[17:36] <edmoore> afternoon all
[17:36] <natrium42> hey ed
[17:36] <natrium42> i just pointed yet another person to this channel :)
[17:36] <natrium42> wants to launch in the UK and is worried about landing in water
[17:41] <edmoore> haha
[17:41] <edmoore> have they popped up yet?
[17:41] <natrium42> no, i just sent an email response a few mins ago
[17:42] <edmoore> awesome to have another, though
[17:43] <edmoore> I've just been writing the landing spot prediction for the badger board
[17:43] <edmoore> as it happens
[17:43] <natrium42> cool
[17:48] <edmoore> not long to mars!
[17:48] <natrium42> yep :)
[17:48] <edmoore> my evening's telly watching is very thoroughly planned out
[17:48] <edmoore> this evening: peep show and a beer
[17:48] <edmoore> tomorrow, eurovision song contest, and a coupla beers
[17:48] <edmoore> sunday, mars all evening, many beers
[17:48] <natrium42> XD
[17:49] <edmoore> that youtube link would be worth a view if you get 2 hours before sunday
[17:51] <natrium42> yah, i will have some time today

[18:46] <jcoxon> wooohoooo, fast internet access
[18:49] <edmoore> yo
[18:49] <edmoore> how goes it jcoxon ?
[18:49] <jcoxon> good thanks
[18:49] <jcoxon> just got back to london
[18:49] <edmoore> cool
[18:50] <jcoxon> might be popping up to cambridge on sunday evening
[18:50] <jcoxon> not sure yet
[18:50] <edmoore> coool
[18:50] <edmoore> for the landing?
[18:51] <jcoxon> nah for a bday party
[18:51] <jcoxon> but might be around and about
[18:51] <edmoore> :o
[18:51] <jcoxon> what time do they predict the landing in GMT+1?

[19:38] <Laurenceb> hi all
[19:39] Action: Laurenceb just installed hardy
[19:45] <edmoore> hi Laurenceb
[19:46] <edmoore> what is hardy?
[19:46] <Laurenceb> ubuntu 8.04
[19:46] <Laurenceb> firefox 3 is pretty cool
[19:46] <edmoore> oh sorry i totally misread that as 'i just nailed hardy' meaning you'd done well in an exam on hardy
[19:46] <Laurenceb> haha
[19:46] <Laurenceb> :P
[19:46] <edmoore> i've really liked xubuntu since fergusnoble put it on his eee
[19:47] <Laurenceb> I have a machine running xfce at home
[19:47] <Laurenceb> it not bad
[19:47] <Laurenceb> *it's
[19:48] <Laurenceb> but it still wont hybernate, show a bootup screen, turn off, or load without hanging for 5 minutes
[19:49] Akadecca (n=akawaka@external.treyarch.com) joined #highaltitude.
[19:49] <Laurenceb> so you have to "turn it off" by ripping the power cable out the back
[19:50] akawaka (n=akawaka@cpe-76-90-109-68.socal.res.rr.com) left irc: Nick collision from services.
[19:50] Nick change: Akadecca -> akawaka
[19:50] <edmoore> lol
[19:50] <edmoore> technical
[19:50] <edmoore> there's a xubuntu floating around quite tailored to the eee
[19:50] <Laurenceb> I've heard its possible to getting it running perfectly on this machine, just a matter of reading all the forum posts ect
[19:50] <edmoore> if I get one (if only) then I'd probably stick that on it
[19:51] <Laurenceb> I need more RAM :(
[19:52] <akawaka> i was thinking of getting one of the OLPCs
[19:52] <akawaka> they are pretty much giving them away if you want to write some software for them
[19:52] <Laurenceb> the keyboard looks pretty poor
[19:52] <akawaka> the whole thing is very cheap
[19:53] <akawaka> but i guess thats the point
[19:53] <Laurenceb> well tooking at it it seems to be made for durability
[19:53] <akawaka> hmmm, i'd really to start using atmel microcontrollers
[19:53] <Laurenceb> rather than super ease of use - the keyboard that is
[19:54] <Laurenceb> its not too hard
[19:54] <akawaka> their selection is very limited compared to microchip though
[19:54] <Laurenceb> yes, but its not really a problem
[19:54] <Laurenceb> makes it easy to choose :P
[19:55] <Laurenceb> its a pity theres not more USB ones, but its a pain to program
[19:55] <akawaka> you know, thats actually a good point
[19:55] <Laurenceb> and XMEGA is coming out now
[19:55] <akawaka> i never end up getting the same pic, i always end up with a bunch of different ones that are almost the same but not quiet
[19:56] <Laurenceb> give me an FTDI chip and uart any day
[19:56] <Laurenceb> having said that if you have a driven for onboard usb to make it appear as a serial port, thats good
[19:57] <akawaka> ah, the ATtiny looks more like what i'm used to
[19:57] <Laurenceb> I got that running on the AP7000 (NGW100 processor)
[19:57] <Laurenceb> so you can log in over usb - it appears as a serial port on the host system
[19:58] <Laurenceb> have you seen the AP7000 lane change warning device video on youtube?
[19:59] <Laurenceb> its pretty sweet
[19:59] <akawaka> ?
[20:00] <Laurenceb> I'll find it
[20:00] <Laurenceb> oh dear... firefox 3 has crashed
[20:00] <Hiena> As usually.
[20:00] <Laurenceb> and no flash :-(
[20:01] <Hiena> Yup.
[20:01] <Laurenceb> http://www.youtube.com/watch?v=MKyB15KwMyg
[20:05] <Laurenceb> akawaka: what os do you run?
[20:06] <akawaka> xp and linux
[20:06] flowolf (n=flowolf@unaffiliated/flowolf) left irc: "Leaving"
[20:07] <Laurenceb> ok, if you want dirt simple, install avr studio
[20:07] <Laurenceb> under xp
[20:08] <Laurenceb> otherwise install the "avr-pack" or whatever (its called something like that in the ubuntu repository)
[20:09] <Laurenceb> then get a makefile off the net and use emacs or something to write your projects
[20:10] <Laurenceb> quite easy either way, depends what you like to use - I found avr-studio a pain to use sometimes, its glitchy. If you know what your doing just use linux
[20:13] <Laurenceb> ATtiny is crap
[20:13] edmoore (n=edmoore@chu-gw.churchillcambridge.co.uk) left irc:
[20:13] <Laurenceb> the ATmega core is much faster, especially with floating point
[20:17] <akawaka> Laurenceb: not really what i need
[20:17] <Laurenceb> fair enough
[20:17] <akawaka> i'm looking for something pic-like, but with a cleaner architecture
[20:17] <akawaka> more C friendly
[20:17] <akawaka> Pic C tools are shit-ish
[20:18] <Laurenceb> yes
[20:18] <Laurenceb> don't pics need high voltage for programming?
[20:19] <Laurenceb> I know there is in system programming, but does it use >5V or Vcc ?
[20:20] <akawaka> usually one pin needs to be pulled higer than Vcc i think
[20:21] <akawaka> a lot don't support self write either
[20:22] <Laurenceb> bah
[20:22] <akawaka> but i like their small packages and low pin count
[20:22] <akawaka> and how sturdy they are
[20:23] <Laurenceb> yes
[20:23] <Laurenceb> I've fired a couple of avrs
[20:24] <Laurenceb> admittedly one was wired up to 12v and the other had a bunch of pins shorted giving visible sparks
[20:24] <Laurenceb> the annoying thing with avrs is they are vitually impossible to kill completely
[20:25] <akawaka> so they just start acting wreird
[20:25] <akawaka> ?
[20:25] <Laurenceb> you just fry some registers/sram or something, and it carries on limping through the code
[20:25] <Laurenceb> going more and more deranged
[20:25] <akawaka> you and the chip
[20:26] <Laurenceb> its very annoying, at least it it just dies you know whats happening
[20:26] <akawaka> why are pfets so much more difficult to find than nfets?
[20:26] <Laurenceb> lower numbers used?
[20:29] <akawaka> damnit
[20:29] <akawaka> antennas are such a black art
[20:30] <akawaka> all this shit is kept secret so you gotta buy amateur radio books
[20:33] <Laurenceb> grr ed has gone
[20:35] <Laurenceb> got charged customs :-(
[20:36] <akawaka> sparkfun?
[20:36] <Laurenceb> yes
[20:37] <akawaka> sucks
[20:37] <akawaka> like i said, feel free to shit that stuff to me and i can open it up and send it on to you
[20:37] <Laurenceb> :P
[20:38] <Laurenceb> how will that help?
[20:38] <Laurenceb> they "value" the goods at customs using sparkfuns form?
[20:38] <akawaka> dunno
[20:38] <akawaka> but maybe if it looks like someone sending someone else a package they won't charge customs
[20:39] <Laurenceb> hmm maybe
[20:39] <akawaka> but you order from spark fun, the box is gonna have an invoice and look bought
[20:39] <akawaka> not sure, maybe they just fuck you both ways
[20:39] <Laurenceb> I've bought stuff from china and its been packaged like a "personal gift"
[20:39] <Laurenceb> so maybe it does help
[20:40] <Laurenceb> lable was hadwritten and had some random guys name on :P

[21:05] <Laurenceb> hmm whats sqrt(i) ?
[21:05] <Laurenceb> doesnt exist does it?
[21:11] <akawaka> 0.707 + 0.707i according to google
