Here is some top secret pics of one of my works in progress.
I used some of the foam block you saw in the last post to carve this. It will be a housing for an arm mounted radio frequency locator used to track down my radio emitting guerrilla sculptures. After carving the foam I than began to smooth it out and add texture by skinning it in plasticine. When It is done I will make a silicone rubber mold of the positive and make a polyurethane resin cast. After the resin model is made it will house the LCD, Arduino, and Radio receiver you see in the pic below. The LCD and speaker let you know when you are getting close to one of my radio frequency emitting sculptures. You will be able to wear the piece on your forearm.
