[21:38] lol [21:41] Ascension has tracking [21:47] Libreville has tracking [21:48] is there a rocket launch now? [21:48] yes [21:48] http://www.videocorner.tv/videocorner2/live_flv/index.php?langue=en [21:49] It's not by anyone here though. [21:49] yeah [21:50] Spain-South Korea [21:50] really these unmanned launches are only boring if they blow up [21:50] and Ariane as a whole has a good enough record for me not to care [21:50] Malindi has tracking [21:51] And they are very much a 80s design [21:51] yeah [21:51] but the boosters have been made better than the STS ones [21:52] Sure. [21:53] they're launching the next ATV to the ISS in February, that's a nifty little spacecraft. [21:53] yeah [21:53] and it is the 200th ariane [21:54] They're not really interesting for me, as they have very modest goals. [21:58] phew, I'm on a spending spree [21:59] just got the solenoid valve that zuph recommended for ballast control and the radiometrix radio for the APRS beacon [22:00] 2000 km [22:01] end of mission! [22:02] Action: SpeedEvil edits Arianes page on wikipedia to reflect launch success. [22:03] yay [22:04] spending sprees are always fun [22:06] hey stilldavid so starting your zp project? [22:06] jcoxon, it's sort-of officially started now [22:06] hi jcoxon [22:06] sweet [22:06] awesome - shout if you want any help [22:06] good luck! [22:06] going to start putting together the flight control system [22:07] jcoxon, you know I sure will. I've been thinking a lot about flight behavior... [22:07] when to drop ballast, etc... [22:07] good info here: http://spacenear.us/wiki/doku.php [22:07] i personally think a peristaltic pump will perform better then just a solenoid valve [22:08] and allows you to be quite accurate [22:08] definitely following halo as well as the white star guys; I'm on their mailing list and have been poking around some [22:08] jcoxon - "Programs for calculating various factors with ZP balloons" doesn't work [22:08] it worked for me [22:08] jcoxon, I just want to play with the pumps, I haven't decided on a ballast system yet. [22:09] what programs are on that link? [22:10] once i've fully flight tested my new flight computer i'll get on do another ballasthalo [22:10] could a heavy gas be used as a ballast? stored in a second balloon, and just released as necessary [22:10] http://mysite.verizon.net/milkyway99/id4.html [22:10] gets me a 404 [22:10] Lunar_Lander, oh right [22:11] i thought you meant the program didnt work [22:11] rather than the link [22:11] yeah [22:11] what does that program do? [22:11] exactly what it says [22:12] freezer test time [22:12] is there a way to get the program? [22:13] i'll have to go searching [22:13] follow the freezer test here: http://m6jcx.no-ip.org/dl-fldigi-XMLRPC/index.html [22:15] SpeedEvil1 (~user@tor/regular/SpeedEvil) joined #highaltitude.

[22:38] but capillary effects were screwing it up [22:38] well i've been working with williamson pumps [22:39] i use 2mm brass pipe with two insulated wires down the middle - twisted pair [22:39] http://www.williamson-shop.co.uk/100-series-with-dc-powered-motors-3586-p.asp [22:39] i plan to make them lighter [22:39] then measure the capacitance, but capillary effects and also broplets got stuck inside it [22:39] oh, that looks like it might just work [22:39] it needs to be slightly larger diameter to work [22:39] the ones I've seen are much bukier [22:39] thats what i've been working with on ballasthalo [22:39] maybe 3 or 4 mm diameter [22:42] stilldavid, its got some metal attachements that can be replaced with something more lightweight [22:42] http://www.sparkfun.com/products/7918 [22:42] that sensor ic [22:42] also photodiode and interrupter doesn't work as teh photodiode got too cold [22:42]
