Wiring a fan into a helmet?
« on: Jan 17, 2016, 08:57 PM »
Hey everyone!

I have some basic experience with wiring lighting/switches into my costumes, but one I think I wanted to add to my kit for the next con are fans for my helmet. I found it got hot and the visor clouded up constantly.

I found a small fan (40mm x 10mm) that I would be able to easily (I think) fit inside my new helmet that is currently under construction.

This draws 5V and I was thinking of adding 2 of them.

Is there any issue and/or difference in wiring fans versus lighting and what tips to you guys have?


(P.S. I'm not committed to this fan so if you have any suggestions I am open to that too)

Wiring a fan isn't difficult at all. Just take 3 1,5V batteries or an USB powerbank for a 5v fan and it should work fine. If I may give you an advice I would use radial fans (squirrel cage fans) instead of axial fans, because the axial ones need to be placed over vents to be able to suck in the air. The radial ones can be placed on flat surfaces because they suck in air from the upside and blow it out at the side.

I'll definately check that out. Originally I planned for vents, but that seems to be a good idea.

I was asking about the wiring mainly because I was reading online that because of the current of the fans (DC) versus wiring lights that it was different and therefore had different power requirements. I do like the powerbank idea.
