In-dash carputer + audio build
Thanks for the info! I had thought about going with a Unix OS, but EvoScan is a Windows only application, and I wasn't sure about Unix drivers for the OpenPort 2.0. Being able to tie in all of my gauges was a priority for me. Even though I am a Software Engineer, I didn't want to have to take the time to write any drivers or such myself.
I'd probably try to run it through a VM and see if that works. Unless someone already knows. It's really more of a bonus to me running directly from the battery to the computer. Since it has such a small draw, it would take this thing a few days to kill the battery. I can just leave it on. Windows is beyond running on a 500mhz system in 2012. Unix runs great and even has decent OpenGL performance to build a snazzy interface. But yeah I can see running Windows too since the Evoscan gauges are cool when tuning. I used to just plug my laptop into the flip-out DVD screen when it was in the car.
By the way I picked up my hardware at mini-box.com if you want to go take a look.
I just finished my Carputer:

I imagine you could tap off the voltage supplying the overhead lights and use it with the ACC relay wire with a couple diodes. If the overhead lights are not 12V, then you can adjust the M4 IGN SENSE voltage down to whatever it is.
Or you can use Linux.
I have one of these that boots in 10 seconds from receiving VCC. (from a stock Slackware Linux install it was about 2.5 minutes before I went to work optimizing everything under the sun)
500mhz AMD Geode x86 CPU.
256mb ram
compact flash slot on the board for the OS (using an old 256mb card myself)

I customized Slackware Linux and manually rewrote the boot init system. Custom compiled the kernel removing module support and only compiling the exact hardware drivers it needs. Even though it's a compact flash card from the late 90's (horribly slow), it's still OpenGL ready and fully booted after 10 seconds. With a real harddrive I bet 5 seconds is achievable.
If you get one let me know and I'll DD the flash ROM and share it up. Just needs someone to write a front end because I never got around to it. Lost interest after selling my IX. I may pick it up again one of these days after I finish some other side projects. Obviously linux lacks EcuFlash/Evoscan support but the OP2.0 standalone logging is all I use anyways these days. I use an EEEPC running XP to flash.
Anyways your install looks good. Props!
