[07:44] <Shuffty> Morning.. website says"DEFINITELY"... :-)
[07:44] <Shuffty> So, more than likely!
[07:45] <Upu> definitely is good
[07:48] <fsphil> it's not quite absolutely, but close enough
[07:48] <Shuffty> lol
[07:49] <Shuffty> I'm excited, but the chances of me hearing anything this far away have to be slim to none...
[07:49] <fsphil> 555km has been done, though that was at 50 baud
[07:50] <Shuffty> What is this one at - 100 baud?
[07:50] <fsphil> yep
[07:51] <jonsowman> I'll clear the tracker
[07:52] <jonsowman> there we go :)
[07:53] <Upu> I'll take an hour or so off work see if I can recieve anything

[08:53] <Upu> jonsowman if my iphone chase car tracker app updates to the server every 15 secs is that too frequent ?
[08:54] <earthshine> Anyone use Arduino chips in their flight computers?
[08:54] <Upu> yeah
[08:55] <Upu> well its an ATMEGA
[08:55] <Upu> effectively an Arduino
[08:55] <earthshine> Do you use the Arduino bootloader?
[08:55] <Upu> yes
[08:55] <earthshine> so it's an Arduino
[08:55] <earthshine> What GPS library do you use?
[08:55] <Upu> I just lifted the chip out of an Ardunio board
[08:55] <Upu> I don't
[08:55] <Upu> just my own
[08:55] <earthshine> What do you use to parse the NMEA strings?
[08:56] <Upu> 1 sec let me check
[08:56] <Upu> been a while
[08:57] <Upu> http://pastebin.com/zfAjdrwM
[08:59] <chembrow> I use the TinyGPS library from the UKHAS wiki
[08:59] <earthshine> chembrow: i've tried that with limited success
[08:59] <earthshine> Upu: thanks for that
[08:59] <chembrow> what didn't work?
[09:00] <Upu> RTTY bits from Rob Harrison
[09:00] <earthshine> chembrow: valid NMEA strings in but TinyGPS unable to parse data correctly
[09:00] <earthshine> i'll have another play this weekend
[09:00] <chembrow> the issue I had was with it not grabbing entire NMEA strings.
[09:01] <earthshine> may be my problem too
[09:01] <chembrow> turned out to be an issue with running at baud above 4800 and it clashing with a timer I had running
[09:01] <chembrow> took a VERY long time to debug
[09:01] <chembrow> I had to disable the timer when reading the GPS, and it also failed if I tried to echo the contents of the software serial to the hardware (for debug)
[09:02] <chembrow> worked fine on a regular 4800bps GPS. only failed on the GPSbee @ 9600bps
[09:02] <chembrow> wasn't an issue with the library so much as an issue with software serial
[09:02] <earthshine> strange
[09:03] <earthshine> Do you use IDE 0022 ?
[09:03] <chembrow> yes. and 0018 too, which I developed the original code on
[09:03] <earthshine> But it all works under 0022 ?
[09:03] <earthshine> Jcoxon said that something was broken with software serial under 0022
[09:04] <chembrow> it does now that I disable the timer when reading GPS. I have a 50hz timer to do control the ntx2. disabling that during the GPS read and it works fine
[09:04] <chembrow> I used this library to control the timer: http://www.arduino.cc/playground/Main/MsTimer2
[09:05] <earthshine> cool
[09:06] <chembrow> next time I'll try to figure a way to control multiple devices from the hardware uart
[09:06] <chembrow> or use an arduino mega
[09:10] <earthshine> chembrow: Done a launch yet ?
[09:12] <chembrow> not yet. hoping to do it mid-May. The payload is ready, apart from trying a long range test. Just need a free weekend to launch
[09:13] <chembrow> was hoping to do it over Easter, but I've been delegated decorating duties instead :(
[09:13] <earthshine> DOH!
[09:14] <fsphil> this launch is on 434.650 yea?
[09:15] <chembrow> according to the wiki it is

[09:17] <Hibby> Morning all
[09:17] <gm8oti> dl-fldigi gurus - I'm getting a "curl ... couldn't resolve host name" when it tries to upload my ident to spacenear.us. Any ideas?
[09:19] <Hibby> check your DNS
[09:19] <gm8oti> Hibby, other stuff is resolving OK in the web browser
[09:20] <fsphil> is robertharrison.org resolving ok?
[09:20] <gm8oti> fsphil yes I can ping it
[09:20] <fsphil> hmms
[09:21] <fsphil> in the configuration window, is the server set to robertharrison.org?
[09:21] <gm8oti> fsphil which config window?
[09:22] <fsphil> in dl-fldigi .. there's an option somewhere, I don't have a copy handy so I can't say where
[09:22] <fsphil> it's the last tab in the configuration window

[10:34] <fsphil> the payload xml is expecting SKYPOD, the signal is transmitting skypod
[10:34] <fsphil> change this in the payload configuration dialog
[10:35] <Hibby> SpeedEvil: it's an unusual string I suspec tthe server may be struggling with
[10:36] <Hibby> Graham_G3VZV: I hear a rumour you're coming up to see us next week?
[10:36] UpuMobile (UpuMobile@82.219.244.11) joined #highaltitude.
[10:36] <UpuMobile> hola
[10:37] <UpuMobile> Are we in the air ?
[10:37] <SpeedEvil> Looks like it's ~90km/h
[10:37] <gm8oti> Hibby detectable in Edinburgh - too noisy yet (and behind buildings!)
[10:37] <SpeedEvil> Measuring one on the ground
[10:37] <Graham_G3VZV> Hibby: Yes Monday afternoon or Tuesday morning - your choice and I will then go to CS in the other "window"...which would be best for you??
[10:37] <Hibby> UpuMobile: yes indeed.
[10:37] <UpuMobile> damn who launches balloons on time meh!
[10:37] <Hibby> Graham_G3VZV: will check with derek when he pops his head around the door :)
[10:38] <Hibby> gm8oti: I've heard it from ~200m, but this is why: http://db.tt/0DU03mf
[10:38] <jgrahamc> What antenna are you using Hibby?
[10:38] <Hibby> jgrahamc: see pic^^
[10:38] <UpuMobile> Just sat at the Audi dealer getting new tyres will try get up as soon as I can
[10:39] <jgrahamc> Nice Hibby
[10:39] <Hibby> one of my undergrad slaves on install day :p
[10:39] <fsphil> d'oh!
[10:40] <UpuMobile> you got Skypod yet fsphil ?
[10:40] <fsphil> a lovely signal here UpuMobile
[10:40] <UpuMobile> kk
[10:40] <fsphil> though the payload XML is setup wrong
[10:40] <gm8oti> getting data now but not full lines yet
[10:40] <fsphil> it's $$skypod, the xml is saying $$SKYPOD
[10:40] <fsphil> tis case sensitive
[10:41] <UpuMobile> Annoyingly I've left my antenna at work so I have to go back there before I can get listening
[10:41] <Hibby> fsphil: not caused me any problems? Equally, mine appears to be in lowercase
[10:41] <fsphil> hmms
[10:41] <fsphil> it could be something I've done then :)
[10:41] <fsphil> but if anyone finds they're receiving good strings but the bar isn't turning green (or even red) let me know
[10:43] <fsphil> much more stable signal than the last one
[10:44] <fsphil> annoyingly being at work I can't hear it
[10:45] <GM4JTJ> i'm getting every string and the bar is turning green..sadly no link to internet from shack.
[10:46] <UpuMobile> the speed of 8520km/hour is impressive

[10:46] <fsphil> lol
[10:47] <fsphil> parachute icon?
[10:47] <SpeedEvil> It's not implausible that it's 100* that - it was doing about 90 when i measured it.
[10:48] <MrCraig> As expected, no reception in the midlands on a very unsuitable antenna - except something that may be optimistic thinking in the noise.
[10:48] <SpeedEvil> You should I think have line of sight - just - by now
[10:49] <chembrow> MrCraig I can never get a signal on a Cambridge launch until it hits about 15k here in Stoke
[10:49] <Hibby> anyone else hearing qrm?
[10:50] <Hibby> or is that glasgow based?
[10:50] <MrCraig> chembrow: yeah I think I can hear something now - but I'm still waiting on a cable to use the directional, so I'm listening on a small whip - it's far too noisey
[10:50] <fsphil> it's a pretty quick ascent
[10:50] <Hibby> and it's gone
[10:50] <fsphil> oddly little QRM here
[10:50] <gm8oti> Hibby no qrm here
[10:50] <fsphil> 13km already
[10:50] <Hibby> aye, it was specced at 8m/s
[10:51] <chembrow> MrCraig whereabouts are you based?
[10:51] <Graham_G3VZV> dont forget the frequency is also used as an input to number repeaters around the UK so some QRM might be expected:)
[10:51] SpikeUK (d0331fa2@pdpc/supporter/monthlybyte/spikeuk) joined #highaltitude.
[10:52] <fsphil> some fading now
[10:52] <Hibby> yeah, im getting that too
[10:52] <MrCraig> chembrow: coventry
[10:52] <Hibby> first red string
[10:52] <fsphil> my dial frequency is 434.652
[10:52] <MrCraig> chembrow: and I am getting something, which I think is pretty amazing.
[10:52] <chembrow> MrCraig I'd say so. wish I was at home so I could join in :(
[10:53] <fsphil> 14km woo :)
[10:53] <Hibby> back in the green
[10:53] <gm8oti> nice data here but sadly dl-fldigi isn't sending it in :-(
[10:53] <Graham_G3VZV> ok signal S3 here now in Milton Keynes some QSB
[10:53] <fsphil> same here -- payload must have hit some turbulance
[10:53] <fsphil> gm8oti, still the problem with curl?
[10:54] <fsphil> fading again -- 14.5km
[10:54] <Hibby> back in the green
[10:54] <gm8oti> fsphil no it finally got a line from me so that's not it
[10:54] <Hibby> it's a jpole hanging down, so that may cause some issues
[10:55] <fsphil> shift has dropped from 630hz to 600hz

[10:56] <fsphil> gm8oti, is the bar at the top changing colour?
[10:57] <fsphil> the shift varies with temperature usually
[10:57] <gm8oti> fsphil no
[10:57] <chembrow> fsphil how do you tell what the shift actually is?
[10:58] Guest86958 (56b2a4f5@gateway/web/freenode/ip.86.178.164.245) left irc: Client Quit
[10:58] <fsphil> gm8oti, go into the payload configuration page, and change "SKYPOD" to "skypod"
[10:58] <fsphil> chembrow, just adjust it until it matches
[10:59] <fsphil> (configure -> dl client -> payload)
[10:59] <chembrow> I thought you could only choose from the drop down list? though that might have been in an older version
[10:59] <fsphil> yea older versions had a list -- new version still has that, but also a custom option
[10:59] <gm8oti> fsphil ahhhhh!

[10:59] <fsphil> excellent
[10:59] <fsphil> so it's not just me .. odd
[11:00] <GM4JTJ> Morning dave
[11:00] <fsphil> good decode that time too here -- getting a lot more checksum fails now
[11:00] <Graham_G3VZV> I believe the wavy red vertical frequency line is maybe doppler cuased by the payload swinging rapidly back and forth
[11:01] <fsphil> would the doppler effect be that prominent?
[11:02] <Graham_G3VZV> the jury is out on that but if not then what:)?
[11:02] <UpuMobile> thats going up quickly
[11:02] <Hibby> Graham_G3VZV: it's entirely possible that it's the heater turning on and off
[11:02] <fsphil> power supply could be oscillating
[11:03] <MrCraig> cr*p - my antenna cable just arrived. It appears there may have been some confusion between 5M and 0.5M
[11:03] <fsphil> !!
[11:03] <Hibby> battery voltage is roughly 1/2
[11:04] <DaveFEV> >JTJ Hi Jon Windy up there?
[11:04] <gm8oti> fsphil looked back at debug output - curl problem still there :-(
[11:05] <fsphil> nuts
[11:05] <jgrahamc> Who is G4FEV?
[11:05] <fsphil> it must be the version
[11:06] <gm8oti> fsphil - yeh, will try to fix for next time
[11:06] <Hibby> parachute icon much?!
[11:06] <fsphil> I've only tested it on fedora 12+
[11:06] <Hibby> looks like it's hit loads of turbulance there, look at the path and ascent!
[11:07] <gm8oti> fsphil don't know if ye olde laptoppe is capable of that!
[11:07] <fsphil> lol
[11:07] <Hibby> gm8oti: try something like mint lxde then

[11:08] <gm8oti> Hibby yes, there are plenty options - I use this for other stuff too but nothing heavy
[11:08] <Hibby> I mean, rtty is from the 60s, it's not computationally expensive :p
[11:08] <gm8oti> they just keep bulking out the distros ...
[11:08] <jonsowman> Upu: that'll be fine
[11:09] <fsphil> nice signal again, lots of decodes
[11:10] <jonsowman> 580km/h :o
[11:10] <fsphil> spoke too soon :)
[11:10] <jgrahamc> I know, it's so slow. It was going over 6,000kph a while ago.
[11:10] <fsphil> two bad checksums
[11:11] <fsphil> hey it's doing well considering it was launched in 1999 :p
[11:12] <jgrahamc> Oh. I figured it was still 1999 in Scotland or something :-)

[11:13] <NigelMoby> Afternoon
[11:13] <fsphil> frequency is increasing
[11:13] <UpuMobile> hey
[11:14] <fsphil> howdy NigelMoby
[11:14] <NigelMoby> How's the flight doing?
[11:14] <fsphil> quite bad fading here again, more turbulence maybe
[11:15] <NigelMoby> Eek
[11:15] <UpuMobile> well it seems
[11:15] <Hibby> fsphil: loads of turbulence, worrying about a north sea landing too
[11:15] <UpuMobile> whats the prediction ?
[11:15] <Hibby> crap
[11:15] <UpuMobile> linky ?
[11:15] <Hibby> CUSF said it should have burst quite a few miles back
[11:16] <fsphil> you're save enough from the north sea I think
[11:16] <Hibby> http://habhub.org/predict/#!/uuid=25f77b0352acb71eed1ee2d400a0cb389b808690
[11:16] <fsphil> safe*
[11:16] <Hibby> fsphil: think so
[11:16] <GM4JTJ> still solid S9 signals with fast fading in montrose
[11:16] <Hibby> equally, it's not my project, and they've got reproducable pcbs
[11:16] <UpuMobile> whats the burst altitude suppose to be ?
[11:17] <Hibby> 27km, there's a cutdown too
[11:17] <UpuMobile> ah
[11:17] <UpuMobile> this should be interesting :)
[11:17] <fsphil> gm8oti, you're on the map and have uploaded some decodes
[11:18] <Hibby> indeedio
[11:18] <SpeedEvil> Wow - decent rate closing on .1C
[11:18] <gm8oti> magic! - so nothing to fix ;-)
[11:18] <jgrahamc> That prediction relies on some pretty fast ascent and descent rates. Any idea what the measured ascent rate is?
[11:18] <fsphil> lol
[11:18] <Hibby> supposed to be 8m/s
[11:18] <Hibby> looks to be ~7m/s
[11:19] <fsphil> at a guess it wouldn't be far of that
[11:20] <fsphil> difficult to tell without a proper timestamp
[11:21] <fsphil> 25km exactly, nice
[11:21] <LazyLeopard> Payload's rotating, which makes signal fade. I've half-caught a few lines, but none without errors.
[11:21] <Hibby> got that qrm back
[11:22] <Hibby> as I said earler, it's just a hanging j-pole
[11:22] <fsphil> bad fading again
[11:22] <gm8oti> solid green here - at present
[11:22] <LazyLeopard> There's the usual "would help to have a couple of characters before the $$" issue.
[11:23] <fsphil> yea :)
[11:23] <fsphil> gonna stick that in the wiki

[11:29] <fsphil> wow it's gone nuts
[11:29] <Laurenceb_> hope theres no 'cargo' onboard
[11:29] <Hibby> the number 3 from the checksum is a 0 that changes to a 1, it's changed but no sign of a cutdown yet

[11:31] <fsphil> I can't decode it
[11:31] <Hibby> neither can I... hanging free jpole may be a bad idea for this part of the flight
[11:32] <fsphil> 23.6km
[11:32] <Hibby> we have a green!

[12:49] <Upu> not that the fixed IP is particualarly relevant
[12:50] <jgrahamc> I didn't, I ended up using a Lassen IQ cable.
[12:50] <NigeyS> ahh okies, was going to say, theyre horribly tiny and fiddly!
[12:50] <jgrahamc> Like this: http://www.dpieshop.com/trimble-iqsq-data-cable-to-flying-lead-way-125mm-pitch-p-238.html?osCsid=051a10ffb6c8fc7d7ee6b24d238ce7e3
[12:51] <jgrahamc> The Lassen IQ itself is hot glued to the strip board.

[12:52] <NigeyS> good solution, i may concider that if i use the lassen for ATS-2 for ATS-1 james sent the breakout with a connector pre-soldered
[12:52] <jgrahamc> All I really have left to do is: verify that the IEEE 754 stuff I put in is working and glue in place the battery packs.
[12:52] <jgrahamc> Then I just need to cross my fingers the eroomde and jonsowman got the helium delivered :-)
[12:52] <NigeyS> looks like you got the issues pretty much solved mind, good work :D
[12:53] <jgrahamc> The Telit module was a PITA to work with.
[12:53] <NigeyS> i dont think ive seen anyone use the tsip mode for the gps before .. in flight anyway
[12:53] <jgrahamc> I found the Lassen pretty easy. Seems to get a lock in my back garden without much of a problem, but I'm guessing that the combination of the antenna and the big ground plane are helping that.
[12:54] <jgrahamc> I'm pretty sure that TSIP mode has been used before.
[12:54] <NigeyS> ive found the lassen with the patch antenna very very flakey even outside, i'll be changing the antenna before flight for sure.
[12:55] <jgrahamc> I'm using something like this: http://www.dpieshop.com/trimble-miniature-30v-gps-antenna-sma-connector-5623752-replacement-p-290.html
[12:56] <jgrahamc> And I've also got that mylar ground plane underneath which may be helping.
[12:56] <NigeyS> ah yes i remember, and you trimmed the antenna cables ?
[12:56] MrCraig (~MrCraig@host86-132-11-62.range86-132.btcentralplus.com) joined #highaltitude.
[12:56] <jgrahamc> Yes, I cut the antenna cables because they were crazy long (intended for use in a car) and attached new SMA connectors. That last part was a pain to do.
[12:56] <NigeyS> hey MrCraig
[12:57] <NigeyS> hehe sma crimping .. fun !
[12:57] <jgrahamc> This shows the antenna mounting and the mylar: http://blog.jgc.org/2010/11/gaga-1-capsule-insulation-and-antenna.html
[12:58] <NigeyS> yup, i used the same mylar that you did for lining, that was .. fiddly shall we say
[12:58] <jgrahamc> The crimping was easy, soldering the bloody pin in place wasn't
[12:58] <NigeyS> lol ouch
[12:58] <jgrahamc> Yes, it was a bit fiddly to do the lining.
[12:59] <NigeyS> great stuff but ever so fragile
[13:00] <NigeyS> http://www.youtube.com/watch?feature=player_profilepage&v=TgXjj7h-3qo
[13:00] <NigeyS> thats probably the first time its got a lock in under an hour .. ever
[13:01] <jgrahamc> Wow. I haven't seen a lock from cold taking more than about 7 minutes.
[13:01] <MrCraig> http://habhub.org/predict/#!/uuid=e7dc223946cdb74cdc9e30cef2c88f74391eab60
[13:01] <NigeyS> it gets very annoying, and no chance of a lock inside, makes working with it a bit of a pain
[13:01] <jgrahamc> That foil you are looking looks different to mine. Mine is from a survival blanket and isn't fragile at all. I have tons left over and could mail it to you if you want.
[13:02] <jgrahamc> MrCraig: is that for your launch?
[13:02] <MrCraig> jgrahamc: yes
[13:02] <NigeyS> oh i used normal foil for the outdoor test, the payload box is lined with foil blanket material, seemed to rip quite easy mind
[13:03] <jgrahamc> That's ARTEMIS-1?

[13:05] <NigeyS> hmm, you mean you dont fancy taking a swim? :p
[13:05] <jgrahamc> Each time I look at the GAGA-1 flight prediction it's different. Currently it's doing this crazy path:http://habhub.org/predict/#!/uuid=db253f2e61131bde7417978bc8fcd90eae30e806
[13:05] <MrCraig> You know if it were off the west coast I might consider it but the east just isn't fun... <j/k>
[13:05] <NigeyS> lol
[13:06] <fsphil> launch from here :D
[13:06] <NigeyS> jgrahamc, loop the loop :|
[13:06] <NigeyS> phil has his own helicopter on standby for his launches ;)
[13:07] <jgrahamc> Yeah, crazy.
[13:07] <fsphil> helicopter that can land on water n' everything :)
[13:07] <NigeyS> lol
[13:08] <fsphil> there's actually a couple of good predictions for this week, hopefully it stays that way
[13:08] <NigeyS> fingers crossed
[13:08] <fsphil> or I'll have to hire Upu to chase it ;)
[13:09] <NigeyS> thats a very weird prediction for gaga-1 mind , going to be dependant on where it bursts as to wether or not it does that weird loop thingy
[13:09] <fsphil> would be fantastic to land right where it was launched
[13:10] <fsphil> I don't think it's ever happened before
[13:10] <NigeyS> now thaat would be something, talk about a boomerang!
[13:10] <fsphil> one of the nice things about the hourly predictor is finding things like that
[13:11] <NigeyS> right bbs better get this cat to the vets, another £110 down the drain to be told he's eaten a dodgy bird or something *sigh*

[14:04] <x-f> wow, "Geomagnetic K-index of 6 expected"
[14:04] <NigeyS> could be some resistance from the breadboard though ?

[14:08] <NigeyS> thought so, everythings running ok, just something i noticed last night

[14:18] <Hibby> im a soapdodging type in student friendly with some radio types up here.
[14:18] <SamSilver> the student had not tightend down the nuts
[14:18] <SamSilver> so was called a soapdodger

[14:18] <Hibby> hah! yes indeed, this is what happens when we get students to install things
[14:18] <Hibby> didn't torque the nuts properly, and sent me an email to inform me of this "due to the high winds"
[14:19] <Hibby> I was like.. cheers dude, but we wouldn't have failed you if you'd told us a year ago when you handed in your thesis
[14:19] <MrCraig> skypod landed?
[14:19] <Hibby> MrCraig: and recovered
[14:19] <Hibby> was a quick flight
[14:19] <MrCraig> excellent, good job
[14:20] <SamSilver> well done team
[14:20] <Hibby> station here tracked it excellently. will pass on the message. Lets them get writing that all important report towards the degree
[14:20] <fsphil> nice signal to track this time -- definitely an improvement on the last one
[14:20] <MrCraig> eeek - looks like it was close to landing on the A68
[14:20] <Hibby> fsphil: much more organised group.
[14:21] <Hibby> they had a heater to ensure that internal temp was roughly static amongst other things
[14:21] <fsphil> the wibbly wobbly signal after descent was weird
[14:21] <fsphil> not the normal rapid fading
[14:22] <Hibby> was a jpole hanging loosely from the bottom, I'm guessing it didn't handle the fall well
[14:23] <Hibby> one of the launches next week has a 1/4 wave made from coathanger wire.
[14:23] <Hibby> should be much more stable
[14:23] <Dan-K2VOL> Jpoles seem to be react very bad at being bent up
[14:23] Dan-K2VOL (~Dan-K2VOL@74-143-44-42.static.insightbb.com) left irc: Quit: Leaving.
[14:24] <fsphil> I wonder if the antenna would cause the frequency to shift slightly
[14:24] <fsphil> suppose it depends on how the ntx2 handles a bit of swr
[14:25] <LazyLeopard> Yeah, it got noticably fuzzy during descent. There was also some wobbling during ascent, at least from what I saw (which wasn't that much, given I'm 460km or so from the landing point, and 500km from launch).
[14:25] <Hibby> that's an interesting question, actually.
[14:25] <fsphil> I noticed a similar slow oscillation on the last flight too
[14:25] <LazyLeopard> There were also occasional small jumps in frequency.
[14:26] <Hibby> I didn't get the jump in frequency, but I did get wobbling
[14:27] <LazyLeopard> Yeah, between one and two cycles of oscillation in the time it took to send one string. Unfortunately the wobble also imposed some fading.
[14:27] <Hibby> Indeed. design considerations for the three groups
[14:28] <Hibby> although none of them have any idea about rf stuff
[14:29] <Hibby> just found out we had SNU live on a screen in a conference downstairs, as well as in many of the student computer labs
[14:29] <Hibby> maybe we'll get a "surge" of interest in radio nerdery :)
[14:30] <LazyLeopard> In the short time I was receiving the signal I noted it jump maybe three times, maybe four. Something between a quarter and a third of the shift each time.
[14:30] <Elwell> Hibby: 's OK, you'll always be known as a soapdodger to us, regardless of $proper-job prospects in future :-)
[14:31] <Hibby> Elwell: crap. Thank's for that one, kyle.
[14:31] <Elwell> Hibby: pfft, don't blame it on folder-boy
[14:32] <Hibby> haha, is it my own fault for being the eternal student, then? hmmm?

[14:34] <LazyLeopard> Could have been that, then. Where's it switched on and off?
[14:34] <fsphil> it will try to centre the signal if it drifts near the edge of the waterfall

[14:34] <fsphil> in there somewhere
[14:34] <Hibby> SamSilver: what prompted the soapdodger comment? meant to ask
[14:34] <fsphil> you'll see a tick box, and two sliders for a minimum and maximum waterfall frequency
[14:35] <LazyLeopard> Given it was rather a wide shift, it'd have drifted close to the edge of the waterfall sooner...
[14:35] <fsphil> it uses the centre frequency to work it out
[14:35] <Hibby> // who were you talking to?
[14:35] <LazyLeopard> Hmmm...
[14:35] <fsphil> it's not enabled by default

[14:50] <Laurenceb_> you could have a feed on your website
[14:50] <Laurenceb_> or use RSS

[15:53] <Hibby> SamSilver: I suspect they're in the other lab
[15:53] <Hibby> kettle's done!
[15:53] <SamSilver> i lost side cutters only found them at bed time > top pocket
[15:54] <Hibby> plus im not really the shirt wearing kind
[15:55] <SamSilver> for heavens sake dont hook your snipe in your jocks then
[15:55] <SamSilver> snipes
[15:55] <SamSilver> snips
[15:56] <Hibby> dancing again :/
[15:57] Action: Hibby chooses wire from his myriad colours
[15:58] <Laurenceb_> jock straps?
[15:58] <Upu> they got Skypod back ?
[15:58] <Hibby> also, call me radical, but im soldering a non-ntx2 radio module up the now
[15:58] <Hibby> Upu: yep
[15:58] <Upu> yay :)
[15:58] <Hibby> en route here for debreif, i think
[15:59] <Upu> Super :)
[15:59] <Upu> Wish I'd be able to get on earlier
[16:01] <Hibby> 'salright
[16:01] <Hibby> the big launch is next week
[16:01] <jgrahamc> They've picked up Skypod?
[16:01] <Hibby> 3 payloads, two balloons, one frequency.
[16:01] <Hibby> jgrahamc: yep
[16:01] <jgrahamc> Very nice. Intact?
[16:01] <Hibby> afaik
[16:01] <Hibby> was still transmitting
[16:01] <jgrahamc> Very cool.
[16:01] <Hibby> they used the newly gained foxhunting skills I taught them ;)
[16:02] <Hibby> it's really nicely designed, electronically
[16:03] <Hibby> accelerometer, myriad sensors /etc /etc
[16:03] <Hibby> if the board printing service here was more capable, it would be tiny too.
[16:04] <Hibby> may just have caused myself a major piercing related injury...
[16:05] <Hibby> back, all good.
[16:08] <fsphil> re
[16:08] <jgrahamc> Not sure I like the latest prediction for GAGA-1 launch which puts it descending over Cambridge: http://habhub.org/predict/#!/uuid=35a4d7a0369fe7529fac5f98909e4c21fcc237fc
[16:08] Action: fsphil is hacking floppy drives
[16:10] <fsphil> managed to make one produce smoke :)
[16:12] <Hibby> this little radio module is very nice
[16:12] <Hibby> 4 channels available
[16:12] <Hibby> no enable pin...
[16:13] <SamSilver> what band Hiddy?
[16:13] <SamSilver> freq?
[16:14] <Hibby> 70cm
[16:15] <Hibby> 434.075, 433.9200, 434.600, 434.700
[16:16] <fsphil> nifty

[16:16] <SamSilver> thanx
[16:16] <SamSilver> for linky
[16:17] <Hibby> it's absolutely blasting out with no antenna... signal is much higher than ntx-2
[16:17] <Hibby> colour me hopeful
[16:17] <Hibby> what was the circuit for the voltage divider based rtty system? Anyone know?
[16:17] Action: Hibby is curious as to how it works.
[16:21] <Dan-K2VOL> Hibby, might not want to run transmitters without antennas
[16:21] <Dan-K2VOL> can damage some
[16:21] <Hibby> i know.
[16:21] <Hibby> im lazy :)
[16:21] <Dan-K2VOL> ok lol
[16:21] <Hibby> :p
[16:21] <Hibby> it's got a long track on it, should be fine ish
[16:22] <Dan-K2VOL> looks like a neat pair
[16:25] <eroomde> hmm, just as a word of caution from the bad old days (2006) but we found circuit design units to be very unreliable in flight
[16:25] <eroomde> much more environmentally sensitive that radiometrices
[16:26] <Hibby> eroomde: cheers. shall find out in due course. Again, not my project, I'm just the soldermonkey trackingchap

[16:55] <Hibby> awesome
[16:55] <Hibby> worked nicely.
[16:55] <Hibby> latest news is that the video is corrupted
[16:55] <jcoxon> great
[16:55] <jcoxon> even with the silly telemetry string
[16:55] <Hibby> looks like the camera couldn't handle the temperatures
[16:55] <Hibby> jcoxon: well... that bit wasn't good..
[16:55] <Hibby> spacenearus really struggled with it...
[16:56] <Hibby> as it was ascending, snu recorded it as descending at ~ 0.1C
[16:56] <jcoxon> the telem string was not ukhas standard at all
[16:56] <jcoxon> so we tried to put some hacks in place to allow it
[16:56] <Hibby> jcoxon: indeed. It was an uphill battle to get them to checksum it too
[16:57] <jcoxon> perhaps in future they can use a slightly better format?
[16:57] <jcoxon> Hibby, in what way - occasional dodgey char?
[16:58] <Hibby> jcoxon: hopefully so. The errors on the website should make it patently clear that being lazy and not doing sums on the flight computer isn't a good idea
[16:58] <Hibby> jcoxon: more like "but why? The software's complete"... "It's a wise idea to check that the downlinked data is, infact accurate" etc
[17:00] <jcoxon> yeah
[17:00] <jcoxon> we chose teh ukhas standard for a reason really
[17:00] <LazyLeopard> Hibby: I've got a slightly-sanitised log of what I received down here, if you want any ammo for the "You know, data sometimes gets a little garbled in transmission!" argument... ;)
[17:00] <jcoxon> i think the way we suggest it is sensible
[17:01] <Hibby> indeed. For the couple of hours it would have taken to implent the floattostring library I emailed them...
[17:01] <jcoxon> Hibby, or we do allow nmea style lat/lon
[17:01] <jcoxon> so no need to change anything
[17:01] <Hibby> jcoxon: that bit was fine, but it's the rest of it that was the issue, lol.
[17:01] <jcoxon> oh right
[17:02] <jcoxon> oh well
[17:02] <jcoxon> lessons learnt
[17:02] <Hibby> was going at 6400km/h quite a lot, lol

[17:03] <Hibby> aye?
[17:03] <jcoxon> as per the suggested protocol

[18:06] <stilldavid> this time around they were $90 each
[18:06] <stilldavid> and $110 for the 1500 gram
[18:07] <Dan-K2VOL> I think they don't want to deal with individuals
[18:07] <jcoxon> eek
[18:07] <jcoxon> in the UK most people get them through rocketboy

[18:08] <jcoxon> well kaymont is US based

[18:29] <NigeyS> may even be bigger than 16ft

[18:29] <SpeedEvil> I cheated.
[18:29] <fsphil> from ground to roof this house is about 8 metres
[18:29] <SpeedEvil> I have a (now dissasembled) mast, made of bamboo.

[18:30] <SpeedEvil> 9->5->3->1
[18:30] <SpeedEvil> Painted, and tied together securely. Worked well for a total height of 6-7m or so.
[18:31] <NigeyS> hmm, i dont have any bamboo, but i do have alot of 45mm pvc tubing
[18:33] <SpeedEvil> It's fairly mechanically weak. The lovely thing about bamboo is that it's damn near impossible to break. PVC isn't very structurally strong.
[18:34] <NigeyS> thats true, i think id be ok the washing line pole but not permenantly, id be worried about the wind catching it, the whole pole is rusted to hell

[19:26] <NigeyS> james, is it possible to use more than 1 instance off nss ?
[19:26] <NigeyS> of*
[19:26] <Hibby> is there testing on 868 these days? how exciting
[19:27] <fsphil> yea I'm not parting with it :)
[19:27] <jcoxon> fsphil, i think the key problem with funcube dongle is that amateur radio people are involved (no offence)
[19:27] <fsphil> lol
[19:27] <fsphil> I agree
[19:27] <jcoxon> NigeyS, in theory but it ain't pretty
[19:27] <Hibby> jcoxon: lol.
[19:27] <NigeyS> thought not, oki np
[19:27] <fsphil> they're an odd bunch
[19:27] <jcoxon> bless 'em but yes
[19:28] <Hibby> jcoxon: we are indeed, aye.
[19:28] <fsphil> the catch with 868mhz is still going to be the limited transmit time allowed
[19:28] <Hibby> given the state of most amateur radio software && websites...
[19:28] <jcoxon> what duty is it?
[19:28] <jcoxon> Hibby, oh gosh yes
[19:28] <Hibby> fsphil: do continue?
[19:28] <Hibby> generally we're not the most reliable lot.
[19:28] <jcoxon> my favourite example is Multipsk - what on earth is going on there
[19:29] <fsphil> 10% for the 500mw band
[19:29] <jcoxon> http://i1-win.softpedia-static.com/screenshots/MULTIPSK_1.png
[19:29] <Hibby> hahahah, that program is aweful
[19:29] <fsphil> My Eyes!!!
[19:29] <Upu> jesus my eyes
[19:29] <Upu> lol
[19:29] <jcoxon> but awesome for decoding
[19:29] Action: fsphil puts on his 3D glasses
[19:29] <fsphil> That's Worse!!!!
[19:29] <jcoxon> at least fldigi in nice (with some dl/ukhas adjustments
[19:29] <jcoxon> )
[19:30] <jcoxon> is*
[19:30] <Upu> was fun today
[19:30] <jcoxon> hehe
[19:30] <Upu> I'll get more practice on Saturday, I'm at the radio club doing my fountation and intermediate but I'll try tune their rigs in
[19:31] <fsphil> the only part of the 87x band that allows 100% is limited to 5mw output
[19:31] <fsphil> it was nice being close to a launch that wasn't my own :)
[19:31] <jcoxon> fsphil, we could blast through a pick
[19:31] <jcoxon> pic*
[19:33] <jcoxon> right, Hell beacon complete
[19:33] <jcoxon> 62.3g
[19:33] <fsphil> what is it going to be transmitting?
[19:34] <jcoxon> just ID strings and info about the beacon
[19:34] <jcoxon> no dynamic data
[19:35] <jcoxon> now i need to get it to jgrahamc

[19:36] <chembrow> jcoxon what micro have you used for it?
[19:36] <MNSP> hello all :)
[19:36] <jcoxon> just a spare atmega168 with the arduino bootloader
[19:37] <jcoxon> its mimimal components
[19:37] <NigeyS> jcoxon, im thinking of sending the rtty through my beacon if i can figure out how
[19:37] <Hibby> jcoxon: my personal favourite option.
[19:37] <jcoxon> NigeyS, not sure how to do it through those sparkfun tx'ers
[19:37] <chembrow> cool. I'm playing with a TI msp430 to possibly use as the basis of a beacon - http://karuppuswamy.com/wordpress/2010/10/09/debugging-ez430-f2013-mcu-with-mspdebug-tool-in-ubuntu-linux/
[19:38] <chembrow> had it for a while but not thought of a use till now
[19:38] <jcoxon> chembrow, well Hellschreiber is easy as its OOK
[19:38] <jcoxon> just the timings are a bit hard + making a 'font library'
[19:38] <NigeyS> aye, it's going to be a challenge
[19:38] <chembrow> OOK? the librarian from Discworld?
[19:38] <jcoxon> but i've written one so you can steal it
[19:38] <jcoxon> on/off keying
[19:38] <chembrow> ah.
[19:39] <jcoxon> :-D
[19:39] <chembrow> what's the difference between hell and cw?
[19:39] <jcoxon> awesomness
[19:39] <Hibby> :D
[19:39] <jcoxon> well you generate it the same
[19:39] <fsphil> lol
[19:39] <jcoxon> just turning the tx'er on and off
[19:40] <fsphil> I'm going to use fsk for hell -- so it'll be repeated twice, the second one being a negative of the first
[19:40] <jcoxon> however hell is a bit like a bitmap
[19:40] <jcoxon> you 'draw' the character
[19:40] <jcoxon> in a 7x5 grid
[19:40] <jcoxon> and it requires your brain to decode it
[19:40] <jcoxon> which is very efficient
[19:40] <chembrow> :)
[19:41] <chembrow> and you use fldigi to get the image?
[19:41] <jcoxon> yeah
[19:41] <jcoxon> shall i record some for you
[19:41] <chembrow> yes please
[19:47] <jcoxon> oh dear that was a terrible recording

[20:15] <MNSP> But I think it was great! Missed the touchdown as the end though
[20:15] <Lunar_Lander> oh ok
[20:15] <MNSP> do we know if the payload was recovered safe

[20:18] <Lunar_Lander> yeah
[20:18] <Lunar_Lander> I wonder how long it will hold
[20:19] <MNSP> has anyone done a two stage recovery? That animation reminded me
[20:19] <Lunar_Lander> Viking worked until the 1990's when they did a mistake and the antenna was pointed away from earth
[20:19] <MNSP> Or a timed parachute deployment?

[20:22] <Lunar_Lander> I think that wasn't tried yet MNSP
[20:22] <MNSP> Hmm, I've been thinking about the two stage recovery system
[20:23] <MNSP> A drogue chute followed by main that gets deployed at a certain height
[20:23] <MNSP> but thats about as far as I've gotten so far
[20:24] <Lunar_Lander> like on Mercury, Gemini and Apollo
[20:24] <Lunar_Lander> or Joe Kittinger's chute
[20:26] <MNSP> but how to do with some aa batteries, a polystyrene box, an arduino and lots of good will but little knowledge, my stumbling block :)

[20:28] <Lunar_Lander> yeah
[20:28] <Lunar_Lander> I think the single chute is the safest one
[20:28] <MNSP> yeah thats where Im at too Lunar
[20:28] <chembrow> what advantage do you think a 2-stage might have?

[20:30] Laurenceb__ (~laurence@host86-141-74-3.range86-141.btcentralplus.com) joined #highaltitude.
[20:30] <MNSP_> so my thinking was it would be safer for a large chute to be deployed lower down
[20:32] <chembrow> I suppose. does anyone know of chute failures happening?
[20:33] <MNSP_> also it would be a more immediate descent
[20:33] <Lunar_Lander> I think HoHoHo-I had a bad chute mounting
[20:33] <Lunar_Lander> you see the rapid rotation and so on in the video
[20:35] <MNSP_> I 'researched' two stage stuff and found that a lot of the model rocketry guys had tried it out
[20:36] <MNSP_> but I didn't find anything that convinced me of their desing for transfer to HAB
[20:38] <Lunar_Lander> yea
[20:40] <MNSP_> so I guess we can put that down to a work in progress

[20:48] <fsphil> you can't really waterproof it, and still include a camera. having a camera housing will quite often mist up and give bad images

[20:49] <Shuffty> or washing up liquid - I believe that has the same effect..

[21:16] <MNSP_> *cover
[21:17] <MNSP_> does that mean the ntx2 was receivable (?) all over the country?
[21:17] <Hibby> more or less, aye

[21:17] <MNSP_> gosh!!! thats not bad for a little 10mW transmitter
[21:18] <MNSP_> lol
[21:18] <Hibby> I had it coming in at S9 when it was 27k up and 70+ miles away.
[21:18] <Hibby> admittedly, my systems a bit of an exception to the rule

[21:26] <Shuffty> ordered the other bits for my lassen - if id thought about it before hand, i'd have been sorted by now. Hope to have something breadboarded and running over the weekend...
[21:27] <Shuffty> I couldnt hear it in manchester... but that might have been my shite aerial!
[21:27] <Shuffty> :-)
[21:28] <fsphil> nice signal here
[21:28] <Hibby> http://twitpic.com/4hpq7o
[21:28] <fsphil> oooooh
[21:28] <fsphil> I can see my house!
[21:31] <MNSP_> lol
[21:31] <Hibby> not bad, eh?
[21:31] <fsphil> watching the video, is that the j-pole antenna I see bouncing around?
[21:32] <Hibby> fsphil: different launch
[21:32] <Hibby> that was a simple wire dipole that hung down
[21:32] <fsphil> aaah that was the first one
[21:33] <fsphil> I can see what looks like a hook on the top left
[21:33] <Hibby> today's video corrupted sadly
[21:33] <fsphil> ack
[21:34] <MNSP_> :(
[21:34] <fsphil> nice dummy payload drop
[21:34] <MNSP_> do you know why Hibby?
[21:34] <fsphil> was that recovered?
[21:34] <Hibby> MNSP_: don't think the camera liked -40ish
[21:35] <Hibby> fsphil: aye.

[21:56] <Hibby> jcoxon: I've caught the bug... plan on implementing it with my own launch/payloads in summer... curious to include ssdv :)
[21:56] <jcoxon> haha, hab is addictive
[21:56] <fsphil> ooh
[21:56] <Hibby> totally.
[21:56] <jcoxon> Hibby, ssdv is fsphil's invention
[21:57] <Hibby> indeed, I figured that. I like the idea, makes an awful lot of sense.
[21:57] <fsphil> still got a few ideas for improving it
[21:58] <jcoxon> Hibby, i've got my SSTV payload sitting on a shelf
[21:58] <jcoxon> just needs fresh batteries
[21:58] <jcoxon> so will fly that in teh summer
[21:58] <fsphil> jcoxon, think this would work close enough to the ntx2? http://www.radiometrix.com/content/tx3h
[21:59] <jcoxon> fsphil, yeah - hte data sheet is nearly identical
[21:59] <jcoxon> no onboard reg
[21:59] <jcoxon> requires 5v
[21:59] <fsphil> makes sense, considering the current it uses
[21:59] <fsphil> gonna eat through the batteries
[21:59] <jcoxon> 10% duty
[21:59] <jcoxon> but yeah
[22:00] <fsphil> even at 10% it's still a good chunk more
[22:00] <jcoxon> not for long duration
[22:00] <jcoxon> thats for sure
[22:00] <Hibby> fsphil: how do you implement ssdv?
[22:01] <fsphil> I wrote a small library Hibby, you pass a jpeg file to it and it produces the 256-byte packets
[22:01] <Hibby> Cool. What's the hardware in use?
[22:01] <fsphil> the jpeg has a few restrictions
[22:01] <fsphil> it's been used on an atmega644p -- but it can likely be used on less
[22:02] <Hibby> nice.
[22:02] <fsphil> doesn't use that much memory, but some of the smaller chips would struggle
[22:02] <Hibby> was considering bifferboard as my flight computer, if not only because usb support would be nice in the camera => ground things
[22:02] <fsphil> usb would be a massive ++ .. you could use much better cameras
[22:03] Tvilling (~Tvilling@c4383BF51.static.bluecom.no) left irc: Quit: Changing server
[22:03] <jcoxon> interesting i downgraded my camera for my sstv payload
[22:03] <Hibby> aye. Debian running on a bifferboard. But battery packs might kill it.,
[22:03] <jcoxon> interfacing with big cameras is a massive challenge
[22:03] <jcoxon> switching between usb mode and picture mode

[22:04] <jcoxon> very few have remote control
[22:04] <fsphil> I suppose if the image is only 320x240 it's not that important
[22:04] <Hibby> aye, tht's what's held us back with this set of launches
[22:04] MNSP (Mit@cpc1-lutn3-0-0-cust700.9-3.cable.virginmedia.com) joined #highaltitude.
[22:04] <jcoxon> you can use a Canon A60
[22:04] <fsphil> ssdv can do bigger pictures but it would take *ages* to transmit it :)
[22:04] <jcoxon> that has remote mode
[22:04] <jcoxon> instead i've gone with a jpeg camera
[22:04] <jcoxon> so much easier to use, none of this USB host rubbish
[22:05] <fsphil> yea -- take picture, read jpeg
[22:05] <Hibby> what's the rharrison link for raw data from snu?
[22:05] <jcoxon> http://www.robertharrison.org/listen/view.php
[22:05] <Hibby> danke
[22:05] <Hibby> forgot the /listen/
[22:05] <jcoxon> but if you look on the wiki you can filter that
[22:05] <jcoxon> http://wiki.ukhas.org.uk/projects:dl-server
[22:06] <fsphil> did I imagine it or is there a link for manually adding telemetry strings?
[22:06] <jcoxon> right we need to fix the chase car issue
[22:06] <jcoxon> yes
