Making My Own Goggle Fan.

[rayko]

In fairness, goggle fans are really there to keep your lens or glasses from steaming up, which is what they do. Blowing a breeze into your frame to keep you cool is a side effect.

If you go down the big CPU fan route, you'll dry your eyeballs up and get conjunctivitis.

Using the fine mist route will, I guess lower what you can see (you're spraying water into eyes and misting the inside of the lens), and probably increase the relative humidity inside the frame, creating a micro climate due to a lack of 'through' breeze. Good for tomatoes and cucumbers though

Keep going though, sounds like an interesting project.

I tried a fan the same size as that Olly, it looks like it at least, except i had 6 times the voltage. Really didn't think it was enough.
Although in fairness of the test, it did have 3 LED's on it.

Thats something I didn't think about Rayko, effects of alot of passing air on your eyes, and you sound like you are right too. Perhaps I should stand around and see how much I can take before I lose my sight Well, with a 60x60mm fan, it should be less air, and maybe even I could make a circuit to make it on for 10 seconds, then off for 10, and repeat. Could mess around with these variables to find out a real nice combination that keeps you feeling cool and refreshed, while still keeping your vision - Battery life too

It depends- the little funnel those fans sit on directs the air into the lense space and stops fogging, but if you want to feel cool and refreshed whilst wearing paintball goggles you might be out of luck. I use two of the above on a set of Profilers for all-day big games etc and they work very well

after reading this i had a play with a 50x50 cpu fan and my dye invision mask and it works quite well.

I have put the switch on the side to avoid hits and powered off a 9v bettery

fits fine and keeps a steady breeze blowing throuth the mask

 

[Ahdinko]

Where did you put the fan, and how have you attached the fan to your mask?

I might have a look at one of these, marshalling the big game, was killing me how hot it was & it wasn't even as hot as last year

 

[Ahdinko]

Brought a few different resistors, battery snaps and switches today, will play around and see which resistor values slow it enough to save battery, but still keep you nice 'n' cool. Hooked up the fan again and lets see how long it goes for.

i attached the fan to the face plate bit with cable ties goin through the vents

Got my 60x60mm fan in now, it pushes through plenty of air. Brilliant. After sunday my project should be complete

 

[ac86]

have added a fan to my mask, after it constantly fogged up at braveheart.

its a proto switch EL mask

basically, it uses a 40x40mm computer fan. because of the layout of the mask, it cant go directly above the air vents because there isnt enough room, so its cable tied to the mask as close to the visor as possible (there is about a 4mm gap). air is directed down via a bit of plastic that was bent to shape. unfortunatly, due to space, only about 25% of the air from the fan is directed down. the rest just blows up againt the pastic, but its still got enough airflow to keep them fog free (the big test will be at ancaster next month). as for power, its fed from a 9V battery. will be re-chargeable once i get round to getting one. this is cable tied on the inside of the mask (there is just enough room for it). there is a small slide switch also cable tied on the inside of the mask.

got no pics but ill try and get some later. if anyone is goin to ancaster and wants to see it, just find me
