Yes I am. Finally. After a combined two years of work. One for a paintball gun I've designed from scratch that integrates pneumatics in a way that's never been done before. The second is a drop-in replacement for the Nielsen-Kellerman CoxBox (http://www.nkhome.com/rowing/coxbox.html) that makes it completely self-contained and introduces more features with a technology that has never before been used in this application in rowing. All before the age of 17.
