[08:06] <costyn> oh you guys XD
[08:11] <costyn> Upu: I'm not getting any response from the GPS: B562624240FFFF63000010270050FA0FA06402C10000000000000016DC * Reading ACK response: (FAILED!)
[08:11] <costyn> Upu: maybe I fried it with static or my wiring is wrong?
[08:13] <gonzo_> I tested my comms initially by just looking for the ack with a scope. Before I wrote code to deal with the ack
[08:14] <costyn> gonzo_: I don't have a scope here unfortunately. there's one at my hackerspace though ; i could give that a go
[08:14] <costyn> I only need vcc/gnd and tx/rx wired up right
[08:15] <costyn> time/vbck/scl/sca needn't be connected right?
[08:15] <gonzo_> is that the ublock?
[08:15] <costyn> yes
[08:15] <costyn> on one of upu's breakouts
[08:15] <gonzo_> yep, just the 4 you mentioned
[08:15] <costyn> I have a second one here, I could try that one and see if I get a different response
[08:16] <gonzo_> I only used the nmea mode, but send a mode setting command to it periodically.
[08:17] <gonzo_> from mem, the only response I would get to a binary set command would be an ack. If it failed to hear/decode the setting pkt I would not get any comms back. So a noddy scope did that job
[08:18] <fsphil> I'd check if you where at least receiving the nmea data
[08:18] <costyn> fsphil: I don't seem to be getting any response from the gps
[08:20] <fsphil> rx and tx the right way around?
[08:22] <costyn> the labels for the serial interface are a little wonky on the pro min

[08:41] <costyn> it workz
[08:42] <fsphil> how how? :)
[08:42] <costyn> fsphil: by not using GND as ground, but using BLK as ground
[08:43] <UpuWork> odd
[08:43] <UpuWork> was about to say
[08:43] <costyn> apparently GND = VCC = CTS (as labellend correctly on the FTDI)
[08:43] <UpuWork> gnd = vcc ?
[08:43] <UpuWork> vss maybe
[08:43] <costyn> http://arduino.cc/en/Main/ArduinoBoardProMini
[08:44] <costyn> if I measure GND and VCC on the left hand side, get almost no voltage difference
[08:44] <costyn> 3.3v is between vcc and BLK
[08:44] <UpuWork> BLK is GND
[08:45] <costyn> the corresponding pin to GND (on the pro mini) on the FTDI is labelled CTS
[08:45] <UpuWork> well no idea at but if it works
[08:45] <costyn> UpuWork: yes, BLK is GND and now the GPS is working fine
[08:45] <costyn> still mystified why they labelled the CTS pin as GND
[08:47] <costyn> doing a little googling now
[08:50] <costyn> the GND pin on the left row is not connected to the other GND pins on the pro min
[08:50] <costyn> i
[08:50] <daveake> ???
[08:51] <daveake> On the ones I've used, there's a GND pin on each side, and they're both connected together
[08:51] <costyn> daveake: in this pic: http://arduino.cc/en/Main/ArduinoBoardProMini top and bottom row GNDs are connected
[08:51] <daveake> Or do you mean a "GND" pin on the GPS?
[08:51] <daveake> yes
[08:51] <costyn> daveake: but the GND pin on the left side is CTS not GND
[08:51] <daveake> Ah
[08:52] <daveake> Never used that
[08:52] <costyn> well i thought GND = GND, but apparently not :)
[08:52] <daveake> Well, I plug the programmer in there, but otherwise don't use it
[08:52] <costyn> BLK = GND :)
[08:53] <daveake> I have a vague recollection of buzzing out that ened to make sure I plugged the programmer in first time
[08:53] <daveake> "in correctly"

[08:56] <daveake> Well I've just buzzed out 2 boards, and both have BLK and GND on that row connected to the other GND pins
[08:56] <costyn> interesting
[08:56] <daveake> I see :)
[08:56] <costyn> maybe my cheap chinese copy has some "issues"
[08:56] <daveake> One of these is a cheap chinese copy
[08:57] <UpuWork> Its the one with the GPS module on for sure
[08:58] <costyn> daveake: you're right, on my official sparkfun one GND is connected to BLK
[08:58] <costyn> and the other GND pings
[08:58] <costyn> pins
[08:58] <costyn> strange
[08:59] <costyn> oh well

[11:41] <Randomskk> it was amusing if nothing else

[14:56] <eroomde> remember the advice i gave you
[14:57] <eroomde> if you're not going to use a parachute on your payload, you'll want to find some other way to improvestability, eg by bringing the centre of gravity forward and putting something aerodynamic on the front
[14:57] <eroomde> the best way to do this is to make the antenne out of machines solid metal bar
[14:57] <daveake> with a spike?

[15:13] <eroomde> that sounds obtuse
[15:14] <eroomde> but, the fpu is a huge boon
[15:14] <eroomde> it can means hundreds of times the flops of an otherwise similar(but fpu-less architecture) of the same speed
[15:15] <eroomde> which is useful for all sorts of dsp things
[15:15] <nick_> OK
[15:15] <eroomde> and control (which is dsp really anyway)

[15:16] Action: Laurenceb is running chibios
[15:16] <Laurenceb> on F4
[15:16] <eroomde> bigger than that and you start getting into more complicated power hungry features who archituecture is designed with operating systems in mind

[15:16] <nick_> Sorry, ADC
[15:16] <eroomde> limited in what way?
[15:17] <nick_> Speed wise
[15:17] <eroomde> well, one can buy adcs whose sample rate his higher than the clock speed of the chip
[15:17] <eroomde> so adc technology isn;t really a limiting factor
[15:17] <Laurenceb> *cough* stm32f3
[15:17] <Laurenceb> has crazy fast adc
[15:18] <eroomde> the onboard peripherals are there for convenience. they're for the 80% use case, constrained by cost
[15:18] <Laurenceb> coming out in a week or so aiui
[15:18] <eroomde> but it's no bigger to get external stuff if your requirements are more specific
[15:19] <nick_> OK, so you just use external ADCs?
[15:19] <eroomde> biggy*

[15:20] <eroomde> there's no way i can give you an answer for such a general convo
[15:20] Action: nick_ is thinking about his cosmic ray detector
[15:20] <eroomde> it might be that you need one sample per second only and do a huge amount of dsp in between

[15:21] <eroomde> ?
[15:21] <nick_> Not 4ns

[15:25] earthshine (~Mike@cpc1-orpi1-0-0-cust99.2-3.cable.virginmedia.com) joined #highaltitude.
[15:25] <eroomde> hmm
[15:25] <eroomde> so that could be quite a sample rate you need
[15:25] <nick_> So previously I looked at some fash ADCs
[15:25] <nick_> fast
[15:26] <nick_> That could buffer a few measurements
[15:26] <Randomskk> you could just do a max detect and reset or something
[15:26] <Randomskk> brb
[15:27] <eroomde> yeah, i'm just wondering about a fast adc into a circular buffer
[15:28] <eroomde> and some means of detecting something (eg threshold)
[15:28] <eroomde> which would then let you dump the previous 5uS of samples, say
[15:29] <nick_> Yeah, I was thinking that, essentially
[15:29] <nick_> Although I thought I would be limited to some small number of samples (<10)
[15:30] <nick_> Then some quick signal processing to decide whether it really was a signal pulse, and if so the amplitude
[15:30] <eroomde> no reason you need to be
[15:30] Penfold (~mike@ left irc: Ping timeout: 252 seconds
[15:30] <eroomde> what makes it a singal pulse as opposed to something else - shape?
[15:30] <nick_> If I could do that in a relatively cheap way then I think there's a number of people who'd want it
[15:31] <nick_> Noise is fast spikes, the pulse is an exponential
[15:31] <nick_> (maybe with a secondary exponential added)
[15:31] <Laurenceb> eroomde: the stm32 adc has auto threshold
[15:32] <Laurenceb> that can trigger an interrupt
[15:32] <eroomde> nick_: h'ok
[15:32] <eroomde> so
[15:32] <eroomde> the nice thing is that you might be able to test signal vs spike with a low pass filter
[15:32] <eroomde> the low pass filter will also introduce a time lag
[15:32] <fsphil> eroomde: have you got one of those cubieboards?
[15:33] <eroomde> so, by the time the low pass filter gets above a threshold (to indicate yes i am a signal) then the actual signal might have just about gone
[15:34] <eroomde> that means you could use the secondary LPF signal detection circuit to trigger the dumping of the circular buffer to non volatile memory
[15:34] <eroomde> http://www.maxim-ic.com/datasheet/index.mvp/id/2026
[15:34] <nick_> (note that cheap is relative to ~$1k)
[15:35] <Laurenceb> you could do that on stm32 using two adcs
[15:35] <Laurenceb> first does circular buffer and second has threshold
[15:35] <eroomde> fsphil: no
[15:35] <eroomde> Laurenceb: what is the speed of the adcs?

[15:36] <Laurenceb> F3 is 20Msps
[15:36] <eroomde> if nick wants to actually get proper shape info about a 100ns pulse
[15:36] <Laurenceb> but still not close
[15:37] <Laurenceb> eeek
[15:37] <eroomde> note that shape, especially on the rising edges, will require v careful circuit design and layout before that's very rf
[15:37] <eroomde> because*
[15:37] <Laurenceb> indeed
[15:38] <Laurenceb> hmm i cant be bothered to read datasheets
[15:38] <Laurenceb> but i dont think its possible with stm32f3
[15:38] <nick_> The acutal shape may not be required
[15:38] <Laurenceb> unless you can live with 50ns resolution
[15:39] <nick_> Just enough shape info to get a decent amplitude resolution knowing what the shape is
[15:39] <Laurenceb> ah
[15:39] <Laurenceb> in that case doesnt low pass help you?
[15:39] <eroomde> that depends on the shape really
[15:39] <eroomde> if it's a gaussian, happy days
[15:39] <eroomde> if it's wierd and multi-model, need loads samples per pulse
[15:40] <nick_> I can't slow it down too much, because there's likely a decent rate of these signals
[15:41] <nick_> Although really I should get on with my real work, not sit around thinking about something that could be a post doc problem
[15:41] <eroomde> nick_: http://uk.farnell.com/analog-devices/ad9484bcpz-500/adc-8bit-500msps-56lfcsp/dp/1903605?Ntt=ad9484
[15:41] <eroomde> that'd probably do ya
[15:45] <Laurenceb> wait
[15:45] <Laurenceb> cant you use an op amp integrator?
[15:45] <Laurenceb> "Data Interface: Serial, SPI"
[15:45] <Laurenceb> the hell
[15:45] <Laurenceb> at 4Ghz? i dont think so
[15:45] <eroomde> farnell is often confused
[15:46] <eroomde> tend to ignore it
[15:46] <Laurenceb> yeah mouser has the best search
[15:46] <nick_> The serial port is for config
[15:47] <Laurenceb> yeah
[15:47] <Laurenceb> why not opamp integrator?
[15:47] <eroomde> adc -> fpga -> double ported ram -> raspi or whatever
[15:47] <Laurenceb> or have i misunderstood the point of all this?
[15:47] <Laurenceb> lol
[15:47] <eroomde> would be my first order rough stab at a way of doing it
[15:47] <Laurenceb> overkill much
[15:48] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) joined #highaltitude.
[15:48] <Laurenceb> so, why not opamp integrator?
[15:48] <eroomde> why an op amp integrator?
[15:48] <Laurenceb> i dont know lol
[15:49] <Laurenceb> what do you want to know?
[15:49] <eroomde> why would you use that to sample the shape of a pulse any more than you would use a toothbrush of a spandau ballet cd?
[15:49] <Laurenceb> lmao
[15:49] <eroomde> or a*
[15:49] <Laurenceb> nick_: was indicating pulse area was interesting
[15:49] <Laurenceb> integration gives you that
[15:49] <eroomde> yes true
[15:49] <nick_> It is, but shape is needed too
[15:49] <Laurenceb> hmm
[15:49] <nick_> One of the issues is that you get secondary pulses
[15:49] <Laurenceb> i see
[15:50] <nick_> So you'd like to not integrate those into your signal
[15:50] <Laurenceb> so what was the idea with the low pass about?
[15:50] <eroomde> nick_: secondary pulses from reflections due to rf or something more physical?
[15:50] <nick_> The sensor triggers itself
[15:50] <eroomde> Laurenceb: that is just as a trigger to say 'yes it's a pulse;
[15:50] <Laurenceb> ah
[15:50] <eroomde> as opposed to a noise spike
[15:50] <Laurenceb> i see
[15:51] <nick_> A breakdown in one pixel can give you a breakdown in a near pixel
[15:51] <Laurenceb> due to longer duration in a real spike?
[15:51] <eroomde> and that trigger says 'what is in the circular buffer right now is of interest'
[15:51] <eroomde> which you then dump to a flash card or whatever
[15:51] <Laurenceb> damn ill get out the F3 datasheet
[15:51] <nick_> :S
[15:51] <Laurenceb> there goes hope of getting work done

[15:55] <Laurenceb> F3 can be "overclocked" to 36Msps
[15:56] <eroomde> nick_: what's the peak amplitude you're expecting?
[15:56] <nick_> ~100mV?
[15:56] Lunar_Lander (~gd-compto@p54882963.dip.t-dialin.net) joined #highaltitude.
[15:56] <Lunar_Lander> hello
[15:57] <eroomde> nick_: ok, could be worse
[15:57] <Laurenceb> so like 33ns resolution
[15:57] <eroomde> we can deal with that
[15:57] <Lunar_Lander> daveake, as to the capacitor discussion of yesterday: I only could get a 100 uF cap for 40 V is that OK too?
[15:57] <Laurenceb> id avoid the low pass
[15:57] <daveake> What do you think?
[15:58] <Laurenceb> then just have 36msps into a circular dma buffer
[15:58] <Hix> http://www.compositestoday.com/2012/09/apple-granted-carbon-fibre-moulding-patent/
[15:58] <Laurenceb> with analogue watchdog
[15:58] <Lunar_Lander> yeah probably not that good
[15:58] <daveake> Why not?
[15:58] <Laurenceb> to trigger a mem to mem dma and isr
[15:58] <Lunar_Lander> wait
[15:58] <Lunar_Lander> 40 V is the max. voltage
[15:58] <Laurenceb> that runs on completion to look at the pulse
[15:58] Hoppo (~johnhopki@ joined #highaltitude.
[15:58] <Laurenceb> and chuck noise
[15:59] <Lunar_Lander> I also got a 200 uF Low ESR 25 V
[15:59] <daveake> Which do you think is best for your application?
[15:59] <Lunar_Lander> Low ESR is necessary
[15:59] <Lunar_Lander> and a big capacitance
[15:59] <Lunar_Lander> so I think the second one
[16:00] <daveake> And does the 40V one have it?
[16:00] <Lunar_Lander> capacitance is smaller and it is not low ESR
[16:00] <daveake> So the choice is ...?
[16:00] <Lunar_Lander> the second one
[16:01] <daveake> Excellent. I've done all the questions and you did the answer. I call that a result :D
[16:02] <Lunar_Lander> xD
[16:03] <daveake> In some circuits, too much capacitance is a problem because the inrush current (to charge up from 0V) will be relatively high for a long time, and that possibly could stop a circuit starting up or could cause something to fail.
[16:03] <daveake> Otherwise, too much capacitance and/or voltage ratings just means it's a larger component and costs more
[16:03] chris_99b (~chris_99@ joined #highaltitude.
[16:04] <daveake> I suspect that none of these are issues for your circuit

[16:05] <Laurenceb> of course you could also overclock the processor itself

[16:09] <Lunar_Lander> daveake, yeah
[16:09] <Lunar_Lander> today I saw a 68 uF capacitor for 100 V
[16:09] <Lunar_Lander> that is quite a big thing!
[16:09] <nick_> Laurenceb: what architecture is STM32F1?
[16:09] <Laurenceb> M3
[16:09] <Laurenceb> i was suggesting you use the F4, which is M4
[16:10] <daveake> Size = capacitance x voltage rating x some factor
[16:10] <Laurenceb> but its not avaliable yet
[16:10] <Laurenceb> should be in a few weeks i hope
[16:10] <nick_> OK
[16:11] <Laurenceb> ST usually handle launches of new micros quite well it seems
[16:11] <nick_> Yeah, my brain remembering m4 is kinda what sparked this
[16:11] <Laurenceb> looking at the F3 clock tree you could overclock just the adc
[16:11] <Laurenceb> to get >36Msps
[16:12] <MrScienc1Man> q
[16:12] <Laurenceb> but the memory bus might be congested
[16:12] <Laurenceb> depends how the data is packed before the dma
[16:14] Hoppo (~johnhopki@ joined #highaltitude.
[16:15] <Laurenceb> and theres no ref manual yet
[16:15] <Laurenceb> grrr
[16:15] <Laurenceb> but if you can live with ~20ns between samples it may work

[18:47] <Darkside> we'd make a beaglebone cape, with an atmega and one of these modem ICs
[18:47] <Darkside> the atmega acts as a KISS TNC, which talks to the modem IC, and talks to the beaglebone via one of the UARTS, and the beaglebone has a lot of UARTs free...
[18:47] <Darkside> unlike the rpi which has one
[18:47] <arko> sweet, post about it
[18:47] <Darkside> this will mean NO usb devices ideally
[18:48] <Darkside> though we'll likely end up using a 3g modem on the USB port
[18:48] <Darkside> arko: we will when we do it..
[18:48] <arko> :P
[18:48] <Darkside> this is like a 3rd level project at the moment
[18:48] <craag> Darkside: Where did you see about soundmodem struggling on the Pi?
[18:48] <Darkside> we have other more urgent things to do first
[18:48] <Darkside> craag: reddit iirc
[18:48] <arko> cool cool
[18:48] <craag> Mine works with about 10% load.
[18:49] <Darkside> hmm ok
[18:49] <Darkside> it could be a usb thing
[18:49] <Darkside> i know the usb stack on the rpi isn't that good, some devices seem to blow out the load
[18:49] <fsphil> actually I'm gonna solder those fuses right now
[18:49] <Darkside> like, a usb mouse for example..
[18:49] <craag> Ah ok.
[18:50] <fsphil> that board ed linked to earlier looked quite nice -- even has an lvds port so it can connect to those lovely pixel qi screens
[18:50] <Darkside> heh
[18:50] <Darkside> everyone loves the pixel qi screens
[18:50] <fsphil> my laptop screen is very difficult to read in the car
[18:50] <Darkside> i must admit, after having used a OLPC for a while, they were nice
[18:51] <Darkside> we'd use an OLPC as a tracking computer if it had a bit more grunt
[18:51] <Darkside> maybe the new version will be better
[18:51] <fsphil> you could get an old eeepc and replace the screen
[18:51] <Darkside> mm
[18:51] <Darkside> we have OLPCs available to us :_)
[18:51] <fsphil> my eee has a faulty battery so I'm not bothering
[18:51] <Darkside> shenki: has quite a few
[18:51] <fsphil> nice
[18:52] <Darkside> he did some work for them
[18:52] <fsphil> I was tempted to get the early one but they didn't seem to sell to the uk for ages iirc
[18:52] <Darkside> yeah
[18:52] <Darkside> they are interesting to use
[18:52] <Darkside> i couldn't use the keyboard for long periods of time though
[18:53] <fsphil> tiny?
[18:53] <Darkside> yeah
[18:54] <Darkside> rubber thing
[18:54] <Darkside> very resiliant, which is the whole point
[18:54] <Darkside> but not very nice to type on
[18:54] <fsphil> ah . sounds like the old spectrum computers
[18:54] <fsphil> horrible keyboards them
[18:55] <Darkside> heh
[18:55] <Darkside> anyway, the screens are nice
[18:55] <Darkside> though i've found the matte screen on my MBP works pretty well in direct sunlight
[18:55] <LazyLeopard> Ah, but not as bad as the ones on the ZX-80...
[18:55] <Darkside> not as good as the pixel qi in black/white mode, but good
[18:56] <fsphil> my thinkpad is ok when the sun is shining on it directly, but at any other angle it's impossible to see
[18:56] <fsphil> glossy screens would be evil outdoors
[18:56] <fsphil> they're bad enough indoors :)
[18:57] <Darkside> yeah
[18:57] <Darkside> my old macbook unibody had one of those screens
[18:57] <Darkside> was horribly glary

[20:26] <Darkside> oh man
[20:26] <DrLuke> haha
[20:26] <radim_OM2AMR> but Steve will be on .650 :-) anyway, we are behind the radio horizon, so we will not interfere with you
[20:26] <Darkside> i jut had an idea
[20:26] <DrLuke> more like .13369
[20:26] <daveake> oh dear
[20:26] <Darkside> one of the instructions on my payload
[20:26] <Darkside> i could make it change frequency
[20:27] <Darkside> i can't see how that could go wrong
[20:27] <Darkside> >_>
[20:27] <Randomskk> haha no not at all
[20:27] <Darkside> hehe
[20:27] <daveake> I shall keep my frequency a secret then

[20:28] <Darkside> goddamnit
[20:28] <Randomskk> the calendar only has one launch for saturday
[20:28] <Randomskk> :(
[20:28] <Darkside> i'll get that fixed in a minute, once i actually decide my payloads callsign
[20:28] <daveake> Buzz isn't showing though the doc was uploaded and it is working
[20:29] <Randomskk> let me check the launch date on it
[20:29] <daveake> I sense I'm about to be told I cocked up ...
[20:30] <Randomskk> the latest buzz doc has a launch date of yesterday
[20:30] <daveake> Ah
[20:30] <daveake> Delete it
[20:31] <daveake> I want to call it CLOUD anyway
[20:31] <Randomskk> delete, or...?
[20:31] <Randomskk> okay
[20:31] <daveake> I'll do a new doc
[20:31] <radim_OM2AMR> Steve, our sts-1 is also not there
[20:31] <Randomskk> sure
[20:31] <Randomskk> STS-1 is on the calendar at least

[21:31] <Randomskk> we're discussing this right now
[21:31] <Randomskk> try copying the dl-fldigi thing to your /Applications
[21:32] <Randomskk> LazyLeopard: would you mind seeing if this .dmg of the new dl-fldigi runs for you?
[21:32] <Hoppo> Ah, looks like I missed the start of the topic! :)
[21:32] <Randomskk> Hoppo: in the development channel, that is. considering just having --hab be default for dl-fldigi
[21:32] <Randomskk> LazyLeopard: it's test software and not for full time use, but I want to check it runs on other OS X versions
[21:32] <LazyLeopard> Ok
[21:32] <Randomskk> you'd just need to load dl-fldigi and maybe see it's getting audio okay
[21:32] <Randomskk> thanks!
[21:32] <Randomskk> https://randomskk.net/u/dl-fldigi-3.21.50.dmg
[21:32] <Randomskk> don't bother with the HAB one
[21:33] <Randomskk> just the normal dl-fldigi
[21:35] <Hoppo> yeah moved it to my apps, opens and runs, just can't see a HAB option.

[21:37] <Hoppo> Works a charm. Ta randomskk
