Damn illusion, that is one hell of a setup. What do you do for a living? I'm a senior at PSU majoring in computer engineering and I'd love to start that sort of project in my car. I built a wireless controller for my underbody neons last summer. It was real ghetto because I used left over TTL ICs I had laying around but it worked. Anyhow, what language are you writing your software in? And how are you wiring up all those components to the I/O card. Are you using relays or does it output 12v?
