[17:32] <edwardmoore> hi jcoxon
[17:35] <jcoxon> hey edwardmoore
[17:36] <edwardmoore> how's things?
[17:36] <jcoxon> good
[17:36] <jcoxon> have now finished lectures etc
[17:36] <edwardmoore> yaysome
[17:37] <edwardmoore> well i would want to work on some things this eve but i just remembered i have a formal swap. I was even in town and everything
[17:37] <edwardmoore> sigh
[17:37] <jcoxon> well we can start tomorrow
[17:37] <edwardmoore> yep
[17:40] <jcoxon> what time do you want to start tomorrow?
[17:40] <jcoxon> i'm now free all day
[17:40] <edwardmoore> 10ish?
[17:41] <edwardmoore> tonight could be rough- not sure
[17:41] <jcoxon> thats fine
[17:41] <edwardmoore> will have to dissappear for a DoS meeting in the early afternoon
[17:41] <jcoxon> np
[17:44] <edwardmoore> i've abandoned all pretensions of guidance before chute deployment, btw :)
[17:44] <jcoxon> excellent :-p
[17:45] <edwardmoore> well, i figure the first few should be from like 10,000 feet anyway
[17:45] <jcoxon> yeah
[17:45] <jcoxon> maybe in the future
[17:45] <edwardmoore> get that system nailed
[17:45] <jcoxon> once we have a working system
[17:45] <Metuk> Taking the easy way out again Ed?
[17:45] <jcoxon> in regards to tomorrow - give me a call when you are sober enough to work
[17:45] <edwardmoore> no.... incremental, evolutionary not revolutionary steps
[17:46] <edwardmoore> it's the engineering method, where it has to work or people get killed
[17:46] <edwardmoore> not just 'oh it's crashed' :P
[17:46] <Metuk> Blow me
[17:46] <edwardmoore> i will do jcoxon- not planning on getting too killed tonight
[17:46] <edwardmoore> tho robinson are bringing 3 bottles each
[17:46] <jcoxon> haha
[17:47] <jcoxon> good luck!
[17:47] <Metuk> Ed, do you still have that engineering penny thing that fits in a bottle?
[17:47] <edwardmoore> nope, em stole it
[17:48] <edwardmoore> not got time to make any more either
[17:51] <jcoxon> i'll try and read that nasa paper before tomorrow as well
[17:51] <jcoxon> damn it
[17:51] <jcoxon> found a problem
[17:51] <edwardmoore> it's good
[17:51] <edwardmoore> oh?
[17:52] <Metuk> What's the NASA paper on?
[17:52] <jcoxon> edwardmoore, basically i can't transport teh helium home
[17:52] <jcoxon> but then i just realised that you could :-D
[17:52] <edwardmoore> yep
[17:52] <jcoxon> i'm taking the train
[17:52] <edwardmoore> although my car might be pretty rammed
[17:52] <edwardmoore> but i'm sure we'll find room
[17:52] <jcoxon> so if i ordered a tank could you pick it up on hte monday morning
[17:52] <edwardmoore> chris - parafoil dynamics
[17:53] <jcoxon> i'll bring it back in my car
[17:53] <Metuk> Cool, link?
[17:53] <jcoxon> i'll do that tomorrow then
[17:55] <edwardmoore> metuk - digging it up
[17:56] <edwardmoore> this is the one on the testing technique which is useful
[17:56] <edwardmoore> http://pdf.aiaa.org/getfile.cfm?urlX=24WIG7D%2FQKU%3E6B5%3AKF5%2B%5CS%2A%5B%3B%0A&urla=%26%2A%22H%20%21PJJ%0A&urlb=%21%2A%20%20%20%0A&urlc=%21%2A%20%20%20%0A&urld=%27%2ARP%23%22%40%2AJW%40%20%20%0A&urle=%27%2AR%5C%25%2202AT%40%20%20%0A&urlf=%27%2AR%5C%25%2202GT0%20%20%0A
[18:01] <Metuk> Built a simulator yet?
[18:02] <edwardmoore> some matlab stuff
[18:02] <edwardmoore> don't really need to simulate being that
[18:02] <Metuk> Pretty dependant on your conditions I guess
[18:03] <edwardmoore> the algorithms can be pretty flexible up to the point at which you can't attack into the wind. if you can't make headway there's pretty much nowt you can do
[18:03] <edwardmoore> we won't be launching this thing into nasty conditions tho
[18:19] <edwardmoore> jcoxon did you have a look at that landy?
[18:33] <jcoxon> landy?
[18:33] <edwardmoore> landrover
[18:34] <edwardmoore> http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ih=005&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=150101720892&rd=1&rd=1
[18:34] <edwardmoore> it's perfect beyond all reason
[18:35] Metuk (n=Metuk@dove.chu.cam.ac.uk) left irc:
[18:35] <jcoxon> indeed it is
[18:35] <jcoxon> but
[18:35] <jcoxon> we aren't getting it
[18:35] <jcoxon> not yet
[18:35] <edwardmoore> on a more realistic note...
[18:36] <edwardmoore> (yes i realise but it's nice to dream :p)
[18:36] <edwardmoore> a tracking yagi
[18:36] <edwardmoore> did you get anywhere with the idea?
[18:36] <jcoxon> i was thinking that
[18:36] <jcoxon> it really wouldn't be difficult
[18:36] <jcoxon> i was thinking of just getting a usb powered motor driver thingy
[18:36] <jcoxon> and setting it up
[18:36] <edwardmoore> if it knew it's gps position and where it was pointing, and you fed it the balloon position, you'd be laughing
[18:37] <jcoxon> exactly
[18:37] <edwardmoore> it could be done happily enough on a PIC too
[18:38] <jcoxon> but what i thought we could do is have it off our ground 'puter
[18:38] <jcoxon> and then radio as well
[18:38] <edwardmoore> running from the ground puter?
[18:38] <jcoxon> yeah
[18:38] <jcoxon> 'puter or 'puters
[18:38] <edwardmoore> yeah- i mean the pic could be fed the gps position of the thing
[18:38] <jcoxon> oh right
[18:38] <edwardmoore> i kinda wanted to run a network inside the base-station landy ;P
[18:39] <jcoxon> http://www.active-robots.com/products/motorcon/servo-phidgets.shtml
[18:40] <jcoxon> though thinking about that we could make one for less
[18:40] <edwardmoore> oh god yeah
[18:40] <edwardmoore> 4 servos for £100? madness!
[18:40] <jcoxon> or how about a gumstix with gps etc
[18:40] <edwardmoore> for my walking robot i built 18-servo servo controllers and there was about £10 parts in them
[18:40] <jcoxon> usbnet to the gumstix
[18:40] <jcoxon> it also grabs the gps
[18:40] <jcoxon> and then pipes it to the 'puter
[18:41] <jcoxon> gives us some serial ports
[18:41] <edwardmoore> true
[18:41] <jcoxon> no reason why it couldn't also receive data from the radio
[18:41] <jcoxon> and also run software pwm to move the yagi
[18:41] <jcoxon> have a webserver or something running on it
[18:42] <edwardmoore> ok so the gumstix does the receiving and pointing, and then feeds stuff to the computer?
[18:43] <jcoxon> yeah
[18:43] <jcoxon> which then just runs simulations
[18:43] <jcoxon> also gumstix is powered of the usb port
[18:44] <edwardmoore> cool
[18:44] <edwardmoore> this sounds good
[18:44] <jcoxon> right i have to go - jcr handover dinner
[18:44] <edwardmoore> right, need to tart up for formal
[18:44] <jcoxon> call me tomorrow when you'r alive
[18:44] <edwardmoore> cya tomorrow!
[18:44] <edwardmoore> wow
[18:44] <edwardmoore> jinx
