[00:00] <Paradoxial> Rent a boat
[00:00] <Gillerire> off to work - I'm late!
[00:00] <SpeedEvil> Maybe 4.
[00:00] <SpeedEvil> Paradoxial: There is nobody involved nearby
[00:00] <Paradoxial> :(
[00:00] <polycarbonate1> I'd be in a dinghy right now if I were near Sydney
[00:00] <SpeedEvil> Paradoxial: And it's a _tiny_ thing to find in the water
[00:00] <Paradoxial> Rent a helicopter
[00:00] <Laurenceb> i think it will wash up in wollondong
[00:00] <SpeedEvil> Though you do actually have a _really_ good position
[00:00] <radicalbiscuit> rent a new balloon
[00:00] <polycarbonate1> haha
[00:00] <SpeedEvil> You can probably guess the landing spot to within 30m or so.
[00:01] <SpeedEvil> Well - maybe 60
[00:01] <SpeedEvil> But not too far.
[00:01] <Lunar_Lander4811> juxta_ do you have some data on the 50g payload?
[00:01] <juxta_> Lunar_Lander4811, we will later
[00:01] <juxta_> we're all pretty sleep deprived now
[00:02] <Lunar_Lander4811> thanks
[00:02] <SpeedEvil> Drove most of the night to get back?
[00:02] <juxta_> SpeedEvil, yeah
[00:02] <polycarbonate1> good work guys, talk again tonight

[00:02] <Lunar_Lander4811> almost 24 hours aloft!
[00:03] <juxta_> over 24 hours
[00:03] <juxta_> about 24.5 hours
[00:03] <Lunar_Lander4811> ah
[00:03] <Lunar_Lander4811> because habitat stopped at 23:57
[00:03] <juxta_> it was launched at 23:30 the day before
[00:03] <Lunar_Lander4811> yes
[00:04] <juxta_> time to try get some sleep
[00:04] <Lunar_Lander4811> VK2HRX is the guy :)
[00:04] <Lunar_Lander4811> he got the landing for us
[00:05] <Lunar_Lander4811> good night juxta_
[00:05] <Lunar_Lander4811> congratulations
[00:05] <Dan-K2VOL> congratulations indeed! night juxta_
[00:05] <SpeedEvil> It'd have landed at 23:58 I think

[00:10] <Lunar_Lander4811> Dan-K2VOL : last night when the balloon levelled off I thought if a ballast drop could have made it punch through upwards
[00:10] <Dan-K2VOL> you bet
[00:10] <Lunar_Lander4811> but now that I heard that it only weighed 50g total
[00:11] <Dan-K2VOL> wonder what the batts were

[00:16] <Demon> Ugh.
[00:16] <SpeedEvil> It's a 60 gram package.

[00:16] <Demon> 60 gram ?
[00:17] <SpeedEvil> It was known 20 minutes ago where it was to within about 60m.
[00:17] <SpeedEvil> But, by the time a boat was got out to it - say now - it might have floated a large slice of a kilometer.
[00:18] <Demon> Well, next time think about a mech drop
[00:18] <Demon> Sorry for the lost
[00:18] <SpeedEvil> It adds cost.

[00:18] <shenki> it landed ~1200km from where we launched it, as the crow flies
[00:19] <shenki> s/we/the team/
[00:19] <pod> so, itll wash up on a beach, 50/50 chance
[00:19] <shenki> :)
[00:19] <vk5gr> the rip's off the coast nr there might not let it
[00:19] <shenki> the last time it landed we kept getting telemetry once it splashed
[00:19] <shenki> is anyone still listening?
[00:21] <pschulz01> Map indicates that VK2HRX was the last to receive a packet.
[00:23] Bryanstein (~Bryanstei@shellium/admin/bryanstein) joined #highaltitude.
[00:26] <PsionicOz> VK2HRX is about 50-100kms away... the fact he could hear it 312m LOS is impressive.
[00:27] <PsionicOz> our payload will eventually sink beneath the waves.. that part of the coast is rocky and quite nasty.
[00:27] <Lunar_Lander4811> OK
[00:27] <Lunar_Lander4811> time for good night

[00:29] <PsionicOz> we'll see wb8elk.. it's over 1200km from us as the crow flies in a very nasty coast line... We turned back after 550kms last night... otherwise we'd have been in Sydney this morning.

[00:32] <eroomde_> Hello
[00:32] <Dan-K2VOL> hey ed
[00:33] <eroomde_> Bad news ?
[00:33] <Dan-K2VOL> just missed all the calamity
[00:33] <Dan-K2VOL> HORUS 16 is down in the water, about 30 min ago
[00:33] <Dan-K2VOL> 23h 57min I think total flight time
[00:34] <eroomde_> Well, that was one long track to no avail
[00:34] <eroomde_> It's part of the hobby
[00:34] <eroomde_> Maybe a fisherman will pick it up in its nets :)
[00:34] <Dan-K2VOL> it will make interesting altitude charts
[00:34] <Dan-K2VOL> :-)
[00:35] <eroomde_> That's for sure
[00:35] <Dan-K2VOL> we watched it climb 1250m at sunrise
[00:35] <Dan-K2VOL> and establish float again
[00:35] <eroomde_> So the chart must look like a stretched "n"
[00:35] <eroomde_> What was the total travel ?
[00:35] <SpeedEvil> 1400km or so
[00:36] <SpeedEvil> It hit ~3km offshore
[00:36] <Dan-K2VOL> nice flight
[00:36] <eroomde_> In 24 hours, that means
[00:36] <eroomde_> An average of 60km/h

[00:37] <eroomde_> Well, this ending surely does'nt mean the end of it all ?
[00:38] <Dan-K2VOL> yep, that's the final flight of amateur ballooning
[00:38] <Dan-K2VOL> it's been fun
[00:38] <Dan-K2VOL> :-P
[00:38] <Dan-K2VOL> what do you actually mean ed
[00:38] <eroomde_> For sure
[00:38] <eroomde_> You answered what I feared, sadly
[00:39] <Dan-K2VOL> heh well, not if I can help it, we've got big plans here!
[00:40] <eroomde_> Tell me more
[00:40] <Dan-K2VOL> there's two speedball flights getting ready to go to you on the jet stream this winter,
[00:41] <Dan-K2VOL> and we're going to start building superpressure envelopes with Heptax
[00:41] <eroomde_> Wow, cool
[00:41] <Dan-K2VOL> I'd like to do a bunch of low altiude, lightweight test flights to make sure we're doing the math and procedures right
[00:42] <eroomde_> Would be wise
[00:42] <Dan-K2VOL> been thinking of getting someone to do an internet-linked mobile phone theodolite balloon tracker to allow no-payload flights
[00:43] <Dan-K2VOL> by having people sight along the edge of their phones at the low altitude balloon

[00:43] <eroomde_> Mhm...
[00:43] <Dan-K2VOL> low precision, but it would be a neat way to get normal citizens involved in tracking sometimes
[00:44] <Dan-K2VOL> the eventual goal will be a 200g payload superpressure at 14km
[00:44] <eroomde_> You would need a lot of people tracking on the ground
[00:44] <Dan-K2VOL> solar powered satellite telemetry
[00:45] <eroomde_> Better not launch at 12:00
[00:45] <eroomde_> The balloon might block the sun
[00:45] <Dan-K2VOL> lol
[00:46] <Dan-K2VOL> the Delorme Inreach would be freakin fantastic if it works and costs as advertised
[00:46] <Dan-K2VOL> as a two-way satellite service

[00:46] <eroomde_> Well, with theodolite the balloon would sure be payload-less but its a lot of logistics on the ground
[00:47] <eroomde_> bluetooth is not reputated for it's range
[00:47] <Dan-K2VOL> well, I'm thinking the iphone app and online tracker would take care of most of the ground complexity of theodolites - angles and position are available to the phone/tracker
[00:48] <eroomde_> So, the gound spotter aims with the edge of his phone ?
[00:48] <Dan-K2VOL> so you just set your phone on your car roof and aim your sight line along it's edge at the balloon

[03:12] <Darkside> nice
[03:12] <gm> 2nd hand but mint condition
[03:12] <Darkside> i'll be interested in checking out the I/Q features of it
[03:12] <gm> yeah
[03:12] <gm> so i'll be tracking the next launch
[03:12] <Darkside> you'll need a decent antenna first :P
[03:12] <gm> i have wire and a soldering iron :P
[03:13] <Darkside> haha
[03:13] <Darkside> yes
[03:13] <gm> hmm, andrews communications says IQ bandwidth is 86k
[03:13] <gm> manual says 96k
[03:14] <gm> but people on the mailing list say it's probably "96" because of most people's sound cards
[03:14] <Darkside> yeah
[03:14] <gm> if so, my MBP does 192k/24bit so i'll be happy :)
[03:14] <Darkside> yeees, that'd be interesting
[03:14] <Darkside> i doubt it'd be that wide though
[03:14] <gm> yeah
[03:15] <gm> but might be a bit wider than 96
[03:15] <gm> also has a discriminator out
[03:15] <Darkside> yeah
[03:15] <Darkside> oh man my macbook can do 192k
[03:15] <Darkside> awesome
[03:16] <gm> and something similar to close call but for trademark reasons not
[03:16] <Darkside> i know my old macbookcouldn't
[03:16] <Darkside> haha
[03:16] <gm> nearly all the high end apple gear can
[03:16] <gm> my old 15" could
[03:16] <Darkside> yeah, if the thing turns out to be good, i might get one
[03:16] <Darkside> esp if the I/Q bandwidth is wide
[03:16] <gm> i think my G4 could do 96k
[03:16] <gm> one review said: "The nearest competitors are the Icom R20 which costs about $225 more or the AOR8200 Mark III B at about $575 more"
[03:16] <gm> "The ace in the hole for the DJ-X11 is allowing access to the radios IQ signal. Using SDR software increase the receivers performance significantly by providing more sophisticated DSP processing and filtering, very possibly out performing other receivers in its class.
[03:17] <gm> i wonder... stick a raspberry pi board to the back on the IQ out to do digital modes
[03:17] <Darkside> i'd use a real RC tbh
[03:17] wolfspraul (~wolfsprau@mimi.q-ag.de) left irc: Quit: leaving
[03:18] <Darkside> PC*
[03:18] <Darkside> you need a bit of grunt for some of the signal processing
[03:18] <Darkside> but it could be interesting to do a simple RTTY decoder using something like that
[03:18] <gm> yeah, but you can't stick that onto the back of the radio
[03:18] <gm> you could do a RTTY decoder on an AVR
[03:18] <Darkside> theoretically
[03:18] <Darkside> using an external PLL is usually easier
[03:19] <Darkside> take the control voltage of the PLL as the digital data
[03:19] <gm> yeah
[03:19] <gm> two bandpass filters on two inputs :P
[03:19] <Darkside> eh?
[03:20] <Darkside> the problem with having a sharp filter on the input to the PLL is as soon as the signal drifts you'll lose it
[03:20] <gm> well RTTY is just swapping between two frequencies
[03:20] <gm> so you simply have two bandpass filters, and a detector
[03:20] <Darkside> the problem then is keeping the signal in tune to be able to decode
[03:20] <gm> and they don't have to be sharp because you just have to tell if it's one or the other
[03:21] <Darkside> yeah, you'd do that with an FFT, not a bandpass filter i think
[03:21] <Darkside> hell, you wouldn't even need a long FFT to do it!
[03:21] <gm> yeah, might be more sensible
[03:22] <gm> but with efficient algorithms, shouldn't be hard
[03:22] <gm> hmm, i wonder if my ALIX would be faster than raspberry pi
[03:22] <gm> 433mhz geode LX
[03:22] <gm> it has sound in
[03:22] <gm> and isn't too power hungry (for an x86 machine)
[03:24] <gm> but then again, newer ARM chips are getting that fast anyway
[03:26] <gm> anyways, i'd better actually head into town or i'll never get there
[03:26] <Darkside> heh
[03:26] <Darkside> i don't think i'll be heading in today

[07:33] <Darkside> damn long flight
[07:33] <Darkside> over 24 hours
[07:33] <daveake> Looked like it might hit land, then the jet stream took over at 200kph+
[07:33] <UpuMobile> recovered ?
[07:33] <Darkside> nope
[07:33] <Darkside> landed 5km offshort
[07:33] <UpuMobile> oh offhosire

[07:33] <daveake> Blimey, still up Darkside!
[07:34] <Darkside> nah, its gone

[07:42] <daveake> It was pretty exciting!
[07:42] <Darkside> heh
[07:42] <daveake> It did seem doomed when it hit the jet stream
[07:42] <Darkside> it may wash up on shore
[07:43] <daveake> Yep. I'll keep my fingers crossed for that. You can do the same for me ;)
[07:43] <daveake> Yours was closer to shore though
[07:45] <daveake> Morning RocketBoy
[07:45] <russss> well, it was a fun one :)
[07:46] <russss> if you do use a cutoff, just use it to avoid the sea, the flights which do unexpected things are the most fun
[07:46] <RocketBoy> Morning
[07:46] <daveake> You missed the excitement last night :(
[07:46] <RocketBoy> i see - and the tracker has been cleared
[07:46] <RocketBoy> :-(
[07:48] <daveake> It burst SW of Sydney, hit 200+kph and landed ~3 miles offshore
[07:48] <gm> stupid jetstream
[07:48] <daveake> indeed
[07:48] <gm> it'll wash up somewhere
[07:48] <gm> but damn, it could have been recovered

[08:17] <WillDuckworth> yeah - saw some of that, looked fun :)
[08:17] <daveake> It was, actually, despite the result.

[08:23] <number10> hey dave how long does you dell netbook battery last roughly would you say
[08:25] <daveake> I think it said 3.5 hours. I also have a battery in the DVD slot to get more. However I use a car power adapter for the chase
[08:27] <number10> I think I need to get one - this ballooning stuff will cost me a fortune
[08:28] <daveake> Previously I used a netbook which at least takes up less space. I just don't have working 3G on that at the moment. The Dell I bought an internal 3G card for,

[08:40] <TimZaman> hi
[08:44] <daveake> Morning Tim
[08:48] <TimZaman> mornin
[08:48] <TimZaman> i have a Question. I'm going to use the FTDI4232H (http://www.ftdichip.com/Products/ICs/FT4232H.htm)
[08:49] <TimZaman> Lets say i configure it for four UART outputs.. are those regular RXTX outputs on 3v3?
[08:49] <TimZaman> or should i include a MAX3243 or something
[08:49] <TimZaman> dont get its purpose
[08:51] <daveake> Yes, it says 3V3 interfacing, so going RS232 levels will mean a MAXnnnn
[08:51] <daveake> It's basically 4 UARTS connected to USB
[08:51] <TimZaman> this is going to sound stupid, so, why would i include the MAX tranceivers?
[08:52] <TimZaman> to get the 5V interfacing?
[08:52] <daveake> No it does 5V. You'd need those if you are going to true RS232 levels which are -3V to -12V or thereabouts
[08:53] <daveake> So it depends what you're plugging into
[08:53] <TimZaman> ah thanks. serial connectors i have never worked with (tend to keep it that way)
[08:53] <TimZaman> well, so i guess i can shoot that directly into an arduino or gps or whatever, right, if its 3v3 (which is exactly what i want)
[08:54] <Darkside> daveake: i see you there, playing silly buggers on the tracker

[08:58] <daveake> :)
[08:58] <TimZaman> ;)
[08:58] <TimZaman> so Darkside , whats the analysis.. it seems, as proposed earlier, that you need a good lift to achieve high altitude. what do you think

[10:00] <fsphil> blocking imap and pop??
[10:00] <BrainDamage> the only valid traffic in my univ is http and https, I have to resort using an http proxy, then ssh tunnel to get out
[10:00] <BrainDamage> https*
[10:00] <Laurenceb> Darkside: was the payload labled?
[10:00] <BrainDamage> the https proxy is sufficient to trick the firewall to think it's legit traffic, then I estabilish my tunnel
[10:00] <Laurenceb> i think it might wash up in Wollondong
[10:01] <BrainDamage> and do whatever I want
[10:01] <BrainDamage> but it'sa insane
[10:01] <BrainDamage> oh yea, I forgot, not even ftp is valid and I have to route that traffic trough the tunnel :/
[10:02] <Darkside> yes its labelled
[10:02] <gm> if they get smart, what you do is wrap SSH into SSL
[10:03] <gm> like with stunnel
[10:03] <gm> then serve that on 443
[10:03] <daveake> Some of my customers do this shit - blocvking ftp, external email, etc. Many of them however forget to block outgoing VPN, so I connect back to base and I'm sorted.
[10:03] <gm> because you can't block CONNECT to 443 without breaking SSL
[10:03] <gm> you can, however, check that it is a SSL handshake
[10:03] <BrainDamage> yes, that was what I was considering next
[10:04] <gm> but then because it's SSL, you can't see what's in it
[10:04] <gm> of course, if they start MITM'ing it based on their own cert... time to buy a 3G modem
[10:04] <BrainDamage> but it's truly insane I have to do this shit just to read emails

[10:33] <Lunar_Lander> xD yeah TimZaman
[10:33] <Lunar_Lander> will do that
[10:34] <Lunar_Lander> matt_work : I got arduino uno + mega, Venus GPS and NTX2 here

[10:34] <Lunar_Lander> here I did Upu's tutorial
[10:35] <matt_work> so surely the next stage is some velco board ontop of a mega?
[10:35] <matt_work> use sockets for the expensive stuff for now (gps/radio)
[10:37] <Lunar_Lander> yea
[10:37] <Lunar_Lander> you mean something like the protoshield that is available for the Uno?
[10:39] <matt_work> well cant u get some proto board and some header rather then buying a shield?
[10:40] <Lunar_Lander> true
[10:40] <Lunar_Lander> I got enough male and female headers here
[10:40] <Lunar_Lander> should be cheaper than buying it all

[10:46] <Lunar_Lander> is the board made of paper good enough or better to take epoxy?
[10:46] <Lunar_Lander> yea

[10:54] <Lunar_Lander> the first chute test will be a seven-story high building

[10:56] <BrainDamage> are you going to test in the cold too?
[10:57] <Lunar_Lander> yea we got a big fridge at uni
[10:57] <daveake> Lunar_Lander - as you're testing with a bag of sugar, I assume it's a largish payload with cameras?
[11:00] <Lunar_Lander> well
[11:00] <Lunar_Lander> wait
[11:00] <Lunar_Lander> it has no camera currently
[11:00] <Lunar_Lander> the box is about 30x16x12cm in size

[11:02] <matt_work> u already have a box but no payload :P

[11:03] <daveake> I need to check the logs but the int sensor at the top of the case got to around 50C. That's plus 50 not minus
[11:04] <Lunar_Lander> matt_work : yeah I went to the pharmacy and asked for a box :)
[11:04] <daveake> It cooled down by the time it came down, because the camera batteries weren't specced for a long flight!
[11:04] <Lunar_Lander> and I got flourescent orange acrylic paint
[11:04] <Lunar_Lander> yea
[11:04] <daveake> not pink :(

[11:04] <daveake> :)
[11:07] <Lunar_Lander> well the sugar is for the first test

[12:58] <number10> thats an aduino/ave function?
[12:59] <daveake> It's a C function. The Arduino issue is a lack of floating point conversions in sprintf
[13:00] <number10> ah - so the arduino has a problem in its sprintf
[13:00] <daveake> yes

[13:03] <daveake> Yes, it's one known to work. I put it in aircraft mode to make sure.
[13:04] <daveake> Some of them need that; I didn't know if this one did. I included code to switch off NMEA sentences that I wasn't decoding, and to switch to flight mode
[13:05] <daveake> My first flight I used an old GPS that I had sitting around. I couldn't find out for sure if it worked above 60k, but when I flew it, it did :)
[13:05] <daveake> During the flight someone googled and said it would fail.
[13:05] <number10> that was lucky - I like your give it a go sprirt

[13:20] <number10> is good
[13:22] <number10> daveake can you explain measuring next lift - do wou create a weight that is same as the paload minus the filling gear and attach that while you are filling - and then??
[13:22] <number10> wou == you
[13:24] <daveake> OK, the calculation you use for how much helium gives you the next lift. That number will be MORE than the weight of your payload. If it was the SAME as your payload then it will only just hold the payload off the ground - it won't actually lift it up.
[13:24] <daveake> neck* lift
[13:25] <number10> so you need more mass of helium than the payload - do you have a gage that measures the amount of helium going to the balloon?
[13:26] <daveake> Now, you need to measure that nick lift quite accurately otherwise the flight will go higher or lower than planned, and might float and might end up in the sea .... :p
[13:26] <daveake> No, you measure the helium by measuring the neck lift.
[13:27] <daveake> To do that you do is find or make something the same weight as that neck lift. minus the weight of your filler. Then you hang it from top of the filler. So now the balloon is trying to lift this weight plus the filler. When it *just* does that you're set.

[13:27] <daveake> The payload doesn't come into this bit at all.
[13:27] <number10> ic -
[13:28] <number10> so the weight is the next lift you have calculated that you want (- filling kit)
[13:28] <number10> neck
[13:28] <number10> ic - sorry for repeating - getting old
[13:28] <daveake> Yes. It comes from the calculation you've seen before.
[13:29] <number10> good - thanks
[13:29] <daveake> In my case it was 1.6kg, and my filler was 200g I think, so I used a lemonade bottle with 1.4kg of water in it. Something like that.
[13:29] <daveake> Say you've got a 1.8kg neck lift and a 1kg payload. 1.8kg minus 1kg give a "spare" 0.8kg of lift. That's what sends your balloon and payload into the sky.

[13:30] <daveake> Or in my case, nearly into a water tower :p
[13:30] <daveake> I got caught out by the wind
[13:31] <number10> must be difficult on a windy day
[13:31] <daveake> Last thing, if you're using a Hwoyee balloon, the calcs seem to be a bit different. If I was flying one tomorrow, and I wanted say 4 m/s ascent rate, I'd do the calc for 5 m/s to account for them going up a bit slower and flying higher. It is a bit of an unknown though. RocketBoy is collecting data on that.

[13:33] <number10> and if it goes up too fast does it have a tendancy to burst earlier
[13:33] <daveake> Yes
[13:33] <nosebleedKT> hi all
[13:33] <daveake> That's the balance ... more He ==> faster ascent but lower burst
[13:34] <daveake> Afternoon
[13:34] <number10> I'll have to pop along to watch one of the launches
[13:34] <daveake> For my flight, a faster ascent would have meant it travelling less distance towards the coast. So a certain amount extra and I'd have it back by now.

[13:37] <number10> takes about 1.5 hours there
[13:38] <daveake> Landing was closer to Thorpeness
[13:39] <daveake> 30mph sideways :(
[13:39] <number10> I was thinking that ebay GPS text thing to put in watertight bag
[13:39] <daveake> And a waterproof address/phone label
[13:39] <number10> yes
[13:40] <daveake> And photograph said label leaving photo on the camera
[13:40] <number10> I looked at the picture of horus 15.5 and think the label was just paper
[13:40] <daveake> Wish I'd thought of those two before the launch :(
[13:41] <number10> yes - is expensive - you lot are driving up the prices of cameras on ebay ;)
[13:41] <daveake> I've put an identical label in salt water at home. It's still stuck on and still easily readable but the ink is fading.
[13:41] <number10> maybe laminate the label
[13:42] <number10> try not to land buzz1 at sizewell as I think you would get the headlines

[18:59] <Lunar_Lander> yeah
[18:59] <Lunar_Lander> but connecting sensors is still a problem

[19:00] <jcoxon_> Lunar_Lander, goodness no
[19:00] <daveake> breadboard?
[19:00] <jcoxon_> Lunar_Lander, you can use stripboard instead
[19:00] <jcoxon_> most more secure
[19:00] <jcoxon_> much more secure*
[19:01] <daveake> Yep. Stuff will fall out of the breadboard as the box gets thrown around.
[19:01] <Lunar_Lander> yeah I saw that when I took my breadboard to uno
[19:01] <Lunar_Lander> *uni
[19:01] <Lunar_Lander> I had to replug all stuff before showing to my professor
[19:01] <Lunar_Lander> (and the NTX2 pins were bent!!)
[19:02] <daveake> Stripboard, or if you're using a standard or mega Arduino then you can get a prototyping board that plugs in.
[19:02] <Lunar_Lander> yeah
[19:02] <daveake> I flew one first time.
[19:02] <Lunar_Lander> like this http://www.sparkfun.com/products/9346 ?=
[19:02] <daveake> You can mount NTX2 and a other bits to one. could be a bit tight for space if you've got a few things added
[19:03] <daveake> Yeah, but that one looks quite expensive

[19:13] <Lunar_Lander> hey Paradoxial
[19:13] <Paradoxial> Hi Lunar
[19:13] <daveake> The pattern varies, but basically there'll be little tracks of maybe 3 holes in a row, plus longer tracks for power lines. Then you fit components and wires to them. They're cheap enough to get 2 or 3 different ones in and see which works best for your design.
[19:14] <daveake> Or just get stripboard and a tracker cutter tool and the pin headers
[19:14] <Lunar_Lander> oh there are lines already?
[19:15] <daveake> One the ones I've seen, yes.
[19:15] <Lunar_Lander> ah

[20:03] <daveake> cheap
[20:03] <TimZaman> the Pandaboard actually has a four port HUB.. but there are two hubs on the panda. Confusing -but no-.
[20:04] <TimZaman> turns out they broken out the V,Gnd,D+,D- on an expansion perhipial
[20:04] <TimZaman> which means i can stack it
[20:04] <TimZaman> heeeellll yeah
[20:04] <Lunar_Lander> cool
[20:04] <Lunar_Lander> YAY I found a 20x10 cm veroboard :)
[20:05] <TimZaman> that means 5 less USB wires javascript:;
[20:05] <Lunar_Lander> which is good
[20:05] <Lunar_Lander> as mega is 11x5.3cm roundabout
[20:05] <TimZaman> ewww veroboard
[20:05] <TimZaman> Lunar_Lander: why dont you just get a protoboard, those are quite cheap usually
[20:06] <daveake> And round the circle we go :D

[20:08] smea (~smealum@85-171-203-85.rev.numericable.fr) left irc: Read error: Connection reset by peer
[20:08] <TimZaman> veroboard is messy, and only a few euros cheaper
[20:08] <Lunar_Lander> ah
[20:09] <Lunar_Lander> and in protoboard you have to do all traces yourself, right?
[20:09] smea (~smealum@85-171-203-85.rev.numericable.fr) joined #highaltitude.
[20:09] <daveake> varies
[20:10] <TimZaman> there are protoboards with built in microsd
[20:10] <TimZaman> interfacing those can be a bitch
[20:10] <TimZaman> especially when youre going for the arduino mega
[20:10] <TimZaman> those MISO/MOSI/CS etc pins are off
[20:11] <Lunar_Lander> yeah
[20:11] <TimZaman> but you'll find that out soon enough
[20:11] <Lunar_Lander> and for a big SD?
[20:11] <TimZaman> if not already
[20:11] <TimZaman> big sd same thing
[20:11] <TimZaman> dont use >2gb
[20:11] <TimZaman> (fat32)
[20:11] <Lunar_Lander> yeah
[20:12] <Lunar_Lander> because I saw the big SD breakout has more pins than the microSD one
[20:13] <daveake> You don't need all the pins - just the spi and power/gnd ones

[20:22] <Lunar_Lander> SD breakout has a CLK pin
[20:22] <Lunar_Lander> is that used to get a time signal for logging things?
[20:22] <daveake> no

[20:24] <Lunar_Lander> yes
[20:24] <Lunar_Lander> so the arduino just has to create strings?
[20:26] <daveake> Yes, you send the strings out of a serial port and into the Openlog. job jobbed.

[20:56] <griffonbot> Received email: Peter "[UKHAS] Re: HOWEST Launch tomorrow"
[20:56] <danielsaul> priyesh: thinks it needs activating or something
[20:57] <TimZaman> so i think i have to go with the tethering
[20:57] <priyesh> i do
[20:57] <fsphil-laptop> there is a launch tomorrow
[20:57] <priyesh> maybe i'm wrong
[20:57] <fsphil-laptop> oh there it is
[20:57] <natrium42> TimZaman: older camera with usb capture would be the best solution
[20:57] <TimZaman> fsphil rly
[20:57] <TimZaman> natrium42: indeed.
[20:57] <priyesh> fsphil-laptop: i believe the launch will be over by the time we need it.
[20:57] <fsphil-laptop> TimZaman, HOWEST in Belgium
[20:57] <TimZaman> then ill use gphoto2, seems to work nicely
[20:57] <fsphil-laptop> you should be able to track it infact
[20:57] <TimZaman> HOWEST?
[20:57] <Lunar_Lander> yea, GOWEST was already occupied by Pet Shop Boys
[20:57] <TimZaman> HAhah!
[20:57] <Lunar_Lander> xD
[20:57] <TimZaman> those guys contacted me ages back
[20:58] <natrium42> TimZaman: the problem with gphoto2 is that it extends and retracts lens for every shot
[20:58] <TimZaman> :|
[20:58] <natrium42> i didn't find a way to fix that
[20:58] <natrium42> you could use capture
[20:58] <Lunar_Lander> TimZaman : what did they ask you?
[20:58] <natrium42> http://capture.sourceforge.net/
[20:59] <TimZaman> Lunar_Lander: dont know, was something with westvlaanderen
[20:59] <Lunar_Lander> oh ok

[20:59] <natrium42> bbl
[20:59] <TimZaman> natrium42: lol i have 3 canons, all not compatible :)
[20:59] <natrium42> ouch
[21:01] <fsphil-laptop> I was hoping to find a way to have chdk transfer images but it doesn't seem possible
[21:03] <TimZaman> fsphil you're the man if thats possible
[21:04] <priyesh> so if we start decoding, it'll appear on spacenear.us
[21:04] <priyesh> without any 'activation'?

[21:04] <fsphil-laptop> is the payload definition been setup in habitat?
[21:04] <fsphil-laptop> has*
[21:04] <staylo> fsphil-laptop: Transfer images how?
[21:05] <priyesh> yes
[21:05] <priyesh> fsphil-laptop: yes
[21:05] <fsphil-laptop> should work I think
[21:05] <fsphil-laptop> staylo, I never got past the how bit :)
[21:05] <priyesh> thanks. will try tomorrow
[21:05] <priyesh> there isn't a way to manually add a packet is there?
[21:05] <TimZaman> priyesh: there is
[21:06] <priyesh> is there a link i can have to it?
[21:06] <priyesh> please
[21:06] <TimZaman> well for what i know you should not just put anything in
[21:06] <staylo> fsphil-laptop: Good point :) What do you want to transfer to? A USB host or something more basic?

[21:31] <fsphil-laptop> staylo, avr chip
[21:31] <fsphil-laptop> was kinda hoping the canon's had a serial port or something
[21:39] <staylo> slightly hacky but the LED on the little-used 'print' button is often repurposed for blinking out data. This is how many of the cameras had their firmware dumped. I gather recent CHDK builds have an implementation of the USB PTP protocol, so perhaps low level control of the USB data lines is available now too..
[21:40] <fsphil-laptop> I'd wondered about using the led.. though a bit hacky for that first flight
[21:41] <fsphil-laptop> idle thought -- just watching tim's launch, the parachute opens up during ascent
[21:42] <fsphil-laptop> would that have a big impact on the ascent rate?
