveake just said?
[13:43] <HixWork> cyclops, below step size, tick box "Swap I & Q"
[13:43] <daveake> And when you drag the LO frequency the signal will zip off in the other direction
[13:44] <cyclops> ok swap ticked
[13:44] <cyclops> lost signal
[13:44] <daveake> This is actually documented - http://www.funcubedongle.com/MyImages/FCD2ManualV3.pdf
[13:44] <cyclops> (before doing)
[13:44] <daveake> but then nobody reads instructions these days
[13:45] <HixWork> what channel are you set to? did you change it?
[13:46] <HixWork> daveake, all items should come with RTFM in huhe fluoro letters on the product which is massively taped up so you have no choice but to read RTFM as you unwrap it
[13:46] <cyclops> got something
[13:46] <cyclops> i set to 0 chanel
[13:46] <cyclops> and i have signal at 433.8mhz
[13:47] <cyclops> like the mp3
[13:48] <cyclops> see the 2 rtty lines
[13:48] <HixWork> cool, so now it should work in dl-fldigi with patch lead between headphones and mic in
[13:48] <HixWork> may have to tweak mic level to get it clean
[13:50] <cyclops> what about virtual cable?
[13:50] <daveake> That works
[13:50] <daveake> It's what I use
[13:50] <HixWork> keep it simple to start. once you have things working, then try it

[14:06] <eroomde> any interesting flights in the last week?
[14:07] <cyclops> this is awseme
[14:07] <fsphil> my auntie flew over from scotland
[14:07] <Willdude123> eroomde I finished L'Etranger
[14:07] <daveake> eroomde, Nah Leo hasn't flown anything for days
[14:07] <DrLuke> maybe they have to loose a couple more spacecraft before they get it
[14:07] <HixWork> 2 apaches quite low over the office earlier tooled up
[14:07] <eroomde> Willdude123, good work!
[14:07] <cyclops> thought i lost lock (its too hot outside to left there the tracker)
[14:07] <eroomde> what do you think?
[14:07] <DrLuke> HixWork 2 apaches flew over my home in 150m a few days ago
[14:08] <Willdude123> Of the book?
[14:08] <Willdude123> I think it was pretty good,
[14:08] <DrLuke> theyre surprisingly quiet
[14:08] <Willdude123> Anyone here know of any good intro to calculus books?
[14:09] <HixWork> sec Willdude123
[14:09] <HixWork> Willdude123, https://www.dropbox.com/s/ud6mb7x5jzguake/Calculus.pdf

[14:09] <eroomde> I'm not sure about books willdude (i can recommend loads once you have the basics) but khan academy might be good
[14:09] <eroomde> i quite like prosey books rather than huge textbooks for that kind of thing
[14:10] <HixWork> eroomde, he produced this t'other day http://leobodnar.com/balloons/files/IMG_1431.jpg
[14:10] <eroomde> they sort of play thr role of a lecturer, whereas textbooks can sometimes feel like a appendix to the lecturewr without providing the lectures
[14:10] <Willdude123> Hmm
[14:10] <eroomde> HixWork, what is it?
[14:10] <cyclops> The GPS works
[14:10] <Willdude123> Looking at 18.01SC
[14:10] <cyclops> Got my exact locaction
[14:10] <eroomde> LeoBodnar, you around?
[14:11] <HixWork> a DF beacon. getting rid of need for GPS
[14:11] <Willdude123> Apostol's calculus sounds good but it's a bit deep-endish
[14:11] <HixWork> was my understanding
[14:11] <eroomde> we've never needed gps :D
[14:11] <eroomde> it's just a modern convenience :)
[14:11] <DrLuke> eroomde: Id go for tiny
[14:11] <eroomde> ?
[14:11] <HixWork> fair point well made eroomde I'm still a road atlas user
[14:11] <DrLuke> that thing is tiny
[14:11] <eroomde> ah right
[14:12] <eroomde> we have tracked habs just with 1Hz beepers before
[14:12] <eroomde> tis a fun thing to do, keeps you sharp
[14:12] <DrLuke> I wish I didnt have a 10 sec ping
[14:12] <eroomde> but having 2 chase cars helps a really great deal
[14:12] <cyclops> lunch time
[14:12] <cyclops> thanks for the help

[14:13] <eroomde> maybe
[14:13] <eroomde> i have not read it myself but it looks good just from the diagrams
[14:14] <DrLuke> I'm thinking about resuming work on my first hab soon, as my financial situation turned to the better
[14:15] <HixWork> eroomde, "[08:03] <LeoBodnar> It's an HF transmitter with Domino mode"
[14:15] <HixWork> 31/07
[14:15] <eroomde> coolio
[14:15] <DrLuke> whats domino mode
[14:15] <eroomde> so it's going to be yagi-direction tracked?
[14:16] <eroomde> or ToF?
[14:16] <Darkside> it wasnt designed for a balloon launch
[14:16] <Darkside> its for falconry
[14:16] <Darkside> but he might fly it on 13.56MHz
[14:17] <eroomde> fairynuff
[14:18] Action: mfa298 wonders how many people have a 20m beam on a rotator for DF with that.

[14:21] <costyn> hello all
[14:21] <UpuWork> hey costyn
[14:21] <costyn> HixWork: so what data does it send ?
[14:21] <HixWork> greetings costyn how is the world of warm islands
[14:22] <costyn> HixWork: warm :) actually, it's quite doable.
[14:22] <costyn> HixWork: when there's enough wind
[14:22] <HixWork> costyn " It's an HF transmitter with Domino mode" is as far as my understanding extends
[14:23] <eroomde> i've been in puglia for the last week and it was 38-40 most days
[14:23] <HixWork> have you ssorted that offshore speedboat yet ;p
[14:23] <eroomde> you live or die by there being a breeze
[14:23] <HixWork> too hot for the local food?
[14:23] <UpuWork> oh at least it was nice and cool there
[14:23] <costyn> HixWork: no :) have seen some really nice ones floating around though :)
[14:23] <UpuWork> must be a shock coming back to UK
[14:23] <HixWork> costyn, I'll bet.
[14:23] <costyn> HixWork: it's weird... the chasm between the really wealthy and the really poor is very evident
[14:24] <costyn> luckily there's a large middle class here too
[14:24] <HixWork> isn't that most of the world outside Europe?
[14:24] <costyn> I guess so
[14:24] <eroomde> HixWork, no, plenty of local food
[14:24] <HixWork> though it appears to be more and more prevalent in Eu these days too costyn
[14:25] <HixWork> good work eroomde :D
[14:25] <eroomde> also we tended to do 3pm-6am
[14:25] <eroomde> as days
[14:25] <eroomde> lunch, afternoon somewhere, sea, drinks, dinner, out
[14:26] <costyn> HixWork: yea, although it becomes more evident on a small island like this where you see both ends regularly
[14:26] <costyn> HixWork: back home you don't run into the fabulously wealthy that often
[14:27] <HixWork> costyn, yeah, very lonely here ;p
[14:28] <HixWork> eroomde, did you ever hear about the McD's that opened in Puglia? It lasted about 2 years then closed as the locals refused to eat it's crap bread, preferring their own local
[14:28] <HixWork> baked stuff
[14:29] <fsphil> sadly that didn't happen here
[14:29] <eroomde> i can beleive that
[14:29] <fsphil> the scary clown does rather well here

[14:29] <eroomde> hmm but there was one in Bari
[14:30] <eroomde> tho i didn't really like Bari, we just had to kill time there in between returning the rental car and getting the flight back
[14:30] <costyn> eroomde: might be because of backpackers? i once passed through Bari on my way to Greece with a boat
[14:30] <HixWork> Capello da Gendarme - genius
[14:31] <eroomde> yes it had the feel of people passing through
[14:31] <eroomde> lots of very crowded tiny streets full of contatnly brning shrines and people shouting 'bedandbreakfast!' at you
[14:31] <eroomde> you forget you're theoretically in a modern european country
[14:31] <eroomde> though i've always felt differently about italy...
[14:31] <fsphil> italy isn't that modern
[14:32] <fsphil> they've clung on to the 80s
[14:32] <eroomde> indeed
[14:32] <gonzo_> 50's!
[14:32] steve_____ (~steve@69.Red-88-14-149.dynamicIP.rima-tde.net) left irc: Quit: steve_____
[14:32] <HixWork> a lot of it reminds me of rural Eire, apart from the food and weather
[14:33] <eroomde> it is quite backwards. you can see how the corrupt man with the nice smile can get elected
[14:33] <eroomde> sort of more in common with countries to its south than its north
[14:33] <Willdude123> eroomde on that page, I don't understand how unrolling the rings makes a triangle.
[14:33] <eroomde> you see how all the rins are progressively smaller from the outside in?
[14:33] <eroomde> rings*
[14:34] <Willdude123> Yes
[14:34] <eroomde> so the smallest ring, when unrolled, will make a short line
[14:34] <eroomde> the next smallest one, when unrolled, will make a slightly longer line
[14:34] <eroomde> with me?
[14:34] <Willdude123> Yes
[14:35] <eroomde> and so you eventually get this sort of set-of-stairs effect
[14:35] <eroomde> that is roughly the shape of a triangle, but is actually strairs
[14:35] <eroomde> with me?
[14:35] <Willdude123> Kinda
[14:35] <eroomde> stairs*
[14:35] <eroomde> well, are you happy that you get that set of strairs?
[14:35] <eroomde> forget about triangles for the min
[14:35] <Willdude123> Not really.
[14:35] <eroomde> ok
[14:36] <eroomde> well, imagine this dash is the inner ring unrolled
[14:36] <eroomde> -
[14:36] <Willdude123> Yes
[14:36] <eroomde> and then the ring that was immediately outside it has a slightly larger circumference
[14:36] <Willdude123> Ah right I kinda get that.
[14:36] <eroomde> so when you unroll it, it is slightly long
[14:36] <Willdude123> So --
[14:36] <eroomde> longer*
[14:36] <eroomde> --
[14:36] <eroomde> yep
[14:36] <eroomde> so so far we have
[14:36] <eroomde> -
[14:36] <eroomde> --
[14:36] <Willdude123> then --
[14:36] <Willdude123> wait then ---
[14:37] <Willdude123> then ----
[14:37] <eroomde> exactly
[14:37] <Willdude123> then -----
[14:37] Last message repeated 1 time(s).
[14:37] <Willdude123> *------
[14:37] <Willdude123> then -------
[14:37] <eroomde> so, it looks like this is you progressively unroll the rings, from outer to inner, and place them beneath the previous one:
[14:37] <eroomde> -
[14:37] <eroomde> --
[14:37] <eroomde> ---
[14:37] <eroomde> ----
[14:37] <eroomde> -----
[14:37] <eroomde> ------
[14:37] <eroomde> -------
[14:37] <eroomde> etc
[14:37] <Willdude123> Ah and that's a triangle.
[14:38] <eroomde> yep
[14:38] <Willdude123> So it keeps on going
[14:38] <Willdude123> -
[14:38] <Willdude123> --
[14:38] <Willdude123> ---
[14:38] <Willdude123> ----
[14:38] <Willdude123> -----
[14:38] <Willdude123> ------
[14:38] Last message repeated 1 time(s).
[14:38] <Willdude123> *-------
[14:38] <eroomde> yep
[14:38] <Willdude123> ---------
[14:38] <eroomde> so, can you link me back to that page?
[14:38] <eroomde> i have lost it
[14:38] <Willdude123> ----------
[14:39] <Willdude123> Sure

[14:40] <eroomde> so you're happy with how we get from the circles to the unrolled rings bar-chart

[14:41] <Willdude123> Yes
[14:41] <eroomde> cool
[14:42] <eroomde> so, are you happy with base of that bar chart being the same length as the radius of the circle?
[14:42] <eroomde> i.e. r
[14:42] <Willdude123> One sec have to disconnect mosh again due to 20k internet.
[14:43] <fsphil> wasn't mosh designed to handle bad internet?
[14:44] <Willdude123> Yes, except when irssi messes up over ssh it really messes up.
[14:45] <fsphil> I find that if the weechat window gets a bit corrupt, resizing it fixes it
[14:45] <fsphil> there's probably a key for redrawing the screen but this is just as handy
[14:45] <Willdude123> As in the no bottom bar and bottom message keeps changing rather than pushing it up into the scrollback.
[14:45] <Willdude123> Right

[15:45] <fsphil> between 434.200 and 434.600 is normally fine

[16:16] <cyclops_> not 30c here in the inside
[16:16] <cyclops_> Ill power on the air conditioner
[16:17] <x-f> cyclops_, when you made the payload doc, there was a way to tell habitat that the string is invalid, if the satellites field is <3, for example

[16:44] <chrisstubbs> Im in the process of designing a new board with a tps61201 regulator onboard
[16:44] <G0TDJ_Steve> Coolio. Need a Beta tester? ;-)
[16:45] <chrisstubbs> I have a few more of those chinese regulators on their way which are surplus to requirements now. Shall i forward one onto you to use on that board?
[16:45] <chrisstubbs> you can float it with just one aa using that but will only last about 10 hours
[16:45] <G0TDJ_Steve> That would be great, thanks
[16:45] <chrisstubbs> 10 hours with uBlox PSM that is, will be considerably less without
[16:46] <G0TDJ_Steve> My first launch is to get all the procedures in place and to actually have a go. Whats that Chris? PSM?
[16:46] <chrisstubbs> Have you made any progress soldering that all up?
[16:46] <chrisstubbs> power saving mode
[16:46] <chrisstubbs> puts the gps into 1 second cyclic mode
[16:46] <G0TDJ_Steve> Oh, of course. NOt soldered any yet. I'll do it all together when the GPS arrives (sometime!)
[16:46] <chrisstubbs> Ahh okay :)
[16:47] <chrisstubbs> If you are going to use the boost reg dont bother soldering on the TLV regulator
[16:47] <G0TDJ_Steve> Because of my lack of space, it's easier to do things in-one-go rather than getting stuff out, putting back out, back, loosing bits etc.

[18:47] <LeoBodnar> Thanks for trying! We'll do it properly again with a new PCB.
[18:48] <Lunar_Lander> probably I can still connect it as it has "legs" like the PCB model
[18:48] <LeoBodnar> Yes, 13.553 USB
[18:48] <fsphil> I'm at 13.553 USB dial
[18:48] <fsphil> what offset?
[18:48] <LeoBodnar> It must be a nanowatt, not 10mW :)
[18:49] <fsphil> yea you should at least be able to receive it LOS
[18:49] <LeoBodnar> Note: bench testing does not cancel proper range check :)
[18:50] <Rob_m0dts> i cant talk to many locals more than 10km away on 20m with 100W! so not hearing anything is to be expected... any EU stations listening?

[18:51] <Lunar_Lander> :(
[18:51] <LeoBodnar> I need to investigate and report back when actual PCBs arrive, this was a prototype.
[18:51] <Lunar_Lander> yea
[18:52] <Jonathan_G4KLX> Heights such as these affect ionospheric propagation via HF very little.
[18:53] <LeoBodnar> I think something is wrong with the TX, I have done power measurements into dummy load but not actual range check. It was very faint during launch but I thought this was my receiver
[18:53] <Rob_m0dts> ok well i'l leave it running for a bit and see if anything happens.

[19:00] <Lunar_Lander> and that was an old 4030 that flew into the stratosphere last time
[19:00] <LeoBodnar> Just a PLL chip
[19:01] <KT5TK_QRL> No amp & filter? What type?
[19:02] <LeoBodnar> CDCE913 with LPF
[19:03] <KT5TK_QRL> Did you check if the filter was good?

[19:05] <LeoBodnar> Ihave looked at the spectrum and output waveform
[19:06] <LeoBodnar> but a lot of things have happened after that :)
[19:06] <KT5TK_QRL> I've been using a DDS on shortwave for PSK31, but I also had a 100mW Amp. That worked quite well
[19:07] <KT5TK_QRL> A DDS mayconsume more power though

[19:23] <MrCraig> Hi all, been a while.
[19:24] <MrCraig> I see a flight due to launch any time now? best of luck.
[19:25] <fsphil> howdy MrCraig
[19:28] <MrCraig> hi there fsphil
[19:29] <fsphil> still over in Chuck Norris land?
[19:29] <MrCraig> yup - just ate at Raising Cane's with a picture of the Norris on the wall.
[19:29] <fsphil> haha
[19:30] <fsphil> Walker Texas Ranger was just on the telly here
[19:30] <MrCraig> I don't know that anyone here watches it... the same as Dallas. Though I have driven by the ranch a few times.
[19:31] <MrCraig> I'm actually at work right now - *ahem* working.
[19:31] <fsphil> yeaaaa
[19:31] <MrCraig> Timezones suck, I think we should just do away with them.
[19:31] <fsphil> UTC for all
[19:32] <MrCraig> no way, GMT all the way. I'm not giving up on Greenwich just because someone in Europe didn't like it being based in England.

[19:33] laekur (~laekur@unaffiliated/laekur) left irc: Client Quit
[19:33] <MrCraig> Having said that - I do enjoy it being light when I go to work and light when I come back, and remaining light into the late evening.
[19:34] <fsphil> I thought it got dark early nearer the equator in summer than the higher latitudes
[19:35] <SpeedEvil> It does.
[19:35] <MrCraig> Certainly doesn't appear that way. It's reasonably consistently bright for large portions of the day, year round. I can leave the house at 7pm and it feel like noon - by about 9-9:30 it's getting darker.
[19:35] <SpeedEvil> And much, much more abruptly.
[19:35] <fsphil> it's light here until 10:30 in june/july
[19:36] <SpeedEvil> I was just outside picking blackcurrants with no problems at all
[19:36] <MrCraig> There's a fair point, it might get darker earlier in those summer months actually, but seems to stay bright later in Oct/Nov/Dec
[19:36] <SpeedEvil> Well - other than the fact I kept dropping them

[19:37] <fsphil> the nights are definitly getting darker now though
[19:38] <MrCraig> I just got involved in the Dallas Makerspace HAB project (by involved I mean started talking to a couple of the members of the sub-group) - I'm kinda disappointed that they plan to fly a 350g and I'm going to guess at around 1kg payload.
[19:38] <MrCraig> Cheaper on gas though.

[19:40] <MrCraig> I won't be building another until November now (getting married in oct), but as an interesting side project I'm trying to read a netbook camera with an arduino for in-flight transmission of images.
[19:40] PH3V (~phv@i225084.upc-i.chello.nl) joined #highaltitude.
[19:41] <fsphil> that sounds rather difficult
[19:41] <fsphil> those cameras tend to be USB don't they?
[19:41] <MrCraig> I know you have experience in this, which is why I mention it :) It is a USB interface yes, I think 2Mpixel
[19:42] <fsphil> yea, I've wondered about some kind of UVC interface - most cameras seem to be UVC these days
[19:42] <MrCraig> You think the baud rate from the camera will be too high?
[19:43] <SpeedEvil> I've not seen a camera which will support 1.5mbit mode
[19:43] <fsphil> if the camera supports the slower modes it should be possible
[19:43] <SpeedEvil> you need to support 12mbps USB
[19:43] <fsphil> but, the problem will be memory
[19:43] <MrCraig> SD card
[19:43] <SpeedEvil> And you generally need to read out a whole image sequentially at full rate.
[19:44] <SpeedEvil> You cannot slow down, or the image breaks down
[19:44] <fsphil> SD card probably wouldn't be fast enough
[19:44] <SpeedEvil> There is no buffer
[19:44] <MrCraig> ahh
[19:44] <fsphil> you'll need external memory
[19:44] <MrCraig> then it just might have to become a raspberry pi project
[19:44] <fsphil> enough for the whole frame
[19:44] <SpeedEvil> You are absolutely not going to do it on an arduino.
[19:44] <SpeedEvil> Unless you have lots and lots of external hardware.
[19:44] <MrCraig> My concern with Pi is power consumption.
[19:44] PH3V (~phv@i225084.upc-i.chello.nl) left irc: Ping timeout: 246 seconds
[19:45] <fsphil> the Pi.A is pretty good if you replace its regulator
[19:45] <SpeedEvil> Or even the Pi B
[19:45] <fsphil> the PiCam doesn't need 5v
[19:45] <SpeedEvil> You can just turn off USB and power use goes down to what the As is
[19:45] <fsphil> though a USB webcam might
[19:45] <MrCraig> and Pi should be easy to write code for.
[19:45] <SpeedEvil> Not much point of course - unless you happen to have a B
[19:45] <fsphil> yea the Pi is nice to code on
[19:46] <fsphil> the only issue might be interfacing both the NTX2 and GPS
[19:46] <fsphil> there is only one uart
[19:46] <fsphil> and you can't reliably do software timing for rtty
[19:46] <SpeedEvil> Yes you can.
[19:46] <MrCraig> well I'm looking at transmitting using HX-1, and there's an audio port that I'm thinking might make a modulator
[19:46] <fsphil> yes audio out works too
[19:46] <SpeedEvil> http://pythonhosted.org/RPIO/pwm_py.html
[19:46] <SpeedEvil> You can do really accurate timing using the DMA unit
[19:47] <fsphil> I can't see a way of doing a sequence of bytes with that SpeedEvil
[19:47] <fsphil> it seems to just repeat a pattern
[19:48] <SpeedEvil> Well - yes - but there is no inherent reason for that.
[19:48] <SpeedEvil> You can easily use similar code to do arbitrary waveform generation.
[19:48] <SpeedEvil> It's just DMA from memory, after all.
[19:48] <fsphil> true
[19:48] Geoff-G8DHE-M (~Geoff-G8D@212.183.128.81) joined #highaltitude.
[19:48] <MrCraig> Any of the pi variants come with dual usb on-board? (second would be useful for control of hardware, turning on and off the radio for example)
[19:48] <fsphil> if it can be done so that it doesn't repeat it
[19:48] <fsphil> and there was a way to detect when it has finished
[19:49] <fsphil> then it would work good
[19:49] <fsphil> MrCraig: you have GPIO pins for that
[19:49] <fsphil> much easier than using USB
[19:49] <SpeedEvil> fsphil: Well - you can easily setup a whole sentance in DMA.
[19:50] <MrCraig> ok, I guess the choice is for pi then :-)
[19:50] <fsphil> that bit is easy enough SpeedEvil -- and I guess knowing when it's finished is just something that python code hasn't done yet
[19:50] <Laurenceb_> is B9 launching?
[19:50] <fsphil> it's launched Laurenceb_
[19:50] <fsphil> very very weak signal
[19:50] <LeoBodnar> Nah, no TX
[19:51] <Laurenceb_> its on HF?
[19:51] <LeoBodnar> Supposed to be
[19:51] <SpeedEvil> fsphil: Of course - if the GPS can be set to 50bps...
[19:51] <fsphil> haha
[19:51] <SpeedEvil> I mean one on RX, one on TX
[19:51] <SpeedEvil> Oh - I forgot
[19:52] <SpeedEvil> The Pi serial thingy doesn't do 50.
[19:52] <fsphil> it does
[19:52] <SpeedEvil> Or am I thinking of the BBB
[19:52] <SpeedEvil> I'm thinking of the BBB
[19:52] <fsphil> it did for me anyway, others had problems with it

[21:57] <ibanezmatt13> Bad idea?
[21:57] <mfa298> ibanezmatt13: with the process that makes the camera start recording you could always get it to test if there's enough free space before starting a recording - although it might be a bit close to launch date to change code too much

[21:59] <ibanezmatt13> I thought of that mfa298 but in the end I just couldnt be bothered. I certiainly will for a next flight but it looked ok. It kept trying to record but didn't save anything so it should be too much of an issue
[21:59] <daveake> You just don't have enough space
[21:59] <daveake> Check with df
[22:00] <ibanezmatt13> I think I may need to add something to my code though
[22:01] <ibanezmatt13> In the bash script I'll add something that checks for a duplicate file name. The Pi's unreal time OS has given me some issues like that
[22:01] <ibanezmatt13> Such as overwriting previous video files with the same name
[22:01] mikestir (~quassel@cpc10-brmb8-2-0-cust107.1-3.cable.virginmedia.com) left irc: Remote host closed the connection
[22:03] <mfa298> future addition for your code: set the system clock (date and time) from the gps if its not set
[22:03] Action: mfa298 makes note to add that into my code
[22:03] <ibanezmatt13> that's a brilliant idea. I'll be sure to do that mfa298
[22:04] <mfa298> if you want the date I think you'll need to read another string as well.
[22:04] <ibanezmatt13> Time will be plenty
[22:05] <[1]iain_g4sgx> I just tried to edit my payload doc but it just created a duplicate. Is there a way to edit or delete them? Being open access probably not.
[22:06] <ibanezmatt13> I had the same problem earlier today :) couldn't fix it
[22:07] <craag> Any edit creates a new payload doc
[22:07] <craag> That's a feature :)
[22:07] <daveake> <mfa298> future addition for your code: set the system clock (date and time) from the gps if its not set
[22:07] <daveake> ^^ do this
[22:08] <ibanezmatt13> I will do it tomorrow definitely
[22:08] <daveake> Then you can see when pix were taken so you can find the altitude etc
[22:08] <ibanezmatt13> good idea, how will I keep a record of the altitude?
[22:08] <ibanezmatt13> Nevermind :)
[22:08] <daveake> erm habitat
[22:08] <ibanezmatt13> yeah
[22:09] <daveake> Or you can write to a file of course
[22:09] <daveake> easy peasy
[22:09] <ibanezmatt13> thought of that. Would a few thousand lines of data not harm space on the SD?
[22:10] <fsphil> how big is your code?!
[22:10] <daveake> How about adding up how many bytes that is, roughly, and tell us?
[22:10] <ibanezmatt13> sure :)
[22:11] <cyclops> ordered another sensor
[22:11] <cyclops> lets see if i wire it correctly
[22:11] <daveake> just the one?
[22:11] <daveake> optimistic :)
[22:11] <ibanezmatt13> daveake: I never got mine working on the Pi n chips
[22:11] <cyclops> and i saw i wired it wrongly
[22:12] <cyclops> tracker works so no problem
[22:12] <daveake> ibanezmatt13 What did you do to get it working?
[22:13] <ibanezmatt13> cut a track as we said and soldered a wire from the middle pin of the sensor to GPIO4. Still nothing
[22:13] <daveake> NOT enough
[22:13] <ibanezmatt13> I thought it was
[22:13] <daveake> What did you do to the OS so it saw the new device?
[22:13] <daveake> I did link you to a page that tells you exactly what to do
[22:13] <ibanezmatt13> Nothing, I thought with the code I had it was automatic. I read that page

[22:20] <ibanezmatt13> daveake: everywhere I look, the Pi should just recognise it anyway apparently
[22:20] <daveake> It starts with "updating the kernel". That's "plug and go" is it?
[22:20] <ibanezmatt13> I've done an update and upgrade
[22:20] <daveake> No you need to run modprobe try adding that to your search
[22:20] <ibanezmatt13> I ran modprobe in the code
[22:21] <daveake> So when I asked what you'd done, and you said nothing ....
[22:22] <daveake> Look, if you've followed the instructions, and it doesn't work, and it's definitely on GPIO4, and you've not shorted the pin or anything, then you've done as much as you can
[22:22] <daveake> But I'm guessing that somewhere along the line you've not followed those steps exactly

[22:23] <ibanezmatt13> I think that's it. I'll check again but as far as I can tell, everything was followed correctly
[22:23] <daveake> And if you have done them, and it didn't work, come back to me with which step (on that page) didn't work
[22:23] <ibanezmatt13> Will do
[22:24] <daveake> I've made a few Pi trackers with that chip and no problems, so it really should work
[22:24] <ibanezmatt13> The error was "index not in range" and I got that after this line device_folder = glob.glob(base_dir + '28*')[0] in this code which I used exactly http://learn.adafruit.com/adafruits-raspberry-pi-lesson-11-ds18b20-temperature-sensing/software daveake
[22:25] <daveake> So the code then? ALL the previous bits on that page worked?
[22:25] <ibanezmatt13> As far as I can tell yes
[22:25] <ibanezmatt13> But I'll check it out tomorrow again
[22:26] <daveake> Well use the code on that page instead of the Adafruit stuff
[22:26] <ibanezmatt13> Ok, will do
[22:26] <daveake> Mine is in C but effectively is the same as on that page
[22:27] <ibanezmatt13> I understand C a lot more now, I've been doing quite a bit
[22:27] <ibanezmatt13> My Dad was teaching me about how computers and memory worked with registers and gates. Fascinating stuff
[22:27] <ibanezmatt13> Pointers now make a lot more sense :)
[22:27] <ibanezmatt13> Well, not a lot more but hey
[22:28] <mfa298> wait 'til you get into pointers to pointers and pointers to functions.

[22:31] <ibanezmatt13> When shall I put an announcement on the mailing list?
[22:33] <Survivor> Hey guys.. I was looking for some baseline requirements for a hot air balloon.. can you guys help me?
[22:33] <daveake> wrong conf
[22:34] <daveake> er
[22:34] <daveake> channel
[22:34] <ibanezmatt13> hot?
[22:34] <Survivor> its the high altitude channel
[22:34] <daveake> h2 gone wrong
[22:34] <ibanezmatt13> lol
[22:34] <daveake> hot air balloons probably have their own channel

[22:35] <daveake> ibanezmatt13 Announce when you're reasonably sure of launching
[22:36] <ibanezmatt13> we'r sure
[22:36] <daveake> Say 4-7 days before

[22:39] <Survivor> ahan
[22:39] <Survivor> I see
[22:39] <daveake> Is this for a theoritical hot air balloon?

[22:39] <Survivor> yea theoritical
[22:39] <daveake> go up come down
