[00:13] <jgrahamc> StratHAB1 folks have tweeted that their payload was discovered by a shepherd who phoned them.
[00:13] <NigeyS> wow, shepherds have phones? :|
[00:14] <MNSP> so they do tend their flocks by night
[00:15] <NigeyS> whenever someone mentions shepherd i just get the image of a walking stick and a one piece cloth garment..lol
[00:15] <fsphil> not enough shepherds in yorkshire it seems
[00:16] <jgrahamc> My sister trained as a shepherd. Has the best behaved dog I have ever seen.
[00:16] <MNSP> well its good news for the StratHAB1 folks anyway

[00:19] <russss> ooh I like the sat coverage map - where does that data come from?
[00:19] <jgrahamc> It's a sheep dog.
[00:20] <NigeyS> russss, afaik that data is direct from orbcomms groundstations
[00:21] <NigeyS> jgrahamc, they are extremely obedient dogs, love them
[00:21] <russss> ah well there is this. http://www.orbcomm.com/Collateral/Documents/English-US/o11082.tle

[06:15] <natrium42> my brother's app just released
[06:15] <eroomde> it's a bit hairy as you have to keep it pointing into the wind and the winds can be weird around the moutains
[06:15] <natrium42> does it fly in a grid pattern automatically?
[06:16] <eroomde> it does in places where i'm happier to let it autopilot
[06:16] <natrium42> wow, nice piloting
[06:16] fsphil (~phil@2001:8b0:34:1:21f:c6ff:fe44:b25b) joined #highaltitude.
[06:16] <eroomde> but around the mountains i'm sticking with flying it myself for now
[06:17] <eroomde> still issues with gps co-ords and digital elevation maps using different co-ordinate systems and so on, meaning you have to besuper careful not to generate waypoints that are inside mountains
[06:17] <eroomde> oh i was thinking yeserday how much i want an image stab app for my phone
[06:17] <eroomde> might buy it!
[06:18] <natrium42> is there no danger that it will be blown off course if winds are too strong?
[06:18] <natrium42> i wish apple didn't screw up in-app purchase for some reason
[06:18] <natrium42> he has been calling them all day
[06:18] <eroomde> well the autpilot can deal with some wind, but the motor power to cross-sectional area ratio of the blimp is just tiny compared to, say, a quad copter
[06:18] <eroomde> so you have to be careful
[06:18] <natrium42> so it's only in demo mode right now

[06:23] <SamSilver> nice landing of the blimp
[06:23] <eroomde> impossible to recreate in the garage back at the avalnache institute, usually
[06:23] <eroomde> but always popping up after tracking up the the avalnache zone
[06:26] <eroomde> hairy landing! http://www.youtube.com/watch?v=N9Ec9fuy5zc
[06:27] <natrium42> eek
[06:28] <natrium42> what happens if you don't catch it?

[09:16] <fsphil> gps problem, launch aborted
[09:18] <fsphil> dont' think the satellite comms was working either
[09:18] <MNSP> Balls!
[09:19] <MNSP> thats a damn shame what with so many people chipping in their help and all
[09:20] <fsphil> yea I've never seen so many people involved with a launch, or observing.
[09:20] <fsphil> it's quite a big deal :)
[09:22] <MNSP> and you with your big pole too ;)
[09:22] <fsphil> oh yea -- still up :)
[09:22] <MNSP> but still, we live and learn - so hopefully they'll try again soon
[09:23] <fsphil> indeed -- the satellite thing is just a matter of timing I think, to make sure a few satellites are in view during launch
[09:23] <fsphil> hopefully the gps is just a matter of swapping it for a working one
[09:26] <MNSP> maybe by then I'll know enough to be useful - but lets not bank on it ;)

[09:33] <Laurenceb> launch scrubbed due to screwed RFI?
[09:34] <Laurenceb> never saw that one coming
[09:34] <fsphil> not even sure it was rfi
[09:35] <SpeedEvil> I thought it was a bad regulator.
[09:35] <SpeedEvil> Pity, anyway.
[09:37] <Laurenceb> ah

[09:39] grummund_ (~user@unaffiliated/grummund) left irc: Read error: Operation timed out
[09:39] <Laurenceb> im trying to send three bytes of data to a bluetooth modem
[09:39] <Laurenceb> sometimes i miss the last byte or very occasinally (~0.01%) the last two
[09:39] <Laurenceb> im wondering if maybe it could be explained by the wrong baud rate?
[09:40] <SpeedEvil> If your clock is >3% or so off, maybe
[09:40] <Laurenceb> as the bytes are consecutive, so pause, three bytes, pause three bytes etc
[09:40] <SpeedEvil> EMI?
[09:40] <Laurenceb> unlikely
[09:40] <SpeedEvil> I mean - on the line
[09:40] <Laurenceb> its an off the shelf device with hacked firmware
[09:40] <MNSP> Right chaps, its been emotional.. but I really better go and do some work ;)
[09:41] <Laurenceb> looks pretty well made - 8 layer sheilded pcb
[09:41] MNSP (c250db2c@gateway/web/freenode/ip.194.80.219.44) left irc: Quit: Page closed
[09:42] <Laurenceb> im using DMA to drive the UART, so the bytes should be sent straight after one another
[09:42] <Laurenceb> i guess if timing is slightly off, depending on how the bluetooth Rx UART is operating, it may lose framing after the first two bytes
[09:42] <Laurenceb> sounds feasible?
[09:42] <SpeedEvil> yes
[09:45] <Laurenceb> oddly i have an older firmware hacked version of the same hardware running ok
[09:45] <Laurenceb> i guess that could be explained by a different revision of the bluetooth
[09:46] <Laurenceb> it also depends on the data
[09:46] MoALTz (~no@92.18.11.137) joined #highaltitude.
[09:46] <Laurenceb> some data bytes i get about 1 packet in 10^6 failing, others 2% failing
[09:47] <Laurenceb> guess that could be the number of edges for the rx uart to sync to?
[09:49] <Laurenceb> ill have to identify the bluetooth ic and find how the bauds are derived
[09:49] <SpeedEvil> annoying.
[09:49] <SpeedEvil> I suppose checksumming isn't an option?
[09:50] <Laurenceb> maybe, but theres a lot of data
[09:50] <Laurenceb> its a medical datalogger powered by an Xscale
[09:50] <SpeedEvil> I see.
[09:51] <Laurenceb> probably easiest to fix whatever is wrong
[09:51] <Laurenceb> but 0.01% failing is ok, as the data is rather screwy anyway

[10:17] <fsphil> yea that's no fun
[10:35] <fsphil> will you have a tracking team going after it jgrahamc? or just a one-man job?
[10:36] grummund_ (~user@unaffiliated/grummund) joined #highaltitude.
[10:39] <jgrahamc> I'm going to rope in as many friends and family as possible. I'll be launching with the help of folks like eroomde and then following the balloon with my family in tow. Hoping to have a couple of friends and my parents to chase.
[10:39] <jgrahamc> Basically, I only want to launch when the wind is calm enough that we'll get a landing in Norfolk or Suffolk.
[10:44] <fsphil> yea -- hoping for something similar here too
[10:44] <fsphil> I've seen predictions that land it only a few km away -- can't see that happening too often though!
[10:44] <jonsowman> it usually doesn't :(
[10:44] <jgrahamc> I don't mind driving, but I'd like to avoid the sea.
[10:45] <jonsowman> Apex II was fairly good, about 30mi
[10:46] <fsphil> the first cirrus/hadie launch got about 25/30 miles
[10:46] <fsphil> was a nice drive
[10:47] <fsphil> I'm torn between staying at the launch site with the big yagi to receive data, or follow in the car with a small whip
[10:49] <jgrahamc> I'm bringing the Yagi, but have a little mag mount whip that I'm going to stick on the car.
[10:50] <fsphil> watson?
[10:51] <fsphil> the yagi is useful for direction finding too
[10:53] <jgrahamc> Not sure it's a Watson, got it second hand with a bunch of ham gear.

[19:14] <gb73d> my alarm was about to go off I woke up and thought I just cant get out of bed i was so tired
[19:14] <gb73d> least I aint missed anything !
[19:17] <NigeyS> hehe
[19:17] <NigeyS> disappointing to have scrubbed, but that's life in habing i guess
[19:20] <gb73d> oh yes onwards and hopefully upwards
[19:22] <NigeyS> indeed, i think the whitestar team deserve a good rest between now and then though, theyve really put in the hours

[19:40] <NigeyS> evening Kevin
[19:40] <Laurenceb> gb73d: meet don grainger?
[19:40] <gb73d> first time ive done anything in oxford
[19:41] <gb73d> no but I did spot Prof Alan Chapman on his bike
[19:41] <Laurenceb> or neil bowles?
[19:41] <gb73d> I was at the Clarendon lab, the parkj next door was full of students
[19:41] <Laurenceb> ah Clarendon
[19:41] <gb73d> the pitt rivers museum i popped in
[19:41] <Lunar_Lander> lol that reminds me of Doc Brown on his bike in BTTF II
[19:41] <gb73d> its fab
[19:42] <gb73d> going back w camera its allowed
[19:42] <Laurenceb> i did my undergrad there
[19:42] <Laurenceb> met quite a few of the main sat people
[19:43] <Laurenceb> not that they do a lot of satellite work there
[19:43] <Lunar_Lander> satellite?
[19:43] <Lunar_Lander> ah
[19:43] <Lunar_Lander> like the kettering school or do they build instruments and such things there?
[19:43] <gb73d> yeah i was at RMetS do its free open to all
[19:44] <gb73d> got a day at RAL solar montoring in May
[19:44] <Laurenceb> instruments
[19:44] <gb73d> putting all these on my cv
[19:44] <Laurenceb> i worked in the space instruments lab over the summer vac there one - loads of fun
[19:44] <Laurenceb> *once
[19:45] <gb73d> yeah the sats can measure wind speed, rainfall etc
[19:45] <Lunar_Lander> yeah
[19:45] <gb73d> was alot about algorithms
[19:45] <Lunar_Lander> wind speed
[19:45] <Lunar_Lander> how do they do it?
[19:45] <gb73d> post doc level
[19:45] <Lunar_Lander> Nimbus 6 did it by comparing data from balloons and buoys and stuff
[19:45] <gb73d> using big computers and a lot of cklever software
[19:46] <Lunar_Lander> the satellite received the data from those platforms
[19:46] <Lunar_Lander> yeah
[19:46] <Laurenceb> laser doppler is one way aiui
[19:46] <Lunar_Lander> but how do you measure wind from space?
[19:46] <Lunar_Lander> ah
[19:46] <gb73d> yeah was all aboit that data assimilation
[19:46] <Lunar_Lander> ah
[19:46] <gb73d> err backscatter of mircorwave signals is affected by wave height
[19:46] <Lunar_Lander> yeah
[19:46] <Lunar_Lander> that was the idea of SEASAT
[19:47] <Lunar_Lander> unfortunately it short circuited
[19:47] <gb73d> it was fantatsic day really high level
[19:47] <Lunar_Lander> btw, there are some crap theories that SEASAT was "killed"
[19:47] <gb73d> then i went out ands did 2 hoursa of geology at Reading
[19:47] <Lunar_Lander> cool
[19:47] <Lunar_Lander> did you find a fossil?
[19:47] <gb73d> was a long day
[19:47] <gb73d> only me !
[19:47] <Laurenceb> its also possible with reflected GPS
[19:47] <Lunar_Lander> yay
[19:48] <Lunar_Lander> yeah
[19:48] <Lunar_Lander> the REMAX balloon was supposed to test that
[19:48] <gb73d> yeah gps is in low microwave region
[19:48] <Laurenceb> hmm
[19:48] <Laurenceb> yeah i have a sige sampler - we could try that
[19:50] <gb73d> yeah I wonder if i couldf make a radiometer
[19:50] <Lunar_Lander> have a look at that: http://replay.waybackmachine.org/20030803102723/http://www.remax.com/sports/ballooning/science.html
[19:50] <Laurenceb> i meant to do that while i was at oxford, but never got round to it
[19:50] <Laurenceb> forgot about the idea completely
[19:54] <gb73d> i sea the sea state stuff interesting , no need for a onbaord microwave txer w gps

[19:57] <Laurenceb> hi natrium42
[19:59] <gb73d> ive always wanted to know how they use radiometers on soace craft to anaylyse the atmosphweric composition of planetary atmospheres
[19:59] <gb73d> im getting there
[20:00] <gb73d> everything emits radiation placnk law
[20:03] <gb73d> the backscatter effect could also be appiled to anaylysing the state of the ionosphere
[20:03] <gb73d> presumably
[20:05] <gb73d> they can only measure wind vectors from space in a limited range
[20:05] <gb73d> if its too fast the direction cannot be accurate
[20:06] <gb73d> its cutting edge stuff allright

[20:46] <fsphil> spiffy aurora video: http://vimeo.com/21294655
[20:46] <Lunar_Lander> yeah planetary balloons will be a challenge
[20:46] <Lunar_Lander> but on Venus they have functioned well already
[20:48] <SpeedEvil> Venus is cheating though.
[20:49] <SpeedEvil> On venus, you can skydive down to a safe (well, easily survivable) landing.
[20:49] <Lunar_Lander> you mean because you can inflate the balloon with water vapor?
[20:49] <Lunar_Lander> ah yeah
[20:49] <Lunar_Lander> Venera did that
[20:49] <SpeedEvil> (neglecting the toxic, hot atmosphere)
[20:49] <fsphil> the goggles will do nothing on venus
[20:50] <fsphil> it's a planet usually ignored -- you'd think with it being so close there'd be more interest
[20:51] <fsphil> I'm sure the challenges of surviving on the surface can be overcome
[20:52] <Lunar_Lander> yeah I agree
[20:53] <SpeedEvil> The other problem is you have crap energy sources on the surface.
[20:53] <SpeedEvil> You're left with windpower.
[20:53] <fsphil> yea, overcast skies
[20:53] <SpeedEvil> Which is at best awkward.
[20:53] <SpeedEvil> Especially at that temperature.
[20:57] <natrium42> ur akward
[20:58] <fsphil> the next mars rover is nuclear powered, that could be an option too

[21:00] <SpeedEvil> Nuclear is indeed an option.
[21:00] <Lunar_Lander> I mean for the ALSEP stations
[21:00] <SpeedEvil> It's especially not-that-bad on venus, in principle.
[21:01] <Lunar_Lander> and RTGs can reenter

[22:04] <fsphil> postage costs to europe would suck :)
[22:05] <Laurenceb> anyone here used bluetooth serial modules with ubuntu?
[22:08] <Lunar_Lander> fsphil they could make it a DIY one
[22:08] <Lunar_Lander> i.e. disassemble it so that it fits a smaller package

[22:15] <Laurenceb> ive got it talking ok... trying to make it easier
[22:15] <Laurenceb> atm sudo rfcomm --raw connect 4

[22:56] <NigeyS> Thanks Kevin :D
[22:57] <Lunar_Lander> and jaffa cakes are cool fsphil
[22:57] <Lunar_Lander> I just had a chocolate orange from austria
[22:57] <fsphil> excellent
[22:57] <Lunar_Lander> they taste almost the same
[22:57] <Lunar_Lander> and now good night :)
[22:57] <fsphil> g'night Lunar_Lander

[23:07] <SpeedEvil> It's now 3 in indiana?
[23:08] <SpeedEvil> I wonder if the new IR telescope whos name I've forgotten will lead to more refinement.
[23:08] <SpeedEvil> ^space
[23:08] <fsphil> spitzer?
[23:08] <SpeedEvil> Hipparcos?

[23:08] <SpeedEvil> naah
[23:09] <SpeedEvil> (not hipparcos)
[23:09] <NigeyS> 73.8 KPS per megaparsec =/- 3.3%
[23:09] <SpeedEvil> Not spizer
[23:09] <SpeedEvil> launched recently
[23:09] <NigeyS> wise ?
[23:09] <SpeedEvil> Herschel.
[23:09] <SpeedEvil> The Herschel Space Observatory is a European Space Agency space observatory sensitive to the far infrared and submillimetre wavebands. It is the largest space telescope ever launched, carrying a single mirror of 3.5 meter in diameter.[1][2][3]
[23:10] <NigeyS> ah yes herschel
[23:10] <SpeedEvil> There is work being done on even longer wavelength and lower temp sensitive version.
[23:11] <NigeyS> sweet!
[23:11] <SpeedEvil> I can see no sensitivities in human friendly units.
[23:11] <NigeyS> theres a new group of mm telescopes due to be ready soon to isnt there ? ... ground based
[23:11] Action: SpeedEvil ponders adding 'can detect a sperm whale at a distance of...'
[23:11] <NigeyS> lol
[23:12] <SpeedEvil> WAter is basically really annoying in these wavebands
[23:12] <SpeedEvil> As are other gasses.
[23:12] <NigeyS> true
[23:12] <fsphil> yea tis pretty opaque between radio and light
[23:12] <NigeyS> water fog!

[23:16] <SpeedEvil> Kepler is outputting fun stuff too.

[23:16] <NigeyS> ALMA!
[23:17] <SpeedEvil> I do wonder what's being missed because kepler decimates the data so hugely
[23:18] <NigeyS> quite alot i'd imagine
