[08:58] <natrium> zeusbot is lame?
[08:58] <jcoxon> yup
[08:59] <jcoxon> sorry about that, still haven't worked out how to stop him getting angry about not being admin
[08:59] <jcoxon> how are things natrium
[08:59] <jcoxon> ?
[09:00] <natrium> not bad, preparing to go back to U i guess
[09:01] <natrium> you?
[09:01] <jcoxon> not bad, though am writing up a project right now, its really dragging
[09:02] <jcoxon> i owe you a gm862
[09:02] <jcoxon> (shall email you about it)
[09:02] <natrium> i don't need it in the immediate future
[09:03] <natrium> how's firefly II ?
[09:03] <jcoxon> coming along quite nicely
[09:03] <jcoxon> i've been redoing my code
[09:03] <jcoxon> made a morse library to get the code out hte way
[09:03] <jcoxon> also have been working on my mac os x software for uploading to the module
[09:04] <natrium> neat, i might be interested in that now :)
[09:04] Action: natrium runs parallels, but meh
[09:07] <jcoxon> just doing a screenshot
[09:10] <jcoxon> http://wiki.ukhas.org.uk/projects:firefly
[09:10] <jcoxon> the bottom text box i plan to make a text editor
[09:10] <jcoxon> but i'm having difficulties working out how actually to make it open a file
[09:11] <natrium> ah, looks good
[09:11] Action: natrium hasn't used objective-c before...
[09:12] <jcoxon> its in rubycocoa
[09:12] <jcoxon> which is great to be a beginnger with, but lacks documentation for the harder stuff
[09:12] <natrium> ah
[09:13] <jcoxon> but its apparently better on leopard
[09:13] <jcoxon> it should work but i can't test it
[09:13] <jcoxon> was in the apple store yesterday in london
[09:16] <jcoxon> tempted by a new apple
[09:17] <natrium> not going to wait for the next macworld?
[09:18] <jcoxon> oh i can't afford a new laptop
[09:18] <jcoxon> and i've got this one set up just right
[09:19] <jcoxon> even though its a little slow :-)

[13:12] <edmoore> hi neontube
[13:12] <edmoore> (better late than never)
[13:13] <neontube> ellol
[13:13] <neontube> up to anything fun?
[13:14] <edmoore> updating the firmware on my sony ericsson. so categorically not. it's an awful piece of software
[13:14] <edmoore> And I only have to do it because the first firmware revission kept crashing and hanging
[13:15] <neontube> u need a nokia 1110
[13:15] <neontube> nice
[13:15] <neontube> smiple
[13:15] <neontube> just does 'phone' and 'tex't
[13:15] <neontube> nothing else fancy
[13:15] <neontube> :P
[13:16] <edmoore> that is scarilly true. I really do need that
[13:16] <neontube> thats all they will let us have at work
[13:16] <neontube> only extra feature it has is an LED torch on the top
[13:17] <edmoore> do you work somewhere secure?
[13:17] <edmoore> a torch would be great - it's the only 'extra' feature i like having
[13:17] <neontube> lol no
[13:17] <neontube> i work for local government
[13:18] <neontube> its the cheapest phone :P
[13:18] <neontube> 20 quid sim free :P
[13:18] <edmoore> oh i see :)
[13:18] <edmoore> wow
[13:18] <edmoore> does it have a serial port?
[13:18] <neontube> a what?
[13:19] <neontube> got a charger socket
[13:19] <neontube> and ear phone / mic :P
[13:21] <edmoore> damn
[13:21] <edmoore> might make a nice gsm unit for a payload
[13:22] <neontube> the old 8210 was nice and small, but only had Infrared interface
[13:27] <neontube> bbl

[14:04] <neontube> ello lb
[14:05] <neontube> post man was late today ! only just turned up
[14:05] <neontube> now got a pair of radio module to play with
[14:05] <edmoore> awesome
[14:06] <neontube> i had to chase him up the street though
[14:06] <neontube> didn't wait long for me to get to te frount door to sign for it
[14:07] <neontube> glad i did otherwise its a 7 mile drive and a 2 day wait to go pic it up from the sorting office
[14:07] <Laurenceb> :P
[14:07] <Laurenceb> what type of module?
[14:07] <neontube> radiometrix rx2-433-40
[14:07] <Laurenceb> cool
[14:08] <Laurenceb> but with the standard rx you wont get much range
[14:08] <neontube> nope. just something to play with for now
[14:08] <Laurenceb> you'll need a SSB scanner for anything other than testing
[14:09] <Laurenceb> I'm trying to decide if I'm making a quad rotor or a micro rogallo
[14:09] <Laurenceb> I think a 60gram rogallo is possible :D
[14:09] <Laurenceb> 30cm wingspan
[14:09] <neontube> yup yup. mate of mine is into his radio stuff so has all of that gear
[14:09] <neontube> :)
[14:09] <Laurenceb> cool
[14:10] <Laurenceb> but a quad rotor might be more fun
[14:10] <Laurenceb> the problem is a quad rotor would need to be flown by hand - the nds motion card would only really be able to stabilise it I think
[14:11] <Laurenceb> so I'll probably make a rogallo
[14:11] <neontube> *doesn't know what quad rotor is ?
[14:12] <Laurenceb> http://en.wikipedia.org/wiki/Quadrotor
[14:12] <Laurenceb> what would be really nice is to have the lipo charge automatically off usb when its plugged in
[14:12] <neontube> tar
[14:12] <Laurenceb> I'm sure there is a really simple circuit but I havent worked it out yet...
[14:14] <Laurenceb> maybe a pnp and npn bjt... but maybe its possible to be even simpler
[14:14] <neontube> anyway, need to go do some shopping, c u guys later
[14:14] <Laurenceb> cya
[14:15] <Laurenceb> hmm I'm called "UV sensor data collection" interesting

[14:16] <Laurenceb> hey jcoxon
[14:16] <jcoxon> hey Laurenceb
[14:16] <edmoore> hi both
[14:16] <Laurenceb> hello ed :D
[14:16] <jcoxon> hey edmoore
[14:17] <Laurenceb> I've got my own lab :P
[14:17] <edmoore> my phone now has the new firmware from sony ericsson which stops it crashing then restarting every 20 seconds
[14:17] <jcoxon> Laurenceb: very cool
[14:17] <Laurenceb> the PC runs ubuntu
[14:17] <edmoore> it now just pulses the numberpaf backlight sinusoidally for no reason
[14:18] <jcoxon> edmoore: sony phones are rubbish
[14:18] <Laurenceb> which is cool
[14:18] <edmoore> well it's ok, I only have a 2 year contract :(
[14:18] <jcoxon> Laurenceb what are you going to do! no windows
[14:18] <Laurenceb> edmoore: I didn't write the firmware I swear honest
[14:18] <edmoore> lol
[14:18] <jcoxon> does sound laurence like firmware
[14:18] <jcoxon> only kidding :-p
[14:19] <Laurenceb> I'll have to install ubuntu on my laptop :D
[14:19] <edmoore> it is quite fun
[14:19] <edmoore> then you can go all gnuradio
[14:19] <edmoore> and take over the world
[14:19] <Laurenceb> Konversation is better than mIRC
[14:19] <Laurenceb> lol
[14:20] <Laurenceb> gnuradio is amazing but the hardware is expensive
[14:20] <jcoxon> oh you'll find that a lot of software on linux is better
[14:20] <jcoxon> and some of it isn't
[14:20] <edmoore> well you can still use a normal receiver
[14:21] <edmoore> but you've got your free rtty decoding etc
[14:23] flowolf (n=flowolf@host90-236-dynamic.2-79-r.retail.telecomitalia.it) left irc: No route to host
[14:25] <Laurenceb> free rtty?
[14:25] <edmoore> free rtty decoding
[14:26] <Laurenceb> cool, so there is a free alternative to truetty?
[14:26] <edmoore> it's a module in gnuradio, as far as i know
[14:26] <edmoore> I think it'd be a lot easier to make some ground control software based around gnuradio modules
[14:26] <edmoore> you could have the raw stream being decoded
[14:27] <edmoore> then use a script to parse all that lot and stick it in some kind of graphical interface
[14:27] <edmoore> or something
[14:27] <jcoxon> easypeasy
[14:27] <Laurenceb> sweet
[14:27] <Laurenceb> I'll look into this
[14:27] <Laurenceb> I was thinking of writing something to parse truetty output onder windows
[14:28] <Laurenceb> but this would be much nicer
[14:28] <edmoore> Are there any map databases?
[14:28] <Laurenceb> I'd use GE
[14:28] <edmoore> it'd be good if you could actually hard-save say a GB of ge
[14:28] <Laurenceb> with a networklink
[14:28] <Laurenceb> yes
[14:29] Action: jcoxon reaches for his gps enabled phone :-p
[14:29] <Laurenceb> have you seen the openmoko?
[14:29] <jcoxon> little bit of software and could auto decode position sms and plot them on the map
[14:35] <edmoore> isn't openmoko touted as the embodiment of why open source often doesn't work as well as tyranically closed source (eg apple)?
[14:36] <Laurenceb> lol ok
[14:36] <Laurenceb> it looks interesting
[14:37] <Laurenceb> my printer is called marvin :P
[14:37] <edmoore> the wizards assistant
[14:45] <jcoxon> edmoore: the data logger and camera arrived today
[14:48] <Laurenceb> uALFAT?
[14:48] <jcoxon> yup
[14:49] <edmoore> ooooh
[14:49] <Laurenceb> it looks nice
[14:49] <edmoore> that is exciting
[14:49] <Laurenceb> http://www.falconmodels.uk.com/acatalog/Power_units_and_Propellers.html
[14:50] <jcoxon> camera is nice, fixed the on switch problem
[14:50] <Laurenceb> I might get a PU05 for a micro rogallo
[14:50] <jcoxon> micro rogallo? dare i ask
[14:51] <Laurenceb> really small
[14:51] <Laurenceb> <60 grams
[14:51] <jcoxon> why?
[14:52] <jcoxon> (apart from cause you can)
[14:52] <jcoxon> is it for highaltitude?
[14:55] <edmoore> jcoxon, i've not been
