I need to create a product for a small business class. It has to be a working proto type? -

I m working on a project that needs a usualable proto type. I need to be able to actually make it. What would you want if something could create it.

I d like a ring that would stop my overeating.

what about a light plastic sound absorbing helmet with built in speaker and microphone that people could wear when working around heavy machinery or in loud trucks or concerts or logging facilities... something that would allow them to use a phone around loud areas?
