General discussion / Re: WTF SeeedStudio?
Looking forward OPL v2!
10 most popular resistors in 0805 - 0R 20R 100R 1K 2.7K 10K 500K 1M, 10 most popular capacitors in 0805 and some dual-row headers would be amazing. 3x2, 5x2, 10x2 and 25x2 I guess. You've got some cool components in the OPL v1 already, it's just the more the better :)

Got an $11 refund.

Hopefully next time I order from Seeed this would not be an issue, with the shipping charges resolved seeedstudio woule be pretty cool.

And if they just add more components into their 'open components library' their PCBA service would be just amazing. Because a selection of TWO 0805 capacitors and ONE 0805 resistor is not cool :)

Here is my own experience:

I've contacted seeed, I will report back here once they respond to me.

Project logs / Re: rusEfi: electronic fuel injection/ignition
Sam,

You are totally right that I am not the only open ECU around, but there are details to that :)

open5xxxecu has not yet started one single engine - I believe they are having issues with Freescale proprietary eTPU unit which does not have a free toolchain. Let's hope that eventually open5xxxecu figures this one out.
openecu is not an ECU, it is a project related to reflashing of existing ECUs, I believe they only change properties but not change the firmware completely. Totally different thing.

FreeEMS is the only true & live open ECU project. They have real cars running it and they are truly a REAL deal - but I cannot agree with some of their decisions, that's why I had to start my own project a year ago. Right now I only have one car running this thing, so I still have a lot of catch-up in front of me :)

Project logs / rusEfi: electronic fuel injection/ignition
For some time now I am playing with the idea of making an open source engine control unit (ECU) - car engine management system (EMS). I have a working prototype - the project is called rusEfi.

So, for starters I would like to share the design of the injector driver module, only thing I am not sure how to make the 'first poster' filter happy :( I will try attachments.

It's a 6 channel low-side driver, it snaps right on stm32f4discovery.

We have some other modules in the works I will post more as soon as we get them tested :)
