[09:45] yeah pretty much [09:46] flight path is pretty extreme [09:46] (just to say this isn't a normal launch_ [09:46] ) [09:46] oh, make it very interesting :D [09:47] makes* [09:47] from long range forecasts it'll be off towards denmark [09:48] blimey, thats definately extreme! [09:50] just grabbing all the weather data [09:50] is the launch today ? [09:50] will run a few scenarios [09:50] earthshine, no, next saturday [09:50] ahh [09:50] there is a launch tomorrow 15:00 [09:51] hey earthshine, recieved my order yesterday, thnk you :) [09:55] hey jcoxon, what time are you launching? [10:00] it'll be ~ 14:00 UTC [10:00] saturday, right? [10:01] yeah, 13/11/10 [10:01] you too? [10:01] morning all [10:02] jcoxon: sunday here we think [10:02] is yours a floater? [10:02] okay, well if all goes well we should still be floating [10:02] though quite possibly out of range [10:02] oh very cool :) [10:02] got a prediction? [10:02] heya jonsowman [10:02] just about to gen one [10:02] its a little early to trust it [10:02] true [10:03] but its still fun :-p [10:03] hows the float predictor looking jcoxon? [10:03] hi juxta_ :) [10:03] have got it working on habhub [10:03] good stuff [10:03] without a web interface [10:03] just a single shell script really - slightly reinvented the wheel [10:04] so it's just a modified binary? [10:04] doesnt the binary support float time? [10:04] juxta_: no, rjw's one doesn't [10:05] well, it does now, since jcoxon's mods :) [10:06] jonsowman, yeah i've been relearning bash [10:06] hehe [10:06] bash is great [10:06] such as checking the time of the gfs data and only downloading if its > 6hrs [10:06] taken a bit of work [10:07] did you clone a git repo and just modify stuff? or did you fork? [10:07] just a clone [10:07] got bored of messing around [10:08] cool ok [10:08] oh righto, good work jcoxon :) [10:08] I will get round to including the float-predictor into the V2 web interface [10:09] not sure when, it might have to wait till the end of term [10:10] I intend to get through some of the github issues for the predictor as well over Xmas [10:10] especially the mobile browsers one [10:10] since JqueryMobile has been released and it's pretty cool :) [10:11] http://habhub.org/files/output1289658600.kml [10:11] if you stick that into the search box for maps.google.co.uk [10:11] nice :D [10:12] that's a pretty serious flight path! [10:13] hmm, google here says it can't find the file :( [10:13] i think it'll swing north a bit more [10:13] http://maps.google.co.uk/maps?f=q&source=s_q&hl=en&geocode=&q=http:%2F%2Fhabhub.org%2Ffiles%2Foutput1289658600.kml&sll=53.800651,-4.064941&sspn=21.718578,67.631836&ie=UTF8&ll=52.689702,4.372559&spn=5.70193,16.907959&z=7 [10:13] juxta_: ^^ [10:14] MoALTz (~no@92.21.150.137) left irc: Ping timeout: 265 seconds [10:14] hmm, same issue jonsowman :( [10:15] how weird [10:15] indeed [10:15] http://lister.hexoc.com/alpha/float1.png [10:15] http://habhub.org/files/ [10:15] well here's a screenshot [10:18] oh wow [10:18] jonsowman, you up for being balloon filler master?

[10:19] jcoxon: hehe I think it's going to be a two or three person job [10:19] especially if it's windy [10:20] jonsowman, in some ways its the most important part [10:20] :-p [10:20] juxta_, i don't unfortunately [10:20] better let you do it then :D [10:20] nah [10:20] i've got a payload to make sure it working [10:20] you know last minute debugging [10:20] Adam and I will definitely be around, possibly a couple of other CUSF people too [10:20] okay cool [10:20] I'm sure we will manage [10:20] steve will be there as well [10:20] oh excellent [10:21] more pairs of hands are definitely better [10:21] we'll just take our time [10:21] find a non-windy spot [10:21] no worries jcoxon - met the australian importer for trimble today and he mentioned some free modules - wanted to see if you could make use of any :) [10:21] juxta_, we could make more... [10:21] but to tell the truth i prefer ublox [10:22] yeah me too [10:22] but I wont turn them down for free - will let you know how it pans out :) [10:22] I could do with a couple... how much are you after for them? [10:24] juxta_: you got a prediction for sunday yet? [10:24] [10:24] hey plantain [10:24] yeah [10:24] looking pretty good [10:25] link? [10:25] near murray bridge [10:25] sec [10:25] this is darkside btw [10:25] i am at plantains house [10:25] jonsowman, does cherokee heavily cache? [10:26] cherokee the webserver? yes, very heavily [10:26] jcoxon: yes [10:26] is it causing you issues? [10:26] its IO cache is one of its best and worst features [10:26] not too much [10:27] its just that if i gen a new kml it doesn't change :-p [10:27] oh ok [10:27] give me two seconds [10:27] I'll tell it to not cache KMLs [10:28] morning! [10:28] yo fsphil [10:28] juxta_: ? [10:31] jcoxon: try that [10:31] it should exclude KMLs from the IO cache now [10:32] hey plantain, sorry: http://habhub.org/predict/#!/uuid=b92c67ce9c4c70134ac5f4e74f97d83c79eb8741 [10:34] heya jonsowman, we'll be trying the offline predictor this weekend in the chase cars :) [10:34] oo excellent [10:34] let me know how it goes [10:34] shall do [10:34] this is the one you compiled in cygwin for windows right? [10:34] yep [10:34] jonsowman, oh dear, oops [10:34] mm delicious efficiency [10:34] jcoxon: uh oh... what have I done? [10:34] juxta_: haha :D [10:35] no its more what haven't i done... [10:35] that flight path is without float... [10:35] :o [10:35] oh... [10:36] jonsowman: ever have any issues with the predictor binary locking up? [10:37] I uh, never bothered to add a timeout on the process, i probably should do that [10:37] juxta_: no I haven't [10:37] it seems to just quit without warning when it comes across something it doesn't like [10:37] ok, well that's good news [10:37] it's never frozen on me [10:37] that's fine, i can handle that :) [10:38] plantain: got a few more of those mini video cameras donated today [10:38] shipit (~sumeet@c-67-180-23-104.hsd1.ca.comcast.net) left irc: Remote host closed the connection [10:41] hey jonsowman - what times do you figure the models become available on nomads? [10:41] 01:00z, 07:00z.. etc? [10:42] the dataset for a given time comes out about 5 hours after [10:42] oh, righto [10:42] so the 00z model is released about 04-05z [10:42] 95% of the time anyway [10:42] sometimes they're released 6-7hours after [10:42] and sometimes never at all [10:43] I'll just do 0z, 6z, 12z and 18z then [10:43] for grabbing data? [10:43] i only had it going every 12 hours before but when you're looking a week ahead the new models make a big difference [10:43] yeah, for the hourly jobs [10:44] I tuned this quite carefully for the hourly predictor at CUSF [10:44] give me a second [10:44] I'll find the crontab [10:44] oh, brilliant :D [10:45] jonsowman, hopefully the weather will improve before sat... [10:46] will keep an eye [10:47] juxta_: I went for 05, 11, 17 and 23z [10:47] ok great, thanks jonsowman [10:47] though I have a commented line with 00/06/12/18 saying "use this if it's skipping datasets" [10:47] haha [10:47] okie doke [10:48] jcoxon: yes, hopefully it'll improve [10:48] did you use HD? [10:48] juxta_: I think it still does, yes [10:48] it's pointless though [10:48] yeah, it doesnt really seem to be worth it [10:48] jcoxon: as usual we'll need to decide before 12pm on Friday [10:48] for NOTAM purposes [10:48] just takes much longer to grab [10:49] juxta_: indeed, I personally wouldn't bother if I were you [10:49] jonsowman: is the change just in the url generation? [10:49] jonsowman, we'll know by thurs i reckon [10:50] juxta_: https://github.com/jonsowman/cusf-standalone-predictor/blob/master/predict.py [10:50] see line 478-481 [10:50] jcoxon: okay, no problem [10:50] will notify Chu of a potential launch [10:51] ok cool, so that's all it is - the data format itself is unchanged? [10:52] correct [10:53] well the format changes slightly but the way the predictor is written, it automatically copes [10:53] excellent :) [10:53] will switch to the regular GFS data in that case then [10:53] good plan [10:54] uuuurgh [10:54] im tired [10:54] HD vs regular GFS - is the difference just the resolution so to speak? [10:54] juxta_: if it lands *in* the murray [10:54] oh man [10:55] ie more cells for a given area [10:55] yes, that would be rather annoying [10:55] but also unlikely :) [10:55] haha [10:55] also how am i going to communicate between chase cars >_> [10:55] how many people will be in the lonely planet car? [10:55] oh I'm sure we'll work something out ;) [10:55] juxta_: there are many, many differences, but the main one that matters to us is the "vertical resolution" [10:56] GFS like 26 levels up through the atmosphere [10:56] Darkside, I think Tony, Chris + his girlfriend [10:56] each containing the wind speed and direction for that level [10:56] whereas HD has 47 [10:56] ah right - got it :) [10:56] juxta_: who? [10:56] potentially twice as much data then I guess [10:56] juxta_: the "Information" bit in the readme here has some links if you want to know more [10:56] https://github.com/jonsowman/cusf-standalone-predictor [10:57] Darkside: lonely planet people [10:57] the car is a prius, so it will be even less off road capable than mine ;p [10:57] >_> [10:57] oh yay [10:57] also i hope i have 3G reception the whole way.. [10:58] oh right, thanks jonsowman - I'd read that but never noticed the links [10:58] will have a read [10:58] :) [10:58] juxta_: soooooo, communication between cars? [10:58] i'm sure it'll be fine Darkside, it's probably along freeway the whole way [10:58] how will i talk to you about whats going on >_> [10:59] uhf cb or maybe another band, I'll be there in spirit as a second operator to oversee you :) [10:59] hehe check out this: [11:00] http://maps.google.com/?q=http://www.robertharrison.org/listen/receivers.php&t=p [11:00] all the people who have run dl-fldigi and put in their coords [11:00] gnome terminal link fail -.- [11:00] pff [11:00] Jasperw (~jasperw@2001:470:92f1:0:223:5aff:fef5:cce) joined #highaltitude. [11:00] jcoxon: that's pretty cool [11:01] Darkside, actually I think UHF CB is about the best we can do, even if we used another band power would be the issue as you'll be handheld I guess... we'll probably stay very close though i think [11:02] ok [11:02] jonsowman, what time is xaben launch tomorrow? [11:02] i'll probably get the lonely planet guys to tail you anyway [11:02] about 1500GMT [11:02] of course we shoull have mobile coverage [11:02] why so late? [11:02] should* [11:02] it'll be nearly dark [11:02] it might be slightly earlier [11:02] or is that the point? [11:02] Randomskk and I are busy all morning [11:02] also i've got two others that were interested in coming along for the chase, and they have a car [11:03] a freaking subaru WRX... [11:03] but its a car [11:03] it might be nearer 2pm [11:03] Steve is going to turn up and get ready, and Randomskk and I will just turn up, notify the tower, watch the launch, then disappear [11:03] and they'd probably just tail whatever car i'm in >_> [11:03] do we know them? [11:03] jonsowman, i'll setup my home radio [11:03] for people to play with [11:04] though it'll probably be out of range [11:04] jcoxon: that'd be cool [11:04] we will track from college once we're home [11:04] we may need to be a bit careful about the amount of people coming, so far we have lots and lots of people who've said they'll come Darkside [11:04] though we only have a whip currently [11:04] Action: fsphil will try tracking although didn't have much luck with the last floater [11:04] we might move the launch site to the local oval if the weather permits [11:04] ahhh [11:04] i'll let them know [11:04] jcoxon: we'll try and get the trackatron with the yagi up at CUED for your launch [11:05] yeah that would be great [11:05] right will bbl [11:05] jcoxon (~jcoxon@nat76.mia.three.co.uk) left irc: Quit: Leaving [11:05] I so wanna build one of those [11:05] fsphil: do it :D [11:05] ours is completely magic now [11:06] automatically downloads balloon positions from the listener and points the yagi at the balloon [11:06] we just sit there and smile [11:06] :D [11:06] I've loads of motors and bits, though I suspect I'd need a stepper motor [11:06] jonsowman: i was going to do that :P [11:06] dammit [11:06] i have a 24dBi dish for 900MHZ i can borrow from uni :P [11:06] 24! [11:06] wow [11:06] they used to use it for radar experiments, now they dont use it anymore [11:07] wel, i dunno if its 24dB for 900MHZ [11:07] its the same size as a 2.4GHZ 24dBi dish [11:07] fsphil: you could get away with a normal geared down motor and an encoder/other feedback system [11:07] but has a 900MHZ dipole on it [11:07] might be more effort than it's worth though [11:07] yea agreed [11:07] and is mounted on 2 stepper motors, [11:07] nice [11:07] Darkside: remove the dish and stick a yagi on there [11:07] hehe [11:07] jonsowman, would it be quick enough to track the iss? [11:08] probably [11:08] it can shift pretty fast when it wants [11:08] sweet [11:08] I don't know if it's ever been tried [11:08] we didn't build the rotator unit though [11:08] it's an off-the-shelf uni [11:08] *unit [11:09] direct drive or geared? [11:10] I think geared, but I'm not sure - eroomde will know [11:13] would be tricky enough to build [11:13] should takea pic of the one at uni [11:14] its direct driven too [11:14] I'm not sure how I could make the alt move without a gear [11:22] GW8RAK (~chatzilla@client-86-23-103-27.brhm.adsl.virginmedia.com) joined #highaltitude.

[18:56] the most important thing for hab'ing is line-of-sight [18:56] There's an American who uses a surplus 4" gun mounting as a rotator for his dish! [18:56] :o now thats extremely worrying, where did the gun go?! lol [18:57] You'll probably find 10dB gain is enough for most HAB'ing. And a wide bandwidth so steering doesn't have to be too precise. [18:57] it's america [18:57] From the picturs I've seen, it looks like he has just shoved the dish support down the barrel. [18:57] eroomde: That looks like it comes from the age of sail. [18:58] lol [18:58] or one of those world war two radars [18:58] EME has got considerably easier over the years with low noise preamps and digital signal processing.

[19:11] If you can face the transnational trek to cambridge, you'd be more than welcome to launch at our site [19:12] its certainly possible, definately have to be a weekend though, probably a saturday. [19:13] suits us [19:13] lectures during the week [19:14] awsome :D .. not sure what kind of eta im looking at, but most of the hardware should have arrived by the end of next week, and my c programmer is confident the coding is fairl straightforward, he spent 2 hours fiddling with the mega last night [19:15] have you come across our hourly predictor? cuspaceflight.co.uk/hourly-predictions [19:16] oh no, thats new to me, let me take a look... [19:16] That will provide hours of fun. [19:16] you set it up with a flight profile (it's currently set up with a fairly typical one) and it shows you the locus of landing spots if you were to launch each hour, on the hour, for the next five days [19:16] it's basically a 'week at a glance' for seeing if there's a flight window [19:17] so when you're think you're ready to make a go of it you can start watching that to see if it looks like there's a launch opportunity on the horizon [19:17] thats an amazing piece of coding right there!

[21:46] don't think so [21:47] I've no idea [21:47] I'm hoping Steve appears on here some point tonight [21:53] he's at ears [21:53] well actually i guess that will have finished now [21:54] DarkCow (~DarkCow@5ad9ea12.bb.sky.com) left irc: Read error: Connection timed out [21:54] hmm... rtty over led only works at 50 baud [21:55] DarkCow (~DarkCow@5ad9ea12.bb.sky.com) joined #highaltitude.

[22:57] yeah [22:57] Hmm [22:57] perhaps send Steve and email and notify him [22:57] he'll probably fly XABEN if he can retrieve [22:57] it is tight though [22:57] which will be more interesting to track [22:58] hmmm to tight really [22:58] shame my beacon is down here [22:58] could easily add gps to it in about 3 minutes [22:58] we have ferret but jon doesn't want it to get a bit wet [22:59] oh we could.. but it's a bit of a waste [22:59] it is [22:59] a little pointless [22:59] a lot of work went into the case especially [22:59] probably woudln't fly that case, certainly [22:59] nah stick to the beacon [22:59] but it would be sad to send ferret to a watery grave [22:59] it would [22:59] drowning ferrets is generally frowned upon [22:59] indeed [22:59] right night all [23:00] night jcoxon [23:00] seeya [23:00] will follow on twitter tomorrow [23:00] have to work [23:00] will keep twitter and #highaltitude updated [23:00] though twitter is easier from phones [23:00] jcoxon (~jcoxon@cpc1-lanc4-0-0-cust720.3-3.cable.virginmedia.com) left irc: Quit: Leaving [23:01] Upu (~Upu@ubn.upuaut.net) left irc: [23:11] mmm i'd rather you didn't fly that payload case into the sea [23:11] took me ages [23:11] hehe [23:11] sadly longer than it took you guys to build a working flight computer [23:11] guess i'm not the fastest [23:12] but it's a very nice case [23:12] whereas ferret is super-hacky [23:12] discussing launch next saturday? [23:15] we were discussing adding a gps tracking system to the launch tomorrow [23:15] but since it's probably going in the sea, probably better not [23:15] dam jcoxon left :( [23:16] oh 2morrow [23:16] cancelled then? [23:16] it'll just a CW beacon [23:16] no GPS [23:16] s/just/just be/ [23:16] next weekedn is still on awaiting a better forecast at least? [23:16] oh ok [23:17] hmm what time launch? [23:17] hopefully next weekend will be OK for james' launch [23:17] tomorrow, about 1400-1500GMT (see topic) [23:17] on saturday, probably about the same time [23:17] I'm not sure on that though, best ask james [23:17] i could probably receive at work.... dont have a yagi tho [23:18] it's not going to be very interesting telemetry [23:18] we can try and DF it though [23:18] ntx2 i presume?

I've never tweeted! [23:24] jonsowman and dan bowen today. how do they find it? [23:24] this is all baffling [23:24] twitter suggested you [23:24] i was logged into the cuspaceflight account at the time [23:25] it's all twitter's fault. [23:27] ah right [23:27] how confusing [23:28] well, maybe i could pretend to be a buddhist monk [23:28] people subscribe to my silent tweets [23:28] an excellent idea [23:28] http://www.i1wqrlinkradio.com/antype/ch29/chiave1622.htm [23:28] nearly 12dBi ?! [23:28] am i reading that right? [23:29] impressive [23:29] that's a lot of gain for a coat hangar [23:29] thats what ive got [23:29] well, copper wire [23:29] and sandwiched into some plastic board [23:30] more like -110dBm then, should see something on the cc1020 sdr [23:30] yeah but look at the elevation profile!! [23:30] heh [23:31] wouldn't make the best hab antenna is if was statically mounted [23:31] true [23:32] right, I'm off. night all [23:32] see you [23:34] Nick change: SpeedEvil1 -> SpeedEvil [23:36] juxta (Bogaurd@ppp203-122-193-94.static.internode.on.net) joined #highaltitude.
