[12:20] <edmoore> bk
[12:21] <jcoxon> tis going well
[12:21] <jcoxon> am actually doing some work for once in my life
[12:22] <edmoore> :o
[12:23] <jcoxon> i've also sorted out some code to search for the phrase ATLAS in hte incoming data and then collect together a complete string
[12:23] <jcoxon> at the moment it stops collecting once the length exceeds a number
[12:24] <edmoore> cool
[12:24] <jcoxon> however i was thinking could we end our transmission with say a "Z"
[12:24] <jcoxon> or something so i can search for this
[12:24] <edmoore> how about
[12:24] <edmoore> 'This is project atlas, signing off'
[12:25] <edmoore> too much?
[12:25] <jcoxon> hehe, ummmm
[12:25] <jcoxon> a little
[12:26] <edmoore> or could be send the equivalent of tags?
[12:26] <edmoore> how about a geeky homage
[12:26] <edmoore> */
[12:27] <jcoxon> up to you, i can search for any character

[12:34] <Laurenceb> hi all
[12:35] <Laurenceb> so whats the plan with atlas?
[12:35] <Laurenceb> using the altoids can flight computer?
[12:35] <edmoore> yup
[12:37] <Laurenceb> cool

[12:45] <Laurenceb> hmm how much current can I send through a 0.6mm via ?
[12:48] <edmoore> god knows
[12:48] <edmoore> 1A?
[12:48] <edmoore> 2A?
[12:48] <edmoore> depends on plating I guess
[12:49] <edmoore> but, for instance, I'd be happy enough about powering a telit from one
[12:49] <Laurenceb> yes
[12:49] <Laurenceb> I've got cutdowns going through one
[13:03] <edmoore> hmmm
[13:03] <edmoore> could be tight
[13:03] <edmoore> could you stick some wire through it aswell?
[13:03] <edmoore> solder on both sides?

[13:43] <jcoxon> haha
[13:43] <jcoxon> and so you should be :-)
[13:43] <jcoxon> is that xchat off a pen drive or ubuntu off a pen drive?
[13:43] <RocketBoy_> ubuntu off a pen drive
[13:44] <jcoxon> good work
[13:44] <RocketBoy_> seems quite speedy
[13:44] <RocketBoy_> way better than windows
[13:44] <jcoxon> but of course
[13:44] <jcoxon> ubuntu still has its faults but its doing very well
[13:46] <RocketBoy_> I got a 2G USB stick by Dane elec - is not much bigger than my thumb nail
[13:47] <jcoxon> :-) , my thumbdrive has linux on it, but its set up to remove admin passwords on xp when people forget them
[13:47] <RocketBoy_> - so I got it up and running this morning - its got casper set up so the setting get written back
[13:47] <jcoxon> had 2 people in the last few months manage to completely lock themselves out
[13:47] <jcoxon> nice
[13:47] <RocketBoy_> ha ha
[13:48] <RocketBoy_> hum - xchat is quite different from mIRC
[13:49] <jcoxon> i really like xchat (what skin are you using?)
[13:49] <RocketBoy_> no idea
[13:49] <jcoxon> i prefer the classic to hte GTK2
[13:49] <jcoxon> by default you get the GTK2 i think
[13:49] <jcoxon> i wouldn't worry :-)

[14:36] <edmoore> we should all be
[14:36] <edmoore> sod it
[14:36] <edmoore> there's the atmosphere to explore
[14:37] <edmoore> LB- how's a launch soon looking?
[14:42] <Laurenceb> for the aerosol?
[14:42] <edmoore> yeah
[14:42] <Laurenceb> hmm... well I need to email my supervisor
[14:42] Action: Laurenceb sticks it on the list of jobs
[14:42] <Laurenceb> I've got too much stuff on the go
[14:43] <Laurenceb> it might have to wait until summer at this rate... I've only got 4 weeks til I'm going back
[14:43] <Laurenceb> then I'll really have to revise... if I can manage 6 hours a day I should crack it...
[14:44] <edmoore> it's far better that it's a prepared launch innit
[14:44] <Laurenceb> yes, I'm hopeing my supervisor can get things sorted, so I'm emailing him a load of code and instructions ect ect
[14:45] <Laurenceb> just hoping he doesnt fry everything...
[14:45] <Laurenceb> is google sketchup any good?
[14:46] <Laurenceb> for kitchen design?
[14:46] <Laurenceb> I'm looking for something where I can do good scale drawings
[14:46] <edmoore> No
[14:46] <edmoore> it doesn't do scale
[14:46] <edmoore> it doesn't really do parametric
[14:47] <edmoore> I don't really get it, tbh
[14:47] <edmoore> Just find it frustrating compared to normal cad tools
[14:47] <Laurenceb> hmm maybe I'd be better doing something in latex... ie just write code to do it
[14:47] <Laurenceb> I've got all the dimensions written down
[14:48] <edmoore> pencil and paper?
[14:48] <Laurenceb> that what I've just been doing
[14:48] <Laurenceb> 5mm graph paper :P
[14:49] <Laurenceb> but its nice to have it in digital form, more flexible

[19:45] <Laurenceb> yes
[19:45] <Laurenceb> thanx
[19:45] <Laurenceb> I'm working on the design now...
[19:46] <mc-> did you use the freerouting tool?
[19:46] <Laurenceb> http://wiki.ukhas.org.uk/projects:ukhas_glider_project:flight_computer
[19:46] <Laurenceb> nope
[19:46] <Laurenceb> how does it work?
[19:46] <mc-> http://www.freerouting.net/index.php?page=eagle
[19:47] <Laurenceb> so what does it do?
[19:47] <mc-> I think it's an autorouter, but better than the Eagle autorouter
[19:47] <Laurenceb> right
[19:47] <Laurenceb> well I'm over halfway now...
[19:48] <Laurenceb> but I might as well try it I guess

[20:00] <mc-> yes, webbased
[20:00] <Laurenceb> hmm I dont have java

[20:02] <RocketBoy_> BBL
[20:02] <Laurenceb> ok... I haven't got a clue what I'm doing
[20:03] <Laurenceb> IIRC theres a problem with java on this machine
[20:03] <mc-> yes, it needs java
[20:04] <Laurenceb> hmm not sure if its worth the effort...
[20:07] <Laurenceb> this is a bit over my head... theres so many java packages
[20:07] <Laurenceb> maybe I could swap to XP
[20:08] <Laurenceb> I'll need to find a usb stick to transfer the files....
[20:08] <mc-> only 1 java in XP, AFAIK
[20:09] <Laurenceb> yes, slightly simpler than about 20 packages
[20:09] <Laurenceb> I think I'll continue with hand routing it for the time being

[20:32] <mc-> I've been playing with the freerouter, it seems pretty good
[20:33] <Laurenceb> cool
[20:33] <Laurenceb> better than the eagle router?
[20:34] <mc-> I've never really used the eagle router, but I've seen other routers and they seem to place 1000s of vias
[20:35] <mc-> you can run the ulp in eagle, and then send me the file, and I can autoroute it for you, and send it back.
[20:36] <Laurenceb> thanx... I'll try and get down to 40 airwires first
[20:36] <Laurenceb> its my target for today :P
[20:37] <Laurenceb> what do I run the ulp on? a copy with all the tracks ripped up?
[20:37] <mc-> yes, or you can have some tracks routed.
[20:38] <mc-> it seems you need the components placed, but I might not understand it yet
[20:40] <Laurenceb> yes, my component placement is important
[20:40] <mc-> makes it harder for the autorouter if some components are placed badly
[20:43] <Laurenceb> ok well I'm at 44 airwires and this is giving me a headache...
[20:44] <mc-> I think I can't face doing any more routing ever again, this autorouter seems good enough
[20:46] <Laurenceb> hehe its so annoying
[20:46] <mc-> it seems to like the components far apart, then once it's done a routing, then you can try moving them closer together.
[20:46] <Laurenceb> especially when your trying to make a really compact board
[20:48] Rocketboy1 (n=grunge@217.47.75.147) joined #highaltitude.
[20:48] <mc-> how many tracks total do you have?
[20:48] <Laurenceb> this is complicated...
[20:48] <Laurenceb> 128 airwires
[20:48] <Laurenceb> odd, thats 2^7
[20:49] <mc-> the example it shows have 600+ tracks
[20:49] <mc-> it would rip through 128
[20:50] <Laurenceb> ok... I've made a copy and ripped up all the tracks
[20:51] <Laurenceb> for some reason there are now only 120 airwires... I think its the ground plane
[20:51] <Laurenceb> now I run the ulp?
[20:51] <mc-> there's a ULP icon in the icon bar
[20:52] <Laurenceb> right
[20:55] <Laurenceb> ok, sending you the file
[20:55] <Laurenceb> are you getting it?
[20:55] <Laurenceb> shall I email it?
[20:55] <mc-> try again
[20:55] <mc-> it got ignored
[20:55] <mc-> or email it
[20:56] <mc-> best email it, can't work out how to unignore
[20:59] <Laurenceb> ok, sent
[21:02] <mc-> not got it yet
[21:03] <Laurenceb> sent it to "fireflynet"
[21:03] <mc-> ok
[21:04] <mc-> it's routing
[21:04] <Laurenceb> cool, thanx
[21:05] <Laurenceb> have you got the components and everything ok?
[21:06] <mc-> seems to, it has lots of round pads at the top
[21:07] <Laurenceb> yep
[21:07] <mc-> it routed it all, and then started again.
[21:07] <Laurenceb> what size?
[21:07] <Laurenceb> 10mil?
[21:08] <mc-> not sure
[21:08] <mc-> but the tracks looks reasonably thick
[21:09] <mc-> on its 6th pass now
[21:09] <Laurenceb> sweet, how many vias?

[21:10] <mc-> around 30 at a glance
[21:10] <Laurenceb> wow, not bad
[21:11] <Laurenceb> any idea how to do a via count in eagle?
[21:11] <mc-> no idea
[21:14] <Laurenceb> has it finished?
[21:14] <mc-> pass 10, I don't know when it will stop
[21:14] <mc-> the fan is going crazy
[21:15] <Laurenceb> haha
[21:15] <Laurenceb> warm you hands :P
[21:15] <Laurenceb> all that brainwork released as heat :D
[21:16] <mc-> maybe you could help it by giving it some space around the side of the board?
[21:16] <Laurenceb> hmm
[21:16] <Laurenceb> I want 30x38mm
[21:16] <Laurenceb> is it doing the groundplane?
[21:17] <mc-> no
[21:17] <mc-> don't think that's possible with all the tracks
[21:18] <mc-> can you send me a sligher larger outline, then I can see if it suceeds ever.
[21:18] <mc-> pass 13
[21:19] <Laurenceb> has it routed everything?
[21:19] <mc-> the 'to route' figure gets to 0
[21:19] <mc-> but I think it has fails
[21:19] <mc-> which are part of the 128 airwires
[21:20] <mc-> so it then tries again in another pass
[21:21] <Laurenceb> well, in my hand routed version theres now 40 airwires
[21:22] <mc-> send me a larger outline, then at least I can see it route completely
[21:22] <Laurenceb> ok
[21:24] <Laurenceb> sent
[21:24] <Laurenceb> I attatched my hand routed version as well

[21:34] <Laurenceb> looks like ubuntu is doing the reboot loop trick again :(
[21:34] <mc-> I've removed your tracks now, how do I make the outline larger?
[21:36] <mc-> can you send me the original brd without gnd plane
[21:36] <mc-> and with a larger outline
[21:40] <Laurenceb> sorry
[21:40] <Laurenceb> was away, cooking
[21:40] <mc-> it doesn't like the gnd plane
[21:40] <Laurenceb> erm you can delete the groundplane
[21:40] <mc-> how?
[21:40] <Laurenceb> use the delete tool round the edge
[21:41] <Laurenceb> its a polygon
[21:41] <Laurenceb> well, a square polygon
[21:41] <Laurenceb> anyway, need to take care of cooking sorry
[21:41] <Laurenceb> thanx for the help, I'll bbl
[21:52] <mc-> it's starting routing now, with a larger outline
[22:04] <mc-> it's still struggling, so you would never have been able to route by hand
[22:04] <mc-> can you make some space around the Atmel chip, as it seems to have most vias there
[22:05] <akawaka> how many components on the board?
[22:05] <mc-> not sure, but 128 airwires

[22:13] <mc-> LB, sent you an email
[22:25] <mc-> I think it needs the components further apart to route
