[13:33] <phatmonkey> just before I go - any update from james?
[14:18] <Tiger^> hmm
[14:18] <Tiger^> nope
[14:20] <phatmonkey> hope everything's going alright

[15:11] <jcoxon> phatmonkey, yup
[15:12] <phatmonkey> sweeet
[15:12] <phatmonkey> how far did it travel?
[15:12] <jcoxon> though it didn't go "that" high
[15:12] <phatmonkey> ah
[15:12] <jcoxon> not sure i'll know in a bit
[15:12] <phatmonkey> how high?
[15:12] <jcoxon> just about to download the info
[15:12] <jcoxon> got hte pictures though
[15:12] <jcoxon> uploading them now
[15:13] <phatmonkey> nice, ok
[15:17] <jcoxon> here are the first few
[15:17] <jcoxon> i'll do the rest later:

[16:13] <jcoxon> hey all
[16:13] <jcoxon> just popping into post the peg3.kml file
[16:13] <jcoxon> will put lots more up later
[16:14] <jcoxon> max altitude was 19495m at 9.52am GMT
[16:15] <phatmonkey> how many feet is that, hm
[16:15] <phatmonkey> 63k
[16:15] <phatmonkey> less than #1!
[16:15] <phatmonkey> suppose that's better than losing it
[16:16] <phatmonkey> how close did it get to the sea or whatever?
[16:17] malgar (n=malgar@adsl-ull-12-192.47-151.net24.it) joined #highaltitude.
[16:20] <jcoxon> nope no where neer
[16:20] <jcoxon> though close to stansted airport
[16:22] <phatmonkey> sigh, i have the robostix working but still no luck with the gps
[16:22] <jcoxon> oh
[16:23] <phatmonkey> data is definitely getting through, it's just garbled
[16:23] <jcoxon> right speed?
[16:23] <phatmonkey> 4800 baud, yep
[16:23] <phatmonkey> hmm, i might try some others
[16:23] <phatmonkey> might be different from the default for some reason
[16:25] <phatmonkey> serial port is working when i hook up rx and tx, so that's not the problem
[16:27] <phatmonkey> nope, definately 4800 baud, the right amount of data seems to be coming through then
[16:27] <phatmonkey> it's not a baud/parity/whatever problem, gpsd cycles through everything and kicks up a segmentation fault
[16:28] <phatmonkey> gpsd: polling 4
[16:28] <phatmonkey> gpsd: packet sniff finds type -1
[16:28] <phatmonkey> gpsd: polling 4
[16:28] <phatmonkey> gpsd: packet sniff finds type -1
[16:28] <phatmonkey> gpsd: packet sniffer failed to sync up
[16:28] <phatmonkey> gpsd: closing GPS=/dev/ttyS2 (4)
[16:28] <phatmonkey> Segmentation fault
[16:28] <phatmonkey> [root@gumslug:~]#
[16:28] <phatmonkey> and lots of those first two lines
[16:28] <phatmonkey> i guess it's trying to find ASCII/NMEA data but failing
[16:29] <phatmonkey> maybe the gps is not working...
[16:35] <jcoxon> test it on another port?
[16:36] <phatmonkey> what was the other serial port on the waysmall board you gave me?
[16:36] <phatmonkey> i could set that up as a serial console then disable the console on /dev/ttyS0
[16:37] <phatmonkey> HWUART?
[16:37] <jcoxon> yup
[16:37] <phatmonkey> okay
[16:40] <phatmonkey> halright, i'll move it to FFUART
[16:40] <phatmonkey> :|
[16:41] <phatmonkey> it's exactly the same electronically, and STUART is definitely working
[16:42] <jcoxon> ?
[16:42] <jcoxon> i'm confused
[16:42] <jcoxon> i've put all the photos up
[16:42] <jcoxon> now
[16:42] <phatmonkey> ah, nice
[16:42] <phatmonkey> i have it hooked up the STUART on the robostix at the moment
[16:43] <phatmonkey> FFUART is exactly the same electronically, so i don't see why it would be different - both serial ports work fine
[16:43] <jcoxon> and it works?
[16:43] <phatmonkey> it's probably the gps... but i'm not sure what
[16:43] <rocketboy> I have also put some from today at http://randomsolutions.co.uk/personal/launch/
[16:44] <phatmonkey> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/flight/DSCI0145.JPG
[16:44] <phatmonkey> ooh, that's a nice pic
[16:45] <jcoxon> rocketboy, cool
[16:45] <jcoxon> have you looked at the route yet?
[16:45] <phatmonkey> the serial outputs on here are 0 to voltage in (which is 5v), that would be TTL wouldn't it?
[16:46] <rocketboy> wow - those are good pics - nice and level
[16:46] <phatmonkey> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/flight/DSCI0162.JPG
[16:46] <phatmonkey> woah
[16:46] <jcoxon> some aren't though
[16:46] <jcoxon> lots of weird motion blur
[16:47] <phatmonkey> some really nice pics though, well done
[16:48] <phatmonkey> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/flight/DSCI0177.JPG - ouch, i see what you mean by close to stansted - is that stansted?
[16:48] <jcoxon> thanks, but it wasn't just me
[16:48] <jcoxon> yup
[16:49] <jcoxon> but there is a better one :-D
[16:49] <phatmonkey> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/flight/DSCI0179.JPG
[16:49] <phatmonkey> wow!
[16:49] <phatmonkey> aerial plane spotting :D
[16:51] <jcoxon> rocketboy, so is it time to start planning the next one ? :-D
[16:52] HenryHallam (n=H@natreg.pem.cam.ac.uk) joined #highaltitude.
[16:52] <rocketboy> I guess so - I'd like to work on the comms link in the next couple of weeks - I guess I might have it ready for when you get back
[16:52] <HenryHallam> hi gang
[16:53] <phatmonkey> hey
[16:53] <HenryHallam> James what was the url for the photos and kml?
[16:53] <jcoxon> rocketboy, okay cool
[16:53] <jcoxon> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/
[16:53] <jcoxon> right time for me to pack up my room and go home
[16:54] <jcoxon> will chat to you all soon
[16:54] <HenryHallam> thanks
[16:54] <HenryHallam> have a good trip back
[16:54] <HenryHallam> cheers for the jaffa cakes

[16:55] <phatmonkey> niice, bye
[16:56] <phatmonkey> wow, it landed about 20 miles away from me
[16:57] <phatmonkey> suppose i should have helped :D
[16:57] <HenryHallam> hehehe
[16:58] <HenryHallam> getting up at 5 was a bit harrowing but worth it I think, morning launches seem to be a good idea
[17:02] <phatmonkey> haha, yes
[17:02] <phatmonkey> wow, it's easy to see where the jetstream is on google earth isn't it
[17:07] <rocketboy> yes - its an amazing tool - love the 3d
[17:12] <rocketboy> so is that 14300 m? (47,000 ft) ?
[17:14] <HenryHallam> hm
[17:14] <HenryHallam> let me look at the track log
[17:15] <HenryHallam> highest was 19495m
[17:15] <HenryHallam> 64000 ft
[17:16] <rocketboy> wow (must have missed some) - I wonder why the cutdown didn't go off
[17:17] <HenryHallam> something with the gumstix connection, he never tested it connected to the actual cutdown, only with a voltmeter
[17:19] <rocketboy> humm - need to add a continuity test LED
[17:19] <rocketboy> mind you it could be the circuit

[18:29] <rocketboy> near howlett end
[18:29] <rocketboy> 51:59;23N 0:16:30E
[18:31] <icez> it would help if i lived in the UK
[18:31] <icez> :p
[18:32] <HenryHallam> I have an improved KML file of the flight, can DCC it if anyone wants to see
[18:32] <rocketboy> ok

[18:46] <rocketboy> sorry henry i didn't have .kmls listed for DCC - can you send it again
[18:51] <HenryHallam> it could be firewall issues
[18:51] <HenryHallam> I can put it on some webspace if you like
[18:53] <rocketboy> could be (or it could be me) - a web link would be good

[19:06] <malgar2> wait one moment.. pegasus 3 launched???
[19:06] <malgar2> when??
[19:10] <rocketboy> today
[19:11] <rocketboy> at abot 7:30am
[19:11] <icez> malgar! i have a question :|
[19:11] <icez> (for you)
[19:11] <malgar2> wooow cool, why i was not informed? :P
[19:12] <rocketboy> try http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/
[19:12] <icez> malgar2: do you have any of your photoclinometry stuff for the photoclinometry page on wikipedia?
[19:14] <icez> nice flight
[19:23] <malgar2> icez, not in this moment
[19:24] <malgar2> max height?
[19:29] <rocketboy> about 60,000 so im told
[19:31] <malgar2> ft?
[19:31] <malgar2> uhm.. 20km?

[21:19] <defy> did i miss any launches in the last 2 weeks?
[21:23] <icez> pegasus 3
[21:23] <icez> today
[21:23] <defy> oh awesome
[21:24] <icez> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/flight/
[21:24] <icez> :]
[21:24] <icez> 19.495km i heard
[21:24] <defy> nice :D
[21:25] <icez> yeah
[21:25] <icez> there's a kml file too
[21:26] <defy> opening it now...
[21:27] <defy> very cool
[21:41] <defy> well i assume none of my scripts failed then, thats good to know :D:D
[21:50] <icez> haha
[21:51] <icez> "yeah defy, it seems we lost peg3 because of you!"
[21:51] <icez> :/
[21:51] <defy> hahaha
[21:51] <defy> :P
[21:54] <defy> how long ago was it launched? i might have been in the air at the same time it was
[21:54] <defy> 12 hour flights suck =/
[21:54] <HenryHallam> lauched at 0745 GMT today
[21:55] <HenryHallam> n*
[21:55] <HenryHallam> airborne for about 3 hours
[21:55] <defy> sweet
[21:55] <HenryHallam> slightly better KML here: http://www.srcf.ucam.org/~hmh33/peg3.kml
[21:55] <icez> you launched too defy ?
[21:56] <HenryHallam> I think the Pegasus balloon was defective, the colour didn't seem quite right and it burst pretty early
[21:57] <HenryHallam> also the ascent rate seemed quite low, only around 300-400 ft/min despite about 700g worth of excess lift
[21:57] <icez> okay, i think google earth is bugging
[21:57] <icez> right under the kml stuff it says "Dallas - Fort Worth International"
[21:57] <icez> :/
[21:57] <HenryHallam> the flythrough tour is buggy for anything much above ground elevation
[21:57] <HenryHallam> ah could be since we just stole the kml file from somewhere and replaced the coordinates
[21:57] <HenryHallam> let me check it
[21:58] <icez> and then the netherlands up
[21:58] <HenryHallam> try zooming in on cambridge, see if you can see it
[21:58] <defy> very cool, nah no launch yet
[21:58] <icez> you guys launched in that park right?
[21:59] <HenryHallam> it's the playing fields of a college
[21:59] <HenryHallam> there might be a weird buggy bit at the beginning while it was actually on the ground but before the GPS got a good sat lock, it thought it was at 400m altitude
[21:59] <icez> lol
[22:00] <icez> man, that was far though
[22:00] <HenryHallam> is the kml working then?
[22:01] <icez> yeah
[22:01] <icez> goes slowly up, and then zigzags way up, and straight down, then slowly down
[22:01] <icez> :)
[22:02] <defy> kml works for me, looks the same as the other one on the site though :P
[22:02] <icez> hey HenryHallam, which data did you use to make that kml file?
[22:03] <HenryHallam> the logfile from the gumstix on Pegasus, just grabbed the lat lon and alt columns
[22:04] <icez> can I have it?
[22:04] <HenryHallam> I don't have the raw logfile here, James has it
[22:04] <icez> ah
[22:04] <icez> ok
[22:04] <HenryHallam> you can get the lat lon and alt just by looking inside that kml
[22:04] <icez> what unit is it?
[22:04] <HenryHallam> except for some reason in kml files they put lon first then lat
[22:04] <HenryHallam> altitude is in m
[22:04] <HenryHallam> lon and lat in decimal degrees
[22:04] <icez> ok
[22:05] <HenryHallam> btw it's worth getting the new beta google earth if you don't have it, it's a bit nicer
[22:06] <icez> well i'm using the linux-beta
[22:06] <HenryHallam> ah haven't tried that
[22:06] <icez> it isn't as nice as the windows one :(
[22:07] <HenryHallam> oh well I'm sure they will improve it
[22:09] <icez> so I guess you go at the same school?
[22:09] <icez> :?)
[22:09] <HenryHallam> yeah, James does medicine and I'm doing engineering
[22:09] <HenryHallam> Peg3 landed underneath some high tension cables, less than 1km from a really huge power substation
[22:09] <icez> uhoh
[22:09] <HenryHallam> potentially it could have bounced off the HV lines but I doubt we'll ever know for sure
[22:10] <icez> the good thing is that it's alive :)
[22:10] <HenryHallam> need to take pictures more often than just every two minutes!
[22:10] <HenryHallam> yep
[22:10] <HenryHallam> and the radio demonstrator worked very well which is really useful to know
[22:10] <icez> videooo
[22:10] <icez> :)
[22:11] <HenryHallam> it had a 10mW transmitter and Steve (rocketboy) was getting a really good signal for the whole flight, mostly even just with a whip antenna not a directional one)
[22:11] <HenryHallam> -)
[22:11] <icez> cool
[22:11] <HenryHallam> it was sending "PEGASUS 3" in Morse code so it would be pretty easy to get it to send GPS coordinates in Morse
[22:12] <icez> that would be nice
[22:13] <defy> wow really? 10mw worked all the way up to 65000 feet?
[22:13] <HenryHallam> yep and with a good strong signal
[22:13] <defy> cool
[22:13] <HenryHallam> Steve thinks it could easily do 100km if not more
[22:14] <defy> gotta love having the entire fresnel zone free
[22:14] <HenryHallam> you won't get high speed data at that kind of range but you only need a very slow link
[22:14] <icez> well, that can be fixed like the galileo spacecraft
[22:14] <icez> :]
[22:14] <icez> little custom encryption here and there
[22:14] <HenryHallam> lol indeed
[22:15] <defy> yea gps cords and possibly a release cmd would be nice to have at full hieght
[22:15] <HenryHallam> we'll be sure to put a nice long passcode on the release cmd
[22:15] <defy> hehe

[22:18] <jcoxon> henry
[22:18] <icez> uh
[22:18] <jcoxon> don't flood!
[22:18] <HenryHallam> erk sorry
[22:18] <HenryHallam> wrong clipboard
[22:19] <jcoxon> hehe
[22:19] <phatmonkey> hehe
[22:19] <HenryHallam> what I meant to paste was this: http://www.srcf.ucam.org/~hmh33/peg3.kml which is a slightly easier to see version of the KML, James
[22:19] <phatmonkey> what sort of radios were used for pIII? were they reliable? should I get some?
[22:21] <jcoxon> phatmonkey, well
[22:21] <jcoxon> we've learnt quite a bit
[22:21] <jcoxon> stuff the 868mhz
[22:21] <HenryHallam> 406MHz is where it's at
[22:21] <jcoxon> 434mhz is the way to go methinks (do you agree henry?)
[22:21] <jcoxon> haha
[22:21] <HenryHallam> er 434
[22:21] <HenryHallam> yeah whatever it was
[22:21] <phatmonkey> hokay
[22:22] <HenryHallam> same as Traxa uses
[22:22] <phatmonkey> live communication would be so good for the glider
[22:22] <phatmonkey> what sort of antenna?
[22:22] <phatmonkey> ground and payload i suppose
[22:23] <HenryHallam> Yagi for ground (also a rubber whip for when it's within a few miles and you don't need the yagi)
[22:23] <jcoxon> HenryHallam, the whip was pretty damn good to tell the truth
[22:23] <HenryHallam> yeah
[22:23] <HenryHallam> I think Yagi might be useful for longer distances though
[22:23] <HenryHallam> worth having and not too hard to build
[22:24] <jcoxon> true
[22:24] <HenryHallam> what's the name of the antenna on the bottom of the payload?
[22:24] <jcoxon> phatmonkey, you won't get that much bandwidth
[22:24] <HenryHallam> you might at close range
[22:24] <jcoxon> ummm its like a quarter thingy
[22:24] <HenryHallam> or you could at least give it a target coordinate to autonom to
[22:24] <jcoxon> phatmonkey, but it should definitly get gps across
[22:24] <jcoxon> yeah
[22:24] <phatmonkey> yeah, don't need bandwidth
[22:25] <phatmonkey> gps, flight status, attitude, simple stuff
[22:25] <phatmonkey> does uplink work too?
[22:25] <phatmonkey> i guess up is easier than down
[22:26] <jcoxon> well with uplink you can use a much more powerful signal
[22:26] <phatmonkey> yeah
[22:26] <HenryHallam> but you also have a smaller receiving antenna and probably a less capable receiver
[22:27] <phatmonkey> what's the antenna like on the payload? huge things probably won't be practical for the glider
[22:27] <HenryHallam> pretty small
[22:27] <phatmonkey> this sounds fantastic
[22:28] <jcoxon> http://randomsolutions.co.uk/personal/launch/IMG_0370.JPG
[22:28] <phatmonkey> hokay, i have an inverter hooked up to my gps, let's see if this works!
[22:28] <jcoxon> phatmonkey, its basically is a single dangle of antenna with 4 radial bits
[22:28] <jcoxon> 250mm x 250mm will be enough
[22:29] <jcoxon> perhaps across the wingspan?
[22:29] <phatmonkey> yeah
[22:29] <defy> nothing broken on landing?
[22:29] <jcoxon> nope, nothing
[22:29] <phatmonkey> the glider's rather big, we shouldn't have troubles
[22:29] <defy> awesome
[22:29] <jcoxon> the cutdown didn't work
[22:29] <jcoxon> but hey
[22:29] <jcoxon> defy, have you seen the kml of the flight yet?
[22:30] <defy> yup
[22:30] <jcoxon> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/flight/DSCI0112.JPG\]
[22:30] <jcoxon> oops:
[22:30] <jcoxon> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/flight/DSCI0112.JPG
[22:30] <jcoxon> got the moon!
[22:30] <phatmonkey> do you know if that was because of the connection/gumstix or the explosive widget not working
[22:30] <defy> oh thats awesome
[22:30] <defy> got the moon in the shot
[22:30] <jcoxon> not sure
[22:30] <Tygrys> jcoxon: this PATH.jpg thingy is from google earth?
[22:30] <phatmonkey> it's really easy to see where the jetstream is on google earth, amazing
[22:31] <jcoxon> phatmonkey, not sure though probably my programming
[22:31] <HenryHallam> the widget looked undamaged so I suspect something went wrong electrically or in software
[22:31] <Tygrys> yay! the moon
[22:31] <phatmonkey> ooh, it landed about 20 miles from here!
[22:31] <jcoxon> Tygrys, Path,jpg?
[22:31] <jcoxon> yeah i thought that when we collected it
[22:31] <jcoxon> should of given you a call
[22:31] <phatmonkey> ah well
[22:32] <Tygrys> jcoxon: http://randomsolutions.co.uk/personal/launch/PATH.jpg
[22:32] <defy> wonder how hard it would be to get a sunset from that altitude, probably very
[22:32] <phatmonkey> testing this shouldn't be far off, the code is 90% done
[22:32] <HenryHallam> can't be that hard if you take a picture every 2 seconds
[22:32] <defy> hehe
[22:32] <jcoxon> Tygrys, of yeah that is
[22:32] <jcoxon> Tygrys, rocketboy must of screenshotted it
[22:32] <jcoxon> the kml file is on the web if you want it
[22:33] <Tygrys> yeah i got it
[22:33] <jcoxon> HenryHallam, send me the new kml file and i'll update it
[22:33] <phatmonkey> gawd, i've got such a tangle of wires on my desk
[22:33] <HenryHallam> that's how it should be
[22:33] <Tygrys> jcoxon: you used the commercial version of google earth, right?
[22:33] <jcoxon> i didn't
[22:34] <phatmonkey> oh my god!!!! gps works!
[22:34] <phatmonkey> awesome
[22:34] <HenryHallam> sweet
[22:35] <HenryHallam> yeah Tygrys you can make paths like that just by creating a KML file, which is incredibly east (open that one up in Notepad
[22:35] <HenryHallam> )
[22:35] <HenryHallam> easy*
[22:35] <HenryHallam> james, http://www.srcf.ucam.org/~hmh33/peg3.kml
[22:35] <phatmonkey> i must research things properly before i buy, my eyes just skipped over "RS-232 compatible"
[22:36] <HenryHallam> if TTL is easier you can probably rip it apart and tap in before the level shifter
[22:37] <Tygrys> HenryHallam: yeah, i know. it's a markup lang like xml.
[22:37] <jcoxon> ooo google earth on my linux box works amazingly
[22:37] Action: jcoxon is too lazy to unpack his car so doesn't have his apple
[22:37] <Tygrys> google earth just crashed my laptop
[22:37] <Tygrys> ;)
[22:38] <phatmonkey> HenryHallam, ah well, it works now!
[22:38] <phatmonkey> euch, not getting a lock though
[22:38] <phatmonkey> fix even
[22:38] <phatmonkey> oh wait!
[22:38] <phatmonkey> GPSD,P=51.791423 -0.675813
[22:38] <phatmonkey> eee
[22:38] <phatmonkey> ok, now to get the thermopiles working
[22:38] <jcoxon> we know where you are now
[22:39] <phatmonkey> don't come and stalk me :o
[22:39] Action: jcoxon google maps phatmonky
[22:39] <jcoxon> rubbish resolution
[22:39] <HenryHallam> thermopiles??? are you putting an RTG in there?!
[22:40] <phatmonkey> haha
[22:40] <phatmonkey> no, horizon detection
[22:41] <phatmonkey> please don't give me more crazy ideas :o
[22:41] <phatmonkey> http://www.ctie.monash.edu.au/hargrave/horizon_sensing_autopilot.pdf
[22:41] <HenryHallam> ah that's quite clever
[22:43] <jcoxon> HenryHallam, is it possible to measue the path's length on google earth?
[22:43] <HenryHallam> not that I know of, perhaps in the pay version
[22:43] <jcoxon> oh well
[22:44] <jcoxon> no worries
[22:44] <HenryHallam> I could write something to do it from the Excel sheet though
[22:44] <HenryHallam> not very difficult
[22:44] <HenryHallam> http://en.wikipedia.org/wiki/Great-circle_distance use one of these
[22:44] <HenryHallam> for each segment
[22:44] <HenryHallam> then sum them
[22:45] <HenryHallam> also put in a pythagoras term for the altitude delta
[22:45] <phatmonkey> that algorithm i sent you will do it
[22:48] <phatmonkey> First coordinates: 0.097530 52.212685
[22:48] <phatmonkey> Second coordinates: 0.106179 51.938663
[22:48] <phatmonkey> Distance from 1st to 2nd: 30416.705002
[22:48] <phatmonkey> Bearing: 271.808079
[22:48] <HenryHallam> good stuff
[22:49] <HenryHallam> don't forget the altitude though, that'll probably add a good 25% or so to the total length
[22:49] <phatmonkey> yeah
[22:49] <phatmonkey> 30km ish, 20 miles or so
[22:49] <jcoxon> i'll save that calculation for a rainy day :-p
[22:51] <HenryHallam> I bet the total path length is over 80km
[22:58] <jcoxon> HenryHallam, should we airbrush you out of the photos? (considering you weren't "officially" there?
[23:00] <Tygrys> hehe
[23:00] <HenryHallam> hahaha
[23:00] <rocketboy> hey jcoxon - what do you think went wrong with the cut-down?
[23:00] <jcoxon> hmmm not sure
[23:01] <jcoxon> perhaps not enough from the circuit?
[23:01] <HenryHallam> James it's ok, it looks like I did a pretty good job of hiding my face with my phone accidentally anyway
[23:01] <rocketboy> possibly
[23:01] <jcoxon> HenryHallam, hehe
[23:01] <jcoxon> rocketboy, i'll some investigation
[23:02] <jcoxon> maybe put everything back together and trigger it
[23:02] <jcoxon> see if it blows
[23:02] <jcoxon> if it does then it must have been a software issue
[23:02] <rocketboy> yes - probably best - I found a couple more anyway
[23:02] <rocketboy> (don't forget the goggles
[23:02] <rocketboy> )
[23:03] <jcoxon> don't worry i won't
[23:03] <jcoxon> but i'll remotely trigger it :-D
[23:03] <jcoxon> phatmonkey, do i qualify for the front page?
[23:03] <Tygrys> this is called "post flight hardware analysis" or "mission debriefing".
[23:04] <jcoxon> hehe yeah
[23:04] <jcoxon> also you need to include MiHAB 1 as well
[23:04] <jcoxon> that was launched and recovered today
[23:05] <phatmonkey> jcoxon, well of course ;)
[23:05] <phatmonkey> make a new article, then put it under the flight type
[23:05] <phatmonkey> i think... i forget
[23:06] <phatmonkey> section: launches
[23:06] <phatmonkey> there you go
[23:07] <jcoxon> i can't actually remember my login (and i'm not on my mac so it won't remember it for me)
[23:07] <jcoxon> :-p
[23:08] <jcoxon> right i'm off to bed
[23:08] <jcoxon> has been a long day
[23:08] <phatmonkey> jcoxon/something
[23:09] <phatmonkey> i can't change your password, hm
[23:09] <jcoxon> oh i know my password
[23:09] <phatmonkey> i can write it if you want, what do you want there?
[23:09] <jcoxon> where is the login page?
[23:09] <jcoxon> i'll do it
[23:10] <phatmonkey> http://www.ukhas.org.uk/textpattern/
[23:11] <HenryHallam> James I have the MiHAB images, should I put them on my webspace?
[23:12] <jcoxon> please do
[23:12] <jcoxon> i haven't seen them
[23:12] <HenryHallam> they look all funky
[23:12] <HenryHallam> hang on
[23:13] <jcoxon> phatmonkey, i've totally forgotten my password :-p
[23:14] <Tygrys> the BOFH will remember you've forgotten... :P
[23:16] <Tygrys> http://www.srcf.ucam.org/~jac208/pegasus/pictures/pegasus3/flight/DSCI0194.JPG
[23:16] <phatmonkey> jcoxon, can't change the password either!
[23:16] <phatmonkey> try password or drowssap, i might have set that
[23:16] <phatmonkey> hehe
[23:17] <HenryHallam> yep that's the substation alright
[23:17] <Tygrys> yeah
[23:17] <HenryHallam> http://www.srcf.ucam.org/~hmh33/flight_mihab/
[23:17] <phatmonkey> scary
[23:18] <HenryHallam> check out the stunning 2 bits of precision in the position log
[23:20] <jcoxon> HenryHallam, i think they look like paintings
[23:20] <jcoxon> phatmonkey, you better do the posts for me
[23:21] <HenryHallam> yes the early one of the field especially, just like an oil painting
[23:21] <phatmonkey> hokay
[23:21] <jcoxon> need to use nice cameras
[23:22] <HenryHallam> I'm looking at some on eBay at about £45 with a 3MP ccd and weighing about 75g minus batteries
[23:22] <jcoxon> that sounds good
[23:23] <jcoxon> right tis bed time, won't be around tomorrow (taking a day off :-D) so perhaps speak to you all on monday
[23:23] <jcoxon> thanks again HenryHallam and rocketboy for all the help today (oh and thanks defy for the perl scripts!)
[23:23] <HenryHallam> night James, congrats
[23:24] <HenryHallam> no probs, thanks for some good entertainment
[23:24] <phatmonkey> night james!
[23:24] <phatmonkey> great launch, congrats

[23:24] <phatmonkey> i'm looking for some decent, flatish cameras
[23:25] <phatmonkey> sony used to make some flat and long ones, but they use memory sticks, euch
[23:25] <phatmonkey> i would like some nice piccies, but i don't want a huge bulky thing on the glider
[23:30] <rocketboy> what about http://cgi.ebay.co.uk/OREGON-SCIENTIFIC-FlashCam-Digital-Camera-super-thin_W0QQitemZ170007257390QQihZ007QQcategoryZ31388QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[23:32] <rocketboy> I have 5 of these - thats what my pics were taken with today eg http://randomsolutions.co.uk/personal/launch/IMG_0328.JPG
[23:32] <phatmonkey> it needs to be, uh, sort of long rather than flat
[23:32] <phatmonkey> aerodynamic, that's not going to help for looking forwards!
[23:33] <phatmonkey> nice quality for something so small though!
[23:34] <rocketboy> ah - somthing like a pencam
[23:34] <phatmonkey> yeah, but better
[23:35] <phatmonkey> oh well, photography isn't a big issue right now
[23:35] <rocketboy> http://cgi.ebay.co.uk/PenCam_W0QQitemZ180005917330QQihZ008QQcategoryZ170QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[23:35] <phatmonkey> i'd rather get something flying!
[23:35] <phatmonkey> yeah, that sort of thing
[23:35] <phatmonkey> could always bung one of them on for the first few flights
[23:41] <rocketboy> oh well i'm off to bed - cu guys
[23:41] <phatmonkey> night!
