Though it's been two months since my last post, that's actually been due to a deluge of projects, not a shortage of them. The cyclic load fatigue tester has been upgraded, both with better control software and a sturdier table. In senior design I'm working with two other students on a Thermoaccoustic engine, I'll post about that when it's further along. In experimentation I've just started on a fluid temprature regulator, a machine that cools or heats water to a desired temperature. Then there's the human powered vehicle, I'm head of the components team and we've just finished the prototype for the front wheel drive/front wheel steering drive train. I'll have picture of this all as it completes. For now, check out my Instructable, and if you have an account there, vote it up.
