Airflow for Darth Vader Helmet - Happy Halloween!

The new re-breather was too loud for helmet use, but the 40mm fans arrived in time so I got to work.

Dremel and hot glue gun, soldier iron, added some padding from cycling, using up some new RC connectors, and the critical bit - an 8mm audio plug to Vlad's Danolight battery pack for 5.5V of power.

The result is a bit noisy, but it really works! One fan blows in (top) other blows out (front vent).
