Email: gray_mack is my yahoo.com address As a hobby Gray has enjoyed a long history of electronic tinkering and design. I took a class or two in College but for the most part I enjoy electronics and hardware hacking as a hobby and not a career. I have done several PIC projects using the 16F84 and although there are better processors out there this is one of the cheapest and has a decent instruction set if your willing to write assembly. Ambitions: To learn more about mechanical design and manufacturing of mechanical parts needed to bring my ideas off the drawing board and connect it all together. http://www.robotgroup.net/gray/Zumo_01.jpg Zumo the can bot. Not much for brains he is powered by a Micropet (tm) brain with its speakers and movement coil drivers stepped up by transistors to drive the bot. Please help add to the SpyBotics page I am starting. http://www.robotgroup.net/eric/GrayPYTracks.jpg Gray & PY working on Erik's WideTrack
