Arduino BT CarPC power controller
I've been getting annoyed at my pc as it drains my car battery alot. I know there are plenty of alternatives but I just wanted to see if anyone has tried this or thinks its a crazy idea. I have an arduinos BT. The great thing about this device is that it can operate on a voltage as low as 1.2v. My idea is to install this in my car with the operating voltage at its lowest so that the range of the arduinos is reduced. I have a small program in the works for the arduinos(not tested yet) that will continually scan for bluetooth devices and trigger depending on the detection of my phone. The idea will be that this arduinos is always powered with a reduced bluetooth range around the car. When it detects the phone in range, It switches on the carpc on, when the phone leaves range, a timer begins that first, locks the carpc for up to 1 minute of no phone detection. If the phone remains out of range for a longer period (probably 5 minutes), the arduino will shutdown the carpc. When the phone comes into range again, It will switch on the carpc. I have been trying to work it our logically so that when I'm near the car, or walk past the car, it won't switch on and stay on.
I'm aware that their might be some security issues with my way of ding this but as the arduino only controls the PC and not the actual ignition, I don't really care about that.
Sorry about the long msg.
