[00:00] <natrium42> do you know where?
[00:01] <Laurenceb> no
[00:01] <Laurenceb> but it looks like I shorted two pins together :-/
[00:01] <Laurenceb> hope nothing got tried
[00:01] <Laurenceb> *fried
[00:02] <Laurenceb> good job I have some spare uC
[00:04] <Laurenceb> that was a pretty stupid mistake :(
[00:04] <natrium42> it fried?
[00:04] <Laurenceb> dunno yet
[00:04] <Laurenceb> its only an avr
[00:05] <Laurenceb> just dismantling everything atm to get to the board
[00:05] <Laurenceb> I'd rebuilt some of the servo driver wiring so it could use pwm capture
[00:10] <Laurenceb> well I've found where the short is - it shouldnt have damaged the uC so thats promising...
[00:17] <Laurenceb> I suspect theres some metal filings got in somewhere :/ prob best to use an air duster I guess
[00:22] Action: Laurenceb invests in a new brain
[00:22] <Laurenceb> there a trace between the two short points
[00:22] <Laurenceb> arggg its veroboard ffs
[00:27] <fnoble> pcbsare cheap to get made these days
[00:36] <Laurenceb> yeah
[00:36] <Laurenceb> I've got quite a few from batchpcb
[00:37] <Laurenceb> but you have to be sure what your design is first - I made the main rogallo board on veroboard as it was clearly going to be modified a few times
[00:37] <Laurenceb> and it has :P
[00:42] <fnoble> yeah cool
[00:42] <fnoble> getting there though by the sound of it
[00:50] <Laurenceb> hmm it still hangs
[00:51] <Laurenceb> seems to hang as soon as the ground control interrupt is turned on, I suspect my wait routines are screwed up
[01:21] Action: SpeedEvil wants a desktop PCB station.
[01:21] <SpeedEvil> Even single-layer'd be nice.
[01:22] <SpeedEvil> Automated I mean.
[01:23] <Laurenceb> eagle?
[01:23] <Laurenceb> oh for manufacturing
[01:24] <Laurenceb> use a laser printer
[01:29] <SpeedEvil> Yeah. I mean a box which I click 'print' and out comes a PCB.
[01:29] <SpeedEvil> Half an hour later, without the expose->develop->etch or laminate->release->etch cycle

[07:04] <Laurenceb> one from the car the other relayed from the car
[07:04] <Laurenceb> and coming down from the balloon on 434 MHz
[07:05] <Laurenceb> oh the fun you could have with this XD
[07:05] <smooth_penguin> cool
[07:05] <smooth_penguin> how long will the baloon be up for?
[07:05] <Laurenceb> ~2 hours
[07:06] <smooth_penguin> k, what size?

[07:24] <jcoxon> yeah i saw
[07:24] <jcoxon> so we'll have the flight on here as well as my chase car as well
[07:24] <jcoxon> should look really good
[07:25] <Laurenceb> this is like james bond or something
[07:25] <Laurenceb> spying on people
[07:25] <jcoxon> hehe
[07:25] <Laurenceb> hmm I'd say going down the A57 was a really bad idea
[07:25] <jcoxon> right forecast traj is reasonable

[10:27] <natrium42> why does firefox 3.1 not start anymore :S
[10:27] <natrium42> now i have to use 3.03 which is slower
[10:27] <The-Compiler> Will it actually launch in 2 minutes or am I wrong or will it just start launching in 2 mins?
[10:28] <natrium42> it all depends if they can prepare it in that time
[10:28] <natrium42> my guess is that they will launch as soon as they are ready
[10:28] <natrium42> jcoxon wanted to launch by 11am since the winds are going to become worse later

[11:22] <natrium42> yep
[11:23] <natrium42> which ones?
[11:23] <natrium42> oh
[11:23] <Laurenceb> the one jcoxon just put on here

[11:26] <natrium42> added
[11:26] <Laurenceb> cool
[11:27] <Laurenceb> wow thats like straight up
[11:27] Action: Laurenceb looks out of window
[11:27] <Laurenceb> yeah theres virtually no wind
[11:30] <The-Compiler> does the tracker update automatically or should I refresh manually?
[11:30] <natrium42> automatically
[11:30] <Laurenceb> the tracker does
[11:30] <The-Compiler> okay
[11:30] <Laurenceb> not sure about the photos
[11:30] <Laurenceb> natrium?
[11:30] <natrium42> photos are also automatic
[11:30] <natrium42> my guess is there is some problem
[11:31] <natrium42> and jcoxon is trying to fix it
[11:31] <The-Compiler> What's CHASE_RJH by the way?
[11:31] <natrium42> one of the chase cars
[11:32] <The-Compiler> ah so 1 is the car and 2 the ballon
[11:32] <natrium42> yep
[11:32] <natrium42> we aren't getting any updates from the balloon for some reason
[11:32] <natrium42> only from that car
[11:32] <The-Compiler> altitude is meters away from sea hight? (sorry, I'm not English)
[11:32] <Laurenceb> I think jcooxn is probably too busy

[11:41] <The-Compiler> ah no sorry my fault
[11:42] <The-Compiler> but the end of 1 connects to 2
[11:42] <natrium42> there's actually a 2 hidden in there
[11:43] <The-Compiler> whoa what a mess of points
[11:43] <The-Compiler> I don't think they are correct, are they?
[11:43] <natrium42> they should be
[11:43] <natrium42> gps is not 100% precise

[11:53] <jcoxon> yeahm lots of lift

[11:53] <jcoxon> yeah we know
[11:53] <Laurenceb> wow crazy

[11:55] <natrium42> so about 1.5 hours for ascent, eh?
[11:55] <Laurenceb> funny if it lands in the smae field
[11:55] <natrium42> a bit less
[11:55] <natrium42> haha, that would be major win

[11:56] <natrium42> 30000/350
[11:56] <Laurenceb> ah

[12:08] <natrium42> next time?
[12:09] <Laurenceb> maybe ... working on it atm
[12:09] <Laurenceb> think something is very wrong with this avr... it hangs when theres a capacitive load on the pwm

[12:14] <natrium42> is it still close by? maybe you can see it land?

[13:24] <Laurenceb> hmm
[13:24] <Laurenceb> wonder if the periodic bands of interference are manual retuning
[13:26] <Laurenceb> I think that was jcoxons problem with the setup
[13:26] <Laurenceb> the bandpass filter on the rx is narrow
[13:27] <Laurenceb> the sections of the picture between the interference bands are really good

[15:18] <Max0> hi
[15:18] <Laurenceb> hopefully jcoxon will be back online soon
[15:18] <Max0> :)
[15:18] <Cooleo-M> Anyone remeber me? I came earlier in the year planning mine, but I didn't have funding and said I would come back when I had funding...so hai :D
[15:18] <Laurenceb> http://www.flickr.com/photos/jcoxon77/
[15:18] <Laurenceb> hi
[15:18] <Cooleo-M> So yeah, I should have my launch in a couple of weeks.
[15:19] <Cooleo-M> Mearly a 100 Meter high one.
[15:20] <Laurenceb> nice
[15:20] <Laurenceb> where are you?
[15:20] <Cooleo-M> Lowestoft,Suffolk
[15:20] <Laurenceb> ah neat
[15:20] <Laurenceb> Guildford Surrey
[15:21] <Cooleo-M> Im using a Balloon cluster, but I havent got the hardware I can just chuck away yet :P. So i've got string limiting it to 100 meters. or maybe 1KM
[15:21] <Laurenceb> most of the guys are based around Cambridge
[15:21] <Cooleo-M> Laurenceb: Cool :D
[15:21] <Cooleo-M> I can remeber.
[15:21] <Max0> i have a similar system to Pegasus IV
[15:21] <Cooleo-M> I watched somthing which was done on google maps
[15:21] <Cooleo-M> Landed near thetford.
[15:21] <Laurenceb> yep
[15:21] <Max0> router and 5110 but having problems adding the serial connection so thought jcox might be able to help
[15:21] <Laurenceb> http://spacenear.us/tracker/
[15:21] <Cooleo-M> Then I left because I had money to do my project.
[15:21] <Laurenceb> I use microcontrollers
[15:21] <Cooleo-M> Now since Schools started up again, I have money :D
[15:22] <Cooleo-M> So yeah, I just need to get 1KM of string.. Haha.
[15:23] <Cooleo-M> Not much is gonna be in my payload ether, Probably just a camera.
[15:23] <Laurenceb> be carful what the CAA say about that
[15:23] <Cooleo-M> Haha
[15:23] <Cooleo-M> Theres hardly any aviation traffic round here.
[15:24] <Cooleo-M> Hmnm
[15:24] <Cooleo-M> Maybe just 250 meters then
[15:25] <Cooleo-M> Because I only have like £40
[15:25] <Cooleo-M> and thats gotta pay for helium, balloons and hardware
[15:42] <Cooleo-M> Hmm
[15:43] <Cooleo-M> Might be able to do on the 15th
[15:44] <Laurenceb> what hardware are you using?
[15:45] <Cooleo-M> Probably just a camera for the first one
[15:45] <Cooleo-M> I have a GPS upstairs with PS2 connection
[15:45] <Laurenceb> recovery?
[15:45] <Cooleo-M> but I have no idea how to get that started.
[15:45] <Cooleo-M> Im just gonna hope I can see it when it comes back.
[15:45] <Cooleo-M> Air rifle and shoot it down probably
[15:45] <Laurenceb> there should be a bit of guidance on the wiki
[15:46] <Cooleo-M> Hmm
[15:46] <Cooleo-M> Its going to be expensive though
[15:47] <Laurenceb> £200 to £300 is m rough estimate for something good
[15:48] <Cooleo-M> Indeed, I can't afford that in the slightest
[15:48] <Laurenceb> you a student?
[15:48] <Cooleo-M> Indeed.
[15:49] <Laurenceb> uni?
[15:50] <Cooleo-M> Nah, A-Levels.
[15:51] <Laurenceb> arg
[15:51] <Laurenceb> stressful
[15:51] <Laurenceb> have you just finished As?

[15:56] <Laurenceb> dont you want to study something more useful?
[15:56] <Cooleo-M> What like?
[15:56] <Laurenceb> physics? chemistry?
[15:56] <Cooleo-M> I was going to Physics but it clashed with IT.
[15:56] <Laurenceb> maths mech?
[15:56] <Laurenceb> sucks
[15:56] <Cooleo-M> And I took IT because I knew I would get good grades in it.
[15:56] <Laurenceb> I wanted to do desgn tech but it clashed
[15:56] <Cooleo-M> Damn
[15:57] <Laurenceb> well thats one option :P

[16:46] <jcoxon1> I remember
[16:46] <Cooleo-M> :)
[16:46] <jcoxon1> Mixed you up with some one else at first
[16:46] <Cooleo-M> But yeah, I got this GPS which connects via PS/2. No idea what to do with it
[16:47] <Cooleo-M> Hmm
[16:47] <Cooleo-M> Should be able to try my cluster on the 23rd
[16:48] <jcoxon1> PS/2. urgh. You sure is not serial. What make is it?
[16:48] <Cooleo-M> let me go find it
[16:51] <Cooleo-M> Found,
[16:51] <Cooleo-M> It says Model No.: HI-204E
[16:51] <Cooleo-M> Ill google it
[16:52] <Cooleo-M> Haicom
[16:53] <Cooleo-M> Connections
[16:53] <Cooleo-M> Connector Type: Serial - 6 pin mini-DIN (PS/2 style)
[16:54] <jcoxon1> Oh i know it
[16:55] <Cooleo-M> :D
[16:55] <Cooleo-M> Can I use it for anything?
[16:55] <jcoxon1> Its a serial rs232 device
[16:55] <Cooleo-M> So thats good?
[16:57] <SpeedEvil> yes
[16:57] <Cooleo-M> Yay
[16:57] <jcoxon1> What are you going to use for your flight computer?
[16:58] <Cooleo-M> what ever I can get cheapest.
[16:58] <SpeedEvil> I've got a ZX81 motherboard.
[16:58] <jcoxon1> Any experience with micro processors?
[16:59] <Cooleo-M> Nope
[16:59] <SpeedEvil> Cooleo-M: you can have it free.
[16:59] <jcoxon1> If not i recommend an arduio
[16:59] <Cooleo-M> SpeedEvil: Spectrum?xD
[16:59] <SpeedEvil> No - ZX81.
[16:59] <jcoxon1> Ardunio*
[16:59] <SpeedEvil> I think I might have the RAM pack somewhere.
[16:59] <Cooleo-M> Whats a ZX81?
[17:00] <SpeedEvil> It's the ancestor of the spectrum
[17:00] <Cooleo-M> haha.
[17:00] <jcoxon1> Haha
[17:00] <Cooleo-M> jcoxon: Arn't the arduino about £20?
[17:00] <jcoxon1> Yeah, but they are quite easy to program
[17:01] <jcoxon1> There are cheaper things but they'll need soldering and are difficult to program
[17:03] <Cooleo-M> Hmm
[17:03] <Cooleo-M> Will I only need to buy the ardino, Or will I have to buy more hardware on top of that?

[17:04] <Cooleo-M> Will I need to buy more hardware? I suck at soldering.
[17:04] <Cooleo-M> Or just the ardiuno?
[17:05] <jcoxon1> You'd need some form of communication such as a radio transmitter

[17:38] <Cooleo-M> SpeedEvil: Dont think so
[17:38] <Cooleo-M> No idea though
[17:38] <SpeedEvil> Cooleo-M: does it have batteries?
[17:38] <Cooleo-M> I plugged it into my PDA when I had it and it would power on
[17:38] <Cooleo-M> SpeedEvil: No

[17:39] <Cooleo-M> Thats my GPS
[17:39] <Laurenceb> oh hes gone
[17:39] <Laurenceb> anyone know the burst altitude?
[17:40] <Cooleo-M> Can anyone help me to make a serial to USB adapter?
[17:40] <SpeedEvil> Cooleo-M: you buy those
[17:41] <hallam> it's hard to say
[17:41] <Cooleo-M> SpeedEvil: You can?
[17:41] <hallam> it really depends whether the signal levels are TTL or RS232
[17:41] <SpeedEvil> Cooleo-M: buy a serial adaptor, and connect up the cable corectly.
[17:41] <SpeedEvil> that too.
[17:41] <SpeedEvil> Forgot that.
[17:41] <Cooleo-M> SpeedEvil: I cant find any for the PS2 to USB
[17:41] <SpeedEvil> Cooleo-M: you won't. The other problem is that you need to work out the power wires.
[17:42] <Cooleo-M> SpeedEvil: How?
[17:42] <SpeedEvil> Cooleo-M: startiong with a voltmeter would be good.
[17:42] <hallam> if it's TTL, use this: http://www.ftdichip.com/Products/EvaluationKits/TTL-232R.htm
[17:42] <SpeedEvil> Open it up, find the main decoupling cap into the cable., ...
[17:42] <hallam> if it's RS232, use any USB-to-serial converter
[17:43] <hallam> honestly if all you want is to add GPS to your PC it may be cheaper to just buy a USB GPS module
[17:43] <Cooleo-M> SpeedEvil: I have to buy a volt meter
[17:43] <Cooleo-M> hallam: Really?
[17:43] <hallam> possibly
[17:43] <Cooleo-M> This GPS is worth like £100
[17:43] <hallam> sure, but you can get a cheap USB GPS stick for half that price
[17:43] <hallam> and GPS is GPS
[17:43] <Cooleo-M> But..This GPS is worth £100 D:
[17:44] <Cooleo-M> and I have it next to me
[17:44] <hallam> it depends what you want to spend your time and money on
[17:44] <SpeedEvil> why do you think it's worth 100?
[17:44] <hallam> Did it cost £100, or is it worth £100?
[17:44] <Cooleo-M> Because thats how much they were selling for on that site
[17:44] <SpeedEvil> that doesn't actually mean anything.
[17:44] <Cooleo-M> Damn
[17:44] <SpeedEvil> Unless you need a GPS that plugs into that connector, it's _way_ overpriced.
[17:45] <SpeedEvil> As in maybe 10-15 quid real value for hackers.
[17:45] <edmoore> the best gps chipsets you can buy for <£400 are about £30
[17:45] <SpeedEvil> If it's a displayless dongle.
[17:45] <Cooleo-M> Oh
[17:45] <Cooleo-M> So this GPS is useless? :(
[17:45] <edmoore> i.e. before you start spending real money, nothing will do you better than, say, a ublox 5
[17:46] <Cooleo-M> I just want this so I can use it with my laptop first
[17:46] <SpeedEvil> Cooleo-M: it's not useless.
[17:46] <Cooleo-M> and its not a Mini DIN-8.
[17:46] <Laurenceb> yeah
[17:46] <Cooleo-M> SpeedEvil: What can I use it for?
[17:46] <SpeedEvil> Cooleo-M: I could probably get it working in 5 mins or so, as could Laurenceb.
[17:46] <Laurenceb> ublox5 seems to be the best atm
[17:46] <Laurenceb> very impressive
[17:46] <SpeedEvil> Cooleo-M: teaching you how to get it working is a whole lot harder/.
[17:46] <Cooleo-M> Laurenceb: Wanna buy it off me?
[17:46] <Cooleo-M> Thats alot easier
[17:46] <Laurenceb> no thanx
[17:47] <Cooleo-M> SpeedEvil: You want it?
[17:47] <Laurenceb> I have a plethora of gps modules :P
[17:47] <Cooleo-M> D:
[17:47] Action: SpeedEvil has too much crap ATM.
[17:47] <hallam> yeah I have them out the wazoo as well
[17:47] <Cooleo-M> Laurenceb: Any USB ones?
[17:47] <Cooleo-M> sWAP :d
[17:47] <Cooleo-M> *Swap :D
[17:47] <Laurenceb> nope
[17:47] <Laurenceb> all modules/eval boards
[17:47] <hallam> we can help you get it working, it'd probably be a good learning exercise
[17:47] <Cooleo-M> :D
[17:47] <Cooleo-M> So how can I wire this to USB?
[17:47] <hallam> but it depends what your objectives are, if you just want something to work then honestly you should just buy a cheap USB GPS
[17:48] <hallam> you do need a serial-to-usb adapter, like you said
[17:48] <Cooleo-M> Ah
[17:48] <SpeedEvil> http://shop.ebay.co.uk/?_from=R40&_trksid=m38.l1313&_nkw=usb+gps
[17:48] <hallam> but first we have to work out what kind of serial it is
[17:48] <hallam> because there are several kinds of serial
[17:48] <SpeedEvil> And a serial-USB adaptor will cost about a third of what a boxed USB GPS thingy will.
[17:48] <Laurenceb> btw I dont know if I said earlier about issues with the atmega168 and pwm/spi on portb, I was thinking about the problem and might have an answer
[17:49] <Laurenceb> both spi and pwm OC1B can overide the data direction register
[17:49] <hallam> you're also going to be a bit fucked without a voltmeter
[17:49] <hallam> I can recommend a good voltmeter
[17:49] <Cooleo-M> I should get some
[17:49] <SpeedEvil> http://cgi.ebay.co.uk/New-Holux-M241-USB-Bluetooth-GPS-Receiver-Data-Logger_W0QQitemZ400005958909QQcmdZViewItem?hash=item400005958909&_trksid=p3286.c0.m14&_trkparms=72%3A1300|66%3A2|65%3A12|39%3A1|240%3A1318
[17:49] <SpeedEvil> Oooh.
[17:49] <SpeedEvil> Cheap.
[17:50] <Cooleo-M> That is cheap
[17:50] <Laurenceb> so what happen is 1) pwm came on 2)SPI on 3)DDR set to output
[17:50] <Cooleo-M> Is that any good on a payload?
[17:50] <Laurenceb> which I think is wrong
[17:50] <SpeedEvil> Cooleo-M: don't know
[17:50] <Cooleo-M> SpeedEvil: :D
[17:50] <Laurenceb> it should be 1)pwm 2)DDR 3)SPI
[17:51] <Laurenceb> then theres no conflict
[17:51] <Laurenceb> but I need to try out the theory now
[17:51] <SpeedEvil> Laurenceb: oh - direction register
[17:51] <Laurenceb> yeah
[17:51] <Laurenceb> its odd
[17:51] <Cooleo-M> Why am I spending cash?! I need to save. Stupid eBay.
[17:51] <Laurenceb> I had to trawl through the datasheets
[17:51] <hallam> that ebay gps doesn't include the USB data cable, though it's probably standard

[17:52] <hallam> this is a bad hobby to get into if you have really no spare cash
[17:52] <Laurenceb> both SPI and PWM can overwride the DDR
[17:52] <Cooleo-M> hallam: Tell me about it.
[17:52] <hallam> it doesn't have to be very expensive, but you should expect to spend a couple of hundred pounds before your first launch
[17:52] <Cooleo-M> :o
[17:52] <hallam> it's kind of a waste of time if you can't do that
[17:52] <Laurenceb> but SPI only if it hasnt been set to output
[17:52] <Laurenceb> hence that order
[17:52] <Laurenceb> yeah £300 really
[17:52] <Cooleo-M> hallam, Im just gonna go it my way :D
[17:53] Action: SpeedEvil is planning his first launch for a tenner.
[17:53] <Cooleo-M> Balloon cluster, then get it shottern down
[17:53] <Cooleo-M> *shot down
[17:53] <Laurenceb> I've probably spent about £1to2K
[17:53] <hallam> SpeedEvil, I guess you already own a multimeter :P
[17:53] <Cooleo-M> :o
[17:53] <Laurenceb> over the past few years
[17:53] <SpeedEvil> hallam: and some foil, a hot-melt gun, and a GPS radiosonde.
[17:53] <Cooleo-M> xD
[17:53] <Laurenceb> but I never keep track
[17:53] <Cooleo-M> So yeah, Mine should work out at about £30 if I can get my remote ignition working
[17:54] <Laurenceb> just whatevers left in the bank after food :D
[17:54] Action: SpeedEvil is planning to avoid remote ignition.

[17:55] <Laurenceb> erm that could still be taken the wrong way I guess
[17:55] <Cooleo-M> Is that good to fill balloons up with?
[17:55] <hallam> it's not good
[17:55] <hallam> but it would work
[17:55] <hallam> hydrogen from NaOH + Al is cheap
[17:55] <Laurenceb> you took the words out of my mouth
[17:56] <SpeedEvil> Cooleo-M: it's not especially great.
[17:56] <Laurenceb> its a bit of a tricky reaction to control
[17:56] <Cooleo-M> SpeedEvil: Im just using helium
[17:56] <SpeedEvil> Cooleo-M: it has half the weight of air, compared to hydrogens 1/16th
[17:56] <hallam> Cooleo, where will you get helium for < £30 ?
[17:56] <Cooleo-M> hallam: ASDA
[17:56] <Cooleo-M> :D
[17:56] <Cooleo-M> SpeedEvil: Hmm, How do you fill it up?
[17:56] <SpeedEvil> But hydrogen is an annoying reaction to make it nice and dry, and the natural gas is on a tap in my kitchen.
[17:56] <Cooleo-M> SpeedEvil: Gas stove?
[17:57] <Laurenceb> I found a helium cyclinder in the street yesterday
[17:57] <SpeedEvil> Laurenceb: kids today. Huffing anything.

[17:58] <Cooleo-M> Damn
[17:58] Action: Cooleo-M needs to think up a way to remotely cut strings
[17:59] <hallam> it's not a very easy problem
[17:59] <Laurenceb> resistor
[17:59] <Laurenceb> 10 ohm 0.125 watt
[17:59] <Cooleo-M> how will that cut a string?
[17:59] <Laurenceb> 5 to 8V dc
[17:59] <Laurenceb> it heats up to ~250C
[18:00] <hallam> how reliable have your cutdowns been, Laurence? I always worry about using a resistor at something like 200 * its power rating
[18:00] <Cooleo-M> Ah :D
[18:00] <hallam> and it failing open
[18:00] <Laurenceb> hallam: 5/5
[18:00] <hallam> not bad
[18:00] <SpeedEvil> A Su29hal: there are resistors rated for 350C temps
[18:00] <Laurenceb> and 100s of ground tests
[18:00] <hallam> that's better than a lot of our explosive designs
[18:00] <Cooleo-M> Laurenceb: So if I got that, Ripped a speaker out of a mobile phone and put that tranisistor in the place, so when I called it, it would work, Right?
[18:00] <Laurenceb> erm
[18:00] <SpeedEvil> hal:
[18:01] <hallam> mobile phones won't work above 2km
[18:01] <Laurenceb> well for a starts there no gsm
[18:01] <SpeedEvil> Cooleo-M: no
[18:01] <SpeedEvil> Cooleo-M: mobiles stop working when up a bit
[18:01] <Cooleo-M> Mine isnt going above 2km o.0
[18:01] <Laurenceb> hmm
[18:01] <hallam> you hope
[18:01] <Cooleo-M> I did read the Wiki
[18:01] <Laurenceb> why not get a basic microcontroller
[18:02] <Laurenceb> maybe a picaxe
[18:02] <Cooleo-M> Hmm
[18:02] <Cooleo-M> Because Im not trusting in this yet :P.
[18:02] <Cooleo-M> I dont want £50+ of hardware flying away
[18:02] <SpeedEvil> The very cheapest way is a cheap PAYG mobile, subscribed to a web-location service.
[18:03] <SpeedEvil> A camera you have lying around with the shutter glued down.
[18:03] <Cooleo-M> SpeedEvil: What networks offer that?
[18:03] <SpeedEvil> And something to make a very loud noise when it lands.

[18:07] <Laurenceb> jcoxon: any idea what caused the horizontal banding?
[18:07] <jcoxon> yeah, if its tune slightly off
[18:07] <jcoxon> remember it comes through line by line
[18:08] <SpeedEvil> rotating antenna
[18:08] <jcoxon> i reckon we could get it better, next launch
[18:08] <jcoxon> and once i fix teh rtty problem
[18:08] <Laurenceb> need slightly larger bandpass filter in the scanner?
[18:09] <Cooleo-M> Hmm

[18:13] <SpeedEvil> Why balloons really burst.
[18:13] <SpeedEvil> http://www.bunny-comic.com/?id=1101
[18:14] <hallam> thanks James :)
[18:14] <Laurenceb> nice
[18:14] <Cooleo-M> jcoxon: I love the pics of yours in the upper atmosphere
[18:15] <jcoxon> Laurenceb, it'll be really good next time :-p
[18:16] <Laurenceb> is the whole log up?
[18:16] <Laurenceb> I can only see up to ~500m
[18:17] <jcoxon> it takes a while to load
[18:18] <jcoxon> max alt was 31394.1M
[18:18] <Laurenceb> nice
[18:18] <Laurenceb> where there photos stored onboard?
[18:19] <Cooleo-M> 101k feet?!
[18:19] <Cooleo-M> Thats higgb
[18:19] <Cooleo-M> *hiiggh
[18:19] <hallam> that's where the higg boson's discovered
[18:19] <jcoxon> Laurenceb, sadly not, the only way i could do remote capture
[18:20] <SpeedEvil> jcoxon: what was furthest distance you could read the text at?
[18:21] <SpeedEvil> In most of them I think the text'd be readable if it was magenta
[18:21] <jcoxon> was thinking about a black band with white letters
[18:22] <SpeedEvil> that too
[18:22] <SpeedEvil> I think magenta'd work almost as well.
[18:22] <hallam> but what if the photo is of a cranberry bog? WHAT THEN?
[18:22] <SpeedEvil> :)

[18:23] <SpeedEvil> For 7 quid.
[18:24] <SpeedEvil> Impact speed?
[18:24] <Laurenceb> I might have a play with the data in gnuplot if I'm feeling exceptionally bored
[18:24] <Laurenceb> just after cutdown
[18:26] <Laurenceb> impact looks to be about 10m/s
[18:26] <jcoxon> yeah the parachute was badly tangled
[18:27] <jcoxon> if you are bored Laurenceb you could make a kml

[18:29] <Laurenceb> I'm not tht bored yet
[18:29] <Laurenceb> just tired
[18:29] <jcoxon> haha i'll do it
[18:29] <Laurenceb> sorry :P
[18:29] <jcoxon> no worries
[18:29] <Laurenceb> just a bit of python
[18:30] <Laurenceb> what are the last two variables?
[18:30] <fnoble> does anyone want a fun challenge?
[18:31] <fnoble> make a cool balloon icon
[18:31] <jcoxon> oh i've done it in ruby
[18:31] <fnoble> to show the position of the payload in my mapping software
[18:32] <Laurenceb> or ... get pwm to work on the /SS pin of an atmega168 :D
[18:36] <hallam> Heh, and it has to be cooler than the balloon icon I made last night ;)
[18:38] <jcoxon> kml done
[18:39] <jcoxon> http://www.pegasushabproject.org.uk/wiki/lib/exe/fetch.php/missions:pegasus.kml.zip?id=missions%3Apegasus6&cache=cache
[18:40] Action: Laurenceb grabs
[18:41] <fnoble> hallam, ive made cool icons for the predicted landing site and the launch site but am stumpped by the balloon
[18:42] <hallam> it's surprisingly hard to do
[18:42] <Laurenceb> hmm
[18:43] <Laurenceb> very interesting trace
[18:43] <Laurenceb> you can see it being carried by the stratospheric vortex above ~20Km
[18:43] <Laurenceb> then theres what appears to be some jet stream on the descent
[18:43] <Laurenceb> more so than on the ascent
[18:44] <jcoxon> its a similar shape to the wyoming forecast
[18:44] <jcoxon> though the forecast thought i'd go more north
[18:48] <Cooleo-M> Lewis Hamilton won :D
[18:48] <jcoxon> oh nice
[18:49] <Cooleo-M> hes now the world champion
[19:00] <Cooleo-M> Anyone got any views on Balsa wood? Have any of you used it for payloads?
[19:00] <jcoxon> Cooleo-M, yeah i have
[19:00] <Cooleo-M> Broken Easily?
[19:00] <SpeedEvil> Laurenceb: http://www.bunny-comic.com/?id=1037
[19:00] <jcoxon> its okay for structure but polystyrene is better - for insulation
[19:00] <jcoxon> nah it doesn't really break
[19:00] <Cooleo-M> Ah :) Alright thanks
[19:01] <SpeedEvil> polystyrene also absorbs energy by crushing in moderately predicatable ways.
[19:01] <Cooleo-M> Ah, Cool.
[19:01] <SpeedEvil> Balsa doesn't quite do that well
[19:01] <Cooleo-M> im still trying to work out this string cutting mechanism
[19:03] <hallam> a trained gerbil with a miniature pair of scissors
[19:04] <Cooleo-M> Haha
[19:04] <Laurenceb> Cooleo-M theres a pic on the wiki somewhere
[19:04] <Laurenceb> just a sec
[19:05] <Laurenceb> http://wiki.ukhas.org.uk/_detail/projects:mihab:p6290015.jpg
[19:06] <Cooleo-M> is that the thing which heats up?
[19:06] <Laurenceb> the yellow line goes up to the envelope
[19:06] <Cooleo-M> Were you making a bomb?
[19:06] <Laurenceb> ?!
[19:06] <Cooleo-M> Laurenceb: ARE YOU FROM LEEDS?!
[19:07] <Cooleo-M> Hmm
[19:07] <Cooleo-M> That might do for cutting the string
[19:07] <Cooleo-M> but, Any idea for remote use?
[19:07] <SpeedEvil> timer
[19:07] <Cooleo-M> Ah
[19:07] <Cooleo-M> Easy to make?
[19:08] <Cooleo-M> or use an egg timer :D
[19:08] <Laurenceb> Leeds? bombs? audatious use of caps lock...
[19:08] <Laurenceb> where is this going?
[19:08] <Cooleo-M> Laurenceb: Theres a giant base of Al-Qaeda in Leeds
[19:08] <Laurenceb> *sigh*
[19:08] <Cooleo-M> Lawl.
[19:08] <Laurenceb> sorry to break the news but hteres no such thing
[19:09] <Cooleo-M> What?
[19:09] <Laurenceb> its a distortion to justify iraq+afganistan
[19:09] <Cooleo-M> oh
[19:09] <Cooleo-M> xD
[19:10] <Cooleo-M> Anyone got a tutorial on how to make a simple timer?
[19:10] <hallam> google 555
[19:10] <Laurenceb> a nutty millionare ex CIA/oil tycoon sitting in a cave with a camcorder isnt exactly world terror
[19:10] <fnoble> hallam, not for high altitude :p
[19:11] <Cooleo-M> fnoble: This wont be going higher than 2km
[19:11] <fnoble> still, will be cold up there
[19:11] <Cooleo-M> at 2km?
[19:11] <Laurenceb> Cooleo_M: come to think of it in one of his videos you can clearly see a cheap yellow multimeter in the background
[19:11] <Laurenceb> as sold by maplins for £4.5
[19:12] <hallam> generally you can tell how good a multimeter is by its colour
[19:12] <hallam> yellow = rubbish
[19:12] <hallam> red = pretty good
[19:12] <hallam> grey = very good
[19:12] <Laurenceb> green?
[19:12] <fnoble> but i guess your timing doesnt have to be very accurate
[19:12] <Cooleo-M> Laurenceb: I doubt he shops in maplin
[19:12] <Cooleo-M> fnoble: True
[19:12] <Laurenceb> you neverknow
[19:12] <Laurenceb> I've seen it on ebay
[19:13] <Cooleo-M> Laurenceb: I doubt he shops on ebay
[19:13] <Laurenceb> well he got the multimeter in his cave somehow
[19:13] <Cooleo-M> Lol
[19:13] <fnoble> hallam, look into the yagi + tripod yet?
[19:13] <Cooleo-M> Iraplins
[19:14] <Laurenceb> I really must find the clip and screenshot it some time
[19:14] <hallam> yeah I've been trying to find a good yagi
[19:14] <hallam> When Robert comes on I'll ask him which model it is
[19:14] <fnoble> cool
[19:14] <Laurenceb> Cooleo-M: its about -55C
[19:14] <hallam> I'm about to order the tripod, anything else you think we want from 7dayshop.com?
[19:14] <Laurenceb> at the tropopause
[19:14] <Laurenceb> (coldest point you'll reach)
[19:15] <Cooleo-M> Laurenceb: at 2km?
[19:15] <fnoble> we could get one of the neat collapsable yagis, dont know the name but someone on here was recommending them
[19:15] <Cooleo-M> I may just buy a rocket instead.
[19:15] <Cooleo-M> Alot easier D:
[19:16] <fnoble> less cool though :)
[19:16] <hallam> Estes make a nice rocket camera kit
[19:16] <Cooleo-M> :P
[19:16] <Cooleo-M> fnoble: Cheaper
[19:16] <Laurenceb> oh 2Km
[19:16] <Laurenceb> no problem then :D
[19:18] <hallam> Cooleo, why not just rely on the balloon bursting to bring it down?
[19:18] <hallam> if you don't care about the exact height too much, you could arrange for it to burst somewhere between 1 and 4km pretty easily
[19:19] <Cooleo-M> hallam: I dont want to loose my camera on board
[19:19] <hallam> oh, you want to push a button and have it cut where you can see it
[19:19] <hallam> fair enough
[19:19] <Cooleo-M> hallam: Indeed
[19:20] <Cooleo-M> I just dont want to loose my digital camera :(
[19:20] <Cooleo-M> Its a decent one
[19:20] <hallam> unless you're intending to launch from one of the registered launch sites, you should apply for permission from the CAA early
[19:20] <hallam> it can take several weeks to go through
[19:20] <Cooleo-M> For 2km high..?
[19:20] <hallam> yes
[19:20] <Cooleo-M> O.O
[19:20] <hallam> anything above about 300m
[19:20] <Cooleo-M> 300 meters it is o.0
[19:20] <hallam> well, check what it actually is
[19:21] <hallam> the permission doesn't cost anything
[19:21] <Cooleo-M> Wheres the nearest registered launch site?
[19:21] <hallam> where are you? there are two near Cambridge
[19:21] <fnoble> we have two in cmbridge
[19:21] <Cooleo-M> Im in Lowestoft, on east coast of suffolk
[19:21] <fnoble> so not too far from you
[19:21] <hallam> just come up to Cambridge then
[19:21] <Cooleo-M> Thats gonna cost train fair :p
[19:21] <Laurenceb> hallam: back in the UK now?
[19:22] <hallam> yes
[19:22] <Laurenceb> cool, whats the plan? do you have another year
[19:22] <Cooleo-M> Is there a train station near teh launch sites?
[19:22] <hallam> the east coast is probably not the best launch site
[19:22] <Cooleo-M> Yeah :P
[19:22] <hallam> graduate in June
[19:23] <hallam> gtfo of this country
[19:23] <fnoble> there is one near-ish
[19:23] <Laurenceb> hehe
[19:23] <Laurenceb> good luck
[19:23] <hallam> Churchill is walkable from Cambridge station, we can show you around
[19:23] <Laurenceb> dont like it here?
[19:23] <Cooleo-M> Ill bring a micro-scooter.
[19:24] <hallam> it has its good points but I want into the land of milk, honey and cheap aviation
[19:24] <Cooleo-M> hallam: America?:D
[19:24] <Laurenceb> USSR ?
[19:24] Action: Laurenceb runs
[19:24] <Cooleo-M> :P
[19:26] <Laurenceb> omg
[19:26] Action: Laurenceb dances
[19:27] <Cooleo-M> :/
[19:27] <Laurenceb> I think I fixed the spi/pwm logjam
[19:27] <SpeedEvil> :)
[19:27] <Laurenceb> and also I can run the spi much fast now
[19:27] <Laurenceb> if you remember I was having to run it really slow
[19:28] <Laurenceb> t get the gyro to give a decent ADC reading, well turns out there was an overflow issue in one of the wait routines
[19:28] <Cooleo-M> :D
[19:28] <Cooleo-M> Hmm
[19:28] <Laurenceb> 10MHz here we come
[19:28] Action: Cooleo-M ponders on using hot air
[19:28] <Cooleo-M> Has anyone tried that?:D
[19:29] <SpeedEvil> Cooleo-M: you need a _much_ bigger balloon.
[19:29] <Cooleo-M> I made one using my toaster today
[19:29] <Cooleo-M> SpeedEvil: I did it with a sandwich bag and a toaster o.o
[19:29] <SpeedEvil> Cooleo-M: and of course a heater
[19:29] <Laurenceb> toast boy
[19:29] <hallam> Cooleo, and how much weight did the sandwich bag lift?
[19:29] <Laurenceb> sorry I couldnt resist it
[19:29] <Cooleo-M> hallam: Itself :D
[19:29] <hallam> there you go
[19:29] <SpeedEvil> Cooleo-M: Helium has a lift of about 1Kg/m^3 (at sea level)
[19:29] <hallam> if you try really hard you can get a payload into about 300g
[19:30] <hallam> hot air has what, 10% of that?
[19:30] <SpeedEvil> Cooleo-M: hot air - maybe 100g/m^3 - with a 30C temp difference.
[19:30] <hallam> so you're looking at 3m^3 just to get it off the ground
[19:30] <Cooleo-M> xD
[19:30] <Cooleo-M> hmm
[19:31] <hallam> it's not that it can't be done, it's just harder than He
[19:31] <Laurenceb> MIR balloon :D
[19:31] <Laurenceb> I seriously looked at building one
[19:31] <Laurenceb> but it needs to be ~10m radius
[19:31] <Cooleo-M> 10M?! That would be huge
[19:32] <Cooleo-M> I couldnt get my toaster to do a plastic bag from ASDA D:
[19:33] <hallam> yeah you'd need an internal heater
[19:33] <hallam> and a power source for that heater
[19:33] <Laurenceb> Cooleo-M: can we trust you not to incinerate the neighbourhood?
[19:33] <Cooleo-M> Comeon, There must be a free way to make balloons float :P
[19:33] <fnoble> hallam, might come over and get that jtag cable now if thats ok?
[19:33] <Cooleo-M> Laurenceb: :D
[19:33] <hallam> sure
[19:34] <fnoble> be there in a sec
[19:34] <hallam> cooleo, you could fill it with vacuum, that doesn't cost anything and it has the best lift per m^3 of any gas
[19:34] <Laurenceb> Cooleo-M: use responsibly
[19:34] <Laurenceb> http://www.overflite.com/index.html
[19:35] <Cooleo-M> Oooooooooooooooooooooooooooo
[19:35] <Laurenceb> oh ogd
[19:35] Action: Laurenceb ducks from flying firebombs
[19:35] <Cooleo-M> Laurenceb: I was just gonna buy one like that on ebay
[19:35] <Cooleo-M> Heh, Ive come across this site before
[19:38] <Laurenceb> seriously itsonly safe to do low altitude tethered flight with stuff like that
[19:38] <Cooleo-M> Hmm
[19:38] <Cooleo-M> http://www.sourcing4u.co.uk/shop/product_info.php?cPath=0_28&products_id=47
[19:38] <Cooleo-M> I was thinking about them
[19:39] <Laurenceb> I made a few meths powered ones with 2.4GHz cams on ages ago
[19:39] <Cooleo-M> Wow, Nice
[19:40] <Laurenceb> yeah until I managed to reverse the power lines in the dark and fried the whole lot
[19:40] <SpeedEvil> MIR?

[19:41] <Laurenceb> yeah
[19:42] <Laurenceb> you can use the vertical IR flux to heat an envelope
[19:42] edmoore (n=edmoore@pomegranate.chu.cam.ac.uk) joined #highaltitude.

[19:42] <Cooleo-M> Hmm
[19:43] <SpeedEvil> How does that work?
[19:43] <Laurenceb> its a bit odd
[19:43] <SpeedEvil> The bottom is black, the top reflective - in IR?
[19:43] <Laurenceb> I think you can derive the theory
[19:44] <Laurenceb> by calculating equilibrium temperature of a dust particle
[19:44] <Cooleo-M> Hmm#
[19:44] <Laurenceb> then assuming an assymetrically radiating envelope
[19:44] <Cooleo-M> I wish I was good at this stuff.
[19:45] <Laurenceb> theoretically they can fly forever, but htey tend to meet tropical thunderstorms
[19:45] <Laurenceb> or polar icecaps
[19:45] <Laurenceb> IIRC the record is 90 days
[19:45] <Laurenceb> 5 circumnavigations
[19:45] Action: SpeedEvil hits Laurenceb with a plank constantly.
[19:46] <SpeedEvil> assymetrically up and down?
[19:46] <Laurenceb> yeah
[19:46] <Laurenceb> e.g. black bottom aluminised top
[19:46] <Laurenceb> in reality is more complex you use different polymeres and consider absorption cross sections
[19:46] <Cooleo-M> Hmm
[19:46] <Cooleo-M> Co2 rocket eh
[19:47] <SpeedEvil> Or even aluminised mylar top and bottom, and aluminium out on top
[19:47] <Laurenceb> problem is it has to cruise at 20Km or so
[19:48] <Laurenceb> and the lift is much lower thn helium, so you need a big envelope
[19:48] <SpeedEvil> What's the temp? +10C or so?
[19:49] <Laurenceb> yeah
[19:49] <Laurenceb> a bit more
[19:49] <Laurenceb> annoyingly the cnes site is down
[19:49] <Laurenceb> they had some good info
[19:49] <Laurenceb> but I estimated 10m diameter min
[19:50] <Laurenceb> using 15um polythene and mylar IIRC
[19:51] <edmoore> jcoxon: have the pics gone up?
[19:51] <Laurenceb> annoyingly I cant find a good database of polymer absorption cross sections
[19:51] <edmoore> the sstv ones
[19:51] <Laurenceb> they are on flickr
[19:52] <edmoore> link me up
[19:52] <Laurenceb> http://www.flickr.com/photos/jcoxon77/
[19:52] <SpeedEvil> Laurenceb: I remember a site. But I forgot it.
[19:53] <Laurenceb> I could probably use the fourier IR spectrometer of oxford
[19:53] <Laurenceb> *at
[19:54] <Laurenceb> seeing as I assembled it :D
[19:54] <SpeedEvil> OTOH.
[19:54] <Laurenceb> ?
[19:55] <SpeedEvil> IR thermometer will give you a ballpark guess.
[19:55] <SpeedEvil> At ~5um
[19:55] <Laurenceb> yeah

[19:55] <Cooleo-M> Ill just buy that
[19:55] <Cooleo-M> alot easier D:
[19:55] <Laurenceb> most of my work was on getting it to operate down to submillimeter range
[19:55] <SpeedEvil> rockets get _lots_ less piccys
[19:55] <Laurenceb> not sure it can go that high now

[20:02] <natrium42> what went wrong with the uploader?
[20:03] <jcoxon> its was more i didn't have a good enough data from the rtty
[20:03] <hallam> straight down, quite fast
[20:03] <jcoxon> as the shift was too little to distinguish
[20:03] <jcoxon> making a list of things to fix for the next flight
[20:04] <natrium42> ah
[20:04] <Cooleo-M> Heh, Its cheaper to do my balloon cluster than fire a rocket
[20:04] <natrium42> kite!
[20:05] <Cooleo-M> kite couldn't carry a camera could it?
[20:05] <fnoble> Cooleo-M, find a ladder, thats the easiest way to get photos from high up :)
[20:05] <hallam> sure it can
[20:06] <Cooleo-M> fnoble: Noo
[20:06] <hallam> perhaps a trebuchet
[20:06] <natrium42> Cooleo-M, they carry even heavy DSLRs
[20:06] <natrium42> look up KAP
[20:06] <natrium42> (kite aerial photography)
[20:06] <natrium42> hmm
[20:06] Action: Cooleo-M clicks
[20:07] <jcoxon> haha
[20:07] <jcoxon> nah
[20:07] <jcoxon> thats better
[20:07] <Cooleo-M> Freaking heck they can take a lot of weight
[20:08] <natrium42> indeed
[20:08] <natrium42> wind is powerful :)
[20:08] <Cooleo-M> :D
[20:08] <Cooleo-M> and im right next to the sea, SO lots of wind
[20:08] <natrium42> you don't want too much wind, but yeah :P
[20:08] <Cooleo-M> :D
[20:08] <Cooleo-M> I might just make my balloon cluster, Easier :D
[20:09] <Cooleo-M> use that circuit to set fire the string holding it
[20:09] <Cooleo-M> and it will drop and parachute down :D
[20:11] <edmoore> trying to learn morse is mentally taxing
[20:12] <hallam> but mental taxes are better than the other kind
[20:15] <Cooleo-M> :D
[20:16] <edmoore> the constant beeping and concentration on beeping does my head in
[20:16] <Cooleo-M> Haha.
[20:16] <Cooleo-M> edmoore: Watch TopGear o.0
[20:16] <edmoore> what's on?
[20:16] <Cooleo-M> Cars
[20:16] <natrium42> edmoore, and then you hear beeping all day, eh?
[20:16] <edmoore> silly question
[20:17] <Laurenceb> now theres a suprise
[20:19] <Cooleo-M> edmoore: Clarkson is about to get owned by a lorry
[20:20] <edmoore> i will iplayer it later
[20:20] <Cooleo-M> :D
[20:20] <Laurenceb> oh wow
[20:20] <Laurenceb> this is already famous
[20:22] <rjharrison> Laurenceb So I gather. You noticed where the GPS sold me down the river jcoxon was saying
[20:23] <Laurenceb> if you take the left just befor papworth, then theres a track on the right after the first couple of bends
[20:23] <Laurenceb> you dont hve to take the route through elsworth
[20:24] <Laurenceb> the tracking was very impressive
[20:25] <rjharrison> Well the internet connect timed out for a bit when I got lost
[20:25] <rjharrison> Dam GPS. Should just ignore it and go the way I know
[20:25] <rjharrison> M1 A57 A1
[20:25] <rjharrison> That was about all on the tracker
[20:25] <rjharrison> :D
[20:26] <Laurenceb> yeah
[20:26] <Laurenceb> use M1 then A14
[20:26] <rjharrison> Will do that when I come down to launch
[20:26] <rjharrison> Hopefully in about 4-6 weeks time
[20:27] <rjharrison> ICARUS 1 Launch 1 or launch 2 depending on who you ask and what you know :)
[20:36] <hallam> some launch numbers have decimal parts
[20:37] <Laurenceb> haha
[20:38] <edmoore> 1.hush
[20:40] <Laurenceb> ICARUSsqrt(PI)
[20:40] <hallam> Cooleo, I have an idea for your cutdown
[20:40] <hallam> I think a bit of Visco fuse wrapped around the string would work very well
[20:40] <Laurenceb> Visco?
[20:40] <hallam> very easy and cheap
[20:40] <hallam> google
[20:41] <Laurenceb> oh just a pyro fuse?
[20:41] <hallam> yeah
[20:42] <Cooleo-M> hallam: Sweeet...Whats Visco?.
[20:43] <Cooleo-M> Ah
[20:44] <Cooleo-M> Still stuck on the remote ignition part/
[20:45] <Max0> jcoxon: you about?
[20:45] <Cooleo-M> hallam: Also, You cant buy that in under 100ft bits it seems
[20:45] <hallam> it's a very well defined time delay though
[20:45] <hallam> you can buy it in 10m lengths
[20:45] <hallam> don't know about shorter
[20:46] <Cooleo-M> Hmm
[20:46] <Cooleo-M> Do I light it before I let the thing go?
[20:46] <Cooleo-M> Or ignite it in midair?
[20:49] <hallam> before you let it go
[20:50] <Cooleo-M> Wow, Thats even easier.
[20:51] <hallam> rjharrison: Could you tell me what the model or manufacturer of your 70cm yagi is? And did you get it from radioworld.co.uk?
[20:56] <Cooleo-M> hallam: How much would I need to light? 10m before it goes?
[20:57] <hallam> I don't know what the burn rate is, it's been 7+ years since I used it
[20:58] <hallam> I'm sure the Internet knows though
[20:58] <Cooleo-M> hallam: age restrictions on it?
[20:58] <hallam> if you have a lot of excess lift in your balloon, the time could be as short as a minute
[20:58] <hallam> I doubt there are any
[20:58] <hallam> I remember getting hold of some when I was 15 without any difficulty
[20:58] <Cooleo-M> k :)
[21:00] <Cooleo-M> hallam: http://www.ukvisco.com/catalog/product_info.php?cPath=21&products_id=31

[21:07] <rjharrison> Hi edmoore do you go to EARS
[21:07] <edmoore> stayed here in the end
[21:07] <rjharrison> Just up lading a few pics and vid from today
[21:08] <rjharrison> loading*
[21:08] <jcoxon> hey i'm back
[21:08] <jcoxon> Max0, hey
[21:09] <hallam> Thanks Robert
[21:09] <rjharrison> hallam Sorry about the delay sorting the pics and vid from today
[21:09] <edmoore> pfff
[21:09] <hallam> no worries :)
[21:10] <Laurenceb> rjharrison: you have in flight photos?
[21:11] <Max0> hey jcoxon
[21:11] <jcoxon> hey
[21:11] <Max0> how are you?
[21:11] <jcoxon> good thanks
[21:11] <Max0> do u remember me?
[21:11] <jcoxon> not off the top of my head :-s
[21:12] <Max0> hehe used to idel in here a while back..
[21:12] <jcoxon> oooo okay
[21:12] <Max0> anyways ive a quick question
[21:12] <Max0> i have a motorola wr850g router running open wrt
[21:12] <Max0> n i think ive bricked it...
[21:13] <jcoxon> ooooo okay
[21:13] <Max0> and on the forums etc they say use a serial cable....
[21:13] <Max0> i also have a nokia 5110 phone with a cable...
[21:13] <jcoxon> how bricked is bricked?
[21:13] <rjharrison> Laurenceb jcoxon has those
[21:13] <rjharrison> I have the data log
[21:14] <Laurenceb> ah
[21:14] <jcoxon> rjharrison, i've posted the log and kml
[21:14] <Max0> err well i think its ok just a fucked up network config file
[21:14] <Laurenceb> from the powershot?
[21:14] <jcoxon> oh that fixable
[21:14] <rjharrison> There are no pics
[21:14] <jcoxon> thats*
[21:14] <Max0> yuh i thought so..
[21:14] <rjharrison> Only sstv
[21:14] <jcoxon> heheh
[21:14] <jcoxon> let me find a link to a guide, one sec
[21:14] <Max0> ive had the soldering iron out today..
[21:14] <jcoxon> oh
[21:14] <Max0> but havnt had any joy with the serial port
[21:15] <jcoxon> basically when you boot the openwrt for about 3 seconds it uses its default setup and this is when you can reflash it
[21:15] <jcoxon> using tftp
[21:15] <rjharrison> jcoxon needs to sort it so it saves them and dloads them to the gumstix chdk doesn't allow to do a usb dload easily
[21:15] <Max0> i cant find the rounter on the network..
[21:16] <Max0> let me post u the post i put on the openwrt forum...
[21:16] <jcoxon> okay
[21:16] <Max0> http://forum.openwrt.org/viewtopic.php?id=17491
[21:17] <jcoxon> okay
[21:17] <jcoxon> what OS are you running right now? Windows?
[21:17] <hallam> edmoore / fnoble: Anything else we might want from radioworld?
[21:17] <edmoore> ic-7000
[21:17] <natrium42> ;)
[21:17] <jcoxon> hehe
[21:18] <Max0> linux
[21:18] <fnoble> hallam, dunno, does it come with a bnc cable?
[21:18] <jcoxon> Max0, okay
[21:19] <rjharrison> no you have to make one up
[21:20] <jcoxon> first set your eth0 to 192.168.10.2
[21:20] <jcoxon> then in a console run:
[21:20] <rjharrison> PL259 to BNC
[21:20] <jcoxon> ping -f 192.168.10.1
[21:20] <hallam> righty, ic-7000 and all their BNC cables
[21:20] <hallam> ordered
[21:20] <fnoble> hallam, then can you get some connectors from there?
[21:21] <hallam> :P
[21:21] <hallam> do we need connectors other than the PL259 to BNC?
[21:21] <fnoble> nope, dont think so
[21:21] <edmoore> we need something to connect the yagi to the line-in on the laptop
[21:21] <edmoore> like an ic-7000
[21:21] <rjharrison> haha
[21:21] <hallam> there's a second-hand one for 700GBP
[21:21] <rjharrison> Keep trying ed
[21:22] <hallam> that's a good line item on the CUSF expense report
[21:22] <rjharrison> There's a new one for the same :)
[21:22] <hallam> "BNC to Stereo adapter, model IC-7000"
[21:22] <edmoore> yeah - they're about £700 new
[21:22] <hallam> if you say it three more times I'll order it
[21:22] <edmoore> it
[21:22] Last message repeated 2 time(s).
[21:22] <hallam> and Iain will kill me
[21:22] <Laurenceb> hehe
[21:23] <Laurenceb> you could make do with a pcr1000
[21:23] <Max0> hehe jcoxon ive done that
[21:23] <hallam> we could make do with the yaesu we have
[21:23] <Laurenceb> I've been trying to get one on ebay for a while
[21:23] <Laurenceb> one went for £147 while I was out
[21:23] <jcoxon> Max0, no sucess, even when you reboot the router?
[21:24] <Max0> nope, i was playing with the ip address of the router, n i think i changed it from 192.168.* to 172.16.*
[21:25] <jcoxon> yeah but it still retains its default
[21:25] <Max0> but its 100% not on the network, no nmap scans or sniffing the network
[21:25] <jcoxon> hmmm then console through a serial port it is
[21:25] <hallam> rjharrison, do you think a right-angle PL259 connector or a straight one would be more useful?
[21:25] <jcoxon> basically you need to wire up a serial console, just rx, tx and gnd
[21:25] <Max0> yuh i tried today
[21:25] <jcoxon> but hte issue is that on the router their voltages are 3.3v so you can't directly attach it to a PC
[21:25] <Max0> o
[21:26] <Max0> :(
[21:26] <Max0> feck
[21:27] <hallam> if you tried plugging it in directly it may or may not have fried the router
[21:27] <hallam> or at least the serial port on the router
[21:27] <jcoxon> you mentioned a nokia cable?
[21:28] <Max0> yuh ive a nokia serial cable for a 5110
[21:28] <Laurenceb> si there a way to test if it still works?
[21:28] <Max0> so cut it in half n there are 4 wires
[21:28] <jcoxon> Max0, that'll have conversion circutry in it
[21:28] <rjharrison> PEGASUS VI pics on the ground http://www.flickr.com/photos/30721501@N05/sets/72157608600418615/show/with/2995998599/
[21:28] <hallam> rjharrison, the website says it's a type N connector.. is that the same as PL259?
[21:28] <Max0> ah sweet
[21:29] <Max0> im not getting anything through it tho
[21:29] <rjharrison> " secs let me have a look
[21:29] <rjharrison> 2
[21:29] <jcoxon> so you could cut that open, identify the rx,tx and gnd and solder that to the serial port
[21:29] <jcoxon> rjharrison, urgh, a slideshow
[21:29] <Max0> ive already cut it up ;)
[21:29] <hallam> cheers
[21:29] <rjharrison> oops
[21:29] <Max0> and soldered what i thought was the right wires to the serial
[21:29] <jcoxon> hehe
[21:29] <jcoxon> its fine
[21:30] <Max0> well ive solered 4 wires to the router
[21:30] <Laurenceb> nice
[21:30] <Laurenceb> love the landrover
[21:30] <jcoxon> Max0, what are you using to to read teh serial port?

[21:30] <hallam> james, there's a good one of you there looking very pensive
[21:30] <jcoxon> i was pensive :-D
[21:30] <hallam> okay, thanks
[21:30] <rjharrison> I liked that one too
[21:30] <jcoxon> Laurenceb, the landy was bad ass
[21:30] <rjharrison> Probably the best shot
[21:31] <rjharrison> Get CUSF to put one on the expenses list
[21:31] <rjharrison> :)
[21:31] <hallam> I hadn't realised how silly I look in that leather jacket
[21:31] <Max0> jcoxon: which wires did u use on the router?
[21:31] <Max0> eg which holes
[21:32] <Laurenceb> you look like a 1920s pilot
[21:33] <jcoxon> Max0, hmmm give me a sec i'll find a pic
[21:33] <Max0> k cheers
[21:34] <Laurenceb> not as bad as here http://www.srcf.ucam.org/cuspaceflight/nova1selected/target0.html

[21:34] <hallam> Hey Steve
[21:34] <RocketBoy> hi guys
[21:35] <hallam> Laurence, I'm a little disturbed by how quickly you had that link to hand
[21:35] <Laurenceb> hehe
[21:35] <Laurenceb> I have catagorized bookmarks
[21:36] <jcoxon> evening RocketBoy
[21:36] <RocketBoy> jcoxon:you got it back OK?
[21:36] <jcoxon> yup
[21:36] <jcoxon> all sorted
[21:36] <RocketBoy> bonser
[21:36] <jcoxon> payload all intact, data recovered
[21:37] <RocketBoy> great - any sstv pics up?
[21:37] <Laurenceb> jcoxon: why diditn you use the gsm module on the goliath?
[21:37] <jcoxon> http://www.pegasushabproject.org.uk/wiki/doku.php/missions:pegasus6
[21:37] <jcoxon> Laurenceb, it wasn't working, it was being tempremental
[21:37] <Laurenceb> sucks
[21:38] <jcoxon> Max0, haha, you are making me work hard finding these pics - i've found my whole website
[21:38] <Max0> ?
[21:38] <hallam> How was the rest of EARS?
[21:38] <jcoxon> Laurenceb, you mean on the flight today?
[21:38] <Max0> hehe yuh i had a look at your website
[21:38] <Max0> n couldnt find it but there where links to it which wherent links
[21:38] <Laurenceb> yeah
[21:39] <jcoxon> Laurenceb, i had a gm862 onboard
[21:39] <Laurenceb> sorry maybe I should have read the wiki more carefully
[21:39] <jcoxon> the goliath board isn't great - i didn't fly it today
[21:39] <Laurenceb> I see
[21:39] <jcoxon> the gpsstix is more suited
[21:40] <jcoxon> Max0, yeah the links were lost when i moved to the wiki system
[21:41] <jcoxon> Max0, http://www.pegasushabproject.org.uk/pegasus4/construction/P1010612.JPG
[21:41] <jcoxon> thats the serial port you want to be using
[21:41] <RocketBoy> awesome fireworks at EARS - I don't think I will hear again
[21:42] <jcoxon> haha
[21:42] <Max0> jcoxon: yuh thats the one ive used
[21:42] <RocketBoy> such a big blast that it set a car alarm off on a car the other side of the wood
[21:42] <Max0> o
[21:42] <Max0> o o - RX
[21:42] <Max0> GND - o o
[21:42] <Max0> o o

[21:42] <jcoxon> rx connect to tx and tx connected to rx?
[21:43] <Max0> tried both
[21:43] <hallam> wow, I'm sorry I decided to do work instead of going back ;)
[21:43] <Laurenceb> jcoxon: that looks disturbingly familiar
[21:43] <Max0> well i think i have...
[21:43] <Max0> http://www.nslu2-linux.org/wiki/HowTo/AddASerialPort
[21:44] <Max0> says blue and red are rx and tx so tried em both ways
[21:44] <jcoxon> and you've connected gnd?
[21:45] <Max0> yuh if gnd is black
[21:45] <jcoxon> :-)
[21:45] <Laurenceb> cant you power it up to see if its still alive?
[21:45] <Laurenceb> or has it already been reflashed
[21:48] <edmoore> someone is re-bricking their router?
[21:48] <jcoxon> yup
[21:49] <jcoxon> well not me
[21:49] <edmoore> RocketBoy: just picked up an iambic paddle off ebay
[21:49] <jcoxon> Max0, is
[21:49] <Max0> im trying to
[21:49] <Max0> ;)
[21:49] <Max0> im not getting any serial info
[21:49] <edmoore> I tried bricking a router once
[21:49] <edmoore> it worked
[21:49] <edmoore> (the bricking)
[21:49] <Laurenceb> lol
[21:49] <Laurenceb> save yourself the trouble use a real brick
[21:49] <edmoore> if you're unlucky the work afterwards. That means you have to keep it
[21:50] <edmoore> so you come up with other more creative ways of getting rid of it
[21:50] <edmoore> like using it as a balloon flight computer
[21:50] <edmoore> they work afterwards*
