[21:19] <LaurenceB> rocketboy: are you still planning a launch on 7th jan?
[21:22] <LaurenceB> if it's successful would you be interested in putting the payload into my glider?
[21:23] <rocketboy> yes and sure
[21:23] <rocketboy> I seem to be making a bit of progress with the pic - I have it Parsing GPS GPGGA messages OK now
[21:25] <LaurenceB> I've redesigned my code
[21:25] <LaurenceB> I discovered there is a bytematch register
[21:25] <LaurenceB> that compares the byte in the buffer with its contents
[21:26] <LaurenceB> if there is a match it causes an interrupt
[21:26] <LaurenceB> so I set it to 0A ie line feed so the code knows each time a message arrives
[21:27] <LaurenceB> should work better now
[21:27] <LaurenceB> I'm making a board for the autopilot now
[21:28] <mc-> hi rocketboy, I'm sending you a payload, could you launch it on 7th Jan?
[21:28] <mc-> It's a PIC+GPS+Transmitter
[21:29] <mc-> +cutdown
[21:29] <LaurenceB> I'm planning on having a serial interface where the main electronics can control the autopilot using a command set
[21:29] <LaurenceB> mc- : where are you based?
[21:29] <mc-> Surrey
[21:30] <LaurenceB> Cool, Derbyshire, launched anything before?
[21:30] <mc-> no, but had all the bits for ages including balloons etc
[21:30] <mc-> and you?
[21:30] <LaurenceB> what are you using for cut down?
[21:31] <LaurenceB> I launched the MiHAB balloons see the ukhas site
[21:31] <LaurenceB> - on the wiki
[21:32] <mc-> I'm using a FET as the cutdown, but haven't tested it yet
[21:32] <LaurenceB> ? do you get the fet to burn out
[21:32] <mc-> I've got a geofence working on the PIC
[21:32] <mc-> Fet seems to take plenty of current
[21:33] <mc-> using the fet to light an ignitor
[21:33] <rocketboy> mc - sure no problem on the launch 4 you
[21:33] <LaurenceB> Geofence lol is it just a lat long range or more complicated?
[21:34] <mc-> simpler than that, just check the lat/lon in a lookup table
[21:34] <LaurenceB> ah
[21:34] <LaurenceB> I'm using AVRs instead of PICs
[21:35] <mc-> I've heard AVRs are good, but I've got all the kit for PICs now.
[21:35] <LaurenceB> Yes, before I got into ballooning, I only did analogue stuff
[21:36] <LaurenceB> AVRs are easy to get into
[21:36] <LaurenceB> you dont need as much kit and there are some good development tools
[21:37] <LaurenceB> What sort of transmitter are you using, do you have a ham licence?
[21:38] <mc-> yes, have a ham license, but still restricted to 10mW on 434.075MHz
[21:38] <LaurenceB> even at 10mw the ranfe is amazing
[21:38] <LaurenceB> -range
[21:39] <mc-> true, but you need a good ham receiver, do you have a 433MHz receiver?
[21:39] <LaurenceB> no but rocketboy does :D
[21:39] <mc-> rocketboy, what is your transmission protocol on 434?
[21:39] <mc-> 300 baud?
[21:40] <mc-> I've written some code, to beep the lat/lon out
[21:41] <mc-> as morse code
[21:42] <mc-> must go now, and work on more code. I'll read the logs. Bye for now.
[21:43] <LaurenceB> cya
[21:43] mc- (n=mfcastle@cpc4-glfd1-0-0-cust128.glfd.cable.ntl.com) left #highaltitude.
[21:44] <rocketboy> OK - I use 300baud 200Hz shift 8 bit ascii rtty
[21:44] <rocketboy> I'll BBL

[21:55] <jcoxon> evening all
[21:55] <jcoxon> ooo lots of people
[21:56] <LaurenceB> hi there
[21:56] <jcoxon> hey LaurenceB
[21:56] <LaurenceB> back from africa?
[21:56] <jcoxon> yup
[21:56] <LaurenceB> what were you doing over there?
[21:56] <jcoxon> visiting a friend
[21:56] <LaurenceB> have fun?
[21:56] <jcoxon> but on the way i crossed the sahara
[21:56] <jcoxon> yeah really good
[21:57] <LaurenceB> working on pegasus4?
[21:57] <jcoxon> will start tomorrow
[21:57] <jcoxon> i've already got the phone working
[21:57] <LaurenceB> I'm working on a glider
[21:58] <jcoxon> yeah i've read
[21:58] <jcoxon> sounds very cool
[21:58] <LaurenceB> My gps wasn't fried afterall!
[21:58] <LaurenceB> just a bit smashed
[21:58] <jcoxon> hehe
[21:58] <jcoxon> they are pretty tough things
[21:58] <LaurenceB> after MiHAB2 crashed
[21:59] <LaurenceB> the phone was embedded in a potatoe
[21:59] <jcoxon> hehe
[21:59] <jcoxon> any pics?
[21:59] <LaurenceB> everything still works tho
[21:59] <LaurenceB> you are hosting the pics lol
[22:00] <jcoxon> oh right
[22:00] <jcoxon> oops
[22:00] <jcoxon> i've have a proper look then
[22:00] <LaurenceB> theres some good ones
[22:01] <LaurenceB> but its not quite as good as nova1
[22:01] <jcoxon> heard anything from the nova guys recently?
[22:01] <LaurenceB> you can see the millenium dome
[22:01] <jcoxon> since nova 2 they've gone rather dead
[22:01] <LaurenceB> I know nova2 crashed thats all
[22:02] <LaurenceB> I'm just ordering some supplies of rapid electronics
[22:02] <jcoxon> :-)
[22:03] <LaurenceB> I think i'm going to try a glider with gps only
[22:03] <LaurenceB> I've built a mock up on my bike
[22:03] <jcoxon> i reckon thats all you need
[22:03] <jcoxon> rudder controlled?
[22:03] <LaurenceB> yes rudder only
[22:03] <jcoxon> rocketboy, you around?
[22:03] <phatmonkey> hey
[22:04] <jcoxon> hey phatmonkey
[22:04] <LaurenceB> you can cycle around and follow what the rudder is doing
[22:04] <phatmonkey> really swamped with school work and other things, sorry if i haven't been replying to emails
[22:04] <LaurenceB> hi phatmonkey
[22:04] <phatmonkey> xmas holidays start tomorrow though
[22:05] <phatmonkey> hey
[22:05] <jcoxon> phatmonkey, its no problem - i've been rather busy myself
[22:05] <LaurenceB> it good being at uni, I've been back 2 weeks lol
[22:06] <LaurenceB> my tutor has set me work to be posted to him tho
[22:06] <LaurenceB> thats just evil
[22:06] <rocketboy> Hi Jcoxon
[22:06] <jcoxon> i've only got dissertation work
[22:06] <jcoxon> rocketboy, i've got an email from a guy enquiring about the peg III cutdown device - do you mind me sending him your email?
[22:06] <LaurenceB> I've forgotten what your studying
[22:06] <jcoxon> address*
[22:07] <jcoxon> me? - medicine by my part II is biological anthropology
[22:07] <LaurenceB> ah cool
[22:07] <rocketboy> jcoxon no problem
[22:08] <jcoxon> cool - done
[22:09] <jcoxon> absolutely nothing to do with high altitude ballooning
[22:10] <jcoxon> though i did just include it on my clinical school application
[22:10] <LaurenceB> what is biological anthropology then?
[22:11] <jcoxon> human evolution
[22:11] <jcoxon> but with a few other subjects tagged on
[22:11] <jcoxon> such as primates (as they are good models for early humans)
[22:12] <LaurenceB> Hmmm sounds like it could involve lots off different things
[22:13] <LaurenceB> primates are good models of early humans lol I'm glad I'm not an early human
[22:13] <jcoxon> hehe
[22:14] <LaurenceB> *swings from tree branch*
[22:15] <jcoxon> i'm also thinking of doing a nomad 2
[22:15] <jcoxon> this christmas
[22:16] <jcoxon> get a cheap (slower) rc car
[22:18] <LaurenceB> brb
[22:26] <jcoxon> rocketboy, have you done anything with your motorola router?
[22:28] <rocketboy> na
[22:29] <rocketboy> I may use it as a wifi router (surprisingly) as I havn't got one
[22:29] <jcoxon> hehe
[22:29] <jcoxon> probably a sensible use
[22:30] <jcoxon> got the connector you sent
[22:30] <jcoxon> so will attach the gps asap
[22:31] <rocketboy> I still havn't fired that GPS up
[22:32] <jcoxon> nor have i
[22:33] <jcoxon> rocketboy, phatmonkey size...
[22:33] <jcoxon> really worried about this in regard to a glider
[22:35] <rocketboy> I noticed your email
[22:35] <rocketboy> I'm thinking somthing wedge shaped may be smaller/simpler
[22:36] <jcoxon> yeah
[22:36] <phatmonkey> bigger means we can carry more gear (batteries in particular) and fly further
[22:37] <jcoxon> indeed
[22:37] <phatmonkey> and if the parachute is reliable, it's not more dangerous than anything you've already sent up
[22:37] <phatmonkey> ... and i would quite like to use the zagi 60 i used ;)
[22:37] <jcoxon> ooo i don't know - 60 inches is big
[22:37] <phatmonkey> i need to dash for a bit, might be back in 20 minutes or so
[22:37] <jcoxon> much bigger then any payload we've launched
[22:37] <jcoxon> phatmonkey, np
[22:38] <rocketboy> I think a wedge can be made to righte itself
[22:39] <rocketboy> by placing the weight below the centre of pressure - that way you don't need to worry about roll/pitch
[22:40] <rocketboy> a sort of V wing shape - with the weight at the fold
[22:40] <jcoxon> http://mugi.co.uk/evo_plans.php
[22:43] <rocketboy> not really - more like the wings on a liftg body - http://en.wikipedia.org/wiki/Image:X24.jpg
[22:43] <rocketboy> but with less body
[22:44] <rocketboy> I have access to a big sports hall at work - I was going to try some drop tests from the ceiling
[22:44] <rocketboy> try out some different shapes
[22:44] <jcoxon> what were you going to use as material?
[22:45] <rocketboy> styrofoam
[22:45] <jcoxon> cool
[22:45] <jcoxon> oooo one sec - i've just remembered i've got something v.v. interesting
[22:46] <rocketboy> I have made a couple of shapes at home - thse seem to work well - but i just cant find the space to do propper testing
[22:46] <rocketboy> the sports hall seemed ideal
[22:47] <jcoxon> oh damn i've put it in the attic - it was a paper aeroplane kit - very advanced designs
[22:50] <rocketboy> sounds interesting -
[22:51] <jcoxon> will have to dig it out
[22:51] <jcoxon> in regards to this glider what should i be getting on with looking at?
[22:52] <rocketboy> The parachute means we can make the glider quite small and then deploy the chute at landing
[22:52] <rocketboy> well steering seems the big challenge
[22:53] <rocketboy> servos and GPS based steering
[22:54] <rocketboy> or gliding - I'm unlily to be able to do much on that until the new year
