Yeah, we use diver drops and rub them on the inside of the lends to prevent fog, but sometimes it just isn't enough haha.

Thanks for the reply and for the welcome! I have a few questions though: - What is a rheostat? - Does my setup look like it should work without a problem? I'm worried about burning it the fan, or having my LiPo explode on my head. But to clarify, the holes would be facing the inside of the lens, therefore blowing directly into the lens. Also, the pair of goggles I am using has a design where the lens is actually lifted a good 3mm off the frame of the goggles so let air in and escape. Also, I'm only using these goggles for about 20-30 mins at a time during normal gameplay. But for longer Operations it might pose a problem. That's where the trial and error comes in! lol

Disclaimer: I am not a trooper. However, even though I didn't know this kind of thing existed until a few mine ago, I absolutely love it! I stumbled across your forums and got inspired! Teach me your ways! Hello Everyone! So as stated above, I got inspired to implement your ideas into a hobby of mine that is plagued with the pesky issue of goggle fogging. I am an avid Airsofter and am heavily involved in Milsim (military simulation). I have been looking for a DIY way to permanently address the fogging issue. I have concluded that the pair that I use requires constant airflow through the lens to keep it 100% fog-free. I came across your ideas for cooling down your helmets using small computer blower fans! I want to use these blower fans to provide that constant airflow. Here is the fan I have in my amazon cart: (http://www.amazon.com/uxcell%C2%AE-FSY51B12L-50x15mm-Brushless-Cooling/dp/B00MJUD1DW?ie=UTF8&psc=1&redirect=true&ref_=ox_sc_act_title_1&smid=A1THAZDOWP300U). It is a 12v 0.10A DC Cooling Blower Fan 50x50x15mm. I have at my disposal a 2s 7.4v 500mAh 20C lipo battery pack that I want to use to power it. I will strap this whole thing to the strap of my goggles behind my head and direct the airflow using a flexible tube that wraps around the straight, enters into the goggles spanning the full arc where the air will exit through hole drilled into the goggles directing the air straight onto the lens. A few questions: - Can I just solder the fan directly to an on/off switch, solder on some connections, plug in my battery, turn it on and forget it? - Do I need to regulate the power? (I would actually like do be able to adjust the RPM is that is at all possible. Any ideas would be greatly appreciated!) - Should I use a 12v or a 5v fan? Why? - Am I even on the right track? I will provide any additional information as needed. Thank you so much for your time and input! I really appreciate it guys!
