After looking at some prison made contraband I was inspired by the innovation of inmates to make many different items with very few resources. I decided to make a prison style tattoo gun using only the materials and tools that would be available to prisoners. It took about 45 minutes to make this with only a candle and razor as tools. Materials are: cassette player motor, tape, toothbrush, Bic biro, drawing pin, sewing needle, piece of wire and of course batteries.
