GPS unit with MPH and multiple trip meters. This is an ongoing project that is to the point that I need to be able to actually take it somewhere. I built this case to house the components with a little extra room for more. Still a lot to figure out and a lot of programming to figure out. It can be powered through the USB cable, a battery pack, or plugged into a car.

Since it will be plugged into an automotive charging system, I built this voltage regulator to make the voltage a constant 6.5 volts.
