[00:32] <ka9szx> You have to remember Joe I am not familiar with the program. I will have to play with it but like the idea it pulls up the wind information and I do not have to manually plug it in.
[00:32] <NSS-52> what is the symbol by kalamaoo?
[00:33] <NSS-52> true
[00:33] <NSS-52> looks interesting

[00:34] <kc5trb> AZO for Kalamazoo
[00:35] <KT5TK_QRL> The track might continue after crossing the red line in the east, but this is as far as the predictor can calculate
[00:36] <nigelvh> Your prediction is hitting the edge of the wind data. That's why it's ending near that red line.
[00:36] <NSS-52> what altitude is it at the red line? and what time?
[00:36] <NSS-52> 7 below C inside -25 out
[00:36] <NSS-52> ahhh OK. yeah it's gotta be all different by the time it gets way over there.
[00:37] <nigelvh> The prediction is just based on it hanging around at about 75000ft, the decent won't be predictable until it actually bursts.

[00:53] <ka9szx> So if you are on 144.340 do you have other sites set up to put it to APRS.FI?
[00:53] <NSS-52> some guys here was discussing that and thought of other recomended strings, are you guys still here? Carl is the designer of the payload, any questions about it to him.
[00:53] <carl_> The path I set was suggested by the aprs site.
[00:53] <NSS-52> typo 144.49
[00:54] <NSS-52> UG 144.39
[00:54] <nigelvh> WIDE1-1,WIDE2-1 is generally recommended for cars and other ground based vehicles
[00:54] <NSS-52> there finally got it right.
[00:54] <ka9szx> OK, I am going to see if I can hear it here. So if it is on 144.49 do you have stations to forward the info to APRS.FI sorry if this info is well known but not to me.
[00:55] <NSS-52> 144.39 standard aprs freq
[00:55] <carl_> Yes I tested that here static and it liked the path. Still better that relay
[00:55] <ka9szx> OH, so you are on 144.390. Never mind.
[00:56] <nigelvh> On the ground it's considered a good path, at altitude you'll reach a LOT of stations and create a lot more load on the network as it's digipeating.
[00:56] <carl_> Joe will it make it to sun up? I want to see the solar panel voltage and find out if the rig can run on solar power only.
[00:56] <NSS-52> Yeah I know. But won't get into that argument here.
[00:57] <nigelvh> In any case, we were also talking about the strings. Seems you're using a standard GPGGA string and a separate string for telemetry. Is there a reason for this vs a non-timestamped position string and telemetry in the comment field?
[00:58] <NSS-52> It runs just fine on solar power only. that how I tested it this afternoon with nothing in the box no batts just the solar cells and it fired right up
[00:58] <carl_> The way I send telemetry give me options to change the content.
[00:59] <nigelvh> You can change the content of the comment field of a position packet. It's just text.
[01:01] <nigelvh> Here's an example ":/162804h4741.24N/12219.64W>/A=000269 SATS=9 TEMP=52 RF=228 BATT=14.5"
[01:02] <carl_> That is correct. The aprs control is based on Datatrak by Noqbh.

[01:05] <carl_> how is the valve controlled?
[01:05] <NSS-52> anyone know how to get range distance?
[01:05] <nigelvh> I ended up writing my own APRS code a while ago, so I haven't tried any of that code. In any case, your tracker seems to be working well. I'd just narrow the path a bit for the next flight.
[01:06] WJ9H (a6b50325@gateway/web/freenode/ip. joined #highaltitude.
[01:06] <NSS-52> a string inside the balloon limits the max diameter, choose the diameter the balloon would be at at 75K feet, once balloon expand to that diameter it opens the valve.
[01:07] <carl_> And the switch will report the valve position?
[01:07] kb9zwl (44be861b@gateway/web/freenode/ip. left irc: Quit: Page closed
[01:07] <NSS-52> yup, the switch is a reed switch and magnets on the bottom of the ball the ball is a silocone ball rated to stay soft to -70C
[01:10] <carl_> The ascent seems to be slow which is probably a good thing to limit stress on the balloon
[01:11] <NSS-52> I tried to get it to 300 or so, pressure differential will be nil so wanted it to have plenty of time to vent. it does have a full 2 inch flow opening tho.

[01:19] <SpeedEvil> I measured the heat leak of my 500ml thermos bottle at 3w at 80c delta
[01:19] <NSS-52> If this valve works, we can do a test with ballast to mimic the big honkin balloon use this system to mimic the vented big bag and dump ballast just like that flight ya know a good test.
[01:19] <SpeedEvil> alas not really suitable for pico.
[01:20] <carl_> we flew a thermos bottle on SNOX that housed the batteries. Lost it when the gps failed. Got no usable data on how well it worked.

[02:13] <NSS-52> mmmm, i', back,, corn dogs!
[02:13] <W5VSI> Oh - OK. But if it truely floats, then why does it come down in PA? Or were you just projecting the course?
[02:13] <NSS-52> what altitude is it at when you hit the time limit in PA?
[02:14] <KT5TK_QRL> The red line is just the max longitude the calculator will have data

[02:22] <carl_> perhaps an air density change?
[02:22] <NSS-52> hmmm,, one thing I did not take into account for,,, crap! the balloon isn't really a sphere till it is almost ready to pop. till then the vertical dimention is much longer than the horizontal one. it may already be at the strings length verticvally. did the valve status change?
[02:22] <W5VSI> The gas bubble has cooled & shrunk a bit.
[02:23] <KT5TK_QRL> Not seen VALVE=0 yet

[02:25] <NSS-52> yes it is a momentary switch if valve closes it will show 1 again
[02:25] <KT5TK_QRL> So it might have been at 0 just for a few moments between packets
[02:26] <NSS-52> yup it's has a 2 minute window that it could have one something and we just would not know.
[02:26] <n9qip> I gave up the chase for tonite Joe...LOL

[02:27] <WJ9H> If it stays at this altitude all night, it could intercept the NE blizzard tomorrow...
[02:27] <KT5TK_QRL> descent is way too slow for a burst
[02:27] <NSS-52> agreed.
[02:27] jolo2 (jolo2@ left irc: Read error: Connection reset by peer
[02:28] <W5VSI> Hmmm .. two consecutive alts of 42469 - mebbe a gps 3D error?
[02:28] <KT5TK_QRL> I think the valve worked.
[02:28] <n9qip> Yes..I will resume chase when it comes back around for Orbit 2
[02:28] <NSS-52> just way too soon.
[02:28] <NSS-52> if that is the case
[02:29] <KT5TK_QRL> 42kft may not bee too bad if it stays there
[02:29] <NSS-52> well it's more than 1/2 way across the lake
[02:29] <KT5TK_QRL> that's a cold zone, so if the sun heats it up tomorrow it may be low enough to not burst
[02:30] <KT5TK_QRL> even if the valve freezes or something
[02:30] <W5VSI> Not a great alt for some of the taller civil aviation birds, tho.
[02:30] <NSS-52> if the valve is working it will never burst, just the rot factor, because if the sun comes up it will try to rie again and it would just vent some more to float till sundown.
[02:30] <KT5TK_QRL> well they're 10 kft lower
[02:31] <carl_> going down at 100 ft/min
[02:31] <W5VSI> Some bizjets cruise at 45K'+.
[02:32] <carl_> thankfully lower that normal air traffic this weekend
[02:32] <NSS-52> yeah where it's heading here is none.
[02:34] <carl_> Joe can you still copy direct?
[02:34] <KT5TK_QRL> will be interesting where it travels in the storm

[02:45] <carl_> if it gets below Lexington I may drive after it.
[02:45] <ka9szx> That is quite a prediction change.
[02:45] <KT5TK_QRL> Yes it has completely different parameters now
[02:45] <NSS-52> pretty rural area it looks like
[02:46] <KT5TK_QRL> we're assuming a 0.5 m/s descent
[02:46] <NSS-52> hope it lands in a tree, then it will transmit forever he he he
[02:47] <carl_> I will have to shoot it out of the tree
[02:47] <KT5TK_QRL> The truth is probably between those two predictions
[02:47] <NSS-52> if it lands solar panel up then ntenna will nbe on the ground.
[02:47] <carl_> descent is holding steady at 92 feet per min
[02:48] <NSS-52> over vented I'm assuming
[02:48] <NSS-52> maybe shouldn't have gone for the full flow 2"
[02:49] <carl_> 87.5 feet per min. This may be weather related
[02:49] <NSS-52> I just had a thought Carl, will e mail you about it later or tomorrow.
[02:49] <SpeedEvil> remember, it's 2" at a time when the balloon is several meters in diameter
[02:50] <NSS-52> what are the clouds and water like there at 40K feet in that location?
[02:50] <SpeedEvil> I should work out flow from a 2" orifice under 2mb pressure with helium...
[02:50] <KT5TK_QRL> That's why I'm quite interested in this flight. The optimal venting diameter may be significantly smaller
[02:50] <NSS-52> the neck and the valve is always 2" in diameter
[02:50] <NSS-52> true,
[02:50] <NSS-52> we made land
[02:51] <NSS-52> I was worried about the so low pressure differential, and the cubic footage it would have to vent and all that.
[02:52] <KT5TK_QRL> Only real flight experiments will tell. This is good data to know.
[02:52] <KT5TK_QRL> How heavy was your payload?
[02:53] <KT5TK_QRL> I assume it was a 2000g balloon, not a 200g latex, correct?
[02:54] <ka9szx> Joe, I have been in and out, was this venting a command or just an indication of vent when it did vent?
[02:55] <NSS-52> yeah 2000g totex (Latex) 125 oz of lift at the neck
[02:56] MarkN9XTN (4ba35d2b@gateway/web/freenode/ip. joined #highaltitude.
[02:56] <KT5TK_QRL> Tnx. And what was the actual payload weight?
[02:56] <NSS-52> automatic vent momentary indicator, it could of and must have done it inbetween the measureing of state of the valve.

[03:16] <NSS-52> Interesting info just got.
[03:16] <W5VSI> If the valve popped open to halt ascent, then it oughta be closed again now. So descent is due partly to loss of gas and partly due to cooling & shinking the gas bubble.

[03:18] <NSS-52> OR, according to two pilot friends, they have pilot arning software and righ at the location when she started to come down about 1/2 way across the lake at the upper 30's possible lower 40's there was Icing happening, maybe she just got all ice loaded and the reason for this behaivior?

[03:18] <NSS-52> need an icing moisture ensor Carl! he he he
[03:20] <W5VSI> Icing is most likely to occur at temps near 32F. Much lower and the ice xtals have already formed and just bounce off the envleope.
[03:21] <W5VSI> Anyway, that's wot they taught us in the Navy's aeroplane driving school ...
[03:22] <W5VSI> Did you ascend thru a cloud?
[03:22] <NSS-52> Not locally
[03:23] <NSS-52> they are supposed to send me the warning from their flight program that was warning them about the heavy icing at those altitues.

[03:24] <W5VSI> The only time we ran into balloon icing was when we launched in a steady rain. I was holding the lift line and water was running down my arm! Took 3 lb extra lift compensate.
[03:24] <NSS-52> got it. what altitude is that suppsed to be showing?
[03:25] <NSS-52> I bet thats a LOT of surface area when you think of it.
[03:26] <W5VSI> I think it was the parachute that sucked up a lot of the water. The fast release device failed since it iced up, and the burner didn't work since it wasn't designed to melt a load of ice.
[03:26] <ka9szx> I guess you won't be needing the parachute....
[03:27] <N9UDO> I was told this was 1k to 30k. 50% probability within this range.

[04:29] <NSS-52> gotta say one thing, when it lands if there is anyone around they should find it, because the chute will land nd that should be enough weight to keep the rest airborne and it will be ohhhh 50 feet off the ground or so?
[04:30] <KT5TK_QRL> The chute will probably not be used on this flight :)
[04:30] <ka9szx> Sounds like it is going to go for a drag.
[04:30] <NSS-52> I need a drag right now.
[04:31] <NSS-52> Like wow man....
[04:32] <KT5TK_QRL> the horizontal speed is quite high though
[04:33] <NSS-52> it's been flyin for 5.5 hours right now
[04:33] <NSS-52> wow 200?
[04:33] <NSS-52> gotta see if next is similar
[04:33] <ka9szx> Just got off the phone with Bill WB8ELK. He is coming back from a balloon conference. They are planning on a launch tomorrow, meet around 9 AM CDT with a launch maybe around 10:30 or later in the day. Not sure of the call on the balloon as it is one of the students and he is not sure what he is going to fly as he is a package only on the flight. Probably will drop it in the Atlantic.
[04:34] <ka9szx> In the snowstorm
[04:34] <NSS-52> he should make one like a bouy so when it lands in the ocean it continues on via the glf stream that would be cool.
[04:35] <ka9szx> He felt it would not make the cross at all, probably off the coast of Canada.
[04:35] <NSS-52> batteries are warming up so too voltage came up some.
[04:35] <ka9szx> I think you are going to fall short of Columbus.
[04:36] <NSS-52> hard to say cuz of ground speed.
[04:36] <ka9szx> It will slow down.

[04:57] <NSS-52> last time I looked the bats looked very healthy.
[04:58] <carl_> the batts should last another day at least
[04:58] <NSS-52> they are even maybe 1/2 a volt stronger than what they were at -50C
[04:59] <ka9szx> I would say that is a pretty good prediction sumary, I think maybe a little east of Bellefontaine.
[04:59] <NSS-52> more than that from when i ran it up here. and it's supposed to be very sunny in that area tomorrow.
[04:59] <ka9szx> I think you be lucky if it gets snagged in a tree Joe. My concern is being dragged into a power line.

[05:04] <ka9szx> I think I am going to correct my preditction to North of Bellefontaine more like the predition.
[05:04] <NSS-52> or better yet here we go it lands, and gets stuck a critter ciomes along and cuts the parachute string, and the flight starts all over again.

[10:57] <Adam012> Horizon has had to replace the radio antenna twice now: first one because the coax ground got too knotted, second one because the cramped end was not secure. Nearly done now. Will be running launch checks in 10-15 mins time.

[11:38] <Cillian> number10_M0MDB: They're doing practicals there today, which is part of why I didn't use it

[12:00] <GMT> getting decodes, no lat/long in string
[12:00] <Upu_M0UPU> is that transmitting some sort of NMEA in the string VTG ?
[12:00] <MrCraig> GMT, we think the lassen has lost its lock

[12:05] <gonzo_> just a drifting carrier there at the mo
[12:05] <cstubbs_NSEBASE> got a very strong carrier on 646 but its wobling all over the place :(
[12:05] <cstubbs_NSEBASE> yeah]
[12:05] <gonzo_> drawing nice sine waves
[12:05] <Cillian> Ooh, adam's in france
[12:07] <Hix> just took the AOR apart to replace the battery terminal and i thought i'd buggered it, turns out the payload has gone a bit wrong
[12:07] <cstubbs_NSEBASE> im afraid ive got to go work on my car, but i shall leave the tracker running and check on it every now and again!
[12:07] <MrCraig> Thanks cstubbs
[12:08] <Hix> any news on Horizon?
[12:08] <Hix> and a prediction?
[12:08] <Lunar_Lander> does someone have a frequency maybe?
[12:09] <Hix> oh crap, have they travelled to france to retrieve this?
[12:09] <gonzo_> 434.646
[12:09] <Cillian> Aye
[12:09] <MrCraig> yes Hix
[12:09] <Hix> that's really harsh
[12:09] <gonzo_> fingers crossed for gps getting lock on way down
[12:09] <Cillian> Also to buy me birthday wine and cheese, obv
[12:09] <jcoxon> so has it stopped tx'ing?
[12:09] <Hix> was going to say if its lassen should pick up at lower alt
[12:09] <MrCraig> jcoxon - It's still transmitting, but no gps data
[12:09] <number10_M0MDB> just carrier jcoxon
[12:09] <Hix> fingers crossed
[12:10] <jcoxon> hmmm
[12:10] <jcoxon> so a lassen shouldn't have any issue with altitude
[12:10] <jcoxon> ubloxes if in the wrong mode will break at 12km
[12:10] <MrCraig> looks like lassen lost lock. Payload is 2 years old, might be faults
[12:10] <jcoxon> not 13.9km
[12:10] <Hix> was it tinygps?
[12:11] <Hix> coz some of the samples i've seen have a while gpslock statement
[12:11] <gonzo_> good strength here though. 35-40dB over noise
[12:11] <Hix> so if no lock d=no transmit
[12:11] <jcoxon> i'm wondering if its an power issue
[12:11] <jcoxon> cause there was a string of no GPS data
[12:11] <MrCraig> could cloud cause lock issues?
[12:12] <Hix> not at that alt surely
[12:12] <gonzo_> not very probable
[12:12] <jcoxon> MrCraig, on the ground perhaps but its got such a good view now
[12:12] <cuddykid> it would be interesting to see the code
[12:12] <MrCraig> ok - so all we can do is hope it re-locks
[12:12] <MrCraig> I think I have the code on me actually.
[12:12] <jcoxon> also i'd be interested in regards to which chip and what crystal used
[12:12] <gonzo_> moisture condensing on stuff yes, but again at that alt?
[12:13] <jcoxon> MrCraig, is it an external crystal?
[12:13] <Randomskk> vive la france
[12:13] <MrCraig> no, PIC with its own timing
[12:13] <jcoxon> internal resonator?
[12:13] <MrCraig> Hi Adam, we've lost GPS lock :-/
[12:13] <gonzo_> tty!
[12:13] <MrCraig> yes internal resonator
[12:13] <Randomskk> so i see
[12:13] <jcoxon> temperature
[12:13] <OZ1SKY_Brian> tty?
[12:14] <Habjoe> Hi is Horizon there... are you going to Launch?
[12:14] <MrCraig> PIC16F387 (from memory)
[12:14] <Hix> lloks like rtty coming back
[12:14] <Randomskk> i havent broken the news to the rest of the car yet
[12:14] <OZ1SKY_Brian> yes
[12:14] <jcoxon> MrCraig, its got cold,
[12:14] <Hix> there were 2 lines there
[12:14] <OZ1SKY_Brian> ah just one string
[12:14] <jcoxon> and the resonator would have drifted off a little
[12:14] <jcoxon> so the its not reading hte GPS correctly
[12:14] <MrCraig> So there's a chance of a reset?
[12:14] <MrCraig> hmm
[12:14] <jcoxon> as in if the resonator is off by 1% thats quite a lot off at say 4800baud serial
[12:14] <MrCraig> that's a good point
[12:15] <cuddykid> sounds more like the problem
[12:15] <jcoxon> so if it warms up it'll work again
[12:15] <cuddykid> especially as it was getting a lot colder around 14-20km
[12:15] <jcoxon> now at 13km its at its coldest
[12:15] <jcoxon> exactly
[12:15] <Randomskk> theyre setying raduo up now
[12:15] <MrCraig> that makes a lot of sense.
[12:15] <Randomskk> so will probably all realis no gps lock ny minute
[12:16] <jcoxon> i'd announce on the list that you'd like bearings
[12:16] <Randomskk> good thing we have a yagi huh
[12:16] <jcoxon> the good news is that its still txing
[12:16] <MrCraig> ok, so sitting tight and hoping for warmth and lock
[12:16] <MrCraig> We're going to abandon going further south than leatherhead and get to the top of a hill
[12:16] <OZ1SKY_Brian> there it is again
[12:16] <OZ1SKY_Brian> nice

[14:28] <Hix_> would be good for the thinkpad

[14:30] <Hix_> ok cool
[14:30] <Hix_> found a WWAN card for £20 for Thinkpad
[14:30] <Hix_> so no dongles or wires etc to clutter things
[14:31] <Hix_> and better than phone for tracking on the move

[14:35] <Hix_> yeah, was just thinking of Odiham, but Sat think is pretty much dead there
[14:35] <mfa298> The other option instead of putting a 3G card in your laptop is to get a 3G wifi router - means you can use multiple devices on the one 3g connection

[14:37] <mfa298> more just means more than one device can use the single 3G connection.

[14:37] <cstubbs_NSEBASE> weak though
[14:37] <Hix_> oh ok mfa298
[14:37] <Hix_> same as tehtering from phone then

[14:37] <cstubbs_NSEBASE> a little better on 434.064.90
[14:37] <Hix_> which seems pants normally on orange phone to ipad
[14:38] <mfa298> Hix_: yes same as tethering just with a dedicated box doing it rather than a phone.
[14:38] <Hix_> probably go withthe WWAN card then so the laptop has its own dedicated connection
[14:38] <mfa298> I've had some decent speeds on my Three 3G stick like that (upload is better than my ADSL)

[14:41] <cstubbs_NSEBASE> horizon keeps drifting to almost silent for me every now and again, is that becuase the payload is spinning?
[14:42] <mfa298> Hix_: probably varies, seperate router means you can put the 3g stick in a good location (parcel shelf / by a window) but having it in the laptop makes you more mobile
[14:42] <Cillian> Shouldn't be directional

[15:02] <Spiruel> Is 1.81m3 of gas OK to use in an 800g balloon? The recommended amount is 1.84m3 but that would cost us a lot more just for a tiny 0.03m3 more

[15:41] <Hix_> why are rotators so expensive?
[15:41] <Upu> Adam012 just go to M3 Junction 6 and park up on the A30 and have a listen
[15:41] <mfa298> I'd certainly be tempted to go down Huish Lane a bit to see if you hear anything.
[15:41] <Upu> Adam012 whats your current location ?
[15:42] <Adam012_> We're on Huish Lane, south of the M3. Checking now
[15:42] <Geoff-G8DHE_> The support bearings need to be quite strong! for one thing.

[15:45] <Geoff-G8DHE_> That's why you need strength, if you put the rotater below and have an extra support then it only has to take the weight not the side tresses.

[17:08] <mfa298> lowerstoford: once you've got a decent antenna and radio setup you should be able to track a fair bit of stuff.

[18:12] <mfa298> don't rely on a buzzer to help you locate but it might help once you're close - or it might help draw someone elses attention to it if its close.
[18:12] <spiruel> OK, thanks
[18:13] <mfa298> you also want to consider how much power it needs, although if you're planning on using an rpi you're using a fair bit of power anyway.

[18:14] <spiruel> Is there anything else that we could to measure - for science? :P
[18:14] <spiruel> could try to measure*
[18:15] <mfa298> Id highly recommend starting off with something simple. The more complex you make it the more there is to go wrong.
[18:16] MrCraig (~IceChat9@ joined #highaltitude.
[18:17] <spiruel> Sure, I completely understand that
[18:17] <spiruel> If you're interested, here is the google docs outlining our plans so far: https://docs.google.com/spreadsheet/ccc?key=0AoeBA2fxts5adDRnN3JsUEMtVVNmdS1UZHk3dTNRcmc&usp=sharing
[18:17] <spiruel> If you want to check that out, and see if there's anything blatantly wrong/something to change - please say!
[18:18] <spiruel> It's a very steep learning curve for a student like me who knows practically nothing
[18:19] <W5VSI> The speed of sound varies mainly with air temp. Can measure by building an oscillator from 2 piezo transducers separated by about 1m exposed to ambient air.
[18:21] <mfa298> there's some useful tools linked from ukhas - such as the burst calculator which should give you an idea of how quickly a baloon will rise.
[18:21] <W5VSI> One piezo is a transmitter and the other is a receiver (microphone). Just put a small amplifier between them and record the sound. Freq will vary with air temp.
[18:21] <nigelvh> Another potential measurement option is to use an ultrasonic rangefinder (Must be reasonably accurate), the distance change reported correlates with the change in speed of sound.
[18:21] MrCraig (~IceChat9@ left irc: Ping timeout: 276 seconds
[18:22] <W5VSI> YEah, that would also work if you can put a reflector within the min range of the rangefinder.
[18:22] <Hix_> just thinking if you're doing this on a budget change the £11 temp probe to a £1 tmp36

[18:24] <spiruel> W6VSI: Does the receiver have to be a piezo mic - or can a camera work? Would I measure the frequency recorded from this, or a time lag?
[18:24] <mfa298> what are you thinking of using as a gps tracker

[18:25] <Hix_> worth looking into
[18:25] <spiruel> Hix_: Thanks! Would it connect to a Raspberry Pi? Possible this one?: https://www.sparkfun.com/products/10988
[18:26] <Hix_> don't see why not - though I've not touched Pi
[18:26] <fsphil> does it have to be a Pi? :)
[18:26] <Hix_> thinhk they've got one already
[18:26] <W5VSI> If you have a video camera with a mic, it could record the sound being generated by the 2-piezo oscillator. A 1m distance should yield about 1 KHz.
[18:27] <spiruel> Hix_:Brother is insisting that it needs to be waterproof...
[18:27] <Hix_> though arduino seems "easier" from a beginners point of view
[18:27] <Cillian> Randomskk: oh. hawkward.
[18:27] <mfa298> reading you bit about rpi and temperature I think the previous experience is that if anything the pi could potentially overheat
[18:27] <spiruel> fsphil: My brother is covering that, and he would insist on it :)
[18:27] <Hix_> spiruel: just heatshrinkk it and hot glue it then
[18:27] MrCraig (~IceChat9@ joined #highaltitude.
[18:28] <spiruel> mfa298: Somebody called David Akerman has experienced that - I think he put a simple wire (heatsink?) from the Pi to outside to transfer heat away
[18:28] <nigelvh> Would the frequency shift with the speed of sound? I figured it would just be the propagation speed, not the frequency
[18:29] <nigelvh> So a piezo and a camera wouldn't be able to measure it.
[18:29] <Hix_> spiruel: here's the sensor cheap too

[18:29] <fsphil> if you're launching a Pi, I'd suggest using the new model A
[18:29] <spiruel> Hix_: Brother says the waterproof one includes a guide on how to connect it to the Pi. He says heatshrinking and hot glue probably would work, but may end up even more expensive for the £10 price difference
[18:29] <mfa298> spiruel: that's the one I was thinking of, he's often around on here although I think travelling for his launch tomorrow
[18:30] Babs (027b4ce2@gateway/web/freenode/ip. joined #highaltitude.
[18:30] <Hix_> just hot glue it then
[18:31] <spiruel> Nigelvh: So if we use simple Piezo Buzzer and Mic - we could set the Rasberry Pi would measure the time difference or something?
[18:31] <Hix_> same differnece really
[18:31] <nigelvh> In theory yes, if you have a time reference (An led that turns on at the same time as the piezo that the camera can see.) Syncing the camera and the piezo is the hard part.
[18:32] MrCraig (~IceChat9@ left irc: Ping timeout: 246 seconds
[18:33] <mfa298> you probably want to consider the frame rate of the video and whether that's going to be fast enough to get a suitable measurement.
[18:33] N9UDO (b89ddd94@gateway/web/freenode/ip. left #highaltitude.
[18:34] <nigelvh> Also consider the distance from the piezo to whatever reciever you use. It needs to be far enough away that a measurement is practicable. Like what mfa298 said.
[18:34] <spiruel> nigelvh: Sorry I don't know if I'm understanding correctly. Are you saying that If there is a buzzer that beeps at the sime time as an LED - a camera viewing the LED and recording the sound would work out the time difference, and this could be graphed against altitude?
[18:35] <nigelvh> Yes. Light is *essentially* instant, so you can use that as your time reference. The sound WILL be slower, how much delay between the led and the sound showing up is your time
[18:35] <nigelvh> But if the piezo is too close, the time to travel the distance will be too short to measure with a camera.
[18:36] <Geoff-G8DHE_> Wouldn't you just use the feedback from Mic to Speaker via the sond path to cause the oscillation, as the temp varied the speed of sound varies and hence the frequency ....
[18:36] <nigelvh> No, the frequency wouldn't change, it's the speed of propogation that changes.
[18:37] <Geoff-G8DHE_> quite so the feedback "speed" will vary and hence the frequency
[18:37] <mfa298> I suspect using the video camera might not be feasible as you've got a fairly low sample rate for the video (25fps for PAL)
[18:37] <nigelvh> No, the propogation will be slower, it will take longer to travel a distance, but 1khz is still 1khz
[18:38] <W5VSI> No. You wouldn't wanna use a self-oscillating piezo buzzer. Just two piezo "benders" that operate in around 1 KHz. Use one as a mic and the other as a speaker and put a small audio amp between 'em. That will form an oscillator, just like a PA system with too much mic gain.
[18:39] <nigelvh> W5VSI's method would work. The slower propagation would slow the oscillation.
[18:39] <W5VSI> The 1m distance between the 2 piezos establishes the oscillator freq on the ground.
[18:40] <mfa298> I think I was thinking the same thing as nigelvh which would have difficulties with timing.
[18:40] <W5VSI> We did carry a student payload from Colo State Puelblo that did just that some time ago.
[18:40] <mfa298> but W5VSI's method sounds good.
[18:40] <nigelvh> We've had a student group in in Washington attempt the measurement with a rangefinder.
[18:41] <nigelvh> But it wasn't accurate enough.
[18:41] <W5VSI> We meaning Edge of Space Sciences (www.eoss.org).
[18:42] <spiruel> nigelvh: If I'm wrong please say, and sorry for the rubbish diagram: http://i.imgur.com/frVfdUM.png
[18:42] <W5VSI> The problem with the rangefinder would be in recording its readings. Would have to dedicate a camera to its display, assuming you could find one that works at such low temps.
[18:42] <nigelvh> W5VSI, the rangefinder was a module. You just connected to it with your micro
[18:43] <nigelvh> spiruel, yes, that is what I'm describing, but I believe W5VSI's method would be easier and more accurate.
[18:44] <Geoff-G8DHE_> here you go a bit more complex but the basic idea can be seen also the fact that speed depends on humidity as well. http://www.kyu.edu.tw/93/epaperv7/048.pdf
[18:45] <W5VSI> Spiruel, no that would only record the sound made by the piezo buzzer whose freq is determined by the resonant freq of the brass disk "bender".
[18:45] <nigelvh> Yes, the LED and piezo would be activated at the same time. You wouldn't care about the frequency, you care about the time differential between seeing the led and hearing the piezo
[18:46] <mfa298> W5VSI: I think the idea of the sound+led approach is you can measure the time difference between the light and sound arriving at the camera
[18:46] <nigelvh> W5VSI's method you count the frequency to determine the time differential.
[18:46] <mfa298> but I think for the timing you probably need the buzzer >10m away (not having done any sums to back it up yet)
[18:47] <W5VSI> You'd need to measure that time to well less than 1 msec if the piezo is 1 m away - and that's touch even for a GoPro :=P.
[18:47] <W5VSI> xxx tough.
[18:47] <nigelvh> Yes, the buzzer + led and camera seems inpracticable
[18:48] <nigelvh> I think W5VSI's oscillator system would be most reasonable to build and have the best accuracy, (depending on how accurately you can count frequency)
[18:48] <Hix_> "Launch site is Alston in Cumbria. Flight path will take it SSE approx 50 miles, landing in North Yorkshire. The Yorkshire Immigration Service have been informed."
[18:48] <spiruel> Urgh ;( Ill do for the simple route and just use a barometric pressure sensor board XD
[18:48] <Hix_> Does Yorkshire charge a landing fee, living up to it's stereotype
[18:48] <spiruel> It's annoying how simple science things can become so complicated
[18:49] <nigelvh> That's science. Sometimes things are hard to measure.
[18:49] <Hix_> look at the badgeboard link for the gps tracker

[18:49] <W5VSI> One might make the LED/piezo "clicker" work if there were a lot more than 10m beteen them. But remember the inverse square law. At some point the sound would be
[18:49] <Hix_> there's a wealth of info on that setup on UKHAS
[18:49] <W5VSI> to weak to hear.
[18:50] <spiruel> Well measuring temperature and pressure is easy enough to do with the boards hooked up to a Pi
[18:50] <spiruel> I'm hopefully speaking to Cosmic Ray Specialist from Lancaster Uni in 2 weeks time, for a brief chat about measuring radiation from a weather balloon
[18:51] <spiruel> But that is probably even more complicated? :(
[18:51] <mfa298> The Piezo clicker sounds like something that should be much more compact and still relativly easy to setup.
[18:51] <nigelvh> In theory also doable. The hard part is the high voltage power supply and having it not arc at low air density.
[18:52] <spiruel> Can I do things like put bacteria/small worm in the payload and examine the impact of the hostile environment on them?
[18:53] <spiruel> Or is that worm cruelty... O_O
[18:53] <nigelvh> I'm sure you could. but keep in mind that there's really only two things going on. Really cold, and really little air.
[18:53] HixServer (~Hix@ joined #highaltitude.
[18:53] <nigelvh> So if you want an asphyxiated frozen worm, then sure.
[18:54] <nigelvh> A more interesting project is to try and build a "life support module" that keeps the temperature and pressure at "near ground level"
[18:54] <spiruel> But those two changing factors are fascinating to measure things from - regarding the effects on sound travelling through the medium, the effects of pressure on water, and even cosmic rays at that altitude
[18:55] <spiruel> It's just the cost, weight and feasibility I need to consider. I'm brainstorming for some unique and interesting thing to measure

[18:58] <spiruel> nigelvh: This is what I found on google: http://durpdg.dur.ac.uk/vvc/cosmicrays/images/graph.jpg Shows that there could be at least something interesting to investigate.
[18:59] <spiruel> You can measure differences in radiation by going to the top of blackpool tower
[18:59] <spiruel> So why not 90k feet above the ground?
[19:00] <nigelvh> You certainly can. There WILL be differences in radiation, but keep in mind what TYPES of radiation you're likely to see at a given place.

[19:06] <spiruel> However I am not sure
[19:06] <spiruel> Why do you ask?
[19:07] <Hix_> you've alloted 200grams for it in your spreadsheet - thats heeeeavy
[19:07] <mfa298> I think the consensus is probably that it's worth thinking about early on.
[19:07] <Hix_> sounds like you're using a GPS unit of some sort
[19:07] <nigelvh> spiruel, ideas on light are generally fairly simple. Measuring how much infrared or ultraviolet generally just involves a photodiode and a band pass filter to only pass the light you're interested in.
[19:08] <Hix_> which will fail at altitude
[19:08] <mfa298> a radio tracker potentially a good thing as you can track it live (like the flights earlier) but there's a whole load of legal stuff to comply with.
[19:09] <Hix_> gotta go. see you guys
[19:09] <mfa298> also if you're using a radio tracker it's potentially possible to send back some data live.

[19:12] <mfa298> also seeing your comment about amounts of gas, the more important factor is likely to be how quickly it goes up. On some baloons a slow ascent rate can lead to the balloon floating rather than bursting.
[19:13] <spiruel> mfa298: I think I calculated an ascent rate of roughly 4.1m/s
[19:14] <mfa298> I think the floats have been larger balloons but it's something to keep in mind, I think 4m/s is probably safe, if you're under that it might be more risky.

[20:34] NigeyS (~nigel-win@cpc5-cdif14-2-0-cust507.5-1.cable.virginmedia.com) left irc: Read error: Connection reset by peer
[20:35] <Hix_> sounds about right
[20:35] <Hix_> you'll probably need a separate regulator for it
[20:35] <Hix_> at least capable of 250mA
[20:36] <daveake> No, you don't. The 3V3 regulator has more than 50mA free. A Ublox6 uses around 60mA normally double that when getting a lock. I have had no trouble using it on the Pi.
[20:36] <Hix_> Microship's MCP1700 came highly recommended on here
[20:37] <Hix_> ok corrected
[20:37] <daveake> That said, the best bet is to remove the 3V3 regulator and use a switching regulator
[20:37] <daveake> If you're not using USB, you don't even need the 5V rail.
[20:37] <spiruel> thank you - have to go now. Good Luck with your launch tomorrow - and we hope you don't mind if we send you an email on Monday!
[20:37] <spiruel> bye

[21:17] <mattbrejza> meh http://habitat.habhub.org/habitat/_design/listener_telemetry/_view/time_created_callsign?descending=true&include_docs=true
[21:17] <daveake> bit early imo
[21:18] <mattbrejza> i wanted to see where we drove :(
[21:22] <Upu> Hey Matt
[21:22] <Upu> they were gone before I was going to delete them
[21:22] <mattbrejza> dw they can be retrieved from the db

[21:24] <lz1dev> "Honey, did you let the dog in last night?"
[21:24] <lz1dev> haha
[21:24] <Hix_> what was the reason that caused the wires from an ic not to link to airwires?
[21:24] <Hix_> just done a 50 pin connector to jumpers and none are linked grrr
[21:24] <arko> mornning
[21:24] <Hix_> eagle i mean
[21:25] <Upu> you probably have the snap grid wrong size Hix_
[21:25] <Upu> half grid size
[21:25] <Upu> move the IC and drop it back on the wires
[21:26] <arko> http://i.imgur.com/6O3CVEA.jpg
[21:26] <Hix_> nope 0.1" always told never change in sch
[21:26] <Hix_> ill try moving ic though
[21:27] <Upu> nah
[21:27] <Upu> changed to 0.05"
[21:27] <Upu> alot of parts are 0.05" pitch
[21:27] <Upu> always use imperial units even if running in metric
[21:28] <Upu> i.e use grid sizes of (incoming spam)
[21:28] <Upu> 0.079375
[21:28] <Upu> 0.15875
[21:28] <Upu> 0.3175
[21:28] <Upu> 0.635
[21:28] <Upu> 1.27
[21:28] <Upu> but yeah use 0.05" on the schematic
[21:29] <Hix_> ok move seemed to work, weird though it's still 0.1"
[21:29] <Upu> now move it again
[21:29] <Upu> and delete the spazzy lines that are left over :)
[21:29] <Hix_> thx for metric info though
[21:29] <Hix_> lines move with ic now
[21:29] <Upu> I have those in a notepad
[21:29] <Hix_> and airwires appeared
[21:30] <Upu> want to fire up a join.me and let me have a look ?
[21:30] <Hix_> all good now, eagle is pants
[21:30] <Hix_> i mive
[21:30] <Upu> nps
[21:31] <Upu> it is pants but pants you get to know and love
[21:31] <Hix_> i moved them from the grid back to the same point and it connected
[21:31] <Hix_> I'm considering kicad mitch pushing it heavily
[21:31] <Upu> you might end up with some silly extra wires if you move the ic round now
[21:31] <Hix_> and ive only learned eagle recently so it's not like losing years of experoience
[21:32] <Hix_> Nope, it's all sorted. dunno how it manages it, it's always been 0.1 for schematic
[21:33] <Upu> yeah Mitch is big on Kicad, never used it personally

[22:47] <Hix> Upu, why is it called HAM?

[22:48] <Upu> :)
[22:48] <fspi> it got it wrong
[22:48] <yvette> wish I knew about hams
[22:48] <Hix> ham handed radio operators then
[22:49] <Hix> :)
[22:49] <Upu> so if you know any HAMs in the area they could do with tuning in to 434.200 and decoding the RTTY from that balloon
[22:49] Action: fspi is on a battery powered raspberry pi
[22:49] <fspi> for no apparent reason
[22:49] <Upu> as when that blue circle moves away from the green transmitter tower its out of range (scroll out a bit)
[22:49] <Upu> because of pi
[22:50] <fspi> pi makes it cool
[22:50] <fspi> the battery is 5 times bigger than the pi
[22:50] <Upu> tell you what is cool
[22:50] <Upu> the day/night overlay on the mobile tracker
[22:50] <yvette> so were is everyone from on here thats tracking these balloons
