[02:47] <mrShrimp_> "aprs is ancient?" The website needs to be updated, but the technology and purpose of the system remain relevant.
[02:49] <mrShrimp_> For HAB tracking, however, I like the UKHAS method more.

[06:16] <Darkside> arko: done a payload for one
[06:16] <arko> just wondering
[06:16] <Darkside> not the platform side of it though
[06:16] <arko> perfect
[06:16] <Darkside> i worked on the TOPCAT Payload for UKube-1
[06:16] <arko> could i ask
[06:16] <arko> what was it capable of and what did it cost?
[06:17] <Darkside> the TOPCAT payload was effectively a dual-frequency GPS unit, and a ATMega2560 for data processing, buffering, and sending data to the platform for downlinking
[06:17] <arko> did you use any special hardware like RAD hardened hardware?
[06:17] <Darkside> nope, were were required not to :P
[06:18] <arko> did it work well?
[06:18] <Darkside> it doesn't matter so much in LEO
[06:18] <Darkside> it hasnt been launched yet lol
[06:18] <arko> hahaha
[06:18] <Darkside> but it's passed all the testing, and has been delivered
[06:18] <arko> may i ask how much it cost?
[06:18] <Darkside> in preparation for launch
[06:18] <Darkside> erm
[06:18] <arko> oh awesome!
[06:18] <arko> the payload
[06:18] <arko> if not
[06:18] <arko> dont worry
[06:18] <Darkside> well the dual frequency gps unit was the main expensive bit
[06:18] <Darkside> that was about 4000 quid
[06:18] <arko> ball park is cool
[06:18] <Darkside> the rest of it was crap all
[06:19] <Darkside> like, the BOM for everything *Apart* from the GPS unit would have been around $50
[06:19] <Darkside> perhaps less
[06:19] <Darkside> but thats just our payload
[06:19] <Darkside> theres a *lot* more in the cubesat
[06:19] <arko> your payload was really under 5000quid?
[06:19] <Darkside> also that cost doesn't take into account development time
[06:19] <arko> right
[06:20] <arko> im thinking parts only
[06:20] <Darkside> well it all depends what you want it to do
[06:20] <arko> bingo
[06:20] <Darkside> dont forget this was just one board amongst many
[06:20] <arko> absolutelty
[06:20] <Darkside> all the comms stuff was part of the platform
[06:20] <arko> hmm
[06:20] <Darkside> which we didn't deal with
[06:20] <arko> ohhh
[06:21] <arko> thats why it sounds so cheap
[06:21] <Darkside> i had to implement a spec to talk to the platform and give it data for downlinking
[06:21] <Darkside> yes
[06:21] <arko> whats the platform usually run?

[06:22] <Darkside> TOPCAT is one of 5 (?) other payloads on a 3U cubesat
[06:22] <Darkside> on a ctap net connection atm
[06:22] <Darkside> crap*
[06:22] <Darkside> i think the platform microcontroller is a PIC32
[06:22] <Darkside> though not sure
[06:22] <Darkside> its either that or a MSP430
[06:22] <Darkside> and is likely rad hardened
[06:23] <Darkside> i don't have the info on the platform stuff at hand
[06:24] <arko> thats fine
[06:24] <arko> thanks man
[06:25] <arko> im thinking about joining my school cubesat
[06:25] <arko> just wanted to educate myself before showing up to the club meeting

[11:59] <DanielRichman> daveake: done, thank you :-)
[12:00] <daveake> Cheers :)
[12:00] <navracWork> no - not going to- but a small simple sequence so people with fm receivers can see if they can hear it might be useful when a payload srifts away
[12:01] <navracWork> i can play any tone at the moment - i can also set the rfm frequency to 1hz steps
[12:02] <navracWork> and also play fm at various deviations
[12:02] <Randomskk> shame you can't do two carriers. no chords for you
[12:02] <Randomskk> maybe if you swap between them fast enough....
[12:03] <navracWork> dont think i can manage that on a 4mhz arduino to be honest
[12:04] <jonsowman> I'd think the bottleneck would be how quickly the rfm can retune
[12:07] <navracWork> no - as i'm pulling the crystal directly - the pll seems to keep up quite nicely
[12:07] <jonsowman> ah I see
[12:07] <jonsowman> are you pulling it with a varactor and PWM or..?
[12:08] <navracWork> its more getting the period of the pwm to change on the arduino to generate the different notes for fm
[12:08] <navracWork> varactor and pwm
[12:08] <jonsowman> cool
[12:09] <jonsowman> you should be able to change PWM duty quickly enough
[12:09] <jonsowman> it's just a TOP value for a timer
[12:09] <Randomskk> you should be able to just play an audio stream into the crystal then?
[12:12] <UpuWork> http://imgur.com/a/cNO1I#0
[12:12] <UpuWork> just need pink paint now
[12:12] <navracWork> yep - thats ok for playing notes - but tricky for playing sampled music

[12:21] <daveake> Been doing that for months though ....
[12:21] <cuddykid> haha
[12:22] <cuddykid> need to get a H2 adapter/filler kit as He is too expensive
[12:30] <navrac2> upuwork: post just arrived - thanks
[12:30] <UpuWork> welcome
[12:31] <Laurenceb> is that a soldered lithium AA?
[12:32] <navrac2> one you solder to the ends?

[12:44] <number10> I know the tracking stats are a fun thing, but I was interested to see for XABEN38 that only XABEN 3 trackers stats were recorded and not XABEN 2
[12:45] <daveake> Probably because only xaben3 was associated with that flight
[12:45] <number10> can you associate two trackers with the same flight
[12:45] <daveake> Yup
[12:46] <daveake> You create a payload doc for each one, then you create the flight doc and click an "Add" button to add the first payload doc, then again for the second.
[12:46] <number10> mm - I need to have a look at generating a payload doc again as not done that since ANU1 -- or is it something that the habhub team need to dop
[12:46] <daveake> Or more if you like
[12:46] <number10> chers daveake
[12:47] <number10> +e
[12:47] <daveake> No you can create all the docs yourself. And now it's nice and pretty and more obvious than before
[12:47] <daveake> Also, the payload doc is active as soon as you save it. So if say you've added a field to you telemetry, you can edit the payload doc accordingly, then as soon as you save it you can start uploading
[12:48] <daveake> i.e. as soon as you save the payload doc, your new telenetry should work all the way to the map
[12:48] <daveake> The only bit you can't do is "approve" the *flight* doc
[12:49] RG-lz1dev (~zo@46.47.80.192) joined #highaltitude.
[12:49] <daveake> But you only need that for the actual flight, so that listeners can select the flight (and payload if more than one payload) from the dropdown list in dl-fldigi

[12:49] <number10> thats cool - and the aproval meand that it gets added to fldigi list of flights
[12:49] <daveake> The flight doc also enables the stats to work
[12:49] <daveake> yes
[12:49] <number10> too slow at typing me
[12:50] <daveake> Good job you don't bother fixing your speling mistaes then :D
[12:50] <number10> indeed
[12:50] <number10> you would still be processing last years typos
[12:50] <daveake> lol
[12:50] <number10> I'll get you back ;)
[12:51] <daveake> I know
[12:51] <daveake> I'm just evening things up in advance
[12:51] <radim_OM2AMR> daveake, I hope you will obtain such float as the latest pico, so we can be prepared :-)
[12:52] <radim_OM2AMR> for receiving and decoding
[12:52] <daveake> Well, it's possible, but don't count on it!
[12:52] <costyn> radim_OM2AMR: you are very optimistic :)
[12:53] <radim_OM2AMR> daveake, I trust you ;-)
[12:53] <daveake> I don't trust me
[12:53] <navrac2> I have faith - even with second hand helium
[12:53] <number10> he hasnt purchased a chainsaw yet
[12:53] <radim_OM2AMR> costyn, yeah, but just in case we will be prepared
[12:53] <daveake> :)
[12:54] <radim_OM2AMR> number10, oh so, I read something about trees :-D
[12:54] <daveake> The first rule of UKHAS: Do not mention trees :p
[12:54] <navrac2> or seas
[12:54] <number10> I get fined 10 hab points I suppose
[12:54] <number10> that puts me on -100
[12:55] <radim_OM2AMR> daveake, you was the first ;-)
[12:55] <craag> daveake: What sort of time are you planning to launch?
[12:55] <daveake> Prolly 7pm
[12:55] <daveake> 16 hours battery life
[12:55] <radim_OM2AMR> I was fined with the landing to the trees already, so 10 hab point minus please ;-)
[12:59] <number10> looks like it may be going slightly south radim_OM2AMR http://habhub.org/predict/#!/uuid=47111b4baf49279d88d21244e9f1358e7bb8cb64
[12:59] <gonzo_> at least there are not many trees in the sea
[13:00] <radim_OM2AMR> number10, that direction is good, 400km more and I can catch it at my home ;-)
[13:00] <number10> :)
[13:01] <radim_OM2AMR> maybe we will be surprised like during the last weekend
[13:02] <cuddykid> looks like a good path
[13:03] <number10> I like the new habhub gen payload - I tooks like Randomskk and DanielRichman have done a lot of work :)

[15:28] <russss> imitation is the sincerest form of flattery, and all that
[15:28] <costyn> Randomskk: radio system able to transmit 40 miles? Pffff amateurs
[15:29] <Randomskk> and a "novel" cutdown using nichrome wire
[15:29] <Randomskk> apparently they are also unable to google for people who have done things before
[15:29] <costyn> Randomskk: was just about to say
[15:29] <daveake> the balloon will be released .. at precisely 10:30 AM EST on October 24
[15:29] <daveake> And they've done one before??
[15:29] <Randomskk> http://yaleaerospace.com/horizon/ The craft, now stored by the team for safekeeping, is still one of the most advanced amateur balloons to date, featuring two independent tracking systems, a failsafe aborting mechanism, a camera, and sophisticated software for real-time ground tracking.
[15:29] <costyn> Randomskk: maybe they did and theyr'e claiming it as their idea
[15:29] <costyn> (google things)
[15:30] <Randomskk> of their tracking system: "The system functioned throughout almost all of the flight, a notable achievement."

[15:34] <eroomde> don;t do it!
[15:34] <Randomskk> so it would seem
[15:35] <Randomskk> meh too late, we already are

[15:35] <daveake> "Every situation has been considered and planned for. Our nichrome failsafe system guarantees quick detachment of the payload from the balloon"
[15:35] <Randomskk> just have to do a bigger better one than them
[15:35] <daveake> ho hum
[15:35] <costyn> daveake: hehehe
[15:35] <daveake> "Every" and "guaranteed" eh?
[15:36] <Randomskk> I am highly suspect :
[15:36] <Randomskk> :P *
[15:36] <BrainDamage> ofc, it's also novel that nobody tought about it before
[15:36] <costyn> these pages were written like they were meant to attract sponsors
[15:36] <BrainDamage> or done
[15:36] <fsphil> some people are allergic to google
[15:36] <Randomskk> five minutes ago they were 30 seconds away from launch
[15:36] <Randomskk> wonder what happened
[15:36] <costyn> Randomskk: ish time
[15:36] <eroomde> precisely 10.30
[15:36] <Randomskk> fsphil: presumably they didn't even think to see if it was done before. perhaps it was obviously novel
[15:36] <daveake> They've discovered ISH or Bill Standard Time?
[15:37] <daveake> Tsk. Students. :)
[15:37] <eroomde> "the balloon will be released from Hubbard Park, Meriden, CT at precisely 10:30 AM EST on October 24. "

[15:38] <costyn> navracWork: MADNESS
[15:38] <navracWork> it cant be done]
[15:38] <fsphil> they're risking us all!

[15:39] <Randomskk> the website has absolutely no specific details
[15:39] <craag> Ah, for their 40-mile radio link...
[15:39] <Randomskk> just a very very vague specification
[15:39] <costyn> daveake: rage inducing?
[15:39] <daveake> "The counter is paused at T - 5 minutes"
[15:40] <daveake> NASA could learn from them I'm sure

[15:42] <costyn> ooh 304m
[15:43] <costyn> crappy tracker is crappy
[15:43] <craag> Their site's broken for me. Capacity problems apparently.

[15:47] <daveake> Yes, that top one
[15:48] <costyn> daveake: ah had to clikc the 'all' button
[15:48] <daveake> ah
[15:48] <daveake> Average now is 0.72m/s
[15:48] <Randomskk> that's not going to pop for a loooong time
[15:49] <craag> Their tracker is making 5 requests a second to php scripts, about 3KB per second, per person.
[15:49] <fsphil> if they're using a phone, how are they planning to command the cut-down?
[15:49] <daveake> 0.7m/s is pretty much what I'll be aiming at this evening :D
[15:49] <fsphil> I can't speak about inefficient php code :)
[15:50] <daveake> lol
[15:52] <navracWork> shall we place bets on when their altitude cuts out?
[15:53] <fsphil> 2km
[15:53] <radim_OM2AMR> it will be another floater probably ;-)
[15:54] <Randomskk> I don't think they actually have radio uplink, just time based cutdown?
[15:54] <Randomskk> who knows.
[15:54] <Randomskk> it does seem to be tragically bad
[15:54] <Randomskk> you almost expect better of yale
[15:54] <Randomskk> I bet MIT wouldn't stand for this
[15:54] <navracWork> its going to be a toss up whether the internal temperature rising will kill it first.
[15:54] <mattbrejza> so how long does an average go-pros battery last?
[15:54] <navracWork> if its 31 degees at this level, when the air gets sucked out...
[15:55] <fsphil> did they add heating?
[15:55] <fsphil> I can't identify much in the picture of the payload
[15:55] <radim_OM2AMR> fsphil, yes a lot of batteries and computers ;-)
[15:55] <daveake> Well it's either going up very slowly, or the altitude report is wrong. Either way I hope it's a time-based cutdown not altitude.
[15:56] <mattbrejza> tweet them tocome on here...
[15:57] <navracWork> didnt mention it - but im not convinced about the temp readings at all
[15:57] <radim_OM2AMR> oh, temperature is rising, tropopause achieved ? :-)
[15:57] <navracWork> 12 degrees drop in 800m?
[15:57] <daveake> no chance
[15:57] <daveake> maybe a hole letting some wind in
[15:58] <navracWork> maybe the altitude is out by a factor of 10?
[15:59] <radim_OM2AMR> oh, I thing, it's ext temp variable overflow, probably it should have minus sign now...
[15:59] <daveake> Erm, I think the alt is a bit random. Not 100% sure but I thought I saw it jump 850m to 13xxm to 1700m within a minute
[15:59] <fsphil> at least they are nowhere near the meridian. although with that ascent rate...
[16:00] <daveake> OK, I just saw 2300m @ 15:52 and 2700m : 15:58
[16:00] <gonzo_> it's really far more sensible to send the raw values and do the processing on the ground
[16:00] <navracWork> is that when the gps jumped a lot to the east as well though?
[16:00] <daveake> Good job that altitude plot is blank
[16:01] <daveake> Dunno - wasn't watching that
[16:01] <kokey> is there something up in the air at the moment?
[16:01] <radim_OM2AMR> http://yaleaerospace.com/live-4/
[16:01] <daveake> OK, I think the "time since launch" is just a local thing on their web server, and the altitude is getting delayed by random times
[16:02] <kokey> what's the latest theories on the XABEN3 string errors?
[16:02] <costyn> my guess is they're as confused as we are, furiously digging through their code trying to figure things out
[16:02] <Randomskk> costyn: you mean writing up a process to investigate writing a report to suggest modifying the codebase to reduce the altitude inaccuracies?
[16:02] <navracWork> i like the way the gps position jumps 1km from side to side on alternate updates
[16:03] <daveake> If the current altitude is correct, that's around 2.5m/s
[16:03] <craag> navracWork: That is hilarious.
[16:03] <costyn> Randomskk: hehe something like that
[16:04] <navracWork> Is this yale as in the real yale? or like anglia ruskin cambridge?
[16:04] <kokey> Hartford and Worcesster, hah, they should learn to spell
[16:04] <eroomde> the real thing i think

[16:16] <daveake> Julie already found some maple syrup flavoured yoghurt
[16:16] <fsphil> bacon butty with maple syrup?
[16:16] <daveake> We had waffles w/ syrup for brekkie most days
[16:16] <fsphil> that sounds nice
[16:17] <fsphil> pancakes and syrup is nice
[16:17] <daveake> yup
[16:17] <number10> I got some funy looks there for skipping the maple syrup and putting a little salt on french toast
[16:17] <daveake> urgh
[16:17] <fsphil> salt?
[16:17] Action: fsphil gives number10 a funy look
[16:17] <number10> lol I was expecting it
[16:17] <daveake> Still 3179m
[16:18] <number10> its like would you put salt on scrambled egg on toast?
[16:18] <daveake> Such a shame the altitude plot is blank
[16:18] <eroomde> ^
[16:18] <fsphil> I don't put salt on anything
[16:18] <daveake> ditto
[16:18] <daveake> Never did, but now it's for medical reasons anyway
[16:18] <navracWork> ok the picture of the payload has the if found telephone number on it - shall we ring it and claim we've found it?

[16:19] <daveake> Fair point
[16:20] <number10> what does she mean whatch it, whatch it - about that fried cheescake
[16:20] <daveake> Well, they seem to have achieved a float at 3179m :p
[16:20] <navracWork> well we could offer to put the weight and lift into the cusf calculator and tell them where it landed
[16:21] <navracWork> or at least tweet them a link to the page with the message - you might need this....
[16:22] <navracWork> right time to go home
[16:22] <radim_OM2AMR> 3179m, their tracker is using GSM probably

[17:25] <adamo> hi
[17:26] <x-f> hi, adamo
[17:27] <adamo> does anyone have a piece of sample code i can quickly use to test my ublox gps module can parse its strings via RTTY with a Radiometrix?
[17:30] daveake (~daveake@daveake.plus.com) left irc: Quit: Leaving
[17:31] <x-f> you want to send NMEA sentences from uBlox with NTX2?
[17:31] <adamo> Yes! :)
[17:32] <x-f> there's a sample code for RTTY on UKHAS wiki
[17:32] <adamo> and i'd be really grateful for some code that can do that for me so i know it all works
[17:32] <Upu> and for the GPS
[17:32] <adamo> yes, i can send strings of text
[17:32] <Upu> and then play with the TinyGPS library thats built into Arduino
[17:32] <adamo> but i'm interested to see how i can implement the gps into the system now
[17:32] <adamo> hi upu
[17:32] <Upu> and with all three you should be able to cobble something together
[17:32] <Upu> hi
[17:32] <adamo> :)
[17:32] <Upu> what your asking for isn't a "quick test" its working code
[17:32] <Upu> and most people won't give you that
[17:33] <adamo> ah
[17:33] <adamo> wasnt sure how else i could test it haha
[17:33] <adamo> TinyGPS..
[17:33] <Upu> well if you can TX the radio is working
[17:33] <Upu> if you can get strings in using the demo code the GPS is working
[17:33] <Upu> the next step is putting it all together
[17:33] <Upu> and thats ADAMO-1's code
[17:33] <adamo> yes, but how to see if the gps can pass on the strings to the transmitter
[17:33] <Upu> yours
[17:33] <adamo> ;)
[17:33] <Upu> :)
[17:34] <Upu> well yes it can but you have to work that bit out
[17:34] <adamo> oh lol
[17:34] <Upu> but really its not hughly complex
[17:34] <Upu> hugely
[17:34] <Upu> ignore the transmitter
[17:34] <adamo> so this tinygps can help me glue the pieces together?
[17:34] <Upu> play with TinyGPS library
[17:34] <adamo> ok
[17:34] <Upu> there are examples
[17:34] <Upu> but
[17:34] <Upu> understand what you're doing
[17:35] <adamo> surely i need to be considering the transmitter?
[17:35] <Upu> don't just cobble peoples code together or you'll end up with an unworkable mess that no one can help with
[17:35] <adamo> when i look at code, i can pick out most of the methods and variables etc, but its learning the new things
[17:35] <adamo> ok
[17:35] <Upu> adamo sure later, if you can output a string to serial like $$ADAMO,1,12:00:00...etc you can transmit it
[17:35] <Upu> so don't complicate matters just do it all to serial for the moment
[17:36] <Upu> keep it simple, break it down in to small chunks, understand them and then slowly add each bit together
[17:36] <Upu> and lots of testing
[17:36] <adamo> ok
[17:36] <adamo> ill be having a GPRS GPS tracker as a backup, but because i live in a rural area the amateur radio should be more reliable
[17:37] <Upu> indeed
[17:37] <Upu> but again
[17:37] <Upu> one thing at once
[17:38] <adamo> ok
[17:39] <Upu> right I best go cook

[18:56] <craag> AA?
[18:56] <number10_M0MDB> thats not bad
[18:56] <daveake> 4 AAAs

[19:26] <costyn> i have some simple code that is producing strange results, I think it's a buffer overflow somehow but I don't see where it's going wrong: http://pastebin.com/nWPBPfBx the output is at the bottom

[19:59] <mrShrimp_> Hey Upu!
[19:59] <Upu> evening mrShrimp_
[19:59] <mrShrimp_> I don't know if you got my previous messages, but I was wondering about the ordering options for the 433 MHz filter/amp...
[20:00] <Upu> sorry my PC died
[20:00] <Upu> PM me
[20:00] <mrShrimp_> no problem
[20:00] <mrShrimp_> I'll just ask you here, it isn't much of a question :p
[20:00] <Upu> oh ok
[20:00] <Upu> shoot
[20:01] <mrShrimp_> I was wondering which option for powering the module is most reliabe/superior to the others?
[20:01] <Upu> I don't think any is better than any other
[20:01] <Upu> just depends how you wish to supply the power
[20:01] <Upu> in short
[20:01] <mrShrimp_> Oh ok
[20:01] <Upu> option 1 = powering from the USB's 5V
[20:02] <Upu> option 2 = powering from an external > 5V power, i.e battery or external PSU
[20:02] <Upu> option 3= bias-t powering from say the fun cube dongle
[20:02] <Upu> option 4 = you're bias-t provides > 5V
[20:02] <mrShrimp_> right
[20:03] <mrShrimp_> I think on your order page, option 2 is the bias-5 power from the fun cube.
[20:03] <Upu> checking
[20:03] <mrShrimp_> "2/ 3-5V via bias-T - suitable if your reciever can provide bias-T i.e Funcube Dongle"

[20:04] <Upu> ah yes sorry
[20:04] <mrShrimp_> oh np
[20:04] <mrShrimp_> I think option 1 would be the easiest then.
[20:04] <Upu> most people go for that
[20:04] <Upu> are you getting a dongle too ?
[20:05] <mrShrimp_> Yes, this one: http://ava.upuaut.net/store/index.php?route=product/product&path=71_63&product_id=70
[20:05] <Upu> ok https://dl.dropbox.com/u/63720513/Images/HAB/HAB%20Filter/IMG_0692.JPG
[20:05] <Upu> is how you get the 5V
[20:05] <mrShrimp_> Ok
[20:05] <mrShrimp_> that explains the extra wires in the tutorial picture.
[20:05] <Upu> in fact if you want I can wire it for you if you buy both and I'll put a plug on there
[20:06] <Upu> you'll need to get an SMA to SMA joiner to link the two
[20:06] <mrShrimp_> barrel connecter
[20:06] <mrShrimp_> I already ordered it on amazon
[20:06] <daveake> spacenear seems to be running about 3 minutes behind the actual telemetry

[20:08] <Upu> I should be able to ship tomorrow mrShrimp_
[20:09] <Upu> bear in mind normal airmail to the US is SLOW

[20:40] <daveake> I'm guessing that the northword wind is hitting the eastward wind, and where the two meet the air is being pushed up
[20:40] <daveake> and Buzz is going up with it
[20:41] <navrac> and down again
[20:41] <daveake> yup
[20:41] <daveake> now if it starts heading east maybe that's what happened

[20:42] <navrac> oh good - I'd like it to get a bit stronger above the local qrm - theres an annoying transmission right on frequency
[20:42] <Lunar_Lander__> :(
[20:42] <navrac> nah it would fall faster
[20:42] <daveake> I think so too
[20:44] <navrac> or it could have been pushed up by air currents till it got high enough to create a leak

[20:45] <daveake> phew
[20:46] <KT5TK_QRL> If the temperature it shows is correct, then it's pretty warm up there. Is the Sun shining?
[20:46] <daveake> That's internal, and there's a linear regulator dissipating heat
[20:46] <jonsowman> KT5TK_QRL: the sun is most certainly not shining, least of all because it's nighttime :)
[20:46] <daveake> 5.83V --> 3.3V @ 70mA or so
[20:46] <jonsowman> also because it's the UK

[20:50] <LazyL_M0LEP> Hiya Mike
[20:51] <LazyL_M0LEP> (...or was that just an auto-re-login...)
[20:51] <daveake> It is...direction was 355-ish (-5) and now is +10
[20:52] <navrac> I think it realised it was going to be in birmingham if it didnt change course
[20:52] <Upu> lol
[20:52] <daveake> Don't blame it
[20:53] <LazyL_M0LEP> There was a mouse running around at the Bromley club meet last week ;)
[20:53] <daveake> Brum sucks but Buzz has more power
[20:53] <navrac> why did you put the 4AA's in series rather than in // dave?
[20:53] <LazyL_M0LEP> Going to Coventry instead...

[20:54] <daveake> navrac it's a linear reg so needs at least 3 in series
[20:54] <daveake> And it's AAAs
[20:54] <navrac> i did wonder - i ssumed it was a step up being a pico
[20:55] <daveake> The 4th one was basically to weigh it down a bit :)
[20:55] <daveake> Will give a bit more life but not a lot

[21:30] <eroomde> that's a git question rather that a github question Lunar_Lander_
[21:30] <Laurenceb_> maybe its condensation
[21:31] <eroomde> if you haven't done a git tutorial, I recommend it. It will make everything make more sense

[22:14] <cuddykid> yep
[22:14] <cuddykid> coming down quite fast now
[22:14] <daveake> it had 9g free lift, so anything more than 9g water and it'll come down. However I think it's burst
[22:15] <Laurenceb_> hmm im not so sure
[22:15] <daveake> i did think it had burst before it levelled out earlier, mind
[22:15] <jcoxon> i'm not sure its burst
[22:15] <jcoxon> it would be coming donw faster
[22:16] <Laurenceb_> yeah
[22:16] <Laurenceb_> and not levelling off
[22:16] <daveake> true
[22:16] <Laurenceb_> like the wind shook the water off

[22:50] Action: heathkid still has a lot to learn
[22:50] <jcoxon> heathkid, the first rule of ballooning...
[22:50] <jcoxon> never rush
[22:50] <Randomskk> I thought it was "check the wiki"?
[22:50] <jcoxon> gets broken all the time
[22:51] <fsphil> hah, it's going up again
[22:51] <Laurenceb_> jcoxon: you were right
[22:51] <heathkid> there is a wiki?
[22:52] <daveake> jcoxon is always right
[22:52] <LazyL_M0LEP> Heh! Of course! --> http://ukhas.org.uk/
[22:53] <chris_99> is down
[22:53] <LazyL_M0LEP> ...but you _knew_ that. ;)
[22:53] <chris_99> oh it's up now

[23:00] <KT5TK_QRL> Wow picobuzz skyrocketing back close to 3km

[23:01] <KT5TK_QRL> was a short deprssion
[23:01] <KT5TK_QRL> depression
[23:03] <jcoxon> KT5TK_QRL, ever tempted to launch a ukhas style pico?

[23:03] <KT5TK_QRL> There's not much difference really

[23:04] <KT5TK_QRL> Pecan can also do 70cm
[23:04] <KT5TK_QRL> I just don't have many listeners here at that freq
[23:05] daveake (~daveake@daveake.plus.com) joined #highaltitude.
[23:06] <jcoxon> if you transmit it they will listen :-)
[23:06] <KT5TK_QRL> Well I tried that with a PSK beacon this August. Tere were only 2 listeners. NASA and me
[23:07] <Lunar_Lander> wb daveake
[23:07] <KT5TK_QRL> I mean the NASA Ham club station W5RRR
[23:09] <jcoxon> oh well
[23:09] <jcoxon> listening stations are much more fun then aprs
[23:10] <KT5TK_QRL> I'm sure ssb/rtty is more sensitive
[23:11] <KT5TK_QRL> However the APRS digis/igates are always there and the frequency drift is not difficult at FM
[23:12] <jcoxon> sure
[23:12] <jcoxon> i guess you start with a few and it grows
[23:12] <jcoxon> buzz ain't going to give up yet
[23:13] <KT5TK_QRL> When I'll ever be able to launch a transatlantic floater I'll make sure it'll switch to 70cm RTTY in software if it comes close to the UK
[23:14] <jcoxon> hehe
[23:14] <jcoxon> we can do HF

[23:14] <KT5TK_QRL> Yep, that was the 14MHz PSK experiment for :)
[23:15] <jcoxon> right bed for me
[23:15] <jcoxon> night all
[23:15] <jcoxon> good luck picobuzz

[23:18] <KT5TK_QRL> picobuzz is getting picked up from the North-West Wind. I think what we see is turbulence of shearing air masses
[23:18] <daveake> I think so. The very first blip was at the point where the northbound wind started to hit the eastbound
[23:19] <daveake> It has a pressure sensor onboard but I didn't bother polling it :(
[23:20] <Laurenceb_> doh
[23:20] Dan-K2VOL1 (Dan-K2VOL@rrcs-24-103-47-219.nyc.biz.rr.com) left #highaltitude.
[23:21] <daveake> The code's all in there I just didn't enable it this time
[23:23] <Lunar_Lander> why?
[23:24] <daveake> Because I didn't expect anything interesting to happen
[23:24] <KT5TK_QRL> Note that the temperature is still very warm. From the altitude and the temp you could calculate the pressure. How big is the difference between inside and outside temperature?
[23:24] <daveake> That's the internal temperature
[23:25] <daveake> Don't have an external sensor
[23:26] <KT5TK_QRL> I don't expect the difference to be very big after 5 h flight
[23:27] <KT5TK_QRL> It's definitely far above freezing point (which is good)
[23:28] <Lunar_Lander> btw temperature difference is not warm
[23:28] <Lunar_Lander> you can only say it is big
[23:28] <KT5TK_QRL> Comparing to fsphil's flight last weekend where the temperature was much lower
[23:29] <fsphil> I think that was jcoxon's flight
[23:29] <KT5TK_QRL> I didn't say dT was warm?

[23:29] <KT5TK_QRL> ah, sorry. it was PICO
[23:30] <fsphil> I've got a pico coming up soon though
[23:31] <KT5TK_QRL> looking forward to it
[23:33] <Lunar_Lander> sorry, KT5TK I misread
[23:34] <Lunar_Lander> still a temperature can be high or low not warm or cold
[23:34] <Lunar_Lander> :)
[23:34] <Lunar_Lander> (sorry for being in Sheldon Cooper mode)
[23:35] <KT5TK_QRL> OK, I'll remember that. Physical chemistry was one of my worst classes at the University. I didn't expect that I'll need it for HABing....
[23:36] <Lunar_Lander> no problem
[23:36] <daveake> I was supposed to be getting some sleep tonight :(
[23:37] <KT5TK_QRL> No chance for bed time
[23:37] <daveake> Need to appear bright and awake for the cameras in the morning :D
[23:37] <KT5TK_QRL> I can suggest some plastic surgeons here in Houston ;)
[23:38] <daveake> There's a slight lack of time considering I have to be back here in 8 hours ...

[23:44] <daveake> No flights now till 6:15 :)
[23:47] <Laurenceb_> battery voltage is holding well
[23:47] <Laurenceb_> whats the expecte dlife?
[23:48] <daveake> Well, I've had (IIRC) 16 hours out of 3 AAAs in the freezer, with that type of tracker. This is 4 AAAs and won't get that cold, so 17 hours or so.
[23:48] <daveake> Which takes it to midday

[23:53] <Lunar_Lander> daveake, I am so happy right now
[23:54] <daveake> OK, I'll bite. Why are you so happy?
[23:55] <Lunar_Lander> because I think I mastered that coding stuff now :)
[23:56] <daveake> "mastered"? Shit, I've been doing it for 35 years and I'm nowhere near that :D
[23:56] <daveake> Anyway glad you're on top of it :)
[23:56] <Lunar_Lander> sorry, not mastered
[23:56] <Lunar_Lander> hmm
[23:56] <Lunar_Lander> understood it
[23:57] <Lunar_Lander> :)
[23:57] <daveake> cool
[23:58] <Lunar_Lander> :)
[23:59] <Lunar_Lander> upu said earlier that he almost tipped over when I said that flight is now in sight
[23:59] <daveake> I bet
[23:59] <daveake> Don't rush into it, but it will be great when you do finally take that step
