Next up is cooling fans, i used two 5v blower fans connected to a battery pack containing x3 1.5v AA batteries.
I used jst connectors on all connections for servicing.
The fans are attached with Velcro which allows me to reposition them as needed.
At the moment I have them pointed the same direction to create good airflow around the helmet, these fans can really blow!
I added connectors to the Kropserkel battery pack, moved it back more, removed the sticky back Velcro from the battery unit lid and attached new Velcro to the back of the battery unit, I also removed the switch and relocated it next to the fan switch so it is easier to access.
I fabricated a switch structure from plasticard to accommodate both micro switches.
All done!
