[08:33] <jcoxon> strange - for some reason my payload has a different shift on my linux dl-fldigi to my mac dl-fldigi
[08:34] <jcoxon> same radio
[08:34] <mattltm> odd
[08:34] <jcoxon> it decodes fine on my mac but not on linux
[08:34] <jcoxon> even after i expand the shift
[08:35] <mattltm> that is strange.
[08:36] <mattltm> RV button?
[08:36] <jcoxon> i'm wondering if its a timing issue
[08:36] <jcoxon> nah both are the same and toggling it doesn't make a difference

[08:41] <fsphil> jcoxon, sample rate of the capture card
[08:45] <fsphil> that would affect both baud rate and shfit
[08:51] <jcoxon> bingo
[08:51] <jcoxon> switch it back to oss
[08:53] <jcoxon> now its working
[08:58] <daveake> Good call!
[09:04] <jcoxon> i'm enjoying trying to get this powersaving to work
[09:05] mixio (~mixio@ppp046177219063.dsl.hol.gr) joined #highaltitude.
[09:06] <daveake> Sounds like it! I always like a challenge too.
[09:06] <jcoxon> the current setup seems to be able to rescue itself from complete power loss
[09:06] <jcoxon> if its in bright sun light
[09:06] <daveake> What's the project for?
[09:07] <jcoxon> daveake, its a micropayload
[09:07] <jcoxon> < 100g
[09:08] <daveake> Ah, OK, so less than my batteries weigh ;-)
[09:08] <jcoxon> this one currently weighs 40g
[09:08] <jcoxon> though a smaller solar panel would drop it to 32g
[09:09] <daveake> So it's GPS + processor + small battery + solar panel for 40g?
[09:09] <jcoxon> and radio
[09:09] <jcoxon> yeah
[09:09] <daveake> Of course, I forgot! Very impressive.
[09:11] <jcoxon> it does mean that you can't have it continously transmitting :-)
[09:12] <daveake> Indeed!
[09:12] <daveake> Even my GPS antenna (a mag mount one) weighs more than that. My target was <1kg for everything below the balloon, and the big items are the cameras, phone and batteries.
[09:13] <jcoxon> oh yeah don;t worry
[09:13] <fsphil> it's difficult once you get below 500g when also including cameras
[09:13] <jcoxon> your payload mass is good
[09:13] <daveake> I ditched the phone as I hit the Arduino's memory limit when I included the code for that, so instead I'm using a separate GPS/GSM tracker
[09:13] <daveake> Next time I'll switch to an Arduino Mega. I have one in front of me but I don't want to make any last-minute changes :-)
[09:13] <fsphil> wise words
[09:14] <daveake> I know LOL
[09:14] <fsphil> aah see you're on the tracker
[09:14] <daveake> Indeed, thanks to jcoxon here :-)
[09:15] <fsphil> any idea what happened spacenear.us last night jcoxon?
[09:15] <daveake> He killed it ;-)
[09:15] <jcoxon> nope
[09:15] <jcoxon> momentary loss
[09:16] <daveake> My antenna doesn't have a great view of the sky as it's dangling in a half-open window, so the location is bouncing around a little more than I'd expect. My house is the one to the left of the balloon, if you switch to satellite view
[09:17] <fsphil> the gps seems to vary a lot when the unit is standing still
[09:18] <jcoxon> yeah gps drift is normal
[09:18] <jcoxon> once its moving its bit better
[09:18] <daveake> Also it's only got 4 sats because of the view
[09:19] <daveake> On the assumption that my GPS will crap out above 60,000 feet, what normally happens to the NMEA stream? All zeroes, or does it lock in the last reading?
[09:20] <jcoxon> daveake, what gps is it?
[09:20] <jcoxon> as the response varies
[09:20] <daveake> Navman Jupiter 11
[09:20] <daveake> It's olde
[09:20] <daveake> But free
[09:20] <jcoxon> it'll probably just not have a lock
[09:21] <daveake> I have an SCP1000 pressure sensor in there too, so hopefully I'll know how high it got.
[09:21] <daveake> Next time I'll get a GPS that is known to work.
[09:22] <jcoxon> life is made easy with a newer gps
[09:22] <daveake> I bet
[09:22] <jcoxon> as you don't wait so long for a lock
[09:22] <daveake> I just felt it deserved to get used.
[09:22] <daveake> Before I bin it :-)
[09:23] <daveake> One of my customers wants to sponsor a launch so next time the budget will be larger too :)
[09:23] <fsphil> nice
[09:25] <daveake> Actually, they've offered to pay for the balloon and helium for this one too, which helps as those are the more expensive bits.
[09:25] <jcoxon> indeed
[09:26] <fsphil> and (hopefully) the only bit that can't be re-used
[09:26] mixio (~mixio@ppp046177219063.dsl.hol.gr) left irc:
[09:27] <daveake> Hopefully :-)
[09:27] <daveake> Well, I'm expecting the antenna wire to need replacing ;-)
[09:27] <fsphil> the one advantage of landing in a tree, mine survived :)
[09:30] <daveake> LOL
[09:30] <daveake> OK, about to be dragged off to the shops. I need some OS maps for the expected landing area :-)
[09:31] <jcoxon> sweet my payload has now been running for 1 hour
[09:31] <fsphil> same teeny battery?
[09:31] <jcoxon> yeah

[10:23] <cuddykid> jcoxon: is the aim with picoatlas altitude or just seeing how light you can make a payload?
[10:23] <cuddykid> I'm guessing you could get some serious altitude with it!
[10:24] <jcoxon> partially
[10:24] <jcoxon> its also an experiement with other types of balloons
[10:24] <jcoxon> such as foil balloons
[10:24] <cuddykid> ahh right, cool
[10:24] <jcoxon> its also a good exercise in coding

[14:46] <fsphil> 10m is nice if conditions allow it#
[14:46] <Darkside> what antenna do you have for 40?
[14:46] <fsphil> vertical
[14:46] <Darkside> hmm, D layer will be pretty bad over there
[14:46] <Darkside> i guess we can try, i have a pretty decent 40m antenna here
[14:47] <mattltm> I have 40M H broadside to the US.

[14:50] <Darkside> pretty bad here too
[14:50] <fsphil> I doubt I'd even hear a nearby station atm
[14:50] <Darkside> also theres some dodgy data transmissions around 40m atm
[14:51] <Darkside> like, wideband digital stuff

[14:54] <fsphil> hear some stuff on 20m but it's pretty faint

[14:56] <Laurenceb_> how do i get round problems linking to a datatype from multiple files?

[16:45] <SamSilver> I made my own yagi
[16:45] <SamSilver> what freq?
[16:46] <SamSilver> made 4
[16:46] <SamSilver> afk
[16:47] <chris_99> could you get one that does a large band, 0.5 to 1400MHz
[16:47] <chris_99> or is that not possible

[16:50] <SamSilver> chris_99:
[16:50] <SamSilver> where to start
[16:51] <SamSilver> ....
[16:51] <chris_99> heh
[16:52] <SamSilver> it is such a big subject that you need to read more about it be fore you ask questions that are to big for a quick answer

[17:05] <chris_99> i was thinking of using http://www.radiometrix.com/content/afs2-0 so i'll get one thats near 458MHz

[17:44] <chris_99> yeah its awesome :)
[17:50] <cuddykid> chris_99: got mine from LPRS from memory - works a treat
[17:51] <chris_99> that NX one i linked too?
[17:51] <cuddykid> there's a case study featuring their yagis for HAB projects on their website
[17:51] <cuddykid> urm, not sure, I'll get you link
[17:51] <chris_99> thanks
[17:52] <cuddykid> this is the one I have (and WillDuckworth has) - http://shop.lprs.co.uk/product_info.php?products_id=108
[17:52] <cuddykid> works great
[17:52] <cuddykid> WillDuckworth: how's the payload progressing?
[17:53] <chris_99> cool :)
[17:53] <WillDuckworth> hi, near enough nailed arduino/gps/transmitter, still persevering with the sstv stuff
[17:53] <cuddykid> nice, oooo trying sstv on flight too?
[17:54] <WillDuckworth> defo, trying to get it all perfect, test test test
[17:54] <cuddykid> nice!!
[17:54] <cuddykid> btw, have you heard of my wacky idea that I'm planning - fireworks in space?!
[17:55] <WillDuckworth> thinking either 23rd, or 30th.... yeah, heard, might look good :)
[17:55] <cuddykid> if it's the 30th I can help track etc :)
[17:55] <WillDuckworth> maplin had some remote firework igniter thing a while back i saw...
[17:55] <cuddykid> oh right, I'll take a look
[17:56] <cuddykid> currently, just planning on some nichrome near the fuse of rocket
[17:57] <cuddykid> looking into seeing if I can remotely activate video on canon with usb (I think I can!); also, bought a cheap (£4) keychain video cam
[17:57] <SamSilver> oohh a cathrine wheel at 136K
[17:58] <SpeedEvil> That's an expensive catherine wheel!
[17:58] <SamSilver> LOL
[17:58] <chris_99> make sure to have a camera pointing up to capture the display cuddykid
[17:58] <cuddykid> SamSilver: haha
[17:58] <daveake> cuddykid re USB on Canon, yes you can. See http://chdk.wikia.com/wiki/USB_Remote_Cable
[17:58] <cuddykid> chris_99: yeah, that's going to be really hard, think luck will play a large part!
[17:59] <cuddykid> daveake: yeah, been reading that :) thanks
[17:59] <daveake> Also see http://stereo.jpn.org/eng/sdm/index.htm
[17:59] <cuddykid> thanks!
[18:00] <cuddykid> that's pretty awesome
[18:00] <daveake> I'm pretty sure that the guy who does those "Matrix" style things for TV and movies uses just this, with 60 or 80 cameras
[18:01] <SamSilver> http://spacebits.eu/page/camera.html
[18:01] <cuddykid> my problem is that the camera will be running a script to take a photo every ~ then, when triggered by arduino (just before ignition) - it needs to be overwrited and start filming
[18:02] <SamSilver> cuddykid:
[18:02] <SamSilver> SIMPLE SOLUTION
[18:02] <SamSilver> GET TWO CAMERAS
[18:02] <SamSilver> oops
[18:03] <SamSilver> caps
[18:03] <SamSilver> realy at $4
[18:03] <daveake> maybe you can test the usb from a script?
[18:03] <SamSilver> get 4
[18:03] <daveake> :)
[18:03] <SamSilver> how much do they weigh?
[18:04] <daveake> That's what I have in cloud1 - Canon camera doing stills @5 second intervals roughly, and Kodak videocam doing the HD video. Simple simple simple :-)
[18:04] <cuddykid> SamSilver: problem is I don't think the £4 ones will work (due to lipo batteries and it will have to be reasonably exposed to the -50ish temps
[18:04] <cuddykid> daveake: yeah, was trying to avoid getting another cam though
[18:05] <daveake> I think I remember that you can check usb in the chdk that the stereo guys modify. Check that stereo site. Then you can have a script that changes operation when the arduino says so

[18:09] <daveake> and more gaffer tape LOL
[18:09] <cuddykid> you'll be fine! I never thought I'd be able to do it but managed (well, with the help of Will!)
[18:09] <cuddykid> yeah, I got through about 8m of duct tape lol
[18:09] <daveake> Mrs Dave has sewn lines into the parachute so I can attach it to the balloon
[18:09] <WillDuckworth> that's the easy bit.... ;) have you got patent pending on that contraption cuddykid?
[18:10] <cuddykid> lol WillDuckworth!!
[18:11] <daveake> Need to reload chdk onto the SD card, then find my list of steps to start the script without saving raw files or doing anything else "sub-optimal" ;-)
[18:12] <cuddykid> ooo.. just found out chdk people have an irc channel.. feel like popping on and telling them about how their arbitrary limit of 999 999 managed to result in 0 photos being taken!!
[18:12] <daveake> LOL
[18:12] <cuddykid> daveake: haha, yeah, do not touch the script lol
[18:12] <daveake> Give 'em grief!
[18:13] <daveake> The ONLY thing I'm changing is I need to add a bit to the Arduino to switch on my buzzer and flashing LED when it lands. Even that simple thing scares me at this late stage!
[18:13] <cuddykid> lol, my change was even simpler and it had bad consequences!
[18:13] <daveake> I have a rule when I'm on-site with customers - "no changes on the last day". I try to stick to it but sometimes ...
[18:13] <daveake> I know!!!
[18:14] <cuddykid> daveake: be careful, it took me a lot of debugging when I had to code in to set buzzer off - started interfering with my gps stuff - never anticipated it!
[18:14] <daveake> I hear you :-)
[18:14] <cuddykid> haha
[18:14] <daveake> Maybe just connect them direct to the battery, and use a bigger battery!
[18:15] <cuddykid> could do!

Well, it isnt. The device provides a high-level interface to the memory card, but in doing so the makers just made things more complex not less. They also forgot to document the thing properly. The result was several wasted hours before I consign
[20:39] <daveake> Yep. Previously I used it with an IXUS 50 and that just needed "set_backlight(0)" or similar. The A480 needs the plug

[20:48] <eroomde> we made a balloon tracker back in the day, pre spacenear.us - it might make a good basis for an offline tracker for chase cars

[20:49] <eroomde> vintage 2006
[20:50] <Upu> that doesn't look very big ? :)
[20:50] <eroomde> (do excuse me, I'm having a moment with all these old images on a random folder on our web server)
[20:50] <eroomde> no it was very wee!
[20:50] <chris_99> cheers :), Upu
[20:50] <Upu> no problems :)
[20:50] <Upu> old school is good eroomde
[20:50] <eroomde> it's amazing how much better everthing is now
[20:50] <eroomde> spacenear.us is the Best Thing Ever
[20:51] <Lunar_Lander> yeah
[20:51] <Upu> who actually runs that site ?
[20:51] <eroomde> natrium
[20:51] <Upu> ah ok
[20:51] <eroomde> http://www.srcf.ucam.org/~cuspaceflight/images/ears2before.jpg
[20:51] <eroomde> iain and I with rocket v1
[20:52] <eroomde> 2007 i think
[20:52] <Upu> you launched that from a balloon ?
[20:52] <griffonbot> @LVL1WhiteStar: Electronics all bolted on for SpeedBall-2 ! Next is firmware loading. #arhab #UKHAS #MakerFaire http://t.co/7fjlE9u [http://twitter.com/LVL1WhiteStar/status/89799169455304704]
[20:52] <eroomde> proof that balloons get bigger: http://www.srcf.ucam.org/~cuspaceflight/images/balloon_comparison.jpg
[20:52] <eroomde> that was a ground launch
[20:53] <eroomde> that was just to build a first rocket to get the ball rolling
[20:53] <Upu> k
[20:54] <eroomde> this was the platform that launched that little rockoon: http://www.srcf.ucam.org/~cuspaceflight/images/FEAModel.jpg
[20:54] <eroomde> the the rockoon sat in the tube
[20:54] <Upu> did it fire down ?
[20:54] <eroomde> got a massively boosed acceleration because of the gas pressure behind it (it sat on a piston)
[20:54] <eroomde> and we had three parachutes, apollo style, mortar launched in those three smaller tubes
[20:55] <Upu> I'd love to launch a rocket from a balloon
[20:55] <eroomde> and the big flat disc was an air-brake so it could free-fall safely after rockoon launch
[20:57] <eroomde> Upu: me too
[20:57] <eroomde> it's the ultimate thing to do once you're up at 30km I think
[20:57] <eroomde> hopefully we will soon
[20:58] <Upu> yeah would love to see that
[20:58] <Upu> hell even do it
[20:58] <Upu> one step at a time :)
[20:58] <eroomde> yep
[20:58] <eroomde> it's at the stage that hab was at 5 years ago
[20:59] <eroomde> everything was difficult and usually failed the first couple of times
[20:59] <Upu> the electronics are getting better too
[20:59] <Upu> cheap fast accelerometers and positional sensors
[20:59] <eroomde> i'm much much happier that we can do more complicated computer controlled things since we did the ESA work
[21:00] <eroomde> sequencing complicated pyrotechnics in very dynamic conditions, etc
[21:00] <Upu> So many things to consider
[21:00] <eroomde> it's just a question of getting a good launch now, I think
[21:00] <Upu> be a real project
[21:00] <eroomde> it's the main aim of cusf
[21:00] <Upu> whats the legality of it all
[21:00] <eroomde> that's why we haven't really done many balloon launches in the last year or two
[21:01] <eroomde> focus has been on rockets
[21:01] <eroomde> oh, v illegal in britain
[21:01] <Upu> you can't get like a NOTAM for it ? :)
[21:01] <eroomde> you need either a range (like yuma, wallops, esrange, woomera or something) of a country with no laws
[21:01] <Lunar_Lander> eroomde could you please give me the link again for the ExoMars test?
[21:01] <Upu> "high altitude eratic uncontrolled rocket launch" :)
[21:01] <Upu> ok
[21:02] <eroomde> Lunar_Lander: http://www.eng.cam.ac.uk/news/stories/2011/CU_Spaceflight/
[21:02] <Lunar_Lander> thanks
[21:02] <Upu> how high do you reckon a rocket you could get up there would go if it was launched from 30k ?
[21:02] <eroomde> 100km
[21:02] <eroomde> that's what we're working on
[21:02] <Upu> seriously ?
[21:02] <eroomde> no point not going to space, right?
[21:03] <eroomde> yes totally seriously
[21:03] <Lunar_Lander> yea
[21:03] <eroomde> that's why we're CU Spaceflight rather than CU Near-space flight :)
[21:03] <Laurenceb_> heh
[21:03] <Upu> lol
[21:03] <Laurenceb_> are you still going with fin stabilised?
[21:03] <NigeyS> eroomde, using how much propellant? .. for 100km
[21:03] <Upu> what is the propellant system and burn time on that ?
[21:03] <eroomde> at our scale of rocket, it's *all* drag that takes energy
[21:03] <eroomde> not gravity
[21:03] <Upu> solid or liquid ?
[21:03] <eroomde> solid
[21:04] <Laurenceb_> are you still going with fin stabilised?
[21:04] <eroomde> yes
[21:04] <Laurenceb_> interesting
[21:04] <eroomde> Upu: about 4kg total rocket mass, most of which is fuel
[21:04] <Laurenceb_> but the mortar launch gets you up to speed?
[21:04] <eroomde> no mortar launch
[21:04] <Upu> how do you control the attitude ? Fins or vectoring ?
[21:04] <Laurenceb_> aha
[21:04] <eroomde> you need a reaction
[21:04] <eroomde> Upu: passive
[21:05] <Upu> how do you mean ?
[21:05] <eroomde> sorry yes, passive fins
[21:05] <Upu> ah ok
[21:05] <Upu> that is epic
[21:05] <Laurenceb_> eroomde: i looked at spin stabilised, it works well at ~30 revs/second, problem is aiming
[21:05] <Upu> Well good luck , if you need some gaffer tape I have loads of pink stuff left
[21:05] <Upu> :)
[21:05] <eroomde> our carbon fibre rocket we have now would almost do it
[21:05] <eroomde> just fins are to small and mass ratio isn't quite good enough
[21:06] <eroomde> Laurenceb_: yes it helps
[21:06] <Laurenceb_> unfortunately the angular momentum of the spinning rocket isnt really enough to stabilise the platform
[21:06] <eroomde> actually 5hz would be fine for us
[21:06] <Laurenceb_> but if you just want to go up...
[21:06] <eroomde> yes
[21:06] <eroomde> that'll do!
[21:07] <Laurenceb_> i was looking at +-2degrees for orbital and it was getting about +-15degrees owbble in the simulation
[21:07] <Laurenceb_> but yes orbital is a bit mental XD
[21:07] <Lunar_Lander> xD
[21:07] <Laurenceb_> i got an off the shelf HPR motor to go to 100km in the sim
[21:08] <eroomde> it's really not too bad
[21:08] <Laurenceb_> - just; basically a motor casing with nosecone on the front
[21:08] <eroomde> we can do the extra 70km on an L motor without too much trouble
[21:08] <eroomde> according to the sim anyway
[21:08] <Laurenceb_> if you want anything more you need to think about better casings, the mass fraction is terrible
[21:08] <Laurenceb_> <50%
[21:09] <Laurenceb_> eroomde: you know the n-prize has been extended for a year
[21:09] <Laurenceb_> *nprize flamewar begins*
[21:09] <eroomde> yup
[21:09] <eroomde> but it's impossible
[21:09] <Laurenceb_> XD
[21:10] <Lunar_Lander> do you know Van Allen?
[21:10] <Laurenceb_> technically no, realistically if say CUSF had a go, possibly
[21:10] <eroomde> not personally
[21:10] <Lunar_Lander> he once had a Rockoon project
[21:10] <Laurenceb_> with the existing bunch of prats, no chance in hell
[21:10] <Lunar_Lander> he fired two of them to 6000 km
[21:10] <eroomde> yes i've read about his rockooning
[21:11] <eroomde> if you have any pdf's hidden away i'd love to read them!

[21:11] <eroomde> i'm not sure why he bothered with a rockoon though really
[21:11] <Laurenceb_> what?!
[21:11] <Laurenceb_> 6000km.. seriously
[21:11] <eroomde> if you have enough kinetic energy to get to 600km, starting from 30 doesnt't provide a particular boost
[21:11] <eroomde> 6000*
[21:11] <eroomde> Laurenceb_: they were big
[21:12] <eroomde> huge balloons launched from very large ships
[21:12] <Laurenceb_> i see
[21:12] <Laurenceb_> oh van allen
[21:12] <eroomde> the famous rock guitarist
[21:12] <Laurenceb_> yeah ive heard about that - thought this was an amateur project

[21:16] <Laurenceb_> nice retro kit and an actual video of ignition
[21:16] <Laurenceb_> what more could you want :P
[21:17] <Lunar_Lander> ;)
[21:17] <Lunar_Lander> 4000 miles
[21:17] <Lunar_Lander> the rocket was a four stager
[21:17] <Laurenceb_> have you read some of the old material on explorer1 ?
[21:17] <Lunar_Lander> well
[21:18] <Lunar_Lander> I know about the Juno I rocket
[21:18] <Lunar_Lander> and the satellite setup
[21:18] <Lunar_Lander> that it was in fact the last stage with instruments
[21:19] <Laurenceb_> thats very interesting - wish there was more info on the apogee finder algorithm
[21:19] <eroomde> bbl
[21:19] <Laurenceb_> my n-prize design was basically juno1 with s/first stage/balloon

[21:19] <Lunar_Lander> btw
[21:20] <Laurenceb_> its a very interesting project from the point of view of minimum complexity spacelaunch
[21:20] <Lunar_Lander> von Braun had a Juno I with a dummy fourth stage flying in early 1957
[21:20] <Lunar_Lander> he was strictly forbidden to use a live 4th stage
[21:20] <Lunar_Lander> had he'd been allowed, the USA would have had their first satellite
[21:22] <daveake> Tomorrow is 49 years since Telstar launched. I'll remember that when I have my own launch :)
[21:22] <Lunar_Lander> oh btw
[21:22] <Lunar_Lander> "A secondary goal of Farside was to test concepts for a larger five-stage follow-on vehicle, which was to reach the vicinity of the moon. However, this project never materialized."
[21:22] <Lunar_Lander> that is funny
[21:23] <Lunar_Lander> one stage more wouldn't get you to 380,000 km for sure
[21:23] <Laurenceb_> i dont know
[21:25] <Laurenceb_> these things arent linear
[21:26] <Lunar_Lander> http://rocketry.wordpress.com/2009/09/21/haas-rockoon-to-the-moon/

[21:30] <Upu> that looks llike some sort of freaky sex toy
[21:30] <Laurenceb_> more people who need to be sectioned
[21:30] <fsphil> at least it rhymes
[21:30] <fsphil> lol Upu
[21:31] <Lunar_Lander> Xd
[21:31] <fsphil> You do have to wonder about some people
[21:33] <Lunar_Lander> well
[21:33] <Laurenceb_> hmm the multiple developers problem : adding a barometer to openpilot makes the kalman filter unstable as it gets conflicting altitudes
[21:33] <Lunar_Lander> they appearently made Romania's first ZP balloon
[21:33] <Laurenceb_> so instead of correcting the errors in each input, the person adding the baro added fudge factors to make baor track gps
[21:34] <Laurenceb_> as the filter 'wasnt their territory' :S
[21:34] <Lunar_Lander> ah!
[21:34] <Lunar_Lander> no ZP

[22:30] <Upu> thats nice
[22:30] <Upu> not too far
[22:30] <daveake> Not my fault at all LOL
[22:30] <Upu> what sized balloon is it ?
[22:30] <daveake> 1kg
[22:31] <Upu> nice right I'll be listening
[22:32] <daveake> Payload I calculated at 900g but that was with a mobile phone (now removed) and without a tracker. So in theory it'll be a bit less than 900g but I wouldn't be surprised if it's a bit over. Anyway I've assumed it'd end up 1kg
[22:32] <Upu> I like eroomde's diet cam
[22:33] <Upu> might try that sometime :)
[22:33] <daveake> My video cam has a small acceptable voltage range, and refuses to run on Lithiums!
[22:33] <Upu> I use this AEE MD something
[22:33] <daveake> So I added a schottky diode to drop it down a bit
[22:34] <Upu> plugged some lithiums into the USB port on the bottom
[22:34] <Upu> its internal battery runs for an hour
[22:37] <Lunar_Lander> yeah
[22:37] <Lunar_Lander> what about that Schottky diode system you wrote about?
[22:37] <Lunar_Lander> you wanted to short diodes as the voltage was dropping
[22:40] smea (~smealum@85-171-206-227.rev.numericable.fr) joined #highaltitude.
[22:40] <daveake> I didn't bother doing that. They'll last long enough anyway. It would just get a bit more from the batteries. I have put in a manual short and if I get time I'll test the voltage after a few minutes to see if it's dropped enough to be safe to short it.
[22:41] <Lunar_Lander> ah
[22:41] <Lunar_Lander> yeah
[22:41] <daveake> Kodak obviously didn't forsee Lithiums with their higher initial (but not for long) voltage

[23:02] <Lunar_Lander> if I could find someone sponsoring my program
[23:02] <daveake> I had 2 offers!
[23:02] <Lunar_Lander> cool
[23:03] <daveake> This one is a techie company - they do GPS tracking and the timings for the WRC series - so this isn't so removed from what they do (GPS, radio modems, etc.)
[23:03] <Lunar_Lander> yeah
[23:04] <Lunar_Lander> I also wrote to a GPS company
[23:04] <Lunar_Lander> never even got a replay

[23:04] <Lunar_Lander> yeah
[23:04] <daveake> I'd have thought almost anyway supplying the kind of stuff we use would be interested
[23:04] <Lunar_Lander> another company at least wrote back a real letter
[23:04] <Upu> right good luck tommorrow I'm heading off night all
[23:04] <daveake> g'night!
