[00:08] <Randomskk> BOM is down to about £6/£7 if I don't go for the stm32
[00:08] <Randomskk> not including pcb but it's pretty small
[00:09] <Randomskk> much better
[00:09] <Randomskk> before was like, loads more
[00:09] <Randomskk> save another 10p by dropping to an atmega88 too
[00:10] <Randomskk> choices choices
[00:10] <Randomskk> this avr vs arm choice is tough
[00:10] <Randomskk> I guess if I can do it on an avr then there's no point to the stm32
[00:10] <Randomskk> but it would be way nicer. that timer is hot stuff
[00:10] <Randomskk> anyway sleep
[00:10] <SpeedEvil> what's this for?
[00:10] <SpeedEvil> night
[00:10] <Randomskk> SpeedEvil: quadcopter motor controller
[00:10] <SpeedEvil> ah
[00:10] <Randomskk> so, little bldcs
[00:10] <Randomskk> up to about 20A tops
[00:10] <SpeedEvil> quad ESC basically then?
[00:11] <Randomskk> well
[00:11] <Randomskk> single motor per esc
[00:11] <SpeedEvil> yeah
[00:11] <Randomskk> but yea, an esc for my quad
[00:11] <Randomskk> the stm32 has a timer peripheral designed for BLDC control really
[00:11] <Randomskk> handles all sorts of stuff for you
[00:11] <Randomskk> very nice
[00:11] <SpeedEvil> neat
[00:11] <Randomskk> and a lot of app note stuff about doing it
[00:11] <Randomskk> plus it has loads of 12bit ADC inputs
[00:11] <Randomskk> all of which can run freewheeling and interrupt when they exceed some given value
[00:12] <SpeedEvil> of course - with the speed - you could trivially bitbang it too
[00:12] <Randomskk> yea 72mhz gives you a lot more headroom
[00:12] <Randomskk> also allows for very fast comms with host
[00:12] <Randomskk> since spi
[00:12] <SpeedEvil> yes.
[00:12] <Randomskk> and you can start doing everything on interrupt and dma
[00:12] <Randomskk> which is also nice
[00:12] <Randomskk> dma in host messages, dma out response, takes almost no cpu time
[00:13] <Randomskk> you can rig is so the ADC monitoring the current or battery voltage will detect when they cross the too-much-current or too-low-voltage levels and automatically trigger the timer to emergency stop the motor
[00:13] <Randomskk> on the flip side though they don't ICSP over SPI so I'd have to add a serial header for programming
[00:13] <Randomskk> which is a bit pants
[00:13] <Randomskk> but not the end of the world really
[00:14] <Randomskk> would make for easier debugging
[00:14] <SpeedEvil> serial bootloader is nice though.
[00:14] <Randomskk> yea it is
[00:14] <SpeedEvil> Absopositively non-brickable.
[00:14] <Randomskk> if I just shove the serial tx/rx onto the spi header, I can again reprogram the thing from the host
[00:14] <Randomskk> so total firmware upgrades could go ota for flight computer and motor controllers
[00:15] <SpeedEvil> For when you want to reprogram in flight.
[00:15] <SpeedEvil> The ultimate OTA upgrade.
[00:15] <Randomskk> definitely
[00:15] <Randomskk> do it one motor controller at a time, see if the other three can compensate :P
[00:15] <Randomskk> I suspect not
[00:15] <Randomskk> two might be able to, but again probably not
[00:15] <SpeedEvil> Shuttle and Apollo 13 did it - it's got to be a good idea.
[00:16] <SpeedEvil> :)
[00:16] <SpeedEvil> oh
[00:16] <Randomskk> but certainly you could do an autonmous land, reprogram, take off
[00:16] <SpeedEvil> one board per controller
[00:16] <SpeedEvil> err
[00:16] <SpeedEvil> per motor
[00:16] <Randomskk> yea
[00:16] <SpeedEvil> I thought you were doing 3
[00:16] <SpeedEvil> 4
[00:16] <Randomskk> one flight computer, four ESCs (one per motor)
[00:16] <Randomskk> one motor per STM32
[00:16] <SpeedEvil> for which 7 quid looked light
[00:16] <Randomskk> it would be
[00:16] <Randomskk> but sadly not
[00:17] <Randomskk> not sure how the stm32 handles multiple motors but I think I'd rather stick to one per motor, certainly for now at least
[00:17] <SpeedEvil> What does homebrew give you over commercial ESCs?
[00:17] <Randomskk> probably sod all of significance
[00:17] <SpeedEvil> :)
[00:17] <Randomskk> well
[00:17] <SpeedEvil> Good learning though.
[00:17] <Randomskk> mainly commericals are designed for pwm input
[00:17] <SpeedEvil> And better fault reporting
[00:17] <Randomskk> you can hack them for i2c
[00:17] <Randomskk> but allow hacking them up, I don't like the idea
[00:17] <Randomskk> plus mainly I want to do it myself
[00:17] <Randomskk> and it is a fantastic learning experience
[00:18] <SpeedEvil> True
[00:18] <Randomskk> also yes, error and other diagnostics
[00:18] <Randomskk> means my laptop flight control can show all sorts of pretty stats
[00:18] Action: SpeedEvil sighs.
[00:18] <SpeedEvil> I wish I could get moving on my UAV.
[00:18] <Randomskk> same, the motor controller is in the critical path sadly :P
[00:19] <SpeedEvil> I have the block of foam for the fuselage.
[00:19] <Randomskk> stm32 is massively tempting
[00:19] <SpeedEvil> But little else concrete.
[00:19] <Randomskk> but like, £2 is a lot on the bom
[00:19] <Randomskk> I have a metal framework, motors, batteries, gyros, accels, magnos, gps, stm32s, lots of bits of motor controller kit, charger, nice thick silicone wire...
[00:20] <Randomskk> http://www.flickr.com/photos/randomskk/3946272514/
[00:20] <SpeedEvil> My design has all of the expensive bits - well - less the camera - in one 'egg'
[00:20] <SpeedEvil> Basically a carbon fibre egg, with all the bits in.
[00:20] <SpeedEvil> With a dense foam round that, and thin fibreglass on top.
[00:21] <Randomskk> sounds like it'd be quite nice. I haven't given much thought to casing yet
[00:21] <SpeedEvil> Designed to take a full power vertical dive into concrete.
[00:21] <Randomskk> blimey
[00:21] <Randomskk> tough stuff
[00:21] <SpeedEvil> http://www.mauve.plus.com/test.png
[00:22] <SpeedEvil> I have not got much further than the render of it flying over
[00:22] <Randomskk> that looks sweet. ducts?
[00:22] <SpeedEvil> No.
[00:22] <Randomskk> or is that just the very core?
[00:22] <SpeedEvil> One big fan, with vectored thrust.
[00:22] <Randomskk> ah, sweet
[00:22] <SpeedEvil> The prop is at the top, the bottom has the four independant vanes.
[00:23] <SpeedEvil> The structure is mostly foam.
[00:23] <SpeedEvil> With the blobs having batteries, guidance, camera, and more batteries.
[00:23] <Randomskk> nice
[00:23] <SpeedEvil> I also have a laser ranger designed - that I need to build and get on ebay.
[00:24] <SpeedEvil> CDRW lasers are nice and powerful, and nice tight filters are available.
[00:25] <Randomskk> I wish I had more time to work on this stuff
[00:25] <Randomskk> and less to work on, well, work
[00:25] <SpeedEvil> :)
[00:25] <Randomskk> still
[00:25] <Randomskk> finish work in a few weeks
[00:25] <Randomskk> then I still have a few weeks of actual holiday
[00:25] <Randomskk> huzzah
[00:25] <SpeedEvil> :)
[00:25] <Randomskk> maybe I'll get r5 motor controllers made up, that'd be nice
[00:26] <Randomskk> then try writing some firmware in the first term of uni. or work on the weather station. or this hab launch.
[00:26] <Randomskk> projects projects projects
[00:26] <SpeedEvil> Currently having health problems - I have about a couple of hours a day functional, and that gets eaten up witrh boring stuff.
[00:26] <Randomskk> D: sucks
[00:26] <SpeedEvil> At lreast projects are moving forward.
[00:26] <SpeedEvil> First actual electronics consulting cheque.
[00:26] <SpeedEvil> Well.
[00:26] <SpeedEvil> Paypal.
[00:26] <SpeedEvil> Which helped with tesco.
[00:26] <Randomskk> close enough
[00:27] <Randomskk> what were you doing (can you say?)
[00:27] <SpeedEvil> Basically designing someone a power supply.
[00:27] <SpeedEvil> undervoltage lockouts, ADC reporting, ...
[00:27] <Randomskk> cool

[10:10] <timbobel> who knows php a bit
[10:11] <timbobel> randomssk you here
[10:16] <timbobel> or javascript??
[10:16] <timbobel> i need PHP to poll the contents of a textfile ever several seconds
[10:18] <fsphil> what are you trying to do?
[10:28] <timbobel> i have a textfile
[10:29] <timbobel> in that text file, every once in a while the info changes, its like 1 sentence
[10:29] <timbobel> it should poll that
[10:29] <timbobel> and put it in anothe text file
[10:30] <fsphil> can you not append the extra info to the text file?
[10:30] <timbobel> go here: http://94.208.64.238/poller.php
[10:30] <timbobel> so i do..
[10:30] <timbobel> and that works (i have ZERO php knowledge)
[10:31] <timbobel> but i want it to do that automatically; saying; if there is new info (other than the last) than it should put it into the log.txt where everything is appended
[10:32] <fsphil> where is the info coming from?
[10:32] <timbobel> ftp server
[10:32] <fsphil> ah
[10:32] <timbobel> my cellphone puts a textfile on there
[10:32] <timbobel> via GPRS
[10:33] <timbobel> and no, no other ways work
[10:33] <fsphil> hehe, was going to ask if you could use http
[10:33] <timbobel> yeah
[10:33] <timbobel> but not execute php scrips apparentelly
[10:33] <timbobel> otherwise id be done
[10:37] <fsphil> it would be ideal, have the phone push the data straight to your php script
[10:37] <fsphil> is there an error when you try? or it just doesn't work?
[10:43] <timbobel> doesnt work
[10:44] <timbobel> so a PHP refresher, anyone?
[10:46] <fsphil> I think you'd be better off trying to get the http working from the phone. you're not actually upload a file remember, just querying a url

[10:58] <timbobel> what? it is working already with the ftp stuff, but i want it to refreshhhh!!!!!
[10:58] <timbobel> now every time i visit that site it polls the info; reads the textfile and logs to another. but i want that to work for itself

[11:13] <fsphil> Try putting this at the beginning of your script: header("Refresh: 5; url=http://94.208.64.238/poller.php");
[11:14] <fsphil> you'll need a browser opened and on that page for it to work though
[11:16] <cuddykid> Hi all, just got back from holiday so its been a while since I've been on here! Just to let everyone know I'm going to try and launch my 1st balloon very soon.. just received CAA clearance for 23-30th aug so now a rush to get everything prepared in time!
[11:17] <fsphil> What I mean for the http thing is that, your phone opens the url... http://myserver/poller.php?data=blablabla -- the php script can read the data and append it to your file automatically without any refresh or ftp server
[11:17] <fsphil> wb cuddykid
[11:17] <fsphil> eep, you really don't have long to get ready :)
[11:18] <timbobel> ah i read this too late. i already have it fixed!
[11:18] <cuddykid> yes, i thought that! Payload is mainly ready to go, its just I need the balloon and helium now!
[11:19] <cuddykid> Is Steve from random solutions in this chat room? As i'll be getting the balloon from him I think
[11:24] <fsphil> not atm, his nick is RocketBoy
[11:26] <cuddykid> ok, thanks fsphil. Where do you guys usually get the helium from? I've emailed Boc but they haven't replied yet
[11:33] <russss> ring BOC, they're useless at email
[11:33] <russss> or find a trade counter
[11:34] <fsphil> my local trader suggested I find someone who already has an account with boc, as they likely have a discount
[11:40] <cuddykid> ok, might ring them later! thanks
[11:42] <russss> although, if you ring them, they will send you an incomprehensible form to fill in. You're probably better going to a trade counter
[11:42] <fsphil> cuddykid, how long did it take for the caa to process your request?
[11:44] <cuddykid> lol ok russss ! .. fsphil, took them ages! Around a month or possibly a little longer, I phoned the guy a week after I sent it and it took him over a day to find the application, he said they were very busy
[11:50] <fsphil> I'm at the two month mark now :/
[11:52] <cuddykid> ooft, I'm sure it would be much quicker if they made it all online, instead of having to fill out those forms where half the fields make no sense!
[11:53] <fsphil> yea - would save them time too
[11:54] <fsphil> there is the short email format mentioned here -> http://www.ukra.org.uk/notam
[11:58] <cuddykid> I tried that to begin with, but they refused to do it! They wanted me to mail them it! argh
[11:59] <fsphil> post?
[12:00] <cuddykid> yes
[12:01] <cuddykid> with an os map section attached!
[12:02] <fsphil> ahh, I emailed them with a scan of the map
[12:06] <cuddykid> hopefully that'll be alright :)
[12:09] <fsphil> dunno, I emailed them a few weeks ago to check but didn't get a reply. I'll probably have to phone them

[18:45] <Upu> timbobel nice one :) P.s Clean the coffee stain off your desk :)
[18:45] <timbobel> i have a girlfriend for that
[18:46] <timbobel> Though she refuses.
[18:46] <Upu> "the googly thing" lol
[18:46] <timbobel> where do i say that
[18:46] <timbobel> thanks btw upu
[18:46] <timbobel> i used your idea, works great
[18:46] <timbobel> took me ages to figure out that with comparing strings you have to use "===" (x3!)
[18:47] <Upu> no problems
[18:47] <Upu> my coding ability could be politely called "limited" so there is probably a better way of doing it
[18:48] <JackNorris> Upu loves Java
[18:48] <Upu> its PHP
[18:48] <Upu> And Matt
[18:49] <JackNorris> but you wish he had used Java, right?
[18:49] <Upu> you need to make something that runs on the iPhone that updates the tracker
[18:49] <Upu> no java is evil
[18:49] <Upu> for the chase car
[18:49] <Upu> seems daft to have a GPS in the phone and not use it
[18:49] <JackNorris> Err, shouldn't really be an issue
[18:50] <Upu> iphone programming is really out of my league
[18:50] <JackNorris> Serial access is working good now, i'm just writing a decent asynchronous serial class now
[18:50] <Upu> ask someone here but all you do is post your location to a website
[18:50] <Upu> anyway I need to cook back later on
[18:50] <timbobel> yeah iphone could be nice too
[18:50] <timbobel> you're forgetting that this setup is cheaper than any commerically available tracker
[18:51] <JackNorris> Isn't the only important bit the balloon location?
[18:51] <timbobel> i am not even sure this setup is allowed in terms of safety or personal stuff
[18:51] <timbobel> surely i am going to track my girlfriend everywhere she goes from now on
[18:51] <JackNorris> Or you mean have the iPhone send where the balloon is?

[19:03] <jonsowman> hi Upu
[19:03] <Upu> when a balloon is being tracked
[19:03] <jonsowman> :)
[19:03] <Upu> the position of the chase car(s) are also on the map
[19:04] <Upu> it seems silly to have an iPhone in the pocket with internet and gps and not use that for the chase car
[19:05] <Upu> guys what do we need to do / send to a server to update the position of the chase car ?
[19:05] <Upu> I've seen someone post it and it looked quite simple
[19:05] <natrium42> just a HTT POST or GET
[19:05] <natrium42> *HTTP
[19:05] <Upu> URL / format ?

[19:06] <natrium42> would be cool to have an iphone app
[19:06] <Upu> JackNorris will make one, I'll put money there will be one in about an hour
[19:07] <natrium42> cool :)
[19:08] <timbobel> wow seriously?
[19:08] <Upu> right afk, Matt if you don't write one in an hour you're fired kk ? :)

[20:10] <Randomskk> right, back
[20:11] <Upu> wb
[20:13] <Randomskk> yay weekend
[20:22] <Upu> question what is the format of GPS that is ddmm.mmmm dddmm.mmmm called ?
[20:22] <Upu> does it have a name ?
[20:24] <jonsowman> degrees decimal minutes is what I call it
[20:24] <jonsowman> i'm not entirely sure that's correct
[20:25] <natrium42> <JackNorris> and what happens if you don't send the tracker a heading? <-- that's fine
[20:25] <Upu> I'm trying to work out how to convert N53°45'9" W1°49'5" to it
[20:25] <SpeedEvil> Upu: simple
[20:25] <Upu> Yeah we worked that out natrium42 :) http://ava.upuaut.net/tracker/
[20:25] <SpeedEvil> Upu: 45+(9/60)
[20:25] <natrium42> Upu, mold
[20:25] <natrium42> do you want the "new" source?
[20:26] <Upu> sure
[20:26] <SpeedEvil> Upu: So 53.4515
[20:26] <natrium42> don't you have access to the habhub server?
[20:26] <natrium42> just grab it from there
[20:26] <Upu> yes I do
[20:26] <Upu> ok where is it ?
[20:26] <Upu> anywhere obvious ?
[20:26] <natrium42> /var/www/default/tracker
[20:26] <natrium42> and the database is tracker
[20:26] <Upu> so 5345.15 SpeedEvil ?
[20:26] <Upu> k thx
[20:27] <Randomskk> btw you can just send it in that format iirc, it'l take anything
[20:27] <Randomskk> like
[20:27] <natrium42> Randomskk?
[20:27] <Randomskk> http://gist.github.com/479637 does it straight from nmea
[20:27] <Randomskk> what does iphone gps give you?
[20:28] <Upu> N53°45'9" W1°49'5"
[20:28] <Randomskk> ew. how does it send that, technically?
[20:28] <Upu> that right JackNorris ?
[20:28] <Randomskk> presumably not a string with ° and shit
[20:28] <Upu> not sure Jack is doing doing the code
[20:29] <natrium42> could the iphone app have text boxes for server url and password? :)
[20:29] <Upu> of course
[20:30] <natrium42> also maybe a spinner for frequency
[20:30] <natrium42> cool
[20:30] <Upu> he's a registered developer
[20:30] Action: natrium42 is too
[20:30] <Upu> so you probably won't even need a jail broken iphone
[20:30] <natrium42> but my objective C is rusty :S
[20:30] <Upu> I pride myself on not even knowing what objective C is
[20:31] <natrium42> haha
[20:32] <JackNorris> either or really
[20:32] <natrium42> bbl tea
[20:32] <natrium42> app better be finished when i return!
[20:32] <natrium42> j/k

[20:35] <JackNorris> lat/long on the iphone is basically just a float
[20:37] <Randomskk> decimal degrees?
[20:37] <Randomskk> dd.ddddd?
[20:41] <JackNorris> Yeah
[20:41] <Randomskk> I believe that will just upload directly
[20:43] <Upu> http://ava.upuaut.net/tracker/ ok think that's the new one
[20:43] <Upu> I have a car logo now not sure how I managed that
[20:43] <Randomskk> chase-* as the name
[20:43] <Upu> oh I called it AvaChase

[22:00] <jcoxon> weird
[22:01] <Randomskk> ugh. still can't decide on stm32 vs avr for the motor controller
[22:01] <Randomskk> stm32 isn't that expensive and is really nice, but if I'm going for a super cheap motor controller it's entirely wrong
[22:01] <Randomskk> and all the other parts are super cheap: cheapest mosfets, cheapest transistors, cheapest amp, etc
[22:01] <Randomskk> if I was using an stm32 it seems like I should be using decently specced everything
[22:01] <Randomskk> otoh then I may as well just be doing open-bldc

[23:58] <Laurenceb> in fact if i got the ftdi/si4432 usb stick designed as well that would fit

[23:58] <Laurenceb> is one way to look at it... but they may see it as loosing money
