I've been interested in reading my vechicle's OBD-II interface for a while, thinking that the Empeg's screen would be a great display conduit for it.I found a site, ScanTool that makes and sells a PC interface for the three type of OBD-II interfaces.

The best part is that instead of paying $150 or so, they GIVE you the schematics, and you can buy everything seperately, and make it yourself.

Add this to my external VFD project, and you have a small HUP for your car's vitals!

Of course, there's only a small 'set' of commands that are common from car-to-car, so some type of database would have to be set up in the way of 'commands', 'descriptions', and 'result', but it could probably be done..

The only REAL problem?
The empeg dosn't have enough SERIAL ports! Can't use my external display WITH the OBD-II, unfortunately..

Darn.
Me.
