[00:00] <rjharrison> I'd like to think that i would limit myself to the commercial modules. There are some which you can change the crystal on
[00:00] <edmoore> if you could use 14mhz over here, it'd be super tempting to build something
[00:00] <rjharrison> I'm still going to do a rtty and cw test beacon
[00:01] <edmoore> that's easily within the range of £5 DDSs
[00:02] <akawaka> 10mhz was fun to build
[00:02] <akawaka> though to be honest, rf is a pain in the ass to work with
[00:05] <rjharrison> edmoore did you solder the connector to badger for the IQ
[00:05] <edmoore> yep
[00:05] <rjharrison> That was good going as the pins are bloody small on there
[00:06] <rjharrison> do you know what the pitch is
[00:06] <edmoore> pah, that was easy
[00:06] <edmoore> they're quite big
[00:06] <edmoore> you wanna try the telit module connector
[00:06] <edmoore> that took some concentration
[00:08] <edmoore> http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=101
[00:08] <edmoore> the long thin white thing at the bottom
[00:09] <rjharrison> Nasty
[00:10] <rjharrison> That's why I paid 16 bucks for the breakout
[00:10] <edmoore> a good iron is a good investment, though
[00:10] <edmoore> that makes it quite easy
[00:10] <edmoore> that and lots of flux
[00:10] <rjharrison> Not my 15 quid one from maplins then
[00:10] <edmoore> you may aswell use it to stab your eye for all the good it'll do
[00:10] <rjharrison> Hey I built icarus
[00:10] <edmoore> it's worth getting a good one
[00:10] <rjharrison> it
[00:10] <rjharrison> Any hints
[00:10] <edmoore> icarus is mainly through hole isn't it?
[00:11] <rjharrison> Yep :)
[00:11] <edmoore> there you go :p
[00:11] <edmoore> smd is a different beast
[00:11] <edmoore> the lassen connector is at the large end of smd - *but*, as I say, a decent iron helps a lot
[00:11] <rjharrison> Surface mount is the way of the future?
[00:11] <edmoore> since about 1970 yeah
[00:12] <rjharrison> hehe
[00:12] <rjharrison> Hey I'm getting there
[00:12] <edmoore> you are blasting through the learning curve, tis true
[00:12] <rjharrison> that was a year befor even I was born
[00:12] <edmoore> 17 years before me
[00:13] <rjharrison> Bugger off
[00:13] <rjharrison> :P
[00:13] <edmoore> :p
[00:16] <rjharrison> I have ordered the whole IQ set from dpie ready for the beacon launch
[00:16] <edmoore> kd7lmo.net is like balloon porn
[00:18] <rjharrison> Fuck me that is one hell of a payload train
[00:18] <akawaka> the software defined tracker payload is pretty awesome
[00:18] <rjharrison> imagin droping that into peterborough
[00:19] <rjharrison> It's past the witching hour. I'm off to bed
[00:19] <edmoore> cool, cya
[00:19] <rjharrison> chat tomorrow

[00:24] <akawaka> http://kd7lmo.net/hf-aprs.html
[00:25] <akawaka> is it difficult to design a circuit that can work across such a large frequency range?
[00:25] <gordonjcp> akawaka: how wide a frequency range?
[00:26] <akawaka> that circuit seems to be able to output rf from 3mhs to 144mhz
[00:27] <gordonjcp> continuously, or in bands?
[00:27] <akawaka> looks like it runs in bANDS
[00:27] <edmoore> it uses a dds but it's quite cunning
[00:27] <gordonjcp> oh
[00:27] Action: gordonjcp looks at the link
[00:27] <akawaka> it has two separate output stages too
[00:27] <akawaka> one for hf and one for vhf
[00:27] <edmoore> it generates freqs about the dds rating by mixing it with a low freq signal and using one of the higher freq images
[00:27] <gordonjcp> well the HF and VHF stuff will be separate
[00:32] <akawaka> this guy is a pro
[00:34] <edmoore> yep
[00:36] <akawaka> probably a lot easier to build a radio these days with modules like DDS, linear amps, etc
[00:36] <akawaka> rather than a bunch of discreet parts

[19:16] <jcoxon> natrium42, any idea why on my tracker there is a line back to the start point?
[19:48] <natrium42> hmm
[19:48] <natrium42> jcoxon, check your database
[19:50] <jcoxon> what am i looking for?
[19:51] <jcoxon> the position ids are in order
[19:51] <jcoxon> not sure why it links back to the start
[20:00] <natrium42> are there any duplicates?
[20:01] <jcoxon> no
[20:01] <jcoxon> do you want access?
[20:01] <jcoxon> would that help?
[20:02] <natrium42> i can look at JSON first
[20:02] <natrium42> just need to pack a few shipments, sorry

[20:57] <natrium42> jcoxon, what's the url to your tracker again?
[20:58] <natrium42> nvm
[21:00] <jcoxon> ?
[21:00] <jcoxon> find it?
[21:00] <jcoxon> i think it might be an old copy of your tracker
[21:01] <jcoxon> which i adapted to accept POST
[21:01] <natrium42> yeah
[21:01] <natrium42> it seems to ignore position_id in the GET request
[21:01] <natrium42> for example
[21:02] <natrium42> http://www.pegasushabproject.org.uk/track/data.php?format=json&position_id=128
[21:02] <natrium42> returns all the positions
[21:02] <natrium42> instead of positions starting from 128
[21:02] <jcoxon> hmmmm
[21:03] <jcoxon> could i upgrade it to the lastest version yet maintain the database?
[21:03] <natrium42> yep
[21:03] <jcoxon> just reinstall it then?
[21:03] <natrium42> should do, yes
[21:03] <natrium42> just keep your config file
[21:04] <natrium42> only data.php is buggy, really
[21:04] <natrium42> so you can overwrite it
[21:04] <jcoxon> and to make it POST?
[21:04] <natrium42> oh
[21:06] <natrium42> just do
[21:06] <natrium42> $vars = array_merge($HTTP_GET_VARS, $HTTP_POST_VARS);
[21:07] <natrium42> then replace all instances of $HTTP_GET_VARS with $vars
[21:07] <jcoxon> in data.php?
[21:07] <natrium42> yep
[21:08] <akawaka> $_REQUEST
[21:10] <natrium42> hmm, good point
[21:10] <natrium42> so just replace all $HTTP_GET_VARS with $_REQUEST
[21:10] <akawaka> $HTTP_GET_VARS is so 2005!!!!eleven
[21:11] <natrium42> i thought $_REQUET was deprecated along with $_GET and $_POST
[21:11] <natrium42> :P
[21:11] <natrium42> superglobals are apparently evil

[21:52] <edmoore> was wondering about that
[21:52] <jcoxon> hey edmoore
[21:52] <jcoxon> yeah
[21:52] <edmoore> they should be, by rights
[21:53] <jcoxon> indeed
[21:53] <edmoore> thought it was after chrimbo last year, iirc
[21:53] <jcoxon> nothing on their site
[21:53] <jcoxon> yeah that does ring a bel
[21:53] <jcoxon> bell*
[21:55] <jcoxon> the first launch was dec 2007 somtime
[21:59] <akawaka> so next years Leonid meteor shower is predicted to be a big one
[21:59] <akawaka> would be interesting to launch a balloon during it
[21:59] <edmoore> or northern lights, as jcoxon pointed out
[22:00] <edmoore> or... a storm!
[22:00] Action: jcoxon is on a fact finding mission concerning balloons and the northern lights
[22:00] <edmoore> elaborate
[22:00] <edmoore> dh: ping
[22:00] <jcoxon> this is where i am:
[22:00] <jcoxon> http://www.pegasushabproject.org.uk/track/
[22:01] <jcoxon> akawaka, i think there has been an amateur balloon and a meteor shower before with aerogel
[22:02] <jcoxon> akawaka, http://science.nasa.gov/newhome/headlines/ast18nov98_1.htm
[22:03] <jcoxon> but we could do that!
[22:03] <edmoore> jcoxon: what are you doing so far north?
[22:03] <edmoore> I am building a high alt telescope
[22:03] <jcoxon> going to see the northern lights!
[22:04] <jcoxon> i'm going further north tomorrow
[22:04] <edmoore> we could eaily whack a wide angle lens on and point it at a large patch of sky for 5 mins at a time
[22:04] <edmoore> what's the temp like?
[22:04] <jcoxon> it isn't that bad right now
[22:04] <jcoxon> above 0
[22:05] <jcoxon> narvik is kept warmer by teh sea
[22:05] <jcoxon> that said the ice on the roads is deadly, nearly fell over
[22:05] <edmoore> eek
[22:06] <jcoxon> its a bit cloudy, hopefully by the time we get to tromso it'll clear a bit
[22:06] <jcoxon> and we'll get to see the sky
[22:06] <jcoxon> i've fixed teh code on my phone to update my tracker with my whereabouts
[22:10] <edmoore> how do you scrpt for your iphone jcoxon ?
[22:10] <jcoxon> i don't
[22:10] <jcoxon> i use python on my nokia
[22:10] <edmoore> ah kk
[22:10] <jcoxon> its nice as it runs in the background
[22:10] <jcoxon> unlike the stupid iphone

[22:28] <rjharrison> For distance test. Proably 50
[22:29] <rjharrison> I think slower = further!
[22:30] <edmoore> anyone, on the off chance, know where you can get a proper cheese wire/board thing for cutting decent bits of cheese?

[23:56] <edmoore> mini 9
[23:56] <edmoore> can run osx
[23:57] <RocketBoy> its a tough choice
[23:57] <edmoore> all the netbooks have identical specs
[23:58] <SpeedEvil> well - no
[23:58] <edmoore> microsoft set the limits of the hardware they'll allow xp to be run on for the price they sell it
[23:58] <SpeedEvil> they vary from ~8-10" screen, and significantly on battery life
[23:58] <edmoore> part of their 'oh shit, linux could take over' response
[23:58] <SpeedEvil> And some don't come with XP
[23:58] <edmoore> have a look at the linux vs time for netbooks, SpeedEvil
[23:58] <edmoore> it's plummeted
[23:59] <SpeedEvil> Yeah :/
[23:59] <edmoore> they're just responding to demand - and that's overwhelmingly for xp
[23:59] <edmoore> and that version of xm home is sold on the basis of... max 10" screen, 1.6ghz atom, 1gb ram etc etc
[23:59] <SpeedEvil> I do wonder how much some of the netbook companies have put into OS development
