[13:33] <edmoore> hi josh
[13:36] <jatkins> hi
[13:36] <jatkins> just doing some arduino stuff now, with the serial
[13:36] <edmoore> awesome
[13:36] <jatkins> I've got the gps connection done, just I'm struggling with the parser a bit
[13:37] <edmoore> well it is one of the trickiest bits, for sure
[13:37] <jatkins> ok
[13:37] <jatkins> basically, I'm just getting nmea data in
[13:37] <jatkins> so it's (at least) two different data types: integers and chars
[13:38] <edmoore> well it's all sent as chars
[13:38] <jatkins> ok
[13:38] <jatkins> so if I store the result from Serial.read() in a char, I should be ok?
[13:39] <edmoore> so if you see '5' in the terminal, it's not actually sent 5, it's sent 35, which is '5' in ascii
[13:39] <jatkins> ok
[13:39] <jatkins> oh right, I only thought letters had number codes in ascii
[13:39] <edmoore> now off the top of my head i don't know arduino code, however i can find some similar code to show you, if you want
[13:39] <edmoore> let me have a look
[13:39] <jatkins> ok
[13:39] <jatkins> void setup() {
[13:39] <jatkins> Serial.begin(9600); // Initialize the serial connection
[13:39] <jatkins> }
[13:39] <jatkins> void loop() {
[13:39] <jatkins> if(Serial.available()>0) {
[13:39] <jatkins> int nmea = Serial.read();
[13:39] <jatkins> Serial.print(nmea, BYTE);
[13:39] <edmoore> no, everyhting exists in ascii
[13:40] <jatkins> Serial.print(nmea, DEC);
[13:40] <jatkins> Serial.println("");
[13:40] <jatkins> }
[13:40] <jatkins> right, ok
[13:40] <edmoore> 012345etcabcde...ABCDE...£$%&^
[13:40] <edmoore> all of the standard keyboard characters exist in ascii
[13:40] <jatkins> ok
[13:40] <jatkins> http://www.arduino.cc/en/Serial/Print
[13:41] <jatkins> I'm doing Serial.print so I can see the output without going through hypeterminal- the arduino ide has a built in 'serial monitor'
[13:41] <edmoore> cool
[13:41] <edmoore> so that's showing you all the ascii coming in?
[13:41] <jatkins> yeah
[13:42] <jatkins> given the data on the link above, should I do Serial.print(nmea, BYTE) only/
[13:42] <jatkins> ?*
[13:42] <jatkins> (and obviously change int nmea to char nmea)
[13:43] <edmoore> I'm honestly not sure
[13:43] <jatkins> ok, np, I'll just try it out
[13:44] <edmoore> i'll scour the web to see how the arduino functions work
[13:44] <jatkins> thanks
[13:44] <edmoore> yeah, cannot go wrong if you try it out
[13:44] <edmoore> :)
[13:44] <edmoore> which gps have you got?
[13:45] <edmoore> this thread might be useful http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1166042147/
[13:45] <jatkins> I think it's a sirf one
[13:45] <jatkins> mc gave it to me
[13:45] <edmoore> the em-406 is sirf
[13:46] <edmoore> this is better layed otu and will probably help more: http://www.arduino.cc/playground/Tutorials/GPS
[13:46] <jatkins> thanks
[13:47] <jatkins> I should be ok writing the actual parser, I've done web api and regex stuff before, just need to get the ascii really
[13:47] <jatkins> I think I can use substr() and split()
[13:48] <edmoore> ok awesome.

[14:04] <edmoore> yup
[14:04] <edmoore> agree with most of it

[14:06] <jcoxon> haha
[14:06] <jcoxon> i don't want a fight
[14:07] <edmoore> but that's not really for sound engineering reasons, just i'm keen to try out badger
[14:07] <jcoxon> i know
[14:07] <jcoxon> well i'm going to volunteer/assign myself to admin and weather
[14:07] <jcoxon> and perhaps ground software
[14:07] <jcoxon> if thats okay
[14:08] <edmoore> np!
[14:08] <jcoxon> can't be arsed with payloads
[14:08] <jcoxon> haha
[14:08] <jcoxon> do you like my diagram?
[14:09] <edmoore> not seen it?

[14:12] <edmoore> 18kft?
[14:12] <edmoore> oh i see
[14:12] <edmoore> sorry
[14:12] <edmoore> secondary beacon necessary?
[14:13] <edmoore> I think this is high-risk enough to go for broke without the usual backups
[14:13] <edmoore> or rather, high-goal but not high-risk
[14:13] <jcoxon> hmmm, i'm not sure
[14:14] <jcoxon> it would be a shame to have powerfailure yet achieve our goal
[14:14] <jcoxon> i'll weigh my beacon i've made
[14:14] <edmoore> well i guess we shoul see how much a 2nd beacon weighs
[14:14] <edmoore> cool
[14:15] <jcoxon> hehe i wrote a webbrowser in rubycocoa
[14:15] <jcoxon> and a website has actually linked to it
[14:15] <edmoore> lol
[14:15] <jcoxon> its a load of rubbish though quite lightweight
[14:19] <jcoxon> okay, i better be off to the library
[14:19] <jcoxon> sad isn't it, the first day of my holidays and i'm off to do some work
[14:20] <edmoore> yep, tragic
[14:20] <edmoore> c'est la vie

[14:21] <jcoxon> feel free to add to the wiki page
[14:21] <Hiena> Groan...
[14:21] <edmoore> what's up?
[14:24] jcoxon (n=jcoxon@host86-162-222-251.range86-162.btcentralplus.com) left irc: "Leaving"
[14:25] <Hiena> Nah, just the life. I finished my work 20:30 yesterday and wanted go to fly tomorrow. At the morning i wake up late, phoned to my pals about the weather conditions at the hangar. I planned to go there with the 10:30 am train, which was canceled due today is a national holyday. So i choosed the later one, but i forgot it's departure time, and when i checked the schedule i was late. So i was stuck at home...
[14:25] <edmoore> sounds about right
[14:25] <edmoore> :)
[14:26] <Hiena> No. I have damned 50km between me and my glider, and i have no car.
[14:28] <edmoore> build a payload!
[14:29] jatkins (n=jatkins@79-73-64-109.dynamic.dsl.as9105.com) joined #highaltitude.
[14:29] <Hiena> I have to wake up early, i have to catch a train, i have beg to the guys to carry my glider to the hillside, and so, and so on. If the weather is not good at the startplace i wasted a day. Not to mention the sleep deprivation from countinues OT.
[14:30] <Hiena> edmoore, i almost done the horizont detector's code.
[14:30] <edmoore> are you using thermopiles?
[14:31] <Hiena> Nope. It's camera based.
[14:31] <edmoore> oh wow
[14:31] <edmoore> so some fairly serious code?
[14:32] <Hiena> Not so. basically a treshold algorithm on the captured picture red channels and a least square calculation on the points.
[14:34] <edmoore> oh fair enough. still, cunning
[14:34] <edmoore> what resolution?
[14:34] <edmoore> i tried doing a line following robot with a nintendo camera using that method
[14:35] <Hiena> The feed is 320x240 and the number of the average points is depends on the ground unit calculation power.
[14:36] <Hiena> Also depend of the power hungry of the wing twist control algorithm.
[14:38] <edmoore> what's a wing twist control a'rthm?
[14:39] <Hiena> I found, it's running pretty smooth on the 300Mhz machine with 32 control point. Currently thinking on a better filter algorithm because the dowstream is damned noisy at 2.4GHz.
[14:41] <Hiena> Oh, that is the brainchild of the pals from the university. It's a special algorithm an mechanism to control the wing flatter and twist on a superflexible wings.
[14:42] <edmoore> so this is proper research then?
[14:45] <Hiena> Proper? Don't joke. ;) We have ideas, but no budget. The guys teaching at the uni. and doing the research at the remaining time. I'm working for free, because this is thousands times more interesting than holding the soldering iron.
[14:45] <edmoore> lol
[14:46] <Hiena> The telemetry system and the other stuff was bought from my lunch money, which is not bad because i still have 15 kg plus.
[14:47] <Hiena> Also the most thing is was hacked together at the nights and coded at one hours train travels.
[14:48] <edmoore> do you have a website?
[14:50] <Hiena> Nope. Because the guys at the uni. wants to sell the algorithm later, also we have no time to publish it. With some luck, they will debut on some conference at september.
[14:52] <edmoore> cool
[14:52] <Hiena> The deadtime for the article is May. And i want to put together the two sofware and making some flight videos.

[15:31] <edmoore> right now and waiting for the ol' pcb's to arrive!
[15:31] <edmoore> am waiting*
[15:31] <mc-> I'll ask Olimex what's happening
[15:32] <edmoore> i'm not acticely waiting, i think it's all still on course
[15:32] <edmoore> but yeah
[15:32] <mc-> would Mark send us some plastic?
[15:32] <edmoore> he only wanted to sell complete envelopes
[15:32] <edmoore> http://wiki.ukhas.org.uk/projects:atlas
[15:32] <edmoore> want to test the pcbs on this
[15:33] <edmoore> it's a fun and d0-able thing
[15:34] <mc-> just reading the atlas page, jcoxon better get ready for spam
[15:34] <edmoore> he just had to delete 500 messages, aparently
[15:35] <mc-> once it's known there's no going back
[15:36] <mc-> I've ordered components to build some 10MHz transmitters
[15:36] <edmoore> awesome
[15:37] <mc-> how much can a 1.5kg balloon lift?
[15:37] <edmoore> could send something out over the north sea and see what happens
[15:37] <edmoore> depends on alt
[15:37] <edmoore> we're going for 150g
[15:37] <edmoore> plus maybe 100 excess lift
[15:38] <edmoore> maybe more than that actually to compensate for diffusion
[15:38] <mc-> can a latex balloon float? Maybe with a balloon to provide lift that bursts, then floats on 1 balloon?
[15:39] <edmoore> i guess so yeah
[15:39] <edmoore> it should stay at the alt of the previous one on burst
[15:39] <edmoore> but it would have to be exactly right, and diffusion would kill it eventually
[15:39] <mc-> yes
[15:40] <mc-> is it possible to build a ZP balloon using a simple construction? ie no gores?
[15:41] <edmoore> i guess you could. it'd just be a less optimal shape
[15:41] <mc-> weld together a few bin liners?
[15:42] <edmoore> i don't follow
[15:42] <edmoore> you'd surely have to cut them?
[15:43] <mc-> 2 biners welded together?
[15:44] <mc-> it would be good to launch something, let it drift for an hour, and then command it to cutdown.
[15:44] <Hiena> Bin liners for the president!
[15:44] <mc-> of the USA?
[15:45] <edmoore> well it'd be quite small, 2 bin liners welded together
[15:45] <edmoore> couldn't lift much
[15:46] <mc-> doesn't need to, my GPS weight a few grams, plus a Liion batt
[15:46] <edmoore> go for it then
[15:46] <edmoore> (but a few grams could still be a challenge for 2, i think)
[15:47] <Hiena> mc-, 9 bin liners together.
[15:48] <mc-> I saw that. How about 2 balloons with 2 liners each?
[15:48] <Hiena> And one reel wide duct tape.
[15:48] <edmoore> still, if you start doing that, you're not that far off b&q dust sheet welded together. which is how me did our zp
[15:48] <mc-> that took lots of time, didn't it?
[15:49] <edmoore> yep
[15:49] <edmoore> i'd be suprised if a welded bin liner one took that much less
[15:50] <edmoore> it's welding that takes the time
[15:50] <edmoore> not cutting
[15:50] <mc-> you used tape to weld to?
[15:50] <mc-> is that easy to find?
[15:51] <edmoore> we cut down rolls of it
[15:51] <edmoore> to about 1" wide
[15:51] <edmoore> it was samples from a plastics company
[15:51] <mc-> would they give more samples away?
[15:52] <edmoore> probably!
[15:52] <edmoore> we just sked for some
[15:52] <edmoore> no begging or hard-selling
[15:53] <mc-> please email me the contact
[15:53] <edmoore> I'll find it out - I didn't get myself

[19:56] <Hiena> Well, i think the drinking straw is really, really, underestimated as the modell building materrial. Lightweight, strong, and aesy to shape.

[20:33] <Hiena> It's a little bit early, but anybody from the channel will be at the ICAS 2008 and the AIAA Aviation Technology, Integration, and Operations Conference?
[20:36] <Laurenceb> whereabouts?
[20:37] <Hiena> http://www.icas2008.org/
[20:37] <Laurenceb> rocketboy: hi there
[20:37] <Laurenceb> I found out what the problem with the radio was
[20:37] <Laurenceb> the first byte always has the last 4 bits = 1, and then the start bit for the second byte isnt always correct
[20:38] <Laurenceb> theres no problem if the power saving is turned off... I dont understand it
[20:39] <Laurenceb> I suspected hardware damage, so I investigated further by changing the say the buffer was stored, so it used different sram addresses
[20:40] <Laurenceb> but no luck, unfortunately I think i fried the avr by shorting some pins, so I've made up a new board
[20:40] <Laurenceb> and same problem, so its not hardware

[21:03] <Laurenceb> hey jcoxon
[21:05] <jcoxon> hey Laurenceb
[21:05] <jcoxon> how are you?
[21:06] <Laurenceb> not so bad
[21:06] <Laurenceb> been chilling out
[21:06] <jcoxon> excellent
[21:06] <Laurenceb> finally got by braft project report submitted yesterday :P
[21:06] <Laurenceb> braft*
[21:06] <Laurenceb> arggg draft*
[21:06] <jcoxon> good good
[21:07] <Laurenceb> whats wrong with me
[21:07] <Laurenceb> cant tell the difference between b and d for some reason
[21:07] <Laurenceb> I've done some more work on the radio
[21:07] <jcoxon> yeah i read
[21:08] <Laurenceb> very odd, I've asked on #avr but no luck
[21:08] <Laurenceb> still, theres lots of debugging tricks I can do
[21:09] <jcoxon> cool
[21:09] <Laurenceb> I guess one problem is that I dont fully understand whats involved in hybernating an avr
[21:11] <jcoxon> hibernating :-)
[21:13] <Laurenceb> thats what its called well that or sleep mode
[21:15] <jcoxon> i know, i was correcting you spelling
[21:16] <Laurenceb> doh my spelling
[21:16] <jcoxon> haha your*
[21:16] <Laurenceb> lol :P
[21:17] phatmonkey (n=ben@81.2.121.150) joined #highaltitude.
[21:17] <Laurenceb> the odd thing is its similar to problems I've seen before with avr where you can corrupt ram locations
[21:33] <jcoxon> how strange
[21:41] <Hiena> Well, the ringwing is almost ready to be covered. I had a good feelings about this experiment.
[21:41] <Hiena> Anyhow, still i need a digital scale.
[21:50] <rocketboy> I say jcoxon - is there any way you could add a search function to the #highaltitude channel logs - a sort of grep string highaltitude.log.* ?

[21:51] <jcoxon> rocketboy, hmmmmmm
[21:52] <jcoxon> are you looking for keywords?
[21:53] <rocketboy> yep - say someone has been talking about "widgit" then I'd like to know what logs widgit has been mentioned so I can look them up
[21:54] <rocketboy> I know its a lot to admit but I don't read all the logs (shock horror)
[21:54] <jcoxon> haha
[21:54] <jcoxon> okay i'll look into it
[21:54] <rocketboy> it would be really helpful (to me)
[21:54] <Hiena> Is the logs one page/log?

[21:55] <Hiena> rocketboy, do you have midnight commander?
[21:56] <rocketboy> nope
[21:56] <Hiena> Linux based operating system?
[21:57] <rocketboy> nope - not at the mo - although I'm thinking about it
[21:58] <Laurenceb> I really like ubuntu
[21:58] <Laurenceb> but atm I'm using XP, as avr studio only runs on xp
[21:59] <rocketboy> I thought you hated it?
[21:59] <Laurenceb> hated what XP?
[21:59] <Laurenceb> linux is many times better imo :P
[21:59] <rocketboy> I was goint to put ubuntu on my laptop - but then i got used to vista
[22:00] <rocketboy> nope - you said you hated ubuntu the other day
[22:00] <Laurenceb> haha I probably didnt mean it but it can be annoying sometimes
[22:00] <Laurenceb> its not as reliable as XP at the moment
[22:00] <rocketboy> - dam see if I had a log serch i could find out what day that was
[22:01] <rocketboy> search
[22:01] <Laurenceb> hehe
[22:01] <Hiena> Give me the keyword and i'll search for it.

[22:02] <Laurenceb> dont like it?
[22:03] <jcoxon> hehe
[22:03] <jcoxon> I don't mind it
[22:03] <jcoxon> and i've used it for quite a while
[22:03] <jcoxon> i prefer OSX
[22:03] <Laurenceb> I find it nice for doing serious things

[22:04] <jcoxon> it does :-p
[22:05] <jcoxon> you need to make a hackintosh
[22:05] <Hiena> Ehehehe...
[22:05] <Hiena> Okay. Time to sleep.
[22:05] <Laurenceb> really?
[22:05] <Hiena> Good night all!

[22:06] <Laurenceb> probably not the best idea :P
[22:08] <Laurenceb> rocketboy: any ideas on my radio problem?
[22:08] Action: rocketboy sips a rather nice bottle of crin roja 2005
[22:09] <rocketboy> nope - sounds AVRish
[22:09] <Laurenceb> hehe
[22:09] <rocketboy> my solutiuon would be to use a PIC
[22:09] <Laurenceb> :P
[22:09] <Laurenceb> http://pastebin.com/m2cc89089
[22:10] <Laurenceb> works like that, with lines 219-236 commented out
[22:10] <jcoxon> rocketboy, the whole bottle?!?
[22:10] <rocketboy> nope only 1/2 so far
[22:12] <rocketboy> thats the trouble with a bottle of wine - 1) its moreish 2) it sould be drunk shortly after opening
[22:12] <Laurenceb> hehe
[22:12] <Laurenceb> hmm is atomic code a good idea? when changing global volatiles that are used inside interrupt service routines??
[22:13] <rocketboy> yep
[22:13] <Akadecca> for sure
[22:13] <rocketboy> you either need semaphores - or disable interrupts while changing
[22:13] <Laurenceb> ok, I'm using that in my code for send_char
[22:14] <Akadecca> jcoxon: where is the link to your cutdown device?
[22:14] <rocketboy> you can be reasonably sure that a byte set is atomic - but not much elese
[22:14] <rocketboy> s
[22:14] <rocketboy> else
[22:15] <jcoxon> Akadecca, ummm its not mine :-), its on the wiki
[22:15] <Akadecca> just the set though, not the whole read, modify, write unf
[22:16] <jcoxon> http://wiki.ukhas.org.uk/ideas:flight_support#pyrotechnic_cutdown_device
[22:16] <Akadecca> search is broken on the wiki btw
[22:16] <Laurenceb> Akadecca: see the code I paste binned
[22:16] <rocketboy> yep - depends on the processor - but some can interrupt mid instruction
[22:16] <jcoxon> really? it seems to work for me
[22:17] <Akadecca> http://www.pegasushabproject.org.uk/wiki/doku.php/?do=search&id=cutdown
[22:17] <Laurenceb> Akadecca: hot resistor cutter - http://wiki.ukhas.org.uk/_detail/projects:dscn1015.jpg?id=projects%3Aaerosol&cache=cache
[22:17] <rocketboy> so for example A xor B is a read-modify-write - which could get intterrupted mid instruction on some processor architechtures
[22:17] <Akadecca> just says No input file specified
[22:17] <jatkins> http://www.pegasushabproject.org.uk/wiki/doku.php?do=search&id=cutdown
[22:18] <Akadecca> does avr have a CAS primitive?
[22:18] <jatkins> it's just the extra / in the uri
[22:18] <Akadecca> yeah, wonder why it is adding it
[22:18] <Laurenceb> Akadecca: whats a CAS?
[22:18] <Akadecca> Compare And Swap
[22:19] <Laurenceb> oh not sure

[22:19] <Akadecca> an atomic update operation on larger procs
[22:19] <jcoxon> okay
[22:19] <Laurenceb> right
[22:19] <Laurenceb> ever worked with avr?
[22:19] <Akadecca> i guess when you're not dealing with threads its just a matter of disabling interupts
[22:20] <Akadecca> no, never worked with avr. 8051, pic and arm though
[22:20] <rocketboy> (good plan)
[22:20] Nick change: Akadecca -> akawaka
[22:20] <akawaka> rocketboy: not a fan?
[22:21] <akawaka> Laurenceb: got any more details on the resistor cutdown?
[22:21] <Laurenceb> fraid not
[22:22] <Laurenceb> its just a 10 ohm 1/8 watt resistor
[22:22] <rocketboy> or see http://wiki.ukhas.org.uk/ideas:flight_support
