[10:36] yup, cardiff [10:37] CARDIFF [10:37] do you see captain jack running around? >_> [10:37] haha i have a few times, and used to work in a bar they did filimng for Dr Who in aswell.

[11:17] no doubt, normally happen when i buy new things for the telesope to, cloud for weeks on end :/ [11:17] But that just gives more time for tweaking. [11:18] 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] Cloud imagery.

[11:21] i bet, nothing like a nice orange glow lighting up the bedroom from the stretlamp 6 ft away :( [11:21] 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] Camping fee is to catch several rats, and to move a couple of tons of rock. [11:22] 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] 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] See edmoores attempt [11:22] oo [11:22] 'hobble' [11:23] unfortunately, it is quite utterly impossible to google, as people can't spell hubble [11:23] 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] err [11:23] habble I mean [11:23] He used a large kite-like-thing to kill spin. [11:23] And then active stabilisation. [11:24] Also - the balloons are ~15m dia [11:24] how big :o lol [11:24] So the spar gets to be quite flexy [11:24] when at altitude [11:25] The mass of the spar was a big problem unless going to 2kg ballons [11:25] In principle you could make a large CF boxwork spar very, very light. [11:26] I didn't get that far. The cost of two balloons and helium was getting beyond a hobby. [11:26] 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] flapping [11:26] oh i forgot to ask about that, what's the average cost for helium nowadays? [11:27] And needs a very stiff wing. [11:27] 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] yeah i guess, im picturing those shoulder height bottles from BOC [11:28] SpeedEvil - is this for high altitude or just to make it fly? [11:28] dunno about helium but their oxy bottles are dam heavy ! [11:28] GW8RAK: in principle just to make it fly. [11:29] Radio controlled? [11:29] GW8RAK: though it would also work at larger scales for flying at quite high altitude. [11:29] yes. [11:29] Also - hydrogen is an alternative. [11:29] sounds interesting [11:29] hydrogen balloon fires are not particularly scary. [11:29] :o hydrogen = explosive :| [11:29] you have a 1m diameter bonfire for 0.5s [11:29] lol [11:29] And actually quite difficult to achieve. [11:29] and then a burning balloon thrown randomly up to 10m. [11:30] That's if you don't start out with a balloon filled with air. [11:30] Don't do that. [11:30] GW8RAK, good point, the concentrations or O and H have to be perfect for explosion iirc [11:30] oh man [11:30] should try and make the perfect mix [11:30] However, I can just imagine talking about hydrogen and air cadets in the same sentence. [11:30] and then tther the balloon, raising it up high [11:30] 4-84% [11:30] lol [11:30] or just releasing it, and haveing a timer [11:30] so it blows up at 1km or something [11:30] It's a really high flammability range. [11:30] Or so. [11:31] But even getting 16% of air in a balloon you're filling from empty is a sign that you're utterly blind. [11:31] As a kid, I did electrolyse water and put the gas mixture into a bin bag and apply a match. [11:31] big boom or little wimper? [11:31] It made a satisfying bang [11:31] hehe [11:31] mrpulkrabek (~mrpulkrab@gprs-internet-ff0ad100-4.dhcp.inet.fi) left irc: [11:32] But it was quieter than the other explosives I was playing with, so didn't continue! [11:32] so if He can go say 100,000 ft .. what would H take you to ? [11:32] http://www.youtube.com/watch?v=cQvpK9cl0No [11:32] NigeySWales: 99000 [11:32] hmm [11:32] Above is a hydrogen weatehr balloon full of hydrogen being lit. [11:32] It's essentially boring. [11:32] oo [11:33] And doable with modest safety gear, and a fire extinguisher. [11:33] All the heat and energy goes straight up. People even walked away from the Hinddenburg fire. [11:33] the big german airship ? [11:34] Yes. IIRC most people were killed by falling hardware. [11:34] http://farm1.static.flickr.com/2/1362599_02bcdea730.jpg [11:34] crikey [11:34] aaaargh [11:34] lol [11:35] OH THE HUGE MANATEE [11:35] i was having a discussion the other day on where space oficially starts, isnt it 70,000 ft ? [11:35] Depends on who's defining it. [11:36] usaf [11:36] they have a plane that goes 65,000ft + and the pilot is in full spacesuit gear [11:36] There are oodles of different definitions, going from 'what you can do one orbit in the shuttle at' on down [11:36] I think the region from 65,000 to 325,00 is called Near Space. [11:36] ahhh got ya [11:37] IIRC ~80km is where you can do that - and ~55km is where the aero controls of the shuttle start to work [11:38] 55km.. sounds familiar yup [11:40] anyone used 1 of these? .. http://www.adafruit.com/index.php?main_page=product_info&cPath=17_21&products_id=98 [11:42] I've not ever done the arduino thing. [11:42] Always from scratch. [11:43] oh [11:43] 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] NigeySWales - remember with GPS, that some units do not operate above 18km/60,000 feet). [11:44] Upu (~Upu@ubn.upuaut.net) left irc: [11:44] 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] does the lassen iq use a ublox chipset? [11:44] 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] DanielRichman, i dont think so [11:44] ublox is known to work [11:45] i.e. you send a sequence of bytes using the uBlox binary protocol, and it makes it work above 10km [11:45] or whatever the limit is [11:45] oh, i got the lassen chip idea from the wiki [11:45] Upu (~Upu@ubn.upuaut.net) joined #highaltitude.

I think we are all happy to share our experiances so people can move forward rather than repeat the same mistkes. [15:17] amen to that, i think it's the lack of sharing and openness that stifles alot of beginners journeys into all kinds of projects.

[16:31] Action: SpeedEvil has been levitating Al foil with his induction cooker. [16:31] has anyone got anymore info on the pyrotechnic cutdown thats on the wiki ? [16:31] i use resistors [16:31] I vaguely recall discussion. [16:31] are induction cookers any good? I'm thinking of getting one instead of gas [16:31] I also favour resistors. [16:31] You get a resistor rated to 350C cheaply [16:32] yeah everything ive seen so far has been resistors until i saw this [16:32] wrap a nylon string round this, and it melts cleanly [16:32] russss: IMO - yes. [16:32] 350.. toasty! [16:33] russss: They have an efficiency of ~85% - so the kitchen does not get as hot. [16:33] russss: gas is ~50% efficient. [16:34] 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] I really like the 'oops-proofing'.

[18:22] hi all [18:27] 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] if you apply only power to the radio module, do you hear anything? [18:38] the ntx2 for example will produce a very strong carrier [18:41] jasonb_ (~jasonb@38.101.196.246) joined #highaltitude. [18:42] also are you sure it's 433mhz? [18:47] 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] ooooh I hear something! [18:53] incorrectly oriented the modue :-/ eeek [18:55] hmm... that might be an issue lol [18:55] lol - it's difficult to tell with this thing [18:56] 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] I'm not sure this module will give you the range you need [18:57] yeah - I bought it cos it was �3 or so and therefore good for experimenting [18:57] I'll buy another module for a propper payload. [18:59] it seems to generate an AM signal -- not sure if that means on/off or proper analogue am [18:59] aren't the ntx2 modules also very small strength too? [19:00] from what I'm hearing I'd guess at on/off [19:00] 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] there's a good click behind it [19:01] the trick with the ntx2 is being able to use very sensitive amateur receivers [19:02] and modulating in such a way that it appears as an rtty signal [19:02] I'm not good with the details, someone else could probably explain it better than me :) [19:03] *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] I have a similar radio about here somewhere too [19:03] and I found the same as you, mostly got just nois [19:03] +e [19:04] *nods - I'm gonna try the paired reciever to see if that cleans the signal and see how sensitive it is. [19:06] I suppose you could use these modules to make a CW beacon [19:06] what's that then? :-P [19:06] morse code :) [19:06] aaah lol [19:06] cool plan tho [19:08] it's pretty amazing how far these little 10mw modules can be received [19:12] try scanning around a bit, you should be able to receive a good strong signal even without an antenna [19:12] smea (~smealum@85-171-205-215.rev.numericable.fr) joined #highaltitude.
