[00:00] <n900evil> This is all theory, I've not yet done motor driver
[00:00] <Randomskk> or VFBGA, hah
[00:01] <Darkside> take a look at the XMegas :D
[00:01] <Randomskk> disappointingly both the VFBGA and DRQFN are 5mm by 5mm, the same size as my current QFN ATmega168
[00:01] <Darkside> awesome chip is awesome
[00:01] <Randomskk> awesome, and incredibly difficult to source and more expensive :P
[00:01] <Randomskk> this 324 has 6 PWM channels apparently
[00:02] <Darkside> Randomskk: lol
[00:02] <Darkside> not hard to source at all
[00:02] <Darkside> sparkfun has a breakout board for one
[00:02] <Randomskk> oh? DanielRichman here was having epic trouble
[00:02] <Randomskk> breakout board isn't much use though
[00:02] <Darkside> why not?
[00:02] <Darkside> apply power, solder on some pin headers
[00:02] <Randomskk> probably bigger than my entire pcb as it stands
[00:02] <Darkside> not hard
[00:02] <Darkside> hehe
[00:02] <Darkside> farnell stocks the chips too
[00:03] <Randomskk> some of them

[00:03] <Randomskk> I guess DanielRichman must have designed around some of the ones they don't
[00:03] <Randomskk> about half the xmegas on farnell (UK) are "awaiting delivery"
[00:03] <Darkside> heh
[00:04] <Darkside> i have an atmel xplain board
[00:04] <Randomskk> n900evil: where did you learn all the theory for it from?
[00:04] <Darkside> only problem with it is the lack of free IO pins

[00:18] <Randomskk> I see. it does indeed.
[00:18] <Randomskk> this is what I get for using a MEGA8 symbol in eagle: pin compatible, but extra goodies not labelled
[00:19] <Randomskk> but I actually have enough to, say, PWM all six FETs
[00:19] <Randomskk> or PWM three, and do a charge pump
[00:20] <Randomskk> there's OC0A, OC0B, OC2A and OC2B for 8bit, and also OC1A and OC1B for 16bit, and both A and B can run on different compares (though same timer prescaler)
[00:21] <Randomskk> I wonder if I could use the analogue comparator to do zero crossing detection
[00:21] <Randomskk> rather than ADCing
[00:21] <Randomskk> thing is, how would I combine the three phases

[09:13] <fsphil> afraid not - tempted to get one though
[09:13] <m1x10> I just finished its soldering
[09:13] <m1x10> and stacked arduino/gsm shield/gps shield
[09:13] <m1x10> but both shields use pins 2/3
[09:13] <m1x10> by default
[09:14] <m1x10> but gps shield has support to use other pins than default 2/3
[09:14] <m1x10> and I try to figure out how you wire it so it does not use 2/3 and uses eg 6/7
[09:16] <fsphil> are there any jumpers or switches?
[09:17] <m1x10> no
[09:17] <m1x10> look

[09:19] <fsphil> http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=173
[09:20] <fsphil> look for the solder jumper bit
[09:20] <m1x10> oh, wait to read it
[09:21] <m1x10> Solder Jumpers: These jumpers, when disabled (solder removed), will disconnect the GPS communication lines (TX and RX) from the Arduino. This allows for the user to connect any digital line to the GPS communication lines.
[09:22] <m1x10> solder removed?
[09:24] <fsphil> I can't really see in the picture -- is it soldered in yours?
[09:25] <m1x10> I think so
[09:25] <m1x10> so I have to unsolder them ?
[09:25] <m1x10> both jumpers
[09:25] <m1x10> ?
[09:26] <fsphil> seems so, then solder a wire between the rx and tx to the pins you want to use
[09:26] <m1x10> omg why they didnt put the usual jumpers....
[09:27] <fsphil> cause not many people need to use other pins :)
[09:27] <m1x10> fsphil you mean rx/tx of the line near to voltage pins. right?
[09:28] <m1x10> yeah im the special guy who just wants a gsm/gps module :)
[09:29] <fsphil> I'm not sure which pins

[11:19] <m1x10> the regulator of arduino its written that it works best when accepting 9V-12V
[11:19] <m1x10> less than 9 or more than 12 make it word bad

[11:37] <m1x10> 1200mAh though
[11:37] <fsphil> it's probably the most you'll get from a pp3 battery
[11:37] <m1x10> yeah
[11:38] <m1x10> how can I calculate the power consuming?
[11:38] <m1x10> I know that gps/gsm consume
[11:38] <m1x10> the*
[11:38] GeekShadow (~Antoine@reactos/tester/GeekShadow) joined #highaltitude.
[11:41] <fsphil> divide the power consumption in mA by 1200
[11:41] <fsphil> to get the number of hours it will last
[11:42] <m1x10> 44mA from gps
[11:42] <fsphil> no wait, that's wrong
[11:43] <fsphil> the other way around
[11:43] <m1x10> gsm: Idle mode: <7.0mA, Communication mode: 350 - 2000 mA
[11:43] <fsphil> no average for the gsm?
[11:44] <fsphil> it's probably idle most of the time
[11:44] <m1x10> Communication mode: 350 mA (average,GSM)
[11:44] <m1x10> and yes it will stay average
[11:44] <m1x10> sorry idle
[11:45] <fsphil> so guess half way, 180 ma
[11:45] <m1x10> so 7+45=52mA every second
[11:46] <m1x10> and 350+45=395mA for each sms
[11:46] <m1x10> ok thats wrong how i calculate it
[11:46] <m1x10> but its quite near to actual
[11:47] <m1x10> so, if just keep it idle
[11:47] <m1x10> its 1200/52=~23
[11:47] <fsphil> what about the microprocessor? it'll be using some power too
[11:47] <m1x10> oh lol yeah
[11:47] <m1x10> i put most parts of avr in sleep mode though. like spi/twi/adc and more
[11:48] <m1x10> I think the best way is to take the battery and test it
[11:48] <m1x10> no reason for calculations.
[11:49] <fsphil> I think you should get at least 3 hours from the pp3
[11:49] <fsphil> probably a lot more if it's idle most of the time
[11:49] <m1x10> thats What I believe too
[11:49] <m1x10> I tell you a 5 hours its possible
[11:49] <m1x10> if I will send about 20 sms

[21:09] <fsphil> Upu, you could tie the camera to the neck of the balloon, looking down on the payload from above

[21:11] <RocketBoy> pics from the bello mondo 1 flight - http://www.flickr.com/photos/52455043@N03/sets/72157624579858395/ - some interesting ones with nice shots of the moon low in the sky

[21:15] <m1x10> RocketBoy, this payload got 3 cams?
[21:15] <RocketBoy> no a single camera and a servo
[21:16] <m1x10> yeah best
[21:16] <m1x10> but u need to open a big whole in payload
[21:16] <m1x10> ?
[21:17] <RocketBoy> the pics of the payload are at the beginning - big but not huge
[21:17] <m1x10> ok I will check it. I just headed for the space photos :):)
[21:17] <RocketBoy> certainly less weight than 3 cams
[21:17] <m1x10> y
[21:17] <m1x10> which canon?
[21:18] <m1x10> can u show me a link to the servo?
[21:18] <RocketBoy> the usual A560 methinks
[21:19] <RocketBoy> actually no - looks different
[21:20] <fsphil> Fujifilm A235 according to flickr
[21:21] <RocketBoy> certainly good pics - some of the best I have sen
[21:21] <RocketBoy> seen
[21:21] <m1x10> y
[21:21] <m1x10> im interested in the servo
[21:22] <m1x10> is it from sparkfun ?
[21:23] <RocketBoy> I don't expect so - it was a standard RC servo methinks
[21:29] Hiena (~Hiena@ left irc: Quit: -=Got bored from the net. Gone blowing up things.=-
[21:32] <RocketBoy> i'm the guy in the red teeshirt BTW
[21:33] <m1x10> heh
[21:33] <m1x10> u r big !
[21:33] <m1x10> i mean I was expecting a kid!
[21:33] <m1x10> haha
[21:35] <fsphil> love the picture of the balloon exploding
[21:36] <fsphil> excellent work
[21:38] <RocketBoy> yeah - thats rather lucky - the best pictures of the moon are in the shots just before burst - small - but quite good when you zoom in
[21:39] <RocketBoy> m1x10: I'm just a big kid at heart :-)
[21:39] <m1x10> heh RocketBoy
[21:40] <m1x10> RocketBoy, is this servo a good one? http://www.sparkfun.com/commerce/product_info.php?products_id=9064
[21:41] <RocketBoy> something like that one yes
[21:41] <m1x10> how do u connect the servo's wire to arduino
[21:41] <m1x10> ?
[21:42] <fsphil> directly to one of the pwm outputs I think -- thats how I did it with the avr anyway
[21:42] <fsphil> though I found it very jumpy
[21:42] <m1x10> the other 2 pins are for what?
[21:42] <fsphil> power
[21:42] <m1x10> oh yeah
[21:42] <m1x10> so vcc/gnd/pwm
[21:43] <fsphil> yep
[21:43] <m1x10> that will be included in my next order :)
[21:44] <m1x10> and u just send different values to turn it from one way to other?
[21:45] <m1x10> fsphil do u have a sample code?
[21:45] <fsphil> the angle it sits at depends on the pwm -- the duty cycle I believe
[21:46] <fsphil> for the avr, not sure if you can use it on the arduino
[21:46] <m1x10> why? arduino got 6 pwms
[21:47] <fsphil> they might have their own library functions to do it - my code writes directly to the registers
[21:47] <fsphil> http://www.arduino.cc/playground/ComponentLib/Servo
[21:48] <fsphil> Seems to be a library written for it already
[21:48] <RocketBoy> basically you need to make a pulse between 1 and 2ms every 20ms - the length of the pulse determines the position
[21:49] <earthshine> Guys i'm reading data from an SCP1000 pressure sensor and it is reading 0.988 atmospheres
[21:49] <earthshine> Doe sthat sound right to you?
[21:50] <RocketBoy> yeah - i guess you are in a low pressure area right now
[21:51] <RocketBoy> have a look at the weather forecast
[21:51] <fsphil> http://www.eldoradocountyweather.com/forecast/UK-Ireland-Currents/uk-current-barometric-pressure.html
[21:51] <fsphil> guessing that 1000 = 1 atmosphere, 0.988 would seem a bit on the low side
[21:52] <earthshine> i'm in Orpington, Kent

[21:53] <fsphil> ah no: one standard atmosphere is exactly equal to 1013.25 hPa
[21:53] <earthshine> it says 100065 Pa
[21:56] <RocketBoy> yeah - so should read about .996
[21:56] <RocketBoy> based on 1009mb

[22:16] <RocketBoy> jiffe: not sure but I'd be surprised if it wasn't the usual energizer lithiums
[22:18] <jcoxon> does anyone want a fsa03 breakout board?
[22:19] <jcoxon> I've got 10
[22:19] <fsphil> o/
[22:19] <RocketBoy> sure - I'll take a couple
[22:19] <jcoxon> the thing is now the fsa03 is a challenge to find
[22:19] <Randomskk> some lovely photos from that bello mondo 1
[22:20] <RocketBoy> oh - why
[22:20] <jcoxon> earthshine doesn't stock them now
[22:20] <jcoxon> and i ordered the last 2 from sequioia tech
[22:20] <jcoxon> not sure there is a uk distributer
[22:21] <RocketBoy> I thought there was a UK sales outlet
[22:22] <RocketBoy> I was in tought with someone in the UK when they first came out
[22:22] <RocketBoy> tough
[22:22] <RocketBoy> touch
[22:22] <RocketBoy> Ill trawl my emails
[22:23] <jcoxon> RocketBoy, http://www.sequoia.co.uk/shop/product.php?p=807
[22:23] <jcoxon> though i've ordered the 2 they claim to stock
[22:27] <Upu> fsphil could do yes :) Looking at this : http://www.dogcamsport.co.uk/mini-dvr-2-helmet-camera.html
[22:27] <RocketBoy> So If I stocked them would they sell?
[22:27] <Randomskk> earthshine found that they didn't
[22:29] <fsphil> Upu, that looks brilliant. the wide angle lens should give some pretty dramatic images
[22:29] <Upu> so sling it out on a boom and the pictures should have something that none of the others have
[22:29] LazyLeopard (~irc-clien@chocky.demon.co.uk) joined #highaltitude.
[22:29] <Upu> the actual payload all sat there :)
[22:30] <RocketBoy> I'm well impressed how macmail has indexed my mail - searches are blindingly fast in comparison with microsoft mail
[22:31] <Randomskk> tbh google
[22:31] <Randomskk> searches are both blindingly fast and work on my very slow netbook
[22:31] Action: Randomskk whores his email to google
[22:33] <fsphil> Seeing the payload with the horizon in the background should be pretty neat
[22:34] <fsphil> I loved the images of the Rosetta probe as it passed mars, could see the spacecraft itself with mars below
[22:35] <RocketBoy> humm - sequoia still say they have 2 in stock - they need a better inventory system
[22:35] <jcoxon> RocketBoy, i think the big issues is the lack of a breakout
[22:36] <jcoxon> i can get 10 pcbs for 22 US dollars
[22:36] <RocketBoy> so if I sold them together
[22:36] <RocketBoy> ?
[22:36] <jcoxon> yeah i reckon so
[22:37] <RocketBoy> got a link to the breakout?
[22:37] <jcoxon> the breakout just makes it nice standard 0.1" pins, adds an led and a push button
[22:37] SpeedEvil1 (1000@tor/regular/SpeedEvil) joined #highaltitude.
[22:37] <jcoxon> none of hte made pcb -can't find the camera cable
[22:37] <jcoxon> teh schematic is : http://www.flickr.com/photos/jcoxon77/4871446692/
[22:37] <jcoxon> let me find the cable
[22:38] <fsphil> I soldered cables to one of my fsa03's ... wish I'd waited to be honest :)
[22:38] <jcoxon> i did that as well on my latest
[22:38] <jcoxon> oh and a backup battery
[22:39] SpeedEvil (~user@tor/regular/SpeedEvil) left irc: Ping timeout: 276 seconds
[22:39] <fsphil> I skipped the battery - it gets a lock pretty quick even without it
[22:40] <jcoxon> cable found
[22:40] <jcoxon> just uploading
[22:42] <earthshine> RocketBoy: I had 25 in stock and were selling them at least £5 cheaper than anywhere else and it took like 6 months to get rid of them
[22:43] <RocketBoy> :-(
[22:43] <RocketBoy> jcoxon - how wide is the breakout? 1" ?
[22:46] <jcoxon> http://www.flickr.com/photos/jcoxon77/4905238823/
[22:48] <RocketBoy> cool - people have been busy in eagle
[22:50] <jcoxon> yeah getting there slowly
[22:51] <jcoxon> i reckon together they might sell better
[22:53] <RocketBoy> I'll see if I can get some FSA03s tomorrow
[22:55] <fsphil> sweet
[22:55] <fsphil> have you soldered up one yet?
[22:56] <jcoxon> fsphil, no waiting for a fsa03 to arrive
[22:56] <jcoxon> managed to lose the last one
[22:56] <fsphil> drat
[22:56] <jcoxon> its floating in the sea i think :-p
[22:57] <fsphil> oh, *that* one
[22:57] <jcoxon> but yeah fingers crossed this board works
[22:58] <jcoxon> happy to order some more - wouldn't be a challenge to cover the cost
[23:00] <jcoxon> just had a nice conversation on my local repeater
[23:00] <fsphil> yay!
[23:00] <jcoxon> much nicer then the london repeaters
[23:01] <Randomskk> nicer as in
[23:01] Nick change: SpeedEvil1 -> SpeedEvil
[23:02] <jcoxon> well people willing to talk, no one abusing it and didn't discuss my prostate or the traffic
[23:02] <fsphil> anyone using the linux version of eagle, or should I use the win32 version + wine?
[23:02] <Randomskk> linux eagle is wonderful
[23:02] <Randomskk> works perfectly
[23:03] <Randomskk> woudln't bother with the wine version at all
[23:03] <RocketBoy> london repeaters - they were bad in 1980 when I left london - I don't expect they have got better
[23:03] <Randomskk> installs right off and haven't had any issues since
[23:03] <RocketBoy> just installing eagal on da mac
[23:03] <fsphil> thanks Randomskk, going to give it a try soon. so expect some newbie questions ;-)
[23:03] <jcoxon> RocketBoy, eagle on mac isn't bad
[23:03] <fsphil> the repeaters here are fairly quiet - most conversations seem pretty civil
[23:04] <jcoxon> i was just really testing my rig out
[23:04] <Randomskk> the repeater here is a bit traffic and medical
[23:04] <Randomskk> I haven't really spoken on it
[23:04] <jcoxon> just stuck the antenna indoors seem to get 11 miles with 5w
[23:04] <Randomskk> in fact the only time I have actually spoken on the radio was via echolink and gb3py in cambridge to rjharrison
[23:04] Action: Randomskk has a full license
[23:05] <fsphil> quite possibly the only full licensee to not use a radio ;-)
[23:05] <Randomskk> I do use it... for receiving :P
