Defogger fan for FPV goggles
thingiverse
I built a defogger for my Skyzone Diversity FPV goggles. I incorporated an easy to solder on/off switch and a female JST connector. Just feed 12V from your goggled PSU. Here's a link to the mini 25mm fan from ebay. http://www.ebay.ca/itm/261166958988?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT I bought a cheap dollar store LED flashlight and dismantled it to get the on/off button.
