[02:06] <Darkside> aaargh
[02:06] <Darkside> juxta:
[02:06] <Darkside> anything accomplished at adrians/
[02:06] <juxta> ah I ended up back at mine
[02:07] <juxta> rewiring the car for the DC suppy in the carputer
[02:07] <Darkside> ahh ok
[02:07] <juxta> plus put in strategically located anderson SB50's to hook up a 20A supply so I can run everything while the car is stopped for extended periods of time
[02:07] <Darkside> what flying on the next launch?
[02:07] <Darkside> fonna do a cutdown system?
[02:07] <juxta> next launch is video for lonely planet
[02:08] <Darkside> ahh
[02:08] <Darkside> any predictions yet?
[02:08] <Darkside> or too ealy
[02:08] <juxta> little early - we have upto nov 11
[02:08] <juxta> which is in the right area
[02:08] <juxta> but no telling what 13/14 will be like yet
[02:09] <juxta> it's aroundt he right time of year though
[02:09] <Darkside> so it will go east?
[02:09] <juxta> no more going into victoria for a while hopefully :)
[02:09] <Darkside> better for it to go east than west...
[02:09] <juxta> yeah, east to north east
[02:09] <juxta> heh, west is a no fly :P
[02:10] <Darkside> :P
[02:10] <Darkside> cutdown system?
[02:10] <juxta> maybe, we'll see what is ready in time
[02:10] <juxta> adrian wanted me to take his car
[02:10] <Darkside> cut it when its 5km inland :P
[02:10] <juxta> cause he wont be there
[02:10] <Darkside> looooool
[02:15] <Darkside> so you driving his tank?
[02:20] <juxta> nah
[02:20] <juxta> i turned it down
[02:20] <juxta> I dont wanna be responsible for that!
[02:21] <juxta> i'm thinking maybe i should put a 16v zenner diode across the supply to the caputer to cope with any high voltage transients
[02:21] <juxta> what do you think?

[09:10] <juxta> i've got one of these at the moment: http://cgi.ebay.com.au/13-8-Volt-10-Amp-DC-Power-Supply-/140431013052?pt=AU_Business_Industrial_Safety_Security2&hash=item20b25734bc
[09:10] <juxta> well, except it's 20A
[09:10] <Darkside> cool
[09:10] <juxta> it's pretty terrible
[09:11] <juxta> very poorly cooled, adrian's added a bunch of fans and it still gets really hot & smells worrying
[09:11] <juxta> plus the GND rail on it is about 20V above mains earth
[09:11] <juxta> makes for fun when trying to connect something like a monitor which is running on mains to the carputer running on that
[09:12] <Darkside> lo
[09:12] <Darkside> looool
[09:12] <Darkside> thats scary
[09:13] <juxta> not ideal
[09:14] <juxta> this is the sort of thing you have, right?
[09:14] <juxta> http://cgi.ebay.com.au/12V-13-8V-DC-12-Amp-Regulated-Switching-Power-Supply-/350408754137?pt=LH_DefaultDomain_0&hash=item5195fd43d9
[09:17] <Darkside> yup
[09:17] <Darkside> exactly that
[09:17] <Darkside> but 15A
[09:18] <juxta> i think I'll grab something like that - it would be nice to have something with a bit more ingress protection for fingers and 240VAC though
[09:18] <Darkside> haha
[09:18] <Darkside> i covered teh end with electrical tape
[09:19] <juxta> sounds like a good plan
[09:19] <juxta> goes it get very warm?
[09:19] <juxta> active cooling needed?
[09:19] <Darkside> nah
[09:19] <Darkside> well, i dont draw 15A continuous from it
[09:20] <Darkside> so i dont know about that
[09:20] <juxta> i think I'll mount it up by the inverter and amp there in the car
[09:20] <Darkside> heh
[09:20] <juxta> leave it permenantly in there, less chance of fingers & mains
[09:20] <Darkside> have a 12V rail in the car :)
[09:21] <juxta> yeah I think the manufacturer took care of that
[09:21] <Darkside> ahahaha
[09:21] <Darkside> true
[09:21] <Darkside> oh wait
[09:21] <Darkside> what are you using this for then?
[09:21] <Darkside> why do you need another 12v supply, from 240v?
[09:22] <juxta> when the car's stopped & we're getting ready at launch etc
[09:22] <juxta> plug it in
[09:22] <Darkside> good point
[09:22] <juxta> i mean it'll go a while on battery etc, but it's nice to be able to plug it in
[09:22] <Darkside> yeah
[09:22] <juxta> for $30 for a switchmode PSU it sounds reasonable
[09:23] <juxta> so long as it doesn't catch on fire in the hot boot
[09:23] <Darkside> haha
[09:23] <Darkside> yes i'd hope not...
[09:23] <Darkside> any conformation on the dates yet?
[09:24] <juxta> nothing yet
[09:24] <juxta> i better ring graham now actually

[10:34] <eroomde> good morning NigeySWales
[10:34] <NigeySWales> hey eroomde :)
[10:34] <NigeySWales> what awful weather today :(
[10:35] <eroomde> quite nice here
[10:35] <eroomde> though wouldn't mind bad weather as i'm stuck inside anyway
[10:35] <NigeySWales> rain, and lots of wind here lol
[10:36] <NigeySWales> sods law isnt it, nice weather = stuck in doors, bad weather = lots of erronds to run :(
[10:36] <eroomde> are you in Wales?
[10:36] <NigeySWales> yup, cardiff
[10:37] <Darkside> CARDIFF
[10:37] <Darkside> do you see captain jack running around? >_>
[10:37] <NigeySWales> haha i have a few times, and used to work in a bar they did filimng for Dr Who in aswell.
[10:38] <Darkside> haha
[10:38] <eroomde> well you get the bad weather first
[10:38] <eroomde> and the worst of it
[10:38] <NigeySWales> david tenant - very nice polite chap !
[10:38] <eroomde> so i guess we'll have some of it by the end of today
[10:38] <eroomde> (w. sussex)
[10:38] <NigeySWales> sending it to you for 4pm eroomde :P
[10:46] <eroomde> ta
[10:46] <eroomde> so are ypu interested in flying a hab?
[10:49] <NigeySWales> yup, very much so, i have a few hurdles, like, no clue on electronics, but ive ordered an arduino mega to get me started
[10:52] <eroomde> cool, well you've come to the right place
[10:52] <eroomde> we'll get you up to speed in no time
[10:52] <NigeySWales> indeed, this place and the wiki has been amazing, learnt alot in just 2 days!
[11:00] <GW8RAK> NigeySWales - hello from North Wales
[11:12] <NigeySWales> hey GW8RAK hows the weather? :P
[11:13] <GW8RAK> Nice and sunny up here. But too windy to cycle to work today. Raintoday.co.uk shows a nice shower over Cardiff

[11:14] <GW8RAK> Not today thanks!
[11:15] <NigeySWales> lol meanie :( ;p
[11:15] <GW8RAK> I'm sure you'll find HAB'ing to be quite entertaining and at times very frustrating.
[11:15] <GW8RAK> I've yet to launch and trhought I'd just got the software sorted, when I lost time from the dowload data.
[11:15] slothear1 (~Christine@pool-96-249-157-79.hrbgpa.fios.verizon.net) joined #highaltitude.
[11:15] <GW8RAK> So back tot he drawing board
[11:16] <NigeySWales> no doubt, i think its going to be like astronomy, lots of patients required and mostly reliant on mother nature!
[11:16] <NigeySWales> ah dam :(
[11:17] <GW8RAK> I'm sure that once we're ready to launch the weather will be against us for weeks.
[11:17] <NigeySWales> no doubt, normally happen when i buy new things for the telesope to, cloud for weeks on end :/
[11:17] <GW8RAK> But that just gives more time for tweaking.
[11:18] <GW8RAK> I keep promising myself a telescope, but never quite get around to it. Nice dark skies at home apart from East where the glow from Liverpool shows
[11:18] <SpeedEvil> Cloud imagery.
[11:18] <NigeySWales> the all important tweaks!

[11:18] <NigeySWales> id love dark skies, but cardiff is really bad :(
[11:19] <SpeedEvil> Up here it's so clear, I can see the milky way right in the middle of the day!
[11:19] <NigeySWales> :o
[11:19] Action: SpeedEvil unwraps and eats milky way.
[11:19] <NigeySWales> ive never seen it in the u.k !
[11:19] <GW8RAK> That's a bad pun.
[11:19] <NigeySWales> lol SpeedEvil
[11:20] <SpeedEvil> yeah. I did see it last night when putting the bins out.

[11:20] <GW8RAK> I'm so used to dark skies that staying in a town is quite unnerving. Much too bright at night.
[11:20] <SpeedEvil> yeah - it's wierd.
[11:21] <NigeySWales> i bet, nothing like a nice orange glow lighting up the bedroom from the stretlamp 6 ft away :(
[11:21] <SpeedEvil> It's not usually _very_ dark here - there is a pop 40k town 5 miles away.
[11:21] Action: NigeySWales camps in SpeedEvil's garden
[11:21] Upu (~Upu@ubn.upuaut.net) joined #highaltitude.
[11:22] <SpeedEvil> Camping fee is to catch several rats, and to move a couple of tons of rock.
[11:22] <GW8RAK> Living on top of a hill makes for good all round visibility, but stargazing is much colder than just a few hundred metres down the hill.
[11:22] <NigeySWales> i have been wondering how possible it would be to take a few long exposure images of the stars from a HAB, stability would be a huge issue
[11:22] <SpeedEvil> See edmoores attempt
[11:22] <NigeySWales> oo
[11:22] <SpeedEvil> 'hobble'
[11:23] <SpeedEvil> unfortunately, it is quite utterly impossible to google, as people can't spell hubble
[11:23] <GW8RAK> Payload spin would be the problem, but I did consider two balloons at each end of a spar with the camera mounted centrally on the spar looking up.
[11:23] <SpeedEvil> err
[11:23] <SpeedEvil> habble I mean
[11:23] <SpeedEvil> He used a large kite-like-thing to kill spin.
[11:23] <SpeedEvil> And then active stabilisation.
[11:24] <SpeedEvil> Also - the balloons are ~15m dia
[11:24] <NigeySWales> how big :o lol
[11:24] <SpeedEvil> So the spar gets to be quite flexy
[11:24] <SpeedEvil> when at altitude
[11:25] <GW8RAK> The mass of the spar was a big problem unless going to 2kg ballons
[11:25] <SpeedEvil> In principle you could make a large CF boxwork spar very, very light.
[11:26] <GW8RAK> I didn't get that far. The cost of two balloons and helium was getting beyond a hobby.
[11:26] <SpeedEvil> I'm currently wondering about how to make a fapping craft that goes at 2-5hz, with a stroke of 1m, which is quite a reasonable G
[11:26] <SpeedEvil> flapping
[11:26] <NigeySWales> oh i forgot to ask about that, what's the average cost for helium nowadays?
[11:27] <SpeedEvil> And needs a very stiff wing.
[11:27] <GW8RAK> It depends on the size of the bottle. Big bottles are cheaper and could do for 2 or 3 launches, but the size and weight of the bottle makes it difficult to move unless you have a van.
[11:27] <NigeySWales> yeah i guess, im picturing those shoulder height bottles from BOC
[11:28] <GW8RAK> SpeedEvil - is this for high altitude or just to make it fly?
[11:28] <NigeySWales> dunno about helium but their oxy bottles are dam heavy !
[11:28] <SpeedEvil> GW8RAK: in principle just to make it fly.
[11:29] <GW8RAK> Radio controlled?
[11:29] <SpeedEvil> GW8RAK: though it would also work at larger scales for flying at quite high altitude.
[11:29] <SpeedEvil> yes.
[11:29] <SpeedEvil> Also - hydrogen is an alternative.
[11:29] <NigeySWales> sounds interesting
[11:29] <SpeedEvil> hydrogen balloon fires are not particularly scary.
[11:29] <NigeySWales> :o hydrogen = explosive :|
[11:29] <SpeedEvil> you have a 1m diameter bonfire for 0.5s
[11:29] <NigeySWales> lol
[11:29] <GW8RAK> And actually quite difficult to achieve.
[11:29] <SpeedEvil> and then a burning balloon thrown randomly up to 10m.
[11:30] <SpeedEvil> That's if you don't start out with a balloon filled with air.
[11:30] <SpeedEvil> Don't do that.
[11:30] <NigeySWales> GW8RAK, good point, the concentrations or O and H have to be perfect for explosion iirc
[11:30] <Darkside> oh man
[11:30] <Darkside> should try and make the perfect mix
[11:30] <GW8RAK> However, I can just imagine talking about hydrogen and air cadets in the same sentence.
[11:30] <Darkside> and then tther the balloon, raising it up high
[11:30] <SpeedEvil> 4-84%
[11:30] <NigeySWales> lol
[11:30] <Darkside> or just releasing it, and haveing a timer
[11:30] <Darkside> so it blows up at 1km or something
[11:30] <SpeedEvil> It's a really high flammability range.
[11:30] <SpeedEvil> Or so.
[11:31] <SpeedEvil> But even getting 16% of air in a balloon you're filling from empty is a sign that you're utterly blind.
[11:31] <GW8RAK> As a kid, I did electrolyse water and put the gas mixture into a bin bag and apply a match.
[11:31] <NigeySWales> big boom or little wimper?
[11:31] <GW8RAK> It made a satisfying bang
[11:31] <NigeySWales> hehe
[11:31] mrpulkrabek (~mrpulkrab@gprs-internet-ff0ad100-4.dhcp.inet.fi) left irc:
[11:32] <GW8RAK> But it was quieter than the other explosives I was playing with, so didn't continue!
[11:32] <NigeySWales> so if He can go say 100,000 ft .. what would H take you to ?
[11:32] <SpeedEvil> http://www.youtube.com/watch?v=cQvpK9cl0No
[11:32] <SpeedEvil> NigeySWales: 99000
[11:32] <NigeySWales> hmm
[11:32] <SpeedEvil> Above is a hydrogen weatehr balloon full of hydrogen being lit.
[11:32] <SpeedEvil> It's essentially boring.
[11:32] <NigeySWales> oo
[11:33] <SpeedEvil> And doable with modest safety gear, and a fire extinguisher.
[11:33] <GW8RAK> All the heat and energy goes straight up. People even walked away from the Hinddenburg fire.
[11:33] <NigeySWales> the big german airship ?
[11:34] <GW8RAK> Yes. IIRC most people were killed by falling hardware.

[11:34] <NigeySWales> crikey
[11:34] <Darkside> aaaargh
[11:34] <Darkside> lol
[11:35] <Darkside> OH THE HUGE MANATEE
[11:35] <NigeySWales> i was having a discussion the other day on where space oficially starts, isnt it 70,000 ft ?
[11:35] <SpeedEvil> Depends on who's defining it.
[11:36] <NigeySWales> usaf
[11:36] <NigeySWales> they have a plane that goes 65,000ft + and the pilot is in full spacesuit gear
[11:36] <SpeedEvil> There are oodles of different definitions, going from 'what you can do one orbit in the shuttle at' on down
[11:36] <GW8RAK> I think the region from 65,000 to 325,00 is called Near Space.
[11:36] <NigeySWales> ahhh got ya
[11:37] <SpeedEvil> IIRC ~80km is where you can do that - and ~55km is where the aero controls of the shuttle start to work
[11:38] <NigeySWales> 55km.. sounds familiar yup
[11:40] <NigeySWales> anyone used 1 of these? .. http://www.adafruit.com/index.php?main_page=product_info&cPath=17_21&products_id=98
[11:42] <SpeedEvil> I've not ever done the arduino thing.

[11:43] <SpeedEvil> You noticed 'GPS shield for Arduino kit with data-logging capability. After building this easy kit, you can create your own geo-locative project. Please note that this shield does not come with a GPS module, they are sold separately (see below)'
[11:43] <GW8RAK> NigeySWales - remember with GPS, that some units do not operate above 18km/60,000 feet).

[11:44] <NigeySWales> yeah noticed that, im going for the laseen iq ? gps module which apparently needs a breakout board anyway as its so tiny to work with so thought as i want SD aswell i might try that
[11:44] <Darkside> does the lassen iq use a ublox chipset?
[11:44] <GW8RAK> There is also a speed limit, but you need a unit which will operate above the height limit but not the speed limit. Some prevent operation when either parameter is exceeded.
[11:44] <NigeySWales> DanielRichman, i dont think so
[11:44] <Darkside> ublox is known to work
[11:45] <Darkside> i.e. you send a sequence of bytes using the uBlox binary protocol, and it makes it work above 10km
[11:45] <Darkside> or whatever the limit is
[11:45] <NigeySWales> oh, i got the lassen chip idea from the wiki

[16:31] <NigeySWales> has anyone got anymore info on the pyrotechnic cutdown thats on the wiki ?
[16:31] <Laurenceb_> i use resistors
[16:31] <SpeedEvil> I vaguely recall discussion.
[16:31] <russssss> are induction cookers any good? I'm thinking of getting one instead of gas
[16:31] <SpeedEvil> I also favour resistors.
[16:31] <SpeedEvil> You get a resistor rated to 350C cheaply
[16:32] <NigeySWales> yeah everything ive seen so far has been resistors until i saw this
[16:32] <SpeedEvil> wrap a nylon string round this, and it melts cleanly
[16:32] <SpeedEvil> russss: IMO - yes.
[16:32] <NigeySWales> 350.. toasty!
[16:33] <SpeedEvil> russss: They have an efficiency of ~85% - so the kitchen does not get as hot.
[16:33] <SpeedEvil> russss: gas is ~50% efficient.
[16:34] <SpeedEvil> russss: So you can't simply compare burner wattage. You turn it on, and it's on, no wait time like 'normal' electric.
[16:34] <SpeedEvil> I really like the 'oops-proofing'.

[16:34] <SpeedEvil> I occasionally feel like shit.
[16:34] <SpeedEvil> The knowledge that it's practically impossible to burn the house down unless you're deep frying with one is reassuring.
[16:35] <SpeedEvil> And any burns you get from it will not be serious. Also it's pretty much 'wipe-clean', which is nice.
[16:36] <SpeedEvil> I just got (to repair the cooking surface top) a 4 place hob for 20 quid on ebay.

[18:22] <MrCraig> hi all
[18:27] <MrCraig> so - I got the pic chip working on it's internal oscillator and I'm running a program that very imaginatively flashes an LED :-) Now i've attached the led positive pin to the data pin of my radio module, tuned my radio to 433 and I hear nothing :-/
[18:38] <fsphil> if you apply only power to the radio module, do you hear anything?
[18:38] <fsphil> the ntx2 for example will produce a very strong carrier
[18:41] jasonb_ (~jasonb@38.101.196.246) joined #highaltitude.
[18:42] <fsphil> also are you sure it's 433mhz?
[18:47] <MrCraig> I'm certain it's a 433 as per the data sheet, but with power only hear nothing http://www.craigchapman.me.uk/files/vy48.pdf
[18:53] <MrCraig> ooooh I hear something!
[18:53] <MrCraig> incorrectly oriented the modue :-/ eeek
[18:55] <fsphil> hmm... that might be an issue lol
[18:55] <MrCraig> lol - it's difficult to tell with this thing
[18:56] <MrCraig> sounds very noisey though - and with more than a foot between the transmittter and reciever it starts to weaken - I guess I need good antennae
[18:56] <fsphil> I'm not sure this module will give you the range you need
[18:57] <MrCraig> yeah - I bought it cos it was £3 or so and therefore good for experimenting
[18:57] <MrCraig> I'll buy another module for a propper payload.
[18:59] <fsphil> it seems to generate an AM signal -- not sure if that means on/off or proper analogue am
[18:59] <MrCraig> aren't the ntx2 modules also very small strength too?
[19:00] <MrCraig> from what I'm hearing I'd guess at on/off
[19:00] <MrCraig> I hear a pulse in the white noise as the led flashes
[19:00] Gnea (~gnea@unaffiliated/gnea) left irc: Ping timeout: 240 seconds
[19:00] <MrCraig> there's a good click behind it
[19:01] <fsphil> the trick with the ntx2 is being able to use very sensitive amateur receivers
[19:02] <fsphil> and modulating in such a way that it appears as an rtty signal
[19:02] <fsphil> I'm not good with the details, someone else could probably explain it better than me :)
[19:03] <MrCraig> *nods - I am planning to follow what I've been finding on the wiki as closely as possible - hence buying a yaesu. I figure that going for trusted is a good start - but I do plan to switch for PIC's and like I said, bought this radio module because it was available and cheap.
[19:03] <fsphil> I have a similar radio about here somewhere too
[19:03] <fsphil> and I found the same as you, mostly got just nois
[19:03] <fsphil> +e
[19:04] <MrCraig> *nods - I'm gonna try the paired reciever to see if that cleans the signal and see how sensitive it is.
[19:06] <fsphil> I suppose you could use these modules to make a CW beacon
[19:06] <MrCraig> what's that then? :-P
[19:06] <fsphil> morse code :)
[19:06] <MrCraig> aaah lol
[19:06] <MrCraig> cool plan tho
[19:08] <fsphil> it's pretty amazing how far these little 10mw modules can be received
[19:12] <fsphil> try scanning around a bit, you should be able to receive a good strong signal even without an antenna

[21:44] <NigeySWales> its very hard to image it without blowing the core
[21:44] <fsphil> aye, the old classic :)
[21:44] <fsphil> I was really surprised how easy it was to get the colour
[21:44] <NigeySWales> that a single exposure or did you stack?
[21:44] <fsphil> single exposure
[21:45] <NigeySWales> wow, thats alot of detail and not to bad as far as field rotation goes, well done :D
[21:45] <fsphil> fairly quick if I remember - my scope isn't guided
[21:45] <fsphil> thanks
[21:46] <NigeySWales> id recommend for guiding a nice cheap 80mm refractor and a cheap autoguider from opticstar
[21:46] <fsphil> I'd like to get M31 some day but I never got anything more than a fuzzy spot
[21:46] <NigeySWales> haha m31 .. cardiff is so bad for LP i barely see even a faint wisp :(
[21:47] Action: russss would spend a fortune on astrophotography kit if he wasn't in London
[21:47] <fsphil> Not as bad as Cardiff here, yet ...
[21:47] <fsphil> that M42 shot was taken from my back garden
[21:47] <NigeySWales> snap russss i could spend 30k easily on a moderate setup :/
[21:48] <fsphil> although that was before they build a silly big shop right to the south of my house
[21:48] <fsphil> with silly big lights
[21:48] Action: earthshine_ is saving up for an AP Mach1GTO
[21:48] <NigeySWales> well i'm impressed, dark skies in the U.K are getting rarer and rarer :( after a few basic hab flights im going to try to get a few long exposure photos from space, it must be doable! lol
[21:49] <NigeySWales> lol fsphil i feel the pain, and earthshine_ no fair! the AP scopes are amazing quality!
[21:49] Nick change: earthshine_ -> earthshine
[21:49] <fsphil> lots of short exposures, and some way to detect the orientation and stack accordingly
[21:49] <fsphil> that'd be really neat
[21:49] <NigeySWales> yup, lots of 60second exposures and keeping it stable, weight could be an issue to
[21:50] <fsphil> not even 60 seconds ... sub-second exposures
[21:50] <russss> NigeySWales: it's doable, if you've got these guys' budget http://blastexperiment.info/
[21:50] <NigeySWales> true, imagine the clarity being above most of the muck in the atmosphere!
[21:51] <russss> I'm interested in stabilising a camera on a balloon payload but probably not to the extent you'd need to get a decent photo of space.
[21:51] <fsphil> some super-accurate accelerometers would be needed
[21:51] <NigeySWales> dam russss thats what you call expensive! lol
[21:51] <fsphil> although I suppose if there's a few bright reference stars, the images could be aligned on those
[21:52] <NigeySWales> yeah some form of star tracker
[21:52] <fsphil> ooh
[21:52] <NigeySWales> hmm got me thinking now! lol
[21:52] <fsphil> yea that would work
[21:52] <earthshine> could be done with adaptive optics
[21:53] <NigeySWales> scope wise, hell even an 80mm refractor and a meade dsi pro would work, not to heavy...
[21:53] <fsphil> it's keeping it intact after landing
[21:53] <NigeySWales> earthshine, i know some peeps with the sbig AO unit..
[21:53] Craig (~Craig@host86-161-28-83.range86-161.btcentralplus.com) left irc: Read error: Connection reset by peer
[21:54] <NigeySWales> yeah phil, thats 1 payload that would need a super soft landing, preferably nowhere near a powerline!
[21:55] <NigeySWales> earthshine, looking forward to playing with my arduino if it arrives tomorrow :D

[22:03] <SpeedEvil> accel are fairly not-very useful.
[22:03] <SpeedEvil> you want decent gyros
[22:04] <NigeySWales> i wouldnt know where to start with load stabalising with gyros.. definately a thought for a hab mission in the future though, maybe if i win the lottery :D
[22:12] <NigeySWales> couple of yaesu radios on ebay.. not cheap are they :o

[22:15] <NigeySWales> 817nd
[22:16] <Randomskk> they are cheap compared to some options :P
[22:16] <NigeySWales> 1 at 325 1 at 66 with 2 days left lol
[22:16] <Randomskk> they're also really good for HAB stuff due to battery and tiny size
[22:16] <jonsowman> that's not bad actually
[22:16] <Randomskk> it's about 400, 500 new?
[22:16] <jonsowman> £500
[22:16] <NigeySWales> think isaw 1 new for 500
[22:16] <jcoxon> evening all
[22:16] <NigeySWales> hey jcoxon :)
[22:16] Action: jcoxon has finished his oncall
[22:16] <Randomskk> hi jcoxon
[22:17] <Randomskk> we got a new notam :D
[22:17] <jonsowman> hi jcoxon
[22:17] <jcoxon> Randomskk, great
[22:17] <jonsowman> oh... Randomskk got there before me
[22:17] <jcoxon> so next sat...
[22:17] <jonsowman> :P
[22:17] <jonsowman> next sat is good
[22:17] <jcoxon> ummm i've locked myself out of nessie
[22:17] <Randomskk> how do you do that?
[22:17] <jcoxon> by keygen a new key for git
[22:18] <Randomskk> that cleared your old?
[22:18] <Randomskk> oops
[22:18] <Randomskk> wait, huh
[22:18] <jcoxon> must of
[22:18] <Randomskk> didn't you keygen on nessie though
[22:18] <jcoxon> yeah
[22:18] <jonsowman> that shouldn't change anything...?
[22:18] <jcoxon> "Permission denied (publickey).
[22:18] <jcoxon> "
[22:18] <jcoxon> well i can't get in...
[22:18] <jonsowman> paste me your pubkey
[22:19] <Randomskk> ah
[22:19] <Randomskk> I think it's that
[22:19] <Randomskk> ~jcoxon/.ssh is 777
[22:19] <Randomskk> dare I ask why
[22:19] <jonsowman> :o
[22:19] <Randomskk> reset it to 700
[22:19] <Randomskk> try now
[22:19] <jonsowman> that'd be why
[22:19] <jcoxon> yay
[22:19] <jcoxon> no idea why its 777
[22:20] <jcoxon> don't remember changing it!

[23:47] <Randomskk> NigeySWales: it's not bad. it cuts out at altitude though
[23:47] <Laurenceb> NigeySWales: Radio wise - ive got SDR working with a chipcon
[23:48] <Laurenceb> depends how far you want to delve into RF electronics
[23:48] <NigeySWales> okies cheers guys, was looking at getting the adafruit datalogger shield, wasnt sure what gps module to use
[23:48] <Laurenceb> but should be cheap
[23:49] <Laurenceb> we tend to avoid sirf3 tbh
[23:49] <NigeySWales> Laurenceb, something easy.. i was being a wuss using the 406a as i wouldnt have to worry about the power mismatch with the lassen chip
[23:50] <Laurenceb> im still unsure exactly how well it works in the real worrd - ie outside of matlab
[23:51] LazyLeopard (~irc-clien@chocky.demon.co.uk) left irc: Quit: Bye
[23:51] <NigeySWales> eek, you need a guinea pig hehe
[23:51] <Laurenceb> just need to retap some M3 holes for the enclosure then ive got a nice little box to take along to the next launch
[23:52] <Laurenceb> next weekend
[23:52] <Randomskk> you coming up to cambs?
[23:52] <Laurenceb> hopefully if all goes well
[23:52] <Randomskk> cool
[23:53] <Laurenceb> http://i.imgur.com/RAH0x.png <= ive got the pll stepping in little incriments now
[23:53] <Laurenceb> - see around 700
[23:53] <Randomskk> ooh nice
[23:54] <Laurenceb> but im rather busy with work, so prob no time to play with dcf77 or similar before next weekend
[23:55] <Laurenceb> ive got ~5cm square spare on some stripboard inside the enclosure to add something better clock wise
[23:56] <Laurenceb> probably going to use a crystal filter - nick crystals off a conrad module
[23:56] <Laurenceb> seems like cheating but its the simplest way

[23:57] <Laurenceb> the direct downconversion technique used by the guys on the epically long avrfreak thread is complex and hard
[23:58] <Laurenceb> if you dont get pure sine waves into the mixer and have a good mixer itll pick up the really strong long wave am stations around 77.5khz x n
[23:58] <Laurenceb> where n =2,3 etc
