[15:51] hi all [15:52] question: turns out i have a SIRF chip; how much does that suck [15:52] i think it just means your code is going to be more complicated [15:53] in what way [15:53] cant i just reset the thingy every 10 mins [15:54] what for ? [15:54] so that it does work? [15:54] i am not sure what happens after 24km [15:54] What GPS unit is it ? [15:54] VincotechGPS Firmware GSC3-based Products [15:54] A Description of the standard NMEA GPS firmware provided [15:54] on Vincotech’s GPS modules based on SiRFstarIII – GSC3 [15:54] A1080, A1084, A1088, A1035-D, A1035-H [15:55] so which model is yours ? [15:56] eh [15:56] a1080 [15:59] Tyco ? [15:59] hmm? [15:59] ahh Tyco = Vincotech [16:01] rharrison (~rharrison@gateway.hgf.com) joined #highaltitude. [16:02] so what about tyco? [16:03] hang on [16:05] i'd avoid sirfIII if you can [16:05] faaak [16:06] :'( [16:06] well if you are planning to track by radio that is [16:06] if just going for gsm and you reset it occasionally then thats fine [16:06] does it automatically go on below 24km? [16:06] some do, some don't [16:07] The A1080 was designed for indoor use [16:07] indoor! [16:08] it is totally worthless indoor [16:08] according to their flyers [16:08] I've a SIRFIII module that's really good indoors [16:09] yeah okay, but this is model that's below it, is apparently designed for indoors [16:09] cant even get a signal in front of a half open window! [16:10] i can't find any data concerning its altitude limits [16:10] yeah but dont all SIRFIII's have it? [16:10] earthshine: most SIRFIII's crash/loose lock above 24km [16:10] pshhh [16:10] then it's not a lot of use [16:10] not for tracking anyway [16:11] yeah unless you make it shut down after 20k, and reboot after 20 mins [16:11] you could reset it occasionally so at least you could find the payload after landing [16:11] yeah but the question is, would thát work [16:11] but you won't be able to find it in flight [16:11] well it's not guaranteed [16:11] hahaha [16:11] omg [16:11] timbobel: sure, that would work - if you cut the power to it you'll reset it fully [16:11] if i were you i'd look for a GPS module that is known to work [16:12] if it has a reset pin you could pull it low/high, that might work [16:12] if you can't afford that then do what juxta says [16:12] yeah allright but i have got almost everything finished. [16:12] Daniel cleared up my code last night a little :( [16:12] and what i had was ideal for the arduino [16:12] any suggestions? [16:13] hm [16:13] how are you using the module? [16:13] is it on a breakout board or something? [16:13] or an arduino shield? [16:13] modified shield, so it was a good fit [16:14] timbobel, i'd go for a lassen iq or a ublox gps [16:14] i have ordered some custom PCB stuff so it would fit perfectly [16:14] i prefer ublox [16:20] i have to say [16:20] SIRF chips are very popular [16:25] hmm [16:26] i am afraid i will have to shut it down for half an hour after he reaches 22k. is that a good idea?

[21:01] I'm using http://www.inventeksys.com/html/ism300f2-c5-v0004.html [21:01] but it's a rude word to work with as the pin spacing isn't standard and there are no break outs for it [21:01] The ISM300F2-C5-V0004 module is programmed with HIGH ALTITUDE BUILD, ceiling 135,000 feet, and works at cold temperatures for ballon applications. [21:01] nice [21:02] doesn't look impossible to solder with a decent nib [21:02] well I've already trashed one [21:02] and sirfIII is a great engine [21:02] Tryng to desolder it [21:02] They are only Ł22 each [21:02] I think solder ovens might be the way forward [21:03] we have a hot air solder station but I don't dare us it on this [21:03] Upu: where did you buy yours from?

[21:10] just don't both with venus chipsets [21:10] their dynamic performance is really pretty crap [21:10] this is a Zeus [21:10] Sadly they won't sell me a Titan chip :) [21:10] bastards [21:11] hi edmoore [21:11] military use only [21:11] hi jonsowman [21:11] hows things [21:11] not bad. i am making a presentation in a very unfocussed way, icing my right hand and typing with left [21:12] which is getting quite fast! [21:12] haha [21:13] been up to much the last week? [21:13] apart from learning to type fast one-handed? [21:14] plenty of work [21:15] fair enough [21:15] you? [21:15] started work today [21:16] oh cool - how is it? [21:16] yeh good [21:16] really interesting stuff [21:16] bit of a long commute but I can live with it for a few weeks [21:17] natrium42 (~natrium@CPE000625d867e2-CM0014045885be.cpe.net.cable.rogers.com) joined #highaltitude.

[22:40] am quite pleased with how it all went. now that we've sort of given up the strict observance of launch times [22:41] hehe [22:41] making a presentation [22:41] not going to have too late a night [22:43] am working on dl-fldigi [22:43] cool [22:43] have added an easy mode switch button [22:43] for dual format flights [22:43] once this is all out the way i will set myself up so I can build it and start playing [22:43] :-p [22:44] an excuse to work on the bayesian demodulation thingamie [22:44] hehe [22:44] SpeedEvil (~user@tor/regular/SpeedEvil) joined #highaltitude. [22:50] so yes, valve fun soon :) [22:50] indeed [22:51] i might do some mock designs oh what i've been thinking [22:51] for you to eyeball [22:51] cool [22:52] I suggest you whittle them out of cheddar. [22:52] but for now i really should go as my right hand is actually in agony and i am doing this left handed, but really need to push on [22:52] eek [22:52] :/ [22:52] will stay logged in but not v talkative [22:53] no problem [22:57] griffonbot, should track dl-fldigi changes as well! [23:07] github has an IRC hook built-in [23:08] hey stilldavid [23:08] haven't heard from you in a while [23:08] hey, been busy lately... hope to launch again this summer though! [23:08] great [23:08] Laurenceb (~laurence@host86-136-234-149.range86-136.btcentralplus.com) joined #highaltitude. [23:08] just found out there's a hab launch with 12 balloons a state away in about a month [23:08] i'd like to launch Peg VII again [23:08] LazyLeopard (~irc-clien@chocky.demon.co.uk) left irc: Quit: Bye [23:08] stilldavid, oh GPSL [23:08] gpsl? [23:09] snap [23:09] edmoore, yeah i got teh date wrong by a month [23:09] was going round saying it was now [23:09] oops :-p [23:09] jcoxon, yeah, that's it :) [23:09] stilldavid, go to it [23:09] it'll be amazing [23:09] was thinking of a stabilized camera payload [23:09] http://www.flickr.com/photos/stilldavid/4707795467/ [23:09] stilldavid: those guys have been doing it for decades [23:09] they know their bananas [23:09] yeah, it seems like it. I emailed back and forth with one of the organizers a bit last week [23:10] Action: jcoxon wishes he had sparkfun resources [23:10] paul v? [23:10] guy named Zack... [23:11] Zack Clobes [23:11] clobes [23:11] yeah [23:11] it'd be fun to go to a gpsl [23:11] jcoxon, I wish I had unlimited time... [23:11] er, infinite time rather [23:11] you should definitely try and get there [23:12] yes, regardless of whether I'm ready. I can re-use a lot of my last payload, though [23:12] stilldavid, i've got that for a bit [23:12] but I'm thinking servos for 2 axis then a stepper motor for the third vertical axis for infinite spinnability [23:12] Laurenceb (~laurence@host86-136-234-149.range86-136.btcentralplus.com) left irc: Ping timeout: 240 seconds [23:12] stilldavid, ed is the one to talk to about this :-) [23:13] you have infinite time for a bit? [23:13] i've just had a seg fault [23:13] free time [23:13] for a finite amount of time, yeah :) [23:13] analogmonster (~chatzilla@pool-173-51-69-215.lsanca.fios.verizon.net) joined #highaltitude. [23:13] edmoore, seg faults are the worst [23:13] stilldavid: re:stepper, bear in mind on that exis you have to react against something [23:14] you will find otherwise you're mainly just coiling the balloon line up [23:14] hm. can't think of a solution off hand to that. [23:14] which will then start to uncoil in a way that wont give you stable pics :) [23:15] well, easy enough to solve with a piece of fishing tackle or a joint from a kite [23:15] momentum wheels [23:15] junderwood (~John@adsl.jcu.me.uk) left irc: Quit: Leaving [23:15] yes, I was looking at some gyro type flywheels, but most are (understandably) heavy [23:15] you'll find the friction of a pivot to be huge relative to the kind of torques you are looking at [23:15] might have a friend machine one from aluminum. doesn't need too much mass I don't think [23:16] i think you need a way to actively decouple the gondola from the suspension [23:16] ... another stepper! [23:16] exactly! [23:16] and to decouple that.... [23:16] A Shrubbery! [23:17] a disclaimer is that my thesis was on stabilisation of small balloon gondolas [23:17] how high can an unladen swallow fly? [23:17] uh, pdf link please! [23:17] stilldavid: Alive or ballistically? [23:18] brennen (~brennen@68-64-214-18.static.forethought.net) joined #highaltitude. [23:18] i've been asked to keep tabs on it for a few weeks by my supervisor. it got me a decent distinction and so might get whipped into something publishable. but i will try and sort that ASAP [23:18] I'd love to read it in any state you can send it regardless of publishability [23:19] but no pressure or anything. It's probably over my head anyway [23:19] Action: SpeedEvil wishes magnetic bearings were simpler. [23:19] as the paper worthy stuff is kind of specificly nerdy bits of bayesian inference rather than the general project itself [23:19] SpeedEvil: my gap year job was building control systems for mag bearings [23:20]
