Re: Connecting Pi to Ultralyte lasergun

Thanks for the response.

The manual states 12v, but I don't know where this comes from. The ultralyte contains 2 C-cell (1.5v) batteries.

Re: Vehicle speed and license plate monitoring

Hi, I've seen multiple of these Speed measuring postings around the forum. From what I've read this could possibly be done with a HB100 doppler sensor. I guess when you want to capture a photo, just add fixed-focus camera and calculate the timing based on the speed as measured by the doppler sensor....
