trying to install fans in my bucket. i know this may sound like a stupid question, but i suck when it comes to electronics, so bear with me.
i have 2 12-volt computer fans and 2 hook-ups for 9 volt batteries. the fans will be running on 6 volts less than they should be. is it safe to add another 9 volt battery, with it being 3 volts over or will i blow them?

Re: fan wiring system
This is what I use...
You can get them at the Shack:
http://www.radioshack.com/product/index ... Id=2062251
$2.59 a piece.
They hold eight AA batteries at 1.5 V per battery for a total of 12 V.
They also have that 9 V type plug that you can use your hook ups.

Re: fan wiring system
It's okay; you can overdrive the fans by 3 volts (I've done it often enough when I had my TK). The only downside will be noise (well, for those who aren't hard-of-hearing, that isDeafTrooper wrote:trying to install fans in my bucket. i know this may sound like a stupid question, but i suck when it comes to electronics, so bear with me.

). Run the wires in series (red to black, red to black) and remember to cover up and insulate any exposed wiring after you're done soldering. A short-circuit inside a helmet while you're wearing it can be a bad thing.

Re: fan wiring system
cool! thanks, guys! 
i tested out the fans i got with my hearing aid on and they were very quiet. even had the wife talk to me while wearing it and was surprised that i could understand her with them running (between my hearing and her speech impediment, conversations can be a little difficult, so it was the perfect test). thinking of adding a 3rd fan, (2 small ones blowing air out through the aerators and 1 big one blowing air in through the mouth). originally wanted 1 blowing in through the aerator but when i tested it, i couldn't feel anything. got much better results by having it sit on the mouth.
