[00:00] <defy> total used free shared buffers

[00:00] <phatmonkey> nope, versions here on ubuntu, my slug and debian and on freddie's gentoo machine all use almost 30mb in the console!
[00:00] <phatmonkey> 30MB of ram
[00:00] <defy> thats with 5 perl daemons running
[00:00] <phatmonkey> interesting
[00:00] <defy> and they are all hammering the cpu and i2c
[00:00] <phatmonkey> oh well, C is certainly best for speed!
[00:00] <phatmonkey> how often are you calling i2c-io?
[00:00] <defy> oh of course :P
[00:00] <defy> as fast as it will let me
[00:01] <defy> about 30 times a second
[00:01] <defy> its just in a while(1){} loop
[00:01] <phatmonkey> ok
[00:01] <phatmonkey> should be fine at around 10hz using the C library then!
[00:01] <defy> yeah
[00:01] <phatmonkey> i suppose 10hz is much enough for checking attitude
[00:02] <jcoxon> hey guys
[00:02] <jcoxon> silly question
[00:02] <phatmonkey> shoot!
[00:02] <defy> I'm hoping so, I average out my values a bit
[00:02] <jcoxon> i have a dallas 1820 temp sensor (1 wire)
[00:02] <jcoxon> and a gumstix connex and gpsstix
[00:02] <defy> my scripts take an argument, i think i've got them averaging every 5 polls
[00:03] <jcoxon> me want them to talk
[00:03] <defy> isn't 1wire just rs232?
[00:03] <defy> er way that made no sense, lol
[00:03] <defy> but doesnt it just use serial
[00:03] <phatmonkey> ADC on one of the GPIOs? i don't know much about it
[00:03] <phatmonkey> interesting - why are you averaging them?
[00:04] <jcoxon> i have a feeling it outputs digitally
[00:04] <phatmonkey> do they skip about?
[00:04] <defy> actually the thermopiles are okay, its the gyros i average, to cut down on any noise on the lines
[00:04] <defy> I haven't really noticed a need for it with the thermopiles
[00:04] <phatmonkey> ok
[00:04] <defy> but the gyro can just around a little bit, especially when adding more than 3 things to the ADC lines on the robostix
[00:05] <phatmonkey> my thermopiles are going to be connected via a 2 ft cable, which is going to be really dodgy
[00:05] <defy> it seems the more things i add, the more noise there is, which makes sense I guess...I've been told to cut it down by powering the sensors seperately
[00:05] <phatmonkey> they output a tiny tiny voltage, i will have to shield it carefully
[00:05] <phatmonkey> ok
[00:05] <phatmonkey> might need averaging i suppose
[00:06] <phatmonkey> i shall have to seee when i get it
[00:06] <defy> I haven't really done any good outside tests with the thermopiles though
[00:06] <defy> its been too cold :P
[00:06] <phatmonkey> for you or the thermopiles? :D
[00:07] <phatmonkey> it was the hottest day in july since records began yesterday, you are lucky ;)
[00:07] <defy> hehe
[00:07] <defy> me :P
[00:08] <defy> ah I'd much rather have hot, I was in california last week...it was 106 and I was loving it
[00:08] <phatmonkey> wow
[00:08] <phatmonkey> i do prefer mild weather, suppose that's what we normally get here
[00:09] <defy> hehe
[00:09] <phatmonkey> ah well, if you want to pinch any code, do give me a shout
[00:10] <phatmonkey> are you using any algorithms for the thermopiles?
[00:12] <defy> nah not yet
[00:13] <defy> the local rc store here has started selling those strong foam twinstar and microjet planes, but they are selling them at about 3 times the price they should be...typical
[00:13] <defy> I'm still not sure what airframe to use
[00:14] <phatmonkey> twinstar would be good for developing an autopilot on
[00:14] <phatmonkey> stable and can carry weight
[00:14] <defy> yea
[00:14] <phatmonkey> i was considering getting one, but i can't really afford another plane!
[00:15] <defy> hehe, i know the feeling
[00:15] <phatmonkey> *hopefully* there shouldn't be too much more money spent after i have got the thermopiles working and a parachute
[00:15] <defy> i had 5 planes in storage in cali i wanted to bring back and just couldn't find the time to package them

[00:16] <defy> im gona go fly the heli while its calm outside, bb in 20
[00:16] <phatmonkey> ok
[00:16] <phatmonkey> see ya
[00:16] <phatmonkey> i need some sleep... night all
[00:16] <defy> later :)

[00:29] <Tiger^> Further, a radio modem integrated with the sensor suite allows a D-variant Apache to share targeting data with other AH-64Ds and AH-64As that do not have a line-of-sight to the target. In this manner a group of Apaches can engage multiple targets but only reveal the radome of one D-variant Apache.
[00:29] <Tiger^> uh, nice.
[00:40] <jcoxon> hehe
