[11:43] <Golfgeo> Hi all
[11:44] <Golfgeo> Got my Nslu2 up and running. Do need to configure a number of things before it is ready, but it's a start :-)

[23:13] <jcoxon> hey rocketboy
[23:16] <rocketboy> hiya
[23:17] <rocketboy> just been playing with some reaction wheels
[23:17] <rocketboy> based on a 32X CDrom motor (about 16,000RPM) and a aluminium platter
[23:18] <jcoxon> oh very cool
[23:19] <rocketboy> surprisingly - for a given torque it better to go with a light material and bigger wheel
[23:19] <jcoxon> i've just started constructing Peg V - finally got some connectors and a crimper
[23:19] <jcoxon> also have a 3 degree accelerometer
[23:19] <rocketboy> FB - when do you expect to fly it?
[23:19] <jcoxon> oh not for a while
[23:19] <jcoxon> well as soon as the weather calms
[23:19] <rocketboy> what sort of accelorometer
[23:20] <jcoxon> won't be for at least another 2 weeks
[23:20] <rocketboy> ok
[23:21] <jcoxon> http://www.sparkfun.com/commerce/product_info.php?products_id=692
[23:21] <jcoxon> the jetstream is awful right now
[23:21] <jcoxon> and will be for a bit longer
[23:23] <rocketboy> humm - cool chip
[23:24] <jcoxon> got henry to add it to his recent order
[23:24] <jcoxon> now its a matter of sorting out the ADCs on hte gumstix
[23:24] <rocketboy> I'm surprised AD havn't put on-board A2Ds
[23:24] <jcoxon> yeah
[23:25] <rocketboy> have you got 3 A2Ds?
[23:25] <jcoxon> had a chat with Ed Moore today - he is keen to help with any attempts at a parawing design
[23:25] <jcoxon> rocketboy, there are 4
[23:26] <jcoxon> on the GPSstix
[23:26] <jcoxon> they are off the audio chip thingy
[23:26] <rocketboy> Ah ok
[23:27] <rocketboy> I havn't launched my parawing yet - they were playing netball in the sports hall tonight
[23:27] <jcoxon> how did you make it?
[23:27] <rocketboy> its just not right - using a sports hall for sports
[23:28] <rocketboy> I bought it (£6 on ebay)
[23:28] <jcoxon> oh cool
[23:28] <rocketboy> its a parawing kite
[23:29] <rocketboy> like this one http://cgi.ebay.co.uk/Parafoil-Kite_W0QQitemZ260091168154QQihZ016QQcategoryZ2569QQrdZ1QQcmdZViewItem
[23:30] <jcoxon> was just looking at that
[23:30] <rocketboy> it saved me getting thesewing machine out
[23:30] <jcoxon> yeah
[23:30] <jcoxon> i might get one in a bit
[23:30] <rocketboy> I'll let you know how I get on
[23:31] <rocketboy> (and ed)
[23:31] <jcoxon> yeah i'd be interested
[23:32] <jcoxon> what i'm thinking is to Peg V has a look at apogee chaos
[23:32] <jcoxon> then Peg VI attempts 2 way comms
[23:33] <jcoxon> mean while i'll also explore parawings etc
[23:34] <rocketboy> yeah - there is so much to do
[23:36] <jcoxon> also want to set up a power kite rig to allow some low drop tests
[23:37] <jcoxon> was thinking of writing a little schedule - sort of list of things that need to be done
[23:37] <rocketboy> I tried lifting some weights on a kite -it surprising how big a kite you need
[23:38] <rocketboy> anyways I'm off - CU
