For those of you guys who have a CarPC, how did you guys make it so that the PC starts/turns off when you start the car.
Thanks

 

check out www.mp3car.com There are power supplies made for carpc with auto startup and shutoff function. There are also seperate shutoff controller that you could buy.

For my system, I am using the OPUS150 power supply. The way it is hooked up is that whenever the ignition is turned on, it will send a pulse to the on/off button of the computer. So when I start the engine, it will turn on the computer. When I turn off the ignition, the OPUS will sense the shut off and will send a pulse to the on/off button again after a preset time. I have my system set to hibernante when the on/off button is pressed.

For my carpc, the computer would hibernate 30 seconds after I turn off the key. When I restart the car, the computer will turn on and resume operation from previous state (mp3, DVD, video, navi etc).

 

I have an Opus 150 for sale. PM me if interested.
