    How about this? A bluetooth dongle that turns the PC on when you get near the vicinity, an unlocks the doors.

    I have that same idea written down in a notebook and I was dying trying to figure out how to use RFID within a certain distance and always get the right action (open windows / put top down on a hot day) with only a card in your wallet or something.

    On second thought, that's a much better idea, I vote for that one since SO many people would want it. Im not even willing to start tackling that project because right now theres only a bunch of small projects that can possibly be used to make this, but theres no central one. Confused? I mean like, there's bluetooth / RFID readers that are independant, then there's antennas, then there's card reader/writers, then theres bluetooth hardware stuff, then theres the actual program. All of these separate cost a lot of cashola.

This would be sweet, as an easy way to add a reversing camera to a setup. You could just put it inline with the VGA input from the PC so you don't have to worry about manuall changing inputs on the monitor.

    Search for "cheesebox" . It's a box that does just what you're saying except the auto-switch. I wired a relay that pushes the button when my backup lights go on. Works just as you desire.

    Good luck.

    Ahhhhh, I see what you're after now. Yeah it would take a lot less than one year to build I would imagine...

    Sweet, thanks for the heads up!
    I installed my carpc into my pet Kangaroo, mate.

    I'll definately look into the bluetooth key thing, but damn that thread is long, anyone has been following it please give me a recap.
    Hvac is definitely keeping in mind. Though, i'd like to ask how that would interract with our carpc? To be honest, i don't trust MS windows to control my HVAC cuz, even if its stable right now, its still crashes here and there. Hell i don't even trust PC hardware to do it, because in canada it gets below -40*C HD goes out and you got no heat control lol. IF i go with an embedded processors or such, then how much difference is it from today's automatic climate control?

    Myrus' idea sounds great, but I'm going to have to research on that before i say anything because it require a lot of component that are software engineer and related problems.

    From what I've read in that, which was a fair while ago, nobody got anywhere. There are a few premade systems using cell phones and all that jazz, but nobody actually went through with the idea of using a bluetooth or RF keychain thingy to do anything to their car. Most people don't have the electronics knowledge to program a microchip to detect something as advanced as Bluetooth or RF.

    It would interact through USB as an HID device or you could write your own drivers (unnecessary). You could wire up spare buttons to the microcontroller to serve as manual adjustments, have like 5 presets! You could make a really slim little faceplate and nobody would know it's there. If your computer crashes or wont start, the microcontroller is still waiting for input, so you could press a low-profile button to turn on the heat, or crank the AC depending on weather. The difference is that you have complete control over every aspect, you don't have to use the car's limited controls. If you wanted the blower on half power, you could do that. If you wanted certain vents open and other ones closed, you could do that. If you want some crazy temperature controls, you can do that. See my point?

    Not exactly carpc related, but just another idea to throw in...active noise cancelling.

    You could have a device which goes inline between the line in and the amp. This would allow all your music to go through, yet the device would also add an inverted stream of the road noise to be played through the amp. Sounds simple enough to invert a wave, but not sure if something like this can easily be designed.
