One of the first things I did with my TK helmet was install a couple of 5v fans towards the front. Since then it's been difficult to hear while the fans are running. So then next step was a hearing aid of some sort. I know there's that guy who makes them and sells for 60 bucks on the FISD forum but that's a bit pricey for me. While wandering around a Radio Shack I stumbled upon this...
I spent about an hour and a half soldering and got this...
And installed...
Pretty cool, only problem is the noise from the fans have been amplified and I definitely can't hear anything else. Any suggestions on how to fix?
