[12:34] <jgrahamc> Interesting to hear more about the insurance situation as you find out.
[12:35] <GW8RAK> I have my doubts, but since rocketry payloads come down on a parachure, the risk is no greater for a balloon payload than a pointy rocket thing.

[12:58] <SpeedEvil> Afternoon indeed.
[12:58] <SpeedEvil> It is raining here.
[12:58] <SpeedEvil> So I'm smashing up my bathroom with a hammer.
[12:59] <Randomskk> as you do
[12:59] <SpeedEvil> Indeed.
[12:59] <SpeedEvil> making a small toilet + washbasin into a smallish wet-room + shower + toilet.
[13:00] <Randomskk> functionality++ I guess
[13:01] <SpeedEvil> Indeed.
[13:01] <SpeedEvil> I'm fixing this bathroom, so I can tear the other one out, and gt that entire side of the house.
[13:02] <Shuffty> Can anyone explain in brief what 'Neck Lift' is, or point me in the right direction as to where I can find out more info.
[13:03] <SpeedEvil> Neck lift is the amount of lift, measured at the neck.
[13:03] andrewallan (~andrewall@server.nowhere-else.org) left irc: Remote host closed the connection
[13:03] <SpeedEvil> A balloon with 1Kg neck lift can lift a bag of sugar tied to its neck.
[13:03] <SpeedEvil> A 1Kg bag of sugar.
[13:03] <SpeedEvil> 1Kg net.
[13:04] <Laurenceb_> mmm sugar
[13:04] Action: SpeedEvil wishes laptops could be run on sugar.
[13:04] <jgrahamc> I used a 1kg bag of sugar to test my parachute :-) http://blog.jgc.org/2011/03/gaga-1-parachute-test.html
[13:04] <Shuffty> That makes sense - so the amount a balloon can carry is determined by thesize of the balloon / gas & the max neck lift?? IS this right?
[13:05] <SpeedEvil> One sugarcube = 18Wh.
[13:06] <jonsowman> Shuffty: http://www.srcf.ucam.org/~cuspaceflight/calc/
[13:06] <SpeedEvil> Shuffty: Not 100% - you also have to take into account drag and desired ascent rate.
[13:06] <SpeedEvil> You need a given amount of extra gas (more or less) to make it ascend at a constant(ish) rate.
[13:06] <SpeedEvil> Over being 'balanced'
[13:07] <SpeedEvil> And yes, the calculartor is good.
[13:07] <Shuffty> Thanks jonsowman. will have a read of that.
[13:07] <jonsowman> Shuffty: have a play, it'll make things clearer :)
[13:07] <Randomskk> the neck lift value is more the thing you measure as you fill the balloon
[13:07] <Shuffty> SpeedEvil - what are the benefits of a lighter load
[13:07] <Randomskk> it's given because it's one of the easiest things to measure
[13:07] <Randomskk> but the basic concept is, the more gas you put into the balloon, the more lift you get
[13:08] <Randomskk> the more weight of payload, the less free lift you get
[13:08] <Randomskk> you need at least as much lift as payload weight, and then the extra lift goes to making it go up - the more free lift, the faster it'l go up
[13:08] <Randomskk> however there's a limit on how much gas you can put into a balloon, and the less you put in, the higher the balloon can go up before popping
[13:08] <Randomskk> (as the gas expands as you go up, so a very full balloon will not have much room for expansion and pop earlier)
[13:09] <Shuffty> Am I right in my presumption that the faster it goes up, the less distance it travels (winds not take into account).
[13:09] <SpeedEvil> Up to a limit - at the extremes, less gas seems to be contained by the balloon.
[13:09] <SpeedEvil> Shuffty: yes.
[13:09] <SpeedEvil> Shuffty: Even taking winds into account.
[13:09] <Randomskk> by and large, yes. it going up faster means it bursts sooner and then hits the ground sooner
[13:09] <Randomskk> so it spends less time in the air
[13:09] <Randomskk> and thus drifts less
[13:10] <SpeedEvil> There can be wierrdneses where that's not the case - if your balloon crosses a front into dramatically different conditions.
[13:10] <SpeedEvil> But generally not.
[13:10] <Shuffty> Thanks for all your help and input guys! Much appreciated! Still trying to get my head around everything! :-)
[13:10] <SpeedEvil> :)
[13:11] <Shuffty> I'm planning on releasing a balloon at some stage in the future - working on everything at the moment. My main concern ( and I'm sure I'm not alone) it loosing the payload to sea. Would rather sacrifice high a little.
[13:12] <Shuffty> high = height!
[13:12] <jonsowman> Shuffty: use the landing predictor, its pretty accurate
[13:12] <SpeedEvil> Where are you?
[13:12] <SpeedEvil> The landing predictor is awsome.
[13:12] <SpeedEvil> Can also be used for determining fallout from japan.
[13:13] <jonsowman> hehe
[13:13] <Shuffty> I've had a play with the landing predictor - very nice.
[13:13] <Shuffty> I'm in Manchester Speedevil.
[13:13] bhammet (~hellno@ left irc: Ping timeout: 276 seconds
[13:13] <Shuffty> How accurate is that landing predictor based on previous launches?
[13:14] <jonsowman> it gets more accurate the closer to launch time you run it
[13:14] <Randomskk> depends on how far in advance you run it, how good you are at getting the lift right, how accurate your payload mass is
[13:14] Action: Laurenceb_ tells Lewis Page about SpeedEvils fearmongering fallout comment
[13:14] <Randomskk> mostly it'l give you general direction accurately and in the few days beforehand you'll usually get within some tens of kms?
[13:14] <Randomskk> by the time the balloon's popped and is on the way down it can be very very accurate, km or less
[13:14] <Shuffty> Nice!
[13:15] <Randomskk> but that does depend on the above being accurate
[13:15] <jgrahamc> I asked jcoxon that question and his response was that a few days before you'll know the track along which the balloon will fly, but not where it will land precisely.
[13:15] <Randomskk> yea, that's about right
[13:15] <SpeedEvil> Especially handy is if you've got a live GPS, as you can sometimes get to where you can almost catch the balloon.
[13:15] <SpeedEvil> I don't think anyones actually caught one yet.
[13:15] <Randomskk> or have a picnic in the field it comes down in
[13:15] <jonsowman> I want to catch one
[13:16] <Randomskk> haha
[13:16] <jgrahamc> Catching it would be awesome.

[14:17] <NigeyS> the matter at the heart of a blackhole.. 0.004mm made up of quark degenerate matter.. see.. no need for a singularity!

[14:22] <NigeyS> although my idea might break down when applied to a supermassive black hole, it works for stellar mass, and so on, but much above, and it becomes a bit messy

[14:25] <NigeyS> nope, im doing a BSc in physical science, and im generally fairly thick, but i do have a keen interest in black holes
[14:25] <Laurenceb_> i think thats wrong
[14:25] <Laurenceb_> its cant be degenerate matter
[14:25] <Laurenceb_> but im a little rusty on degererate matter, sorry
[14:27] <NigeyS> that is an argument i've seen before, but as it stands, anything that rules out a singularity has at least a chance of being correct, einsteins classical cannot describe what's at the heart of a black hole, what i've come up with as as good as anything.
[14:27] <NigeyS> theory*
[14:27] <SpeedEvil> Now come up with a way in which itr makes a testable difference.
[14:27] <NigeyS> it's untestable :p
[14:27] <SpeedEvil> Otherwises, it's just masturbation.
[14:27] <Laurenceb_> i think you can show the degenerate matter will collapse
[14:27] <NigeyS> unless you want to jump into a bhlackhole for me? lol
[14:28] <Laurenceb_> Chandrasekhar mass limit iirc
[14:28] <SpeedEvil> Also - degenerate matter has way too high a density.
[14:28] <NigeyS> laurenceb from what i've read, the only thing that would positively state wether degenerate matter breaks down at the extremes of temp, and pressure is quantum gravity theory .. which mr hawkings is still working on !
[14:29] <SpeedEvil> Larger black holes would actually float in water.

[15:00] <Randomskk> sweet
[15:01] <andrewallan> the data format is a little non-standard so i'm hoping someone will write conversion code for that callsign on the server so that it can appear on spacenear.us
[15:02] <Randomskk> haha it is quite non standard
[15:02] <Randomskk> I've just finished up code that steals data from the old tracker and posts it to the new, beta system
[15:02] <Randomskk> so the next few flights will probably serve as something of a test. invisisbly to anything else, it doesn't affect current tracker operations

[15:04] <andrewallan> works well
[15:05] <Randomskk> got a launch date yet?
[15:05] <andrewallan> yeah we will email the mailing list before we launch
[15:05] <andrewallan> hopefully launching on Monday 4th April around 10am - depending on weather

[15:33] <andrewallan> like field 2 is milliseconds since power on, not a counter

[17:55] <fsphil> was quite neat -- they flew a plane over the site, and listened to the reflections from a normal radio transmitter

[18:04] <mattltm> The centre core of the coax has lifted the pad away from the pcb
[18:04] <fsphil> looks a bit messy

[18:10] grummund (~user@unaffiliated/grummund) joined #highaltitude.
[18:10] <MNSP> I drew same conclusion about IR fsphil and sonar is great if you're underwater. but what about on land or in the air, say for a drone?

[18:59] <mattltm> I was tempted by a 19 element yagi today.
[18:59] <MrCraig> an ebay spot?

[19:03] <MrCraig> not that I mind looking silly - actually, I was in geekdom driving around with the magnetic 4xwhip on the roof - I might attach it as a permanent ornament
[19:04] <mattltm> Looks like a tonna beam.

[20:47] <MNSP> hello all :)
[20:48] <mattltm> Hi MNSP
[20:48] <MNSP> any further thoughts on gps module?
[20:52] <mattltm> MNSP, does it have to be the Falcom?
[20:52] <MNSP> lol, no I meant your gps module that wasn't working, any thoughts on a fix?

[20:54] <mattltm> Ah! all fixed :)
[20:55] <MNSP> Excellent :)
[20:55] <MNSP> what was wrong with it?
[20:55] <mattltm> The GPS antenna?
[20:56] <mattltm> Someone had replaced the standard coax with some larger size rg58.
[20:56] <MNSP> yes
[20:57] <mattltm> I think the cable had flexed and the centre core had lifted the track from the pcb.
[20:57] <mattltm> I stripped out the coax, cleaned the pcb and installed some standard thin coax.

[20:58] <mattltm> cleaned off the end of the lifted track and bridged it across the centre coax.
[20:58] <MNSP> Cool and it all works
[20:58] <MNSP> ?
[20:58] <mattltm> Just installed in on top of my test payload and seems to be working good.

[21:02] <mattltm> Shuffty, Just seen your question form earlier...
[21:02] <mattltm> Yes, the project is going well.
[21:02] <Shuffty> Which one :-) I've asked a few today! lol
[21:03] <Shuffty> Ah - the HABAT question...
[21:03] jkominar (~justin@ left irc: Quit: It was a perfectly cromulent thing to do.
[21:03] <mattltm> <Shuffty> @mattltm Hows the HABAT coming along? Just been reading through your blog - it seems like a great idea!
[21:04] <mattltm> I have just finished building a simple payload that works the same as the standard type that everyone flies.
[21:04] <mattltm> So now I can start on the actual tracking system.
[21:05] <mattltm> I am hoping that the dl-fldigi team will build RPC into the program for the next release so that HABAT can pull the lat/long and alt straight from dl-fldigi.
[21:05] <Shuffty> What is the payload you've put together - arduino/gps/ntx2/etc?
[21:06] <Shuffty> Your blog makes for some good reading.
[21:06] <mattltm> Yup. Arduino Uno, Venus GPS, NTX2.
[21:06] <mattltm> Thanks. I think its a bit crap!
[21:06] <mattltm> lol
[21:06] <Shuffty> We all think current things are crap - but in 20 yrs time you'll look back on it with pride!
[21:07] <mattltm> lol.
[21:07] <Shuffty> Whats the venus gps like?
[21:08] <mattltm> Nice.
[21:08] <mattltm> Fast lock time.
[21:08] <Shuffty> http://www.coolcomponents.co.uk/catalog/product_info.php?products_id=518
[21:08] <Shuffty> that one?
[21:08] slothearn (~Christine@ joined #highaltitude.
[21:09] <mattltm> Yes. That's where it came from to. There was an altitude limit but the new firmware has solved that, maybe.
[21:09] <mattltm> Since my payload is not going up, it dosent matter.
[21:09] <mattltm> However, I hope that fsphil is going to fly it with one of his once I have finished using it for testing.
[21:10] <fsphil> indeedy
[21:10] <Shuffty> Am I right in thinking that the venus uses less power too??
[21:10] <mattltm> That way we can find out if it works.
[21:10] <mattltm> 28mA
[21:10] <Shuffty> Cant you short rant test it with a part balloon? :-)
[21:10] <mattltm> lol

[21:13] <MNSP> hi lunar_lander
[21:13] <mattltm> Newer version and it has 2 modes.
[21:13] <fsphil> Shuffty, yes there's been a few changes since those pictures where taken -- the rig control on the left mostly
[21:13] <Lunar_Lander> hi Shuffty
[21:13] <Shuffty> Hey Lunar_lander! :-)
[21:13] <fsphil> hiya lunar
[21:14] <Lunar_Lander> hi fsphil
[21:14] <Lunar_Lander> I got one for oyu
[21:14] <Lunar_Lander> *you
[21:14] <Lunar_Lander> one HAB flyer in America is Paul Verhage
[21:14] smeAWAY (~smealum@89-156-20-102.rev.numericable.fr) left irc: Ping timeout: 240 seconds
[21:14] <Lunar_Lander> and he wrote a 680 pg ebook on HAB, but you can see that it was written back in 2005
[21:14] <Lunar_Lander> because he writes "CCD digital cameras are still too expensive"
[21:14] <Lunar_Lander> and the sentence I like best
[21:14] <fsphil> haha
[21:15] <Lunar_Lander> "You need a lot of memory, so make sure to have an 64 MB (!) SD card"
[21:15] <fsphil> Huge!
[21:15] <Shuffty> lol :-)
[21:15] <Lunar_Lander> when I compare that to the USB stick I take to uni every day
[21:16] <Lunar_Lander> it is as big as an SD and houses 8 GB
[21:16] <Lunar_Lander> technology really progressed since 2005
[21:16] <Lunar_Lander> xD
[21:16] <MNSP> don't want to look stupid (again today) but aren't ccd digi cameras expensive still?
[21:16] bhammet (~hellno@ joined #highaltitude.
[21:17] <Lunar_Lander> I think when he wrote that, he had digital cameras in general in mind
[21:17] <MNSP> ah I see
[21:17] <Lunar_Lander> because the text then goes on on how to use 35 mm cameras
[21:17] <Lunar_Lander> btw
[21:17] <Lunar_Lander> what is "120 film"?
[21:17] <Lunar_Lander> he wrote about that as well
[21:17] <MNSP> iso??
[21:17] <MNSP> I think thats what that is
[21:18] <Shuffty> 120 film is a large format film - like 35 but bigger.... for medium format cameras...
[21:18] <Lunar_Lander> ah
[21:18] <Shuffty> Was it a sarcastic question .. :-)
[21:18] <Lunar_Lander> no, because I had thought
[21:18] <Lunar_Lander> is 120 like 120mm?
[21:18] <Shuffty> :-)
[21:18] <Shuffty> yes
[21:18] <fsphil> the canon A560 has a CCD sensor
[21:18] <MNSP> live and learn
[21:18] <Lunar_Lander> he only writes that 120 makes better pictures but is more expensive
[21:19] <MNSP> balls!!! I went and got an a480

[21:19] <MNSP> WooHoo
[21:20] <MNSP> cake in the post
[21:20] <fsphil> well so wikipedia says ,, and it *never* lies
[21:20] <MNSP> lol
[21:20] <Lunar_Lander> wait
[21:20] <Lunar_Lander> why is the normal 35 mm film called "135"?
[21:20] <Lunar_Lander> so 120 is like 20 mm?
[21:21] <russss> 120 is actually ~55mm wide, IIRC
[21:21] <russss> it doesn't refer to the size
[21:21] <russss> it's just an arbitrary number
[21:22] <russss> there's 220 film too, which is the same size as 120 but longer
[21:22] <Lunar_Lander> ah ok
[21:22] <Lunar_Lander> and 16 mm is common for movies right?
[21:22] <Lunar_Lander> or was common

[21:55] <Hibby> seeing as I've got all this strathab stuff done, I might be doing my own in summer. Thinking about an sstv link :
[21:55] <Hibby> :)
[21:55] <fsphil> the video's been APOD'ed
[21:58] <fsphil> sstv from a balloon is neat
[21:58] <Hibby> biggest issue is getting a suitable camera, im thinking
[21:59] <Hibby> equally, though, if all goes well I've have 2 months in the US in summer
[22:00] <fsphil> there are uart cameras, that return a small jpeg image
[22:00] <fsphil> or smaller raw images
[22:00] <MNSP> oh yeah? small raw images?
[22:01] <fsphil> 160x120 :)
[22:01] <Hibby> sweet
[22:01] <Hibby> then it's a case of understanding how sstv works and implementing it in software
[22:02] <Hibby> I'm half tempted to do everything in python on a bifferboard
[22:03] <Randomskk> o/
[22:03] <Hibby> hola
[22:03] <Randomskk> python is obviously the way forward for everything
[22:04] <fsphil> noooo
[22:12] <Lunar_Lander> fsphil btw
[22:12] <Lunar_Lander> how do you do SSTV when you are not allowed to use ham frequencies?
[22:12] MNSP (Mit@cpc1-lutn3-0-0-cust700.9-3.cable.virginmedia.com) left irc: Read error: Connection reset by peer
[22:12] <fsphil> same way we do rtty -- with the license free module
[22:14] <fsphil> sstv is an FM signal -- brighter parts have a higher frequency than darker bits (or the other way around, not sure)
[22:15] <fsphil> so with the NTX2 you just vary the voltage with the the right timing
[22:15] <fsphil> -the
[22:15] <Lunar_Lander> ah
[22:19] <Lunar_Lander> can this be done like
[22:19] <Lunar_Lander> that the GPS data comes down and also (from time to time) a picture?
[22:20] <fsphil> yes - just instead of a varying voltage, just use two
[22:21] <Hibby> Or you could if you've got the power, overlay gps data on the picture
[22:21] <fsphil> memory too
[22:21] <Hibby> aye
[22:21] <Lunar_Lander> ah

[22:23] <Lunar_Lander> with the 64 MB SD card
[22:23] <Hibby> another reason I want to bifferboard it :)
[22:23] <Hibby> that and the usb support
[22:23] <SpeedEvil> No.
[22:23] <SpeedEvil> I wish someone'd do a linuxuino.
[22:24] <Hibby> SpeedEvil: what features would you want?
[22:24] <SpeedEvil> Say 8M ROM (or SD boot) 8M RAM (more would be nice) lots of GPIO, reasonable power consumption, bifferboardish or cheaper price.
[22:24] <Lunar_Lander> SpeedEvil that PDF book by Verhage about HABing suggests using a 64 MB SD for capturing all photos xD
[22:24] <Lunar_Lander> (the book was written in 2005)
[22:25] <SpeedEvil> :)
[22:25] <Hibby> fair game
[22:26] <SpeedEvil> I just came across the invoice for my firstr 386/20 PC.
[22:26] <SpeedEvil> Insane price.
[22:28] <LazyLeopard> ...especially when you adjust currency values for inflation. ;)
[22:28] <SpeedEvil> yeah.
[22:28] <SpeedEvil> It's like 5 grand in current money
[22:29] Action: SpeedEvil wonders if it's actually possible to buy a 5 grand 'normal' PC.
[22:29] <SpeedEvil> Where normal does not include something like a 100TB raid, and 40" monitors.
[22:30] <Lunar_Lander> yeah
[22:30] <Lunar_Lander> I think for that money you get one of those "gamer" machines + casemod today
[22:30] <Lunar_Lander> or
[22:30] <Lunar_Lander> about 10 normal PCs
[22:30] <SpeedEvil> Sure.
[22:30] <Lunar_Lander> :P
[22:31] <SpeedEvil> You can bling it up with stupid overclocking, and hacked together piles of GPUs.
[22:31] <Hibby> can do that for well less than 5k though
[22:31] <SpeedEvil> True.
[22:32] <SpeedEvil> This is part of the reason I hate the 'we will use more resources forever' people.
[22:32] <SpeedEvil> I ask them to guess how many candles they'd need per year to light their home to their current levels.

[22:44] <Shuffty> :-)
[22:45] <Lunar_Lander> 17.25
[22:45] <Lunar_Lander> that is lambda/4 for the 434 MHz
[22:45] <Shuffty> in any design / layout ?
[22:46] <Randomskk> hang on, photo

[22:47] <Randomskk> five ~16cm wires
[22:47] <Randomskk> four go to the ground connection and spread out radially, perpendicular to the driven wire and on a plane
[22:47] <Randomskk> the driven one goes through the middle without touching them and points down
[22:48] <Randomskk> colourful plastic straws give +6dB power
[22:48] <Lunar_Lander> wait

[22:49] <fsphil> lol
[22:49] <fsphil> I'm going to KFC this weekend to get a straw. no other reason ;)
[22:49] <Shuffty> Fabulous - just what I wanted. Thankyou!
[22:49] <Shuffty> :-)
[22:50] <Hibby> Randomskk: I'm planning on doing something similar in design for the strathab lot in their next launches
[22:50] <Randomskk> Hibby: it works really well and is also really simple, win:win?
[22:51] <fsphil> will be interesting to compare the signal quality
[22:51] <Randomskk> it has a basically ideal radiation pattern for HAB - almost all downwards with main lobes roughly where you want for max range to listeners
[22:51] <Randomskk> physically is a really easy size, simple to construct
[22:51] <fsphil> the best reception I've had here was one of rjharrison's launches, and it was that style of antenna
[22:51] <Randomskk> and even perpendicular as I've drawn is near enough 50 ohms
[22:51] <fsphil> that and alien
[22:52] <Randomskk> actually the ground plane radials should be at like 45 degrees to the horizontal. or even more? to give 50 ohms
[22:52] <Randomskk> but it's not like it matters in practise
[22:52] <fsphil> just make sure the main element doesn't fall off :p
[22:54] <Randomskk> :P
[22:55] <fsphil> see that's what I did wrong last time - no straw
[22:55] <Randomskk> people think I'm joking
[22:57] <fsphil> I don't :) I'm pretty certain it would have worked better with it, would have kept it ridged. I think all the flopping about's what killed it
[22:57] <Hibby> Randomskk: do you use the plastic coating of the conductor to insulate it from the metal plate?
[22:58] <Randomskk> yes
[22:58] <Randomskk> in that case
[22:58] <Randomskk> I have seen much better antennas constructed from a coax cable plug
[22:59] <Randomskk> you can solder your coax from the radio to one end
[22:59] <Randomskk> and on the other, instead of plugging into something you solder your driven element to the middle and radials around the edge
[22:59] <Randomskk> the one on flickr there was a very quick hack job :P
[22:59] <Shuffty> :-)
[23:00] <SpeedEvil> In some ways, it's not so important.
[23:00] <SpeedEvil> In most cases, the signal is not lost because of insufficient antenna gain.
[23:00] <Randomskk> indeed
[23:01] <SpeedEvil> It's lost because the payload went behind terrain.
[23:01] <SpeedEvil> 3 or even 6dB isn't going to make a difference.
[23:01] <Hibby> the strathab antenna was a wire dipole I threw together as they gave me so little notice of their launch, so it wasn't ideal
[23:01] <SpeedEvil> It makes a difference for people at rextreme range.
[23:02] n900evil (~Speedevil@tor/regular/SpeedEvil) left irc: Ping timeout: 276 seconds
[23:03] <fsphil> which isn't really a priority unless you're flying long distance
[23:04] <Hibby> aye, but we're pretty far north of most listeners available
[23:04] <SpeedEvil> And for people at extreme distance, it's generally not important, as they are at best fun to have confirm it.
[23:04] <fsphil> Hibby, was that dipole set horizontally or vertically
[23:04] <Hibby> for the next launch I'm going to try and get the local ARSes involved
[23:05] <fsphil> I'd get out my yagi but all these launches are during the week when I'm at work
[23:05] <SpeedEvil> Because at extreme range, the curvature of the earth cuts them off well before landing, so predictions made as the payload falls past 10km with no info under it aren't that ideally useful.
[23:05] <Hibby> fsphil: Horizontally, I think. I left it up to them to decide. Not my best move, but not my project and I was grumpy with them at that point.
[23:05] <fsphil> lol
[23:05] <fsphil> how many teams are there?
[23:07] <Hibby> 3 in total. 2 consisting of purely mech engineering students, whom I've been drafted in to assist, and 1 of Electrical/Mechanical Eng degree students, who've been pretty awesome, but the task is suited to the cross disciplinary nature of their degree
[23:08] <Hibby> also, I'm biased towards them as that's my degree
[23:09] <Hibby> :p
[23:09] <fsphil> so we'll be expecting good things from them ;-)
[23:10] <Shuffty> Randomskk - for the aerial you described earlier, is there a specific wire / gauge?
[23:10] <Hibby> they're the ones with the website I posted the other day
[23:10] <Randomskk> Shuffty: not really. we just used some wire.
[23:10] <Hibby> trying out a zepp antenna with them, will be curious to see how it goes - test launch on Monday/Wednesday from what I hear
[23:11] <fsphil> excellent
[23:11] <Shuffty> Where are they launching from?
[23:12] <Hibby> Cumnock, Ayrshire, Scotland
[23:12] <Hibby> I'll be about to use my station too
[23:12] <Hibby> http://personal.strath.ac.uk/james.tosh/ <== relevant website
[23:12] <Hibby> they're the cause of all this unusual data strings chat on the mailing list
[23:14] <Shuffty> :-)
[23:15] <Shuffty> I have a feeling I wont be able to track that one - a little too far away! :-)
[23:15] <SpeedEvil> Quite close to me, but I have no radio.
[23:15] <SpeedEvil> Well - none that'll do 433.
[23:15] n900evil (~Speedevil@tor/regular/SpeedEvil) joined #highaltitude.
[23:15] <Shuffty> My radio arrives in the morning.. :-)
[23:18] <Hibby> 'sall good. I should be able to use the satellite station, seeing as I run the thing, and can clock the day in as "productive low-power testing of satellite station"

[23:33] <Lunar_Lander> yeah Hibby
[23:33] <Lunar_Lander> always good to write stuff like that in the lab book :D
[23:35] <Lunar_Lander> I actually began one because of feynman
[23:35] <Lunar_Lander> he said that he never wrote down what he did in his home lab when he was a kid and that he thinks that this was not good
[23:36] <SpeedEvil> If you're feynman.
[23:37] <Lunar_Lander> well I'm not him
[23:37] <Lunar_Lander> but I have so many balloon ideas as well
[23:37] <Lunar_Lander> and I don't want to run the risk forgetting a good one
[23:43] <n900evil> Ideas are cheap IMO.
[23:43] <n900evil> Got way too many.
[23:45] <Lunar_Lander> yeah
[23:45] <Lunar_Lander> btw
[23:45] <Lunar_Lander> our good public TV here has a kid's channel
[23:45] <Lunar_Lander> and they now made a "digital future" serial
[23:45] <Lunar_Lander> which is like trivial to the tenth power
[23:46] <Lunar_Lander> because the protagonist is some kid with huge earphones with yellow pads and a spiral wire (and he has those earphones around his neck all the time, even in an episode where he gets out of bed in the middle of the night)
[23:46] Action: n900evil remebers Tomorrows World.
[23:47] <Lunar_Lander> yeah
[23:47] <Lunar_Lander> but as far as I got it, TW was far more advanced
[23:47] <Lunar_Lander> here they say
[23:47] <Lunar_Lander> "First, log in at the video platform"
[23:47] <Lunar_Lander> and you can see that they are on youtube, only with the logos removed
[23:47] <n900evil> There is nothing like it in the UK now. (TW)
[23:48] <Lunar_Lander> besides, that kid has three desks, with two screens on the one side and one on the opposite
[23:48] <Lunar_Lander> (in one episode he makes a clip called "Lord of the Nerds")
[23:48] <Lunar_Lander> *facepalm*
[23:49] <n900evil> Well - http://www.bbc.co.uk/podcasts/series/material
[23:49] <Lunar_Lander> yeah
[23:49] <Lunar_Lander> best is
[23:50] <Lunar_Lander> that third screen is connected to a laptop on the other table
[23:50] <Lunar_Lander> so he types into the laptop and has to look 90° to the leftr
[23:50] <Lunar_Lander> -r
[23:50] <Lunar_Lander> only an idiot would setup his PC like that
[23:50] <Lunar_Lander> thanks for the link n900evil
[23:55] <SpeedEvil> I do actually have my keyboard and screen at 90 degrees, coincidentally.
[23:55] <SpeedEvil> But I'm lying down with the keyboard on my lap, and the screen is to my right.
[23:57] <Lunar_Lander> ah
[23:57] <Lunar_Lander> actualyl
[23:57] <Lunar_Lander> *actually
[23:57] <Lunar_Lander> that guy has a keyboard in front of the screen as well
[23:58] <Lunar_Lander> but when he is typing, he types into that laptop
[23:59] <SpeedEvil> Sigh.
