[07:29] <natrium42> ava is alive in the sea?
[07:29] <Upu> well no Ava is dead as a door nail probabably
[07:30] <Upu> but the second payload had a commercial GSM tracker in it which is still alive and reporting location
[07:30] <natrium42> aah
[07:30] <natrium42> and it's in the sea?
[07:30] <Upu> and Ava is attached to it with a carabiner :)
[07:31] <Upu> yep
[07:31] <Upu> http://g.co/maps/hn9q8
[07:31] <Upu> A last night
[07:31] <Upu> B this morning
[07:31] <Darkside> oh wow
[07:31] <Darkside> how long will the batteries last?
[07:31] <Upu> they are getting low
[07:31] <Darkside> eek
[07:31] <Upu> suspect as its so far out its running at full power to transmit on GSM
[07:32] <Darkside> yeah i bet
[07:32] <number10> doesnt seem to be moving inland
[07:32] <Upu> however it is following a fairly linear path
[07:32] <Upu> yeah interesting that
[07:33] <Upu> anyway Steve's calling the coast guard this morning to ask them for advise
[07:33] <daveake> :)
[07:33] <Upu> we are just gobsmacked it managed to get that far out
[07:34] <natrium42> wow
[07:34] <natrium42> must have gone high?
[07:34] <daveake> A few miles NE and it'll reach cloud2's landing spot
[07:35] <number10> Upu that seems to be roughly the direction of the wind
[07:36] <daveake> Upu I got 2 locations from mine via GSM at approx 8-9 miles from the coast, whilst still in the air. Nothing at all after impact.
[07:37] <daveake> Either too far for a signal, or the box broke up (it was doing 30mph sideways) and the tracker sunk
[07:39] <Upu> thats the thing natrium42
[07:39] <Upu> it was 1.6kg under a 1600g Hwyoee with we think about 5m/s
[07:39] <Upu> but looking at where Mondo went
[07:39] <Upu> it must have got to ~40k
[07:39] <Darkside> thats weird
[07:39] <Darkside> oh wow
[07:40] <Upu> sadly no alitude data
[07:40] <Upu> and the decent was slow
[07:40] <Darkside> no proof :-)
[07:40] <daveake> :(
[07:40] <Darkside> oh sorry, that was meant to be a :-(
[07:40] <Upu> lol
[07:40] <Darkside> >_>
[07:40] <daveake> lol
[07:40] <natrium42> pix or it didn't happen?
[07:40] <Darkside> YOU WILL NOT BEAT MY RECORD
[07:40] <Darkside> grrr
[07:40] <Upu> well I might have pix
[07:40] <Upu> see what Steve comes back with
[07:41] <Upu> might try compare temperature data from Ava with Mondo when I get time later on
[07:41] Action: natrium42 sends the canadian navy http://www.counterweights.ca/blog/wp-content/uploads/2010/12/aabcnavy01.jpg
[07:41] <Darkside> a pressure sensor would be a good idea
[07:41] <Upu> :)
[07:41] <Darkside> use pressure altitude
[07:41] <Upu> I don't have one
[07:42] <Upu> was going to rebuild the whole thing anyway after this flight
[07:43] <Upu> A560 was playing up before launch yesterday
[07:46] <Upu> it wa sso pink :/ https://picasaweb.google.com/118244444241111963790/201110AvaLaunch#5658661527910597746
[07:46] <number10> unfortunately the wind over the next 24 hours is expected to be off shore
[07:46] <Upu> we don't have 24 hours anyway the GSM battery will die before then
[07:46] <natrium42> whoa, that's pink
[07:47] <daveake> "If the payload's pink, it'll end up in the drink". It's an olde HABers' saying.
[07:47] <Upu> lol
[07:47] <Darkside> well, it is now
[07:47] <daveake> Dammit. I used some pink wire in cloud2. That's where I went wrong ...

[08:41] <fsphil> good set of pics Upu

[08:42] <fsphil> any thoughts on why the gps went nuts?
[08:42] <Upu> boat on its way apparently
[08:42] <Upu> antenna
[08:42] <Upu> very odd though
[08:42] <Upu> managed to get 3 sats
[08:43] <fsphil> tis odd, I don't remember that happening before

[08:56] <fsphil> sea rescues are all the rage atm
[08:56] <Darkside> hahaha
[08:56] <Darkside> we try and avoid them
[08:56] <fsphil> the north sea has taken to many. this far, no further! the line must be drawn here!
[08:57] <fsphil> I wonder how it was described to them :)
[08:57] <fsphil> "What's it look like?" "Pink .. very very pink"
[08:58] <Upu> tentative here
[08:58] <Upu> but Ava is currently doing 30 mph back towards land
[08:58] <Upu> now I don't think its doing that under its own steam
[08:58] <fsphil> that's a good sign
[08:58] <fsphil> this would be the best recovery ever
[08:58] <SpeedEvil> :)
[08:58] <fsphil> which payload had the bag of stuff stuck on the side?
[08:59] <SpeedEvil> Possibly the balloon?
[09:00] <Upu> the white one
[09:00] <daveake> wow. 30mph means it's on the boat

[09:00] <Upu> it was a bag of mustard seed
[09:00] <Upu> don't ask
[09:00] <fsphil> lol
[09:00] <daveake> lol
[09:00] <fsphil> I can imagine them taking an interest in that

[09:46] <nosebleedKT> why float?
[09:46] <fsphil> made of polystyrene, that stuff floats good
[09:46] <nosebleedKT> its howeey balloon?
[09:46] Josh_ (02da8665@gateway/web/freenode/ip. left irc: Ping timeout: 252 seconds
[09:46] <fsphil> it was yea, 1600g
[09:47] <fsphil> it may have gotten very close to 40km
[09:47] <fsphil> but the gps failed so we don't know
[09:47] <SpeedEvil> Were there cameras?
[09:47] Action: SpeedEvil wonders how possible it's to tell altitude from pics.
[09:47] <fsphil> ava had, the other one didn't (the one that's reporting position now)
[09:47] <fsphil> now that would be an interesting project
[09:47] <fsphil> measure points on the ground
[09:48] <SpeedEvil> I was thinking more horizon curvature
[09:48] <nosebleedKT> eee I have 1600g at home from howeey
[09:48] <fsphil> it was a clear day so there's plenty of ground
[09:48] <fsphil> me too nosebleedKT :)
[09:48] <nosebleedKT> But i dont want float
[09:48] <fsphil> I'm hoping it gets >40km
[09:48] <nosebleedKT> im afraid of floating
[09:48] <fsphil> that's a risk you have to take with these unfortunately, unless you have a cut-down
[09:49] <nosebleedKT> i dont have a cutdown either
[09:49] <SpeedEvil> Or simply fill it for 5m/s
[09:49] <SpeedEvil> I don't think any fast ascending balloon has floated?
[09:49] BrainDamage (BrainDamag@i.love.tiltshellz.org) left #highaltitude ("Leaving.").
[09:49] <fsphil> no that's true
[09:49] <nosebleedKT> maybe for first launch i will fill it for 33km max
[09:49] <fsphil> upu's may have floated a bit to get that distance, but it didn't float too long if it did
[09:50] BrainDamage (BrainDamag@i.love.tiltshellz.org) joined #highaltitude.
[09:50] <SpeedEvil> As you decrease the fill, you'll go higher, but at some point float
[09:50] <fsphil> I'm not sure a 1600kg has ever burst as low as 33km
[09:50] <fsphil> er
[09:50] <fsphil> 1600g
[09:50] <nosebleedKT> last time you all told me that if i fill it for about 35km it will float.
[09:50] <fsphil> 1600kg balloon ... yea I'd like to see that
[09:51] <fsphil> it might float
[09:51] <fsphil> there's no way to be sure
[09:51] <nosebleedKT> so i will fill it with more helium so it goes around 33km
[09:51] <fsphil> you would have to use a *lot* of helium
[09:51] <fsphil> or, add air
[09:51] <fsphil> that might work
[09:52] <nosebleedKT> your calculator shows 7.30 m3
[09:52] <SpeedEvil> Should do, yes
[09:52] <nosebleedKT> for33km
[09:52] <SpeedEvil> Add air, you decrease burst altitude, and rise rate
[09:52] <nosebleedKT> Ascent Rate: 7.93 m/s
[09:52] <nosebleedKT> already
[09:53] <nosebleedKT> that is much
[09:53] Action: SpeedEvil ponders easy cutdown.
[09:53] <fsphil> that's a lot of HE
[09:53] <nosebleedKT> Time to Burst: 69 min
[09:53] <SpeedEvil> H2+air + sparkplug
[09:53] <fsphil> seriously yea, a cut-down would be easier, cheaper and more reliable
[09:53] <nosebleedKT> you know someone that makes cutdown mechanisms?
[09:53] <fsphil> though xaben's triggered on the ground yesterday
[09:53] <nosebleedKT> I would buy one
[09:54] <fsphil> SpeedEvil, that would work pretty good :)
[09:54] <nosebleedKT> can anyone sell me a reliable cutdown?
[09:54] <fsphil> don't think anyone sells them
[09:54] <nosebleedKT> donates?
[09:54] <fsphil> have you any nichrome wire?
[09:54] jcoxon (~jcoxon@ joined #highaltitude.
[09:54] <jcoxon> natrium42, is on hackaday
[09:55] <SpeedEvil> I like ceramic resistors.
[09:55] <jcoxon> not sure he'd be too happy about that
[09:55] <SpeedEvil> There are ones that are specced to 350C surface temperature@1W
[09:55] <fsphil> he's finally be spotted!
[09:55] <nosebleedKT> I dont have but i can find. But i dont understand the rest circuitry to make the whole mechanism
[09:55] <jcoxon> fsphil, get out
[09:55] Action: fsphil gets his coat
[09:55] <SpeedEvil> Place them butting against a polythene tape, with a wrap of insulation, and you're done.
[09:56] <BrainDamage> you simply need a large mosfet to use as a switch that can handle a large current
[09:56] <Darkside> mmm, SPOT don't like you messing with their trackers do they
[09:56] <SpeedEvil> Or a servo inside the payload, and a little hook
[09:56] <fsphil> feeling better jcoxon?
[09:56] <jcoxon> yeah
[09:56] <jcoxon> i'm alive
[09:56] <fsphil> sweet
[09:56] <Darkside> SpeedEvil: but the grease could freeze
[09:56] <fsphil> everyone he's got the flu atm
[09:56] <jcoxon> Darkside, yeah thats very true
[09:56] <fsphil> I've avoided it so far
[09:56] <jcoxon> i wouldn't want my advancement of the hack on there
[09:56] <SpeedEvil> Darkside: True, however payloads with cameras basically don't hit under -20C ever
[09:56] <SpeedEvil> And you can test that in your freezer
[09:57] <fsphil> spot should encourage it, have some easy way to pass very tiny amounts of data
[09:58] <Darkside> but they don't
[09:58] <jcoxon> the one thing is that those spot models are very old
[09:58] <jcoxon> so they might not care
[09:58] <fsphil> it shouldn't matter to them that the data isn't gps
[09:58] <Darkside> because they can charge more for sending data
[09:58] <nosebleedKT> anyway, my flight goes for after april 2012 for sure, so I can plan the cutdown a bit later
[09:59] <fsphil> nosebleedKT, just a matter of passing current through the wire or a very small resistor. they get very hot and burn the cord
[09:59] <fsphil> the only complicated bit is knowing when to switch it on
[10:00] <fsphil> time limit, or gps fence (I think that's the term?)
[10:00] <nosebleedKT> yes i understand the logic. but i dont think i can do it in practice
[10:00] <Darkside> or activate it from the ground
[10:01] <fsphil> you switch it on or off with a mosfet, which can be controlled by a single pin on the computer
[10:01] <nosebleedKT> sounds easy
[10:03] <nosebleedKT> but from where it will draw the power?
[10:04] <BrainDamage> battery
[10:04] <nosebleedKT> extra battery?
[10:04] <fsphil> it won't need much current -- but I would suggest having it's own battery
[10:04] <fsphil> -'
[10:04] <nosebleedKT> volts?
[10:04] <fsphil> experiment :)
[10:04] <fsphil> depends on how long the wire is
[10:04] <nosebleedKT> lol, im last here to make experiments:(
[10:05] <BrainDamage> P=V^2/R, you'll want 1-5W
[10:05] <BrainDamage> R is ridicolously small, few mOhm
[10:06] <BrainDamage> unless you get a nichrome thin like a hair
[10:07] <nosebleedKT> Very strange
[10:07] <nosebleedKT> on cusf burst calc
[10:08] <nosebleedKT> i have payload weight of 1000g
[10:08] <nosebleedKT> and i get some results
[10:08] <nosebleedKT> I increase the payload weight to 2000g
[10:08] <nosebleedKT> and results are almost the same!
[10:08] <nosebleedKT> with a H1600g
[10:09] <Darkside> oh
[10:09] <nosebleedKT> 1kg weight difference and same results?
[10:09] <Darkside> the hwoyeee 2000g data isnt correct
[10:10] <Darkside> oh
[10:10] <Darkside> 1600g, nvm
[10:10] <nosebleedKT> 1600g
[10:10] <nosebleedKT> Who can fix those data please?
[10:10] <nosebleedKT> I cant flight a balloon like that
[10:10] <fsphil> that might be correct
[10:10] <nosebleedKT> im based on those data too much
[10:11] <fsphil> your neck lift is 5490g -- the difference between 1000g payload and 2000g payload isn't going to be much
[10:12] <fsphil> (this is using a fixed burst point rather than ascent rate)
[10:14] <nosebleedKT> I hope until April 2012 those data get more accurate
[10:14] <nosebleedKT> :)
[10:15] <fsphil> you should launch a smaller balloon before then, get some practice :)
[10:15] <fsphil> test the cut-down
[10:16] <nosebleedKT> yes, im thinking of that for much time now
[10:16] <nosebleedKT> :9
[10:16] <nosebleedKT> :(
[10:16] <nosebleedKT> which is sad cause i dont have the money
[10:16] <nosebleedKT> last time i was very close to get a job
[10:17] <nosebleedKT> in the end we were two guys left from the whole interviews
[10:17] <nosebleedKT> and they took him cause he hot family
[10:17] <nosebleedKT> got*
[10:17] <nosebleedKT> never again i reached so close
[10:18] <nosebleedKT> and the money were so good
[10:18] <nosebleedKT> 800e + 200e insurance
[10:24] <Upu> back now
[10:26] <nosebleedKT> hey Upu
[10:27] <nosebleedKT> got the payload?
[10:27] <nosebleedKT> fsphil: what was the other thing i have to buy for the helium tank? Something for the filling i think.
[10:28] <fsphil> regulator
[10:28] <fsphil> sometimes they're just called balloon fillers
[10:28] <nosebleedKT> ?
[10:28] <nosebleedKT> some ebay link
[10:28] <nosebleedKT> ?
[10:28] <fsphil> it's the bit that goes on the top of the tank, and you use it to get the helium out in an orderly fashion :)
[10:29] <Upu> not yet waiting on Steve
[10:29] <Upu> I think he's heading over there I'm 200 miles away atm :)

[10:29] <nosebleedKT> Upu: did u have camera on 40km>
[10:29] <nosebleedKT> ?
[10:30] <Upu> oh yes
[10:30] <Upu> 5 cameras
[10:30] <nosebleedKT> lool
[10:30] <fsphil> ooh did you get the external camera?
[10:30] <fsphil> the little arm thingy
[10:30] <Upu> 2 micro video lowres chinese jobbies
[10:30] <Upu> one facing up from payload under mine towards the balloon
[10:30] <Upu> one facing out
[10:30] <Upu> 1 A560 sidewards
[10:30] <nosebleedKT> Upu so r we going to see pics from 40km?
[10:30] <Upu> 1 360 Bloggie out the bottom (that should be epic if it survives)
[10:31] <Upu> and another out the side
[10:31] <fsphil> sd cards are pretty hard
[10:31] <Upu> Depends if the SD cards didn't fry in the water
[10:31] <fsphil> though it was in there for a while
[10:31] <nosebleedKT> mhh
[10:31] <Upu> I'm hoping
[10:31] <Upu> the batteries in the A560 were flat when it landed
[10:31] <nosebleedKT> when r u getting it?
[10:31] <Upu> no idea
[10:31] <nosebleedKT> :(
[10:31] <Darkside> you best not be breaking my record there Upu :P
[10:31] <fsphil> lol
[10:32] <Upu> well not sure we can prove altitude from a picture
[10:32] <Darkside> heh
[10:32] <Upu> see if we get anything back and I'll compare with with Google earth
[10:32] <Darkside> hehe
[10:32] <Upu> fingers crossed
[10:32] <Upu> it had to be over 36k
[10:32] <Darkside> yeah
[10:32] <Upu> to get that far out
[10:32] <fsphil> or floated
[10:33] <Upu> yesterday morning I posted 2 predictions
[10:33] <nosebleedKT> why the gps failed?
[10:33] <Upu> one was dumb as it had the time in as 19:99 anyone got the other one
[10:33] <Upu> antenna on GPS seems to have failed
[10:33] <nosebleedKT> which one did u have ?
[10:33] <Upu> as it went up it could see less and less sats till it got 0
[10:33] <Upu> Inventek active patch
[10:33] <nosebleedKT> aaa
[10:34] <Upu> anyone got the second prediction I posted ?
[10:34] <SpeedEvil> Upu: For submerged electronics.
[10:34] <SpeedEvil> Upu: Remove battery. Wash in clean hot water with some detergent in
[10:35] <Upu> ok
[10:35] <SpeedEvil> After dissasembling as much as you can
[10:35] <Upu> look at Mondos path
[10:35] <SpeedEvil> Then dry for a day or so at 80C or so
[10:35] <Upu> it was a float with a slow decent I think
[10:35] <SpeedEvil> Trying powering it on with saltwater on it is a really bad idea, even if it's dried a bit
[10:36] <Upu> yeah don't worry going to try dry them out
[10:36] <Upu> I'll speak to Steve when he has then back

[10:42] <futurity> Morning
[10:43] <Hibby> marnin
[10:43] <futurity> Great fun yesterday tracking the 3 balloon.
[10:44] <futurity> Does anyone know if they were all recovered?
[10:44] <Upu> is there anyway to filter the KML out so I can just get MONDO data ?
[10:44] <Upu> http://spacenear.us/tracker/data.php?format=kml
[10:45] <futurity> Upu: i don't know enough about the output api, but can you download it all and then grep for MONDO?
[10:45] <Upu> yup can but there are multiple lines
[10:45] <futurity> oh i see
[10:45] <futurity> it'll need a script to do it then
[10:46] <futurity> posible to do
[10:46] <futurity> just downloading it to see how easy it would be to do
[10:47] <Upu> Don't spend too much time on it I'm fairly confident we got a float
[10:48] <SpeedEvil> awk -F": " '/MONDO/{$1=""}'|sort -u
[10:48] <SpeedEvil> should I think pull all of the mondos out
[10:48] <SpeedEvil> It will leave duplicate errored lines
[10:50] <futurity> Upu: are you looking for it in KML format, or just the description lines?
[10:51] <Upu> I was wondering if I could get a KML for each payload but don't worry about it I have another plan thx though
[10:52] <futurity> ok, scripting wise, it you do a simple loop and in the loop find the index of the next <Placemark> and then the index of the next </Placemark>
[10:53] <futurity> then if there is a MONDO indexed between the two, print it, otherwise dump it
[10:54] <futurity> Upu: was MONDO your payload?
[10:54] <futurity> or were all 3 payloads part of a team effort?
[10:56] <costyn> hi all
[10:57] <costyn> sorry to have missed the 3 launches yesterday; had a fully planned day unfortunately. been reading the scrollback; exciting stuff :)
[10:57] <Upu> no
[10:57] <Upu> but it was launched at the same time
[10:58] <Upu> does anyone know MONDO's decent rate ?
[10:58] <Upu> at 10k yesterday ?

[11:51] <Upu> the video camera was still running ... probably ran out of capacity after 3 hours but it was still on

[11:55] <Upu> anyway dog walk time
[11:56] <SamSilver> I am thinking it was an alti record and that it did not float
[11:56] <fsphil> it was pretty heavy

[12:48] <Upu> oh ok
[12:49] <fsphil> I was forced to leave and have a nice lunch
[12:49] <Upu> lol
[12:49] <Upu> yeah I appreciate watching a string of 0's wasn't that interesting
[12:49] <fsphil> I just got the last traces of it on the waterfall when I got back
[12:49] <Upu> it floated thats for sure
[12:49] <fsphil> I was still hoping to track it, just bad timing
[12:50] <fsphil> left the auto-tuner with xaben but it didn't seem to catch anything
[12:50] <fsphil> not sure if it drifted or the signal just wasn't strong enough
[12:52] <fsphil> oh sweet, next weeks winds are south-east

[13:01] <Upu> I can arrange collection if you like
[13:01] <Upu> up to you which ever is convenient
[13:01] <Upu> have you managed to remove the SD cards ?
[13:02] <fsphil> Oct 01 15:01:49 <UpuMobile> ava going down? tnx

[13:03] Hiena (~boreger@ left irc: Remote host closed the connection
[13:03] <fsphil> a few minutes after you asked that people started loosing the signal
[13:03] <Upu> yeah
[13:04] <fsphil> Oct 01 15:07:30 <ingersol> losing signal quickly last decent packet was #1159, see you all next saturday...see Metro newspaper for Thursday!
[13:04] <Upu> what altitude do you normally get cambridge launches at fsphil ?
[13:04] <fsphil> 15km Upu
[13:04] <fsphil> but it varies
[13:04] <fsphil> never lower than 15km
[13:04] <fsphil> likely a bit more
[13:05] <fsphil> plus this one was further away than normal
[13:05] <fsphil> so I'd say 16/17km when I lost the signal
[13:06] <fsphil> Oct 01 15:03:03 <ingersol> packet 1143 with a lot of spin so yes could be on its way down
[13:06] <fsphil> yea you definitely bursted at about 15:00

[13:16] <eroomde> is the A560 still the defacto canon?
[13:17] <fsphil> the others seem to do as good a job from the pics I've seen
[13:17] <eroomde> yeah
[13:17] <eroomde> well, back in 2008 we started using them and chdk
[13:17] <eroomde> just wondering if there was a new '£40 from ebay' canon model
[13:18] <fsphil> I got two a560's for £20
[13:18] <eroomde> it seems like the quality of the glass drops as compacts get newer. i'd love to spend my money on a 4Mpx camera with better glass than a 12mpx with worse

[13:18] <eroomde> nice work
[13:18] <fsphil> was well chuffed
[13:18] <fsphil> naturally I destroyed both in the name of high altitude :)

[13:19] <eroomde> hmm i just had a look
[13:19] <fsphil> there's one ending in 6 hours
[13:19] <eroomde> the nikon d2h digital slr is 4mpx
[13:19] <eroomde> i bet it's a joy to use
[13:20] <Darkside> d2h?
[13:20] <Darkside> isnt that a full-frame DSLR?
[13:20] <eroomde> don't think so but not sure
[13:21] <eroomde> i was just thinking, if i wanted to get a digital slr (I do) i might go for that over something new
[13:21] <Darkside> heavy tho
[13:21] <Darkside> nah
[13:21] <eroomde> but... no prospect of that atm
[13:21] <Darkside> get a D5000 or something
[13:21] <Upu> sorry to be a pain my URL catcher is broken, I linked a pastebin yesterday with the tracker data in it anyone got that link, was sometime 8-10 last night
[13:21] <eroomde> yeah, the new slrs with HD video recording would be nice too
[13:21] <Darkside> 4Megapixels is a bit loooooow
[13:22] <SpeedEvil> http://pastebin.com/KuQL6PYr
[13:22] <SpeedEvil> tht?
[13:22] <eroomde> http://pastebin.com/KuQL6PYr
[13:22] <Upu> yup thx guys
[13:22] <eroomde> oh sorry iwas too slow

[13:24] <eroomde> i cannot tell you how seriously i looked at my overdraft allowances ^
[13:24] <Randomskk> haha
[13:24] <Randomskk> I bet
[13:24] <eroomde> it's such an adorably useful, wonderful machine
[13:25] <Randomskk> oh wow, 50Hz to 2.9GHz
[13:25] <eroomde> yup
[13:25] <eroomde> dc to daylight
[13:25] <Darkside> thats not DC to daylight
[13:25] <Randomskk> pedant
[13:25] <eroomde> there are so many things i could do with that
[13:25] <Darkside> we've got one of those at uni :P
[13:25] <Darkside> in my lab
[13:25] <Darkside> and it goes from DC to 30GHz
[13:25] <eroomde> i had one at my old work. it was a gem
[13:25] <eroomde> really useful for getting transfer functions
[13:25] <Randomskk> the engineering dept has a spectrum analyser in the eietl
[13:25] <Randomskk> it's super bad
[13:25] <Randomskk> http://www.flickr.com/photos/randomskk/5311113740/
[13:26] <Randomskk> none of the lab techs even knew how to use it or had seen it used
[13:26] <eroomde> did he donate it then?
[13:26] <Randomskk> nah, he let us use it for an experiment
[13:26] <eroomde> i suspect they give that to dodgy looking students who they don't trust with a decent one
[13:26] <Randomskk> but we had to give it back. expensive piece of kit
[13:26] <Randomskk> hah
[13:26] <Randomskk> you say that
[13:26] <Randomskk> our electronics lecturerer had to use it
[13:26] <Randomskk> lecturer even
[13:27] <eroomde> there are some decent ones up in edg
[13:27] <eroomde> but they are guarded by Davor the angry dog
[13:27] <Randomskk> he videoed himself using it to demonstrate something about audio amps or whatever, then played the video in lt0, amazingly his voice sounded exactly the same as when amplified on the speakers anyway
[13:27] <Randomskk> yea I bet
[13:27] <Randomskk> and I imagine CAPE has some very nice kit
[13:27] <Randomskk> this seems to be the jewel of the EIETL though
[13:27] <eroomde> oh god yeah
[13:27] <Randomskk> it can go up to like kilohertz
[13:28] <eroomde> :)
[13:28] <Darkside> wooooow
[13:28] <Darkside> incredible :P
[13:28] <Randomskk> and has a pen plotter output on the back
[13:28] <Darkside> we have a teaching lab at uni with about 20 cheap spec-ans in there
[13:28] <Darkside> DC to 3GHz ones
[13:28] <Darkside> tracking generators too
[13:28] <Darkside> we use them for final year pracs
[13:28] <Randomskk> :(
[13:29] <Darkside> they cost about $4k each i think
[13:29] <Randomskk> I like to imagine that if my final year project needed it they would have some available
[13:29] <Randomskk> seeing as every other uni I went to had hundreds of the things sitting on benches next to nice new scopes
[13:29] <Randomskk> then cambridge was like, we have a few super old analogue scopes, uh...
[13:29] <Darkside> i have to let final year students into that lab occasionally
[13:29] <Darkside> >_>
[13:30] <Darkside> am i right in saying that the university of adelaide has better undergrad equipment than CAMBRIDGE university?
[13:30] <eroomde> i love my analogue scope
[13:30] <eroomde> i'd like a storage one too though
[13:30] <Randomskk> probably not, but your electronics teaching lab might be better equipped :P
[13:30] <Darkside> everyone should start ont on an analogue scope
[13:30] <Randomskk> eroomde: I love my DSO
[13:30] <Randomskk> it's super handy
[13:30] <Darkside> then move to a DSO when they graduate
[13:30] <Darkside> :P
[13:30] <Randomskk> like on friday when I got my new (sound) amp but didn't have any speakers with which to try it
[13:30] <Randomskk> so I watched my music instead
[13:30] <Darkside> i've got a 15 year old tektronix 1GHz scope sitting in my lab
[13:31] <Darkside> maybe 10 year old
[13:31] <Darkside> but it has a floppy drive
[13:31] <eroomde> i might go for one of those rigol ones that the internet likes
[13:31] <Randomskk> haha yea, the company I worked for over christmas had an old HP with floppy drive
[13:31] <eroomde> the 50mhz ones which can be bumped to 100mhz
[13:31] <Randomskk> eroomde: they're cheap and appear to work nicely (plus that hack to.. yea)
[13:31] <eroomde> but... usually one can get by with an old analogue scope
[13:31] <Darkside> haha we have the rigols at uni :D
[13:32] <Darkside> the undergrad labs are half rigol, half tektronix TDS-1012s
[13:32] <Darkside> i HATE the rigols
[13:32] <Darkside> tektronics are way easier
[13:32] <eroomde> yes i was looking at the tek 210 on ebay
[13:32] <Randomskk> I kinda like my tenma, it's as easy as the tektronics in the lab
[13:32] <Randomskk> also it has coloured light up buttons
[13:32] <Randomskk> which is always nice
[13:32] <Randomskk> http://www.flickr.com/photos/randomskk/6197992835 etc
[13:33] <eroomde> you have crap music tastes
[13:33] <Randomskk> it's beautiful music
[13:33] <eroomde> oh yes you even admit to as much
[13:33] <eroomde> i beg your pardon
[13:33] <Darkside> haha
[13:34] <Randomskk> it turns out playing actual music made it much harder to check that the right channel was actually repaired
[13:34] <Randomskk> whereas I kinda know what sine waves should look like
[13:34] <Darkside> hmm i need to learn how to use a network analyzer properly
[13:34] <Darkside> since apparently i'm demonstrating one to some undergrads next week
[13:34] <Darkside> >_>
[13:34] <Randomskk> hah nice
[13:34] <Randomskk> plug in network, press analyse?
[13:34] <Randomskk> >_>
[13:34] <Darkside> Agilent 8714ET
[13:35] <Darkside> haha
[13:35] <Darkside> i'm teaching undergrads about antenna radio patterns
[13:35] <Darkside> we have this huge demo board thing, its a big metal sheet with a small loop antenna in the middle
[13:36] <Darkside> and a semicurcle of holes around the outside, and a monopole you stick in
[13:36] <Darkside> and you move it around and measure the radiation pattern
[13:36] <eroomde> complex?
[13:36] <Darkside> tbh i think you could do it with a spectrum analyzer
[13:37] <Darkside> eh?
[13:37] <eroomde> do you measure gain and phase?
[13:37] <eroomde> and if so how do you visualise it?
[13:37] <eroomde> just curious
[13:37] <eroomde> well, a tiny bit more than just curious but that's another convo
[13:37] <Darkside> that part isnt just complex, you're just measuring S21
[13:38] <eroomde> Randomskk: lol, just looking throuhg oyur flickr photos
[13:38] <eroomde> http://www.flickr.com/photos/randomskk/5401112061/in/photostream
[13:38] <Darkside> we just measure the transmission between the antennas
[13:38] <eroomde> the toughest balloon launch i have ever done
[13:38] <Randomskk> hah
[13:39] <Randomskk> god I've posted nearly no photos in two years at uni
[13:39] <Randomskk> sigh
[13:39] <Darkside> output a known carrier on one antenna, and measure the received power
[13:39] <Randomskk> third year looks to have a lot more non-lecture time at least
[13:39] <eroomde> Randomskk: imagine

[13:39] <eroomde> i used to be such a hacker before uni....
[13:39] <Randomskk> tell me about it, :(
[13:40] <eroomde> now i just think 'gaaaaaah... i've got actual work to do'
[13:40] <eroomde> so Randomskk - do you rate your scope?
[13:40] <eroomde> does it do any annoying things or are you basically happy?
[13:40] <Darkside> haha eroomde
[13:40] <eroomde> the screen looks quite sharp
[13:40] <Randomskk> happy with it, no annoyances really. beats out a lot of the scopes I've used in the dept
[13:41] <Darkside> i got more work done in the 1.5 months i was in the UK than i did in the preceding 3 months
[13:41] <Randomskk> haven't tried a rigol though
[13:41] <eroomde> it's about my (fictional) price range
[13:41] <Randomskk> being able to save screenshots to USB is nice
[13:41] <Randomskk> it can only do ten at once which is a bit annoying I guess
[13:41] <Randomskk> in theory it has a USB interface to your computer where you can remote control it and take screenshots, but
[13:41] <Randomskk> I think that needed windows software or something
[13:42] <eroomde> yeah
[13:42] <Darkside> yep, windows only afaik
[13:42] <Randomskk> I think in the end I decided that was the best I'd get for my price range and it's basically been really good
[13:42] <eroomde> we just got an agilent one at work
[13:42] <Randomskk> is it delicious
[13:42] <eroomde> with a vb scripting language to talk to it
[13:42] <Randomskk> oh
[13:42] <Randomskk> god
[13:42] <Randomskk> D:
[13:42] <Darkside> i almost go tht epoint of writing python software to talk to the tektronix's
[13:42] Gillerire (~Jamie@219-90-224-179.ip.adam.com.au) left irc: Quit: Quit
[13:43] <Randomskk> why do they make such nice hardware and then bollocks up the API so hard
[13:43] <eroomde> the problem with a spectrum analyser is that i sort of have one which really can do most of what i want with some cunning and bodgery
[13:43] <eroomde> it's called an ic-7000
[13:43] <Randomskk> hehe
[13:43] <Randomskk> it is a remarkable radio
[13:43] <Darkside> bahahah
[13:43] <eroomde> but, it would be so nice to have the testing abailities of the spectrum analyser
[13:43] <Randomskk> shame it tops out at 434mhz though
[13:43] <Darkside> i like my SDR-IQ
[13:44] <Darkside> i'd love to bring an IF tap out of the IC-7000 though
[13:44] <eroomde> there are so many things one wants to characterise the response of properly
[13:44] <Darkside> but itd void the lovely 5 year warranty
[13:44] <Darkside> andi have my Funcube dongle anyway
[13:49] <Darkside> bahahahaha
[13:49] <Darkside> i am responsible for 20% of these students prac grade
[13:50] <Darkside> so about 8% of their overall grade
[13:50] <eroomde> look at the caption
[13:50] <eroomde> http://www.flickr.com/photos/junkmatt/3215209508/
[13:50] <Darkside> BAHAHAHAHAHAHAH
[13:50] <eroomde> you just want to kill some people
[13:50] <Darkside> wait
[13:50] <Darkside> thats the one we have
[13:50] <Darkside> not 30GHz, 22GHz
[13:50] <Randomskk> how did it end up in scrap?!
[13:51] <Darkside> scary

[13:51] <Darkside> i'd like to make part of my SDR system a final year project
[13:52] <Darkside> but i'd be picking the students that do it..
[13:52] <Darkside> going from this eyars FYP crop, i doubt any would be able to do it
[13:52] wolfspraul (~wolfsprau@ joined #highaltitude.
[13:52] <Hibby> you'd be surprised
[13:52] <Darkside> no no no...
[13:52] <Darkside> i'm serious
[13:53] <Darkside> we've had some real idiots this year
[13:53] <Hibby> ours are *supposed* to be group projects, with each doing 400h work
[13:53] <Darkside> it was scary...
[13:53] <Hibby> that's a lot of free man hours
[13:53] <Darkside> heh
[13:53] Jasperw (~jasperw@2001:470:1f08:1caf::2) joined #highaltitude.
[13:53] <Darkside> well, in my case my main bit of hardware is going to be a small microcontroller based SDR
[13:54] <Hibby> most of our EEE students will graduate without ever having heard of an SDR
[13:54] <Darkside> heh
[13:54] <Hibby> as we have, really, very little in the way of RF education
[13:54] <Darkside> well i'm hoping we'll get one of the final year groups next year to design the next 3rd year radio project :P
[13:55] <Hibby> heheh
[13:55] <Darkside> moderately decent DDS, quadrature demodulator
[13:56] <Darkside> filters, then it goes into a PC
[13:56] <Darkside> or, we stick a usb sound card chip on the board
[13:56] <Darkside> kind of a poor mans funcube dongle
[13:56] <Darkside> but for HF only
[13:56] <Hibby> yeah, seems like a good starting point
[13:56] <Hibby> hmm... i've hit that complex juncture0 do i have a bowl of ricicles, or cook real food for lunch
[13:57] <Darkside> the idea was we get the students to do some construction of the board
[13:57] <Darkside> then we passe them off to signal processing lecturer to do some demodulation with it
[13:57] <Darkside> using either gnuradio or matlab
[13:57] <Darkside> gnuradio will be a pain with all windows PCs
[13:57] <Darkside> but i could probably make a small VM which they could use
[13:58] <Darkside> cut down ubuntu virtual machine with gnuradio pre-configured
[13:58] <Darkside> man that'd be fun
[13:59] <Darkside> must suggest that to my supervisor
[14:01] <Hibby> we're looking at VMs for servers
[14:01] <Hibby> I've managed to slip a project into 4th years this year for new motor controllers
[14:01] <Darkside> hahaa a friend of mine did that this year
[14:01] <Darkside> he made a very compact module for some national instruments thing
[14:02] <Hibby> as our controllers for the satellite station are fecked
[14:02] <Hibby> they're just terrible
[14:02] <Darkside> ooh are you back in the UK?
[14:02] <Darkside> clyde?
[14:03] <Hibby> Strathclyde Uni, still doing my thang, hopefully seamlessly transferring into "real world" work at Clyde Space over the next 9 months
[14:03] <Darkside> hehe
[14:03] <Hibby> but may go look for an "actual" job
[14:03] <Darkside> any idea how ukube-1 is going?
[14:04] <Hibby> we're about to start comms testing, but I only got that as I got a grumpy email saying "why haven't you been in to pick up your keys and pass:
[14:04] <Darkside> loll
[14:04] <Hibby> and I couldn't exactly reply, "mdma, cannabis and my little pony"
[14:04] <Darkside> bahahahhahhahaha
[14:05] <Hibby> so I had to say "yessir, nosir, three bags full sir"
[14:07] <Darkside> hehe
[14:07] <Darkside> we're getting toegher funds for a ground station in australia
[14:07] <Darkside> but i still don't know what hardware we need
[14:07] <Hibby> I can send you a list of everything we have up at STAC
[14:08] <Darkside> we have a 3.8m diameter dish sitting in the basement
[14:08] <Darkside> this for the 2.401GHz downlink?
[14:08] <Hibby> the main cost was our antenna set up, and IC910H radio
[14:08] <Hibby> nah, this is U/V
[14:08] <Darkside> bah
[14:08] <Darkside> we've already got that fine
[14:08] <Hibby> we're likely only going to have a basic microwave capability
[14:08] <Darkside> we're gonna use a FCD
[14:08] <Hibby> as there's nae funding for what we really want
[14:08] <Hibby> :)
[14:09] <Darkside> so RAL is going to be the only downlink?
[14:09] <Darkside> i mean, only s-band ground station?
[14:09] <Hibby> currently, aye, afaik
[14:09] <Hibby> EADS
[14:09] <Darkside> jeez
[14:09] <Darkside> could you find out what gear they have?
[14:09] <Hibby> will look into it, aye. Shouldn't be too hard.
[14:10] <Hibby> our limitation is the space for the dish/array and getting the H&S passed for it to be there
[14:10] <Darkside> yeah, we're looking at putting ours out in department of defence site
[14:10] <Hibby> took 3 months from original antenna install before the uni actually got estates to run the cabling for us
[14:10] <Darkside> hahahahahahaha
[14:10] <Darkside> y'know how we solved that problem?
[14:11] <Darkside> we did it ourselves and didn't tell them
[14:11] <Hibby> and i got in massive shit becuse I had run my own in the meantime
[14:11] <Darkside> heh
[14:12] <Hibby> man, im so keen to do power use monitoring in this flat
[14:12] <Hibby> but I've just not been able to find a suitable clamp meter
[14:12] <Hibby> I want something that'll output xV/xW or xV/xI or something
[14:13] <Hibby> then it's a piece of piss to measure and output

[15:39] <RocketBoy> ah OK - i'll give it a try - would my A560 handle it?
[15:39] <fsphil> mac should be able to handle that
[15:39] <fsphil> should just appear as two disks
[15:41] <Upu> yep
[15:41] <Upu> just hit write protect
[15:41] <Upu> boot up
[15:41] <daveake> I'm confused ... why does an 8GB card need 2 partitions? Is it because it's SD not SDHC?
[15:41] <RocketBoy> just cleaning the contacts as the gold is showing signs of rust deposits
[15:41] <Upu> in chkd under misc its switch parttitions
[15:42] <daveake> So is it a boot partition for CHDK plus separate one for the photos?
[15:43] <fsphil> yea
[15:43] <daveake> gottit
[15:43] <Upu> yep
[15:43] <fsphil> chdk needs a fat16 partition
[15:43] <fsphil> which is limited by how big it can get
[15:43] <daveake> Ok. I've not tried the autoboot yet.
[15:43] <Upu> write protect currently isn't switched as my camera had issues with it
[15:43] <RocketBoy> woo mac tis loading photos - so it says

[15:49] <Upu> but whilst your doing that upload that to imageshack pretty pls :)
[15:49] <daveake> *Upu trying but failing to remain calm ;)

[15:51] <Upu> 2800 !?
[15:51] <Upu> jesus
[15:51] <fsphil> good count
[15:51] <daveake> Sounds like an excellent result
[15:51] <RocketBoy> thats what it says
[15:51] <fsphil> I got hundreds of pics of trees
[15:51] <RocketBoy> yep - worked fine all the way down and in the water
[15:52] <Upu> do realise that means the camera was taking pictures for just short of 8 hours
[15:52] <Upu> and in the water for 5
[15:52] <RocketBoy> the sea wa like a mill pond
[15:52] <fsphil> how often where you talking pics Upu?

[16:04] <SpeedEvil> I mean the ad-selection
[16:04] <Dan-K2VOL> ha it gave me two ads in español
[16:05] <Dan-K2VOL> perhaps their ad server is borked today
[16:05] <Upu> Looks like Ava's camera carried on clicking way into the night

[16:08] <Upu> these are bigger res from the camera ?
[16:08] <Dan-K2VOL> rocketboy do you have a website for your flight?
[16:08] <RocketBoy> suggest that it might not have been too deep as the chute had a lot of mud in iit

[16:18] <Dan-K2VOL> darn our planet having so much clouds all the time. Have any of you noticed how sci-fi movies from before the space era usually show the earth nearly devoid of clouds?
[16:18] <jcoxon> good point :-)

[16:25] <RocketBoy> OK - ill see if there is any video
[16:26] <RocketBoy> if I can find my adaptor
[16:27] <Upu> it will be in 4 lots of 2Gb each
[16:28] <Upu> Well I've been going through the data
[16:28] <RocketBoy> ok Np - finding the micro SD adaptor will be the chanenge
[16:29] <Upu> and I think thats 32-34k alt
[16:29] <Upu> unless anyone thinks it looks higher
[16:29] <RocketBoy> Its with my G8 SD card - where ever that is
[16:29] <Upu> no rush :)

[16:37] <Upu> the caribina is mine btw :)
[16:38] <Upu> looks like a clean burst

[16:38] <Dan-K2VOL> hahaha
[16:40] <Upu> Was the GPS antenna still connected RocketBoy ?
[16:40] <Upu> can't see any reason why it wouldn't be
[16:42] <Upu> can see a big blog post coming this evening
[16:45] <RocketBoy> Upu: yes the GPS antenna is still attached
[16:45] <Upu> odd
[16:45] <RocketBoy> its a small bit wibbbly wobbly in the socket - but was probably OK
[16:46] <RocketBoy> did notice that the antenna was quite close to the polystyrene
[16:47] <number10> Upu looks like there are two payloads?
[16:48] <RocketBoy> upu - just looked - where the co-ax enters the antenna block - t looks like the shield is broken away
[16:57] <Upu> ah
[16:57] <Upu> that would explain it

[17:13] <RocketBoy> I think all the ones we dont get back end up floating to the sargasso sea - I'd like to think that anyway
[17:14] <daveake> Maybe somewhere there's a small collection of payloads keeping each other company
[17:14] <RocketBoy> yeah
[17:15] <daveake> If mine had still been transmitting I'd have gone looking for a boat. As it was, with the last position being 500m up, I didn't want to waste my helpers' time
[17:16] <RocketBoy> todays recovery didn't come cheap - £100 for the rib hire
[17:17] <daveake> I'd have been willing to paid a bit more if I was reasonably sure of a recovery

[18:25] <Upu> http://imagebin.org/177126
[18:25] <Upu> how high ?
[18:25] <Dan-K2VOL> sky high
[18:26] jcoxon (~jcoxon@ joined #highaltitude.
[18:26] <SpeedEvil> It should be possible to work it out
[18:26] <SpeedEvil> Neglecting curvature of light.
[18:26] <Upu> ah jcoxon you have some experience
[18:26] <Upu> http://imagebin.org/177126
[18:26] <Upu> how high ?
[18:26] <Upu> I'll take the average of all your guesses :)
[18:26] <fsphil> guessing about 36km
[18:26] <jcoxon> could you calc it by triganometry
[18:27] <SpeedEvil> The horizon is a circle.
[18:27] <Dan-K2VOL> give us the lens you used and we'll give you a better answer
[18:27] <Upu> Canon A560
[18:27] <Upu> whatever that has on it
[18:27] <jcoxon> Upu we have an inital ascent rate don't we
[18:27] <SpeedEvil> Its diameter is found by altitude.
[18:28] <jcoxon> can't we calc off the number of photos
[18:28] <Upu> yeah good point
[18:28] <SpeedEvil> hmm
[18:28] <Upu> I'll wait till I get them back
[18:28] <jcoxon> as in we can calc the time into flight of the photo
[18:28] <jcoxon> then using the inital ascnet rate which doesn't change that much
[18:28] <fsphil> won't work if it floated though
[18:28] <Upu> it was a little low
[18:28] <Upu> so i don't trust it
[18:29] <Upu> 3m/s
[18:29] <Upu> Steve said the antenna sheild cable was loose/damaged
[18:30] <SpeedEvil> You need to convert and remove any lens distortion, work out what the curvature of the horizon is, go backwards from that to the circumference of the circle relative to a flat horizon, then do some trig to get to the height
[18:30] <SpeedEvil> It should be fairly straightforward, but I'm not doing it
[18:31] <Upu> lol
[18:31] <Dan-K2VOL> ha ditto
[18:31] <Dan-K2VOL> the program hugin would help
[18:31] <SpeedEvil> Or yeah - screw around in google earth for a bit going 'hmm - that sorta looks like it'
[18:31] <Upu> I did
[18:31] <Upu> 37km
[18:31] <SpeedEvil> Sounds not implausible
[18:32] <SpeedEvil> That's the top?
[18:32] <Upu> probably a little lower
[18:32] <daveake> Lens will make some difference
[18:32] <Upu> I'll call it 34km ish
[18:32] <fsphil> my own pics with the a560 showed very little curvature. that was about 31km
[18:33] <fsphil> there's a definite curve in that shot
[18:33] <Laurenceb_> http://imagebin.org/177123
[18:33] <Laurenceb_> wait what
[18:33] <SpeedEvil> That's an uncropped shot?
[18:33] <Laurenceb_> how did you get it back?
[18:33] <SpeedEvil> The above pic of the horizon, not Laurenceb's one
[18:33] <daveake> Photograph something rectangular and check :-). Modern lenses are pretty good though.
[18:34] <SpeedEvil> The one Laurenceb linked is awesome too though. :)
[18:34] <Upu> Laurenceb that is the secondary payload that was suspended below Ava on the water

[18:52] <Dan-K2VOL> Hi SamSilver
[18:53] <jcoxon> SamSilver, yes
[18:53] <SamSilver> i am having the same debate
[18:53] <SamSilver> Hi Dan
[18:53] <Dan-K2VOL> SamSilver you should look at the Delorme InReach
[18:53] <jcoxon> SamSilver, also the setup means that people need to hand decode the data
[18:53] <Dan-K2VOL> that's not good
[18:53] <Dan-K2VOL> don't have ppl hand decode, if you can avoid it
[18:53] <SamSilver> the "social" side of the rate of Tx
[18:54] <SamSilver> how to keep listeners interested
[18:54] <jcoxon> Dan-K2VOL, thats the issue -getting everything to be 25g means that i've been unable to use RTTY
[18:54] <jcoxon> instead have hellschreiber and morse
[18:54] <SamSilver> yes jcoxon
[18:54] <Dan-K2VOL> oh, morse is computer decodable
[18:54] <jcoxon> its terribly decoded
[18:54] <Dan-K2VOL> ah
[18:55] <SamSilver> I am a morse code on 40m or 20 m for my long duration
[18:55] <Dan-K2VOL> could use a simpler OOK method like RC planes used to use, like Pulse Width Modulation, or Pulse Position Modulation

[18:55] <jcoxon> everytime he beat me
[18:56] <jcoxon> and i'd record it and run it multiple times
[18:56] <Dan-K2VOL> haha yeah a human seems to always be better
[18:56] <jcoxon> hellschreiber is awesome though
[18:56] <Dan-K2VOL> I've thought about going to morse for long duration superpressure too
[18:56] <jcoxon> just read it off
[18:56] <jcoxon> type it in
[18:56] <Dan-K2VOL> it's still not computer decodable, but I suppose it's accessible for more listeners
[18:56] <SamSilver> jcoxon: I am a olivia data fan
[18:57] <Dan-K2VOL> talking about single tone modes
[18:57] <jcoxon> Dan-K2VOL, truthfully picoatlas3 could be a good long duration payload
[18:57] <Dan-K2VOL> nice!
[18:57] <jcoxon> 27g currently
[18:57] <jcoxon> and in theory able to run indefinitely as long as the sun pops out
[18:57] <Dan-K2VOL> the UCAR GHOST series just used solar powered morse most of the time
[18:57] <Dan-K2VOL> nice work
[18:57] <jcoxon> i've got solar+110mAh Lipo
[18:57] <fsphil> jcoxon, if the caa give me my notam on time I may do a floating launch in your general direction next weekend
[18:57] <Dan-K2VOL> very nice jcoson
[18:58] <jcoxon> mass 14.9g
[18:58] <jcoxon> the problem right now is balancing everything
[18:58] <Dan-K2VOL> what voltage
[18:58] <SamSilver> jcoxon: 27g and 20+ hours duration ?? you are just plain showing off !! :p
[18:58] <jcoxon> Dan-K2VOL, 3.7v
[18:58] <jcoxon> but at full charge 4.2v
[18:58] <SamSilver> AFK
[18:58] <jcoxon> SamSilver, from dead it takes about 2hrs in the morning to be funcitoning again
[18:58] <Dan-K2VOL> that's very low for all the ballon HF transmitters I've had
[18:59] <jcoxon> its not HF
[18:59] <Dan-K2VOL> nice
[18:59] <Dan-K2VOL> ahhh
[18:59] <Dan-K2VOL> gotcha
[18:59] <jcoxon> Dan-K2VOL, i'm not allowed to play with HF
[19:00] <SamSilver> jcoxon: you mean it is repeatable? Tx ... sleep .... wake up and the Tx again ??
[19:00] <jcoxon> well thats what it does
[19:00] <jcoxon> but i mean over night the lipo runs down
[19:00] <SamSilver> jcoxon: you and I are never going to be freinds! :p
[19:00] <jcoxon> and when the sun comes up it powers up again
[19:00] <SamSilver> what with your hacked spot
[19:01] <jcoxon> no this is all radio
[19:01] <jcoxon> 434mhz
[19:01] <Dan-K2VOL> and overnight the lipo will freeze
[19:01] <SamSilver> and now your nano Power Tx
[19:01] <jcoxon> Dan-K2VOL, oh yes
[19:01] <Dan-K2VOL> but it will recover in the heat of the sun
[19:01] <SamSilver> I am now AFK wife says I must cook
[19:02] Nick change: SamSilver -> SamSilver_
[19:02] <jcoxon> Dan-K2VOL, i don't think i could make it much smaller
[19:02] <Dan-K2VOL> by the way, http://en.wikipedia.org/wiki/Silver_sulfide Silver Sulfide is amazing stuff for absorbing solar heat
[19:02] <jcoxon> without a pcb

[19:03] <jcoxon> Dan-K2VOL, if it actually works (which i doubt hehe) i'll ship one for your hackspace
[19:04] <Dan-K2VOL> that'd be great!
[19:04] <Dan-K2VOL> when do you think you may launch next?
[19:04] <jcoxon> when i crack this
[19:04] <jcoxon> i'm thinking in a few weeks
[19:04] <Dan-K2VOL> cracking the telemetry?
[19:05] <jcoxon> cracking the powersaving
[19:05] <jcoxon> basically i have to power the gps up and down
[19:05] <Dan-K2VOL> ahh yeah
[19:05] <jcoxon> pressure sensor onboard for regular pressure data
[19:05] <jcoxon> so we can monitor float
[19:05] <Dan-K2VOL> nice, you could fly with no gps and only pressure for testing
[19:05] <jcoxon> but i'm working out how often i can power up the gps
[19:05] <jcoxon> just for location
[19:06] RocketBoy (~steverand@5acfd4f7.bb.sky.com) left irc: Read error: No route to host
[19:07] <jcoxon> the other thing is that in theory it can do 20dbm
[19:07] <Dan-K2VOL> tx power?
[19:07] <jcoxon> yeah
[19:07] <jcoxon> in theory
[19:07] <jcoxon> so in the UK run it at 10 dbm
[19:08] <jcoxon> but once we leave the area...
[19:08] <Dan-K2VOL> ahh nice idea
[19:09] <jcoxon> will write it up soon

[19:34] <Upu> Dave ?
[19:34] <costyn> :)
[19:34] <daveake> Josh_ Since your payload saved Upu's, I think he should payt for that beer :)
[19:34] <Upu> I bought him his tea last night :)
[19:34] <Upu> but yeah I owe you one
[19:34] <Josh_> Nah it's part of the fun!
[19:35] <Josh_> Ed
[19:35] <Upu> thanks
[19:35] <Josh_> Anthony was a top bloke to work with!
[19:35] <Upu> cheers Josh was fun working with you too
[19:36] <Upu> can you get a screen shot of the upward facing camera ?
[19:37] <Upu> http://ava.upuaut.net/?p=155
[19:37] <Upu> looks like I nicked the GPS antenna cable when I assembled the payload and damaged it slighly Josh
[19:37] <daveake> That is a very good shot
[19:38] <daveake> Stuff like that is very easy to do Upu
[19:38] <Upu> sticker on the Energizer batteries says 680 photos
[19:38] <Upu> lol
[19:38] <Upu> more like 2800 :)
[19:39] <daveake> lol
[19:39] <daveake> Yeah, the 680 is with average amount of on/off and zooming and with the screen on
[19:40] <Josh_> hahahaha
[19:40] <Josh_> ahhhh dear
[19:40] <Josh_> i'll get a couple of snapshots down and upload the,
[19:40] <Upu> thanks
[19:40] <costyn> Upu: so you didn't end up installing your pyro cutdown right?
[19:41] <Upu> no I have no method to trigger it the code however was there for testing
[19:41] <Upu> however as AVA had no location data it didn't work
[19:42] <costyn> Upu: ok; the devices you showed being tested on your site weren't usable in the balloon yet
[19:42] <costyn> Upu: and yea, you do need gps data to use it :)
[19:42] <Upu> they are usable but I don't have the electronics in the balloon to trigger them
[19:43] <daveake> What happened with RocketBoy's cutdown?
[19:43] <Upu> my criteria for triggering is altitude > 10000 and based on rate of (de/ac)accent
[19:43] <SpeedEvil> costyn: Sort-of. It could cutdown on no GPS too
[19:44] <Upu> you can have timed cut downs
[19:45] <daveake> On mine I had a descent-check and also a timeout. The latter kicked in first. I didn't have a cutdown connected though.
[19:45] <costyn> ok; trying to figure out if I want a cutdown mechanism on ours. it seems like a really good idea with all these balloons falling into the sea lately, but on the other hand the code and mechanism are complicated too
[19:45] <Josh_> http://imageshack.us/f/842/vlcsnap2011100220h42m09.png/
[19:46] <costyn> Josh_: nice

[19:46] <costyn> Josh_: is that white fleck the moon or ... ?
[19:46] <Josh_> got our moon in there!
[19:46] <daveake> Cutdown wouldn't have saved mine - it wasn't going anywhere when it was (nearly) floating.
[19:46] <Josh_> yeahhhh was looking gorgeous
[19:46] <Upu> thats AVAs bottom :)

[20:55] <fsphil> haha, yea wasn't expecting that
[20:57] <fsphil> lovely strong signal from mondo, but the pauses during the lines where a bit annoying
[20:58] <Upu> he had long pauses ?
[20:58] <fsphil> it would pause before certain items
