[09:38] <earthshine> morning
[09:38] <jcoxon> hey earthshine
[09:38] <jcoxon> i'm really sorry i haven't sent that board yet
[09:38] <earthshine> ahh I was going to ask about that
[09:38] <jcoxon> have been on call all week so haven't actually seen daylight nor a post office
[09:38] <earthshine> i thought it had been lost by Royal Fail
[09:38] <earthshine> no worries - i'm not desperate for it
[09:43] <jcoxon> ooo my flickr account has had 99,147 views
[09:43] <NigeySWales> morning all
[09:43] <jcoxon> nearly there...
[09:44] <NigeySWales> jcoxon, i can sit and press refresh 853 times for 50p a click? :P lol
[09:45] <jcoxon> ummm i could do it myself for a lower rate :-)
[09:45] <NigeySWales> hah true..:p
[09:45] <NigeySWales> everything looking good for your launch ?
[09:45] <jcoxon> yeah pretty much
[09:46] <jcoxon> flight path is pretty extreme
[09:46] <jcoxon> (just to say this isn't a normal launch_
[09:46] <jcoxon> )
[09:46] <NigeySWales> oh, make it very interesting :D
[09:47] <NigeySWales> makes*
[09:47] <jcoxon> from long range forecasts it'll be off towards denmark
[09:48] <NigeySWales> blimey, thats definately extreme!
[09:50] <jcoxon> just grabbing all the weather data
[09:50] <earthshine> is the launch today ?
[09:50] <jcoxon> will run a few scenarios
[09:50] <jcoxon> earthshine, no, next saturday
[09:50] <earthshine> ahh
[09:50] <jcoxon> there is a launch tomorrow 15:00
[09:51] <NigeySWales> hey earthshine, recieved my order yesterday, thnk you :)
[09:55] <juxta_> hey jcoxon, what time are you launching?
[10:00] <jcoxon> it'll be ~ 14:00 UTC
[10:00] <juxta_> saturday, right?
[10:01] <jcoxon> yeah, 13/11/10
[10:01] <jcoxon> you too?
[10:01] <jonsowman> morning all
[10:02] <juxta_> jcoxon: sunday here we think
[10:02] <juxta_> is yours a floater?
[10:02] <jcoxon> okay, well if all goes well we should still be floating
[10:02] <jcoxon> though quite possibly out of range
[10:02] <juxta_> oh very cool :)
[10:02] <juxta_> got a prediction?
[10:02] <juxta_> heya jonsowman
[10:02] <jcoxon> just about to gen one
[10:02] <jcoxon> its a little early to trust it
[10:02] <juxta_> true
[10:03] <jcoxon> but its still fun :-p
[10:03] <jonsowman> hows the float predictor looking jcoxon?
[10:03] <jonsowman> hi juxta_ :)
[10:03] <jcoxon> have got it working on habhub
[10:03] <jonsowman> good stuff
[10:03] <jcoxon> without a web interface
[10:03] <jcoxon> just a single shell script really - slightly reinvented the wheel
[10:04] <jonsowman> so it's just a modified binary?
[10:04] <juxta_> doesnt the binary support float time?
[10:04] <jonsowman> juxta_: no, rjw's one doesn't
[10:05] <jonsowman> well, it does now, since jcoxon's mods :)
[10:06] <jcoxon> jonsowman, yeah i've been relearning bash
[10:06] <jonsowman> hehe
[10:06] <jonsowman> bash is great
[10:06] <jcoxon> such as checking the time of the gfs data and only downloading if its > 6hrs
[10:06] <jcoxon> taken a bit of work
[10:07] <jonsowman> did you clone a git repo and just modify stuff? or did you fork?
[10:07] <jcoxon> just a clone
[10:07] <jcoxon> got bored of messing around
[10:08] <jonsowman> cool ok
[10:08] <juxta_> oh righto, good work jcoxon :)
[10:08] <jonsowman> I will get round to including the float-predictor into the V2 web interface
[10:09] <jonsowman> not sure when, it might have to wait till the end of term
[10:10] <jonsowman> I intend to get through some of the github issues for the predictor as well over Xmas
[10:10] <jonsowman> especially the mobile browsers one
[10:10] <jonsowman> since JqueryMobile has been released and it's pretty cool :)
[10:11] <jcoxon> http://habhub.org/files/output1289658600.kml
[10:11] <jcoxon> if you stick that into the search box for maps.google.co.uk
[10:11] <jonsowman> nice :D
[10:12] <jonsowman> that's a pretty serious flight path!
[10:13] <juxta_> hmm, google here says it can't find the file :(
[10:13] <jcoxon> i think it'll swing north a bit more
[10:13] <jonsowman> 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

[10:15] <jcoxon> http://habhub.org/files/
[10:15] <jonsowman> well here's a screenshot
[10:18] <juxta_> oh wow
[10:18] <jcoxon> jonsowman, you up for being balloon filler master?
[10:18] <juxta_> that looks like a good flight path
[10:19] <juxta_> jcoxon, do you still have any lassen breakouts?
[10:19] GeekShadow (~Antoine@reactos/tester/GeekShadow) joined #highaltitude.
[10:19] <jonsowman> jcoxon: hehe I think it's going to be a two or three person job
[10:19] <jonsowman> especially if it's windy
[10:20] <jcoxon> jonsowman, in some ways its the most important part
[10:20] <jcoxon> :-p
[10:20] <jcoxon> juxta_, i don't unfortunately
[10:20] <jonsowman> better let you do it then :D
[10:20] <jcoxon> nah
[10:20] <jcoxon> i've got a payload to make sure it working
[10:20] <jcoxon> you know last minute debugging
[10:20] <jonsowman> Adam and I will definitely be around, possibly a couple of other CUSF people too
[10:20] <jonsowman> okay cool
[10:20] <jonsowman> I'm sure we will manage
[10:20] <jcoxon> steve will be there as well
[10:20] <jonsowman> oh excellent
[10:21] <jonsowman> more pairs of hands are definitely better
[10:21] <jcoxon> we'll just take our time
[10:21] <jcoxon> find a non-windy spot
[10:21] <juxta_> 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] <jcoxon> juxta_, we could make more...
[10:21] <jcoxon> but to tell the truth i prefer ublox
[10:22] <juxta_> yeah me too
[10:22] <juxta_> but I wont turn them down for free - will let you know how it pans out :)
[10:22] <jonsowman> I could do with a couple... how much are you after for them?
[10:24] <plantain> juxta_: you got a prediction for sunday yet?
[10:24] <plantain> <Darkside>
[10:24] <juxta_> hey plantain
[10:24] <juxta_> yeah
[10:24] <juxta_> looking pretty good
[10:25] <plantain> link?
[10:25] <juxta_> near murray bridge
[10:25] <juxta_> sec
[10:25] <plantain> <Darkside> this is darkside btw
[10:25] <plantain> <Darkside> i am at plantains house
[10:25] <jcoxon> jonsowman, does cherokee heavily cache?
[10:26] <plantain> cherokee the webserver? yes, very heavily
[10:26] <jonsowman> jcoxon: yes
[10:26] <jonsowman> is it causing you issues?
[10:26] <jonsowman> its IO cache is one of its best and worst features
[10:26] <jcoxon> not too much
[10:27] <jcoxon> its just that if i gen a new kml it doesn't change :-p
[10:27] <jonsowman> oh ok
[10:27] <jonsowman> give me two seconds
[10:27] <jonsowman> I'll tell it to not cache KMLs
[10:28] <fsphil> morning!
[10:28] <jonsowman> yo fsphil
[10:28] <plantain> juxta_: ?
[10:31] <jonsowman> jcoxon: try that
[10:31] <jonsowman> it should exclude KMLs from the IO cache now
[10:32] <juxta_> hey plantain, sorry: http://habhub.org/predict/#!/uuid=b92c67ce9c4c70134ac5f4e74f97d83c79eb8741
[10:34] <juxta_> heya jonsowman, we'll be trying the offline predictor this weekend in the chase cars :)
[10:34] <jonsowman> oo excellent
[10:34] <jonsowman> let me know how it goes
[10:34] <juxta_> shall do
[10:34] <jonsowman> this is the one you compiled in cygwin for windows right?
[10:34] <juxta_> yep
[10:34] <jcoxon> jonsowman, oh dear, oops
[10:34] <juxta_> mm delicious efficiency
[10:34] <jonsowman> jcoxon: uh oh... what have I done?
[10:34] <jonsowman> juxta_: haha :D
[10:35] <jcoxon> no its more what haven't i done...
[10:35] <jcoxon> that flight path is without float...
[10:35] <jonsowman> :o
[10:35] <jonsowman> oh...
[10:36] <juxta_> jonsowman: ever have any issues with the predictor binary locking up?
[10:37] <juxta_> I uh, never bothered to add a timeout on the process, i probably should do that
[10:37] <jonsowman> juxta_: no I haven't
[10:37] <jonsowman> it seems to just quit without warning when it comes across something it doesn't like
[10:37] <juxta_> ok, well that's good news
[10:37] <jonsowman> it's never frozen on me
[10:37] <juxta_> that's fine, i can handle that :)
[10:38] <juxta_> 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] <juxta_> hey jonsowman - what times do you figure the models become available on nomads?
[10:41] <juxta_> 01:00z, 07:00z.. etc?
[10:42] <jonsowman> the dataset for a given time comes out about 5 hours after
[10:42] <juxta_> oh, righto
[10:42] <jonsowman> so the 00z model is released about 04-05z
[10:42] <jonsowman> 95% of the time anyway
[10:42] <jonsowman> sometimes they're released 6-7hours after
[10:42] <jonsowman> and sometimes never at all
[10:43] <juxta_> I'll just do 0z, 6z, 12z and 18z then
[10:43] <jonsowman> for grabbing data?
[10:43] <juxta_> 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] <juxta_> yeah, for the hourly jobs
[10:44] <jonsowman> I tuned this quite carefully for the hourly predictor at CUSF
[10:44] <jonsowman> give me a second
[10:44] <jonsowman> I'll find the crontab
[10:44] <juxta_> oh, brilliant :D
[10:45] <jcoxon> jonsowman, hopefully the weather will improve before sat...
[10:46] <jcoxon> will keep an eye
[10:47] <jonsowman> juxta_: I went for 05, 11, 17 and 23z
[10:47] <juxta_> ok great, thanks jonsowman
[10:47] <jonsowman> though I have a commented line with 00/06/12/18 saying "use this if it's skipping datasets"
[10:47] <juxta_> haha
[10:47] <juxta_> okie doke
[10:48] <jonsowman> jcoxon: yes, hopefully it'll improve
[10:48] <juxta_> did you use HD?
[10:48] <jonsowman> juxta_: I think it still does, yes
[10:48] <jonsowman> it's pointless though
[10:48] <juxta_> yeah, it doesnt really seem to be worth it
[10:48] <jonsowman> jcoxon: as usual we'll need to decide before 12pm on Friday
[10:48] <jonsowman> for NOTAM purposes
[10:48] <juxta_> just takes much longer to grab
[10:49] <jonsowman> juxta_: indeed, I personally wouldn't bother if I were you
[10:49] <juxta_> jonsowman: is the change just in the url generation?
[10:49] <jcoxon> jonsowman, we'll know by thurs i reckon
[10:50] <jonsowman> juxta_: https://github.com/jonsowman/cusf-standalone-predictor/blob/master/predict.py
[10:50] <jonsowman> see line 478-481
[10:50] <jonsowman> jcoxon: okay, no problem
[10:50] <jonsowman> will notify Chu of a potential launch
[10:51] <juxta_> ok cool, so that's all it is - the data format itself is unchanged?
[10:52] <jonsowman> correct
[10:53] <jonsowman> well the format changes slightly but the way the predictor is written, it automatically copes
[10:53] <juxta_> excellent :)
[10:53] <juxta_> will switch to the regular GFS data in that case then
[10:53] <jonsowman> good plan
[10:54] <Darkside> uuuurgh
[10:54] <Darkside> im tired
[10:54] <juxta_> HD vs regular GFS - is the difference just the resolution so to speak?
[10:54] <Darkside> juxta_: if it lands *in* the murray
[10:54] <Darkside> oh man
[10:55] <juxta_> ie more cells for a given area
[10:55] <juxta_> yes, that would be rather annoying
[10:55] <juxta_> but also unlikely :)
[10:55] <Darkside> haha
[10:55] <Darkside> also how am i going to communicate between chase cars >_>
[10:55] <Darkside> how many people will be in the lonely planet car?
[10:55] <juxta_> oh I'm sure we'll work something out ;)
[10:55] <jonsowman> juxta_: there are many, many differences, but the main one that matters to us is the "vertical resolution"
[10:56] <jonsowman> GFS like 26 levels up through the atmosphere
[10:56] <juxta_> Darkside, I think Tony, Chris + his girlfriend
[10:56] <jonsowman> each containing the wind speed and direction for that level
[10:56] <jonsowman> whereas HD has 47
[10:56] <juxta_> ah right - got it :)
[10:56] <Darkside> juxta_: who?
[10:56] <juxta_> potentially twice as much data then I guess
[10:56] <jonsowman> juxta_: the "Information" bit in the readme here has some links if you want to know more
[10:56] <jonsowman> https://github.com/jonsowman/cusf-standalone-predictor
[10:57] <juxta_> Darkside: lonely planet people
[10:57] <juxta_> the car is a prius, so it will be even less off road capable than mine ;p
[10:57] <Darkside> >_>
[10:57] <Darkside> oh yay
[10:57] <Darkside> also i hope i have 3G reception the whole way..
[10:58] <juxta_> oh right, thanks jonsowman - I'd read that but never noticed the links
[10:58] <juxta_> will have a read
[10:58] <jonsowman> :)
[10:58] <Darkside> juxta_: soooooo, communication between cars?
[10:58] <juxta_> i'm sure it'll be fine Darkside, it's probably along freeway the whole way
[10:58] <Darkside> how will i talk to you about whats going on >_>
[10:59] <juxta_> uhf cb or maybe another band, I'll be there in spirit as a second operator to oversee you :)
[10:59] <jcoxon> hehe check out this:

[11:00] <jonsowman> jcoxon: that's pretty cool
[11:01] <juxta_> 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] <Darkside> ok
[11:02] <jcoxon> jonsowman, what time is xaben launch tomorrow?
[11:02] <Darkside> i'll probably get the lonely planet guys to tail you anyway
[11:02] <jonsowman> about 1500GMT
[11:02] <juxta_> of course we shoull have mobile coverage
[11:02] <jcoxon> why so late?
[11:02] <juxta_> should*
[11:02] <jcoxon> it'll be nearly dark
[11:02] <jonsowman> it might be slightly earlier
[11:02] <jcoxon> or is that the point?
[11:02] <jonsowman> Randomskk and I are busy all morning
[11:02] <Darkside> also i've got two others that were interested in coming along for the chase, and they have a car
[11:03] <Darkside> a freaking subaru WRX...
[11:03] <Darkside> but its a car
[11:03] <jonsowman> it might be nearer 2pm
[11:03] <jonsowman> 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] <Darkside> and they'd probably just tail whatever car i'm in >_>
[11:03] <juxta_> do we know them?
[11:03] <jcoxon> jonsowman, i'll setup my home radio
[11:03] <jcoxon> for people to play with
[11:04] <jcoxon> though it'll probably be out of range
[11:04] <jonsowman> jcoxon: that'd be cool
[11:04] <jonsowman> we will track from college once we're home
[11:04] <juxta_> 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] <jonsowman> 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] <juxta_> we might move the launch site to the local oval if the weather permits
[11:04] <Darkside> ahhh
[11:04] <Darkside> i'll let them know
[11:04] <jonsowman> jcoxon: we'll try and get the trackatron with the yagi up at CUED for your launch
[11:05] <jcoxon> yeah that would be great
[11:05] <jcoxon> right will bbl

[11:06] <jonsowman> automatically downloads balloon positions from the listener and points the yagi at the balloon
[11:06] <jonsowman> we just sit there and smile
[11:06] <jonsowman> :D
[11:06] <fsphil> I've loads of motors and bits, though I suspect I'd need a stepper motor
[11:06] <Darkside> jonsowman: i was going to do that :P
[11:06] <Darkside> dammit
[11:06] <Darkside> i have a 24dBi dish for 900MHZ i can borrow from uni :P
[11:06] <jonsowman> 24!
[11:06] <jonsowman> wow
[11:06] <Darkside> they used to use it for radar experiments, now they dont use it anymore
[11:07] <Darkside> wel, i dunno if its 24dB for 900MHZ
[11:07] <Darkside> its the same size as a 2.4GHZ 24dBi dish
[11:07] <jonsowman> fsphil: you could get away with a normal geared down motor and an encoder/other feedback system
[11:07] <Darkside> but has a 900MHZ dipole on it
[11:07] <jonsowman> might be more effort than it's worth though
[11:07] <fsphil> yea agreed
[11:07] <Darkside> and is mounted on 2 stepper motors,
[11:07] <jonsowman> nice
[11:07] <jonsowman> Darkside: remove the dish and stick a yagi on there
[11:07] <jonsowman> hehe
[11:07] <fsphil> jonsowman, would it be quick enough to track the iss?
[11:08] <jonsowman> probably
[11:08] <jonsowman> it can shift pretty fast when it wants
[11:08] <fsphil> sweet
[11:08] <jonsowman> I don't know if it's ever been tried
[11:08] <jonsowman> we didn't build the rotator unit though
[11:08] <jonsowman> it's an off-the-shelf uni
[11:08] <jonsowman> *unit
[11:09] <fsphil> direct drive or geared?
[11:10] <jonsowman> I think geared, but I'm not sure - eroomde will know
[11:13] <fsphil> would be tricky enough to build
[11:13] <Darkside> should takea pic of the one at uni
[11:14] <Darkside> its direct driven too
[11:14] <fsphil> I'm not sure how I could make the alt move without a gear

[12:52] <NigeySWales> meh cant find any 220ohm resistors :/
[12:52] <juxta_> what do you need them for NigeySWales?
[12:53] <juxta_> you can probably just use something else that's in the right sort of ballpark
[12:53] <NigeySWales> im going through 1 of the arduino tutorials, the 12 led fade in / out
[12:53] <juxta_> I don't know it - is there a link to a schematic?
[12:54] <NigeySWales> yup 2 secs ill find it
[12:55] <NigeySWales> http://arduino.cc/en/Tutorial/AnalogWriteMega
[12:57] <juxta_> okay, you can substitute something else instead
[12:58] <juxta_> do you have anything sort of close on hand?
[12:58] <juxta_> (say maybe 330, 390, 470 ohm)
[12:59] <NigeySWales> let me check, i had a pack given to me yesterday but ive no idea on values, didnt check 2 secs....most of them are blue if that helps..lol
[12:59] <juxta_> heh - the bands on them is what you're interested in
[13:00] <NigeySWales> oki, i got a colour code sheet, let me see if my maths is ok lol
[13:00] <juxta_> you can always use a multimeter to check them too
[13:01] <NigeySWales> oh.. now that i can do, brb! thisll be fun theres only 10 packs..lol

[16:46] <futurity> Hi, does anyone know if the launch is still on for tomorrow?
[16:47] <DanielRichman> futurity: jonsowman might know for sure. I think it is though.
[16:47] <futurity> Cool
[16:47] <futurity> i should be able to listen in tomorrow afternoon
[16:47] <jonsowman> futurity: yes it's happening unless Something Bad happens
[16:48] <jonsowman> launch will be between 2-3pm
[16:48] <futurity> jonsowman: thanks for letting me know, i may need some help if the software needs updating to decode the signals?
[16:49] <jonsowman> the original plan was the launch the XABEN payload in dl-fldigi
[16:49] <jonsowman> I'm not sure if that's still the case
[16:49] <NigeySWales> jonsowman, how far away can someone be with a reciever to track the flight ?
[16:49] <jonsowman> if RocketBoy appears on here, ask him
[16:49] <jonsowman> NigeySWales: depends on many things
[16:49] <jonsowman> if you're high up and have a Yagi and a good radio, you may well hear it from where you are
[16:49] <jonsowman> I can't really say for sure
[16:50] <NigeySWales> okies, i'd fail on the altitude bit, i think where i am is only about 80m above sea level :(
[16:50] <fsphil> a clear view of the south-east horizon and you should be fine to track

[17:53] <DanielRichman> by default it sits spouting telemetry on various modes and occasionally listening for an uplink; there are two functions through which alterations to the rotation can be inserted; radio_stream_queue queues up some sort of data to be sent with whatever mode was in use at the time (e.g., ssdv), and radio_mode_queue queues up an unusual mode to be used (e.g., sstv)

[18:49] <jonsowman> well, 21el is huge
[18:49] <jonsowman> do you need such a massive one?
[18:49] <NigeySWales> looks it too lol.. i think maybe not, smaller will be fine!
[18:50] <jonsowman> try a 9-11el one
[18:50] <NigeySWales> 9-11 oki will look some up tnx jon
[18:50] <GW8RAK_> Crossed yagis are quite useful if you ever want to pick up satellite transmissions.
[18:51] <fsphil> This one is also good: http://www.radioworld.co.uk/catalog/a430s10r-diamond-430440mhz-70cm-yagi-p-3962.html
[18:51] <jonsowman> NigeySWales: that one that fsphil mentions is excellent
[18:51] <GW8RAK_> I've got one of the 21 ele yagis, but it is big.
[18:51] <jonsowman> I recommend that too
[18:51] <NigeySWales> ah thanks jon, within budget to :D
[18:52] <NigeySWales> GW8RAK, its looks gigantic !!
[18:52] <GW8RAK_> I think it's about 5m long
[18:52] <GW8RAK_> And there's a lot of windage on a rotator
[18:53] <NigeySWales> :o
[18:53] <GW8RAK_> http://www.moonraker.eu/Amateur-Radio/Beam-Antennas/Crossed-Yagi
[18:53] <eroomde> NigeySWales: if you want to let your inner antenna nerd run free, you can phase smaller yagis together side by side to make the effect of a single larger one
[18:54] <NigeySWales> oh now that sounds like a fun idea!!
[18:54] <eroomde> some people take this idea to heart and create vast antenna arrays to do 'EME' - earth-moon-earth - where they blast high power at the moon and listen for the signals that bounce off
[18:54] <eroomde> http://www.w5un.net/EME%20Array.JPG
[18:55] <GW8RAK_> Some people say Moonraker are not great, and if you have the money, try a 19ele cushcraft at £239
[18:55] <eroomde> needless to say, you can probably get away without this kind of rig for high altitude ballooning
[18:55] <NigeySWales> bloody hell! .. scuse the french thats mahoosive!!!!!
[18:56] <fsphil> the most important thing for hab'ing is line-of-sight
[18:56] <GW8RAK_> There's an American who uses a surplus 4" gun mounting as a rotator for his dish!
[18:56] <NigeySWales> :o now thats extremely worrying, where did the gun go?! lol
[18:57] <GW8RAK_> 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] <eroomde> it's america
[18:57] <GW8RAK_> From the picturs I've seen, it looks like he has just shoved the dish support down the barrel.
[18:57] <SpeedEvil> eroomde: That looks like it comes from the age of sail.
[18:58] <NigeySWales> lol
[18:58] <eroomde> or one of those world war two radars
[18:58] <GW8RAK_> EME has got considerably easier over the years with low noise preamps and digital signal processing. There was a report a couple of years ago of one station having just a simple 2m beam and relatively low power.
[18:59] <NigeySWales> i was going to pick up the aor that was on ebay but auction ended at 8am :(
[18:59] <eroomde> NigeySWales: whilst obviously buying one initially means you've got something proven and working, they're not that hard to build and it's very much cheaper to do it that way
[19:00] <eroomde> so once you've got one, you could make a weekend project of a huge one
[19:00] <NigeySWales> definately something i'd like to try
[19:00] <eroomde> there are some really good free software programs that generate dimensions and building instructiosn for you when you input the number of elements and so on that you want
[19:01] <GW8RAK_> You could try http://www.g6lvb.com/HomebrewArrow.htm
[19:01] <GW8RAK_> Cheap and easy.
[19:02] <eroomde> Doug Ellison had the receiving distance record with his OTS arrow
[19:02] <NigeySWales> tnx guys i'll take a good look, seems fairly doable with some not to expensive materials
[19:02] <eroomde> for a while anyway
[19:03] <GW8RAK_> I'd certainly recommend wood for the boom. It's easy to work and if varnished or painted it will easily last 10 years outdoors.

[19:09] <NigeySWales> i'm sure ive got a ton more too lol
[19:09] <eroomde> dumb question rate almost always correlates with likelihood of success!
[19:10] <NigeySWales> i was thinking far ahead last night about where i would launch from, im smack bang in the middle of cardiff city center :(
[19:10] <GW8RAK_> In that case I'm guaranteed!
[19:10] <NigeySWales> snap!
[19:11] <eroomde> If you can face the transnational trek to cambridge, you'd be more than welcome to launch at our site
[19:12] <NigeySWales> its certainly possible, definately have to be a weekend though, probably a saturday.
[19:13] <eroomde> suits us
[19:13] <eroomde> lectures during the week
[19:14] <NigeySWales> 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] <eroomde> have you come across our hourly predictor? cuspaceflight.co.uk/hourly-predictions
[19:16] <NigeySWales> oh no, thats new to me, let me take a look...
[19:16] <GW8RAK_> That will provide hours of fun.
[19:16] <eroomde> 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] <eroomde> it's basically a 'week at a glance' for seeing if there's a flight window
[19:17] <eroomde> 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] <NigeySWales> thats an amazing piece of coding right there!

[19:22] <eroomde> jcoxon, rocketboy and I did (about 4 years ago scarily enough jcoxon) some tests dropping parafoilsed vehicles from a tethered balloon
[19:22] <eroomde> it gave up about mid afternoon
[19:24] <jcoxon> eek
[19:24] <fsphil> ooh that's not long
[19:24] <jcoxon> that long ago
[19:24] <fsphil> (the balloon not the years ago ;-)
[19:29] <jcoxon> eroomde, with the current prediction for my saturday floater you'll be well placed to pick up...
[19:29] <eroomde> lol
[19:29] <eroomde> indeed
[19:31] <GW8RAK_> Is there a particular Arduino board which people would recommend?
[19:32] <jcoxon> i personally perfer the 3.3v versions
[19:32] <eroomde> you might find 16k a bit crumbed too
[19:32] <jcoxon> just cause they are easier to inteface with stuff
[19:32] <eroomde> crampt*
[19:32] <GW8RAK_> I don't want to have to learn C, but if I have to for future projects then so be it.
[19:32] <jcoxon> yeah get a atmega328 version
[19:32] <eroomde> but i think all the new ones have at least 32k of flash
[19:33] <jcoxon> eroomde, pub weds night?
[19:33] <eroomde> sure lets
[19:33] <eroomde> somewhere near arundel?
[19:33] <jcoxon> yeah
[19:33] <eroomde> cool
[19:35] <jcoxon> i had a good meal in the swan in arundel about a month ago

[19:36] <jcoxon> not fussed really

[19:37] <NigeySWales> hmm should my new soldering iron have smoke soming from the handle? lol

[19:38] <jcoxon> there*
