[00:00] <rjmunro> Party balloons can stay inflated for several days at ground level - how long is it expected to stay aloft?
[00:00] <fsphil> last I heard it was heading east
[00:01] <fsphil> so probably out to the north sea
[00:01] <fsphil> nobody knows if it will float, that's what they want to test
[00:02] <fsphil> but yea it could float for days :D

[00:14] <NigeyS> phil
[00:14] <fsphil> yo
[00:14] <NigeyS> theyre testing the new near-ir telescope right now, having the images sent to me, frikkin awsome!
[00:15] <fsphil> what are they imaging?
[00:16] <NigeyS> ill upload now
[00:17] <NigeyS> www.nigey.co.uk/astro/lastimage2.jpg
[00:17] <NigeyS> thats only a 30second exposure :o
[00:17] <SpeedEvil> neat
[00:17] <SpeedEvil> What's the FOV?
[00:17] <NigeyS> let me check
[00:18] <NigeyS> 16x16 arc minutes
[00:18] <NigeyS> http://wiki.global-rent-a-scope.com/GetFile.aspx?File=GRAS_Telescopes/IRDK20_14.JPG
[00:19] <fsphil> this is the best I've got of the nebula: http://www.sanslogic.co.uk/images/astrophotography/orion-nebula-1-2007-02-03.jpeg
[00:19] <NigeyS> not bad dude!
[00:19] <NigeyS> its very hard to image as the core gets over exposed so easily
[00:19] <fsphil> I was well chuffed :)
[00:20] <fsphil> the stars are doubled though, the scope wobbled during the exposure
[00:20] <fsphil> that was ages ago, I must try again
[00:20] <fsphil> not being able to focus properly put me off astrophotography
[00:20] <SpeedEvil> That is good
[00:21] <NigeyS> AP is tricky, so many variables
[00:21] <fsphil> the camera I have doesn't have live preview, so focus is a guessing game
[00:21] <NigeyS> everything has to be just right, optics, seeing, transparency, weather, preferably no moon, mount trackin, post processing..etc
[00:22] <fsphil> have you used one of these?: http://en.wikipedia.org/wiki/Bahtinov_mask
[00:22] <NigeyS> phil i use a nikon d60 at home, and i get the same problem, can be a right arse
[00:22] <NigeyS> not yet, but some people i know swear by them
[00:27] <NigeyS> mailto:?body=http%3A%2F%2Fwww.facebook.com%2Falbum.php%3Faid%3D47083%26id%3D1072598775%26l%3D09dedd9994&subject=Astro Pics

[00:28] <NigeyS> a few more pics in there phil
[00:28] <fsphil> gorgeous shot of M81
[00:30] <NigeyS> lovely aint she, and thats just 1 exposure
[00:30] <fsphil> single exposure or stacked?
[00:30] <NigeyS> that m94 image was an arse mind, just didnt come out right at all :/
[00:30] <NigeyS> single
[00:30] <fsphil> oh it says right there
[00:30] <NigeyS> hehe
[00:31] <NigeyS> you should sign up for the free trial at gras, something to do on cloudy nights
[00:31] <fsphil> definitely
[00:31] <fsphil> are you using an equatorial mount?
[00:31] <NigeyS> and that moon pic, was just the htc hero held to the 8inch scope eyepiece .. tricky to do but what a shot! lol
[00:32] <NigeyS> yeah, theyre the best for AP, if you use alt-az you need a wedge
[00:33] <SpeedEvil> My lunar photography tops out at a camera jammed into binoculars.
[00:33] <SpeedEvil> :)
[00:33] <SpeedEvil> I should try stacking with the n900 again
[00:34] <NigeyS> if it works.. :D .. be surprised just what you see in binos mind!
[00:34] <NigeyS> m31 easily if in a dark enough site
[00:34] <SpeedEvil> That does work
[00:34] <SpeedEvil> The camera + binocs
[00:34] <SpeedEvil> clamped well
[00:34] <NigeyS> Genius :D !!
[00:34] <SpeedEvil> They also work great for beam expanders for laser pointers
[00:35] <NigeyS> haha yes, watch out for the planes mind..lol
[00:35] <SpeedEvil> With a convenient second scope to pick up the bounce
[00:35] <fsphil> My attempt at M31 just shows a blurry spot :)

[09:48] <fsphil_> morning jcoxon, all still go?
[09:48] <jcoxon> yeah i think so
[09:48] <jcoxon> weather is very wet
[09:49] <LazyLeopard> Aye, 'orrible soggy here, too..
[09:50] <jcoxon> i hoping that we can fill undercover
[09:50] <fsphil_> clear skys here, hopefully heading your way too
[09:50] <jcoxon> then we just walk it out and let go
[09:50] <jcoxon> as the balloon is mini
[09:50] <Randomskk> hopefully so
[09:50] <Randomskk> cued at 11 still?
[09:51] <jcoxon> 11:30
[09:51] <jonsowman> 11.30
[09:51] <jonsowman> :)
[09:51] <Randomskk> cool
[09:51] <jcoxon> need to pop into b and q on the way and grab some foiled bubble wrap
[09:52] <jcoxon> as i've got foam but need something a bit more waterproof
[09:53] <jcoxon> jonsowman, i was think - we could fill under the covered bit when you leave the bar
[09:53] <jonsowman> that's an idea
[09:54] <jonsowman> should be fine
[09:54] <jcoxon> and then walk it out
[09:54] <jcoxon> the only wet bit is getting the tank there
[09:54] <jonsowman> hehe
[09:54] <jonsowman> i'm sure we'll manage
[09:55] <jcoxon> hehe lets hope so
[09:55] <jcoxon> so here is the challenge - the fill hole on the balloon is quite small
[09:55] <jcoxon> we'll need to craft an adapter
[09:56] <jcoxon> i've brought some tubing that fits the balloon
[09:56] <jcoxon> then we could just use the normal filling tube but with some tape
[09:56] <jcoxon> to the little tube
[09:56] <jcoxon> also would reduce the pressure when filling
[09:56] <Randomskk> there is not much tape won't solve
[09:56] <jonsowman> that sounds like it'll work
[09:57] <jonsowman> just need to careful with the cylinder valve
[09:58] <jcoxon> yeah

[11:00] <NigeyS> hey SpeedEvil
[11:01] <fsphil_> I mean 300km distance, from a payload 5km up :)
[11:03] <Darkside> fsphil_: i need to modify the darkside payload xml file
[11:03] <Darkside> where can i go to get the xml, so i can modify it and send it to people to upload or something
[11:04] <jonsowman> http://robertharrison.org/listen/darkside.xml
[11:04] <jonsowman> i assume that's what you mean?

[11:05] <jonsowman> hi NigeyS
[11:05] <NigeyS> how's things mr ?
[11:05] <jonsowman> fine thank you, yourself?

[11:17] <Darkside> also battery voltage
[11:17] <juxta> you mean on the tracker Darkside?
[11:17] <Darkside> yeah
[11:17] <Darkside> i.e. what do i put in teh xml to display this
[11:17] <fsphil_> you need a field of type: <dbfield>temp_int</dbfield>
[11:17] <juxta> that's not in the XML as such
[11:18] <Darkside> fsphil_: ok got that
[11:18] <Darkside> and data type is fine as integer?
[11:18] <fsphil_> decimal
[11:18] <Darkside> ok
[11:18] <Darkside> is there a list of what things it will ccept somewhere?
[11:18] <Darkside> i ssume you have a launch to deal with :P
[11:19] <fsphil_> I don't think there's a list, the best place is probably to compare with the other payload xmls
[11:19] <Darkside> ok
[11:19] <juxta> fsphil_, the fields that get displayed on the tracker are hardcoded per payload

[11:23] <fsphil_> ahh, I thought it pulled it in from the xml
[11:24] <fsphil_> so what's the xml for if it's not used by the tracker?
[11:24] <juxta> uh it's a bit hodgepodge really, the result of stuff being built on over the years I guess
[11:25] <juxta> the XML does define the format for the payloads
[11:25] <juxta> but it doesnt for example define the field names in the tracker
[11:26] <fsphil_> so before a launch, someone has to go into the tracker and say... field 8 is temperature, 9 is latitude... and so on
[11:28] <juxta> well it's defined per-payload

[14:00] <jcoxon> Colin_, partially as we have no idea what altitude it'll burst/float at
[14:01] Action: Colin_ nods - I guess if they pop at different alts it will do interesting things
[14:01] <fsphil_> if they pop at all
[14:01] <Colin_> true
[14:02] <Laurenceb__> how did you seal them?
[14:03] <fsphil_> about 10km from the launch site now
[14:03] <jcoxon> eek - sweepstake on float altitude
[14:04] <fsphil_> 5.5km
[14:04] <Darkside> shiiiiit, hope this still isnt floating in 10 hours or so..
[14:04] <Colin_> Darkside: why
[14:04] <fsphil_> the map can handle it :)
[14:04] <Darkside> because we're launching then
[14:04] <Darkside> haha
[14:05] <AlanWB5RMG> jcoxon - what alt are you aiming for ?
[14:05] <Colin_> the tracker handle more than one
[14:05] <fsphil_> slowing down again
[14:05] <jcoxon> AlanWB5RMG, no idea
[14:05] <Darkside> fsphil_: its more the shitloads of data coming in whenever you load spacenear.us thats the problem
[14:05] <jcoxon> the higher the better
[14:05] Action: Laurenceb__ guesses 1.4Km
[14:05] Action: Colin_ guesses 2.2km
[14:05] <fsphil_> good point Darkside
[14:06] <fsphil_> add a filter to the tracker? something like http://spacenear.us/tracker/pico
[14:06] <Darkside> wont work for tomorrows payloads :P
[14:06] <Darkside> since theres gonna be 2 payloads transmitting
[14:06] <fsphil_> aah more htan one
[14:06] <AlanWB5RMG> the WhiteStar team refers to a narrow band of jet sream for their trans-Atl float alt,
[14:06] <Darkside> yes we have a UHF and a VHF payload
[14:07] <juxta> jcoxon, do predictions put it turning around and heading out to sea?
[14:07] <jcoxon> yes
[14:07] <jcoxon> if it gets high enough :-p
[14:07] <juxta> hehe
[14:08] <AlanWB5RMG> but, that jet stream alt probably varies somewhat... /;^)
[14:08] <juxta> any guesses on altitude jcoxon?
[14:09] <Futurity> lol just checked http://spacenear.us/tracker/
[14:09] <Futurity> and its practically over my house
[14:10] <fsphil_> quick, release the secret weapon!!
[14:10] <Futurity> lol
[14:10] <Futurity> shame i'm working and not at home
[14:10] <NigeyS> lol
[14:10] <fsphil_> drat, foiled again!
[14:11] <NigeyS> Futurity, go and blow it a bit so it heads west :D
[14:11] <Futurity> may have got a full decoded packet ;)
[14:11] <juxta> fsphil, Futurity - what's the current freq?
[14:12] <jcoxon> really beginning to slow
[14:12] <jcoxon> not good
[14:12] <Futurity> I'm not receiving as at work

[14:14] <Graham_G3VZV> shift still around 460Hz
[14:14] <jcoxon> probably best not go that way
[14:15] <juxta> asc rate is still moving around a bit, perhaps it's just caught in winds
[14:15] <Elwell> freq shift is due to temp on modules?
[14:15] <NigeyS> speeding up again a bit
[14:15] <juxta> Elwell, yes
[14:15] <jcoxon> yeah the module is very exposed
[14:15] <juxta> does this one have the crystal oven running jcoxon?
[14:16] <LazyLeopard> Air-cooled, even?
[14:16] <jcoxon> juxta, no
[14:16] <jcoxon> its air-cooled
[14:16] <jcoxon> very air-cooled
[14:16] <NigeyS> its naked!

[14:18] <juxta> maybe at the landing site
[14:18] <NigeyS> haha brill !
[14:18] <chembrow> jcoxon how much He did you use compared to a normal launch, was it significantly less?
[14:18] <jcoxon> chembrow, yes

[14:20] <jcoxon> eek
[14:20] <juxta> what's in Luton?
[14:20] <jcoxon> its going down
[14:20] <eroomde> that's where they tale terrorists who hijeack aeroplanes
[14:20] <eroomde> they divert them to luton
[14:20] <NigeyS> an airport for 1 :|

[14:21] <davejay> It heading toward my house lol
[14:21] <fsphil_> prepare the secret weapon again!
[14:21] <NigeyS> parcel it up and send it back to james :p
[14:21] <Laurenceb__> seems to be more or less floating
[14:22] <fsphil_> there goes my 5.5km guess
[14:22] <juxta> hmm, rising again now
[14:22] <NigeyS> its done a right angle turn .. fun
[14:22] <Elwell> who's G3VZV-FCD?
[14:22] <Graham_G3VZV> we could be tracking it for days...what is the expect battery life James?
[14:22] <eroomde> james says 20ish hrs
[14:22] <Elwell> ah, I guess Graham :-)
[14:22] <Graham_G3VZV> Elwell, Graham g3VZV using a FUNcube SDR dongle
[14:22] <Laurenceb__> 2Ah lipo iirc
[14:22] <jcoxon> Graham_G3VZV, over 20hrs
[14:22] <fsphil_> how's the funcube doing?
[14:23] <Elwell> Graham_G3VZV: same Q as ^^ :-)
[14:23] <Laurenceb__> ooh funcube
[14:23] <Elwell> saw the -fcd and wondered :-)
[14:23] <Laurenceb__> can anyone do harmonic rejection tests on the funcube?
[14:23] <Graham_G3VZV> dongle is doing fine - the satellite s nearing final engineering model stage so we are going all out to book/buy a launch later this eyar
[14:23] Action: Elwell still needs to make up some cables
[14:23] <NigeyS> i know where the balloons headed .. Newmarket races!
[14:23] <Laurenceb__> buy a launch ?!
[14:24] <Laurenceb__> who is paying?

[14:25] <Elwell> I'd have probably done more with my fcd if the damn Qt app didn't keep segfaulting
[14:25] <Laurenceb__> how much roughly will it cost?
[14:25] <LazyLeopard> ...and the ebay of dongle #200 is at 285 quid with five and a half days to go...
[14:25] <Laurenceb__> im guessing piggyback on another payload
[14:25] <NigeyS> heh jcoxon i might be coming back to cambridge..lol
[14:25] <NigeyS> it*
[14:26] <Graham_G3VZV> Laurenceb, the launch - prob about 50k euros..
[14:26] <Laurenceb__> wow
[14:26] <NigeyS> 50k :o what you launching, a bar of gold ?!
[14:26] <Laurenceb__> thats crazy cheap
[14:26] <chembrow> Graham_G3VZV have you got a web site with any info on it?
[14:27] <juxta> NigeyS, I'd say that's a rocket
[14:27] <NigeyS> sounds like, 50k though .. wow serious money
[14:27] <Laurenceb__> NigeyS: for a freaking satellite thats kind of cheap
[14:27] <Graham_G3VZV> try www.funcube.org.uk and wwww.funcubedongle.com
[14:27] <Elwell> strikes me as cheap

[14:31] <Laurenceb__> Graham_G3VZV: I looked at the feasibility of such a device a year or so ago, and found that harmonics in the LO kind of screwed it

[14:34] <jcoxon> yeah it won't
[14:35] <jcoxon> but to save batteries and all
[14:35] <jcoxon> at 1600 it'll revert back
[14:36] <LazyLeopard> It flew directly oer Duxford..
[14:36] <Laurenceb__> its based on time, or altitude?
[14:37] <jcoxon> Laurenceb__, time
[14:37] <SpeedEvil> how long do you hope for the batteries to last?
[14:37] <SpeedEvil> Does it go into a slow mode on the ground?
[14:37] <jcoxon> i tested with an old lipo and it did over 20hrs

[15:16] <Colin_> don't know, main telemetry is on 70cms
[15:17] <m1x10> fsphil: I guess the gps is working normally and I didnt damaged it: http://imagebin.org/133058
[15:18] <fsphil_> there's no 868mhz module this time
[15:18] <fsphil_> too risky
[15:18] <AlanWB5RMG> that alt is starting to level off nicely - looks good /;^)
[15:19] <Colin_> yup, it's pretty close to my 2.2Km guess
[15:19] <Colin_> Ah, we have a tracker to the east of the Balloon
[15:20] <adambro> ok re 868 mhz. I don't have a receiver for SSB on 70cms unfortunately
[15:20] <NigeyS> -0.4ms hmmm
[15:21] <NigeyS> burst already? :|
[15:21] <Colin_> steady downwards trend now
[15:21] <Colin_> maybe it opened one of the seals a bit and it's leaking
[15:21] <Colin_> be nice if it did come down, would save a wet landing
[15:21] <AlanWB5RMG> maybe one of the birthday candles burnt out ?

[15:22] <LazyLeopard> Hmmm... Descending...
[15:23] <AlanWB5RMG> when I was a kid, in the 60s - we'd take a dry-cleaning bag, balsa spreaders at the base, with birthday candles...
[15:23] <SpeedEvil> Are all the balloons required to get positive lift?
[15:23] <m1x10> fsphil: http://imagebin.org/133060 :)
[15:23] <Colin_> SpeedEvil: they had to add a couple at the last min - so maybe
[15:24] <AlanWB5RMG> we would hang strips of Al foil to try to get on the radar at the airport.. /;^)
[15:24] <NigeyS> lol alan
[15:25] <Colin_> AlanWB5RMG: it's a silver mylar balloon it probably shows up quite nicely except that the de-clutter software will delete it
[15:27] <Colin_> coming down faster now - it must be losing gas
[15:27] Action: SpeedEvil imagines a duck resting on top of the payload.
[15:27] <chembrow> so no float then
[15:27] <g7leu> any recommendations for mac software that's able to decode the telemetry?
[15:28] <radicalbiscuit> dl-fldigi
[15:28] <Colin_> fl-digi?
[15:28] <Laurenceb__> need a better way to seal the envelopes i guess
[15:29] <NigeyS> think its gonna be a splashdown
[15:29] <Colin_> it will be close - but the direction will change again as it gets lower
[15:29] <g7leu> thanks re fldigi
[15:30] <LazyLeopard> At what altitude did it get into the eastward airstream? At some point it should drop back into that southward one...
[15:30] <Colin_> g7leu: if you actually want to send telemetry to update the tracker you need the dl- version
[15:30] <LazyLeopard> ...at about 1400m, it seems.
[15:30] <chembrow> what did the payload weigh in at in the end? anyone know?

[15:33] <SpeedEvil> The duck got off.
[15:33] Action: Colin_ high 5's SpeedEvil
[15:33] <chembrow> is it likely that this is more sensitive to thermals etc... due to the lower lift?
[15:33] <Colin_> could be
[15:33] <LazyLeopard> Weird. ;)
[15:33] <SpeedEvil> also thermals happen more lower down
[15:33] <NigeyS> chembrow, about 80grams i think
[15:33] <SpeedEvil> usually payloads are going up at 5m/s or soish
[15:33] <SpeedEvil> at 2.5km
[15:33] <Colin_> SpeedEvil: it's only at about 10,000 feet - lots of thermals there

[15:34] <Colin_> I think it's most likely solar heating it probably went behind a cloud. The sky is quite patchy here atm
[15:35] <Colin_> which means it will probably come down at sunset
[15:35] <LazyLeopard> Hmmm... Sunset's in about an hour...
[15:36] <Elwell> hope you packed your canoe if you want to get payload back.
[15:36] <AlanWB5RMG> better start paddlin now /;^)
[15:36] <SpeedEvil> Rain even
[15:37] <AlanWB5RMG> ice ?
[15:37] <Graham_G3VZV> oh it just qsyed a kilohetrz or so
[15:38] <russss> this is a pretty cool flight
[15:38] <AlanWB5RMG> that was a pretty steady drop rate, my bet would be shade/rain effect, now back in the sun
[15:38] <LazyLeopard> Was that a sudden frequency change, or did I just knock something?
[15:38] <AlanWB5RMG> no insulation, right - that may account for freq shift as well
[15:39] RocketBoy (~steverand@212.183.128.9) left irc: Ping timeout: 255 seconds
[15:40] <Graham_G3VZV> no it was a very sudden shift up in frequnecy the best part of 1kHz. Not a gradual thermal effect

[15:42] <Laurenceb__> condensation on the pcb?
[15:42] <jonsowman> how's it going guys
[15:42] <Laurenceb__> might also explain the decrease in altitude
[15:43] <LazyLeopard> Frequency's quite ragged now.
[15:43] <AlanWB5RMG> ice on the pcb ? WB8ELK swears by his small-cell bubble wrap for insulation.
[15:44] <g7leu> fldigi installed. what mode should i use (sorry, new to this stuff)
[15:44] <x-f> bubble wrap wouldn't explode in higher altitudes?
[15:45] <LazyLeopard> Not at the 2km or so it's at now...
[15:45] <radicalbiscuit> does anyone know if any online receivers (like those at globaltuners.com) are able to pick this up? I haven't been able to find anything yet
[15:45] <Randomskk> radicalbiscuit: they have been used successfully in the past
[15:45] <radicalbiscuit> right. Wasn't sure if anyone was using one now
[15:46] <AlanWB5RMG> x-f, the larger cell variety can, the tiny bubbles havent shown that problem

[16:03] <radicalbiscuit> g8khw i mean
[16:03] <eroomde> yeah there were two big party balloons which made it only just not neutrally bouyany, and two garish smaller happy birthday party balloons which made it positive
[16:03] <g7leu> colin: not turning green.
[16:03] <Colin_> at this rate it will be the Felixtowe pilot boat that catches it
[16:03] <fsphil_> red?
[16:03] <eroomde> and one of the small ones going would be enough for it to slowly start descending
[16:03] <g7leu> not changing colour
[16:04] <fsphil_> are you in HAB mode?
[16:04] <russss> speed over ground seems to have slowed though
[16:04] <Colin_> g7leu did you start it with -HAB ?
[16:04] <russss> (can the tracker calculate that?)

[16:05] <g7leu> fsphil: this is on a mac. not sure how to start it in HAB mode
[16:05] <fsphil_> hmm.. nor am I .. anyone else using the mac version?
[16:05] <Colin_> g7leu: from the command line - add -HAB
[16:06] <Colin_> Actually, LazyLeopard uses MACs he may know
[16:06] <g7leu> colin: things tend not to be started from the command line on a mac
[16:06] <LazyLeopard> Would expect it to hit the lower airstream and start heading south soon, of the airflow over Ipswich matches that over Cambridge...
[16:06] <fsphil_> my mac is too old for it (PPC)
[16:06] <AlanWB5RMG> dl-fldigi, check setup tab 'Misc" then sub-tab "Text capture", check box for "Enable detection & extraction"

[16:07] <Colin_> LazyLeopard: Ah, ok
[16:07] <g7leu> yes, detection and extraction is ticked
[16:07] <fsphil_> if Online is ticked, and Detect and Extract then it should upload
[16:07] <fsphil_> though you won't get the extra GUI bits
[16:08] <fsphil_> I though the Mac version installed two icons, one for HAB and one for normal mode
[16:08] <fsphil_> like it does in win and linux
[16:08] <g7leu> where is the option to tick online?

[16:09] <g7leu> ah, ok. that was freshly downloaded minutes ago
[16:09] <russss> I mean the tracker should be able to calculate speed over ground from the GPS data
[16:09] <russss> and graph it!
[16:09] <LazyLeopard> It's filtering out "+" signs, too.
[16:10] <russss> I demand more graphs.
[16:10] <fsphil_> jonsowman: bad gateway again :)
[16:10] <Randomskk> russss: work is afoot on the new version of the tracker

[16:27] <fsphil_> the little battery is working a treat so far
[16:27] <russss> oh shit there's another river.
[16:27] <kokey> if it lands there
[16:28] <LazyLeopard> G7LEU You've probably got SQU (bottom right) green. If so, turn it off.
[16:28] <LazyLeopard> SQL, even...
[16:28] <Graham_G3VZV> its getting dark outside - does it have "flasher"?
[16:28] <g7leu> lazyleopard: it was yellow. now turned off
[16:29] <LazyLeopard> That should help.
[16:29] <g7leu> but the signal is right down in the noise now and only getting the odd character. tracked it further out than i expected to though :)
[16:29] <LazyLeopard> Just hearing it now, but not decoding any more...
[16:29] <jcoxon> i'm getting it
[16:29] <adambro> is the altitude asl ?

[16:32] <eroomde> ok
[16:32] <SpeedEvil> Is M6LEP really beyond LOS?

[16:33] <Laurenceb__> fsphil: it tends to get screwed by flkdigi
[16:33] <Laurenceb__> as missing characters mess up reed solomon
[16:33] <LazyLeopard> SpeedEvil: I'm getting it just audible but not decodable...
[16:33] <fsphil_> Laurenceb__: I've added code to pad out missing characters, for the image stuff
[16:33] <adambro> should get across the river now I think

[16:34] <jcoxon> 407m
[16:35] <fsphil_> eek
[16:35] <SpeedEvil> It's coming down slowly - should easily make it
[16:35] <eroomde> it would have to make it another 2km horizontal in only 400m height
[16:35] <fsphil_> just took a quick peek at the map
[16:35] <kokey> which direction is the tide going?
[16:35] <eroomde> i guess it needs winds of >4-5mph
[16:35] <jcoxon> 51.9513,+1.1876,374
[16:35] <junderwood> It lost 250 m crossing that last bit of land. It has another 450m to go. It will make it.
[16:35] <junderwood> I bet it lands in that forest just the other side :-)
[16:36] <AlanWB5RMG> it would be cool if the groundtrack had little tick marks indicating elevation, 5k, 10k, 15k ...

[18:43] <stilldavid> using a latex balloon or a party balloon?
[18:44] <futurity> well i've got a family and work part-time, so its more cost bound rather than constrained to a particular technology

[18:45] <futurity> latex seems to give more height, but costs more in helium
[18:46] <futurity> i guess the advantage of latex is that i'm more likely to get the payload back ;)

[21:53] <Darkside> apart from that, yeah
[21:53] <Darkside> bring hot glue if you can
[21:53] <Darkside> we didnt have any at joels place, to lock the strings down

[21:54] <juxta> we'll see
[21:54] <juxta> probably end up being more like 12:00
[21:54] <juxta> but we'll try for a bit earlier
[21:54] <fsphil> I used tape to hold the strings, was a bit worried but it seemed to hold
[21:54] <Darkside> once the balloon gets inflating we can look at the payloads

[22:44] <fsphil> though an LED could be spotted further away

[22:45] <Upu> is what I have planned
[22:45] <Upu> just a quick circuit the FC can trigger below say 500 feet
[22:46] <jonsowman> we had two 1W leds that flashed every 10 seconds on our first payload

[22:57] <Upu> £25 pcm for 18 month contract
[22:57] <Upu> you can cancel these any any time
[22:57] <Upu> 1 months notice
[22:57] <Upu> which is good if you fancy loosing it :)
[22:57] <Randomskk> they look very nice
[22:58] <fsphil> there's a risk of a port scan, would cost a lot
[22:58] <Upu> http://www.nucleusnetworks.co.uk/mobile-broadband/3g-static-fixed-ip.htm
[22:58] <Upu> that was the first one but they didn't come back to me when I called them
[22:58] <fsphil> hmm

[22:59] <Upu> yeah the "back ground radiation" of the internet is about 1kb/sec
[22:59] <Upu> maybe more i've not bothered checking for a while
[22:59] <fsphil> nor here
[22:59] <Upu> actually
[23:00] <Upu> I'll ask them if they do any sort of filtering but I don't think they do as we had no issue setting up mail servers, RDP gateways and VPNs on the end of one
[23:01] <Upu> anyway I'm going to call it a night
[23:01] Nick change: Upu -> UpuZZz
[23:04] <Darkside> cool, ustream works
[23:05] <fsphil> offline?
[23:06] <Elwell> UpuZZz: sounds like the AAisp ones using 3: http://aaisp.net.uk/telecoms-mobile.html
[23:07] <Darkside> fsphil: just tested for few seconds
[23:07] <fsphil> ooh I didn't know aaisp did mobile broadband
[23:08] <Randomskk> ooh.
[23:08] <Elwell> fsphil: beware its 3g only - no fallback to 2g
[23:08] <Elwell> but if your coverage is good...
[23:08] <fsphil> good point -- it's fair in the town, but patchy else where
[23:08] <fsphil> there seemed to be good coverage at our launch site though

[23:12] <rjmunro> Has there been any writeup of today's flight yet?
[23:12] <SpeedEvil> The end is yet to be determined!
[23:12] <SpeedEvil> It's a cliffhanger at the moment
[23:13] <fsphil> stay tuned :)
[23:13] <SpeedEvil> Well - it's probably not a cliffhanger.
[23:13] <SpeedEvil> As there aren't any cliffs round there.
[23:13] <fsphil> treehanger
[23:13] <fsphil> though it was fairly flat land
[23:13] <fsphil> hedgehanger...

[23:15] <SpeedEvil> Sometimes text abbreviations really piss me off.
[23:15] <SpeedEvil> This is one of those cases.
[23:15] <fsphil> rgr
[23:18] <rjmunro> Did it have a parachute, or did it just float down?
[23:19] <SpeedEvil> It had lots of balloons
[23:19] <SpeedEvil> some of which probably stil inflated
[23:19] <rjmunro> I guessed a multi-balloon system can suffer a single balloon burst, then float down gently.
[23:19] <SpeedEvil> yep
[23:20] <Randomskk> seems likely. the balloons were all inflated to different levels, and there were two different sizes
[23:20] <fsphil> strange altitude profile though, esp. the part where it seemed to be going back up
[23:20] <Randomskk> the two small ones just made it positively buoyant - without them it sank slowly
[23:21] <rjmunro> I wonder to what degree those balloons leak at the seals rather than burst in low pressure environments.

[23:22] <fsphil> I wonder if one can be got that doesn't have any seams
[23:24] <rjmunro> Is it me, or did it descend very slowly between 16:45 and 18:30?
[23:26] <rjmunro> Sorry, just realised that's probably just missing data.
