[00:00] <cablito2> 2 goals. Open source project. I want to outline with precision all thats been done and how
[00:00] <jcoxon> excellent
[00:01] <cablito2> Pictures - I want to get good pictures and temperature data, really good pictures is a must
[00:01] <cablito2> I want to push this into universities
[00:01] <jcoxon> well that sounds really cool cablito2
[00:01] <jcoxon> certainly an interesting approach
[00:01] <cablito2> to get them involved and then move into really hard-core tech experiments.
[00:01] <jcoxon> i've always intended to recover my payloads
[00:02] <jcoxon> totally different style of thinking is required
[00:02] <cablito2> That seems to be what most people want, they all recover payload.
[00:02] <cablito2> Also not recovering payload brings more of a "challenge"
[00:02] <cablito2> if the comm does not work
[00:02] <cablito2> you have a total failure
[00:02] <jcoxon> certainly a different challenge
[00:03] <jcoxon> if the coms don't work and you want to recover its again a total failure :-p
[00:03] <cablito2> I can actually get funds from a research fund in brazil
[00:03] <jcoxon> thats cool
[00:03] <cablito2> but I want to do it with my own cash to show how it can be achieved
[00:03] <jcoxon> yeah
[00:04] <jcoxon> out of interest how did you find hte channel?
[00:04] <cablito2> oooo, i saw a site last night
[00:04] <cablito2> I´ve been studiying this for quite a while (about an year)
[00:04] <jcoxon> which site :-)
[00:05] <cablito2> I cant remember what site it was, its an uk one
[00:05] <cablito2> trying to check my history
[00:05] <jcoxon> oh cool
[00:05] <jcoxon> hehe
[00:05] <jcoxon> it doesn't really matter :-)
[00:05] <cablito2> http://www.ukhas.org.uk/
[00:06] <cablito2> you wanna know what the final goal reallly is
[00:06] <cablito2> its kinda "embarassing" to say it before I actually launch one sucessfull mission, but no harm in dreaming. Thats where I want funding.
[00:07] <cablito2> I want to recover the payload.... but i want it to gracefully come down... fly down more preciselly.
[00:07] <jcoxon> wow
[00:07] <cablito2> So its 100% re-usable and can be used for various flights for universities researchs
[00:07] <cablito2> involving one or more universities with different courses
[00:07] <jcoxon> so something like a glider or steered parachute
[00:08] <cablito2> a glider
[00:08] <cablito2> a guy tried before
[00:08] <cablito2> but it did not go that well
[00:08] <jcoxon> lots have
[00:08] <jcoxon> there is a guy in new zealand who has a working one
[00:08] <jcoxon> www.gpsboomerang.com
[00:09] <cablito2> 2.4 km
[00:09] <cablito2> my mistake
[00:09] <cablito2> 7km
[00:10] <cablito2> 7km is still too low
[00:10] <cablito2> airliners go there every minute :)
[00:11] <jcoxon> hehe
[00:11] <cablito2> you notice the glide ratio is really low?
[00:12] <cablito2> i´d guess under 8:1
[00:12] <cablito2> actually by visual its more like 3:1
[00:13] <jcoxon> haven't really looked into it
[00:13] <cablito2> 3:1 is not gliding, its almost like falling sideways :)
[00:13] <jcoxon> hehe
[00:13] <jcoxon> right well cablito2 i'm gonna have to go
[00:13] <jcoxon> good to chat to you
[00:13] <cablito2> all right
[00:13] <cablito2> cya sometime

[19:08] <icez> hey jcoxon
[19:08] <jcoxon> hi icez
[19:09] <icez> how are you?
[19:09] <jcoxon> good thanks
[19:09] <jcoxon> though haven't done enough work today :(
[19:10] <icez> lol, I've been doing nothing for a few days, I decided to start working :P
[19:11] <jcoxon> am now trying to find some source code to use the pic compiler i found for linux
[19:11] <jcoxon> need an example of a program
[19:12] <icez> which compiler is it?
[19:12] <jcoxon> SDCC
[19:13] <icez> seems there are examples in sdcc/device/examples directory of the source
[19:14] <jcoxon> not for a PIC though
[19:14] <icez> oh:/
[19:14] <icez> http://ubicomp.lancs.ac.uk/~martyn/sdcc_linux/
[19:15] <icez> maybe
[19:15] <icez> has examples for a few PICs
[19:15] <jcoxon> on there now

[20:35] <icez> hi LaurenceB
[20:35] <LaurenceB> hi there
[20:36] jcoxon (n=jcoxon@jac208.caths.cam.ac.uk) left irc: "Ex-Chat"
[20:39] <LaurenceB> I've come up with an idea for how to make a valve controlled balloon
[20:39] <LaurenceB> use a 15mm ball valve and a servo, ball valves don't need much torque
[20:40] <LaurenceB> then fix the 15mm (metal) valve into plastic pipe, and epoxy this into 35mm(or whatever it is) waste pipe for the balloon to fit over
[20:41] <LaurenceB> I've already developed servo control routines to use with avrs
[20:41] <LaurenceB> should all weigh approx 300 grams or so
[20:42] <LaurenceB> you can fix the helium hose on the end of the valve to inflate the balloon
[20:54] <LaurenceB> anyway that should make a very nice payload, I may try and make it at uni later this term :)
[20:58] <LaurenceB> bbl

[21:17] Action: jcoxon doesn't like PICs
[21:39] <LaurenceB> use avr
[21:40] <jcoxon> hehe
[21:40] <jcoxon> i'll survive
[21:42] <jcoxon> i'm mainly fussing as i have to use a budget windows laptop
[21:43] <max00> evening guys
[21:44] <LaurenceB> try bascom avr , the demo is free and teres lots of help on the forum
[21:44] <jcoxon> don't have a programmer etc
[21:44] <jcoxon> while i do have a pic programmer and pic set up
[21:44] <jcoxon> i'll battle my way through :-D
[21:45] <jcoxon> hey max00
[21:47] <max00> got a email saying my gps wont be posted till friday
[21:48] <max00> :(
[21:48] <max00> doesnt really matter as i dont have a router yet to play with
[21:50] <jcoxon> oh well
[21:51] <jcoxon> soon :-)
[21:51] <max00> yuh ive got a spare sd card
[21:51] <max00> so might set it up to go wardriving
[21:51] <max00> then work on a payload
[21:53] <jcoxon> cool
[21:53] <LaurenceB> bbl
[21:57] <max00> just got one of these...

[22:16] jcoxon (n=jcoxon@jac208.caths.cam.ac.uk) left irc: "Leaving"
[23:29] <LaurenceB> build one with a pic or avr :-)
[23:30] <max00> thought about buiding one but didnt think it would look very good
[23:31] <LaurenceB> thats the point, if it looks homemade the better
[23:32] <max00> i need to find some thing to learn to solder on
[23:33] <LaurenceB> you can try and fix my tv
[23:35] <max00> whats up with it?
[23:36] <LaurenceB> vertical scan coil not working

[23:44] <LaurenceB> have to kick it
[23:56] <LaurenceB> really want to make a valve for a payload
