[08:29] <SpikeUK> Would I be right to say that the *only* way to programme a Robostix is via an external lump of hardware?
[08:29] <jcoxon> hehe
[08:30] <jcoxon> ummm you can program it from the gumstix i think
[08:30] jnd (n=jenda@unaffiliated/jnd) joined #highaltitude.
[08:30] <jcoxon> i've never really looked into it
[08:32] <SpikeUK> jcoxon - I'm trying to prog it standalone - without the gumstix (Verdex etc)

[12:13] <jcoxon> actually i'll still be in Cam
[12:13] <jcoxon> but
[12:14] <jcoxon> i might be able to set up some magic
[12:14] <fnoble> oooh magic
[12:14] <jcoxon> is there a chance you could record me some data so i can check that i'm decoding it fine
[12:17] <fnoble> jcoxon, not in the lab atm
[12:17] <fnoble> can do a bit later iuw
[12:17] <jcoxon> no worries
[12:17] <fnoble> but trutty decodes it fine
[12:17] <jcoxon> its not that
[12:17] <jcoxon> its the next step
[12:18] <fnoble> ok, i have some text that was the output of the decode
[12:18] <jcoxon> oh actually so do i
[12:30] <jcoxon> fnoble, should it be USB or LSB on the radio?

[12:39] <SpikeUK> 3am? You're crazy, you too!
[12:39] <jcoxon> not the first time they've done a night launch!
[12:41] <edmoore> It means I can be at work in time
[12:41] <jcoxon> is anyone going to be online at that time of morning
[12:41] <jcoxon> (i'm not :-p

[12:41] <edmoore> the internet never sleeps, jcoxon
[12:41] <jcoxon> haha
[12:41] <jcoxon> and would like to help track
[12:41] <jcoxon> ?
[12:41] <jcoxon> just need to be on the net
[12:41] <SpikeUK> Really? Wx forecast looks good - not much in the way of wind. Me - If I set me alarm
[12:42] Action: jcoxon glues a wheel to a servo attached to an arduino which is attached by a belt to his radio tuning dial + a webcam streaming + truetty and tracking...
[12:42] <edmoore> conditions are good
[12:42] <edmoore> some cloud too, which makes for pretty pictures
[12:43] <SpikeUK> jcoxon - I'll be about
[12:43] <edmoore> can we get the tracker working?
[12:43] <edmoore> hop on ustream again?
[12:44] <jcoxon> i should be able to get online tracking up and running
[12:44] <edmoore> amazing
[12:45] <edmoore> ok, need somewhere to dump raw data
[12:45] <edmoore> so the UMSF geneii can do their thing
[12:45] <edmoore> if they want to
[12:51] <SpikeUK> jcoxon - I'll be awake if I can help with owt?
[12:56] <jcoxon> excellent
[12:56] <jcoxon> give me a few hours and i should have something set up
[13:00] <SpikeUK> jcoxon - I'll catch you later

[14:22] <edmoore> robert1971: hello!
[14:22] <edmoore> we're launching tomorrow
[14:22] <robert1971> Wow CU
[14:22] <robert1971> ?
[14:23] <edmoore> yeah
[14:23] <edmoore> and Doug
[14:23] <robert1971> Where from?
[14:23] <edmoore> Nova 8 / HAPS-D is the title
[14:23] <edmoore> Churchill College again
[14:23] <edmoore> D for dawn
[14:23] <edmoore> want to get the sun as it emerges over the curvature of the earth
[14:23] <robert1971> what time's launch then?
[14:24] <robert1971> I many come down
[14:24] <robert1971> may*
[14:24] <fnoble> robert1971, you will have to be up late
[14:24] <edmoore> about 4am
[14:24] <fnoble> will be launching just after 3am
[14:24] <SpikeUK> "D" = "Dead early"
[14:24] <edmoore> I would have thought nearer 4
[14:24] <fnoble> yeah, well we'll work it out
[14:24] <robert1971> Sounds good I can be back @ work for lunch
[14:24] <edmoore> based on the following napkin logic
[14:24] <edmoore> we calculated 3.20am for nova 7 and sunrise on the ground was 5:09
[14:25] <edmoore> now sunrise on the ground is 5:57
[14:25] <fnoble> yup ok, hadnt got round to checking the sunrise times yet
[14:25] <edmoore> but it is worth recalculating properly, obv
[14:25] <edmoore> is Steven coming?
[14:25] <fnoble> edmoore, do you want to recalc it if your not busy?
[14:25] <fnoble> no, i dont think so
[14:26] <jcoxon> right i've got a servo attached to the tuning dial
[14:26] <fnoble> jcoxon, hehe
[14:26] <robert1971> R U going to have access to the bar at that time or are you going to be based in the carpark?
[14:26] <jcoxon> next to add a webcam to view the screen
[14:26] <edmoore> I am very busy. My left hand is trying to move some rocks
[14:26] <edmoore> but i will do it in about 1hr
[14:26] <edmoore> software rocks, that is
[14:26] <edmoore> robert1971: we'll be in the bar
[14:26] <fnoble> robert1971, the bar will be acessable
[14:26] <edmoore> do the set-up
[14:27] <edmoore> maybe stream live t'internet again
[14:27] <edmoore> then head out
[14:27] <edmoore> I am so glad I won't have to go to the other side of Nottingham again
[14:28] <fnoble> yup
[14:28] <robert1971> OK I think I'm up for it will get an early night tonight and then come down for 3:30am at the bar
[14:28] <fnoble> the dynamic lading prediction should be working so the recovery could be quite direct
[14:28] <edmoore> robert1971: cool
[14:28] <edmoore> doug is arriving at 2am
[14:28] <fnoble> robert1971, awesome
[14:28] <edmoore> 2.30, even
[14:28] <edmoore> that's probs when we'll establish outselves in the bar
[14:29] <edmoore> then head out to the field about once we're ready
[14:29] <edmoore> will probably be already out by 3.30
[14:29] <robert1971> Ok I may get there a bit sooner. Still knackered from being up till 2 this morning and then getting up with the kids at 7am
[14:30] <robert1971> I'll try and get some sleep this afternoon.

[14:38] <edmoore> wouldn't go as far as personality
[14:39] <edmoore> especially at 3am
[14:39] <jcoxon> hehe
[14:39] <edmoore> jcoxon: you're in cam tonight aren't you?
[14:39] <jcoxon> yup
[14:39] <robert1971> Do I need to bring anything other than laptops and some coffee
[14:40] <edmoore> that'll be all you need
[14:40] <fnoble> robert1971, an extra radio is always good if you have one
[14:40] <edmoore> oh yes, was about to say that
[14:41] <edmoore> looks like we're on 2 chase cars anyway
[14:41] <fnoble> yup
[14:41] <edmoore> doug is being some walkie-talkie radios
[14:41] <edmoore> to comm between cars
[14:41] <fnoble> nice
[14:41] <edmoore> bringing*
[14:41] <edmoore> if you have mobile internet, that's a big plus
[14:41] <fnoble> robert1971, a handheld gps might also come in handy
[14:41] <robert1971> I could do a bit of the media stuff if you want. Keep the information rolling on highaltitude99. It went a bit quiet on Sunday
[14:42] <fnoble> again if you have one lying around
[14:42] <edmoore> I'm sure people online will want to know what's happening from the ground
[14:42] <edmoore> yeah
[14:42] <edmoore> robert1971: things tend to unless they go right :)
[14:42] <fnoble> brb
[14:42] <edmoore> robert1971: that'd be fantastic then if you're willing to throw the odd min at that
[14:43] <robert1971> I'll drag a video and camera along too. See what I can do about getting some initial stuff up quickly.
[14:44] <robert1971> I don't have a radio :( but I may be able to lay my hands on a handheld gps.
[14:44] <jcoxon> map and compass!
[14:44] <edmoore> oh yes!
[14:44] <edmoore> tho we have no becon
[14:44] <jcoxon> lol do you want one :-p
[14:45] <robert1971> Google map and compass? I do have a compass here next to me :)
[14:45] <edmoore> robert1971: the wireless in the bar is a bit creeky for uploading
[14:45] <edmoore> no, a road map
[14:45] <edmoore> though if you have wireless net, sorted
[14:45] <edmoore> we couldn't get it on enough to use GM effectively on sun
[14:45] <robert1971> I'll see what the USB key from vodaphone can do. It's got a 3GB limit on it
[14:45] <edmoore> and foxhunting just feels right with a pencip, map and compass

[14:55] <edmoore> yep
[14:55] <edmoore> always helps
[14:55] <edmoore> though we'll have a few too
[14:55] <robert1971> I have GPS a as I have speedtrap detector that spews nema out of the serial port
[14:56] <jcoxon> right
[14:56] <jcoxon> http://www.ustream.tv/channel/ukhas-balloon-launch
[14:59] <jcoxon> tis my internet controlled radio
[15:01] <robert1971> bit blured
[15:01] <jcoxon> you should be able to just read it
[15:02] <robert1971> 46390
[15:02] <jcoxon> oh i've been moving it a bit
[15:03] <jcoxon> right now its 46610
[15:03] <jcoxon> which is 434.6610
[15:03] <robert1971> yep
[15:03] <jcoxon> Mhz
[15:04] <jcoxon> next to make the arduino accessible
[15:04] <robert1971> I gess there's no point having a radio if there is no beacon. Is that correct?
[15:05] <robert1971> guess*
[15:06] <jcoxon> they'll be telemetry from the balloon
[15:06] <jcoxon> in the form of rtty
[15:07] <jcoxon> robert1971, thats clearer now?
[15:07] <robert1971> Loads
[15:08] <jcoxon> just had to position my light a bit better
[15:08] <robert1971> 4.650.0
[15:08] <jcoxon> yup
[15:08] <jcoxon> good
[15:09] <jcoxon> the beacon is really jsut a backup, the main radio will keep us up to date
[15:09] <robert1971> Is that a chemistry book behind the radio?
[15:10] <robert1971> Opps the radio is off
[15:11] <jcoxon> oh i turned it off
[15:11] <robert1971> Could I pick up a radio today, or are they a bit pricy
[15:11] <jcoxon> its actually a poetry book
[15:11] <jcoxon> nah they are pricey
[15:11] <jcoxon> and hte best ones are difficult to find
[15:11] <robert1971> I got the try
[15:11] <jcoxon> don't worry about it
[15:12] <robert1971> cool... I'll leave that to some research later. I saw an Icon one that looked nice
[15:21] <edmoore> £150 you're talking
[15:21] <edmoore> for the one that we all use
[15:21] <edmoore> it's pretty sensitive
[15:21] <edmoore> jcoxon:
[15:21] <edmoore> could you do anything with 2.4ghz kit?
[15:21] <jcoxon> ?
[15:22] <jcoxon> which kit?
[15:27] <edmoore> oh sorry
[15:27] <edmoore> i mean
[15:28] <edmoore> transmitting at 2.4ghz
[15:28] <edmoore> for sstv
[15:28] <jcoxon> the problem would be receiving i think
[15:28] <jcoxon> steve and i think we might have cracked sstv
[15:28] <jcoxon> as we can now do it on ssb from the gumstix
[15:28] <edmoore> well, thinking in terms of higher gain TX antennas
[15:32] <jcoxon> definitely an option

[15:41] <ShellEvil> What's written on the package?
[15:42] <ShellEvil> Some sort of 'if found...' ?
[15:43] <fnoble> ShellEvil, yes
[15:43] <fnoble> it says "harmless scientific experiment"
[15:43] <fnoble> :)
[15:46] <ShellEvil> 'Not a bomb - really'.
[15:46] <ShellEvil> :)
[15:53] <robert1971> edmoore: 150 quid sounds reasonable
[15:53] <edmoore> it's a good investment
[15:53] <edmoore> it's a quality bit of kit

[22:58] <edmoore> in the basement
[22:58] <edmoore> on someone else's laptop
[22:58] <doug_ellison> Ahh
[22:59] <doug_ellison> Well - I have a housing just about finished - the script is done ( and tested during sunset )
[22:59] <edmoore> success?
[22:59] <doug_ellison> It was perfect. 3 hrs filled 2.6 gig of the 3.6 gig on the card
[22:59] <doug_ellison> 20s 640 x 480 movies, and sets of 8 stills.
[22:59] <edmoore> ok, i need to drive iain to his house to get some sd cards. I will hand you over to fergus
[22:59] <edmoore> did it expose ok on the sunset?
[23:00] <doug_ellison> it did very well actualy
[23:00] <edmoore> (ed still)
[23:00] <edmoore> brill
[23:00] <edmoore> promising then
[23:00] <doug_ellison> after sunset you can see the lights come on in peoples windows and their shadows against their curtains etc

[23:02] <edmoore> do you have any spare SD cards also?
[23:02] <doug_ellison> About the script I have on the A560....and exactly that
[23:02] <doug_ellison> I have a 4gb - I could set it up with the exact same script if you want
[23:03] <doug_ellison> or some other script ( just stills, just vids - whatever floats your boat)
[23:03] <edmoore> Ok. we ned 2 max for these crap-cams
[23:03] <edmoore> we're ok for the chdks
[23:03] <edmoore> maybe the sd is under one of these massive piles of shit
[23:03] <doug_ellison> I have a 2 gig somewhere I think as well.
[23:03] <doug_ellison> Crapcams don't like SDHC cards I presume
[23:06] <edmoore> indeed
[23:06] <edmoore> ok, off

[23:14] <fnoble> yeah ive got your CHDK on it and made a slightly modded version of your script
[23:14] <fnoble> although from your recent email i may nick the newer script you have prepared
[23:14] <fnoble> sounds like a better plan
[23:14] <doug_ellison> :)
[23:15] <doug_ellison> Do you hav a 4 gb card for the 560 - that's what that script will need
[23:15] <fnoble> yeah we have a new 4gig
[23:16] <doug_ellison> Grat.

[23:17] <fnoble> we will find a way to fit it on
[23:17] <fnoble> all of the top is free
[23:17] <doug_ellison> I will be rounding off the corners a bit, just so it can't tangle on anything
[23:17] <iNatrium> I am mobile ATM, anything urgent?
[23:17] <fnoble> ok cool
[23:18] <fnoble> iNatrium: nope, just asking if you wanted to play with james rig during the launch?
[23:18] <iNatrium> Launch I'd still on?
[23:18] <fnoble> yeah
[23:18] <fnoble> for 3:30 GMT+1

[23:26] <fnoble> maybe thats best then, can just plug it in and go

[23:36] <fnoble> badger + 2x premiers + 1x our a560 + dougs HAPS system from last time
[23:36] <Laurenceb> ha
[23:36] <fnoble> so 4 cameras :)
[23:36] <Laurenceb> how are you triggering the premiers?
[23:37] <Laurenceb> gpio off the badger?
[23:37] <fnoble> from the badger
[23:37] <fnoble> yup
[23:37] <Laurenceb> I see
[23:37] <Laurenceb> got the futaba S3152 today :D
[23:37] <Laurenceb> it looks good, I just need to work out a winch arrangement with it
[23:38] <Laurenceb> fnoble: I'm thinking of using badger for a rogallo, I'm getting a bit limited with an AVR
[23:38] <Laurenceb> it really needs dynamic control loops to go above 8Km, and my AVR doesnt have the RAM
[23:39] <Laurenceb> what do you have broken out on badger?
[23:39] <Laurenceb> spi? i2c?
[23:39] doug_ellison (n=djelliso@87-127-121-8.no-dns-yet.enta.net) joined #highaltitude.
[23:39] <Laurenceb> hi
[23:39] <SpeedEvil> Laurenceb: the answer is clear.
[23:39] <SpeedEvil> Laurenceb: AVR32.
[23:39] <Laurenceb> ha
[23:39] <Laurenceb> its a very very cool processor
[23:40] <SpeedEvil> Laurenceb: though tincantools offering looks like fun.
[23:40] <Laurenceb> but also pretty complex
[23:40] <Laurenceb> avr32 linux makes it easy, but then real time control is hard
[23:40] <SpeedEvil> hardware pwm units IIRC
[23:40] <Laurenceb> even I could compile a kernel :P
[23:40] <SpeedEvil> I know there are two on the tincantools thing
[23:40] Action: Laurenceb is a linux noob
[23:41] <Laurenceb> sure, I'm using hardware pwm atm
[23:41] <G8KHW> night - guys best of luck with tomorrow mornings flight
[23:41] <Laurenceb> but the kalman filter loop timing ect needs to be very tight
[23:41] <Laurenceb> rocketboy
[23:41] <Laurenceb> quick Q
[23:41] <fnoble> Laurenceb: where are you going to source a badger from?
[23:41] <Laurenceb> I have alu foil tape from screwfix
[23:42] <Laurenceb> fnoble: you :P
[23:42] <fnoble> hehe
[23:42] <fnoble> well you should wait for v2
[23:42] <Laurenceb> and was thinking of covering the bottom of the payload
[23:42] <fnoble> v1.1 is not ready for the prime time
[23:42] <fnoble> ok, over to ed
[23:42] <fnoble> need to get some code onto the badger
[23:43] Nick change: fnoble -> edmoore
[23:43] <G8KHW> and the Q is?
[23:43] <edmoore> tag team
[23:43] <Laurenceb> sorry
[23:43] <Laurenceb> dragged off
[23:43] <Laurenceb> yes, what will that do to the 434 MHz
[23:44] <Laurenceb> if say there is a whip ant on the bottom
[23:44] <G8KHW> well the answe is yes and overlap it
[23:44] <Laurenceb> will it halp shield the tronics?
[23:44] <Laurenceb> and direct the rf down?
[23:44] <Laurenceb> edmoore: on the asus?
[23:45] <Laurenceb> edmoore: squinting? :-P
[23:45] <G8KHW> sheld the tronics from 10mw of RF?
[23:45] <Laurenceb> hehe
[23:45] <Laurenceb> ok, well is it a good idea or bad with regard to the rf?
[23:45] <Laurenceb> the enclosure is about 20cm long
[23:45] <SpeedEvil> Laurenceb: tincantools has a 200MHz ARM - I'm guessing kalman CPU load wouldn't be a problem :)
[23:45] <SpeedEvil> Shielding is unfortunately a horribly complex issue.
[23:46] <Laurenceb> yeah
[23:46] <Laurenceb> oh well it gives some scuff protection and helps to ensure laminar flow
[23:46] <G8KHW> well its a good idea
[23:46] <Laurenceb> which were my main thoughts
[23:46] <SpeedEvil> It's much like trying to make a quiet room when all you have is crisp-packets and bells as construction material :)
[23:47] <Laurenceb> ok, good then :D
[23:47] <Laurenceb> haha
[23:47] <Laurenceb> edmoore: I was thinking of putting my prarafoil/rogallo code on a badger
[23:48] <Laurenceb> does it have spi brocken out?
[23:48] <Laurenceb> *broken
[23:48] <Laurenceb> and how is the SD card interfaced? is there FAT?

[23:51] <edmoore> back
[23:51] <edmoore> Laurenceb: were you now?
[23:52] <edmoore> yes, it has broken out spi, i2c, rs232
[23:52] <edmoore> etc
[23:54] <edmoore> and it is fat
[23:55] <edmoore> we have decided that because RTTY sounds so 1970s cold-war film, we need a mechanical teletpye machine
[23:55] <edmoore> for the chase car
[23:55] <edmoore> one of those typewriter things
[23:55] <doug_ellison> Like Grandstand
[23:56] <edmoore> Michael Caine can operate it
