[00:32] <rjharrison> It's 12.30 here
[00:32] <rjharrison> It keeps trying to correct my spellih
[00:32] <Darkside> lol
[00:32] <juxta> actually I've used an ipad, the first thing I noticed was how it always correctly capitalizes the names of apple products
[00:32] <rjharrison> Spelling
[00:33] <rjharrison> Yep it's laudable
[00:33] <rjharrison> Yep apple
[00:33] <rjharrison> Oh iPad
[00:33] <rjharrison> Hehe that was ipad
[00:33] <juxta> hhaha, it's even complimenting itself now

[00:34] <juxta> I have thought an ipad might work well in a balloon chase though - all my tracking is done on a pc in the boot which i control via remote deskop from a laptop in the front on wifi
[00:35] <rjharrison> Dan-
[00:35] <rjharrison> Hum i havent fot
[00:35] <juxta> no need for keyboard input, a tablet would work well I think
[00:35] <rjharrison> Hehe
[00:35] <Dan-K2VOL> nice, juxta
[00:35] <Dan-K2VOL> I use teamviewer a lot on ipad
[00:35] <rjharrison> Ill give up now

[00:43] <NigeyS> hey juxta, Darkside
[00:43] <Darkside> could you find something that will fit my payload?

[00:43] <juxta> sure
[00:43] <Darkside> arduino + shield, + small amplifier, ++ batteries
[00:43] <juxta> give me some dimensions
[00:43] <juxta> and I'll get a box
[00:43] <NigeyS> juxta, sorry im taking ages but i will get that diagram thingy to you asap
[00:43] <Darkside> something about the size of your payload will be fine i think
[00:43] <juxta> no worries
[00:44] <juxta> okay - I'll see what they have
[00:44] <NigeyS> i find buying a payload box an odd experience, .. paying for an empty box .. doesnt seem right does it lol
[00:45] <Darkside> how much are they?
[00:45] <NigeyS> i paid £6 for my EPS box on ebay ......
[00:45] <juxta> I forget exactly
[00:45] <juxta> perhaps $10

[15:18] <MrCraig> thanks :)
[15:22] <SpeedEvil> np
[15:22] <Laurenceb_> think i got the photodiode worked out - 400um core plastic fibre + max3660 gives a decent signal
[15:23] <SpeedEvil> :)
[15:23] <SpeedEvil> I forget - what's this for again - the 3d imager?
[15:23] <Laurenceb_> annoyingly i cant find 400um graded index plastic fibre
[15:23] <Laurenceb_> its for a portable spectrometer
[15:23] <SpeedEvil> ah
[15:23] <Laurenceb_> for scattering liquids
[15:24] Action: SpeedEvil just uses a watering can.
[15:24] <Laurenceb_> i need to measure phase/amplitude response over 100mhz to 1ghz
[15:24] <Laurenceb_> and the "sensor" head has to be really small
[15:24] <Laurenceb_> hence fibre to the head
[15:24] <SpeedEvil> And then deconvolve into a sort of inverse fourier transform to get you the structione of the liquid?
[15:24] <Laurenceb_> unfortunately the path lenghts are long and theres lots of attenuation
[15:25] <Laurenceb_> yes
[15:25] <SpeedEvil> Broadly similar to my ideas for a laser ranger in fact.
[15:25] <Laurenceb_> the problem is the sensor head is moving about relative to the base unit
[15:25] <SpeedEvil> Though totally different, and I'm only looking at amplitude.
[15:26] <Laurenceb_> so step index fibres introduce motion artifact into the path lenght
[15:26] <Laurenceb_> dunno how big an effect that is - specs on data rates through step index fibres were a lot higher than i expected
[15:27] <SpeedEvil> Motion artifact is to despeckle?
[15:27] <Laurenceb_> bigger effect is vibration of the sensor head, which causes speckle
[15:27] <Laurenceb_> speckle only really occurs at the sensor head
[15:27] <SpeedEvil> ah
[15:28] <Laurenceb_> i think it can be solved with lots of decoherent integration of amplitude/phase
[15:28] <Laurenceb_> not sure what that does to SNR tho ... it gets rather complex
[15:29] <Laurenceb_> optical coherence techniques are another way to do it

[16:19] <Laurenceb_> the funniest thing about reaction engines is the hideously over complex helium systems is apparently due to a patent dispute with BAE systems

[16:48] <NigeyS> "If the Big Bang was the start of everything, what came before it?"
[16:48] <NigeyS> what a silly silly question :@
[16:50] <MrCraig> and the answer might be, any fairy tale you care to dream up?
[16:51] <NigeyS> well it answers itself

[16:52] <NigeyS> before the big bang was .. nothing
[16:52] <NigeyS> big bang = beginning of time and space .. so how can anything be before that ?
[16:52] <MrCraig> yeah - I saw the lack of logic in the question.
[16:52] <NigeyS> surprise surprise its a question being asked by the vatican
[16:53] <NigeyS> they just want some scientist to say "before it was god" bleh bleh
[16:53] <MrCraig> then we should tell them "we'll answer your question when you answer this one, when are you going to give your decision on the extradition of wanted criminals from vatican city?"
[16:54] <NigeyS> haha good point, i dont mind religion, but please, dont try and combine it with science, it just doesnt work
[16:54] <MrCraig> even if the answer was "no we won't extradite them" at least we'd have an answer after 7 years of waiting, I think they've forgotten.
[16:55] <NigeyS> theyre good at selectively forgetting things, like they forget what they did to the astronomers who dared to suggest the churches answer to the orbit of the planets was WRONG! and we were not the center of the dam universe!
[16:56] <Hiena> SpeedEvil, the actuators not necessary to be servos. Due the design request lot of small control surface, they could be digital.
[16:57] <MrCraig> The church sure has a lot to answer for - to be honest, if they chose to decide that God kicked off the big bang, I have no problem with that. If they chose to tell me that evolution is part of gods method and plan, no problem there either. I don't believe these things but they can believe what they want - but before I'm willing to even engage them in the conversation I want them to take responsability for their action
[16:57] <MrCraig> piece said cos I could rant on this subject for hours :)
[16:58] <NigeyS> lol i agree, and yes. enough said, its a topic i care about alot and could easily debate this all night!
[16:59] <MrCraig> Our thoughts are with you Hitch. :o)

[17:14] <Dan-K2VOL> Lots of different rockets
[17:14] <NigeyS> yush :D there a shorter version but its poo! lol
[17:37] <Hiena> Well, guess my neighbor will never ask a piece from my junks. He asked me a scrapped fire extinguisher tank, which i modded as liquid rocket engine. I discarded it, due the nozzle was overcut and the flow was unstable. I used it as container for the part washer liquid (highly flamable), and he asked it for a sprayer tank. I handed it to him about two months ago, and as i remember, i warned him about the fumes. Now he tried to weld it.
[17:42] <NigeyS> eeek good luck welding that lol
[17:46] <Hiena> The wire fence caught it, and except the smoked shop, no harm was done.
[17:46] <NigeyS> lol oh dear
[17:50] <Hiena> Knowing my workshop mishaps i give him 4/10 doing this.
[17:54] <NigeyS> luckily i've not had any "mishaps" as of yet
[17:59] <Hiena> There will be, there will be... Building things on tight budget attract the mishaps.

[21:34] <Lunar_Lander> hello
[21:34] <Dan-K2VOL> Hola
[21:35] <MrCraig> if I'm transmitting the protocol documented on the wiki, and something goes wrong in the process, say a field comes back empty from the gps and so I fail to process it - is it safe to simply send the CRLF and start again on the next string?
[21:35] Zuph (~bradluyst@ joined #highaltitude.
[21:35] <MrCraig> hello Lunar_Lander
[21:36] <SpeedEvil> send a figure like X
[21:37] <fsphil> anything between strings will be ignored
[21:37] <SpeedEvil> or something that doesn't occur in the data
[21:38] <MrCraig> ok - so an 'X' is a good - oh darn I need to start over character? (I'd build and validate the string before sending but working in assembler so trying to minimize the graft.
[21:40] <Lunar_Lander> ok
[21:40] <Lunar_Lander> now
[21:41] <Lunar_Lander> I should probably download this to get ahead with my balloon right? http://www.ukhas.org.uk/projects:dl-fldigi
[21:50] <Lunar_Lander> and what is a good and cheap receiver?
[21:59] mattltm (~mattltm@ joined #highaltitude.

[21:59] <mattltm> Wow!
[21:59] <Lunar_Lander> it is one of these stall phases
[21:59] <Lunar_Lander> nothing really there to drive the project
[22:00] <Lunar_Lander> unless I get real help with using the NTX2
[22:00] <Dan-K2VOL> Lunar_Lander
[22:01] <Lunar_Lander> yes
[22:06] <Lunar_Lander> Dan?
[22:06] <Dan-K2VOL> Yes
[22:06] <Dan-K2VOL> Oh,
[22:06] <Dan-K2VOL> hate to hear you stuck
[22:07] <Dan-K2VOL> what are you stuck on
[22:07] <Dan-K2VOL> you can use any scanner radio to receive that frequency
[22:07] <Dan-K2VOL> Buy one on ebay cheap
[22:08] <Lunar_Lander> ok
[22:08] <Lunar_Lander> I am no ham, but I have started to look on what you need to become one
[22:08] <Dan-K2VOL> Hook that to a computer running DL-FLdigi
[22:08] <mattltm> Make sure it can recive USB.
[22:08] <Lunar_Lander> I found that the technical part of the exam is heavily based on second semester physics
[22:08] <Dan-K2VOL> the beginning license is dead easy here, and I would think so there too
[22:08] <mattltm> Most cheep scanners only recive FM/AM
[22:09] <Dan-K2VOL> Well, the NTX2 is not a sideband transmitter
[22:10] <fsphil> wow, the funcube dongles are out of stock already
[22:10] <Dan-K2VOL> damn
[22:11] <Lunar_Lander> OK
[22:11] <Lunar_Lander> now
[22:11] <Lunar_Lander> I got a friend who wanted to do the balloon with me
[22:11] <Dan-K2VOL> good you need many people
[22:11] <Lunar_Lander> because he had made a system to record sensor data on a SD card to put in his backpack for hanggliding
[22:11] <Lunar_Lander> now he seems to be very busy
[22:12] <Lunar_Lander> and I doubt that he has interest still
[22:13] <Dan-K2VOL> Well, then if it's just you, I wouldn't bother to make anything custom, you should just buy off the shelf stuff, unless you want to spend years
[22:13] <Lunar_Lander> yes
[22:14] <Dan-K2VOL> Get the sparkfun balloon flight data sensor board that has tons of sensors,
[22:14] <Dan-K2VOL> And just launch those two things
[22:15] <Dan-K2VOL> It's nice to get a first flight of SOMETHING before putting too much effort in to it
[22:15] <Lunar_Lander> yeah definately

[22:21] <Dan-K2VOL> Also will need this: http://www.sparkfun.com/products/9530
[22:21] <Lunar_Lander> and comes with 6 sensors
[22:21] <Dan-K2VOL> Which we are also using on speedball
[22:22] <Lunar_Lander> yeah
[22:22] <Lunar_Lander> so you connect the logger to the board?
[22:22] <Dan-K2VOL> Yes
[22:22] <Lunar_Lander> ah and then you put in an SD and it writes to the SD
[22:22] <Lunar_Lander> cool
[22:22] <Dan-K2VOL> Yep!
[22:23] <Zuph> It's a pain in the ass to get data back out of.
[22:23] <Dan-K2VOL> Haha
[22:23] <Zuph> fyi
[22:23] <Lunar_Lander> oh
[22:23] <Dan-K2VOL> Well, only if you're trying to read it back out mid-air to the microcontroller flight computer
[22:23] <Lunar_Lander> yeah
[22:23] <Zuph> yes. On the ground, it's super simple.
[22:23] <Dan-K2VOL> Which you shouldn't bother with at this point
[22:23] <Lunar_Lander> yeah
[22:23] <Zuph> In the air, it blows.
[22:23] <Lunar_Lander> on the ground you simply shove the SD into the PC right?
[22:24] <Zuph> yep
[22:24] <Dan-K2VOL> Hehe yep, and that's all we do all day long, write, then read from it in the air
[22:24] <Dan-K2VOL> It's our telemetry staging area
[22:24] <Lunar_Lander> yeah
[22:24] <Zuph> Also, at this point, I'm tempted to phrase things interestingly so Dan's computer will read them out loud. Reykjavik.

[23:42] <Lunar_Lander> :)

[23:47] <Lunar_Lander> wasn't the GPS deactivated for civil use once?
[23:47] <SpeedEvil> Lunar_Lander: Sort-of
[23:48] <Lunar_Lander> I think in the first gulf war
[23:48] <mattltm> http://news.bbc.co.uk/1/hi/world/asia-pacific/3302763.stm
[23:48] <SpeedEvil> Before 1996, it was intentioally dithered.
[23:48] <Lunar_Lander> ah
[23:48] <mattltm> From a while ago but well done :)
[23:48] <SpeedEvil> By around 300m.
[23:48] <SpeedEvil> However.
[23:48] <Lunar_Lander> yeah
[23:48] <SpeedEvil> With internet, and the right receiver, (or indeed communications) this dither drops out.
[23:48] <Lunar_Lander> mattltm sounds like Gerald Bull there
[23:49] <Lunar_Lander> I mean Bull in his Iraq days
[23:51] <mattltm> Well now we have alerted the NSA, I'm off to bed!
[23:51] <mattltm> Night all :)
[23:51] <Lunar_Lander> night
[23:51] <fsphil> g'night!
[23:51] mattltm (~mattltm@ left irc:
[23:51] <Lunar_Lander> interesting that this simpson guy wasn't arrested
[23:52] <NigeyS> is temp %li phil ? in the rtty string ?
[23:52] <fsphil> depends on the type of variable
[23:52] <fsphil> int, float?
[23:53] <NigeyS> int
[23:53] <fsphil> try just %i -- though I don't think it'll make any difference
[23:54] <NigeyS> oki
[23:54] <Lunar_Lander> the wiki says that COCOM ceased to exist in 1994
[23:54] <Lunar_Lander> but there is a successor, right?
[23:56] <NigeyS> hmm nope, its just spitting out 1026 and 2 .. thats def not my temp or lightlevel .. lol
[23:58] <fsphil> make sure you're actually calling the bit of code to read the sensors
[23:58] <NigeyS> yeah it is doing
[23:58] <NigeyS> temp0 = getTempdata(address0);
[23:58] <NigeyS> photocellReading = analogRead(photocellPin);
[23:59] <fsphil> how are you printing it?
[23:59] <NigeyS> trying to append it to the end of the gps string
