I've thought of an awesome project (assuming the vauxhall ecospastic semi-auto actuators are fast enough):

Raspberry Pi controlled, semi-auto shifting!

Have a T-piece between the clutch master cylinder and the clutch-actuator so you can have a conventional clutch with paddle shift, semi-auto or full auto modes.

The paddles could be added to the steering wheel and the horn feed could be used (just need two different value resistors on each paddle).

hmmmmmm.. just need the time now

That's a completely terrible use for a raspberry pi.

Do you need ethernet and hdmi to your gearbox?

Loads of stuff more suited to the job.

But not stuff that I've already got in my possession..

And after witnessing how piss poor the PI is at running XBMC I dont really have a graphical application for it.

Arduino/PIC based would probably be more suited, be a lot easier to integrate for starters. Although sounds like a cool project, certainly if you go ahead with it then it'd be nice to have a build log of it

By the way, have you tried OC'ing the RPi for XMBC? As mentioned in the other thread, there's been a few people saying it makes a vast improvement.

I'm worried about heat issues, even if the chip can take it I'd be worried about heat soak on the board and what its doing to it be cool if someone made a heat sink kit

A simple Micrologix PLC would be able to do that. Although im not sure if could respond to I/O fast enough.

Heat doesn't appear to be an issue as it has been reported of people clocking them to 1GHz and the Broadcom SoC is apparently 'cool to the touch'. Overvolting would be my only concern but that's only due warranty.

Ocean - Micrologix PLC looks to be far to OTT, plus i'm sure a unit is a lot more than a 5-10 PIC development board

Maybe John/Ed can confirm, as i don't have one to play with, but everything i've read states that the SoC doesn't get hot even during heavy processing.

Mine got warm when I installed the os. Certainly not hot though - I don't think they're really meant to get hot as they're supposed to sit in phones and routers with no cooling or heat sinks.

I'm running my cable tonight, I'll try and do some more testing later.

Yea it would TBH the new Micro800 are pretty cheap for what they are. I would suggests PLC though, as i cant programe "code" for shit, yet i can programe PLC ladder code all day long!!
