[12:57] <jcoxon> hey Balders
[13:00] <Balders> hi
[13:00] <jcoxon> welcome to #highaltitude :)
[13:00] <Balders> tls
[13:00] <Balders> tks that is
[13:01] <jcoxon> :)
[13:01] <Balders> I was just looking at the pegasus site and saw this channel mentioned so I thought I would pop on and have a listen
[13:01] <Balders> are you involved in pegasus??
[13:01] <jcoxon> :-D
[13:01] <jcoxon> its a rather quiet channel
[13:01] <jcoxon> but slowly getting more visitors
[13:02] <Balders> yeah, the gumstix site has a link to the pegasus page, so that should generate a bit of traffic from people who use gumstix products (like me)
[13:02] <jcoxon> yes
[13:03] <jcoxon> pegasus is mine
[13:03] <jcoxon> :-D
[13:03] <Balders> ahh, nice!
[13:03] <jcoxon> thanks
[13:03] <Balders> well I was very impressed when I read
[13:03] <Balders> just reading the kernel hack for 8250 now..
[13:03] <jcoxon> hehe
[13:03] <jcoxon> very drity hack
[13:04] <jcoxon> dirty*
[13:04] <Balders> I have to do a kernel hack for the audio stix board that I am working on at the moment as the module for that board is not the best and does not support the features of the audio chip on board
[13:05] <jcoxon> oh righyt
[13:05] <jcoxon> just to say there is also a gumstix irc channel on freenode
[13:05] <Balders> ahh.. that may come in handy! thanks
[13:05] <jcoxon> is it an alsa driver?
[13:05] <Balders> nah oss
[13:05] <jcoxon> oh right - nice and old then
[13:06] <Balders> yep. but eaiser for me to understand :)
[13:06] <Balders> I am trying to use the netstix, connex, and audio stix for a VOIP endpoint type thingo
[13:07] <jcoxon> oooo very cool
[13:07] <Balders> embedding it in an operator console
[13:07] <Balders> anyhow, that has nothing to do with flying and altitude etc..
[13:07] <jcoxon> :D
[13:07] <Balders> I have other hobbies / interests that more pertain to this list..
[13:07] <jcoxon> i'm actually the only one that uses a gumstix here
[13:07] <jcoxon> phatmonkey, uses a hacked Slug router
[13:08] <Balders> In spare time (and the secret reason I am using gumstix at work to gt across) I am trying to create a self stablising hovering ducted fan flying thing.
[13:08] <jcoxon> right
[13:09] <jcoxon> you'll have to explain more... :-P
[13:09] <Balders> I currently have 3 fans in a triangle and an onboard robostix board with acceleroneters attached, then tethered to a laptop and the laptop can tell its orientation in space and control the fans..
[13:09] <jcoxon> oh wow
[13:09] <jcoxon> you plan to move to wireless?
[13:09] <Balders> I am in the process of trying to develop some type of control loop to drive the fans with the info I have from the accelerometers
[13:10] <Balders> maybe oneday.. At the moment I would be chuffed if I could just get the damn thing to hover!
[13:10] <jcoxon> cool
[13:10] <jcoxon> :-D
[13:10] <jcoxon> i guess a negative feedback system is too slow?
[13:11] <Balders> I have been reading up alot on the autopilot project and stealing an idea or 2, however I dont want to risk my heli's (as they cost to much) so the ducted fan idea is safer, cheaper, and indoors compatible!
[13:11] <jcoxon> i really like the idea
[13:12] <jcoxon> how well does the system function at the moment?
[13:12] <Balders> umm... I dont know yet, I get info from the accelerometers at about 20Hz, I have not as yet established the bandwidth of the ducted fans, so I dont know how fast I can drive them (i.e. change thrust)
[13:12] <Balders> well.. It has enough power to get off the ground and go crashunt in to a wall.. but there is no control feedback at the moment.
[13:13] <Balders> I have tried flying it by hand (by wiring up my heli remote to it) but I have not been sucessful..
[13:13] <jcoxon> :D
[13:14] <Balders> one of these days I should try and set up a web page and post pics and try and get some interest in it
[13:14] <willo> all that includes gyro/accel/temperature/motion-sensors turns me on ;p
[13:14] <Balders> heh
[13:14] <jcoxon> definitly
[13:14] <Balders> same
[13:14] <jcoxon> hehe
[13:14] <Balders> but is expensive and hurts the brain to think about the necessary kalman filters etc
[13:14] <jcoxon> the definitly part was for the webpage not being turned on, lol
[13:15] <Balders> how long have you been playing with these baloons etc?
[13:15] <jcoxon> me, not long
[13:15] <jcoxon> 6 months
[13:15] <Balders> oh really..
[13:15] <jcoxon> only done one launch
[13:15] <Balders> I assumed longer
[13:16] <jcoxon> synco, has done over 200!
[13:16] <Balders> I assume you saw the high altitude glider project
[13:16] <jcoxon> yes
[13:16] <jcoxon> i think its on my list of links
[13:16] <Balders> I saw that ages ago and I thought that was great!
[13:16] <Balders> ahh yeah.. so it is
[13:16] <jcoxon> thats what phatmonkey is making
[13:16] <Balders> ahh
[13:16] <jcoxon> and synco has a fully function system (well nearly)
[13:16] <Balders> what is synco's project?
[13:17] <phatmonkey> ooh, people
[13:17] <jcoxon> he is starting a company in NZ doing launches
[13:17] <jcoxon> hey phatmonkey
[13:17] <phatmonkey> I'll try and get the site up now
[13:17] <phatmonkey> hey
[13:17] <Balders> hi
[13:17] <jcoxon> synco, is http://www.gpsboomerang.com
[13:17] <Balders> what is the time whereever you people may be
[13:18] <jcoxon> 1.18
[13:18] <jcoxon> (am in the UK
[13:18] <jcoxon> )
[13:18] <Balders> k.
[13:18] <Balders> 12:18 AM 9Australia)
[13:19] <jcoxon> am at this point unpacking all my balloon stuff
[13:19] <jcoxon> just got back to uni
[13:19] <phatmonkey> 1:19 pm, surely?
[13:19] <phatmonkey> lol
[13:20] <Balders> what are you studing?
[13:20] <phatmonkey> at least it isn't the middle of the night down here
[13:20] <jcoxon> medicine
[13:20] <jcoxon> nothing to do with balloons, hehe
[13:20] <Balders> heh
[13:20] <willo> ;D
[13:21] <Balders> I am an electrical engineer whishing I had done aeronatical eng or something
[13:21] <jcoxon> :D
[13:21] <willo> and I have -no- education. ;D
[13:21] <Balders> heh
[13:21] <Balders> who needs it anyway!
[13:21] <willo> In fact, nothing *at all* ;)
[13:22] <willo> Working as a programmer in a phone company :P
[13:22] <Balders> embedded stuff?
[13:22] <willo> mostly perl. some php/c/c#
[13:22] <willo> perl for processing routes for the phonecalls, etc ;)
[13:23] <Balders> fair enough
[13:24] <Balders> so phone company as in telco rather than handset manufacturer
[13:24] <willo> Yup.
[13:24] <willo> in fact IP Telephone provider as well.
[13:27] <Balders> anyhow, I better get some sleep.. later..
