It's not so good in practice. I wish we had a 3d printer. BTW shout out to Tampa Bay on their communicator. Way to go guys!

Our current problem is that we keep breaking the polymer clay components of the build. It'll work great, you start fiddling with it and it breaks. Currently the game plan is to re-inforce the clay with drywall weave, and the aluminum sheeting.

As a result our design has changed almost completely. We are borrowing more from my personal development that I was going to release, but that'll be released after this. 

We have a total of 3 major parts now. The base that attaches to the article of clothing. In this base we have included the battery, speaker and amplifier circuit, which to be fair was ripped out of a walgreens hearing aide. Second we have the logic stage which sits on top and connects to the base. This stage has the BT headset board, microphone and activation buttons.

Unfortunately, getting pulled away. I'll post the new design, and pics later. I think this disqualifies us from the contest though.
