noisymime, do you know anything about "Diagnostics & high speed loggers" tab of TS - do you support it? Looking to implement it in my ems would appreciate any hints :) Hey rus. I've had a high speed tooth logger in there for a while which displays 'tooth times' for the primary crank/t...

Interesting board. Honestly, it's probably not something I'd ever look to use. The price is fairly steep (relatively) and like you say, it's simply overkill. Then there's the fact that you have to mess about with their toolchain etc. Whenever I manage to find a few spare weekends (So probably about ...

For low speed, mostly power switching stuff, like this are 90 degrees really an issue? I thought they only became an issue at very high data rates.

a sacrifice for for sticking with THT for all components. Is THT really worth a sacrifice? 1206 is not much harder then THT. You're right that 1206 isn't too bad at all, the concern is that given this is meant to be a DIY type kit item, whether it would scare people off. I've (mostly) redone that b...

Well the next revision of the board is done and a small batch have been produced for testing. Final spec ended up being a little more limited than I had originally hoped, but it was a sacrifice for sticking with THT for all components. https://raw.githubusercontent.com/noisymime/speeduino/master/ref...

Time for another quick update... Progress has been really good over the last month or so with the firmware coming along nicely. Lots of testing and small improvements and things are now running really reliably with the current set of capabilities. The next board design has come ahead in leaps and bo...

Been a while between updates, so I thought I'd throw something up. Development is continuing nicely, mostly on the software side of late. The first round of testing boards worked OK, but there were definitely some issues with the design that I'll sort out for the next version. Firmware has been the ...

Just ordered some of these for injector drivers: http://www.st.com/web/en/resource/technical/document/datasheet/CD00003579.pdf $1.29 a pop in qtys 10+ from RS including free delivery. Was about the best fully protected driver I could find in that sort of price range. I don't think I missed any glari...

Mail me one of those Nissan coils one day and we'll see. Excuse the skeptic :-) If you were actually in Auckland I'd drop one in as I'm there every few months :) I would genuinely be very keen to see what your testing came up with, I've even got 2 spares. If they're rubbish I'll find something else...

Thanks Fred, your replies are ALWAYS helpful :) I'll go back and double check the datasheet for the Opto, but from memory it had a switching speed (Total rise and full time) of around 10uS, which I thought would be OK. Even at full saturation it was around 30uS. The crank sensor is definitely 12v. I...
