A couple of weeks ago, I Ebayed an OEM GPS module for $25, including shipping. Then about a week ago, I picked up a Mighty Mouse II from Tri-M Systems. Today, I finally got around to hooking them up. Using a breadbaord, a 5-volt regulator, a 6-volt power supply, a wire wrapper, and a good supply of wirewrap and other wires, I finally hooked it all up today. The result: incoming NMEA data words at 4800 Baud!

I quickly found some free (as in beer) software to help me make sense out of it. VisualGPS showed up in Google, and is working well. See a screenshot below.

This is all in preperation for an entry to the Seattle Robotics Society‘s Robo-Magellan.

Here are some pictures of the setup:

    Cool! The diagnostic program that came with my GPS wasn’t nearly as good as Visual GPS. I am downloading it now. Their NMEA time program looks promising too.
