[08:42] <adamgreig> So, ATmega328PB
[08:43] <adamgreig> Double up on spi, i2c, uart
[08:43] <Vaizki> Moar timers also
[08:44] <Vaizki> a friend said the debugwire single pin debugger stuff is also very good on it
[08:46] <Vaizki> I need to order a stm32f303 nucleo.. has good ADCs, integrated opamps and PGA .. :O
[08:47] <fsphil> go for the f4
[08:49] <Vaizki> does it have a PGA?
[08:49] <fsphil> there are too many. don't know the difference between most of them
[08:50] <fsphil> apparently not
[08:50] <fsphil> that's an interesting thing
[08:51] <Vaizki> yes especially for thermocouples
[08:52] <AndyEsser> adamgreig: nice
[08:52] <fsphil> you can finally have that debug serial port *and* gps
[08:53] <AndyEsser> fsphil: me?
[08:53] <fsphil> yeah
[08:53] <AndyEsser> I already have that
[08:53] <AndyEsser> the UART on my 328's are purely serial cli
[08:53] <AndyEsser> GPS is I2C
[08:53] <AndyEsser> and RTTY is bit banged
[08:53] <fsphil> ah yes you went i2c
[08:53] <eroomde> The adc resolution drops off with G if using the PGA iirc
[08:53] <eroomde> which is pretty bollocks
[08:53] <R34lB0rg> there is a gps for i2c?
[08:54] <AndyEsser> Ublox MAX M8C is what I use
[08:54] <eroomde> R34lB0rg: read the max8 datasheet please
[08:54] <fsphil> would the PGA be useful in making a single chip LF receiver
[08:54] <R34lB0rg> eroomde, believe it or not, that was what I was just going to do
[08:55] <fsphil> would still need a low pass filter on the input likely
[08:55] Action: AndyEsser googles PGA and then realises he's a muppet
[08:55] <eroomde> i'll choose to not believe it
[08:56] <AndyEsser> is a PGA just an FPGA without the F
[08:56] <AndyEsser> ?*
[08:56] <eroomde> no
[08:56] <eroomde> well yes
[08:56] <eroomde> but not in this context
[08:56] <fsphil> programmable gain amplifier
[08:56] <eroomde> the clue, watson, is Vaizki's use of the term in the context of thermocouples
[08:56] <eroomde> which have very low (mV) outputs
[08:56] <fsphil> (spoilers)
[08:57] <fsphil> new to me too
[08:57] <AndyEsser> eroomde / fsphil - ta muchly
[08:57] <eroomde> thus need a bit of amplification (and some other stuff) before being hooked up to an adc. the atmega has the option of hooking some adc inputs up through an internal programmage gain amplifier
[08:57] <eroomde> that does something like 1x, 20x, 200x gains
[08:58] <eroomde> probably not those exactly but something like that
[08:58] <AndyEsser> Ah ok - gotcha - thanks
[08:58] <eroomde> but as i said i think you lose adc resolution as you up the gain which sucks
[08:58] <Vaizki> hmm yes that sucks
[08:58] <Vaizki> so its oversampling?
[08:58] <fsphil> higher noise floor?
[08:59] <eroomde> unless super power sensitive, i'd always just do a decent instrumentation amplifier front end with common mode filtering and other things
[08:59] <eroomde> for this kind of thing
[08:59] <Vaizki> well not oversampling... averagi g or something
[08:59] <Vaizki> eroomde, yes I am goong to build a wireless BBQ controller/monitor with it

[09:00] <Vaizki> thermocouple needed only to detect lid opening really, thermistors are too slow
[09:00] <eroomde> ah fine
[09:00] <eroomde> so 6 bits is probably plenty
[09:01] <Vaizki> yes I dont need the precision but the speed
[09:05] <Vaizki> You could probably do a GFSK receiver at least with the PGA and ADC in the stm32f3?
[09:07] <Vaizki> and I got the impression there is low pass filtering capability built in also to some extent
[09:08] <fsphil> possibly
[09:08] <fsphil> can the PGA be used on two inputs?
[09:10] <fsphil> STs website is kinda annoying

[10:58] <craag> Just connected an ftdi RX line to GPS tx (and ground of course), and then run ucenter
[10:58] <Vaizki> may I suggest hooking up a serial cable :)

[11:27] <UpuWork> oh I read the article on that was interesting
[11:27] <craag> Not sure about the slanty LEDs
[11:28] <craag> Seems like it'd be more difficult to read
[11:28] <eroomde> there exist those fancy silk printing panel places online
[11:28] <craag> Does look nice at a distance though :)

[11:28] <eroomde> you just put the picture ontop of a dxf and send it off
[11:28] <fsphil> nicam was a great development for its time
[11:28] <UpuWork> oh yes that article craag
[11:28] <eroomde> i like the traco isolated dc/dc converter bricks they use
[11:28] <eroomde> as you know, i am a fan
[11:29] <eroomde> https://twitter.com/eroomde/status/545285116554403840
[11:29] <fsphil> yeah I recognised those from pictures you'd posted before
[11:30] <mattbrejza> those slanty leds look like theyre connected via terminal blcoks :/
[11:30] <fsphil> they are
[11:30] <fsphil> http://www.bbc.co.uk/rd/sites/50335ff370b5c262af000004/assets/569e5e8f06d63e7cbc017a6e/DSC0067_nicam_internal.jpg
[11:31] <fsphil> power brick velcro'd to the front too :)
[11:31] <fsphil> braided cable bundles look great
[11:31] <mattbrejza> fpga dev board rahter than putting it on the pcb
[11:32] <eroomde> that's a zync
[11:32] <eroomde> i'm pretty sure
[11:32] <mattbrejza> thats the fpga + arm A core?
[11:32] <eroomde> yes
[11:32] <fsphil> the link goes to http://www.xilinx.com/products/silicon-devices/soc/zynq-7000.html
[11:32] <eroomde> made by digilent as it has those p-pod or whatever they call it connectors
[11:33] <mfa298> that article is a great demo of what happens when techies do their job well.
[11:33] <eroomde> the ZedBoard
[11:33] <nick_> I looked at the Zynq last summer, since I think it can do some cool things for me.
[11:33] <fsphil> mfa298: wonder how many people complained after they found out :)
[11:33] <mattbrejza> oh lol it says fpga + arm right under the photo i was looking it
[11:33] <eroomde> http://store.digilentinc.com/zedboard-zynq-7000-arm-fpga-soc-development-board/
[11:33] <nick_> Unfortunately they are crazy expensive.
[11:33] <eroomde> they have used the high speed connector to break it out
[11:33] <eroomde> which is smart
[11:33] <mattbrejza> $500 is pretty cheap
[11:34] <eroomde> the digilent board i have also has such a connector
[11:34] Action: mattbrejza is using a $3k fpga board box as a footrest
[11:34] <eroomde> not that dense but still suitable for as fast as the fpga will do
[11:34] <nick_> The dev board is a loss leader
[11:34] <nick_> Or at least the one with the type of FPGA we wanted was.
[11:34] <nick_> (perhaps given to people for free)
[11:35] <eroomde> i'd give you a free dev board if i thought you might put 1024 of them into ADC cards for a particle detector
[11:35] <nick_> If we want to actually buy the chips it's still considerably cheaper for use to buy an FPGA + computer.
[11:36] <nick_> And send all our data over the network, which is what we do.
[11:36] <Hilts> ah latency, got to love it. scrolling up and,... read comments. assemble first, read instructions later. Yep I'll read the comments. ;) flight mode disabled.
[11:37] <nick_> Which is a shame, since there's some simple logic we'd like to do that could dramatically reduce the data but is much simpler to implment in a CPU than in an FPGA.
[11:38] <craag> Hilts: I only ever flew it on foil picos, so pedestrian mode was used. The flight mode code is in there, just commented out (and not sure it tests :/ )
[11:40] <nick_> One of our problems is that we don't buy 1k of chips, almost for anything.
[11:40] <SpacenearUS> New vehicle on the map: 03Car_chase - 12http://tracker.habhub.org/#!qm=All&q=Car_chase
[11:40] <nick_> It's fairly rare for our projects to buy even 100 FPGAs, really.
[11:40] <Hilts> right now I'm just a pedestrian anyway. I tweaked it to use softserial for debugging.
[11:42] <craag> Hilts: please be aware that softserial might screw with the crude rtty timing.
[11:42] <Hilts> understood. So far so good.
[11:43] <Hilts> by that I mean just getting rtty data on alt and location was reward in itself
[11:47] <craag> :)

[12:11] <adamgreig> talking of dataloggers eroomde
[12:11] <adamgreig> do you worry about running cables carrying +v excitation to strain gauges that might then break and short and cause a really sad time for other electronics?
[12:11] <adamgreig> trying to work out if the solution here is also the traco isolating things
[12:12] <eroomde> no because all my cards are galvanically isolated from each other
[12:12] <eroomde> so there are no earth or otherwise current loops
[12:13] <eroomde> and i have io protection everywhere
[12:13] <eroomde> e.g. all my 4-20mA circuits have a 40mA polyfuse both on the way out and the way back
[12:13] <eroomde> 50mA sorry
[12:14] Guest50077 (~xfce@cpe-85-10-26-137.dynamic.amis.net) left irc: Ping timeout: 256 seconds
[12:14] <eroomde> and there are global fuses for things like the prevision 10V excitation rail for all the bridge sensors
[12:14] <eroomde> precision*
[12:15] <adamgreig> hmm
[12:15] <adamgreig> are the fuses fast enough?
[12:17] <eroomde> yes
[12:17] <adamgreig> stupid question really
[12:17] <eroomde> that's to protect the 10V supply
[12:17] <eroomde> it's a polyfuse
[12:17] <adamgreig> maybe that will do in this case
[12:17] <eroomde> the sensors are all protected per-sensor with the io as i described
[12:17] <eroomde> but the gloabl polyfuse for a rail that supplies say all 8 channels of a bridge card is to protect to precision 10V supply
[12:18] Laurenceb_ (~Laurence@host86-180-138-212.range86-180.btcentralplus.com) left irc: Ping timeout: 240 seconds
[12:18] <mfa298> when I looked at poly fuses I found most had plenty of good information in the datasheet for how quickly they would stop current based on over voltage / current situations
[12:18] <eroomde> which is derived from the 2v5 voltage reference, multiplied by 4 through a precise op-amp, then fed to a mosfet on the 15V rail
[12:18] <adamgreig> my concern is protecting the rest of an avionics stack from having one of the supply lines being used for remote bridge excitation being shorted
[12:18] <eroomde> so basically just a precise DIY linear reg
[12:19] <eroomde> if it's a constant current excitation then i'd just go with the per-sensor polyfuses
[12:19] <adamgreig> it's a bridge so a voltage excitation
[12:19] <adamgreig> ?
[12:19] <mattbrejza> you can always make a current limit with a couple transistors anyway
[12:20] <eroomde> some bridges are constant current
[12:20] <eroomde> especially strain-type bridges
[12:20] <eroomde> just in the spec of how to use them
[12:20] <adamgreig> fair enough
[12:20] <eroomde> you still measure a differential voltage, it's just the excitation that is a user choice
[12:21] <adamgreig> right
[12:21] <eroomde> so the resitance of polyfuses can vary which is why i shy away from saying use them for precision voltage excitation
[12:21] <eroomde> *unless* you have excitation sensing
[12:21] <eroomde> in which case, knock yourself out
[12:21] <eroomde> we do have excitation sensing on the more precise bridge sensors
[12:21] <eroomde> don't bother on the housekeeping sensors
[12:23] <adamgreig> ok
[12:23] <adamgreig> can probably do at least sensing after the polyfuse
[12:24] <eroomde> yes that's the point
[12:24] <eroomde> polyfuse is on the pcb end
[12:24] <adamgreig> I mean on the PCB after polyfuse, but not at the bridge
[12:24] <eroomde> sense leads measure right at the guage ports
[12:24] <adamgreig> sure
[12:24] <adamgreig> wouldn't you ideally measure at the bridge itself?
[12:24] <eroomde> yes
[12:24] <eroomde> that's what i mean by guage ports
[12:24] <eroomde> i think you mentioned it was a straing guage bridge earlier
[12:24] <adamgreig> indeed
[12:24] <eroomde> might have made that up, sorry if so
[12:25] <adamgreig> right, but failing that, measuring at the PCB connector to the bridge beats not measuring or measuring before the polyfuse
[12:25] <eroomde> sure ish
[12:25] <eroomde> if all the leads are the same length and roughly isothermal
[12:25] <adamgreig> yea
[12:26] <eroomde> then you can assume all the sensors are seeing the same excitation at their terminals
[12:26] <eroomde> lunchtime bbl
[12:26] <eroomde> like i say, we generall don't bother doing sense measurement at the terminals on basical stuff
[12:26] <eroomde> only where we are shotting for better than 0.1% accuracy
[12:26] <eroomde> shooting*
[12:26] <adamgreig> right
[12:27] <adamgreig> will probably just hook the excitation net post-polyfuse to the VREF+ on the ADC
[12:27] <eroomde> but many pressure sensors are only rated to like 0.5% linearity so it's hardly worth it for those
[12:27] <eroomde> yeah that's a good idea
[12:27] <eroomde> (post fuse)
[12:27] <adamgreig> we have a separate PSU module from the datalogging module in this stack of quite space constrained avionics, so can probably have the PSU people fuse and maybe isolate the excitation supply to the DL
[12:28] <adamgreig> datalogger*
[12:28] <eroomde> because we do +/- 10V excitation on our boards, obviously i can't put that into a 2v5 ac ref
[12:28] <AndyEsser> eroomde: I imagine at some point I'm going to come and ask you many questions about sensors :)
[12:28] <eroomde> so i multiply up the 2v5 vref to get the 10 (and -10). But it staisfies the ratiometric assumption either way
[12:28] <adamgreig> suspect this will be 3v3 excitation for simplicity but could do 10V DC probably to be honest
[12:28] <adamgreig> but yea could divide that to get the vref+ or something
[12:28] <eroomde> for embedded flight hardware single rail is probably A Nice Thing if you can get away with it
[12:29] <adamgreig> yes
[12:29] <eroomde> in a wee rocket
[12:29] <eroomde> really really brb
[12:29] <eroomde> lunch
[12:29] <adamgreig> martlet 2 had single rail 3v3 excitation for the strain gauges and worked pretty well
[12:29] <adamgreig> seeya
[12:29] <adamgreig> (but that 3v3 was the same as the analogue supply to the stm32 and if it went down, so did the PLL running the clock, which was a scary sort of failure mode)

[16:02] <daveake> it's ez
[16:03] <fsphil> eh zed, eh
[16:03] <Ian_> Lol. A good few years ago there was a RAF engineering publication "Getting it right first time" (or some such) Version 2.
[16:03] <fsphil> haha
[16:03] <AndyEsser> haha
[16:04] <eroomde> i have a book called 'right the first time'
[16:04] <eroomde> but it's about high speed pcb design
[16:06] <Ian_> Design of high speed PCBs or designing PCBs at high speed . . .
[16:06] <Ian_> or both?
[16:08] <eroomde> i think the former
[16:08] <eroomde> getting it right the first time with design usually means not being high speed
[16:08] <eroomde> but doing a lot of analysis
[16:09] <eroomde> it's usually much slower and more expensive that doing a good first pass prototype, getting it fabbed, and then testing
[16:09] <eroomde> and then having a v2
[16:09] <R34lB0rg> a useful book may contain some tricks to avoid certain problems
[16:09] <eroomde> i prefer the latter but lots of people get fixed on the former
[16:09] <eroomde> as if one is building an airliner
[16:09] <eroomde> thank you for that insight R34lB0rg
[16:16] <eroomde> adamgreig: vim + tmux + tslime allows you to, for example, have a pane with vim and a pane with ipython, and tslime lets you paste snippets into another pane. So you can set it up to, whilst in vim, copy and paste some chunk of python into an open ipython session
[16:16] <eroomde> really good for getting functions and larger code blocks in
[16:17] <eroomde> tslime will do whatever is highlighted in visual mode
[16:17] <eroomde> or the default is the current block
[16:17] <eroomde> equivalent to vip in vim i guess
[16:17] <eroomde> or you can do it just the current line with another command
[16:18] <eroomde> anyway i've found it a nice middle ground between just writing a 'proper' module in vim and dicking around with everything-global very expeirmentally in notebook

[21:10] <fsphil> just as well I've never had to name a kid
[21:12] <fsphil> I'd be terrible at it
[21:12] <Ian_> Your time will come . . .
[21:12] <eroomde> some of our research engines were called STERN, STRICT, and STOIC
[21:12] <fsphil> dunno. I like having free time
[21:12] <eroomde> one nameless person was quite insistant that the next be SPANK
[21:12] <fsphil> hah
[21:13] <Ian_> As for jumper wires, they just hide on breadboards languishing in corners
[21:15] clopez (~tau@neutrino.es) left irc: Ping timeout: 256 seconds
[21:16] <fsphil> probably quite a few in the drawers of unspeakable mess
[21:16] <Oddstr13> :3
[21:16] <fsphil> I've been meaning to go through them since I moved house
[21:16] <eroomde> hiding with the sharpies

[21:28] <Ian_> You won't go through them, they will slowly become unaccessible . . .
[21:29] <fsphil> the plan is to buy some small boxes and separate out all the bits
[21:29] <Ian_> You will re-purchase components and tools rather than begin an expedition to find them
[21:29] <fsphil> sadly I have done that
[21:29] <fsphil> more than once
[21:29] <Ian_> Planning is futile!
[21:29] <fsphil> and probably dump a lot of it
[21:29] <fsphil> I don't need 10 VGA cables
[21:30] <Ian_> Sacrilege surely, next you will be eschewing instead of chewing bacon butties
[21:31] <fsphil> probably don't need that stack of 6 freeview receivers in the bottom shelf
[21:32] <Ian_> I bet they were bargains in their day
[21:32] <fsphil> yeah. and they all got good use
[21:32] <fsphil> from before tvs had dvb-t receivers builtin

[22:44] <Vaizki> I just assembled the desk
[22:44] <fsphil> looking good
[22:45] <Vaizki> and yes thats an old russian Selena radio
[22:46] <Vaizki> now I need a decent bench DMM.. the hameg one is pretty horrible

[22:48] <Vaizki> the cellular test set has spectrum analyzer, power metering, 2 rf generators and audio analysis all in one
[22:49] <Vaizki> and it will tell you if your mobile phone meets the GSM radio specs... :)
[22:50] <fsphil> hah
[22:50] <fsphil> you can setup nano-nokia
[22:51] <fsphil> bench dmm is probably my next thing
[22:55] <Vaizki> yea I didnt really have a good place to keep a bench dmm before
[22:55] <Vaizki> the desk is new (to me)
[22:59] <Vaizki> my GPSDO is not locking from the window in this room though... thats a pain
