[00:00] <natrium42> which pre-amplifier did you use for receiver?
[00:00] <fuzzylugnuts> BBA-322-A
[00:01] <natrium42> cool
[00:02] <natrium42> wonder if it's legal to make a transmitter using those chips with basic license
[00:03] <natrium42> technically they are radios on a chip
[00:03] <fuzzylugnuts> its easier to beg forgiveness than ask permission
[00:03] <natrium42> :)
[00:04] <natrium42> for example, i can make my own cable to connect a regular transceiver to a regular amplifier
[00:04] <natrium42> isn't it the same on PCB scale? :)
[00:06] <fuzzylugnuts> er, kinda
[00:06] <fuzzylugnuts> you could make a sweet bi-directional amp out of those two modules and a t/r switch
[00:07] <fuzzylugnuts> I can't freekin believe this, no APRS traffic here
[00:08] <natrium42> hmm, let me check if i have any here

[00:08] <natrium42> yep, got it
[00:08] <natrium42> so that's how it sounds :)
[00:08] <fuzzylugnuts> my antenna is inside the apartment... but I should be hearing something
[00:09] <fuzzylugnuts> *kerrrrrrrRrRrrrRrrrrkkksh*
[00:09] <natrium42> hehe, that's what i heard
[00:09] <natrium42> need to connect my receiver to laptop
[00:10] <natrium42> old laptop, but major win since it has RS232
[00:10] <fuzzylugnuts> ahh nice
[00:10] <fuzzylugnuts> I've had good luck with usb>serial adaptors though
[00:12] <fuzzylugnuts> I -so- have to learn microcontrollers.
[00:13] <fuzzylugnuts> natrium42: are you in the UK?
[00:13] <natrium42> ontario
[00:14] <fuzzylugnuts> Ooooh ok
[00:14] <natrium42> where are you based?
[00:14] <fuzzylugnuts> usa, Tennessee
[00:15] <fuzzylugnuts> do you have funky TX power restrictions on radios at altitude?
[00:15] <natrium42> nah
[00:15] <natrium42> do you do HF?
[00:16] <fuzzylugnuts> Yeah, but I'm not set up for it right now
[00:16] <natrium42> ok
[00:16] <natrium42> i will have to test HF somehow once i set up my long wire antenna
[00:16] <fuzzylugnuts> full wave?
[00:16] <natrium42> full wave for 20 m
[00:17] <natrium42> 1/2 wave for 40m
[00:17] <fuzzylugnuts> nice
[00:17] <fuzzylugnuts> trapped?
[00:17] <natrium42> no, just horizontal wire
[00:17] <fuzzylugnuts> ok
[00:17] <natrium42> connecte to ATU on one end
[00:17] <fuzzylugnuts> ooh ok
[00:18] <natrium42> no idea how well that will work

[16:05] <edmoore> gordonjcp: yes, it's a nice project
[16:05] <edmoore> there's also an avr one to

[17:27] <edmoore> no, the internationla visiting commitee
[17:27] <edmoore> heads of department from other unis
[17:27] <edmoore> alec broers
[17:27] <edmoore> head of industries like the guy from DOW
[17:27] <edmoore> most of which arrived in helicopters
[17:28] <edmoore> we printed out james canvins poster to 3m long
[17:28] <edmoore> looks AAAAWESOME
[17:28] <fnoble> sweet
[17:28] <jcoxon> afternoon all
[17:29] <jcoxon> sorry i've missed all your pings
[17:29] <edmoore> no problem
[17:29] <edmoore> too late though, we've ordered
[17:29] <jcoxon> sparkfun?
[17:29] <edmoore> coolcomponents in the end
[17:29] <jcoxon> oh okay
[17:29] <jcoxon> wanted som 0.1 inch snap away headers
[17:29] <fnoble> hmm, maybe we can just crib most of the design of the cpu board from the olimex dev board schem
[17:30] <jcoxon> never mind
[17:30] <edmoore> fnoble: exactly my plan
[17:30] <fnoble> what pitch is the cpu?
[17:30] <edmoore> basically check it with all our hardware then produce the board knowing it'll work
[17:30] <edmoore> 0.5 again
[17:30] <fnoble> i mean, lead pitch
[17:30] <edmoore> lqfp208
[17:30] <fnoble> ok, so not too bad
[17:30] <edmoore> nah
[17:30] <fnoble> 208 hehe this will be fun
[17:31] <fnoble> but anything with sticky out leads will yeild to the awesome power of the solder wick technique, its just qfn that gets to be a pain
[17:32] <edmoore> exactly
[17:32] <edmoore> and we have an FPU!!!
[17:32] <fnoble> indeed
[17:32] <edmoore> audio proc heaven
[17:32] <fnoble> no more bitchy fixed point kalman filters
[17:32] <edmoore> or emulated fp
[17:32] <edmoore> at 0.1mph
[17:33] <fnoble> also, i can port the rtty code to anything that has a c compiler now basically
[17:33] <edmoore> exactly
[17:33] <fnoble> i know the code pretty well now and it doesnt have many requirements
[17:33] <edmoore> this board comes preloaded with lunux
[17:33] <edmoore> probably want to loose that
[17:34] <edmoore> but it does mean there'll be lots of pillageable code
[17:34] <fnoble> yeah, i would say so
[17:34] <fnoble> the actual coding cant be any harder than the lpc i imagine
[17:34] <edmoore> ethernet for example might be useful... maybe
[17:34] <edmoore> if we want to use a badger to run a track-a-tron
[17:35] <fnoble> pha, ethernet can get lost
[17:35] <edmoore> i'd put the hardware onto a port
[17:35] <edmoore> though actually an ngw100 may be much better and cheaper for that
[17:35] <edmoore> i wouldn't adevocate having a massive eth connector on badger
[17:35] <fnoble> indeed
[17:36] <fnoble> we really dont need to be able to serve our website from 100kft
[17:36] <edmoore> that would be cool though :)
[17:37] <jcoxon> edmoore, oh dear :-p
[17:37] <edmoore> anyway, we can experiment with it and get all the basic badger stuff working
[17:38] <fnoble> edmoore: the track-o-tron is a project unto itself, we shouldnt let that change badger
[17:38] <jcoxon> so you guys upgrading badger?
[17:39] <jnd> badger badger badger...
[17:39] <fnoble> yeah
[17:39] <fnoble> are we going to make an lpc cpu board then?
[17:39] <fnoble> maybe make some pcbs but only assemble then if we come unstuck on the arm9 design
[17:40] <fnoble> jcoxon: yeah, its going to be more powerful than my last pc
[17:40] <jcoxon> haha!
[17:40] <edmoore> fnoble: i was working with that intention, aye
[17:41] <fnoble> 200 bitchin megahertz
[17:41] <edmoore> so that we basically loose nothing we have now
[17:41] <fnoble> :p
[17:41] <edmoore> 200 bitching floating point ops per u-sec
[17:41] <fnoble> edmoore: yeah, sounds like the best way to proceed
[17:41] <edmoore> well, 184mhz for the industrially rated part
[17:41] <edmoore> but that'll do
[17:42] <edmoore> it also has a 2.5mA low power mode
[17:42] <edmoore> normally it's a fair few mA - but we definitely don't need all that for a balloon, obv
[17:42] <fnoble> yeah, but on a balloon we can afford much more battery power in our weight budget
[17:43] <fnoble> i mean, the lithiums we are using are still like 99% full when it lands
[17:44] <fnoble> edmoore: it also means we can run some pretty sophisticated error correcting codes stuff if we wanted
[17:44] <jnd> make it float for days :)
[17:46] <edmoore> fnoble: exactly
[17:47] <edmoore> so I was thinking maybe 2 radios
[17:47] <edmoore> 1 rtty 50 baud
[17:47] <edmoore> for chasing
[17:47] <edmoore> the other, maybe a 1.2kbps with turbo codes/reed-sol and the dish on trackatron
[17:47] <edmoore> just see how she holds up
[17:48] <fnoble> yeah, we need to find a spot for our dish
[17:48] <fnoble> and maybe source an az-el rotator
[17:49] <fnoble> at least see how expensive they are
[17:49] <fnoble> ideally we would want two independant ones, one with the dish and one with a shortish yagi
[17:52] <edmoore> how about 2 antennas on one tracker?

[19:19] <Hiena> Groan... This SIGIO error makes me crazy...
[19:20] <Hiena> I'll shave some kernel monkey, if it's a kernel bug....
[19:22] <fnoble> Hiena: whats the problem?
[19:25] <Hiena> I'm working an serial to TCP/IP code for linux. The serial handling copy-pasted from the serial programming how-to, so it's a basic vanilla stuff. The code use SIGIO calls for fetching the GPS messages from the serial port. But, after a two hundred something fetch, it's lock up.
[19:26] <Hiena> I went back to the sample code, and it's does the same. And the lock up happens at different conditions, so it couldn't be a memory handling problem.
[19:29] <fnoble> and it needs to be async? you cant just use the serial port like a file?
[19:30] <Hiena> Nope. I want to use as non blocking.
[19:30] <fnoble> yup ok
[19:31] <fnoble> well, you could use blocking calls and put them in a separate thread
[19:31] <fnoble> but yeah, SIGIO should work
[19:31] <Hiena> But seems like, i'll ends up that way...
[19:32] <fnoble> so when you say locks up, what do you mean exactly? is there any error message given?
[19:34] <fnoble> also, can you monitor the process' memory usage as its running, just to make doubly sure there is not a memory leak
[19:36] <jcoxon> crap, i've got a lipo that has inflated
[19:37] <fnoble> jcoxon: hehe
[19:37] <fnoble> jcoxon: overcurrent?
[19:37] <jcoxon> it hasn't been turned on
[19:37] <jcoxon> well not for a while
[19:37] <Hiena> There is a main loop, which is running endless, when SIGIO happens it's flip a bit and the main loop read the port anw writes the output, and flip the bit back.
[19:38] <jcoxon> its pretty solid
[19:38] <jcoxon> the question is - what the hell do i do with it
[19:39] <Hiena> When the "glitch" happens, the code locks in the main loop and nothing happens. Seems like waiting for the next sigio call.
[19:39] <Hiena> jcoxon, do you have a barbeque stove? Put it in and set on fire.
[19:40] <Hiena> It will makes a nice show.
[19:40] <fnoble> jcoxon: is it still holding charge?
[19:40] <fnoble> jcoxon: if so go outside and short it out and watch the show

[20:30] <SpikeUK> A lot earlier today rharrison_ was looking for a source of 2x 3-way IDC connectors suitable for ISP use. The oly place in the UK that I've been able to find these are http://www.toby.co.uk/content/catalogue/products.asp?series=101-W-xx-R1
[20:31] <SpikeUK> ..currently out of stock but I'll be ordering some when they arrive - you are welcome to a few if you can wait!
[20:33] <jcoxon> natrium42, ping
[20:34] <jcoxon> does anyone know if the tracker is GET or POST?
[20:35] <SpikeUK> jcoxon - not me - sorry!
[20:36] <jatkins> jcoxon: used to be a get
[20:36] <jatkins> but I think natrium said he was gonna make it a post
[20:36] <jatkins> http://wiki.ukhas.org.uk/projects:tracker
[20:37] <jatkins> according to that, it's GET
[20:37] <jcoxon> i had afeeling it was still GET

[21:38] <fnoble> edmoore: hello, ok
[21:38] <edmoore> hello
[21:38] <fnoble> edmoore: am doing some work on the mapping/tracking
[21:38] <edmoore> cool
[21:38] <edmoore> tell
[21:38] <fnoble> i may have interesting things to show you soon
[21:39] <edmoore> loading/refresh times?
[21:39] <fnoble> basically ditched gpsdrive
[21:39] <fnoble> but am trying out a replacement thats nicer and much much faster
[21:39] <edmoore> will this be functional for next sunday? they'll def want to see it
[21:39] <fnoble> well, at the least we can go back to what we were using before
[21:40] <fnoble> but yes, i hope it will be
[21:40] <edmoore> cool cool
[21:40] <edmoore> so what's the new software?
[21:40] <fnoble> ill tell you more when i get a bit further
[21:40] <fnoble> want to see how far i can push it first :)
[21:40] <edmoore> ok :)
[21:41] <edmoore> well I don't think I will be making the 9302 package in eagle tonight
[21:41] <fnoble> hehe
[21:41] <edmoore> just frove 2.5 hrs and will catch the end of master& commander and have a beer
[21:41] <edmoore> note the olimex documentation for the board is in LaTex
[21:41] <edmoore> I like these guys.
[21:42] <fnoble> yeah they rock

[21:42] <fnoble> i cant get over how cheap they are, just ordered a batch of pcbs to mount the leds for the torch
[21:42] <edmoore> they are damn good, yes
[21:43] <fnoble> and they did a good job on the torch main pcb assembly
[21:43] <edmoore> oh they did assy too?
[21:43] <edmoore> nice
[21:44] <natrium42> bulgaria ftw?
[21:44] <jcoxon> does any one here use a nokia with s60 on it?
[21:44] <fnoble> edmoore: just to give you a small hint about the mapping, im currently ripping google maps for all of east anglia to use with it
[21:44] <edmoore> fnoble: the one thing where the at91sam9 beats the cirrus is io - it has a lot more peripherals
[21:44] <edmoore> oooh....
[21:45] <edmoore> is this some cunning php ripping ploy?
[21:45] <fnoble> and ive already got all the OSM data loaded in
[21:45] <edmoore> where did you find that?
[21:45] <fnoble> nope, its a feature of the program
[21:45] <fnoble> although your not supposed to bulk download from google maps
[21:46] <fnoble> but its only a small amount of data really
[21:46] <edmoore> their servers can take it
[21:46] <fuzzylugnuts> yeah
[21:46] <fnoble> anyway, it has some flaws that make it unsuitable for us atm
[21:47] <fnoble> but am going to try and mod it
[21:47] <edmoore> awesome
[21:47] <edmoore> this is all exciting
[21:47] <edmoore> you know theres a big parabolic dish in the little coffee room thing up the stairs from the autoclave room?~
[21:47] <fnoble> yup
[21:47] <edmoore> wonder if they want it
[21:48] <fnoble> indeed
[21:48] <fnoble> although it cant be too expensive to get hold of an old sat tv dish
[21:49] <edmoore> sure
[21:50] <fnoble> we should tripod mount our yagi for sunday
[21:50] <edmoore> def
[21:50] <fnoble> is the flight actually going to be then? whats the weather like?
[21:50] <edmoore> too early to tell
[21:50] <fuzzylugnuts> fnoble: do you have an "arrow antenna" ?
[21:51] <edmoore> we're going to confirm thursday afternoon
[21:51] <fnoble> arrow antenna?
[21:51] <edmoore> yeah i was reading about arrows
[21:51] <fuzzylugnuts> its a collapsible yagi
[21:51] <fuzzylugnuts> I have one.... I just asked because there is a hole under the handle that is 1/4-20, tripod threading. it mounts easy
[21:52] <fnoble> ah, no we dont have one like that
[21:52] <fuzzylugnuts> ah, ok
[21:52] <fnoble> im not sure where ours came from
[21:52] <fuzzylugnuts> ok
[21:52] <edmoore> i'm not sure ours is any good
[21:52] <edmoore> infact I'm faqirly sure it isn't
[21:52] <fuzzylugnuts> hmm
[21:52] <fnoble> well it works
[21:53] <fuzzylugnuts> you pretty much stay around 70cm?
[21:53] <fnoble> but yes its not hogh quality
[21:53] <edmoore> you can't fault it for working, no
[21:53] <edmoore> but work is a scalar db value
[21:53] <fnoble> yeah, we only have a 70cm reciever
[21:53] <fuzzylugnuts> ok
[21:53] <fuzzylugnuts> I bet you'd love the arrow.
[21:53] <fnoble> so we are more fixed by that than anything else
[21:54] <fuzzylugnuts> alright
[21:54] <edmoore> for that length (the parcel shelf of my car) I reckon we could get more gain. But it's not really necessary for what we do - it all works so far
[21:54] <fuzzylugnuts> ok
[21:55] <edmoore> and we drive with the whip so that's really the limitng factor
[21:55] <fnoble> yeah it is quite a long one
[21:55] <fnoble> we should make a 1/2 wave whip for the car
[21:55] <fnoble> should help a bit
[21:55] <edmoore> fo show
[21:56] <fnoble> although whips have a dead point directly up as im sure you know, hence why when its right above us things arent so good
[21:56] <fnoble> btw, did our handheld gps ever materialise?
[21:56] <edmoore> yes
[21:56] <edmoore> i have it
[21:56] <edmoore> the tx also has a dead point directly below it
[21:56] <fnoble> did it come with the serial cable?
[21:56] <edmoore> so we're really screwed :)
[21:56] <edmoore> no
[21:57] <fnoble> edmoore: yup
[21:57] <edmoore> no serial cable - why do you want one?
[21:57] <fnoble> edmoore: we'll just have to be a bit less cocky about following it then
[21:57] <fnoble> edmoore: so we can use it to show the car's pos when we are chasing
[21:57] <edmoore> we have that in the for of the gps in the roof box
[21:58] <fnoble> ?
[21:58] <edmoore> we've built a roof box
[21:58] <fnoble> oh ok
[21:58] <edmoore> a lever system to attach and detach it
[21:58] <fnoble> just the box, or the contents too?
[21:58] <edmoore> pretty cnc'd streamlined shape
[21:59] <fnoble> cool
[21:59] <edmoore> and a usb hub in it
[21:59] <fnoble> what out of
[21:59] <edmoore> just acrylic
[21:59] <fnoble> ok
[21:59] <edmoore> but it's transparent
[21:59] <edmoore> looks cool
[21:59] <fnoble> ok
[21:59] <fnoble> does it have an antenna mounting point?
[22:00] <edmoore> we have to drill some holes for that - didn't have the antenna to measure from at the time :)
[22:00] <jcoxon> fnoble, you use python don't you?
[22:00] <edmoore> probs just use one of those chassis mount bnc
[22:02] <fnoble> jcoxon: yes, but im not all that good at it
[22:04] <edmoore> he is being coy
[22:05] <jcoxon> :-)
[22:05] <jcoxon> edmoore, what phone do you have?
[22:05] <edmoore> k910
[22:05] <edmoore> or soemthing
[22:05] <edmoore> and a 6310... but it's on the payload
[22:06] <jcoxon> cause i've pretty much got an autotrack script working on my phone
[22:06] <jcoxon> to upload its gps position to the tracker over gprs
[22:10] <fuzzylugnuts> bbl, going to hot-air balloon festival
[22:13] <edmoore> fnoble: if we could get a dish, this would do us http://polysat.calpoly.edu/earthstation/equipment/hertz-antennas-large.jpg
[22:14] <edmoore> a stacked pair of, say, 8 wavelength yagis
[22:14] <edmoore> and some bricks :)
[22:14] <fnoble> hehe
[22:15] <fnoble> well, the amateur radio astronomy guys have restored partially one of the old radio telescopes up near the cavendish
[22:15] <fnoble> they have got it recieving on 70cm band
[22:15] <rocketboy> ideal
[22:15] <edmoore> likewise a chap on #fpga
[22:15] <edmoore> the restored one in holland
[22:16] <fnoble> 18m dish should do us
[22:16] <edmoore> could crack 300bps
[22:16] <edmoore> with 18m of dish
[22:17] <fnoble> i think its quite slow moving though
[22:17] <rocketboy> 2.4gHz TV
[22:17] <rocketboy> with that size dish
[22:18] <edmoore> this is what this guy on #fpga was restoring http://en.wikipedia.org/wiki/Dwingeloo_Radio_Observatory
[22:19] <fnoble> thats cool
[22:19] <fnoble> think he would actually be willing to use it to listen in on one of our launches?
[22:20] <edmoore> he said he might try :)

[23:01] <edmoore> Laurenceb_: hi
[23:02] <Laurenceb_> I'm still trying to get a bootloader running again :(
[23:03] <Laurenceb_> been very busy lately
[23:04] <Laurenceb_> its rather demoralising that something this simple just will not work
[23:05] <edmoore> it's electronics
[23:06] <edmoore> when you conquer it, all will be well
[23:09] <Laurenceb_> I might try this: http://gandalf.arubi.uni-kl.de/avr_projects/#avrprog_boot
[23:10] <Laurenceb_> it looks kind of cool, but I dont quite understand the wait condition
[23:12] <edmoore> so it looks like you can just hit a key in hyperterm in the first 0.9 secs to make it bootload
[23:12] <edmoore> otherwise it'll just start the program that exists already
[23:14] <Laurenceb_> yeah
[23:14] <Laurenceb_> thats how I read it, which is a pain :P
[23:15] <Laurenceb_> ideally you could just fire up a AVR911 copatible programmer and get on with it
[23:16] <Laurenceb_> oh well, I'll try that if I really cant make any headway
[23:16] <Laurenceb_> when does your term start?
[23:17] <edmoore> 9th
[23:17] <edmoore> though am there from 2nd
