[00:02] <scotty> im going to cambrdige churchill on saturday yeah edd moore.
[00:02] <scotty> whats a badger board?
[00:02] <jonsowman> badgercub is a small flight computer and radio transmitter with gps etc
[00:02] <scotty> any other trackimg help would be awesome
[00:02] <scotty> oh cool
[00:02] <jonsowman> http://www.srcf.ucam.org/~cuspaceflight/wiki/doku.php?id=badgercub
[00:03] <juxta> if you had something like a badger onboard you would have tracking the whole flight
[00:03] <jonsowman> also its small, lightweight, uses hardly any power
[00:03] <juxta> thats how most people do it - building a flight computer with GPS and radio communication to follow the balloon the whole flight
[00:03] <jonsowman> scotty: when are you planning to launch?
[00:05] <scotty> this saturday
[00:05] <scotty> have arranged with edd
[00:05] <jonsowman> ah right
[00:05] <juxta> have a chat to ed again and see if he can help you out with a board
[00:06] <jonsowman> i'll ask him if i see him in the dept tomorrow
[00:06] <jonsowman> oh...
[00:06] <jonsowman> hi edmoore
[00:06] <juxta> yeah he's here somewhere ;p
[00:06] <jonsowman> ah i see
[00:06] <scotty> is he around?
[00:07] <juxta> I dont think so
[00:07] <scotty> i dont either
[00:07] Action: jonsowman slaps zeusbot for being so smug
[00:07] <scotty> tried to contact him on here ealier
[00:07] <jonsowman> you could send an email to the CUSF list
[00:07] <scotty> i have sent him an email
[00:08] <jonsowman> ok
[00:08] <scotty> he says saturdaay is still on
[00:08] <scotty> anyone else from cambridge?
[00:08] <jonsowman> im in cambridge
[00:08] <scotty> and how does the badger board work (i clicked the link) do u use radio frequency?
[00:08] <jonsowman> yep
[00:08] <scotty> ah well i have no yagi radio
[00:08] <jonsowman> we have all the kit here
[00:08] <scotty> i looked at that route lol
[00:09] <scotty> you have the kit in cambridge?
[00:09] <juxta> scotty: the range is large enough for it to be tracked from cambridge
[00:09] <scotty> :)
[00:09] <scotty> oh awesome
[00:09] <jonsowman> yup
[00:09] <scotty> well any help on more tracking would be awesome...
[00:09] <juxta> then you get live tracking too ;)
[00:09] Jasperw (~jasperw@skeleton2.london.iofc.org) joined #highaltitude.
[00:09] <jonsowman> there are quite a few people around who'll track it if it's got RF onboard
[00:09] <scotty> yeah..any help on that would be cool
[00:09] <juxta> yeah, you could easily have 10 people tuning their radios in scotty
[00:10] <jonsowman> then you're pretty much guaranteed to know where it is wherever it goes
[00:10] <scotty> well thats sounds fantastic...as i am only using the sms tracking..
[00:10] <jonsowman> i'll send an email to the CUSF list
[00:10] <scotty> should i just mention the board to edd on saturday then
[00:10] <scotty> ?
[00:10] <jonsowman> it'll get read quicker
[00:10] <scotty> oh cool
[00:10] <jonsowman> better try and sort it out now if we can
[00:10] <scotty> yeah
[00:11] <jonsowman> what are the launch details?
[00:11] <jonsowman> saturday... churchill college?
[00:11] <scotty> well i have spent 8 months on this project...and the gps module (which i may just replace with the backup tbh...)
[00:11] <scotty> yeah
[00:11] <juxta> scotty: are you at CU also?
[00:11] <scotty> have you got an email
[00:11] <scotty> i will copy u what edd said to me
[00:12] <scotty> i am at kent university
[00:12] <jonsowman> i'm js843@cam.ac.uk
[00:13] <jonsowman> yep if you could forward me that email that'd be great
[00:13] <jonsowman> thanks!
[00:14] <scotty> sent, can u tell me if u have got them thanks :)
[00:14] <jonsowman> yep got them both, cheers
[00:14] <scotty> i am a third year CSE student at kent (my final year)
[00:14] <jonsowman> will email the list now.
[00:14] <scotty> this is my final year project too :)
[00:14] <juxta> nice :)
[00:15] <scotty> I have the payload done, camera everything and gps...just the retriveal i am hesatent about.
[00:15] <juxta> best not lose it then! ;)
[00:15] <scotty> Yeah! so any extra help for retrivel would be good
[00:15] <jonsowman> having a radio live tracking device will be very useful
[00:15] <scotty> then i could put the high res pics on the UKHAS project online
[00:15] <jonsowman> also it means the landing prediction can be updated during the flight
[00:15] <juxta> how are you triggering the camera btw scotty?
[00:16] <scotty> i have a picaxe servo driver, triggering an external remote, that trigers the camera's remote, when the camera tilts it takes a picture.
[00:16] <scotty> its tested to -63 C
[00:16] <scotty> all is well :)
[00:16] <scotty> i have pics i showed ur collegues
[00:16] <scotty> not sure if u saw them or not
[00:16] <scotty> rocket boy did
[00:17] <juxta> ah cool, I was just curious, not a camera I'd seen before
[00:17] <scotty> But yeah camera is fine :)
[00:17] <juxta> I'm not at CU btw ;)
[00:17] <scotty> yeah its a stroke of luck everything
[00:17] <scotty> lots of hard work!
[00:17] <juxta> yeah, it's a steep learning curve
[00:17] <scotty> what uni you at then, or u past?
[00:17] <scotty> uni
[00:17] <juxta> i'm in Australia
[00:17] <scotty> oh cool
[00:18] <juxta> www.adelaide.edu.au
[00:18] <scotty> adelaide my bro went to a uni like that lol
[00:18] <jonsowman> OK sent an email to the CUSF list
[00:18] <Randomskk> saturday launch eh
[00:18] <jonsowman> either Ed or I will email you back
[00:18] <scotty> ok cool. yeah
[00:18] <jonsowman> Randomskk: you up for tracking on sat?
[00:19] <Randomskk> yea definitely
[00:19] <scotty> oh cool, edd seems very busy at the mo..so if u hear word could u send me an email thanks
[00:19] <Randomskk> there's something else on saturday isn't there?
[00:19] <jonsowman> EARS
[00:19] <Randomskk> or I might be thinking of scotty's project actually
[00:19] <Randomskk> ah and that
[00:19] <jonsowman> scotty: will do
[00:19] <scotty> my project is all ready..assuming my parachute comes tommorw morning!
[00:19] <scotty> (been 3 days)
[00:19] <Randomskk> scotty: tracking balloons makes you look cool
[00:19] <scotty> but yeah the badger board sounds cool
[00:20] <Randomskk> jonsowman would probably object to me showing you an example though :P
[00:20] <scotty> well my garmin nuvi can track the long and lat coordinates successfully from mu gps unit!
[00:20] <jonsowman> Randomskk: yes I would.
[00:20] <Randomskk> haha
[00:20] <scotty> and the gps unit can send the coordinates every 5 mins or 1 min if i want it too
[00:20] <jonsowman> having backup systems never hurts
[00:21] <scotty> yeah i would love some lie tracking help
[00:21] <jonsowman> and relying on SMS above 2-3km might prove inadequate
[00:21] <Randomskk> scotty: http://www.srcf.ucam.org/~cuspaceflight/wiki/doku.php?id=badgercub
[00:21] <scotty> i dont want to loose my payload..its my final project after all
[00:21] <scotty> yeah i saw the badger club
[00:21] <jonsowman> yup of course
[00:21] <jonsowman> also this way, we get to track it, which is kinda fun too :)
[00:21] <scotty> but i haven't got the board
[00:21] <scotty> yea
[00:22] <jonsowman> i'm sure we can hunt down a badgercub in the lab somewhere
[00:22] <Randomskk> well you say that
[00:22] <jonsowman> hmm true
[00:22] <Randomskk> there is probably a box full of them
[00:22] <Randomskk> finding it, on the other hand...
[00:22] <jonsowman> lol
[00:22] <jonsowman> edmoore will know
[00:22] <jonsowman> unfortunately he's not here...
[00:22] <scotty> well its this saturday..
[00:23] <scotty> ed does answer his emails, his phone was hay wire recently lol
[00:23] <jonsowman> the boards are ready and made and simply needs attaching to the payload
[00:23] <jonsowman> nothing else needs doing really
[00:24] <Randomskk> power supply and antenna are th emain things
[00:24] <Randomskk> also bc's dodgy gps
[00:24] <jonsowman> hmm i wondered about that
[00:24] <jonsowman> it was fine on Nova 14
[00:24] <jonsowman> not sure what happened on 17
[00:24] <scotty> oh cool
[00:24] <Randomskk> the gps antenna was shit, I hear?
[00:24] <jonsowman> ah right
[00:25] <scotty> i have a gps antenna
[00:25] <jonsowman> i daresay that particular issue has been fixed
[00:25] <scotty> if i can use this badger board, what do i have to do on saturday..i.e do i need to bring anything extra
[00:26] <jonsowman> nothing at all
[00:26] <jonsowman> the board just needs attaching to the payload along with its antenna and power supply
[00:26] <scotty> i am more then happy for poeple to help me track it...i am grateful to :)
[00:26] <jonsowman> CUSF and people generally have the required tracking kit
[00:26] <scotty> So the antenna and powersupply, is in CUSE
[00:26] <jonsowman> yep
[00:27] <scotty> so its just another small piece of kit to put into my payload
[00:27] <jonsowman> exactly
[00:28] <scotty> cool..im just wonderding though..im tracking it by long, lat, in my car via my garmin. How would u guys for exmaple or the trackers tell me where it is..or do i wait till it lands or what? or do i get texts from the trackers..
[00:28] <scotty> how does it work..
[00:28] <scotty> lol sorry i am new to this but tried my best
[00:28] <jonsowman> the people tracking will know where it is, and all of their information gets updated to a central server
[00:28] <Randomskk> basically http://spacenear.us/tracker
[00:29] <jonsowman> either you have internet access in your car and keep an eye on that page Randomskk just linked to
[00:29] <scotty> ah ok, ill have internet in my car due to a dongle 02
[00:29] <scotty> lo
[00:29] <Randomskk> the radio transmits its GPS position via radio which we receive, decode on a computer which extracts the position
[00:29] <Randomskk> it gets uploaded to a server
[00:29] <scotty> nice! i like
[00:29] <jonsowman> cool
[00:29] <Randomskk> the server uses it to draw the balloon's path, as well as calculate the radio horizon, and plot altitude over time
[00:29] <jonsowman> so yeh, just keep that page open in your car :)
[00:29] <Randomskk> plus you can see where all the receiving stations are and which packets each received
[00:29] <jonsowman> all the data gets fed straight to you
[00:29] <scotty> nice, it does the uk then
[00:29] borism (~boris@213-35-235-6-dsl.end.estpak.ee) left irc: Remote host closed the connection
[00:29] <scotty> yeah
[00:29] <Randomskk> it's mostly uk
[00:30] <scotty> well it would be intresting to see how well my gps works and how well the badger works
[00:30] <Randomskk> just happens to be centered on the US as wb8elk did a launch most recently
[00:30] <scotty> oh ok
[00:30] <scotty> but it will work in the uk then
[00:30] <Randomskk> yea
[00:30] <scotty> ?
[00:30] <jonsowman> it will
[00:30] <scotty> kk
[00:30] DoYouKnow (~Michael@adsl-75-4-147-33.dsl.emhril.sbcglobal.net) joined #highaltitude.
[00:30] <Randomskk> http://ukhas.org.uk/guides:tracking_guide has some info on how it works
[00:30] <scotty> so i emailed edd, asking about the badgercub
[00:31] <scotty> i have read that guide lol about 6 months ago
[00:31] <jonsowman> ok, I sent the CUSF list an email anyway
[00:31] <scotty> :)
[00:31] <scotty> i have done alot of reaserch!
[00:31] <scotty> lol
[00:31] <jonsowman> :)
[00:31] <scotty> cool :)
[00:31] <jonsowman> Randomskk: we could leave the radio set up and go see the launch maybe
[00:31] <Randomskk> yea, was thinking that
[00:31] <Randomskk> remote control of the radio is working nicely
[00:31] <jonsowman> yup
[00:32] <Randomskk> and anywhere with wifi will be sufficient to manage it all
[00:32] <Randomskk> or my phone's 3g
[00:32] <Randomskk> though VNC over HSDPA will be painful
[00:32] <jonsowman> yeh
[00:32] <Randomskk> however still perfectly doable, could probably disable second screen for the duration as well
[00:32] <jonsowman> we can get back here from chu quite quickly though
[00:32] <Randomskk> or start a new X session that's just VNC in a smaller window
[00:32] <Randomskk> true
[00:32] <Randomskk> well it's like a 15 to 20min walk? or more like 10?
[00:32] <Randomskk> can't remember
[00:32] <Randomskk> it's all the way up grange rd
[00:32] <scotty> walk? lol
[00:33] <jonsowman> from our college to churchill
[00:33] <scotty> i hope the predictor is good for saturday
[00:33] <scotty> :)
[00:33] <scotty> oh cool
[00:34] <scotty> ed mentioned 12:00 in the predictor, i have yet to get a reply what time he wants me there.
[00:34] <scotty> i am guessing 12:00 though
[00:34] <Randomskk> it is tempting, would be fun to try and go watch
[00:34] <scotty> my payload is all aluminumed up
[00:34] <juxta> Randomskk: just take a small radio?
[00:34] <scotty> apart from the toop due to metal and gps
[00:34] <scotty> top*
[00:35] <juxta> hey scotty, did you have photos up somewhere?
[00:35] <scotty> yeah, i took them down i can put them up again.
[00:35] <Randomskk> juxta: my radio isn't very small
[00:35] <Randomskk> well
[00:35] <Randomskk> it's still 'mobile'
[00:35] <Randomskk> and I've rigged it to run off some lipos which get a few hours each
[00:35] <Randomskk> but big enough to be a bit of a hassle, esp. including an antenna
[00:35] <Randomskk> my computer can control the radio though, frequency etc, through fldigi
[00:36] <Randomskk> and I can vnc to my computer
[00:36] <scotty> what pics would you guys like to see of my payload?
[00:36] <jonsowman> scotty: http://hexoc.ath.cx/alpha/p1.png
[00:36] <Lunar_Lander> good night!
[00:36] <juxta> scotty: yeah that'd be cool :)
[00:36] <scotty> i have dual screen too :)
[00:37] Lunar_Lander (~lunar_lan@p54887BA5.dip.t-dialin.net) left irc: Quit: Lunar_Lander
[00:37] <scotty> kk i will put up
[00:37] <scotty> now
[00:37] <juxta> jonsowman: blistering upstream right there ;p
[00:37] <Randomskk> juxta: I think we're all raping it at once
[00:37] <scotty> uploading pics now
[00:37] <Randomskk> jonsowman: btw it looks like we will actually be doing boolean algebra tomorrow p.m.
[00:38] <jonsowman> sorry guys
[00:38] <scotty> http://imgur.com/JyROl.png
[00:38] <jonsowman> Randomskk: oh :(
[00:38] <scotty> -49.3 C
[00:38] <Randomskk> jonsowman: but it's really a pretty small part of the notes
[00:38] <Randomskk> the rest of the lecture looks shit
[00:38] <jonsowman> hmm
[00:38] <Randomskk> I'm thinking video, or possibly just the completed notes
[00:38] <juxta> nice work scotty
[00:39] <juxta> looks like a good test :D
[00:39] <Randomskk> haha awesome
[00:39] <scotty> http://imgur.com/M36jZ.png
[00:39] <jonsowman> http://www.srcf.ucam.org/~js843/p1.png
[00:39] <scotty> -57.2 C
[00:39] <jonsowman> there we go
[00:39] <scotty> and i'll get my payload pic
[00:40] <jonsowman> interesting, heading direct sout
[00:40] <jonsowman> h
[00:40] <scotty> http://imgur.com/8gItH.jpg
[00:40] <jonsowman> apogee over east london airport roughly? :p
[00:40] <scotty> thats my front of my payload
[00:41] <scotty> i live in kent so maidstone is good for me lol
[00:41] <jonsowman> nice
[00:41] <jonsowman> 3m/s ascent rate puts it landing very near the coast..
[00:41] <scotty> if you want to see any more pics i can upload
[00:41] <juxta> more pics :D
[00:42] <scotty> put the bager tracking (which sounds like a dream for helping me track) how much in reality can it happen for saturday?
[00:42] <juxta> how do you mean scotty?
[00:43] <Randomskk> seems like a fairly reasonable path
[00:43] <scotty> as come saturday when i am at churchill, can edd help me put this badgercub board in my payload and get it running
[00:43] <Randomskk> there are plenty of listeners roughly south
[00:43] <scotty> so we can track with http://spacenear.us/tracker/
[00:43] <Randomskk> if I was at home I'd be better positioned but there you go :P
[00:43] <jonsowman> there will be people at the launch site to get badgercub running
[00:43] <Randomskk> possibly us :o
[00:44] <scotty> cool :)
[00:44] <jonsowman> indeed
[00:44] <jonsowman> dont see why we couldn't go to the launch
[00:44] <jonsowman> i cant see any particular objections to sticking badgercub on it
[00:44] <scotty> any help is appreciated.. 9 months work i put into this..so hopefully 8.2 mega pixel, earth cicumfernce pics :P
[00:44] <jonsowman> dont think ed will mind
[00:45] <scotty> http://imgur.com/YoEga.jpg
[00:45] <jonsowman> yep we know how much goes into these things! spent 8 odd months with mine and lost it sadly
[00:45] <scotty> this pic is the pic with the camera taking a pic through the payload window
[00:45] <jonsowman> but there you go, version 2 is on its way...
[00:45] <scotty> its really clear pic :)
[00:45] <scotty> i was very happy with it
[00:46] <scotty> sorry you lost your payload
[00:46] <scotty> :(
[00:46] <juxta> time for me to make my payload box for mondays launch :)
[00:46] <jonsowman> ah well, these things happen
[00:46] <juxta> jonsowman: which was yours?
[00:46] <jonsowman> just hope we dont lose the next one
[00:46] <jonsowman> Apex I
[00:46] <juxta> ah right
[00:46] <juxta> any ideas as to what went wrong?
[00:46] <jonsowman> http://ukhas.org.uk/projects:apex-i
[00:47] <jonsowman> we lost GPS lock and then radio contact, by the time we got it back it was far too far away and decending
[00:47] <jonsowman> we lost radio contact again due to height, and never found it
[00:47] <scotty> oh no
[00:47] <juxta> bummer :(
[00:47] <scotty> did u put your contact stuff on it|?
[00:47] <juxta> what were you using for radio?
[00:47] <jonsowman> we did
[00:47] <scotty> ah
[00:47] <scotty> well maybe its in a tree
[00:48] <jonsowman> predictions run at the time from the last known positions showed a landing site somewhere just south of Lincoln
[00:48] <jonsowman> but yes, it may well be in a tree lol
[00:48] <jonsowman> anyway Apex II is in the works :)
[00:48] <edmoore> oh sugar
[00:48] <edmoore> ok
[00:48] <edmoore> scotty: http://www.srcf.ucam.org/~js843/p1.png
[00:48] <jonsowman> haha hello edmoore
[00:48] <edmoore> hang on, who did I send the prediction to
[00:49] <edmoore> scotty, did I email you with a prediction for saturday?
[00:49] <juxta> hey ed
[00:49] <jonsowman> edmoore: scotty forwarded me that email
[00:49] <edmoore> ok cool
[00:49] <edmoore> so the forecast is currently really no good
[00:49] <edmoore> we can't overfly central london and come down next to gatwick
[00:50] Xenion (~robert@p57972585.dip.t-dialin.net) left irc: Ping timeout: 265 seconds
[00:50] <scotty> south of lincoln
[00:50] <scotty> thats a long way
[00:50] <scotty> Apex II is cool
[00:51] <edmoore> jonsowman: check email
[00:51] <edmoore> the only cub is currently tied up
[00:51] <jonsowman> edmoore: ah right, shame
[00:51] <scotty> 5th march is friday not sat
[00:51] <scotty> lol
[00:51] <edmoore> right, i have 4 lectures tomorrow so i'm going to head off. scotty - will try a forecast again tomorrow but right now it doesn't look hopeful
[00:52] <scotty> oh cool ok ed :)
[00:52] <scotty> shame the cub is tied up..
[00:52] <scotty> no way around it?
[00:53] <Randomskk> could probably whip up some kind of alternative
[00:53] <edmoore> can't risk loosing it I'm afraid. It's mission critical for a forthcoming experiment for us.
[00:53] <Randomskk> but it would not exactly be tested :P
[00:53] <edmoore> and it's integrated in said experiment right now
[00:53] <Randomskk> edmoore: we still have everything needed for several arduino based basic trackers lying around though
[00:53] <jonsowman> what is said experiment edmoore ?
[00:53] <scotty> ah i see..and there are no spairs?
[00:53] <scotty> spares* or could i make one?
[00:53] <edmoore> they're in the north sea
[00:53] <scotty> lol
[00:53] <scotty> just sounded like a good idea
[00:54] <edmoore> yeah. we should have some more really, but we don't. these were just the prototypes
[00:54] <Randomskk> need to finalise bc2, get some made up
[00:54] <scotty> so u only have one prototype :(
[00:54] <edmoore> Randomskk: you're welcome to knock something up
[00:54] <Randomskk> edmoore: may have a play. there are ntx2s and gpss lying around, right?
[00:54] <scotty> anything to help, and track..would be awesome come saturday
[00:54] <edmoore> yes. we had 4 prototypes, now we're down to one
[00:55] <scotty> ouch
[00:55] <scotty> guess the other 3 brokee
[00:55] <juxta> broke = lost in the sea I suspect
[00:55] <edmoore> 1 in the north sea, one burned out when shorted in action, the other busted during soldering
[00:56] <scotty> ah
[00:56] <edmoore> just to re-iterate. Right now saturday is off unless it shifts away from flying over central london. that's just not something we do
[00:57] <scotty> well edd if the predictions are really bad on saturday u will let me know right? (sent my number in the email). just dont want to make an empty trip.
[00:57] <scotty> oh ok
[00:57] <scotty> cool
[00:57] <edmoore> yep of course. we'll make a call tomorrow
[00:57] <scotty> (just read that)
[00:57] <scotty> i have looked at sunday,its landing in oxford
[00:57] <scotty> and looks good, avoids london
[00:57] <edmoore> oxford is fine :)
[00:57] <scotty> and heathrow
[00:58] <jonsowman> we can deal with oxford
[00:58] <jonsowman> gatwick, not so great
[00:58] <scotty> sunday on the predictor looks good is all
[00:58] <edmoore> however, iain and I might be at EARS on sunday. jonsnowman and randomssk can help you out though :)
[00:58] <scotty> well sunday predictor for 12:00 is looking great...so if we can't so sat can we do sunday
[00:58] <jonsowman> yeh we'll be around sunday
[00:58] <scotty> ok cool...
[00:58] <scotty> well as sat is off now can we say sunday?
[00:59] <scotty> (unless it changes obviously)
[00:59] <scotty> weather wise..
[00:59] <edmoore> i'd hold off that call untill about midday tomorrow
[00:59] <edmoore> it can still shift
[00:59] <scotty> ok...
[00:59] <edmoore> we'll wait for the 0600 UTC forecast to come though (it comes through at about 11)
[01:00] <jonsowman> sounds good
[01:00] <scotty> sounds good to me...if it still is bad and sunday is good, can i get jonsnowman and randomssk emails, if they are helping me on sunday..
[01:00] <scotty> ?
[01:00] <scotty> obviously we'll wait for the final call.
[01:00] <jonsowman> wait for forecast before we sort anything out
[01:00] <edmoore> i'll forward them unless they haven't done it themselves already
[01:00] <edmoore> early sunday morn doesn't look too bad
[01:00] <scotty> cool :) much appreciated.
[01:01] <edmoore> near where I used to work
[01:01] <edmoore> right, night all

[01:01] <jonsowman> see you
[01:01] <scotty> night..
[01:01] <Randomskk> scotty: I can probably make something up with parts we have on hand, but no promises, depends on how much time I can find
[01:01] <jonsowman> might be possible to knock up a tracker before the launch
[01:02] Action: Randomskk is ag611@cam.ac.uk
[01:02] Action: jonsowman is js843@cam.ac.uk
[01:02] <scotty> awesome..well if we have to do sunday thats more time..
[01:02] <Randomskk> we have radios, GPSes, microcontrollers
[01:02] <Randomskk> connecting the three is the trick :P
[01:02] <scotty> i have time tommorw in the lab but looking at the board online its not something i can make in a day lol
[01:02] <jonsowman> yup
[01:02] <scotty> can't make in a day*
[01:03] <scotty> lol
[01:03] <scotty> cool, so is there anything you guys need from me..before sat/sun. apart from the obvious.
[01:04] <Randomskk> don't think so, uh
[01:04] <Randomskk> so long as there's some way of connecting this thing up to power
[01:04] <Randomskk> and some way of connecting an antenna to the outside
[01:04] <scotty> thing?
[01:04] <Randomskk> radio+gps+micro hybrid
[01:04] <scotty> it has an antenna..and powered by lithium inion
[01:05] <Randomskk> what kinda antenna though?
[01:05] <scotty> oh well i have an antenna..
[01:05] <DoYouKnow> lithium ion and not lithium?
[01:05] <DoYouKnow> lithium withstands cold temps, lithium ion does not afaik
[01:06] <scotty> was using it but thinking i wont...its a quad band cellual antenna SMA
[01:06] <scotty> lithium ion yeah sorry
[01:06] <Randomskk> might be worth it for the cell phone, but won't do the radio any good really
[01:06] <Randomskk> anyway I'll have a think about it, may be able to come up with something that'd be better than nothing
[01:06] <scotty> humm.
[01:06] <Randomskk> bed time now, speak to you later
[01:07] <jonsowman> yup i'm off too
[01:07] <scotty> night dudes, appreciate all the help!
[01:07] <Randomskk> np
[01:07] <jonsowman> we'll see how the weather looks tomorrow
[01:07] <scotty> look forward to the weather forcasts!
[01:07] <scotty> yeah
[01:07] <scotty> :)
[01:07] <jonsowman> night all
[01:07] <scotty> i really want to do this flight after 9 months wait lol

[13:21] <mc-> I've asked Seeed to DHL it

[13:22] <mc-> pcbtrain is alot more than Seeed
[13:22] <MikeMc68_> really?

[13:23] <juxta> seeedstudio are very cheap
[13:23] <juxta> I'll try them for my next board
[13:23] <MikeMc68_> i can never understand how getting parts done in anotehr country - plus shipping from overseas - can be cheaper than getting it done locally
[13:23] <mc-> bbl
[13:23] <MikeMc68_> Shipping from Seeed for anything purchased on their store is very slow
[13:23] <juxta> I suspect seeed do similar to batchpcb

[13:24] <juxta> and batch their orders to a large manufacturer

[14:23] <edmoore> jonsowman: ground plane monopole
[14:24] <edmoore> so one 17.5cm active element and 4 grounded radials
[14:24] <edmoore> or, you could try a bazooka dipole as they're fun too
[14:24] <edmoore> and may integrate better with the fact that scotty hasn't designed this with an antenna in mind
[14:25] <jonsowman> right ok
[14:25] <jonsowman> the ferret board isnt working at all atm
[14:25] <jonsowman> the gps gets lock but the values in the radio transmitted string are rubbish

[14:29] <jonsowman> mm yeh might come in handy
[14:29] <edmoore> should run off a modern mag-safe charger, i think.
[14:30] <edmoore> actually don't quote me on that, i don't know
[14:30] <jonsowman> it will

[15:50] <SpeedEvil> strtok seems likely to be very large
[15:50] <SpeedEvil> I would simply DIY.
[15:50] <Randomskk> yea
[15:50] <Randomskk> I have used strtok to parse NMEA in the past, but that was on a UMPC running XP
[15:51] <Randomskk> and even that was messy and yuck
[15:51] <Randomskk> any good ideas? considering a character-by-character state machine
[15:52] <SpeedEvil> Is current char a ,. If it is, do something to the temporary string based on a case statement. If it is not, then append the current char to a string.
[15:52] <Randomskk> sounds like a slightly larger state machine :P
[15:52] <Randomskk> fair enough
[15:52] <SpeedEvil> it's pretty simple to implement in asm though
[15:52] <Randomskk> the rtty appears to be working well enough
[15:53] <Randomskk> eh, this is on an arduino so probably use the arduino libs or at least avr-libc and gcc-avr for speed of development
[15:53] <SpeedEvil> Or C even.
[15:53] <SpeedEvil> few lines, tops.
[15:53] <Randomskk> yea
[15:56] <Randomskk> sadly it seems all of atmel's avr+rf chips are 868mhz or 2.4ghz, no 434s
[15:59] <Randomskk> this thing will be using an ntx2 though since we have one lying around

[19:24] <jonsowman> sunday is looking better
[19:24] <scotty> I am putting a video camera in my payload as well as a camera now :)
[19:25] <scotty> and i finished my payload, tidying it up now
[19:25] <jonsowman> sounds good
[19:25] <scotty> will put up pictures in a bit.
[19:27] <scotty> So will you jonsowman and your mate be able to help me on sunday..if weather is permitting?
[19:29] <scotty> And also do you guys have access to the helium or only edd? as i need the helium
[19:30] <jonsowman> we need to talk to ed about the helium
[19:30] <jonsowman> but weather permitting Randomskk and I will be around to help with the launch
[19:30] <scotty> yeah, i'll send him a text now..but if someone could ask him
[19:30] <scotty> cos no helium = no flight lol

[20:47] <natrium42> you can access them via the schematic editor or the pcb editor
[20:47] <natrium42> ">VALUE" is just a placeholder that gets populated automatically
[20:47] <natrium42> same with ">NAME"
[20:48] <Laurenceb> or not in my case
[20:48] <Laurenceb> I have to set it on the schematic

[21:36] <jonsowman> anyone done arduino based trackers?
[21:37] <SpeedEvil> yes
[21:37] <natrium42> /o
[21:37] <jonsowman> right so im modifying the TCCR0B register
[21:37] <jonsowman> to make the PWM 64khz
[21:37] <SpeedEvil> I think Randomskk is doing one
[21:37] <jonsowman> yeh me and him are doing the same one
[21:37] <jonsowman> im working on it atm
[21:37] <SpeedEvil> ah
[21:37] <jonsowman> but changing the PWM frequency makes software serial not work
[21:38] <jonsowman> incoming chars are all garbled
[21:38] <MikeMc68> evening
[21:38] <jonsowman> at the moment ive got it putting the PWM freq back to 1khz for the GPS read, then upping it to 64khz for transmit
[21:38] <jonsowman> which is horrible and hacky
[21:38] <jonsowman> any ideas?
[21:38] <MikeMc68> So who is launching Sunday ?
[21:39] <natrium42> scotty
[21:39] <natrium42> weather permitting
[21:39] <MikeMc68> from where?

[21:41] <MikeMc68> ping scotty
[21:42] <natrium42> MikeMc68, you plan on attending the launch?
[21:42] <MikeMc68> i'd like to - depends when on Sunday
[21:42] <MikeMc68> and if he wants me of course
[21:42] <natrium42> cool
[21:43] <MikeMc68> i'd like to video one
[21:43] <jonsowman> early sunday is looking best
[21:43] <jonsowman> 10-11am
[21:43] <MikeMc68> in HD - proper edited video
[21:43] <MikeMc68> hmm
[21:46] <MikeMc68> jonsowman are you part of the launch ?
[21:47] <jonsowman> yeh this is what this arduino tracker is for
[21:47] <MikeMc68> so who is doing the radio tracking ?
[21:47] <Laurenceb> jonsnowman: you would expect software pwm to work?!
[21:47] <Laurenceb> *serial
[21:48] <Laurenceb> any ISR running and your out of luck
[21:48] <natrium42> disable interrupts :D
[21:49] <MikeMc68> yup
[21:49] <jonsowman> will do...
[21:49] <scotty> hey natrium :)
[21:50] <natrium42> hi scotty
[21:52] <scotty> looks like my flight is this sunday now :)
[21:52] <scotty> which is good!
[21:52] <natrium42> :)
[21:52] <MikeMc68> scotty: Need any help on Sunday with anything ?
[21:53] <jonsowman> woo it works
[21:53] <jonsowman> delayMicroseconds() used to disable interrupts in arduino 0.017
[21:53] <jonsowman> but not any more
[21:53] <jonsowman> hence this code used to work, and now doesnt

[21:58] <scotty> I'll gladly excpet any help, its my first timing launching.
[21:58] <MikeMc68> who is doing the radio tracking ?
[21:58] <scotty> and i have a gps, sms communication system, so any other tracking would be great
[21:59] <scotty> not sure if a badgercub baord or something simliar can be made up
[21:59] <jonsowman> we need people to help track
[21:59] <jonsowman> it wont be a cub
[21:59] <MikeMc68> i have a radio and a yagi and a vehicle and a laptop with usb modem :D
[21:59] <scotty> yeah..
[21:59] <scotty> oh awesome :)
[22:00] <scotty> i have usb modem and laptop too, and garmin gps
[22:00] <scotty> using garmin to track via sms\
[22:00] <jonsowman> me and Randomskk will track after the launch
[22:00] <MikeMc68> so is anyone going to track in a vehicle with a radio ?
[22:01] <scotty> oh cool jon..but how can you help track, if there is no cub..reckon we can knock something up?
[22:01] <jonsowman> scotty: i'm working on something at the moment
[22:01] <jonsowman> MikeMc68: not that i know of
[22:01] <MikeMc68> well if you like i can come along with my radio gear
[22:02] <scotty> oh yeah thought i'd mention just finished my 2nd camera setup.it runs for 2.30 hrs..so that means video/ audio and 8.2 megapixel photos from my other camera (around 200 pics)
[22:02] <scotty> thought would be awesome Mike and very appreciated..but im not sure what radio setup everyone can get setup.
[22:03] <scotty> but if we can radio track some way that would be cool:)
[22:03] <MikeMc68> you have a NTX2 on board right ?
[22:03] <jonsowman> provided we can get this tracker running by sunday
[22:03] <jonsowman> but yes this tracker is an NTX2
[22:03] <scotty> nope, was using a gm862 board, but was too buging up
[22:03] <scotty> oh cool
[22:03] <MikeMc68> so then i can co\me along with radio, yagi, whip, laptop, usb modem, etc. and track in a vehicle
[22:03] <scotty> i can send my gps long and lat to 2 other mobiles too :)
[22:04] <scotty> cool cool Mike :)
[22:04] <MikeMc68> and we can use PMR radio's to talk between the vehicles
[22:04] <scotty> if u have a spare, as i dont have a pmr radio.
[22:04] <scotty> lol
[22:05] <MikeMc68> yeah i've got a pair

[22:52] <MikeMc68> i like the landing near Ashford - not far from home :D
[22:52] <Laurenceb> SpeedEvil: yeah, its almost finished
[22:52] <Laurenceb> just needs the proper footprint for the falcom module
[22:52] <Laurenceb> that pin header will be buried underneath it
[22:53] <Laurenceb> its designed to have independant pwm in and out, so it can do "fly by wire"
[22:54] <scotty> ashford is good, near kent where i am lol
[22:54] <SpeedEvil> watchdog or something for unexpected brownouts?
[22:54] <SpeedEvil> or oopses

[23:01] <MikeMc68> VCC seems to split so maybe they are current limiting to a different part of the circuit
[23:03] <jonsowman> right so tracker is working
[23:03] <jonsowman> we can put it on scotty's launch on sunday if it happens
[23:03] <jonsowman> unfortunately this particular GPS will cut out at 24km
[23:04] <jonsowman> but much better than nothing at all
[23:04] <jonsowman> scotty: does your project have a name?
[23:06] <MikeMc68> why will it cut out at 24km ?
[23:07] <scotty> umm haven't thought of a name really...any ideas i am welcome too
[23:07] <MikeMc68> fucknugget
[23:07] <jonsowman> lmao MikeMc68
[23:07] <scotty> oh awesome a tracker dor sunday :)
[23:07] <scotty> for*
[23:07] <jonsowman> this GPS is just altitude limited to 24km
[23:08] <scotty> yeah well after 24km when it comes down wont it come back into range?
[23:08] <Laurenceb> MikeMc68: ublox say never use a resistor or a ferrite like that
[23:08] <Laurenceb> to reduce noise
[23:08] <Laurenceb> so its very odd
[23:08] <MikeMc68> what GPS module are you using ?
[23:08] <Laurenceb> SpeedEvil: cya
[23:08] <Laurenceb> FSA03
[23:08] <jonsowman> scotty: yes it will regain lock under 24km

[23:09] <MikeMc68> that's a bummer
[23:09] <MikeMc68> you won't know what height it gets to
[23:09] <MikeMc68> i even have a Lassen IQ you could borrow
[23:09] <jonsowman> unless the onboard kit records it
[23:09] <MikeMc68> from what though ?
[23:09] <jonsowman> there is another GPS onboard, am i right scotty
[23:09] <jonsowman> ?
[23:10] <scotty> i did have a gm862 one, which i had working, but its tempermental and so i have forgoen it for a better more reliable one (i.e the backup) that should work constantly..
[23:10] <scotty> sending me the long and lat, direction speed etc every 5 mins
[23:10] <Laurenceb> oh its zero ohm resistor
[23:10] <Laurenceb> never mind
[23:11] <Laurenceb> RTFM :P
[23:11] <scotty> and i can work out the hieght to
[23:11] <Laurenceb> they have that board design avaliable on their site
[23:11] <Laurenceb> gtg
[23:11] <jonsowman> if you think of a name, tell me scotty
[23:11] <jonsowman> the radio needs an identifier which is normally the project name
[23:11] <jonsowman> at the moment it's just "FERRET" which is the name of the tracker board

[23:12] <scotty> judges 200 meters a minute
[23:12] <MikeMc68> i have never understood the point of a zero ohm resistor
[23:12] <scotty> a text of gps coordinates every 5 mins should be fine :)
[23:13] <scotty> oh ok
[23:13] <MikeMc68> that will only work below a certain height though
[23:13] <scotty> umm...i'll have a quick think now
[23:13] <scotty> lol
[23:13] <MikeMc68> and presuming you can get lock
[23:13] <scotty> yeah i know, but this gps always locks..
[23:13] <scotty> and is well built.
[23:13] <MikeMc68> i mean GPRS lock
[23:13] <scotty> my personal one was good, but to buggy. and the gps would break at a certain altitude.
[23:14] <scotty> well my best bet is this main gps :) which will work!
[23:14] <scotty> ( i can tell it to text me ever 2 mins if i want to) and if it looses gps signal it will tell me
[23:14] <scotty> and tell me the last known position
[23:15] <scotty> but i get you i will proabbly have to wait 1-2 hours till it comes down..but it will register where it is
[23:15] <scotty> as its in a loop of telling me where it is
[23:15] <scotty> and when its back in reception it will tell me
[23:15] <scotty> if u get me
[23:15] <jonsowman> yup

[23:15] <MikeMc68> what i mean is.......
[23:15] <jonsowman> GSM reception above 2-3km is sketchy at best
[23:15] <scotty> yeah
[23:16] <MikeMc68> sometimes GSM can take a long time to get a signal and lock from altitude
[23:16] <MikeMc68> there are well known cases where the SMS doesn't start working till AFTER the payload has hit the ground
[23:16] <natrium42> scotty, what's the name of your project?
[23:16] <MikeMc68> hence an RF transmitter is almost essential
[23:17] <scotty> i'll call my project Orion.
[23:17] <scotty> unless that name is taken already
