Maker Faire – new project!

I just found out that I am exhibiting at the Bay Area Maker Faire!
I applied after the deadline and was accepted as a last-minute entry. So I will make something new to show and also bring a couple of 2010 pieces.
The new thing that I am conceptualizing has something to do with software-less lighting controls and also something to do with ears. So the first thing is to go into my attic and see what EAR related supplies there are already.
My attic has some pretty cool stuff stored in it. There are a few animatronic puppets, ice sculpture supplies, random motors and quite a few lifecasts of various body parts.

But I am only looking for ear molds. Luckily I find a silicone mold and cast an ear!
The first casting comes out filthy and full of bubbles.

Later on….
