This is a simple machine that plays tic tac toe. It was made mostly form dead electronics, like a printer and a DVD reader.
How it works: First we have to put our mark, it is a black square of cardboard, then by pushing a button we send the information that we are ready (if you want the machine to star just press the button without putting any piece). The the machine scans the board using Ir light witch will not be reflected over our piece. The the machine goes to the last step we it decides where put its mark and the cycle repeats until it detects a winner.

Step 1: Stuff You Need

Basically you just need a dead printer and a dead DVD reader. The motor witch works with the cartridges in the printer and the one witch works with the laser in the DVD reader have to be bipolar steppers motors, so be sure of that.
The plastic parts where taken from the plastic of the printer, be sure to find some straight sheets a cut them from there.
Great project, nice recycling. Could you speed up the checking code by finishing the check sequence as soon as a new piece is found as there will only be one new piece each turn.
Buen trabajo amigo... para jugar solitario :) Saludos desde Chile
