[09:13] <m1x10> hey fsphil
[09:13] <m1x10> Im about to live home and go searcch for a soldering station.
[09:13] <m1x10> leave*
[09:13] <m1x10> I found this on greek market --> ZD937
[09:13] <m1x10> Do u know if its good for me?
[09:13] <m1x10> a starter :p
[09:14] <fsphil> looks very technical :)
[09:15] <fsphil> this is what I have: http://www.maplin.co.uk/Module.aspx?ModuleNo=35016
[09:15] <m1x10> what do u mean?
[09:15] <m1x10> it costs 55euros. I need it just to solder headers and stuff like that.
[09:15] <m1x10> lol, yours look less complex
[09:17] <m1x10> so do u think its ok ?
[09:18] <fsphil> should do the job nicely
[09:20] <fsphil> yay, bbc forecast >0 temperature on sunday
[09:21] <m1x10> I should trust you and order it from athens.

[09:25] <m1x10> why would the iron be of a question?
[09:27] <m1x10> its this: http://www.emimikos.gr/shop/popup_image.php?type=D&id=20522&title=SDL-937%20%D3%F4%E1%E8%EC%FC%F2%20%EA%FC%EB%EB%E7%F3%E7%F2%20ZD-937&area=C
[09:30] <fsphil> it isn't, just that you can't trust my opinion on it :)
[09:31] Action: m1x10 cant understand fsphil's phil-osofic words
[09:34] <fsphil> It *looks* good, but I don't know how well it works
[09:35] <fsphil> but any iron with a stand and a fine tip should do the job
[09:39] <m1x10> thats a bit more human answer :):)
[09:41] <fsphil> still early here, haven't woken up yet ;)
[09:41] <m1x10> here is 12

[12:23] <m1x10> Ok, I now have a solder station
[12:39] <Laurence_> http://ardrone.parrot.com/parrot-ar-drone/uk/
[12:40] <jonsowman> i want one
[12:42] <Laurence_> its _very_ lame
[12:42] <Laurence_> im just wondering how hackable it is
[12:43] <Laurence_> wifi is utterly unsuitable
[12:43] <fsphil> ah, that's the thing from top gear?
[12:44] <jonsowman> indeed
[12:44] <fsphil> I was impressed by how steady it seemed
[12:44] <Laurence_> wonder if you could modify it to use something sensible
[12:45] <Laurence_> http://www.ifixit.com/Teardown/Parrot-AR-Drone-Teardown/3984/1
[12:46] <Laurence_> wow they rolled custom silicon for it
[12:46] <Laurence_> crazyness
[12:47] <Laurence_> http://guide-images.ifixit.net/igi/HBjGCPkpNjxiXbor.medium <- now that looks like a useful module
[12:47] <Laurence_> if someone can hack the protocol
[12:48] <Laurence_> looks like its using optical flow + invensense gyros
[12:48] <Laurence_> interesting
[12:50] <Laurence_> the besc modules are really nice, but probably not worth the money for hacking, as its really limited what you can do with optical flow based attitude estimation
[12:50] <Laurence_> also custom arm9 so no chance of reflashing the firmware

[14:00] <SpeedEvil> well - yes
[14:00] <SpeedEvil> But also neat
[14:01] <Laurence_> guess yu get a 1100mh cell and some "propulsion modules" for that

[14:02] <Lunar_Lander> hello
[14:02] <Laurence_> but the main board is pretty useless as its all custom silicon/atheros stuff
[14:02] <Lunar_Lander> jonsowman is the Predictor Online?
[14:02] <Lunar_Lander> it only goes as far as "Getting Wind Data"
[14:04] <Laurence_> but yeah the gyro+optical flow idea is interesting
[14:04] <Laurence_> thing is you really need rotation rate output from the optical flow as well - mouse sensors dont give that
[14:05] <Laurence_> two mouse sensors might help
[14:10] junderwood (~John@adsl.jcu.me.uk) joined #highaltitude.
[14:11] <SpeedEvil> I really doubt it's custom
[14:11] <SpeedEvil> it'll be a POP with ROM+RAM
[14:11] <SpeedEvil> and they'll have assembled that and marked it
[14:11] <SpeedEvil> some smartphone SoC
[14:13] <SpeedEvil> I'd not even be surprised to see linux in there
[14:13] <SpeedEvil> https://sites.google.com/site/repurposelinux/df3120
[14:25] <fsphil> it does run linux, they've got a gpl page on their site

[14:26] <Lunar_Lander> could you please do me a favour and tell jonsowman that the predictor does't work?
[14:26] <Lunar_Lander> that would be great as I have to leave now
[14:27] <fsphil> he'll see your message when he gets back
[14:28] <fsphil> the problem is likely with noaa though

[15:05] <m1x10> I think that in order to reduce some voltage I can use a zener diode
[15:06] <SpeedEvil> zener diode for waht?
[15:06] <m1x10> so a raw 6V will become 5.xV using a diode
[15:06] <m1x10> and that will be safe for use with the humidity sensor which works up to 5.8V
[15:07] <m1x10> erase the zener.
[15:07] <m1x10> just a diode.
[15:07] <SpeedEvil> yeah
[15:07] <m1x10> a diode's voltage drop will help me
[15:07] <m1x10> plus it will be used as a protection diode
[15:07] <m1x10> righT?
[15:07] <SpeedEvil> possibly.
[15:08] <m1x10> I start to understand at my own some tronics knowledge :)
[15:08] <SpeedEvil> I don't know the circuit - a normal diode in series will drop the supplly voltage from 0.4-1V or so depending on current
[15:10] <m1x10> but i will have those 6v only when I work with the batteries
[15:10] <m1x10> I also have the usb2ttl 3v3 power source and a wall adapter barrel jack at 7-12v
[15:11] <SpeedEvil> 4 batteries in series can hit 1.65V*4 fresh from the shop
[15:11] <SpeedEvil> alkaline
[15:11] <m1x10> yes
[15:12] <m1x10> my pcb supports 3 power sources
[15:12] <m1x10> 1. 4 bats in series
[15:12] <m1x10> 2. usb2ttl 3v3
[15:12] <m1x10> 3. wall adapter
[15:13] <m1x10> when i use the 1,3 i use a 3v3 regulator
[15:13] <m1x10> LD33v
[15:14] <m1x10> Now i should start soldering the usbtinyISP
[15:14] <m1x10> I got all the tools
[15:14] <m1x10> but first i should watch some youtube vids
[15:15] <m1x10> http://www.ladyada.net/make/usbtinyisp/solder.html
[15:16] <fsphil> maybe best to practice on something first
[15:18] <eroomde> spotify should have musical context sensitive adverts

[15:29] <fsphil> what sort of solder are you using? lead-free?
[15:35] <m1x10> what means lead-free?
[15:36] <eroomde> 95%...
[15:36] <m1x10> haha
[15:37] <SpeedEvil> Lead free means it has no lead
[15:37] <eroomde> the metallic component of solder used to be lead. lead is a heavy metal and pollutant so there is no 'lead free' which the consumer electronics industry is switching to (or has switched already) but it's not nearly as nice to work with
[15:37] <m1x10> can u show me a pic with a lead-free and with a non lead-free
[15:38] <eroomde> and significantly harder to re-work
[15:38] <SpeedEvil> They look the same
[15:38] <eroomde> they look the same
[15:38] <m1x10> :p
[15:38] <eroomde> but the space industry still use lead
[15:39] <m1x10> eee..we belong to space industry?
[15:39] <eroomde> lead-free's outgassing (volatile components subliming in the zero pressure) properties have not been explored enough for space applications to risk switching
[15:39] <eroomde> and outgassing is bad as it, say, coats your optica components or whatever
[15:39] <m1x10> i buy my solder from sparkfun
[15:40] <m1x10> and other related shops
[15:40] <m1x10> so i think its lead-free
[15:40] <fsphil> I've yet to try lead-free - but I've heard plenty of opinions on it
[15:40] <eroomde> it will tell you what it is on their site
[15:41] <eroomde> you'll see a logo which will be the letters 'RoHS' on european imports
[15:41] <eroomde> that means they'll be lead free, among other things
[15:41] <eroomde> that just means they conform t the restriction of hazardous substances directive

[17:32] <jcoxon> evening all
[17:32] <SpeedEvil> evening!
[17:33] <jcoxon> ping eroomde
[17:33] <SpeedEvil> he last said something a couple of hours ago
[17:35] <jcoxon> oh
[17:35] <jcoxon> oh well, will text instead
[17:37] <jcoxon> next: ping russss
[17:37] <russss> hello
[17:37] <jcoxon> autonomous blimp
[17:37] <jcoxon> wants some help?
[17:38] <russss> maybe
[17:38] <russss> we have some plans, I need to write them down later
[17:38] <russss> perhaps next week
[17:38] <jcoxon> fair enough
[17:38] <jcoxon> was thinking a rfbee would be a good basis
[17:38] <jcoxon> arduino + 868mhz 10mW tx on xbee footprint
[17:39] <russss> I had a fucking gumstix for it, but I believe someone has stolen it from the hackspace.
[17:39] <jcoxon> eek
[17:40] <russss> or maybe just hidden it very well
[17:40] <jcoxon> they are mini
[17:41] <Laurence_> blimp souds cool
[17:41] <Laurence_> personally id want to try semi rigid
[17:41] <Laurence_> with two props - one on either side
[17:42] <Laurence_> but im probably going ott
[17:42] <jcoxon> Laurence_, you never go ott :-p
[17:42] <russss> I'm going to make a lightweight nylon outer envelope
[17:42] <russss> to make it a little more durable
[17:42] <Laurence_> ah - the nylon film?
[17:43] <russss> fabric
[17:43] <russss> you can get it pretty light
[17:43] <Laurence_> oh i see
[17:43] <Laurence_> you can get mylar wannabe nylon film
[17:43] <SpeedEvil> I suggest a hydrogen filled envelope, with a covering with aluminium dust, and nitrate dope.
[17:43] <russss> basically B-grade parachute material
[17:44] <Laurence_> yeah i used it on the rogallo
[17:45] <Laurence_> if you have a servo mounted motor on each side and a basic frame - ie semi rigid

[17:45] <Laurence_> and no need for and other controls
[17:46] <russss> yeah
[17:46] <russss> that is basically the plan
[17:46] <Laurence_> nice
[17:46] <Laurence_> make it slightly heavier than air as well
[17:46] <Laurence_> russss: my autppilot board would work well for that
[17:47] <Laurence_> - 9DOF, stm32, 4xservo io
[17:47] <SpeedEvil> It would be awesome.
[17:48] <Laurence_> havent had time to populate any board, but you're welcome to have some as ive got spares
[17:48] <Laurence_> only issue is it has a falcom fsa03 footprint, im going to swap that for ublox6 on v2, but there is a 0.1'' header for the gps

[18:19] <jonsowman> hi jcoxon
[18:19] <jonsowman> " * if payload has a lock variable only uploads when gps has a lock"
[18:19] <jonsowman> any further info on this?
[18:20] <jcoxon> yeah, so if they tx a field with 0 or 1 and the xml describes a lock variable it'll only up load when it gets a 1
[18:20] <jcoxon> something i added for atlas as a test
[18:21] <jonsowman> right, ok
[18:21] <jonsowman> wondering whether to implement it on Apex
[18:21] <jonsowman> Matt_soton: ^^
[18:21] <SpeedEvil> Hmm.
[18:21] <SpeedEvil> temperature is useful even in the absence of lock
[18:21] <jcoxon> but it only applies if the xml describes a lock field - therefore won't matter if you don't have it
[18:21] <SpeedEvil> to indicate burst
[18:22] <jonsowman> ok
[18:22] <jonsowman> SpeedEvil: yeah I think I'd prefer dl-fldigi to upload all sentences
[18:22] <jcoxon> SpeedEvil, indeed - also makes it easy to visually look at dl-fldigi before hand (as instead of going green the bar goes yellow)
[18:22] <Matt_soton> well when theres no lock thers no GPS field in the string
[18:22] <jcoxon> as i said its optional
[18:23] <jcoxon> some flight computers report the last known lock
[18:23] <jonsowman> Matt_soton: Apex is uploading an empty field for `sats`
[18:23] <jcoxon> sorry the last know gps position
[18:26] <jonsowman> Matt_soton: ideas?
[18:26] <Matt_soton> i had been fiddling to remove hte need for the RTC RAM, but it doesnt speed it up more so ill move back and it should just work again

[22:20] <m1x10> the programmer is powering the mcu from the vcc?

[22:23] <fsphil> well, that was brief -- 22:23
[22:23] <m1x10> but now that i have coneccted the vcc of the header to get mcu isnt that bad?
[22:24] <fsphil> vcc carries the board voltage to the programmer, so it can use that to program the chip

[22:46] <m1x10> right
[22:47] <m1x10> "The fuses define things like the clock speed, crystal type, whether JTAG is enabled, what the brownout (minimum voltage) level is, etc."
