[10:31] <juxta> hey russss - I was out camping recently and there were no sources of atificial light for > 100km, the stars were so bright, it was a bit disorienting looking up :)
[10:31] <earthshine_> lucky bastard

[10:32] <juxta> I never really paid attention in that way before
[10:32] <juxta> but it was quite nice
[10:32] <juxta> is it hard to get away from light pollution in the UK earthshine?
[10:32] <earthshine_> yep
[10:33] <earthshine_> there are a few spots in the contry where it is really dark, but you have to drive to get there
[10:33] <earthshine_> we are sch a tiny island with people squeezed into every spot that there is always light pollution
[10:33] <earthshine_> irritating thing is - it isn't necessary - properly shielded lighting could give you perfectly dark skies
[10:34] <fsphil> not to mention save electric
[10:34] <earthshine_> exactly
[10:34] <earthshine_> why the heck streetlights are on after midnight is beyond me
[10:34] <earthshine_> turn them all off - or just have 1 in 10 on
[10:34] <earthshine_> ridiculous
[10:34] <SpeedEvil> LED based ligts with motion detectors
[10:34] <earthshine_> yup
[10:34] <earthshine_> there are lots of solutions
[10:35] <fsphil> I love the 'well it helps stop crime' argument ... well a thief with a torch is going to be a bit more obvious :)
[10:35] <juxta> agreed
[10:35] <earthshine_> exactly
[10:36] <earthshine_> it's all paranoia
[10:36] <fsphil> a lot of the streets in London are very dimly lit
[10:36] <earthshine_> thieves need lights to see - light up your driveway and you make it easy to steal your car
[10:36] <earthshine_> light up your garden and you make it easy for them to raid your shed
[10:36] <earthshine_> etc.
[10:36] <earthshine_> have them in complete darkness and it makes it hard for them - they then need a torch and are therefore obvious
[10:37] <earthshine_> wereas nobody will pay any attention to someone in a lit driveway
[10:37] <juxta> didnt think of it that way before
[10:37] <juxta> but thats a good point :)
[10:38] <earthshine_> people light up their driveways ad gardens due to a misconception that it will prevent crime
[10:38] <earthshine_> when all it does is help the thief to see
[10:38] <juxta> how far away from cities etc do you have to get to be free of light pollution?
[10:39] <SpeedEvil> juxta: It depends - at least 5km to get rid of the worst of it
[10:39] <SpeedEvil> juxta: a fair bit more to get to truly dark skies
[10:39] sbasuita (~sbasuita@unaffiliated/drebellion) joined #highaltitude.
[10:39] <juxta> oh not as bad as I thought
[10:39] <fsphil> we camped out before our balloon launch, about 5km from the nearest town. the sky was fantastic, but still had a hint of orange
[10:39] <juxta> I was thinking 50km, minimum
[10:41] <SpeedEvil> fsphil: you don't really see the orange if it's dark enough - it's just a brigter sky
[10:41] <SpeedEvil> the eye has no colour at low levels
[10:41] <earthshine_> i can drive about 50 miles down to Camber Sands, where it is really dark
[10:41] <earthshine_> there are some nice dark places down in Cornwall too
[10:41] <fsphil> true
[10:42] <juxta> i suppose being in a valley etc would help?
[10:42] <earthshine_> not really
[10:42] <earthshine_> they tend to generate clouds
[10:42] <russss> Galloway Forest Park in scotland is one of the 5 darkest places in the world (on land) though
[10:43] Action: fsphil makes a mental note to visit that next time he's over
[10:44] <fsphil> that's not that far from me, if it wasn't for the bit of water
[10:47] <earthshine_> a light aircraft is flying overhead
[10:47] <earthshine_> and yesterday one crashed due to "unknown reasons"
[10:47] <earthshine_> and they think it might have been the ash
[10:48] <earthshine_> There is no way i'd fly a light aircraft unless it was 100% safe to do so

[10:53] <fsphil> was just talking to my mum, says a light aircraft flew over here yesterday
[10:54] <SpeedEvil> earthshine: it is moderately easy to fly a light - piston - aircraft safely.
[10:54] <fsphil> I hope they at least give it a good inspection after they land
[10:55] <SpeedEvil> The manifold pressure will give a very good idea of the air filter state
[10:56] <russss> it's only controlled airspace which is closed
[10:56] <russss> the ash is really only above FL240 or so
[10:57] <russss> UKIP were flying a banner around Romsey yesterday
[10:57] <SpeedEvil> I'd think they'd be really happy about no foreign flights
[10:57] <russss> haha

[11:25] <earthshine_> surely you could get around that by communicating with another HAM, but having your payload listen in? ;)
[11:26] <SpeedEvil> you are communicating with a licensed operator - yourself.
[11:27] <russss> well, that's debatable considering that you're not licensed to transmit from the air
[11:27] <earthshine_> the air bit is just receiving
[11:27] <russss> yeah

[15:00] <Lunar_Lander> jcoxon I found the "Communication Protocol" page
[15:01] <Lunar_Lander> is that what we need to get GPS via the radio link?
[15:02] Nick change: jonsowman_away -> jonsowman
[15:02] <Lunar_Lander> can you help me please?
[15:04] <DanielRichman> Lunar_Lander, what's the problem?
[15:04] <jcoxon> Lunar_Lander, ummm not really
[15:04] <jcoxon> thats teh format we send the data down the radio link
[15:04] <jcoxon> the flight computer reads the data from the gps converts it into a different format and then sends it over the radio
[15:05] <Lunar_Lander> I finally want to get how to get the GPS to downlink data
[15:05] <Lunar_Lander> if we can't get that, we only can have a mere beacon signal
[15:05] <DanielRichman> you will need a microcontroller of some sort
[15:05] <Lunar_Lander> yes
[15:06] <DanielRichman> have you chosen one?
[15:06] <Lunar_Lander> I have a friend who is an electrician
[15:06] <Lunar_Lander> wait
[15:06] <Lunar_Lander> he gave me a model number
[15:07] <Lunar_Lander> ARM7TDMI-S Microcontroller
[15:07] <jcoxon> oh cool an ARM7
[15:07] <jcoxon> so yeah the arm7 will read teh gps data and then convert it to a different format to be sent via the radio
[15:07] <Lunar_Lander> ah
[15:07] <jcoxon> the example on the wiki is only a suggestion
[15:08] <Lunar_Lander> he said that he used that model while hanggliding
[15:08] <DanielRichman> yes, essentially you need to attach the gps data out to one of the mcu's uarts
[15:08] <Lunar_Lander> he wired a temp. sensor to it and so on
[15:08] <Lunar_Lander> ah
[15:08] <DanielRichman> then the radio to another uart ot gpio (bit bang)
[15:08] <Lunar_Lander> yes

[15:58] <fsphil> small amount? what are they doing with it?
[15:59] <Lunar_Lander> they are cooling their magnets with it
[15:59] <Lunar_Lander> they research big biological molecules with magnetic resonance spectroscopy
[15:59] <Hiena> Lunar_Lander, that case, would you ship me 3 or 400 cubic meter?

[16:03] <Lunar_Lander> oh

[16:09] <Lunar_Lander> cool
[16:13] <DanielRichman> jcoxon, I was reading the chat log on that stream from what looks like to be the last launch: dl-fldigi is certainly liked over there
[16:13] <jcoxon> oh yes
[16:13] <jcoxon> taken a bit of persuading though
[16:13] <DanielRichman> :P
[16:13] <juxta> Lunar_Lander: if that helium is from your phyics department, it will probably be lab grade helium, not regular balloon gas - even better :D

[16:14] <Lunar_Lander> yeah
[16:14] <Lunar_Lander> they have it in Liquid form :)
[16:15] <jcoxon> DanielRichman, just added a new picture to the guide to tracking page regarding making sure that the enable detection and extraction box is ticked
[16:16] <jcoxon> as that seems to be an issue with the old version
[16:17] <juxta> jcoxon: I forgot to tick it last time until half way through chasing the balloon :)
[16:17] <DanielRichman> jcoxon, that box is in the config window for "version 2.0" (github)
[16:17] <DanielRichman> but as far as I can tell it is neither used nor does anything
[16:17] <fsphil> I didn't have it ticked, strings where being uploaded fine
[16:18] <fsphil> I actually meant to ask about it but didn't get time
[16:18] <juxta> hey fsphil, congrats on the launch yesterday
[16:19] <jcoxon> yeah i though i've made it on by default
[16:20] <jcoxon> however i think if you've run fldigi previously it uses the config file instead
[16:20] <fsphil> thanks juxta! was a great day - will definitely be doing it again

[17:24] <DanielRichman> using the CHDK shoot command, the flash goes off, screen black for ~12 seconds, flash again at the end, yet it's only taken one photo
[17:24] <jonsowman> are you using "shoot_full"?
[17:25] <DanielRichman> i'm just using the shoot command
[17:26] <DanielRichman> I'll retry using click "shoot_full"

[20:38] <DanielRichman> sbasuita, yeah but unless they get the 817 it's not exactly going to be car convenient

[22:11] <Futurity> Hi, Does anyone know the Icarus version that was launched yesterday?
[22:19] <Upu> 2 I think
[22:22] edmoore (~ed@pluto.trinhall.cam.ac.uk) left irc: Quit: edmoore
[22:22] <earthshine> crappy WMV format
[22:23] <Futurity> Icarus III v2, or Icarus II V?
[22:24] <Futurity> also do you know if the tracker times are GMT not BST? I'm just uploading the burst video etc to youtube you see
[22:25] <Upu> II V
[22:26] <Upu> Not sure on the times
[22:26] <rjharrison> Hey Futurity great video
[22:27] <rjharrison> Icarus II Launch 6
[22:27] <Futurity> thanks
[22:27] <Futurity> cool
[22:27] <Futurity> thanks rob just putting together the video for Youtube
[22:27] <Futurity> imported natively
[22:27] <rjharrison> Awsume
[22:30] <Lunar_Lander> good night
[22:30] <Futurity> so hopefully yhis zoomed in video will show more detail

[22:39] <Futurity> Hi Rob
[22:39] <Futurity> are the time in the tracker GMT or BST?
[22:40] <Futurity> must be GMT ;)
[22:40] <Futurity> from launch time
[22:41] <rjharrison> Launch was at 14:10 BST
[22:48] <Futurity> yep, worked it out from the launch time stamp
[22:48] <Futurity> btw has anyone tried attaching a wireless camera to the bottom of the payload?
[22:48] <Futurity> I have a spare one and its very light indeed
[22:49] <Futurity> and smaller than a 9v battery
[22:49] <Futurity> has sound as well
[22:49] N900evil (~Speedevil@tor/regular/SpeedEvil) joined #highaltitude.
[22:49] <Futurity> wondered if it would be worth trying
[22:51] <DanielRichman> wireless camera?
[22:51] <DanielRichman> what type of wireless?
[22:51] <Randomskk> 2.4ghz most likely
[22:51] <Randomskk> maybe 868
[22:51] <DanielRichman> Oh, wifi wireless?
[22:52] <Randomskk> Futurity: the issue is receiving it since their supplied receivers tend to have shit sensitivity and often no way of attaching a decent antenna, and amateur radio receivers won't work
[22:52] <Randomskk> DanielRichman: usually analogue
[22:52] <DanielRichman> mmm
[22:52] <DanielRichman> Futurity, fsphil found and interfaced with a very small camera, although was unable to downlink whole pictures successfully (maybe will be perfected in a later launch)
[22:53] <Futurity> this transmitter is more of a pcb with a ccd stuck on it
[22:53] <Futurity> i'm sure we could hook up a better aerial
[22:53] <Futurity> but reception would be an issue i admit that
[22:54] <Randomskk> they also tend to have very high baud rates - streaming video, not just photos - and so are very sensitive to noise
[22:54] <Futurity> not wifi, tv sender frequency i guess (analogue)
[22:54] <Futurity> i.e. noise (not digital noise) from poor reception
[22:54] <Randomskk> yea.
[22:55] <Randomskk> basically those cameras are a bit noisy when used ten meters away
[22:55] <Randomskk> you will struggle to get decent reception once they are aloft and a long way away
[22:55] <Randomskk> even with an antenna on the receiver, which may or may not be easy to do
[22:55] <Randomskk> the receiver is still not very sensitive or high quality, most of the time
[22:56] <Futurity> yep and if the frequency drifts (as they typically do) then i'll pickup nothing at all
[23:07] Upu (~Upu@ubn.upuaut.net) left irc:
[23:09] <fsphil> is there such a thing as a 2.4ghz pre-amp?
[23:09] <fsphil> to overcome a deaf receiver?
[23:09] <N900evil> yes

[23:24] <Futurity> uploading the Icarus launch now
[23:31] <Laurenceb> Randomskk: what mosfets did you use on your BESC ?
[23:31] <Laurenceb> Futurity: your video was pretty impressive, I was thnking ofr a rockoon launch itd be handy
[23:31] <Laurenceb> can you control the zoom electronically?
[23:32] <Futurity> now this is a cheap Canon Powershot SX1 IS
[23:32] <Futurity> *no
[23:32] <Futurity> you could always take one apart and create your own interface
[23:32] <Futurity> using a telescope may be better
[23:33] <Laurenceb> using a telephoto lens or something?
[23:33] Action: Laurenceb is a photo noob

[23:34] DanielRichman (~DanielRic@unaffiliated/danielrichman) left irc: Remote host closed the connection
[23:35] <Futurity> it has a build in 20x zoom lens
[23:35] <Futurity> not sure the focal length of it
[23:36] <Laurenceb> oh right - doubly impressive
[23:36] <Futurity> it also has Image stabalisation
[23:36] <Futurity> good little camera
[23:36] <Laurenceb> so you could turn down the zoom ?
[23:37] <Futurity> turn down?
[23:37] <Futurity> i zoomed full into the balloon when it burst
[23:37] <Laurenceb> yeah, so turn down as the rockoon launches
[23:38] <Laurenceb> pretty useful
[23:38] <Futurity> oh yes
[23:38] <Futurity> i've just uploaded the wide agle shoot or the launch
[23:38] <Futurity> to youtube i mean
[23:38] <RocketBoy> Futurity: Was the tripod anything special - it seemed smooth - or was that the IS
[23:39] <Futurity> very cheap tripod
[23:39] <Futurity> it does has IS, but its the tripod that keeps it so steady
[23:40] <SpeedEvil> have you worked out the slant range yet?
[23:41] <SpeedEvil> or alternatively, what angle up was it pointing? 30 degrees? 45?
[23:41] <RocketBoy> slant range was 49.8Km by my calculations
[23:42] <SpeedEvil> 50km, 20m, so half a milliradian I guess
[23:43] <RocketBoy> (38.9Km Downrange - 31.2Km Up)
[23:43] <SpeedEvil> was it an iridium flare?
[23:43] <Futurity> video footage of a high altitude balloon bursting on the edge of space at an altitude of 31.228 km (19.4 miles). The balloon was also 37km (23 miles) down wind.
[23:44] <Futurity> the horizontal distance most likely is wrong as i used a car routing program
[23:45] <RocketBoy> I used google earth (and the apogee lat/lon from the logs)
[23:45] <Futurity> cool so your value is far more accurate
