[17:22] <edmoore> ok cool
[17:22] <fnoble> are you coming tonight?
[17:22] <edmoore> digi has not arrived yet
[17:22] <edmoore> but it took me 2 days to order it afterwards. sorry. will keep you advised! should be soon though
[17:22] <edmoore> no, am out tonight
[17:22] <fnoble> want to start soldering stuff?
[17:22] <fnoble> ok
[17:22] <Laurenceb> everyone has orders :P
[17:23] <Laurenceb> this for the badger board?
[17:24] <fnoble> yeah
[17:24] <Laurenceb> sweet
[17:24] <Laurenceb> I'm too busy to make much :-(
[17:24] <fnoble> got some lassen iQs
[17:24] <Laurenceb> need to revise
[17:24] <fnoble> they are quite small
[17:24] <Laurenceb> sweet
[17:24] <fnoble> yeah, i should be revising too
[17:24] <Laurenceb> how many?

[17:24] <fnoble> 2
[17:25] <Laurenceb> ok
[17:25] <Laurenceb> from sparkfun?
[17:25] <fnoble> yup
[17:26] <Laurenceb> nice, I might get some from diamond point still
[17:26] <Laurenceb> depends how rich I am at the end of term
[17:26] <fnoble> edmoore: i got the pigtails for them and gm862s too
[17:26] <fnoble> going to SMA connectors
[17:26] <edmoore> yep that's a good idea
[17:27] <Laurenceb> hopefully my RC parafoil should arrive soon, I'll have to take some photos
[17:27] <edmoore> as we can use them for both then
[17:27] <jcoxon> good evening
[17:27] <Laurenceb> your going for the SMA adaptors?
[17:27] <fnoble> hi jcoxon
[17:27] <fnoble> yeah
[17:27] <Laurenceb> hi jcoxon
[17:27] <Laurenceb> ok, I was planning on the mini patch ants
[17:28] <fnoble> the SMAs are more versatile i think
[17:28] <Laurenceb> true, but bigger
[17:28] <fnoble> well, its easy to change
[17:28] <Laurenceb> did you get the smd socket for the module?
[17:29] <fnoble> ?
[17:29] <Laurenceb> for mounting it on the pcb
[17:30] <fnoble> oh yeah
[17:30] <Laurenceb> :-)
[17:30] <fnoble> cant use it without
[17:30] <edmoore> Laurenceb: who would make that kind of mistake?
[17:30] <Laurenceb> well you might have another way of using it
[17:30] <edmoore> witchcraft?
[17:31] <jcoxon> i would :-)
[17:31] <Laurenceb> cut off bottom of case
[17:31] <Laurenceb> through hole solder it :-)
[17:31] <jcoxon> well my ublox module arrived today
[17:31] <jcoxon> and of course it uses an obscure socket for hte gps antenna
[17:32] <fnoble> through hole!? the gm86s is like 0.5mm pith
[17:32] <edmoore> MMX?
[17:32] <jcoxon> MCXOSX
[17:32] <fnoble> *pitch!
[17:32] <jcoxon> MCX/OSX*
[17:32] <edmoore> fnoble: I pretended not to read it :p
[17:32] <fnoble> edmoore: might be a chance to try your hot air gun
[17:33] <edmoore> yep
[17:33] <edmoore> well it's sitting here
[17:33] <fnoble> it turns out the lassens use the same type of RF connector as the old uBloxs
[17:33] <edmoore> yes, the hufllepuffs
[17:33] <fnoble> the one on the gm862 is different, but it locks in quite positively, which i was a bit worried about
[17:33] <edmoore> that don't like being epoxied into place
[17:34] <jcoxon> fnoble, the sockets on the gm862 are mmx
[17:34] <jcoxon> i've got loads of connectors of those
[17:34] <jcoxon> well i've got a gps antenna with a lot of cable
[17:34] <fnoble> heh
[17:34] <jcoxon> so
[17:34] <fnoble> they are beautifully made connectors
[17:34] <jcoxon> are sockets important?
[17:35] <jcoxon> is it worth me sourcing a socket for this module
[17:35] <jcoxon> or can i remove it and solder directly
[17:35] <fnoble> i think the ubloxs fit into a plcc socket?
[17:35] <fnoble> its not that important though
[17:36] <fnoble> just handy sometimes
[17:36] <jcoxon> nah i've got a whole module
[17:36] <jcoxon> with pins and such
[17:36] <fnoble> ah ok
[17:36] <jcoxon> and a mcx/osx connector
[17:37] <Laurenceb> I've soldered one of the old u-blox modules by hand with no pcb before
[17:38] <edmoore> the very old ubloxes do
[17:38] <edmoore> the modern ones are their own packages
[17:38] <fnoble> edmoore: its so exciting, wont be long before the badger is complete
[17:38] <edmoore> well, one of two or 3 packages, anyway
[17:39] <edmoore> and up and away
[17:39] <edmoore> in ZP
[17:39] <fnoble> shhh!
[17:39] <edmoore> i mean, in latex
[17:39] <edmoore> there, no one noticed
[17:39] <Laurenceb> lol
[17:39] <fnoble> :)
[17:39] <Laurenceb> your using cortex m3 ?
[17:39] <edmoore> nope
[17:39] <fnoble> lpc2148
[17:39] <Laurenceb> ah
[17:39] <edmoore> 7tdmi-s
[17:39] <Laurenceb> running linux?
[17:40] <fnoble> 3prqm
[17:40] <edmoore> no....
[17:40] <fnoble> 7b-923
[17:40] <edmoore> why would you put latex on an arm7?
[17:40] <edmoore> i mean, linux
[17:40] <Laurenceb> lolz
[17:40] <Laurenceb> just an rtos
[17:40] <edmoore> it's vast and unecessary
[17:40] <fnoble> so it can generate nice PDFs of the gps coords
[17:40] <edmoore> and isn't even possible
[17:40] <edmoore> ok
[17:40] <edmoore> latex is not an rtos
[17:40] <edmoore> it's an os
[17:40] <edmoore> fuck!
[17:40] <edmoore> linux is not an rtos
[17:40] <Laurenceb> lmao
[17:40] <edmoore> it's an os
[17:41] <jcoxon> enough about you fetishes
[17:41] <Laurenceb> okok
[17:41] <edmoore> and it's huge
[17:41] <fnoble> there is realtime linux though
[17:41] <edmoore> and arm7s have no MMU
[17:41] <fnoble> which is a crappy rtos
[17:41] <edmoore> so you could only run uCLinux
[17:41] <Laurenceb> ah of course
[17:41] <edmoore> but you'd need one with an external mem interface and external mem
[17:41] <fnoble> anyway, we are runnin TNKernel, a realy minimal rtos
[17:41] <edmoore> we're running an rtos called TNKernel
[17:41] <Laurenceb> neat
[17:42] <Laurenceb> I need to try some of this
[17:42] <Laurenceb> might start with an AVR RTOS I guess
[17:42] <edmoore> AV AAAAARRGH!!! TOS
[17:42] <Cooleo64> Nooo. Euphoria-One just failed it first pre-flight test, The camera broke off =/
[17:43] <fnoble> edmoore: we need to make some rediculously gratiuitous I"C modules now :)
[17:43] <edmoore> Euphoria-One is an awesome name
[17:43] <Laurenceb> arggghh?
[17:43] <Cooleo64> Hehe, Thanks :)
[17:43] <edmoore> Sounds like what most guys have at about 13....
[17:43] <fnoble> * I2C
[17:44] <Laurenceb> what a (R)TOS ?
[17:44] <edmoore> real time operating system
[17:44] <fnoble> i propose an open challenge - to make the most ridiculous I2C module to fly on a balloon
[17:44] <edmoore> emphasis on real time
[17:44] <edmoore> so you have ahrdware interrupts and stuff
[17:44] <Laurenceb> I2C radio modem
[17:44] <fnoble> has to have some kind of point though
[17:45] <edmoore> the linux kernal isn't set up to support that
[17:45] <Laurenceb> that might even work quite well...
[17:45] <edmoore> it responds to stuff in a non pre-emptive way
[17:45] <edmoore> when it feels like it
[17:45] <edmoore> ~ms
[17:45] <fnoble> Laurenceb: our radio modem is going to be I2C
[17:45] <Laurenceb> oh
[17:45] <Laurenceb> so much for that plan
[17:45] <edmoore> everything is on i2c, so we can just add on whatever people want
[17:46] <Laurenceb> yes
[17:46] <Laurenceb> are you doing pulse shaping?
[17:46] <Laurenceb> RTTY
[17:46] <fnoble> havn't made the radio modem yet, going to use a rocketboy to start with i think
[17:46] <Laurenceb> ok
[17:46] <Laurenceb> thats serial btw
[17:46] <fnoble> i know, we will find a way to fit it on
[17:46] <Laurenceb> ok
[17:47] <Laurenceb> edmoore: what AV ARGGGHHHH ?
[17:47] <edmoore> AVR RTOS is a mouthful
[17:47] <edmoore> and you end up sounding like a pirate
[17:47] <Laurenceb> lol
[17:48] <Laurenceb> hrmf... need to do some work
[17:48] <Laurenceb> atmospheric physics is so chaotic
[17:48] <Laurenceb> doh accidental double meaning :P

[21:09] <edmoore> some pretty serious tech
[21:09] <Cooleo64> lol.
[21:10] <edmoore> you've pretty much run out of N-atoms by that point
[21:10] <Cooleo64> Wouldn't that get it into low earth orbit?
[21:10] <edmoore> you probably could orbit something at that point
[21:10] <Laurenceb> lol
[21:10] <edmoore> very large orbital decay, for sure, but not impossible
[21:10] <Laurenceb> your not going to get to 50km
[21:10] <Cooleo64> Ill be right back, I need to grab some food.
[21:10] <Cooleo64> I realise that :P
[21:10] <edmoore> it's been done, but it was just an empty balloon
[21:11] <edmoore> and a very big one
[21:11] <Laurenceb> maybe with a carbon nanofabric envelope
[21:11] <edmoore> it was done in the 60s LB
[21:11] <Laurenceb> not 50km?
[21:11] <edmoore> yup
[21:11] <Laurenceb> thought it was about 45 or so
