[11:45] <Balders> hello
[11:46] <jcoxon> hey
[11:46] <Balders> hey, do you know how to determine process utilisation on the gumstix??
[11:46] <Balders> there is no top and ps is severly crippled
[11:47] <jcoxon> hmmmm
[11:47] <jcoxon> i only use ps ax
[11:47] <Balders> did you roll your own ps or are you using the standard busybox one?
[11:47] <jcoxon> using hte busybox one
[11:47] <jcoxon> no reason why you can't compile top with the buildroot
[11:47] <Balders> eh.. that one ignores any flags like the ax
[11:48] <Balders> and it wont tell you proc time
[11:48] <Balders> oh well..
[11:48] <Balders> I will try and solve this one tommorow..
[11:48] <jcoxon> :D
[11:48] <jcoxon> the buildroot will help i'm sure
[11:48] <Balders> yep.. should do..
[11:49] <Balders> I wrote some code to get the audio stix playing a tone today, and next I have to write an ethernet handler to take packets off the ethernet and shove them out the audio port.. but I am keen to find out how much resources streaming 48kHz 16 bit audio is chewing
[11:49] <Balders> anyway.. not your problem..
[11:50] <jcoxon> :D
[11:50] <jcoxon> gumstix mailing list is also a good source of info
[11:51] <Balders> have you seen the maxstream rf modems btw??
[11:51] <Balders> http://www.maxstream.net/products/xtend/oem-rf-module.php
[11:51] <Balders> they are a little pricey, but they are light and they claim 60+ km range with an antenna
[11:52] <jcoxon> i've heard of them
[11:52] <Balders> k
[11:52] <jcoxon> i'll be interested in the legality of them
[11:52] <Balders> well.. they are in the 900MHz ISM band
[11:52] <jcoxon> oh jsut read that
[11:52] <Balders> well that is in Australia and USA anyhow..
[11:52] <Balders> I assume you have the same ISM bands over there
[11:53] <jcoxon> yeah
[11:53] <Balders> 900, 2.4G etc
[11:54] <Balders> you should ignore me on the other channel btw!
[11:54] <jcoxon> hehe
[11:54] <jcoxon> not sure how helpful i would be :-p
[11:54] <Balders> eh, just asking the same questions..
[11:56] <Balders> I applied for a web account today (free one) so hopefully I will get some stuff up soon..
[11:56] <jcoxon> cool
[11:56] <Balders> I have a get photos of my flying thing
[11:56] <Balders> get == few
[11:56] <jcoxon> :D
[11:56] <Balders> my brain is not working well at the moment
[11:56] <jcoxon> i'll be interested in attempting to use a radio modem
[11:56] <jcoxon> but worry about trying to track it
[11:56] <Balders> heh, yeah
[11:57] <jcoxon> it seems that the system is designed for stationary objects
[11:57] <Balders> how high to you get?? ~30km?
[11:57] <jcoxon> pegasus I went to 20km
[11:57] <jcoxon> the plan for II is to get above 30
[11:58] <Balders> did the cell phone reception work up at 20km??
[11:58] <jcoxon> no
[11:58] <Balders> heh
[11:58] <jcoxon> i lost contact for most of the flight
[11:58] <Balders> to be expected really...
[11:58] <jcoxon> i was using the worset phone ever
[11:58] <jcoxon> am using a slightly newer on this time
[11:59] <Balders> even still.. the antenna patterns from the cell sights generally do not radiate upwards..
[11:59] <Balders> once again... sights = sites
[11:59] <Balders> brain!!
[11:59] <jcoxon> hehe
[11:59] <jcoxon> yes thats very true
[11:59] <jcoxon> its not a problem
[12:00] <jcoxon> as long as it works when it lands
[12:00] <Balders> fair enough..
[12:00] <jcoxon> i'm actually quite happy with my set up
[12:00] <jcoxon> it worked suprisingly well
[12:00] <Balders> I was looking at the maxstream, as something I will probably get when I get to the stage of outdoors untethered flight..
[12:01] <Balders> as I will want realtime telemetry and control
[12:01] <jcoxon> :D
[12:01] <jcoxon> of course
[12:01] <jcoxon> right i've got to get back to work
[12:01] <jcoxon> off to the libary
[12:01] <Balders> ahh.. yes daytime for you..
[12:01] <jcoxon> indeed
[12:01] <Balders> cya

[18:45] <phatmonkey> :o
[18:45] <phatmonkey> now more powerbooks
[18:45] <phatmonkey> *no

[20:41] <jcoxon> right time to sort out this gnokii issue :D

[21:32] <synco> Might try another launch today.... although looking at http://squall.sfsu.edu/gif/jetstream_sohem_00.gif the jetstreams will be building up. What do you guys use to predict the direction of where the balloon goes???
[21:42] <jcoxon> hehe pure luck
[21:42] <jcoxon> no i used http://www.wunderground.com for jet stream maps
[21:42] <jcoxon> basically as long as the jet stream wasn't going east i was happy to launch
[21:42] <jcoxon> east=see
[21:43] <jcoxon> sea*
[21:43] <jcoxon> west = good
[21:45] <jcoxon> also checked the weather to make sure no cold fronts were coming in
[21:45] <jcoxon> luckly for my launch we had a bit of high pressure

[21:57] <synco> Ok. I know that some scientists use a special program for it although I haven't seen it yet.
[21:57] <jcoxon> there is a dos program on the internet somewhere
[21:57] <jcoxon> that the americans use
[21:59] <synco> Thanks... didn't realise wunderground actually did jetstreams. And in color!!

[22:02] <jcoxon> no probs
[22:02] <jcoxon> am wrestling with connecting the nokia to the gumstix
[22:04] <synco> Good luck.
[22:04] <jcoxon> :D thanks
