Bring on the cold! 17 blistering Watts

Smoke test! It works, nice and toasty. The wiring will be integrated with a switch (on/off heat regulation) and my heated gloves so I can simultaneously run both (I'll get to it when the snow melts). $20, 3-4 hours of labor and it works just like my buddies vests that cost well over $100! I'm now thinking I can adapt this for scuba diving and charge $200 ;-)
