Friend of mine and I decided to take apart one of those micro R/C controllers to see what made em work. Thye're ungodly simple, and we started thinking of ideas to control it via PC. We used el-cheapo Ratshack PNP transistors to trigger the buttons when the PC's parallel port data pins send a 0 to the corresponding port for forward, back, left and right.

We've written simple code to control the car and added in some automated functions... like three point turns with a single keystroke.

All in all a fun lil project

On with pics!

This is the ripped apart controller, modified and wired to the parallel port.

Happy hacking!

he's still workin on it, but when he finishes, i'll be sure to post the new info.
