[00:03] <jcoxon> nope
[00:03] <LaurenceB> grrr I might have to use my laptop instead
[00:05] <defy> i see your little coke bottle boat..hehe
[00:05] <defy> but thats all
[00:23] <LaurenceB> there you go
[00:23] <LaurenceB> 30 sec job in 1 hour
[00:28] <LaurenceB> okay i'm off now cya

[11:17] <defy> oh thats right
[11:18] <jcoxon> the software is beginning to annoy me
[11:19] <jcoxon> i've got the phone on my first serial port
[11:19] <jcoxon> however it seems to freeze after sending a sms message
[11:21] <defy> =/
[11:22] <jcoxon> i'll get there - can't do much with the gps till i get an antenna
[11:31] <LaurenceB> I'm off cya

[12:08] <jcoxon> wooohooooo
[12:08] <jcoxon> actually am getting a gps lock!
[12:08] <defy> sweet
[12:09] <defy> when is the next launch date?
[12:09] <jcoxon> 7th
[12:18] <defy> hehe cool
[12:56] <jcoxon> yay
[12:56] <jcoxon> your script seems to work
[12:56] <jcoxon> maybe it wasn't funny nema
[12:56] <jcoxon> nmea*
[13:03] <defy> weird
[13:03] <jcoxon> hmmmm
[13:04] <jcoxon> peg IV keeps freezing
[13:08] <jcoxon> right maybe not :-D
[13:08] <defy> lol, hate that
[13:09] <jcoxon> sorry i meant the script
[13:09] <jcoxon> seems that this gps uses different strings to the ublox on the gumstix
[13:09] <defy> ah true, i didn't really write it to follow any standards
[13:09] <defy> i simply parsed what i saw coming from the gps
[13:09] <jcoxon> nah its cool
[13:09] <jcoxon> i'm going to do the same
[13:09] <defy> hehe
[13:25] <defy> hey jcoxon, on wunderground.com, that model you showed me for 200mb, what do the colos/numbers within the key represent, speed?
[13:25] <jcoxon> no - at the bottom of the map is a key
[13:25] <jcoxon> speed is shown by the wind vectors
[13:26] <defy> yea, the key just lists numbers, but doesn't say what they represent, or i'm missing it
[13:27] <jcoxon> in the yellow box below the key itself
[13:28] <defy> ah i see
[13:30] <jcoxon> the colours also show the speed

[17:49] <jcoxon> hey mc-
[17:49] <jcoxon> received the gps antenna today
[17:53] <mc-> great, hope it works?
[17:54] <jcoxon> well i'm inside so reception is rubbish
[17:54] <jcoxon> but i have got a single sat
[17:54] <jcoxon> which is far better then before
[17:54] <jcoxon> having some issues with power again so aren't in a position to test it outside yet
[17:54] <mc-> What's the signal strength on the 1 sat?
[17:55] <mc-> shall I send my payload to you or rocketboy?
[17:55] <jcoxon> what nmea string gives that?
[17:55] <jcoxon> ummm i don't mind
[17:55] <mc-> GPSV
[17:55] <jcoxon> rocketboy can test it
[17:55] <jcoxon> and i can bring a few bits of polystyrene to package it in on the day
[17:56] <mc-> I'll send it to rocketboy, as he worried about a freq clash
[17:56] <mc-> thanks
[17:56] <mc-> I'm going to try to make it on 7th Jan, where are you likely to be at 11.30-12?
[17:57] <jcoxon> hmmm - probably launching
[17:57] <jcoxon> or having just launched
[17:57] <mc-> from EARS or somewhere in Cambridge?
[17:57] <jcoxon> EARS
[17:57] <jcoxon> though i really haven't heard much from rocketboy recently
[17:59] <mc-> EARS used to be at spackington.com but that's gone now. Do you have a map to get to EARS?
[18:00] <jcoxon> nope :-D
[18:00] <jcoxon> http://www.ears.org.uk/
[18:00] <mc-> thanks
[18:00] <jcoxon> i won't actually have transport as i'll be back at uni
[18:00] <jcoxon> i'm hoping rocketboy will pick me up on the way
[18:02] <mc-> any reason you choose EARS rather than Camb?
[18:02] <jcoxon> cause they already have a NOTAM
[18:03] <jcoxon> so it was just a matter of having it extended
[18:03] <mc-> ahh
[18:03] <jcoxon> and rocketboy offered to sort it out
[18:03] <jcoxon> its nice not being in charge of a launch
[18:04] <mc-> is there lots to sort out?
[18:04] <jcoxon> well a bit
[18:04] <jcoxon> the CAA seem to leave it to the last minute to actually send your permission through
[18:04] <jcoxon> so there is that little panic
[18:05] <mc-> +helium?
[18:05] <jcoxon> then getting helium is an issue
[18:05] <mc-> snap..
[18:05] <jcoxon> i've got a reliable supplier who only really need about 24hrs notice
[18:05] <jcoxon> and they are pretty reasonable
[18:06] <mc-> I could order it if that helps people, and take the paypal payments.
[18:06] <jcoxon> i think rocketboy is on the case
[18:06] <jcoxon> i think he is going to use BOC and have it delivered to his home and drive it up
[18:06] <mc-> I'll send you an email in a sec
[18:08] <jcoxon> oh okay
[18:08] <jcoxon> grrr
[18:08] <jcoxon> my router keeps freezing up
[18:08] <jcoxon> no idea why
[18:10] <mc-> are you powering from mains or batt?
[18:10] <jcoxon> mains
[18:10] <jcoxon> though i might swap adapter
[18:11] <jcoxon> actually its happier on batteries
[18:12] <jcoxon> i think my power supply was playing up
[18:12] <mc-> have you done the usual test, going back to a previous link of code?
[18:12] <jcoxon> well actually i've removed all the code
[18:12] <jcoxon> its running the bare os
[18:12] <mc-> so it's likely to be a h/w problem then..
[18:13] <jcoxon> i reckon its the power supply
[18:13] <jcoxon> i've swapped now to the original
[18:13] <jcoxon> i'll just make it run for a while parsing gps
[18:14] <jcoxon> i've set it up to flash an led like a heart beat
[18:14] <jcoxon> so i can keep an eye on it running
[18:14] <mc-> have you downloaded the free NMEA viewer from visualgps.com?
[18:15] <mc-> sorry visualgps.net
[18:16] <jcoxon> no - i don't have a windows box
[18:17] <jcoxon> its cool - i'm slowly working on a gps parser
[18:17] <jcoxon> hopefully finish it tongith
[18:17] <jcoxon> luckly i've got defy's perl script to help me
[18:17] <jcoxon> oh mc- whats your payload going to be called?
[18:17] <mc-> I've got some C code to parsing GPS, if that's any use?
[18:17] <jcoxon> thanks - its a good learning curve for me
[18:17] <jcoxon> so i'll carry on using perl
[18:18] <mc-> how about a name of rockoon1, that will help the google ranking..
[18:18] <jcoxon> :-)
[18:18] <mc-> rockoon0.1 actually
[18:18] <jcoxon> hehe
[18:18] <jcoxon> its sort of live balloon v1.0
[18:18] <jcoxon> like*
[18:19] <mc-> bbl
[18:20] <mc-> did you see this? http://www.kd7lmo.net/ansr/ansr_32.html
[18:21] <jcoxon> wow
[18:21] <jcoxon> thats high
[18:23] <jcoxon> grr it froze again - time to test with out hte gps
[18:26] <jcoxon> wish i had the terrain of arizona to fly in
[18:26] <jcoxon> would be so much easier :-D
[18:35] <mc-> but they need lots of paperwork to launch rockoons in the US...
[18:35] <jcoxon> more then here?
[18:40] <mc-> I think so, because they have to do environmental and hazard assessments, since 9/11
[18:41] <mc-> and if you're a US citizen, then they have to comply with US law worldwide.
[18:41] <jcoxon> guess they haven't closed the loophole that exists here
[18:45] <jcoxon> hmmm it looks like the gps is causing an issue
[18:47] <mc-> just emailed you my parser..
[18:48] <jcoxon> oh thanks
[18:48] <jcoxon> i think i'm going to leave the router for a while - make sure it doesn't freeze again
[18:48] <jcoxon> just let it flash its led at me for a good hour
[18:48] <jcoxon> then i'll start a fresh adding the gps back in
[18:49] <jcoxon> will bbl
[20:42] phatmonkey (i=nobody@81.2.121.150) left irc: "Ex-Chat"
[21:16] <mc-> jcoxon, has it stopped hanging? I'm hoping you can fly, is there other payloads in your train?
[21:16] <jcoxon> yeah it seems to have stopped hanging
[21:16] <jcoxon> i've moved it to a side desk
[21:17] <jcoxon> and its much happier
[21:17] <mc-> good
[21:17] <jcoxon> perhaps i was knocking something (its not in its case)
[21:17] <jcoxon> rocketboy is probably going to fly in our train
[21:17] <mc-> cool
[21:18] <mc-> what's the total weight?
[21:19] <jcoxon> about 700g
[21:21] <jcoxon> i'm a little worried as i feel i'm a bit behind in construction
[21:23] <mc-> construction of the styrene box?
[21:24] <jcoxon> no the payload in general
[21:24] <jcoxon> the box is pretty much finished
[21:24] <jcoxon> its getting the software to work
[21:24] <jcoxon> also the cutdown
[21:24] <jcoxon> especially if rocketboy is flying as well
[21:24] <mc-> but if you have rocketboy payload, it will transmit the radio, so yours is primarily the SMS?
[21:25] <jcoxon> yup
[21:25] phatmonkey (i=nobody@81.2.121.150) joined #highaltitude.
[21:25] <jcoxon> so really we'll have 2 radios and 1 sms
[21:25] <mc-> has rocketboy got a cutdown?
[21:25] <jcoxon> actually he also has sms
[21:25] <jcoxon> mc-, he is building one
[21:26] <phatmonkey> WARNING: upgrading the wiki, please submit any changes now
[21:26] <phatmonkey> ... and hi guys
[21:26] <jcoxon> hey phatmonkey
[21:26] <jcoxon> changes?
[21:26] <phatmonkey> if you're editing a page
[21:26] <jcoxon> right
[21:27] <mc-> jcoxon, anything I can assist on getting your payload ready?
[21:28] <jcoxon> ummmm, not really - its all little things - i'll get there :-D
[21:28] <jcoxon> thanks for the offer though
[21:28] <jcoxon> is your payload ready?
[21:29] <mc-> I have to build a 434 antenna, and a bit of gluing..and lots more testing..
[21:29] <jcoxon> heh
[21:29] <jcoxon> e
[21:30] <mc-> I have the cutdown firing every minute (a LED lights..)
[21:31] <mc-> but I don't trust my cutdown, especially if it might ruin your flight..
[21:32] <jcoxon> i'd rather have a cutdown that worked to much rather then one that didn't work again
[21:32] <jcoxon> strike again
[21:32] <jcoxon> didn't work
[21:32] <jcoxon> we can always fly another day
[21:32] <jcoxon> if we get the payloads back
[21:33] <mc-> 'if'!
[21:34] <mc-> did my parser make any sense?
[21:36] <jcoxon> yeah - but i found a really nice perl one
[21:36] <jcoxon> which i've adapted
[21:36] <mc-> perl on a router?
[21:37] <jcoxon> yeah
[21:37] <jcoxon> :-p
[21:37] <jcoxon> it is running linux :-)
[21:37] <jcoxon> well its microperl
[21:40] <jcoxon> (rereading - apologies - that wasn't meant to be patronising)
[21:42] <mc-> I wasn't offended, I know a little php, linux and perl are out of my league.
[21:42] <jcoxon> actually defy introduced me to perl
[21:42] <jcoxon> it might have a bit of an overhead but its incredibly easy to read
[21:42] <jcoxon> and much nicer with strings then C (which is what i used to use)
[21:43] <jcoxon> and i've found c++ really hard to get set up on embedded linux toolchains
[21:43] <mc-> I hate pointers in C, and C++ as well.
[21:44] <jcoxon> woohoo
[21:44] <jcoxon> got it logging every string now
[21:44] <jcoxon> now to reduce the number logged - reduce the file size
[21:44] <jcoxon> (its also converting long and lat to decimal
[21:45] <mc-> I must sleep, cya

[22:15] <LaurenceB> see the wiki has been upgraded with some groovy shading
[22:16] <jcoxon> :-)
[22:16] <jcoxon> thanks to phatmonkey - our excellent webhost/webmaster
[22:16] <LaurenceB> and some different arrows and stuff, now lets see if it actually works :-]
[22:17] <LaurenceB> woot the upload thing is above the images
[22:18] <LaurenceB> hopefully my pc will no longer die
[22:28] <jcoxon> LaurenceB, for you plane - where are the wings?
[22:28] <jcoxon> or am i missing something
[22:29] <LaurenceB> I removed them to install the electronics I've put them back on now
[22:29] <jcoxon> oh okay
[22:29] <LaurenceB> Have you seen the new photo I just uploaded?
[22:29] <jcoxon> yup
[22:30] <LaurenceB> the tape on the front was just holding the cut down thing on while the epoxy went off
[22:31] <LaurenceB> -not a proper cut down, just to cut the line to a tow plane if we use that technique
[22:31] <icez> did you put back the propellers too?
[22:31] <icez> :P
[22:31] <LaurenceB> no, one of them got fitted on my boat
[22:32] <icez> ok
[22:32] <icez> i have the exact same plane hanging next to me;)
[22:32] <LaurenceB> I could try putting them back, but it would weigh too much to fly under its own power
[22:32] <LaurenceB> lol it was the cheap one on ebay
[22:32] <LaurenceB> still flew quite good
[22:33] <LaurenceB> a bit too heavy
[22:34] <LaurenceB> I lost control of it when trying to fly it in strong wind and the battery fell out, I couldn't find it and a new one cost more than the plane
[22:35] <icez> hahaha
[22:35] <icez> haven't flown mine yet
[22:35] <LaurenceB> it was fun while it lasted, the wind must have been about 50mph
[22:37] <LaurenceB> you can just make out the servo I glued to the rudder at the back. Theres a small bit of board just before it with some caps to remove interference
[22:38] <icez> how will it move though?
[22:39] <LaurenceB> It has to be lauched somehow
[22:39] <LaurenceB> the idea is to tow it
[22:40] <LaurenceB> with an rc plane, the resistor on the front will cut it lose
[22:40] <LaurenceB> similar technique to the cut downs on my balloons
[22:41] <icez> oh, so that's how you do it
[22:41] <icez> heat up a resistor and burn the rope?:D
[22:42] <LaurenceB> It might be a bit annoying, I really want an rc plane I can add this to, and use a spare channel to turn it on/off
[22:42] <LaurenceB> I've got a huge glow engine plane, but can't fly it - or daredn't
[22:44] <phatmonkey> join a club and get lessons...
[22:44] <phatmonkey> how i learnt anyway
[22:45] <LaurenceB> I would if I wasn't too busy building balloon stuff
[22:45] <jcoxon> oops
[22:45] <jcoxon> i just sent a test text message to the wrong number
[22:45] <jcoxon> oops
[22:45] <jcoxon> hehe
[22:45] <LaurenceB> Its a bit back heavy at the moment
[22:45] <icez> woops :]
[22:45] <jcoxon> it only said test
[22:45] <jcoxon> so it shoudn't be an issue
[22:46] <LaurenceB> I'll add something heavy at the front to bring the c of g forwards a few cm
[22:46] <LaurenceB> like a big bolt
[22:46] <LaurenceB> just have to mind your heads
[22:46] <LaurenceB> :-]
[22:47] <jcoxon> luckly the previous 5 messages with coordinates in them went wrong
[22:47] <jcoxon> or someone would have been very confused
[22:47] <LaurenceB> its lighter than the origional tho
[22:47] <LaurenceB> if they know nmea they could find your house
[22:48] <jcoxon> nah i haven't got a lock yet - its somewhere else
[22:48] <jcoxon> and i've set it up to convert it to decimal to make it easier to use
[22:49] <LaurenceB> I've mainly been playing with my display 3000 module today
[22:49] <jcoxon> :-D
[22:49] <LaurenceB> I made a cursor you can move on the screen
[22:49] <LaurenceB> and a game of pong
[22:50] <LaurenceB> I so want to make a html browser
[22:50] <LaurenceB> you can get mini wifi modules... if I addad one of those
[22:50] <LaurenceB> -added
[22:52] <LaurenceB> Can't get the default font files to work at the moment, but I've traced down a font compiler to use
[22:55] <LaurenceB> should make a cool flight computer
[22:55] <jcoxon> :-D
[22:57] <jcoxon> wooohoooo
[22:57] <jcoxon> Peg IV now works
[22:57] <jcoxon> well it does the basics
[22:57] <LaurenceB> cool
[23:01] <icez> jcoxon, radar reflector?!:)
[23:02] <jcoxon> :-) haven't built one yet
[23:02] <jcoxon> though i'm not sure i need to
[23:02] <LaurenceB> I've done some tests of the plane by running along the street, the new code that reduces the number of interrupts seems to improve the performance, the servo was tuning quite nicely
[23:02] <jcoxon> as rocketboy is making one and we are flying train
[23:02] <icez> jcoxon, well, how would you test it?
[23:02] <LaurenceB> not sure what the neighbours thought tho
[23:02] <jcoxon> hehe you can't
[23:03] <LaurenceB> launch it over area51
[23:03] <icez> yeah!
[23:03] <icez> but they'll probably find the radiowaves from the wireless and phone and stuff
[23:04] <jcoxon> hehe
