[02:36] <Darkside> it did a felix
[02:36] <Darkside> i.e. delayed the launch

[06:06] <Darkside> how did that happen
[06:06] <Darkside> did th camera fall out of his eye or something?
[06:06] <daveake> He turned round
[06:06] <daveake> The capsule thing had a smooth glossy surface
[06:06] <daveake> laminated sheet of paper
[06:07] <daveake> so that's a reflection
[06:07] <Darkside> ahh ok
[06:07] <daveake> I went a bit low on the cutdown power
[06:07] <Darkside> ahh
[06:07] <Darkside> you use a resistor?
[06:08] <Darkside> or nichrome
[06:08] <daveake> So having another go today with moar powwwer
[06:08] <daveake> Yes
[06:08] <Darkside> i just use nichrome across 2x AAs
[06:08] <Darkside> works like a charm
[06:08] <daveake> worked before but I was worried about weight and only had AAAs in there
[06:08] <Darkside> the AAs internally limit
[06:08] <daveake> yeah it'll work this time :)
[06:08] <Darkside> cool :-)
[06:08] <Darkside> looking forward to it
[06:08] <daveake> should be fun

[06:27] <daveake> dunno but looks like a balloon to me
[06:27] <Darkside> heh
[06:27] <Darkside> did you launch 2 balloons at the same time?
[06:27] <daveake> nope!
[06:27] <Darkside> theres no other way you'd get that close
[06:27] <daveake> I've no idea where the nearest met office launch site is
[06:27] <Darkside> we saw how hard it was to see each others balloons from our launch
[06:28] <daveake> true

[07:36] <Darkside> Bo_DK: probably easier to do the solar stuff separately
[07:36] <Upu> E-bay
[07:36] <Darkside> buy an existing solar charge circuit
[07:36] <Upu> or daveake :)
[07:36] <Darkside> and just assume theres 12v available

[07:37] <Darkside> balls of...
[07:37] <Darkside> foam

[07:59] <Tom____> Hi, apologies for a newbie question and a long question! I'm researching launching a high altitude balloon for the first time, and I specifically looking into receivers. As this is a first project, my budget is low but I also want to get equipment that works. It seems using USB-TV-Dongles aren't great/mixed results but the FUNcube Dongle looks ok. Is that my best bet for the £100-£150 price bracket?

[09:05] <G0TDJ_Steve> Cool
[09:05] Action: cm13g09 returns to IRC
[09:08] <G0MJW-PC> It does seem difficult. I can't understand what is is showing me at the moment. It looks like it has not set the right frequency on the dongle
[09:09] <Geoff-G8DHE-M> You have the MAIN tuning scale with big blue arrows each side that show the tuning range
[09:09] <Geoff-G8DHE-M> then the waterfall for that spectrum
[09:09] <craag> welcome back cm13g09 !
[09:09] <Geoff-G8DHE-M> then the spectrum levels above
[09:09] <G0MJW-PC> Yes but it is only sampling at 45kHz and it seems to be tuned to medium wave and not 434MHz as claimed
[09:10] <Geoff-G8DHE-M> then You have VFO's, which can be set to tune part of the overall range
[09:10] <Geoff-G8DHE-M> Click the VFO Tuning buttonabove the main spectrum
[09:10] <Geoff-G8DHE-M> a panel appears probaly on the left
[09:10] <G0MJW-PC> Right - that's better. Radio setup was ampling 44kHz. Pro Plus does not do that.
[09:11] <Geoff-G8DHE-M> select the Direct Tab and enter the details you want
[09:11] <Geoff-G8DHE-M> You can then save the settings to the Bands Tab for the future
[09:12] <Geoff-G8DHE-M> Until you click in the spectrum/waterfall area you won't have selected a new frequency
[09:12] <G0MJW-PC> Yes, so now I have VFO A on Left and B on right

[09:14] <Geoff-G8DHE-M> You can move all the Panels around, just watch the little placment Icons that appear above background panels to enable Stacking or posiioning

[09:15] <Geoff-G8DHE-M> Once you have a freq. set then if the Tx is stable (LeoB) you canmove onto another VFO ;-)
[09:15] <mfa298> cm13g09: was good to catch up.
[09:15] <G0MJW-PC> Luckily, I have two monotors here. I was thinking about getting 3.
[09:16] <Geoff-G8DHE-M> It really helps by the time you open all the dl-fldigi's!
[09:16] <G0MJW-PC> Yes, now how to get one on left and one on right...hmm
[09:16] Action: jcoxon is compiliing the arm-gcc toolchain
[09:16] <Geoff-G8DHE-M> Right BBL for the launches!
[09:17] <mfa298> I'm not sure dl-fldigi can listen on the right channel, that's where virtual audio cable gets useful. lots of virtual sound cards to use
[09:17] <G0MJW-PC> Geoff-G8DHE, Is the FCD normal or reversed IQ in SDR radio?
[09:17] <mfa298> G0MJW-PC: my Pro+ seems to be normal mode, it seems like it's only sdr# you need to hit the swap button
[09:18] <G0MJW-PC> Thanks.
[09:18] <Geoff-G8DHE-M> Don't use an FCD just RTL dongles so not sure its straight for the Dongles
[09:18] <G0MJW-PC> I am struggling getting DL-FLGIGI to work on left and right seperately

[09:36] <G0MJW-PC> I gave up on getting GRC to work with the pro plus, needed 3.7, but its so different it breaks to much from 3.6

[09:59] <G0MJW-PC> I would knock something up in c++ but I don't have the skill or patience
[09:59] <mfa298> I'd really like it if dl-fldigi could use multiple audio inputs on the same device, I've got a 6 channel audio interface which would be nice to use with multiple real radios

[11:54] <Bo_DK> Is there any benefit to mounting backup battery on ublox??
[11:55] <Willdude123> Who's the guy on the left?
[11:55] <Willdude123> Bo_DK, it keeps lock if the power source goes down
[11:55] <Bo_DK> ok....
[11:55] <craag_web> Bo_DK: Only if you're powering the unit off and on.
[11:55] <ed__> Willdude123, nope
[11:55] <ed__> it doesn;t do that
[11:55] <ed__> it keeps the ram contents hot
[11:55] <Bo_DK> so in my case a big no since tracker will not work without power anyway
[11:55] <ed__> so it doesn't have to redownload the entire ephemeris again when the main power comes back
[11:55] <Willdude123> ed__, Oh yeah
[11:56] <ed__> provided that the empheris is still fresh, that saves the few minutes of waiting for lock
[11:56] <Willdude123> Who is everyone I can see on the stream?

[12:58] <Bo_DK> not stupid....
[12:58] <Bo_DK> me just not that good
[12:58] <Randomskk> the answer is to avoid the eagle autorouter
[12:58] <Randomskk> you are better than it
[12:58] <ibanezmatt13> Lunar_LanderU: Very well, 35.5km and recovered in wheat field. NORB had some issues transmitting wise but only above 25km. I've fixed that now I think
[12:58] <Bo_DK> Randomskk you have hight thoughts about me them

[15:14] <mattbrejza> chrisg7ogx: another example http://i.imgur.com/i2N8Z4R.gif
[15:14] <LeoBodnar> It's using time the report has been received by the server instead of timestamp in the report which screws up plots if data is delayed / mixedup

[15:15] <cm13g09> the random noise around 434.000
[15:15] <Darkside> unless you calibrate it with a known signal generator, you wont easilty be able to know what the values you're seeing mean
[15:15] <cm13g09> yeah
[15:16] <Darkside> thats local LIPD stuff
[15:16] <Darkside> well, what we call LIPD's in australia
[15:16] <Darkside> 434mhz ism band stuff

[15:23] <mattbrejza> so actualy encode as video rather than a serie sof images
[15:23] <daveake_> yes
[15:23] <mikestir> but the problem with sending P frames is that if any of the data is lost you lose all the rest until the next I frame

[18:24] <LeoBodnar> Laurenceb_ are you around?
[18:24] <Laurenceb_> yup
[18:24] <LeoBodnar> That was quick :)
[18:25] <LeoBodnar> Going back to our yesterday's discussion I think I can use a 1W heater inside the balloon which will inject 220J of energy in the matter of 3-4 minutes.
[18:25] <Laurenceb_> interesting
[18:26] <Laurenceb_> but im now thinking that increasing free lift to 3grams might be way easier
[18:26] <LeoBodnar> However I am not sure how to calculate heat loss through the envelope into the environment. Any ideas?
[18:26] <Laurenceb_> id just work out the descent rate and subcooling
[18:26] <Laurenceb_> so it was about -1m/s and -10C ?
[18:27] <LeoBodnar> It gets a bit dangerously close to rupturing during direct sunshine periods
[18:27] <Laurenceb_> true
[18:27] <LeoBodnar> Yes roughly so
[18:27] <Laurenceb_> so adiabatic lapse rate is about 10C/Km
[18:27] <Laurenceb_> so 1Km/(1m/s)=1000s
[18:28] <Laurenceb_> thats the thermal equilibium period
[18:28] <LeoBodnar> I have arrived at necessity to heat up inside gas to extra 7-8 degrees to arrest the descent
[18:28] g8kbz (50b1d1df@gateway/web/freenode/ip.80.177.209.223) left irc: Quit: Page closed
[18:28] <Laurenceb_> ok
[18:28] <Laurenceb_> so if you took 1000s you would achieve approx nothing
[18:29] <LeoBodnar> BUt if you do it too slowly you can't get ahead of temperature increase of the environment.
[18:29] <Laurenceb_> but you take ~200s ?
[18:29] <LeoBodnar> However 1W heater should be OK
[18:29] <LeoBodnar> Yes
[18:29] <Laurenceb_> so you might manage to get most of the heat into the envelope
[18:31] <LeoBodnar> Yes, almost immediate injection. I am not sure though whether this is still adiabatic process
[18:32] <LeoBodnar> You have a sort of hot air bubble inside and how quickly it mixes up with the rest who knows. I suspect it does not matter
[18:32] <Laurenceb_> prob not
[18:33] <LeoBodnar> Hotter He just expands more so if averaged over total volume you probably arrive only at total energy and not specifics of its distribution
[18:33] <Laurenceb_> yeah
[18:34] <LeoBodnar> So when it gets back up hotter than the environment, how long will it keep the energy in? It will probably yo-yo down again but would be nice to estimate heat loss
[18:34] <Randomskk> you should get a nice little convection mixing cell going
[18:34] <Randomskk> if the heater's bottom middle

[18:35] <Laurenceb_> LeoBodnar: basically you are giving it a kick
[18:35] <Laurenceb_> once it starts going back up it should be stable again
[18:35] <LeoBodnar> IT overshoots and wants to go back
[18:35] <Laurenceb_> hmm

[18:36] <LeoBodnar> Don't want to add to instability...
[18:36] <Laurenceb_> hopefully itd be stable - catastrophic descent dont seem to be that common
[18:36] <Laurenceb_> it will have reached thermal equilibrium by the time it gets back to float
[18:36] <Martin_G4FUI> I've been pondering about today's fantastic mission, and I'm intreagued how TED was cut down so shortly before the apex of the ascent ... presumably the cutdown was pre-programmed ?
[18:36] <Laurenceb_> youd set the heater to fire at like 2Km altitude or somehting
[18:36] <LeoBodnar> Making it stop and go up would nice even if done once just to prove the concept
[18:36] <Laurenceb_> yes

[18:37] <LeoBodnar> I think 1000m below projected float altitude.
[18:37] <LeoBodnar> Why wait?
[18:37] <Laurenceb_> guess so
[18:37] <Laurenceb_> i was reading the papers on liquid based altitude hold
[18:37] <LeoBodnar> 2km might be too late as a lot weather is happening there
[18:37] <Laurenceb_> they used R114, no longer available
[18:38] <Laurenceb_> but apparently ammonia+water+hydrogen gas works
[18:38] <Laurenceb_> i.e. ammonia solution
[18:38] <SpeedEvil> use R101
[18:38] <SpeedEvil> :)
[18:38] <SpeedEvil> Only if it doesn't feeze?
[18:39] <Laurenceb_> i think the freezing point is quite low
[18:39] <SpeedEvil> Can you remind me what the point is again - to have a liquid which is more responsive to the thermal lapse rate than expansion due to loweing pressure?
[18:39] <LeoBodnar> This? http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/33268/1/94-1206.pdf

[18:42] <SpeedEvil> (It is possibly contaminated, and i don't know what with - and there is too much of it to go in the bin)
[18:42] <Laurenceb_> as a gas adsorper
[18:42] Nick change: KipK_away -> Kipkool
[18:42] <SpeedEvil> As a fun aside - damp activated carbon burns just fine.
[18:42] <SpeedEvil> Though obviously really slowly
[18:42] <Laurenceb_> interesting
[18:43] <Laurenceb_> i was looking at an inductrac based hyperloop
[18:43] <LeoBodnar> Will it not oxidise naturally with time?
[18:43] <Laurenceb_> its massively cheaper and easier
[18:44] <Laurenceb_> laminated alu foil for the tracks costs about £50/meter
[18:44] <Laurenceb_> activated carbon doesnt oxidise in room temp air
[18:44] <Laurenceb_> not enough energy
[18:45] <LeoBodnar> So it is not exponentially slow, it does not happen at all below certain energy threshold?

[18:47] <LeoBodnar> nurse!
[18:47] <Laurenceb_> lolz
[18:49] <Laurenceb_> hmm i guess even with 3grams free lift you still have potential instability
[18:49] <Laurenceb_> you prob need like 10 or more grams to be completely stable under all conditions
[18:49] <Laurenceb_> how annoying
[18:50] <Laurenceb_> i guess tropospheric superpressure just isnt nice
[18:50] <LeoBodnar> I think it might be even worse because you'll have more He on your hands to deal with and at least 3g lift eaten away
[18:50] <LeoBodnar> So you notice the problem much later
[18:51] <Laurenceb_> its fundamentally unstable
[18:51] <LeoBodnar> yeah, just need least energy hungry way of controlling it. Basically mild version of hot air balloon
[18:52] <Laurenceb_> if you had another envelope with the right hydrocarbon gas and some air

[19:02] <Randomskk> the onboard serial bootloader is easy if you just want to program
[19:02] <ed__> don't need to
[19:02] <Randomskk> asking jcoxon :P
[19:02] <ed__> i have a makefile now that just does make flash
[19:02] <Randomskk> I recommend getting a black magic probe
[19:02] <ed__> which abstracts all the annoyance away
[19:03] <Randomskk> ed__: yea libopencm3 comes with that, but it still uses openocd generally
[19:03] <ed__> 'annoyance', by which i mean just to get some code onto the flash
[19:03] <Laurenceb_> i just use the st lib
[19:03] <jcoxon> Randomskk, ummm still getting my head around how it works
[19:03] <jcoxon> was following a guide that used openocd
[19:04] <LeoBodnar> So going back to supercooled balloon how would one estimate the time constant? I don't remember gas theory that well.
[19:04] <Laurenceb_> so 1Km/(1m/s)=1000s
[19:05] G8KNN (~jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) left irc: Ping timeout: 240 seconds
[19:05] <Laurenceb_> 1Km = 10C/Km adiabatic lapse rate / delta temperature
[19:05] <LeoBodnar> Let's say everything is stationary but balloon is 10 degrees colder than the environment.
[19:06] <Laurenceb_> so it falls
[19:07] <LeoBodnar> OK, let's look at superheated balloon floating at 8000m. After the sunset is started descending within 2 hours
[19:07] <LeoBodnar> I would estimate it being hotter by 10-15C. So heat loss must be reasonably quick.
[19:07] <Upu> All I can say is its a good job Dan Bowen isn't here ..

[19:08] <Laurenceb_> seems a lon time intuitively
[19:08] <Laurenceb_> but the conditions are a little weird
[19:10] <LeoBodnar> I wonder if I can stick some helium in the foil balloon to get slight negative buoyancy and test the heater idea to see if I can control its ascent and estimate the time constant.
[19:11] <Laurenceb_> good idea
[19:11] <LeoBodnar> A little is a massive understatement!
[19:12] <LeoBodnar> Both my balloons went down with solid cloudbase underneath. I am sure lack of IR played some role there.

[20:15] <Laurenceb_> http://ballonsolaire.pagesperso-orange.fr/en-historique3.htm
[20:16] <LeoBodnar> It relies on IR emission but what happens when there is dense cloud cover below?
[20:17] <LeoBodnar> I keep thinking that what helps make balloon unstable. If IR is there the balloon maintains positive supertemperature
[20:17] <Laurenceb_> hmm
[20:18] <LeoBodnar> Both of my balloons that did "the dive " were of the are of dense cloud cover and rain

[20:27] <WillTablet> Will just ignore it
[20:27] <Geoff-G8DHE-M> The Dew Pt temp is -40c so would not moisture simply freeze out onto the balloon surface ?
[20:28] <LeoBodnar> As soon as you sort thermal runaway descent problem, frost and supercooled water is the next bugbear
[20:28] <Geoff-G8DHE-M> given that the temperature was down at those levels, which it was
[20:29] <Laurenceb_> http://www.scielo.cl/fbpe/img/jcchems/v56n2/fig9.1.gif
[20:29] <Laurenceb_> looks pretty black to me
[20:29] <SpeedEvil> There are ways to sort that Laurenceb http://www.ebay.co.uk/itm/330740901313
[20:29] <Laurenceb_> <Geoff-G8DHE-M>: i think you have it the wrong way around
[20:29] <Laurenceb_> its too hot for the remaining moisture to come out
[20:30] <LeoBodnar> It's black!
[20:30] <Laurenceb_> 1000cm^-1 is the region the thermal IR will be in
[20:31] <Geoff-G8DHE-M> Right ... I'll have tothink about that, I thought that the Dew Pt. waas the temperature that the moisture would come out at!
[20:31] <LeoBodnar> So it absorbs enough IR to stay warmer than air if IR is coming from below (or above)
[20:31] <Laurenceb_> if it was going to come out it already would have done
[20:31] <Laurenceb_> - the moisture
[20:32] <Geoff-G8DHE-M> If it had something to form on surely, the balloon surface would be ideal, otherwise its only atmospheric dust or am I still missing something ?
[20:32] <WillTablet> ed__ is topology particularly interesting? Just wondering if it's worth trying to figure the diagram out
[20:33] <Laurenceb_> <Geoff-G8DHE-M> dust, cosmic ray ionisation trails, anything really
[20:33] <ed__> it's probably among the bits of maths i'm least qualified to share an opinion about
[20:33] <LeoBodnar> It's complicated... If balloon is supercooled would it not create a film of air that will have 100% humidity and kick off ice formation on the surface?
[20:33] <Laurenceb_> bbl
[20:33] <ed__> beyond handwavey stoner crap about how all algebras are just a topology
[20:34] <LeoBodnar> BBC said bacteria is the best water accumulation object
[20:34] <Laurenceb_> i guess maybe it would in theory
[20:34] <Laurenceb_> but in reality its going to pick up moisture and ice
[20:35] <Laurenceb_> if the conditions were right
[20:35] <Laurenceb_> but i dont think they were from that diagram
[20:35] <Laurenceb_> it looks like a simple subcooled decent problem to me
[20:35] <LeoBodnar> Yep, it seems to be a practical problem encountered before, not a dreamt up concept.
[20:36] <Laurenceb_> ok bbl 4 real
[20:36] <Geoff-G8DHE-M> What would you need to measure to prove the supercooling theory ?
[20:36] <LeoBodnar> Subcooled descent is a nice theory please don't ruin it for me, I just got to accept it as reality XD
[20:36] <Geoff-G8DHE-M> :-)
[20:37] <LeoBodnar> It just seems so natural :)
[20:37] <LeoBodnar> Not much Geoff-G8DHE-M
[20:37] <LeoBodnar> I need to think about facts that would back this theory up
[20:38] <LeoBodnar> I guess internal / outside temperatures are enough
[20:38] <LeoBodnar> The rest can be derived
[20:38] <Geoff-G8DHE-M> You had that on one flight I think ?
[20:38] <Geoff-G8DHE-M> what about pressure as well ?

[21:32] <Willdude123> I could cover it with pictures of naked people.
[21:32] <Randomskk> post-irony
[21:32] <Willdude123> :)
[21:32] <Randomskk> you could but that's almost too obvious
[21:32] <KF5WYX> paste it cover-to-cover with cut-outs from the Tango & Cash movie.
[21:32] <Randomskk> or like, my little pony prints

[21:33] <Willdude123> Hmm. It's gotta be beautiful.
[21:33] <Willdude123> Me!
[21:33] <Willdude123> I could put a picture of me on it.
[21:33] <mattbrejza> make a larger image out of lot sof little ones
[21:33] <Willdude123> I think covering it in duct tape might make it beautiful.
[21:33] <mattbrejza> and if you make the larger picutre rude you can pretend it was an accident
[21:34] <KF5WYX> photograph your eye close up and paste that. (the eye of the beholder)
[21:34] <KF5WYX> I'm off home from work - will ping back shortly.
[21:34] <Lunar_Lander> take daves photo of another HAB at 34 km

[21:57] <Babs___> daveake: Quality jump! Nice clouds below as well, framed him superbly.
[21:57] <daveake> yes looked great
[21:58] <Babs___> You get so much of a sense of zero (ok, pretty much zero) air resistance
[21:58] <Babs___> He just keeps on accelerating
[21:58] <daveake> I know!
[21:58] <Babs___> I didn't know you were going today, I spent all day clearing drains
[21:58] <daveake> tsk
[21:58] <Babs___> Well - the morning
[21:58] <Babs___> He got recovered ?
[21:59] <Lunar_Lander> daveake, awesome
[21:59] <Lunar_Lander> did he say "I'm coming home now" at the beginning?
[21:59] <Lunar_Lander> :)
[21:59] <daveake> Yes both payloads recovered
[21:59] <arko> do it again!
[21:59] <daveake> LL no and he didn't have any tantrums either
[21:59] <arko> :P
[21:59] <Lunar_Lander> xD
[21:59] <Babs___> Brilliant, brilliant. Congrats.

[22:00] <fsphil> I just wish it had landed in a zoo
[22:00] <daveake> lol
[22:00] <Babs___> I hope he didn't land on his antenna
[22:00] <fsphil> och
[22:01] <Babs___> That could hurt
[22:01] <daveake> It was ... flattened
[22:01] <Babs___> Arf
[22:01] <fsphil> the antenna got tangled up quite quickly in the video
[22:01] <fsphil> which probably explains the signal drop
[22:01] <fsphil> it did well though, I decoded a lot more than I expected to
[22:02] <daveake> Have you filled in the 600 baud record table yet? :)
[22:03] <arko> daveake: http://youtubedoubler.com/9QSU
[22:03] <arko> had to see it side by side :)
[22:03] <daveake> lol :)
[22:04] <fsphil> the bear was better
[22:04] <arko> agreed
[22:04] <arko> he did a cartwheel
[22:04] <tweetBot> @daveake: Babbage vs Felix http://t.co/3DbSxJM2L4 #RaspberryPi #UKHAS
[22:04] <arko> at least he did tricks
[22:04] <daveake> haha
[22:05] <fsphil> you can make him out even at the end of the video
[22:05] <Randomskk> no video from babbage himself yet?
[22:05] <fsphil> just a dot though
[22:05] <daveake> corrupted sd card might get part of it
[22:06] <Randomskk> :(
[22:06] <daveake> hence kernel messages and lack of ssdv on the way down
[22:06] <Randomskk> mm
[22:06] <arko> are you able to get a bit image of the sd card?
[22:06] <Randomskk> shame
[22:06] <daveake> have done
[22:06] <fsphil> lucky it still transmitted telemetry tbh
[22:06] <daveake> not luck :)
[22:06] <Randomskk> yea indeed
[22:06] <daveake> planning :)
[22:06] <Randomskk> haha
[22:06] <fsphil> ah ha
[22:06] <Randomskk> cool that it transmitted kernel errors as well, then :P
[22:07] <fsphil> lol
[22:07] <fsphil> "Press any key to continue"
[22:07] <daveake> yes unexpected thought I'd turned that off :)
[22:07] <mattbrejza> undelete programs?
[22:08] <fsphil> are there any for ext fs?
[22:08] <Randomskk> there are various tools
[22:08] <Randomskk> you probably want something more sophisticated
[22:08] <Randomskk> ext3 or 4 or..?
[22:09] <Randomskk> I'd just try fsck on the disk image
[22:09] <Randomskk> how big is the image?
[22:09] <daveake> 8GB
[22:09] <Randomskk> ntb
[22:09] <daveake> fsck has been running for a while now
[22:10] <Randomskk> oh cool
[22:10] <Randomskk> which ext?
[22:10] <daveake> I'll leave it overnight
[22:10] <Babs___> Have any of you guys used an arduino due?
[22:10] <Randomskk> if fsck can't help it then you might be in for a more exciting time
[22:10] <daveake> :p
[22:10] <Randomskk> still if the video was recording to disk then it should have flushed a keyframe before impact
[22:10] <daveake> 3 I think
[22:10] <Randomskk> oh well - when do you think the sd card went sad?
[22:11] <daveake> At 39km when it jumped,, or soon after
[22:11] <Randomskk> oh bummer
[22:11] <Randomskk> that might be less optimistic
[22:11] <Randomskk> still. here's hoping
[22:11] <daveake> Video started at 38km IIRC
[22:11] <daveake> Yeah, well the stills should all be there

[22:11] <Randomskk> yea
[22:11] <Randomskk> anyway you still have the other video which is amazing
[22:12] <daveake> It is great :)
[22:12] <daveake> I roared when I saw that first time, full screen
[22:13] <daveake> Not sure why the animation got the wrong frames, but I can re-run that part to find out
[22:14] <fsphil> yea the animation seems to happen before that video starts
[22:15] <daveake> It does
[22:16] <Lunar_Lander> daveake, congratulations again
[22:17] <Lunar_Lander> you did four payloads today, did I get this right?
[22:17] <daveake> cheers, was a lot of fun
[22:17] <daveake> me? 2 on one flight
[22:17] <Lunar_Lander> yea
[22:17] <daveake> plus helped out JFS. They used their own payload plus a PAVA with my code on it as a backup
[22:17] <Lunar_Lander> yeah
[22:17] <Lunar_Lander> so BUZZ was on the JFS
[22:18] <Lunar_Lander> because it was your code
[22:18] <daveake> yes
[22:18] <Lunar_Lander> :) cool
[22:19] <daveake> I just put a pava in a ball and attached under their payload

[22:58] <WillTablet> I neeeeed a quadcopter.
[22:58] <WillTablet> Can't afford one
[22:59] <craag> Yeah they're pricey, and a lot of work to get going I think.
[22:59] <WillTablet> craag how do you come up with so many cool projects?
[22:59] <craag> WillTablet: Mainly I see a problem and try to solve it.
[23:00] <WillTablet> I can't see problems
[23:00] <craag> Sometimes the project goes nowhere, and ends up as a stagnant github repository.
[23:00] <WillTablet> He
[23:00] <WillTablet> Heh
[23:00] <WillTablet> I just can't think of any problems that need fixing

[23:10] <craag> Ok, keep at it. Remember you get the bandplan to look at, so the rest of the licensing is common sense really.
[23:10] <craag> Currently yes.
[23:10] <craag> There was a plan to do HF field day as well, but most of our club are away.
[23:11] <WillTablet> Indeed
[23:12] <WillTablet> How come ssdv seems to be a lot more talked about when you can have fstv on a payload?
[23:12] <craag> erm you can't really do fstv in the UK
