[00:00] <jcoxon> evening all
[00:01] <natrium42> hiya jcoxon
[00:03] <jcoxon> hey natrium42
[00:05] <natrium42> jcoxon, got a quickcam orbit af
[00:05] <natrium42> for launches :)
[00:05] <jcoxon> ooo cool
[00:06] <jcoxon> i ripped the ublox gps off my dead gumstix goliath board and wired it up
[00:06] <jcoxon> its super tiny and amazing
[00:06] <natrium42> cool
[00:06] <natrium42> that's something i was considering doing with mine too
[00:06] <natrium42> is it working ok?
[00:06] <jcoxon> yeah
[00:07] <jcoxon> lock in about 3 mins inside and its cloudy
[00:07] <natrium42> crazy
[00:07] <natrium42> gps receivers have come a long way
[00:08] <jcoxon> its ublox neo-4s
[00:08] <jcoxon> ublox are by far the best gps modules

[10:51] <Laurenceb> hi
[11:03] <jcoxon> hey Laurenceb
[11:05] <Laurenceb> jcoxon: I was thinking of buying three transceiver modules from sparkfun
[11:05] <jcoxon> okay
[11:05] <Laurenceb> would you be interested in setting one up - you seem to get good reception
[11:06] <jcoxon> i guess so
[11:06] <jcoxon> what would be required?
[11:06] <Laurenceb> 5V serial and a 434MHz ant with sma connector
[11:07] <jcoxon> i'm sure that could be arranged
[11:07] <Laurenceb> :P
[11:07] <Laurenceb> it'd be cool to try some tricks with networking
[11:08] <jcoxon> hehe
[11:08] <jcoxon> well i can definitly 'host' a transceiver
[11:08] <Laurenceb> it looks like they use the CC1020 IC, and probably use AFC mode
[11:09] <Laurenceb> so crystal drift shouldnt matter
[11:10] <jcoxon> http://www.flickr.com/photos/jcoxon77/3449926347/
[11:10] <jcoxon> :-)
[11:10] <jcoxon> took the ublox module off a dead gumstix board
[11:10] <jcoxon> and wired it up
[11:11] <Laurenceb> nice
[11:11] <Laurenceb> but you fried your goliath :-/
[11:12] <Laurenceb> did you ever get a lock with the lassen iq ?
[11:13] <jcoxon> Laurenceb, yeah, stuck it out side
[11:13] <jcoxon> Laurenceb, i'm not even sure what i did wrong with my goliath
[11:13] <jcoxon> usually i know when i break something
[11:15] <jcoxon> ublox modules are so much better then lassen's
[11:15] <jcoxon> and they aren't that expensive
[11:15] <jcoxon> well they are but not ridiculously
[11:17] <Laurenceb> yeah, I think the latency is low as well
[11:17] <Laurenceb> I want to buy one of the sparkfun modules with sarantel antenna, but they are sold out
[11:17] <jcoxon> i think there is an issue in getting the antennas themsevles
[11:18] <jcoxon> that would be a great module to use
[11:18] <Laurenceb> yeah... hope they get some more stock
[11:18] <jcoxon> Laurenceb, we should make one and sell them
[11:18] <jcoxon> there are no ublox suppliers in the UK
[11:19] <jcoxon> the engineering samples are about 75 euros for the chip
[11:19] <jcoxon> people would use them over the lassen anyday
[11:19] <Laurenceb> yeah
[11:19] <jcoxon> lassens have little annoying suprises
[11:19] <jcoxon> and aren't that sensitive
[11:19] <Laurenceb> I need to write a ublox binary protocol driver
[11:20] <jcoxon> just a breakout board with an antenna would be perfec
[11:20] <jcoxon> t
[11:20] <jcoxon> so that people can tap what every line they really want
[11:20] <jcoxon> or just an antenna socket

[19:29] <jcoxon> and i've fixed a few things so its better
[19:30] <jcoxon> that said the band was closed for me earlier
[19:30] <natrium42> so i should use the latest dlistener from the wiki?
[19:35] <jcoxon> ummmm the problem is that i don't really know their telem string
[19:36] <jcoxon> so yeah use the latest from the wiki
[19:36] <jcoxon> as it'll upload the raw logs as well
[19:36] <jcoxon> and i'll come up with a new version as soon as i see some valid strings

[20:45] <sbasuita> jcoxon, you ever thought about having some cool stats like this? http://www.df7cb.de/irc/pisg/pisg-month.html
[20:46] <jcoxon> i've considered
[20:46] <jcoxon> :-)
[20:46] <jcoxon> zeusbot is quite fragile
[20:46] <jcoxon> it gets upset rather easily
[20:46] <jcoxon> sbasuita, have you heard about this PBH launch?
[20:47] <sbasuita> jcoxon, no. Wasn't that the runaway one over newfoundland?
[20:47] <jcoxon> well they are launching again
[20:47] <jcoxon> tonight
[20:47] <jcoxon> (same guys)
[20:47] <sbasuita> ooh
[20:47] <sbasuita> what time?
[20:47] <jcoxon> 9pm EST is their plan
[20:47] <jcoxon> so its more like in the morning
[20:47] <jcoxon> but they are aiming for 50hr duration
[20:47] <jcoxon> so it'll be going tomorrow morning
[20:48] <sbasuita> nice
[20:48] <sbasuita> what they got onboard?
[20:48] <jcoxon> hopefully am going to rig the UKHAS network to go 'global'
[20:48] <jcoxon> 30m and 40m transmitters + 2m APRS transmitter, ballast systems as well
[20:49] <sbasuita> jcoxon, btw, the stats on that page are powered by 'pisg', which just reads logs and updates webpages
[20:49] <sbasuita> would be epic cool
[20:50] <sbasuita> Also, at the bottom of here they've got a nifty social network graph

[20:51] <jcoxon> yeah
[20:51] <jcoxon> thats why zeusbot is quite fragile
[20:52] <jcoxon> i have him on a shell account
[20:52] <sbasuita> A paid one?
[20:52] <jcoxon> and then he shunts teh data to pegasushabproject.org.uk

[22:57] <DanielRichman> that's the idea
[22:57] <DanielRichman> Changing the topic... With the radio module you mentioned that giving it 1.0V is a space and 1.2V is a mark... Could we use 0.2V and 0.0V or is that a bad idea? Requires one less resistor ;)
[22:58] <Laurenceb> it needs to be centered around Vcc_radio/2

[23:24] <jcoxon> ooo cool
[23:25] <DanielRichman> natrium, why do you need to compile it? isn't it in the repos?
[23:25] <natrium> not version 3.11
[23:25] <jcoxon> yeah its suprising
[23:25] <jcoxon> they only have 2.x something
[23:25] <natrium> http://www.w1hkj.com/Downloads.html
[23:26] <jcoxon> its come along way since then
[23:26] <natrium> ok, it's installed
[23:26] <DanielRichman> I wonder if its updated in jaunty... if not, a ppa is required. soon.
[23:26] <natrium> jcoxon, how do i run it again?
[23:27] <jcoxon> the dlclient?
[23:27] <natrium> no, fldigi
[23:28] <natrium> any command line options?
[23:28] <DanielRichman> version 3.03 is available in jaunty it seems; packaged in november so it just missed intrepid I guess.
[23:28] <jcoxon> no
[23:28] <jcoxon> 3.10 is whats needed for the dlclient as it uses some new features
[23:28] <jcoxon> no need for any cmd line args
[23:28] <jcoxon> though you'll need to turn on logging
[23:28] <jcoxon> its in the settings somewhere

[23:30] <jcoxon> natrium great
[23:30] <jcoxon> now for the client just run the client in the background
[23:30] <jcoxon> it'll first get you to setup a configfile
[23:30] <jcoxon> and then will quit
[23:30] <natrium> yah, ok
[23:30] <jcoxon> then run it again and it'll do its job
[23:31] <natrium> i am still fumbling with fldigi
[23:31] <jcoxon> no need for any cmd args if fldigi is running
[23:32] <jcoxon> once the PBH flight kicks off i'll get in touch with the Balloon_Sked list and #hamradio and recruite some listneners
[23:32] <natrium> just trying to set up audio input
[23:32] <natrium> no waterfall atm
[23:34] <jcoxon> okay will be on and off for a bit
[23:34] <jcoxon> bbiab
[23:35] <DanielRichman> What's the most efficient way to clear a bit on an IO register in AVR C? PORTD &= ~(_BV(PD4)); ?
[23:36] edmoore (n=edmoore@pomegranate.chu.cam.ac.uk) left irc:
[23:46] <natrium> yeah
[23:46] <natrium> though BV macro is deprecated i think
[23:46] <natrium> just do 1 << PD4 instead
[23:49] <DanielRichman> iirc its the sbi macro that went, they seem to still be using _BV in the manuals
[23:49] <DanielRichman> will double check that
[23:49] GeekShadow (i=Antoine@reactos/tester/GeekShadow) joined #highaltitude.
[23:49] <natrium> k
[23:50] <natrium> all programmers understand << :P
[23:50] <natrium> _BV ... nobody has heard of it
[23:51] <DanielRichman> that's gnu for you ;)
[23:52] <Laurenceb> is there a simple cmd line irc client?
[23:52] <natrium> irssi
[23:53] <Laurenceb> I'm thinking of having irc running over chipcon modules
[23:53] <Laurenceb> but avoiding overheads by having a simple protocol over the radio
[23:54] <Laurenceb> then connecting to a serve that runs an irc client
[23:54] <DanielRichman> you could gzip your communications
[23:54] <Laurenceb> hmm
[23:55] <DanielRichman> Or you could find commonly used words and swap them out for something binary...
[23:55] <DanielRichman> and gzip the rest... no idea.
[23:55] <Laurenceb> I'm more interested in integrating the text strings sent over the radio with irc
[23:56] <Laurenceb> its kind of a crazy idea but I think it'd be cool
[23:56] <DanielRichman> so... balloon => ground => irc?
[23:56] <Laurenceb> no ground users -> hab -> ground gateway(s)->internet -> co-ordination server -> irc
[23:57] <DanielRichman> Oh right, so you can get on IRC when there isn't an internet connection nearby?
[23:57] <Laurenceb> yes
[23:57] <Laurenceb> you could also share an internet connection via a hab
[23:57] <DanielRichman> The huge message of the day that the server dishes out every time you connect would be a killer
[23:58] <Laurenceb> hehe
[23:59] <Laurenceb> yeah tcp/ip would be cool
[23:59] <DanielRichman> Is it safe to rely on interrupts for UART action? Eg. I'm transmitting a string, I shove the first byte in and have an interrupt on UART_TX_vect to put the next byte in...?
[23:59] <Laurenceb> but to be sensible you'd run a simple chat protocol and then pipe it into irssi or something at the server
[00:00] <Laurenceb> that should work
