[00:23] <Laurenceb> can you stick an array inside a struct in c ?
[00:24] <SpeedEvil> static only of course
[00:24] <Laurenceb> static?
[00:25] <SpeedEvil> I mean of fixed length
[00:25] <Laurenceb> yeah
[00:25] <Laurenceb> multiple storage classes in declaration specifiers
[00:25] <Laurenceb> is what I get when I try to compile
[00:25] <SpeedEvil> Or a pointer
[00:29] <Laurenceb> typedef struct { u08 bytes[2]; u08 size;} varicoder_type;
[00:29] <Laurenceb> it doesnt compile
[00:34] <Laurenceb> nvm got it
[00:34] <Laurenceb> woohoo it compiles
[00:34] <Laurenceb> 2.4KB
[00:36] <Laurenceb> MFSK-64 as described here http://www.w1hkj.com/FldigiHelp/Modes/MFSKdesc.htm
[00:37] <SpeedEvil> I vaguely remember a stupid
[00:37] <SpeedEvil> oh
[00:37] <SpeedEvil> missing ;?
[00:39] <Laurenceb> nope, just some screw ups with datatypes

[01:30] <Laurenceb> thats untested as yet
[01:45] <Laurenceb> I'm considering making a transmitter from scratch... just not sure how the 10mw will work
[01:46] <Laurenceb> as in the commercial modules its a verified design

[17:58] <Laurenceb> Hmm looks like EEstor is busted
[17:59] <Laurenceb> I was quite intreaged by their idea, but I've found the flaw in their patent
[17:59] <Laurenceb> basically they coat barium titinate in alu oxide, and dont calculate the effect that has on overall permittivity correctly

[19:12] <edmoore> evening all
[19:14] <natrium42> hi GNU/edmoore
[19:14] <edmoore> did Stallman hypnotise you?
[19:14] <edmoore> did you just open my source?
[19:14] <edmoore> I'm feeling kinda wierd
[19:14] <natrium42> XD
[19:14] <edmoore> tingles a little
[19:15] <natrium42> but you *do* run gnu tools, right?
[19:15] <natrium42> so it's not nice to not mention gnu when referring to you
[19:17] <edmoore> how was the talk?
[19:17] <natrium42> it was... interesting
[19:18] <natrium42> but worth going to
[19:18] <natrium42> i did ask him why he only considers software, but not hardware
[19:19] <natrium42> since having a schematic of each appliance would be very nice
[19:19] <natrium42> so he said something about not being able to afford a fab etc
[19:19] <natrium42> it didn't really make sense
[19:19] <edmoore> that often happens
[19:20] <edmoore> did he talk about his semi-autistic categorisation or 'art' and 'not art' for the purposes of copywrite?
[19:20] <natrium42> also asked about firmwares being non-free
[19:20] <natrium42> he said that he considers them part of the hardware
[19:20] <natrium42> then i said that assembly code is also source code :P
[19:20] <edmoore> :)
[19:20] <natrium42> nah, i don't remember him talking about art
[19:21] <natrium42> bah, where is my SPOT device
[19:21] <natrium42> i thought it would arrive today :S
[19:21] <natrium42> mail didn't come yet
[19:23] <edmoore> SPOT?
[19:24] <natrium42> http://findmespot.com
[19:24] <SpeedEvil> oh.
[19:24] <SpeedEvil> Where is it?
[19:25] <natrium42> it's basically that globalstar module packed into a device with gps
[19:25] <natrium42> but with unlimited # of messages
[19:25] <SpeedEvil> snooping the module serial may be fun
[19:25] <natrium42> SpeedEvil, it should arrive today i hope

[19:52] <natrium42> weeee, i just got it :D
[19:53] <shellevil> :)
[19:53] <fergusnoble> natrium42: yey!
[19:53] <natrium42> but i have to send all the orders first :S
[19:54] <natrium42> (for my business)
[19:54] <shellevil> how much is a years service?
[19:54] <natrium42> $100 plus $20 (iirc) for continuous tracking
[19:54] <natrium42> so pretty damn cheap
[19:55] <natrium42> :)
[19:55] <fergusnoble> do you know what gps its got in it?
[19:55] <natrium42> not yet, going to open it up
[19:55] <fergusnoble> ok cool
[19:55] <fergusnoble> post pics :)
[19:55] <natrium42> after i mail the orders
[19:55] <natrium42> i will for sure :)

[23:39] <jcoxon> Laurenceb, check this out
[23:41] <Laurenceb> holy £4"$
[23:41] <Laurenceb> thats pretty cool
[23:43] <Laurenceb> dont know about the interface and limits tho
[23:43] Action: Laurenceb reads the datasheet
[23:44] <jcoxon> i just saw it on sparkfun
[23:44] <jcoxon> thought it might interest you :-p
[23:44] <jcoxon> sparkfun are so cool
[23:45] <Laurenceb> aha eithe rlimit but not both
[23:45] <Laurenceb> awsome
[23:47] <jcoxon> make a pcb!
[23:47] <jcoxon> oh and add an avr on for fun as well
[23:47] <jcoxon> the ultimate board
[23:48] <Laurenceb> yeah I was just thinking
[23:48] <Laurenceb> my radio mfsk code is small enough to fit on the main rogallo uC
[23:48] <Laurenceb> so I could stick that onto a pcb with the radio
[23:49] <Laurenceb> micro rogallo :P
[23:49] <jcoxon> hehe
[23:49] <Laurenceb> glue a micro servo on the back of the radiometrix case
[23:49] <jcoxon> Laurenceb, you need to launch something
[23:49] <Laurenceb> yeah
[23:49] <jcoxon> you haven't launched in years
[23:49] <Laurenceb> I want to get mfsk64 working
[23:49] <Laurenceb> then I'll be ready
[23:49] <jcoxon> fair enough
[23:50] <jcoxon> then wack together a payload and let it go
[23:50] <jcoxon> :-p
[23:50] <jcoxon> right i'm off to bed

[23:50] <Laurenceb> to be honest I'm more excited by the prospect of backfin gps
[23:50] <Laurenceb> cya
[23:50] <Laurenceb> woops
[23:50] <Laurenceb> s/prospect of/the blackfin gps
[23:50] <Laurenceb> :P
[23:51] <Laurenceb> seeing as its almost working now :D
[23:55] <natrium42> whoa
[23:55] <natrium42> nice find by jcoxon
[23:56] <natrium42> i requested a quote for 100 units from the manufacturer
[23:56] <Laurenceb> nice
[23:57] <Laurenceb> I prefer the idea of one of the BGA blackfin board with an SE4120 mounted on the back :P
[23:57] <natrium42> Laurenceb, how hard do you think it is to get a gps antenna right?
[23:57] <Laurenceb> depends
[23:57] <natrium42> i mean, just by using traces on the PCB
[23:57] <Laurenceb> if you want a patch, peasy
[23:57] <natrium42> yeah, patch antenna on PCB
[23:57] <Laurenceb> if you want a chip antenna, a bit harder
[23:57] <akawaka> wtf
[23:57] <Laurenceb> ok thats peasy
[23:58] <Laurenceb> just a ground plane
[23:58] <Laurenceb> and transmission line
[23:58] <akawaka> i'm gonna start a site selling that gps
[23:58] <natrium42> do you know how to do it?
[23:58] <natrium42> akawaka, NOOO
[23:58] <akawaka> i'll just ship black mosaic tiles instead
[23:58] <natrium42> akawaka, :D
[23:58] <Laurenceb> look at the datasheet ffor the patch
[23:58] <natrium42> which patch?
[23:58] <Laurenceb> then you just want a transmisson line to the module
[23:59] <Laurenceb> or ic in thuiis case
[23:59] <Laurenceb> whatever patch you want to use :P
[23:59] <natrium42> what i mean is making a pcb with a footprint for that gps chip and integrated pcb antenna
[23:59] <Laurenceb> so it goes something like patch mounted on board with ground pour on top
[23:59] <natrium42> so no patch antennas
[23:59] <natrium42> just the pcb itself
