HOWTO: Budget cooling system for Stormtrooper helmet


Recommended Posts

This is a quick show of budget cooling system for my Stormtrooper helmet. I've always wanted to use rechargeable batteries and this way I have enough power for all-day trooping and battery is stored inside chest (USB cord is long enough). 5V computer fan taken from old laptop, any USB cable and USB power bank. You only need scalpel and 30mins of spare time to make it. Mtfbwy!
 
Total cost (if buying new, I had all the parts already):
1x 5V PC (turbine) fan 50mm x 10mm = $1-5
1x USB cable = $1
1x USB Power Bank = $4-20

Nice! I've ordered a couple of those little fans on ebay for £1.50 each. I WAS going to use a 4x AA holder and switch, but I have a couple of these little power units that never get used, so might try this!

It seems this fan is not perfect fit for helmet, therefore I bought smaller one on eBay for $1.50 and will make another video (and post here) when it arrives. To partially answer your question - I do plan to use self-adhesing velcro inside helmet with new black USB wire.
