[16:34] <jcoxon> i was looking at your ngw100 earlier
[16:35] <Laurenceb> its pretty cool :P
[16:35] <jcoxon> have you tried logging in over usb?
[16:35] <Laurenceb> no
[16:35] <Laurenceb> it needs a driver installed
[16:35] <jcoxon> Laurenceb, its on fire...
[16:35] <Laurenceb> :P
[16:35] <jcoxon> yeah thats really easy with the linux kernel
[16:35] jatkins (n=jatkins@79-65-70-83.dynamic.dsl.as9105.com) joined #highaltitude.
[16:35] <jcoxon> just need to activate usbnet (its usb gadget)
[16:35] <Laurenceb> I might try it, using ssh at the moment
[16:36] <Laurenceb> but its glitchy
[16:36] <jcoxon> then it'll act like a network
[16:36] <jcoxon> and you can ssh in

[16:36] <jcoxon> its how i use to access teh gumstix
[16:36] <Laurenceb> sometimes it will refuse access and I need to change my ip address
[16:36] <Laurenceb> its kind of annoying, but its probably just me not understanding how it works
[16:37] <Laurenceb> brb, need so check some boards I'm etching
[16:39] flowolf (n=flowolf@host139-237-dynamic.2-79-r.retail.telecomitalia.it) left irc: Client Quit
[16:39] <Laurenceb> maybe I need to logout?
[16:40] <Laurenceb> jcoxon: have you ever used sony-ericcsson phones?
[16:40] <jcoxon> Laurenceb, no i'm a nokia person
[16:40] <Laurenceb> I'm thinking of using a T-610 on the aerosol payload...
[16:41] <jcoxon> if its AT commands i guess they'll be no difficulty
[16:41] <Laurenceb> yes
[16:41] <Laurenceb> off the rs232 on the ngw100
[16:41] <Laurenceb> I've turned off the terminal on there
[16:41] <jcoxon> then go for it
[16:41] <jcoxon> does it need to be rs232?
[16:42] <Laurenceb> no, but I have an rs232 port :P
[16:42] <jcoxon> as in will you have to shift down to the phone's levels?
[16:42] <Laurenceb> I've got a datacable
[16:42] <jcoxon> oh okay
[16:42] <jcoxon> i was looking at the boards - they are very cheap
[16:42] <jcoxon> i don't think you can find a cheaper linux board
[16:42] <Laurenceb> :P
[16:42] <jcoxon> but are quite big
[16:43] <Laurenceb> yes, not a problem for me
[16:43] <jcoxon> okay
[16:43] <Laurenceb> as its not the limiting factor
[16:43] <jcoxon> what voltage to they require?
[16:43] <Laurenceb> if you modify the board, 7v
[16:43] <jcoxon> right, cool
[16:44] <Laurenceb> in fact, if you went extreme and removed the switched more supply, 3.3V and 1.8V
[16:44] <Laurenceb> more=mode*
[16:44] <Laurenceb> if you want to use the power connector, 8.4 V
[16:44] <jcoxon> right
[16:45] <jcoxon> i'm weighing up my options for my next payload
[16:45] <Laurenceb> I've bypassed some diodes, so its more efficient
[16:45] <Laurenceb> but you can fry it if you give it reverse polarity
[16:46] <jcoxon> right

[16:50] <Laurenceb> its good to be able to run python
[16:52] <jcoxon> yeah
[16:53] <jcoxon> the telit modules are a little bit too expensive to lose especially with a gps that doesn't work above 24km
[16:54] <Laurenceb> this rf solutions gps isnt too bad
[16:55] <Laurenceb> sensitivity isnt too good, but its low current and works above 24Km
[16:55] <jcoxon> for $99 i could rebuild Peg I
