Hey folks.
I've decided to build myself one of those helmet drying/cooling fans and I thought I would share it with you.

Got from Jaycar a laptop cooling fan unit $12, a 240v electric fan $29 and a rocker switch with light indicator.
Removed the original fan and attached the 240v and the light switch. Decide to glue the indicator instead cut the acrylic (just lazy)

A bit of Google search and learned how to wire it properly without blowing things up.

Its not the prettiest or hi tech but it will do the work for less than $60
