[00:16] <fuzzylugnuts> I'm guessing that if I write a bunch of C code that parses NMEA strings and does crap like that, I can just write the uControler code around what I am doin now?
[00:16] <ShellEvil> What do you mean?
[00:17] <ShellEvil> what's your existing code?
[00:17] <fuzzylugnuts> the GPS parsing/data extraction and packetization code
[00:17] <fuzzylugnuts> in C, using gcc.
[00:17] <ShellEvil> Ah
[00:18] <ShellEvil> you might want to pole Laurenceb_ - he's got some interrupt driven NMEA parser.
[00:18] <ShellEvil> err - poke.
[00:18] <Laurenceb_> hello
[00:18] <Laurenceb_> that hurt :P
[00:18] <fuzzylugnuts> whimp
[00:18] <Laurenceb_> :P
[00:19] <fuzzylugnuts> ├┐the parser its already written, but I have yet to add the uController code that pulls the data in from the serial port and puts it in a string, then starts the parsing...etc
[00:19] <Laurenceb_> its up on the wiki - http://wiki.ukhas.org.uk/code:interrupt_driven_nmea
[00:19] <Laurenceb_> fuzzy: I tried doing it interrupt driven as you can free up a really significant amount of ram
[00:20] <fuzzylugnuts> ok
[00:20] Action: Laurenceb_ loses his email address tonight :-/
[00:20] <Laurenceb_> how can I back up all my inbox?
[00:20] <ShellEvil> :/
[00:21] <ShellEvil> in what email client?
[00:21] <akawaka> Laurenceb_: what kind of server?
[00:21] <Laurenceb_> evolution
[00:21] <akawaka> fuzzylugnuts: main thing to keep in mind with uc code is memory
[00:21] <Laurenceb_> on ubuntu
[00:21] <ShellEvil> Laurenceb_: I dunno - just click 'download all' not 'leave on server' or something?
[00:21] <fuzzylugnuts> so the code within the "ISR(USART_RX_vect)" brackets is executed when data comes in on the serial port?
[00:22] <Laurenceb_> I'm on xp atm, I'd have to reboot to ubuntu
[00:22] <Laurenceb_> fuzzy: yes
[00:22] <fuzzylugnuts> sweet.
[00:22] <fuzzylugnuts> thanks
[00:22] <Laurenceb_> its not tested
[00:22] <Laurenceb_> but the similarly written TSIP one works
[00:22] <fuzzylugnuts> I'm only interested in the uController end of things
[00:22] <Laurenceb_> yeah, I'm sure you could work out any bugs
[00:23] <fuzzylugnuts> what i do with the data behind closed doors is yet to be decided
[00:24] <Laurenceb_> http://www.oucs.ox.ac.uk/email/access/index.xml.ID=body.1_div.3
[00:24] <Laurenceb_> ^ thats what I'm connecting to
[00:25] <ShellEvil> Sounds like you can suck all the email down using any imap client
[00:25] <ShellEvil> or even pop
[00:25] <Laurenceb_> such as outlook?
[00:25] <ShellEvil> yes
[00:25] <Laurenceb_> k
[00:26] <Laurenceb_> fuzzy: dont forget about initialising the uart
[00:27] <fuzzylugnuts> I'm not to that point just yet
[00:27] <fuzzylugnuts> I'll have loads of questions when I start sticking this in the atmega128
[00:27] <Laurenceb_> hehe
[00:28] <fuzzylugnuts> right now I want to make sure I'm not wasting ym time with strncpy.. and other stuff

[00:31] <jcoxon> evening all
[00:32] <fuzzylugnuts> Heya
[00:33] <Laurenceb_> ShellEvil: I'm getting "Plaintext authentication disallowed on non-secure connections"
[00:34] <ShellEvil> play with the authentication options.
[00:34] <ShellEvil> there should be I presume some sort of cryptographic authentication.
[00:34] <ShellEvil> the question is if both sides support it.
[00:35] <Laurenceb_> "GSSAPI authentication failed"
[00:35] <Laurenceb_> my side doesnt support it?
[00:35] <akawaka> use thunderbird
[00:35] <Laurenceb_> I'll reboot to ubuntu
[00:35] <Laurenceb_> brb
[00:36] <akawaka> it has a much safer plaintext mailbox format

[01:17] <fuzzylugnuts> :O
[01:18] <fuzzylugnuts> its amazing how much adding "\0" after strncpy fixes all my problems.
[01:18] <Laurenceb> hmm how can I find recently changed files on ubuntu?
[01:19] <Laurenceb> fuzzy: you using PIC or AVR ?
[01:19] <fuzzylugnuts> AVR
[01:19] <fuzzylugnuts> probably the atmega128
[01:19] <fuzzylugnuts> I have a few of those
[01:19] <Laurenceb> oh yes you said sorry
[01:19] <fuzzylugnuts> no worries
[01:19] <Laurenceb> its rather big :P
[01:20] <Laurenceb> what do you plan to stick on there?
[01:21] <fuzzylugnuts> yeah, I know its way overkill, but I have a nice eval board for that model. Its going to parse the sentences from the GPS and then send the important stuff via morse code to a transmitter.
[01:22] <fuzzylugnuts> I'd like to send it Hell instead, like the MIT guys' transmitter, but thats furhter down the road right now.
[01:23] <Laurenceb> sounds like hell
[01:23] <Laurenceb> :D
[01:25] Action: fuzzylugnuts is turbopuned
[01:25] <fuzzylugnuts> there's some PIC code out there that will help me
[01:26] <fuzzylugnuts> I have a qrp swr meter and dummy load coming to test the hf transmitter, and I can take it in to work to use my oscilloscope if needed
[01:28] <Laurenceb> hmmm I may have an issue with the v2 radio board
[01:28] <fuzzylugnuts> ?
[01:29] <Laurenceb> I soldered in the regulator before the AVR
[01:29] <Laurenceb> avr programmer is 5v, reg is3.3
[01:29] <Laurenceb> will I fry a 3.3v reg by putting 5v on the output pin?
[01:29] <fuzzylugnuts> that I don't know
[01:29] <SpeedEvil> Perhaps.
[01:29] <fuzzylugnuts> try it!
[01:30] <fuzzylugnuts> :D
[01:30] <SpeedEvil> Most are specified for input no higher than output
[01:30] <Laurenceb> if the input pin is floating?
[01:30] <SpeedEvil> It's probably safest to pull the reg.
[01:30] <Laurenceb> surely if they are connected to a battery and the supply is removed... thats the same?
[01:30] <SpeedEvil> Or connect the input to 5V too
[01:30] <Laurenceb> ah
[01:31] <Laurenceb> I could do that
[01:31] <Laurenceb> ok, this will just be a quick hack up to get a serial bootloader onto it
[01:31] <Laurenceb> then I'm done and dusted
[01:32] <Laurenceb> my plan was to solder on the reg after bootloadering the avr... but I got a bit too eager with the iron :P
[01:34] <fuzzylugnuts> thats why I get a little sauced before building stuff
[01:34] <Laurenceb> sauced?
[01:34] <fuzzylugnuts> pissed
[01:34] <Laurenceb> ha ok
[01:35] <Laurenceb> oh well I'd really better get some sleep, cya all
[01:35] <Laurenceb> thanks for the 5v idea

[01:59] <fuzzylugnuts> yay. gps parse code is done.
[01:59] <fnoble> fuzzylugnuts, cool
[02:00] <fnoble> fuzzylugnuts, what are you using for a flight computer?
[02:01] <fuzzylugnuts> for the main one with all the sensors and controls and communication, I use a gumstix+roboaudio(atmega128)
[02:01] <fuzzylugnuts> I'm just starting to get into uControler programing, so I want to use the AVRs for amall lightweight stuff
[02:02] <fuzzylugnuts> like for taking NMEA strings >> morse code to an HF transmitter
[02:02] <fnoble> yeah, but i bet using a gumstix is nice
[02:03] <fnoble> its going to take a lot of work to get our system fully working
[02:03] <fuzzylugnuts> omg it is soooo nice
[02:03] <fuzzylugnuts> so versitile
[02:03] <fuzzylugnuts> http://68.34.212.42/scrap/gps_parse.c
[02:03] <fnoble> cant even write to a mmc card without corruption
[02:03] <fuzzylugnuts> yep
[02:03] <fuzzylugnuts> er
[02:03] <fuzzylugnuts> oh
[02:03] <fuzzylugnuts> ame
[02:03] <fnoble> i mean, we cant yet
[02:04] <fuzzylugnuts> right
[02:04] <fnoble> and many hours have been done on that code
[02:04] <fnoble> :)
[02:04] <fuzzylugnuts> are you using an avr to write to the mmc?
[02:05] <fnoble> an arm7
[02:05] <fuzzylugnuts> ah
[02:05] <fnoble> i think ive got the actual hardware writing now, but wanted to do fat :)
[02:06] <fnoble> but it didnt want to play
[02:06] <fuzzylugnuts> ahh, hehe
[02:07] <fuzzylugnuts> oh man. I found this awesome electronics store today. It has looooooads of stuff
[02:07] <fuzzylugnuts> even a huge selection of legacy eveready batteries
[02:07] <fuzzylugnuts> even one that was 510V
[02:07] <fnoble> wow
[02:08] <fnoble> local to you?
[02:08] <fnoble> man the uk sucks
[02:08] <fnoble> im in quite a big town and weve only got a maplins
[02:08] <fuzzylugnuts> is that like a radioshack?
[02:08] <fuzzylugnuts> yeah, this place is only 15 miles away
[02:08] <fnoble> yeah, only probably less well stocked
[02:09] <fuzzylugnuts> ahh
[02:09] <fuzzylugnuts> I couldn't pass up getting a eveready No. 276
[02:09] <fuzzylugnuts> biggass 9V battery
[02:09] <fnoble> the big ones have most standard widgets but this is small and in town so its mainly just gadgets
[02:09] <fnoble> fuzzylugnuts, what are they used for? lanterns?
[02:10] <fuzzylugnuts> who noes
[02:10] <fuzzylugnuts> : 3
[02:11] <fuzzylugnuts> I'm going to make a little foxmitter and bury it somewhere
[02:12] <fnoble> whats a foxmitter?
[02:12] <fnoble> so a fox diggs it up?
[02:12] <fuzzylugnuts> a little low power beacon that you hide, and then a bunch of bored hams go try and find it
[02:12] <fuzzylugnuts> haha
[02:12] <fnoble> oh i see hehe
[02:13] <fuzzylugnuts> with the transmitter, it should run for 60 days : P
[02:13] <fnoble> was thinking it would be cool to launch a small baloon with a radio bleeper on it and have a foxhunting race
[02:14] <fuzzylugnuts> Yea, there you go
[02:14] <fuzzylugnuts> brush up on your radio-location skills
[02:14] <fnoble> or if we did it here though RocketBoy would win
[02:15] <fuzzylugnuts> haha
[02:15] <fuzzylugnuts> he does that with his rockets?
[02:15] <fnoble> he has made a cool thingy with two arials which does some phase difference magic to tell you which direction something is in
[02:16] <fuzzylugnuts> OOOoh yeah!
[02:16] <fnoble> and yeah he is a really experienced radio operator
[02:18] <fuzzylugnuts> that always helps
[02:19] <fuzzylugnuts> its here in my antenna book
[02:19] <fuzzylugnuts> the Double-Ducky : 3
[02:20] <fnoble> you have a book on antennas?
[02:20] <fnoble> sweet
[02:21] <fnoble> does it have "the big wheel"?
[02:21] <fnoble> as i was looking into using one for a payload but couldnt find much info
[02:22] <fuzzylugnuts> http://www.google.com/products/catalog?hl=en&safe=off&q=arrl+antenna+book+21st+edition&cid=11421437979381667163#ps-sellers
[02:23] <fuzzylugnuts> it has a few HF loop antennas
[02:24] <fuzzylugnuts> *takes a picture of the pages with the double duck*
[02:30] <ShellEvil> For balloons and HF, there seems to be only one logical choice for payload antennas IMO.
[02:30] <ShellEvil> Long wire hanging down.
[02:31] <fuzzylugnuts> http://68.34.212.42/scrap/pg1.jpg
[02:31] <fuzzylugnuts> http://68.34.212.42/scrap/pg2.jpg
[02:31] <fuzzylugnuts> SpeedEvil: I agree
[02:32] <ShellEvil> Though ESD protection is gonna be a bitch.
[02:32] <fuzzylugnuts> ?
[02:32] <ShellEvil> lightning.
[02:33] <fnoble> it would be nice to have something more flat it it was possible though
[02:33] <ShellEvil> Sure.
[02:34] <ShellEvil> Long wire has lots better radiation efficiency though at HF.
[02:34] <fuzzylugnuts> yeah
[02:34] <fuzzylugnuts> a loop would probably do it, though
[02:34] <fuzzylugnuts> for cw
[02:35] <fnoble> when you say long, you mean >1/4 wavelenght?
[02:35] <ShellEvil> >=
[02:35] <fuzzylugnuts> sure, why not a full length 160m dipole?
[02:35] <ShellEvil> For 10MHz
[02:35] <fuzzylugnuts> : 3
[02:36] <fnoble> how does the radiation pattern change when going from 1/4 to 1/2 or to whole wavelength?
[02:36] <fnoble> sorry, i am really not up on radio stuff at all
[02:36] <ShellEvil> AIUI - it goes narrower
[02:36] <fnoble> but you get more efficiency?
[02:37] <ShellEvil> you go from - as you approach a zero sized dipole - some small fraction at the poles having little radiation
[02:37] <ShellEvil> To (as you get longer) more and more being directed outwards along the diameter.
[02:37] <fuzzylugnuts> http://www-antenna.ee.titech.ac.jp/~hira/hobby/edu/em/dipole/index.html
[02:39] <fuzzylugnuts> omg, more hypnotic stuffs: http://www.kettering.edu/~drussell/Demos/rad2/mdq.html
[02:40] <ShellEvil> Something around 2.25 wavelengths looks interesting
[02:41] <ShellEvil> little radiation upwards, strong sidelobes to the side.
[02:41] <fnoble> i dont like all those nodes though
[02:41] <ShellEvil> True.
[02:42] <ShellEvil> Something like 1.25 is lots simpler.
[02:47] <fuzzylugnuts> fnoble: no one bought the electron gun I had on ebay
[02:48] <fnoble> :(
[02:48] <fnoble> try try again i guess
[02:48] <fuzzylugnuts> yepyep
[02:49] <fnoble> or go and secretly break someones electron 'scope or whatever it cme out of :)
[02:49] <fnoble> and then helpfully be on hand to provide a replacement
[02:50] <fuzzylugnuts> haha
[02:50] <fuzzylugnuts> whoops! broke vacuum while operating!
[02:50] <fuzzylugnuts> the electron gun would go *poof*
[02:53] <fnoble> luckily i happen to have a spare in my backpack :)
[02:54] <fnoble> how fortunate
[02:54] <fuzzylugnuts> :D

[12:39] <fuzzylugnuts> I figured a battery solution for the distance flights I'll eventually try: A 19Ah lithium thionyl chloride battery and a small cr123 rechargeable hooked in parallel to the thionyl chloride one through a 300ohm resistor.
[12:40] <fuzzylugnuts> the low current constant drain electronics, like the gps, will be drawn directly off the thionyl chloide, while the high current low duty cycle stuff will be pulled off the rechargeable
[12:43] <fuzzylugnuts> during the transmitter's down time, the thionyl chloride will recharge the cr123
[12:44] <fuzzylugnuts> the trick will be balancing the duty cycles of all that so the cr123 will be fully charged up between transmissions

[13:36] <fnoble> ok
[13:36] <fnoble> so whats the deal?
[13:36] <edmoore> because my other headlamp broke
[13:36] <edmoore> and it is raining like a sh!t
[13:36] <edmoore> and there are no buses on sunday
[13:37] <edmoore> I cannot get to ox
[13:37] <edmoore> and the garage is closed to get a new headlamp
[13:37] <fnoble> you dont have a spare in the toolkit?
[13:37] <edmoore> i left the toolkit at home so I could get my bike in the car to bring here
[13:38] <fnoble> sucks
[13:38] <edmoore> likewise multimeter, which I really could have done with yesterday
[13:38] <fnoble> your car toolkit came with a multimeter?
[13:39] <fnoble> you couldlways hitchike
[13:39] <edmoore> well no, it's a diy toolkit
[13:39] <edmoore> i.e. once i've put together
[13:39] <edmoore> and I keep one of the rapid meters in it
[13:39] <edmoore> among all the other crap
[13:39] <fnoble> ok, you should check the car's built in toolkit
[13:39] <fnoble> they sometimes have a bulb
[13:39] <edmoore> i have yet to discover a built-in toolkit
[13:40] <fnoble> hmm
[13:40] <edmoore> and I have change the cam belt, replaced the exhaust, swapped out the gearbox, and other stuff myself
[13:40] <edmoore> in all my years I have no spotted anything toolkitty
[13:40] <edmoore> but... I couyld try and hitchike. I would ask Sammi but she went to Zante at 6am this morning
[13:41] <fnoble> hehe, depends how keen you are
[13:41] <edmoore> anyway, obvious thoughts about the task at hand, if we commit

[13:42] <edmoore> thatway if (when) verdex falls over in its 300mA glory, nothing flight critical goes with

[21:57] <fuzzylugnuts> Good, its a real nice rifle.

[22:15] <edmoore> but G8KHW is the guy to ask
[22:16] <robert1971> Just be nice to send the data to it via uart or such like and get it transmitted :)
[22:16] <robert1971> Wishfull thinking
[22:17] <fuzzylugnuts> didn't one of you folks make up a transmitter like that?
[22:17] <fuzzylugnuts> the 10mw one?
[22:18] <edmoore> G8KHW, we, and laurenceb have made some like that
[22:18] <fuzzylugnuts> ok
[22:18] <edmoore> just code up the rtty protocol
[22:19] <fuzzylugnuts> yeah
[22:19] <edmoore> and DAC out to a radiometrix

[22:21] <edmoore> we have the normal 2 wheeled one
[22:21] <robert1971> All the toys are coming this week. Radio, helium, gps/gsm tracker. It's like christmas
[22:21] <edmoore> and it's a real arse to drag out to across the fields

[22:21] <edmoore> machinemart catalogue time
[22:22] <robert1971> It looked a bit over kill but a bargin for 65 quid
[22:22] <fuzzylugnuts> very neat
[22:22] <edmoore> oh totally
[22:22] <edmoore> you won't regret buying it
[22:22] <robert1971> Fit nicely in the 4x4
[22:22] <edmoore> especially if you get a large bottle
[22:23] <robert1971> I got a 1.5m on odrder for friday

[22:23] <robert1971> L
[22:23] <robert1971> Getting there
[22:24] <fuzzylugnuts> I have to rent a truck if I want to fly...can't say I like having h2 ina passenger compartment in a vehicle
[22:25] <robert1971> edmoore when you guys wrote to CAA did you give then a story or did you just ask for permission to launch 1kg payload for 6 months
[22:25] <robert1971> them*
[22:26] <edmoore> just explained what we wanted to do
[22:26] <edmoore> they were quite helpful
[22:26] <robert1971> Worth calling them first?
[22:26] <edmoore> basically yes, jsut explain we wanted to fly balloon experiments as and when for 6 months
[22:26] <edmoore> yes
[22:26] <edmoore> that is how we arranged it - by phone
[22:26] <robert1971> Be nice if I cn lauch from field
[22:26] <robert1971> opps
[22:27] <robert1971> Be nice if I could launch from field out side of the house
[22:27] <robert1971> Won't need that trolly to do much work!
[22:28] <robert1971> UKHAS can then have 2 launch options open.
[22:28] <fuzzylugnuts> in idaho, we left the helium tanks in the truck and had a long fill whip.
[22:28] <edmoore> machinemart is just such a lovely place
[22:28] <robert1971> Sound's like a good idea.
[22:29] <edmoore> if I had money to spend....
[22:29] <robert1971> Right I'v got a busy day tomorrow so I'm going to have an early one.
[22:29] <fuzzylugnuts> Ok
[22:29] <fuzzylugnuts> seeya
[22:29] <robert1971> I'v come to the end of my budget for a while too edmoore
[22:30] <robert1971> It's been fun though
