[00:36] <Tiger^> ok, i'm launching at 09:00 UTC.
[00:36] <Tiger^> everything's ready :)
[00:52] <defy> awesome :D

[12:10] <phatmonkey> I have some questions about the robostix. is there any software installed on it already? i just want to read values from analogue inputs and control servos and GPIOs from the gumstix. how does the gumstix communicate with the robostix? i2c? i want two serial ports for devices, but how do i then communicate with the gumstix, there seems to be no spare serial ports or a USB port
[12:10] <phatmonkey> dammit
[12:10] <phatmonkey> wrong channelk
[12:10] <phatmonkey> dum dee dum
[12:11] <defy> hehe :)
[12:11] <defy> im fighting with my robostix also
[12:17] <phatmonkey> the robostix looks perfect, but there's very little information on it on gumstix.com or gumstix.org
[12:17] <phatmonkey> ... or maybe i'm just an idiot
[12:17] <phatmonkey> probably the latter
[12:24] <defy> lol
[12:24] <defy> if its just a gumstix/robostix combo, its pretty straight forward
[12:25] <defy> start with... http://www.gumstix.org/tikiwiki/tiki-index.php?page=Robostix-Gumstix-ISP
[12:25] <defy> to get uisp working
[12:26] <defy> then, http://www.gumstix.org/tikiwiki/tiki-index.php?page=Robostix-i2c-BootLoader to get the i2c bootloader on there
[12:26] <defy> and http://www.gumstix.org/tikiwiki/tiki-index.php?page=I2CQuickstart if you havent gotten i2c on the gumstix working yet..
[12:27] <defy> http://www.gumstix.org/tikiwiki/tiki-index.php?page=Robostix-i2c-load for loading programs onto the robostix via i2c
[12:28] <defy> and then finally, http://www.gumstix.org/tikiwiki/tiki-index.php?page=Robostix-i2c-io for i2c-io, which lets you read the adc's, control the pwm's and so on
[12:31] <defy> if you're not using a console port on the robostix you'll also need to jumper pins 3 and 4 of the 'gumstix' plug with a 10k resister while the gumstix and robostix are connected
[13:02] <phatmonkey> ah nice
[13:02] <phatmonkey> thanks
[13:02] <phatmonkey> defy, can I use the two gumstix serial ports for devices?
[13:03] <phatmonkey> if i do, how do i communicate with the gumstix?
[13:04] <defy> from the robostix you mean?
[13:06] <phatmonkey> no, from another computer
[13:06] <phatmonkey> well, can I disable the serial console so I have 2 serial ports?
[13:06] <defy> I believe so
[13:07] <phatmonkey> how would I communicate with the gumstix then
[13:07] <defy> i think it depends on what board you're connecting to the gumstix
[13:07] <phatmonkey> with no serial console or usb networking
[13:07] <defy> are you just wanting to console the gumstix, with no robostix or anything?
[13:07] <defy> well, if you disabled the console, you wouldn't...youd need some form of communication
[13:08] <phatmonkey> i have gumstix and robostix together, the two TTL serial ports used on the robostix
[13:08] <phatmonkey> how would I then communicate with the gumstix?
[13:08] <phatmonkey> can I add a usb port somehow? or maybe another serial port
[13:09] <defy> possibly one of the other breakout boards which uses the 90pin hirose
[13:10] <defy> might give you access to the other serial ports
[13:10] <defy> I'm not entirely sure
[13:10] <phatmonkey> ah, true
[13:10] <defy> I just connected mt gumstix/gpsstix combo to my robostix via 2 cables though
[13:10] <defy> and got i2c-io working
[13:10] <phatmonkey> i'll ask on the mailing list
[13:11] <defy> yea they're always quite helpful
[13:11] <defy> you weren't wanting to add network or anything? a netcf/mmc card would let you plug it into a network while using those two serial ports
[13:22] <phatmonkey> hmm, we'll see
[13:22] <defy> What sensors are you planning on using>?
[13:23] <phatmonkey> IR thermopiles
[13:24] <phatmonkey> temperature sensors and other goodies later
[13:24] <defy> cool, I'm waiting on 2 of those two arrive
[13:24] <defy> I'm going to try combine them with some rotation rate sensing gyros
[13:24] <phatmonkey> might consider pressure sensors for correcting altitude and working out real airspeed
[13:24] <phatmonkey> ah yes
[13:25] <defy> been waiting almost a month now, i should have just gotten the kits
[13:26] <phatmonkey> yikes
[13:29] <phatmonkey> hmms, wonder if i have a ttl -> rs-232 convertor anywhere
[13:29] <phatmonkey> i'll need it for http://www.gumstix.org/tikiwiki/tiki-index.php?page=Robostix-Gumstix-ISP won't I
[13:30] <defy> if you want to console into it yeah
[13:30] <defy> otherwise you need the resister between pins 3 and 4
[13:31] <phatmonkey> http://www.gumstix.org/tikiwiki/tiki-index.php?page=Robostix-Gumstix-ISP - i'm not completely clear. is that flashing the robostix so I can use the gumstix to upload stuff to it?
[13:32] <defy> I dont think you need to reflash anything
[13:33] <defy> just load the robostix module
[13:33] <defy> and unzip all the other files into your filesystem
[13:33] <phatmonkey> urm
[13:34] <phatmonkey> http://www.gumstix.org/tikiwiki/tiki-index.php?page=Robostix-Gumstix-ISP - so what are we doing there?
[13:34] <phatmonkey> setting up the gumstix to flash the robostix?
[13:34] <defy> its not a flash, as much as a software upload
[13:34] <phatmonkey> well, to upload stuff to the robostix flash
[13:34] <defy> you're not replacing uboot or anything
[13:34] <phatmonkey> yes
[13:34] <defy> yea, exactly
[13:35] <phatmonkey> ok
[13:35] <defy> what I did, which might differ from what you want to do, was just put the i2c boot loader into the robostix
[13:35] <defy> and then use i2c-io to get/set any of the values i wanted from the gumstix
[13:36] <defy> if you're writing all of your code for the atmega you shouldnt have to worry about that stuff
[13:36] <defy> are you wanting to read the sensors and control the pwm's from the gumstix its self? or from the robostix?
[13:36] <phatmonkey> I understand now, that's what I want to do
[13:37] <phatmonkey> yes, i'm doing everything from the gumstix
[13:37] <defy> cool
[13:38] <defy> the only downside is that the i2c is much slower, with my gyros and the ADC ports i get about 20 polls a second, where if i used the robostix directly i would get closer to 200
[13:38] <defy> but i still think 20 is fine
[13:38] <defy> even 5 would be okay, and it makes things much easier, I'm just using microperl and shell script for all of the control stuff, saves having to write it all in C
[13:39] <phatmonkey> yeah, i'm writing some of the critical realtime stuff in C
[13:39] <phatmonkey> the rest in threaded perl
[13:39] <defy> sweet
[13:40] <phatmonkey> correction, I'm getting somebody else to write the C stuff
[13:40] <phatmonkey> my 10 year old "C for dummies" is collecting dust
[13:40] <phatmonkey> hehe
[13:41] <defy> hehe
[13:43] <phatmonkey> the nokia 5110 isn't too heavy I guess
[13:44] <phatmonkey> I could leave the ring on full volume, and we can call it to help locate the payload..>!
[13:44] <defy> hehe sweet
[13:44] <phatmonkey> would save trying to hook up something noisy to the robostix
[13:45] <phatmonkey> might still try hook up something flashy too
[13:45] <phatmonkey> knowing my coding, it's bound to miss the landing point sometimes
[13:46] <defy> http://defy.net/balloon/images/gumstix-i2c-robo.jpg just took that after finally getting the i2c working
[13:47] <phatmonkey> ah niice
[13:48] <phatmonkey> I spy a radio... are you from the uk?
[13:48] <defy> nah, nz
[13:48] <phatmonkey> ah right
[13:48] <defy> I'm using that to shell into the gumstix
[13:51] <phatmonkey> what sort of airframe are you thinking of using?
[13:51] <phatmonkey> the parafoil?
[13:52] <defy> probably just a balsa/monocoat glider to start with
[13:54] <phatmonkey> ah, ka
[13:54] <phatmonkey> y
[13:54] <defy> parafoil still could be a possability with a very stiff frame
[13:54] <defy> but I'm not sure how much effort i want to put into that idea
[13:55] <phatmonkey> yeah, i rejected parafoils just because they get tangled terribly easily
[13:55] <phatmonkey> a stable plane woul dbe easier to control too
[13:59] <defy> are you making it powered?
[14:00] <defy> the plane i mean, or a glider?
[14:00] <phatmonkey> well i'm using a powered plane for developing the autopilot
[14:00] <phatmonkey> but the finalk thing is just going to be a glider
[14:01] <defy> cool
[14:02] <defy> I've just about finished a gps guided boat which I'll use in the harbour outside to help build the 2d part of the navigation software...its winter time here so there wont be any good flying weather for another 4-5 months
[14:02] <defy> had to find something else to do to pass the time, heh
[14:03] <phatmonkey> ah yeah
[14:03] <phatmonkey> my exams end in under a week, then i've got holidays until september
[14:03] <phatmonkey> it would be nice to get something fully working by then
[14:03] <defy> cool
[14:03] <defy> should be doable
[14:04] <defy> have you ever been to rcgroups.com? they have quite a good uav forum
[14:04] <phatmonkey> yep, i've got a few threads there
[14:04] <defy> oh nice :)
[14:04] <phatmonkey> most have been hijacked by people thinking i'm a terrorist though
[14:04] <phatmonkey> and people reminding me that i'm going to kill people/damage things/destroy the world
[14:04] <defy> hah really? thats typical of a web forum

[17:36] <jcoxon> whats all the yaying about?
[17:39] <Tiger^> hehe
[17:39] <Tiger^> the flight was successful
[17:40] <Tiger^> :)
[17:41] <defy> nice :)
[17:41] <jcoxon> amazing Tiger^
[17:41] <jcoxon> the phone worked!
[17:41] <jcoxon> tell all...
[17:42] <Tiger^> yeah
[17:42] <Tiger^> i'll tell everything
[17:42] <Tiger^> but we got sunburned bad
[17:42] <Tiger^> + burns from nettles
[17:42] <jcoxon> ouch
[17:43] <Tiger^> yeah
[17:43] <Tiger^> the phone worked, we recovered the payload
[17:43] <Tiger^> the gps had 10 sats, so we found it where it should be.
[17:44] <Tiger^> the photos are great :)
[17:44] <jcoxon> :-D
[17:44] <jcoxon> is there a chance you could upload them?
[17:44] <jcoxon> i'm so glad it all worked!
[17:45] <defy> yea Tiger^ nice work, cant wait to see photos :D
[17:45] <Tiger^> i'll put the photos up in a moment
[17:47] <phatmonkey> Tiger^, oh NICE!
[17:47] <phatmonkey> :D
[17:48] <phatmonkey> we need to make a page on the ukhas site for each launch...
[17:48] <jcoxon> nice idea phatmonkey
[17:48] <phatmonkey> and get all these piccies in the flickr pool
[17:48] <jcoxon> just a few details, e.g. payload weight, balloon type
[17:48] <phatmonkey> and a story?
[17:48] <jcoxon> yeah
[17:49] <jcoxon> i reckon i'll be launching on the weekend
[17:49] <phatmonkey> explaining what's in it and how the flight went
[17:49] <jcoxon> if the weather sorts itself out
[17:49] <phatmonkey> nice
[17:49] <phatmonkey> i will probably get a gumstix asap
[17:49] <jcoxon> i saw your mailing list post
[17:52] <phatmonkey> this tweener board he is talking about
[17:52] <phatmonkey> http://gumstix.com/spexExpnsion.html
[17:52] <phatmonkey> the piccy there looks like I can stack it
[17:53] <jcoxon> yeah you can
[17:53] <phatmonkey> would that give me that RS-232 port for a serial console?
[17:53] <jcoxon> iirc
[17:53] <jcoxon> yup
[17:53] <phatmonkey> then I can use the two TTL ports on the robostix for the gps and phone
[17:53] <phatmonkey> neato
[17:53] <jcoxon> guess so
[17:53] <phatmonkey> sticks out a bit though... looks like it'll snap off
[17:53] <phatmonkey> hee hee
[17:54] <jcoxon> i've never really used a robostix
[17:56] <phatmonkey> all these -ix suffixes are starting to get on my nerves, I have to admit
[17:56] <phatmonkey> not as bad as kde i guess
[17:56] <phatmonkey> hehe
[17:56] <jcoxon> the only one that annoys me is gpstix
[17:56] <jcoxon> as it should really be gpsstix
[17:56] <jcoxon> but thats just silly
[17:57] <defy> i thought it was gpsstix?
[17:57] <defy> lol
[17:57] <jcoxon> oh it is
[17:57] <jcoxon> hehe
[17:57] <jcoxon> oops
[17:57] <defy> i always say gpstix anywa
[17:58] <defy> y
[17:58] <jcoxon> unless you say GPSstix
[18:05] <phatmonkey> all the same really
[18:09] <phatmonkey> holy crumbcakes
[18:09] <phatmonkey> leon heller is on that mailing list, he gave me the siemens m20 terminal!
[18:09] <phatmonkey> and suggested a gumstix, guess that's why
[18:09] <phatmonkey> hehe
[18:31] <phatmonkey> Tiger^, have you got a website to put all the stuff up on?
[18:35] <phatmonkey> itching to see the photos :D
[18:35] <defy> hehe
[18:42] <icez> you guys know any website to look up research articles? (not really anything to do with computers..)
[18:42] <icez> i know of one but i forgot it's name:[

[20:47] <phatmonkey> hmm, the gumstix isn't quite as perfect as i hoped it would be
[20:48] <phatmonkey> this whole serial port issue is a right pain
[20:48] <jcoxon> oh
[20:48] <jcoxon> think laterally
[20:48] <jcoxon> bluetooth gps?
[20:48] <jcoxon> cfstix gps
[20:48] <phatmonkey> with the thingymawidget with a weird name (the one with an RS-232 port)
[20:48] <phatmonkey> that stacks
[20:49] <phatmonkey> I have a GPS now that runs on /over/ 6v
[20:49] <phatmonkey> which is a right pain... everything i have runs on 5v
[20:49] <phatmonkey> I had found the 5v equivalent of it that used TTL serial levels
[20:50] <phatmonkey> I could either use a DC-DC convertor for the one I have at the moment (which uses RS-232 levels) or find the equivalent that runs at 5v with rs-232 levels
[20:50] <phatmonkey> cheaply, i'm not paying full price for it ;)
[20:50] <phatmonkey> then I could hook that up to the thingamawidget with the weird name
[20:51] <jcoxon> surely you could use a gpstix, with phone, spare serial port like i have
[20:51] <phatmonkey> the first TTL serial port on the robostix I can use as a serial console as normal
[20:51] <phatmonkey> the second I could hook up directly to the phone (ttl levels... should work?)
[20:52] <phatmonkey> gpstix is fscking expensive
[20:52] <jcoxon> why not stick a netstix on top and use it as the console
[20:52] <jcoxon> you don't need a serial console all the time
[20:52] <phatmonkey> i'm using a basix for the mmc card
[20:52] <jcoxon> netmmc then
[20:53] <phatmonkey> ... then i'm wasting power on a network interface
[20:53] <phatmonkey> network would be nice though
[20:53] <jcoxon> turn it off
[20:53] <phatmonkey> wodner how much power it consumes
[20:53] <jcoxon> i can't see why you can't turn it off
[20:53] <jcoxon> using the proc_gpio driver
[20:53] <jcoxon> change the gpios to something else
[20:53] <phatmonkey> ah, can you?
[20:53] <jcoxon> probably
[20:54] <phatmonkey> eheheh, but then how do I turn it on again?
[20:54] <jcoxon> reboot
[20:54] <jcoxon> have a push button
[20:54] <phatmonkey> hmmm
[20:54] <jcoxon> on another gpio
[20:55] <phatmonkey> with the tweener, i do get an extra serial port
[20:55] <phatmonkey> not clear how i hack it though
[20:55] <jcoxon> there are 4 possible serial ports
[20:56] <phatmonkey> well can I turn off the serial console? if I can, i could use the net-mmc
[20:56] <jcoxon> ffuart, stuart, btuart and hwuart
[20:56] <jcoxon> yeah easy
[20:58] <phatmonkey> the connex has the 92pin connector and the basix doesn't, correct?
[21:00] <phatmonkey> I will ask on the mailing list whether i can definately turn off the network adaptor
[21:00] <phatmonkey> nice if I could
[21:01] <phatmonkey> how do you turn off the serial console then?

[21:20] <jcoxon> really well done
[21:20] <Tiger^> thanks
[21:21] <jcoxon> good old phone
[21:21] <Tiger^> what's interesting
[21:21] <jcoxon> i'm still working my way through
[21:21] <Tiger^> you know how long the flight lasted?
[21:21] <Tiger^> 1.5h
[21:21] <Tiger^> ascent&descent.
[21:21] <jcoxon> max altitude?
[21:22] <Tiger^> 95000 feet :)
[21:22] <jcoxon> wow
[21:22] <Tiger^> yeah
[21:22] <jcoxon> thats amazing
[21:23] <jcoxon> http://moo.pl/~tygrys/junk/bal/cam-sidelooking/40.html
[21:23] <jcoxon> is that the moon?
[21:23] <Tiger^> yep :)
[21:24] <jcoxon> :-D
[21:24] <Tiger^> you know, i thought it was going to be hopeless
[21:24] <Tiger^> and everything went smoothly
[21:25] <Tiger^> no glitches.
[21:25] <jcoxon> hehe
[21:25] <jcoxon> how long did it travel?
[21:26] <Tiger^> i didn't check yet, but i think no more than 5-6km
[21:26] <jcoxon> what!
[21:26] <Tiger^> that's right!
[21:26] <jcoxon> up and then down!
[21:26] <Tiger^> yup, we made a mistake of driving in the direction we thought it'd go
[21:26] <Tiger^> and we had to come back :)
[21:28] <Tiger^> pity i used these crappy cameras
[21:28] <jcoxon> next time?
[21:28] <jcoxon> its not worth the risk of losing everything
[21:28] <Tiger^> yeah, next time i'll use a resolution which will allow me to count farmer Ned's cows from 100000 feet
[21:29] <Tiger^> :D
[21:29] <jcoxon> haha
[21:29] <jcoxon> any damage at all?
[21:29] <Tiger^> nope
[21:29] <Tiger^> not a scratch

[21:30] <Tiger^> yeah
[21:30] <Tiger^> the balloon
[21:30] <Tiger^> and the chute
[21:31] <Tiger^> the balloon (the remains) was so tightly curled
[21:31] <jcoxon> ooo
[21:31] <jcoxon> do you mind if we put you on ukhas/
[21:31] <jcoxon> ?
[21:31] <Tiger^> that when i picked it up i thought i picked a rock with it accidentaly :)
[21:32] <Tiger^> jcoxon: not at all :)
[21:32] <jcoxon> cool
[21:32] <Tiger^> a successful russian strategy flight
[21:32] <Tiger^> requires some good propaganda afterwards
[21:32] <Tiger^> ;>
[21:35] <jcoxon> what info would you like me to include?
[21:35] <jcoxon> I've got picture links and height
[21:35] <Tiger^> hmm
[21:35] <Tiger^> i'll have more info tomorrow - when i check and log into all the gizmos
[21:36] <jcoxon> right cool
[21:36] <jcoxon> well i'll just post that and then we can add more later!
[21:36] <Tiger^> ok
[21:36] <Tiger^> :)
[21:36] <jcoxon> is there a name for your project?
[21:38] <Tiger^> yeah, Cygnus High Altitude Balloon
[21:38] <Tiger^> and the official flight name was Cygnus-2
[21:39] <jcoxon> what happened to 1?
[21:39] <Tiger^> which is a bit of a misnomer
[21:39] <jcoxon> :-)
[21:39] <Tiger^> it was canceled when the damn car broke down
[21:39] <Tiger^> :>
[21:40] <jcoxon> oh ofcourse
[21:40] <phatmonkey> Tiger^, you from the uk?
[21:40] <Tiger^> phatmonkey: nope. Poland :)
[21:40] <phatmonkey> ah right
[21:40] <phatmonkey> v nice pictures btw
[21:40] <jcoxon> but it can go on UKHAS :)
[21:41] <Tiger^> phatmonkey: thanks :)
[21:41] <Tiger^> yeah, since i'm a honorary member ;P
[21:41] <jcoxon> there
[21:41] <jcoxon> rather simple
[21:42] <jcoxon> we can change it if you want
[21:42] <Tiger^> no, that's fine :)
[21:42] <phatmonkey> http://moo.pl/~tygrys/junk/bal/cam-sidelooking/41.html
[21:42] <phatmonkey> wow
[21:43] <phatmonkey> http://moo.pl/~tygrys/junk/bal/cam-sidelooking/91.html
[21:43] <phatmonkey> looks like a thunderstorm top right!
[21:44] <jcoxon> phatmonkey, did you see icez logos?
[21:44] <phatmonkey> yeah
[21:44] <phatmonkey> looked nice
[21:44] <phatmonkey> we really need to sort out the site
[21:44] <phatmonkey> got an exam tomorrow, thursday and monday
[21:44] <phatmonkey> then it's over
[21:45] <phatmonkey> i can probably do stuff thursday - saturday, not much revision for the exam on monday
[21:46] <jcoxon> lets wait till your finished
[21:46] <jcoxon> i've got a mayball tomorrow
[21:46] <jcoxon> and then potentially a launch on the weekend
[21:46] <phatmonkey> okay
[21:46] <phatmonkey> i'm going to wait a few days to make sure I don't change my mind, then i'll order the gumstix and my development plane
[21:46] <Tiger^> phatmonkey: hmm, maybe it is. they predicted thunderstorms for today.
[21:48] <phatmonkey> jcoxon, i might still do that test but I probably won't
[21:48] <phatmonkey> as long as I write the software to keep calibrating the mean of the sky and the ground, it should be fine
[21:49] <phatmonkey> there should be enough radiation coming from the ground to tell the difference between the sky and the ground, it just won't be as much
[21:49] <jcoxon> there will be a load of balloons being launched this summer from cambridge
[21:49] <jcoxon> i see no reason why you can't hitch a ride if you need to
[21:50] <jcoxon> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/construction/CIMG0147.JPG
[21:50] <jcoxon> Peg III
[21:52] <phatmonkey> ah sweet
[21:52] <phatmonkey> hitching rides would be /so/ useful
[21:52] <phatmonkey> once we have the autopilot developed on the powered plane, I see no nice way of testing it as a glider
[21:53] <phatmonkey> except for kites and lobbing it off very tall hills
[21:53] <phatmonkey> will you be putting the radio on PIII then?
[21:53] <jcoxon> if its in august then i don't see why i can't help - i'm part of the permission for launching - we can launch when we want till sept 15th
[21:53] <jcoxon> radio is onboard
[21:53] <phatmonkey> nice
[21:54] <jcoxon> bottom left hand
[21:54] <Tiger^> sweet indeed
[21:54] <Tiger^> you should make captions
[21:54] <phatmonkey> that's what flickr is for ;)
[21:54] <phatmonkey> <phatmonkey> jcoxon, do you have a good supplier for antennas, passive I guess
[21:55] <jcoxon> give me time :-)
[21:55] <jcoxon> i don't do passive
[21:55] <jcoxon> i've got a active:
[21:55] <jcoxon> http://www.srcf.ucam.org/~jac208/pegasus/activegps.html
[21:55] <phatmonkey> you really need an external aerial for that phone - all that padding is probably reducing the range
[21:56] <phatmonkey> are active antennas just better then?
[21:56] <jcoxon> oh the aerial is sticking out hte side
[21:56] <Tiger^> hehe
[21:57] <Tiger^> so it's external ;>
[21:57] <jcoxon> active are better as they give you more cable
[21:57] <jcoxon> so you can burty the gumstix and still get gps
[21:57] <jcoxon> bury*
[21:59] <phatmonkey> ah yes
[22:00] <phatmonkey> i want to bury the antenna, but inside the wing to outside the wing isn't far... and I don't want masses of cable
[22:00] <phatmonkey> bury the gps rather
[22:00] <phatmonkey> i haven't managed to find anyone who stocks antennas
[22:02] <jcoxon> ebay
[22:03] <phatmonkey> they all advertise something along the lines of "WOW! 9 FEET OF CABLE!"
[22:03] <phatmonkey> I don't know what effect cutting the antenna wire would have
[22:03] <phatmonkey> can't be pretty
[22:04] <jcoxon> can't imagine it is
[22:05] <phatmonkey> http://members.shaw.ca/sonde/hardware.htm
[22:05] <phatmonkey> http://members.shaw.ca/sonde/images/guts06.jpg
[22:05] <phatmonkey> argh, i want that antenna!
[22:08] <jcoxon> ;-)
[22:18] <phatmonkey> god, it's really interesting reading over art's flights
[22:20] <jcoxon> right i've added those to flickr and also added some captions
[22:20] <phatmonkey> you can add notes too
[22:20] <phatmonkey> little squares of roll-overable info
[22:21] <phatmonkey> ohw ait, you did that, ignore me!
[22:21] <jcoxon> hehe
[22:21] <phatmonkey> how do you protect the gumstix?
[22:21] <jcoxon> its in a case
[22:21] <phatmonkey> i don't really want to put it in bare, it'll probably get squished by something else
[22:21] <phatmonkey> a specific case?
[22:21] <jcoxon> i hacked up the old waysmall case from peg I
[22:22] <phatmonkey> oh right
[22:22] <jcoxon> just to fit the gps connector
[22:22] <phatmonkey> oh well, i'm sure i can find something
[22:22] <jcoxon> yeah
[22:22] <jcoxon> don't send it bare
[22:22] <phatmonkey> mounting the equipment in the plane is the last of my worries really
[22:22] <jcoxon> hehe
[22:23] <phatmonkey> http://www.flickr.com/photos/29158271@N00/153200550/ add that to...
[22:23] <phatmonkey> http://www.flickr.com/groups/make/
[22:23] <phatmonkey> really high traffic pool
[22:23] <phatmonkey> oh, and make magazine rocks
[22:23] <phatmonkey> great fun
[22:24] <phatmonkey> http://www.flickr.com/photos/phatmonkey/ - eheh, biology revision was boring me
[22:24] <jcoxon> you reckon it counts?
[22:24] <phatmonkey> yeah, definately
[22:24] <phatmonkey> exactly the sort of thing make loves
[22:25] <phatmonkey> I think I found your project on their blog originally...
[22:25] <jcoxon> i should mention its a gumstix hack
[22:25] <phatmonkey> or was it hackaday?
[22:25] <jcoxon> not hackaday?
[22:25] <phatmonkey> hmm, i forget
[22:25] <jcoxon> hackaday
[22:25] <phatmonkey> you were on their blog though
[22:25] <phatmonkey> ok, maybe you weren't
[22:25] <phatmonkey> back to sleep i go
[22:26] <phatmonkey> you should have been ;)
[22:26] <jcoxon> done
[22:27] <phatmonkey> nice
[22:27] <phatmonkey> http://www.flickr.com/photos/fokket/160560928/
[22:27] <phatmonkey> i love that picture so much, oh man
[22:27] <phatmonkey> hee hee hee
[22:29] <phatmonkey> http://members.shaw.ca/sonde/launch_4.htm
[22:29] <phatmonkey> We lost a few minutes of telemetry when the windows printer driver crashed, taking down the ground software.
[22:29] <phatmonkey> see that's why nobody should use windows for anything that needs to be vaguely reliable, urk
[22:32] <Tiger^> hehe
[22:32] Action: Tiger^ uses windows for telemetry. doesn't crash.
[22:33] <phatmonkey> it will one day ;)
[22:33] <phatmonkey> well, that was probably in the days of windows 98
[22:33] <phatmonkey> nope, 2002/03
[22:34] <jcoxon> right i'm now on make blog
[22:34] <jcoxon> haha
[22:34] <phatmonkey> hahahaha
[22:34] <phatmonkey> typical ;)
[22:34] <jcoxon> prepare for traffic
[22:35] Action: jcoxon braces the server (even though he has no idea where the server really is - somewhere in cambridge)
[22:37] <jcoxon> i must say that was fast
[22:38] <phatmonkey> i can imagine that guy sitting there hitting refresh on the flickr pool every 5 minutes
[22:38] <phatmonkey> hmm...
[22:38] <jcoxon> well it is normal time in the US
[22:38] <phatmonkey> true
[22:40] <icez> i like your trebuchet phatmonkey
[22:40] <phatmonkey> ee hee hee, yes, it is great fun
[22:40] <icez> lol
[22:45] <phatmonkey> anywho, good night all
[22:45] <phatmonkey> (and if anyone sees a gps antenna, please tell me!)
