how to mount a cpu fan to a moprh mask(V-force)

[dubfunkstar]

Well you all know the question..I need some help maybe a picture to show me where to put this fan.

the fan is mounted

Okay everyone I have mounted a 12vt cpu fan to a V-force(Morph) mask.

The problem I ran itnto with the V-force unlike a JT is that it is made to fit your head damn near perfect give or take shape of the head. Morp did not leave any room to install a computer fan...So if your mask has a visor on it that is the key. You have to insert it between the visor and the mask. To keep it all together I used zip ties...but what ever you have will work I am sure....If anyone would like pictures e-mail me.

whatdya mount...a 40mm...cause theres no way in hell u fit an 80...or a 120...and howd ya power it...undervolt it with a 9volt...im interested lol

I have 2 25mm fans in my profiler. You just have to use fans that fit the application.

How did you guys power them?
I've got mine running off of a 12V keychain battery. The problem is that the fan is drawing too much current and that little battery can't keep up.

I use a 9v zip tied to the cheek area of the mask.

Li-Poly Batteries

I've used ones similar to these in the past. The people at this site are fair and honest, and will answer all sorts of questions about batteries and applications.

You MUST charge these batteries with a special charger. DO NOT charge them with a standard NiCad, NiMh or lead acid charger, they WILL ignite and burn furiously!

maybe use 2 batteries in a circut where they are only drawing off of one, but evenly. (not sure if its parallel)

I mounted a 40mm fan in my old scott mask , have it powered with 1 9volt with a on/off switch and it was held with grape wire.

I've got a 40mm, but it's a 12V, so a 9V won't cut it. I'm thinking that I'll have to run two 12Vs.

I mounted Two 1"X1" 5v fans wired in series to the top of the googles powered with one 9volt. Wire ties are your friends for this project

Dump the sunons pck up some eltas and wire them to a radio switch to adjust the voltage so you have a ensain amoutn of airflow and you can adjust how much ...

another option instead of these muffin fans i have right now that im working on a a minuture blower fan not the type you guys are thinking or use to seeing in PC Components but i also have Super lowvoltage Pelties so i can actualy run cold air or heated air into the mask on a low current

Soon as im done wiring and testing the unit i should post some pics

You might want to look at this thread http://www.automags.org/forums/showt...highlight=fans it is exactly what you are asking.

I've been fooling around with the same thing for my mask ... 2x 5v fans.

What I want is one with a good speed control, so I've been fooling around with something called "Pulse Width Modulation". You can get schematics for several different versions on-line. Basically, those fans need close to full voltage to turn, so PWM works like turning a switch on and off quickly. I originally was going to build a circuit using 2x 555 timer chips and a transistor as a relay but then I ran across a TI chip that is a PWM by itself.

Oh yeah, this would have two advantages ... 2 fans turning slowly are much more quiet (I'm a woodsballer) and the battery power would last longer.

I'll post when I have it all worked out (c:

The problem with 555 chips is that temp effects them so your Pulse modulation could be even slower or none existant with temperature swings. The thing you have to be careful about is the cost, as unless you are doing this a mask that doesn't have a makers brand fan available you could easily exceed the cost of a makers fan unit...many of the makers one's with minor modification could be made to fit other makes of goggles. This aside when I made these units back in '89 the parts were cheap to buy..got them from Tandy (which was Radio Shack in the UK) now this no longer exists here and the rise of pc use has actually made these fans more expensive..wierd but true.
