build a prison style tattoo machine out of househeld items.
tools: needle nose pliers, knife, philips head screwdriver
parts: toothbrush, ball point pen, guitar string, mechanical pencil eraser, and electric motor from tape recorder
Step 1: Find a Motor
i found mine in a tape recording machine. I heard that tape machine motors were the standard, but i have also heard of tattoo machines made of nintendo 64 rumble pack motors. When you find your motor, rip it out and take note of the positive and negative wires. Also rip off the stock gear attached to the motor crank. You will be replacing the stock gear with a mechanical pencil eraser fitted to the guitar string needle.
