[08:12] <Upu> Morning
[08:12] <Upu> I've made something that works, this is rare for me :)
[08:17] <juxta> hey Upu - what've you made? :)
[08:23] <Upu> A flight computer
[08:23] <Upu> Even though we were convinced we'd cooked the GPS when soldering it
[08:23] <Upu> http://ava.upuaut.net/files/avafc.jpg
[08:24] <Upu> If you check www.spacenear.us/tracker it's transmitting :)
[08:24] <juxta> sweet, nice job :D
[08:24] <juxta> what GPS module is that?
[08:24] <Upu> Inventek High Altitude build ISM 300
[08:25] <Upu> They are only $25 each but nasty to solder
[08:25] <juxta> wow, that's really cheap
[08:25] <Upu> Maximum altitude of 42000 meters (137795 ft)
[08:26] <Upu> sorry $32.95
[08:26] <Upu> http://inventeksys.accountsupport.com/store/ISM300F2-C5-V0004.html
[08:26] <Upu> they've gone up
[08:28] <juxta> still, very cheap
[08:28] <juxta> what does an antenna to suit cost?
[08:29] <Upu> let me check
[08:30] <Upu> $10
[08:30] <juxta> looking at the same site they seem to be <$10
[08:30] <Upu> http://inventeksys.accountsupport.com/store/gps_antennas.html
[08:30] <juxta> thats very reasonable
[08:30] <Upu> Apparently the chip isn't good for fast updates like UAV etc
[08:31] <Upu> and check the tracker it's wandering a little but tha's only 10 meters max
[08:31] <Upu> and it is in a basement on the window sill at the moment
[08:31] <Upu> so impressed it's got any satellites tbh
[08:32] <juxta> yeah the wander is pretty normal
[08:33] <Upu> anyway back to work

[16:25] <jonsowman> oh poo
[16:25] <jonsowman> sorry
[16:26] <fsphil> hmm
[16:26] <m1x10> arduino selects boards based on Mhz
[16:26] <m1x10> so now its set at sanguino 16mhz
[16:26] <fsphil> the bootloader probably sets up the baud rate expecting the wrong crystal
[16:28] <fsphil> if you program it with the original crystal, then replace it with the new one, does your program run?
[16:28] <m1x10> no
[16:28] <m1x10> i uploaded code with 16mhz
[16:28] <m1x10> then changed crystal to 14...
[16:29] <m1x10> and console prints garbage!
[16:29] <fsphil> did you change how you setup the serial port in your code?
[16:30] <m1x10> of course
[16:30] <fsphil> if your seeing garbage then it means it's sending something
[16:31] <fsphil> the problem must be a matter of timing somewhere
[16:32] <m1x10> everything is untouched
[16:32] <fsphil> did you update F_CPU?
[16:32] <m1x10> nop
[16:32] <m1x10> where is this?
[16:33] <fsphil> not sure, not familiar with arduino libraries

[16:34] <fsphil> or boards.txt

[16:36] <m1x10> should change this to 14.7456
[16:37] <fsphil> yep
[16:37] <m1x10> should change this to 14745600L
[16:37] <fsphil> that looks about right
[16:39] <m1x10> but i should set those features on the mcu too
[16:39] <m1x10> not just on the textfile
[16:40] <fsphil> I'm not sure
[16:41] <m1x10> those flags are the fuses?
[16:42] <fsphil> probably don't need to change the fuses
[16:43] <fsphil> sooo tempting: http://habhub.org/predict/#!/uuid=65db13dfdea7358731ff331318053476e8adf14b
[16:44] <m1x10> the Makefile has F_CPU = 16000000
[16:45] <fsphil> change that too
[16:45] <fsphil> infact that's probably the most important one
[16:45] <m1x10> yes but i need to complile!
[16:49] <m1x10> ok did it
[16:49] <m1x10> up and running!
[16:54] <m1x10> ok when im uploading with 14mhz its not working.I have to put the 16mhz crystal to upload. Then change to 14mhz then run
[16:56] <m1x10> at 38400 works

[23:13] <jcoxon> ping eroomde
[23:15] <eroomde> jcoxon
[23:16] <jcoxon> hey!
[23:17] <jcoxon> i was expecting a 3hr lag
[23:17] <eroomde> bit faster right now
[23:17] <eroomde> i'm between stretch-and-folds on my sourdough
[23:17] <jcoxon> oh right
[23:17] <jcoxon> been playing with the source code on the rfbees
[23:17] <eroomde> final shaping in 30 mins then into the baneton to proof in the pantry overnight
[23:18] <eroomde> ok cool - any interesting tidbits?
[23:19] <jcoxon> i've added a 'heartbeat' function
[23:19] <jcoxon> every 10 secs
[23:19] solistice (4a680490@gateway/web/freenode/ip. joined #highaltitude.
[23:19] <jcoxon> so multiple balloons...
[23:19] <jcoxon> i was thinking:
[23:19] <jcoxon> 'recon' balloon = gps + rfbee
[23:20] <jcoxon> then relay balloon = rfbee + ntx2 + gps
[23:20] <jcoxon> then ground station = rfbee + ft817 etc
[23:20] <eroomde> I'm positively wet at the thought
[23:20] <eroomde> what's the LOS range (claimed)?
[23:21] <solistice> umm, hello
[23:21] <solistice> ?
[23:21] <eroomde> hello solistice
[23:22] <jcoxon> eroomde, 120m it claims
[23:22] <jcoxon> i don't believe it
[23:23] <eroomde> yeah, LOS up there with tuned dipoles would be significantly better, i'm sure
[23:23] <jcoxon> and we can play with the format
[23:23] <jcoxon> what do you think of the plan then?
[23:24] <eroomde> definitely worth it
[23:24] <jcoxon> do we just go for it
[23:24] <eroomde> and we could try it with some 1m dia balloons
[23:24] <eroomde> from chantry point
[23:25] <jcoxon> where do we get 1m balloons from?
[23:25] <Randomskk> would you use dipoles?
[23:26] <eroomde> 250 grammers maybe?
[23:26] <jcoxon> would need permission
[23:26] <Randomskk> xbees have some great antennas, someone xrayed one recently
[23:26] <Randomskk> http://blog.makezine.com/archive/2010/12/x-ray_xbee.html
[23:26] <eroomde> jcoxon: really?
[23:26] <eroomde> is it <1m for the entire flight?
[23:26] <jcoxon> yeah
[23:26] <eroomde> or just in controlled airpsace?
[23:27] <jcoxon> Small balloon' means a balloon of not more than two metres in any linear dimension at any stage of its flight,
[23:28] <solistice> sorry to be intruding your conversation, but I'm wondering if anyone could enlighten me about the regulations i have to go through in belgium
[23:28] <eroomde> there will be 36
[23:28] <eroomde> one for each member country
[23:28] <eroomde> and they will contradict each other
[23:28] <eroomde> but no matter, as long as everyone feels like they've got their bit
[23:29] <jcoxon> solistice, hehe, you'd need to contact your airspace regulator
[23:29] <jcoxon> it varies from country to country and i'm not sure anyone here is from belgium
[23:29] <eroomde> i need to work on the dough. back in about 15 mins
[23:29] <jcoxon> np
[23:30] <solistice> alright than,

[23:40] <iNatrium> jcoxon: throwing a party?
[23:41] <jcoxon> super-pressure balloons
[23:41] <jcoxon> :-p
[23:42] <iNatrium> how many would you need?
[23:42] <jcoxon> still to work out
[23:42] <SpeedEvil> http://www.balloons.co.uk/shop/uninflated-foil-balloons-80/singing-foil-balloons-335/
[23:42] <SpeedEvil> Alternative recovery methods!
[23:43] <iNatrium> you need to underinflate them rite...
[23:43] <jcoxon> iNatrium, yeah
[23:43] <iNatrium> for whatever altitude you want to reach
[23:43] <jcoxon> exactly
[23:43] <iNatrium> lol SpeedEvil
[23:44] <SpeedEvil> You need it so that at the altitude you want to hit the excess bouyancy when it hits that altitude and the balloon is fully inflated is not enough to burst it
[23:44] <SpeedEvil> which means carefully calculating, and probably quite a slow ascent
[23:44] <SpeedEvil> (or a leak)
[23:44] <jcoxon> SpeedEvil, agreed
[23:44] <SpeedEvil> yeah - I was commenting to iNatrium.
[23:44] <jcoxon> they question is also can you get enough lift
[23:44] <jcoxon> for the size
[23:45] <jcoxon> e.g. the balloons i got recently don't
[23:45] <jcoxon> they have ~5g of extra lift
[23:45] <SpeedEvil> with helium?
[23:45] <jcoxon> welll i suspect it wasn't pure He
[23:46] solistice (4a680490@gateway/web/freenode/ip. left irc: Quit: Page closed
[23:47] <jcoxon> just enough He to lift itself
[23:48] <eroomde> back

[23:48] <jcoxon> eroomde, big foil balloons

[23:48] <jcoxon> 91cm
[23:49] <eroomde> wow
[23:49] <eroomde> ideal
[23:50] <iNatrium> which colour?
[23:50] <jcoxon> iNatrium, that is important
[23:50] <iNatrium> 99 red balloons?
[23:51] <iNatrium> maybe something that reflects sunlight better
[23:51] <iNatrium> white
[23:52] <SpeedEvil> jcoxon: have you considered weighing it empty?
[23:52] <jcoxon> SpeedEvil, to work out the total lift?
[23:52] <SpeedEvil> yes
[23:52] <jcoxon> as in excess lift + balloon weight
[23:52] <jcoxon> then we can work out if it is pure?
[23:52] <SpeedEvil> And how much ift it'd have if you filled it with H2
[23:52] <SpeedEvil> H2
[23:52] <SpeedEvil> He I meant
[23:53] <jcoxon> will do that tomorrow morni
[23:53] <SpeedEvil> (though I have been looking at Zn anodes from ebay
[23:53] <jcoxon> right time for bed for me - on call this weekend
[23:53] <SpeedEvil> Good night!
[23:53] <jcoxon> did 13hrs today
[23:53] <jcoxon> was painful
