check-wan Posted March 26, 2016 Report Share Posted March 26, 2016 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 = $1-51x USB cable = $11x USB Power Bank = $4-20 Quote Link to comment Share on other sites More sharing options...
humperdingle Posted March 26, 2016 Report Share Posted March 26, 2016 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!

check-wan Posted March 26, 2016 Author Report Share Posted March 26, 2016 Definately worth a try if you don't mind having power bank outside helmet. Mine is inside chest and gives more power than AA batts. Good luck with project Quote Link to comment Share on other sites More sharing options...
pigelectric Posted April 6, 2016 Report Share Posted April 6, 2016 Thanks for the post, I like the idea of using a USB & external power source for running the fan. Do you just use velcro to secure the fan in your helmet? Thanks! Quote Link to comment Share on other sites More sharing options...
check-wan Posted April 6, 2016 Author Report Share Posted April 6, 2016 (edited) 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. -------- Edited November 21, 2021 by gmrhodes13 link not working removed Quote Link to comment Share on other sites More sharing options...
