i got a single fan setup and my battery tends to heat up really bad...even if the fan is off

so i have to disconnect the battery everytime

waht can i do to not have this happen???

Has anyone tried a homemade fan for a Vforce shield? Anyone?

EchoX · 08-22-2003, 02:12 PM

I have.

Don't try to simply use just one nine volt battery to power a twelve volt fan. Battery will get really hot. Thanks for the post. I was thinking i would have to get some sort of relay or something. I am glad I check this site. Now all i need is another nine volt.

Thanks

Try AA batteries. That's wat I use.

do you connect the 2 9v's in series or parallel?

Has anyone considered the possibility of running the power from a large pack of 10 subc - size cells (see R/C cars or R/C airplanes) put in a 140 rd pod?
You could get fancy and get cheap 3000 mAH NiMH's (you will put virtually no drain on them, most likely) and you could have plenty of room to mount a switch, and have any other electric stuff you wanted in there too.
Run a wire with connectors (Power Poles recomended, see www.towerhobbies.com) from the top of the pod to the mask (16 or 18ga should be enough for 2 case fans) where you can connect it to the mask by another pair of connectors.

May I reccomend Mouser Electronics at www.mouser.com . They seem to have the best selection of electronic components around. If you need it, they have it. Except Connectors.

PS: Power Poles do have no latch to keep the connector connected, but this is a good thing. We dont want the connectors ripping the wires off the batteries.

The cord from the pack to the mask would get in the way too much.

FokusFighter · 09-29-2003, 11:30 AM

has anyone ever tried some kind of mounting system right onto the mask?

just a thought but if its a couple of double As on each side it wouldn't be that bad

Hey, i just have one DC fan, and i got it to run, but how do i connect all three (battery, switch, fan)

SkunkTeeth · 10-11-2003, 11:20 PM

It matters waht type of switch, but if its a single switch (only two prongs on the bottom) do it like this

Battery(+) to switch to fan (+)
then
battery (-) to fan (-)

And heres pics of my current progress on my shield, 1" fans are in the mail, one for sucking one for blowing.

FogTech is much cheaper.

SkunkTeeth · 10-12-2003, 06:28 PM

Also more expensive, and wont last as long as a fan system. I only needed to spend $2 on my system.

themenz · 10-12-2003, 07:39 PM

Fan, switch, wiring, batteries for $2.00. I want to shop where you shop!

SkunkTeeth · 10-12-2003, 07:55 PM

Fans (2 1") 1 dollar each
switch off of some old electronic project i no longer used, tons of wire from old computer fans, and loads of rechargable batteries.

themenz · 10-13-2003, 04:08 AM

Skunkteeth, Well done on the price. But the battery you show in the pic above is not typically rechargeable.

Can you tell us what you did about the fan noise? Most people say the fans are loud enough to interfere with communications. Can you adjust the speed?

And batteries need to be replaced fairly often-sometimes during a scrim. Can you change batteries without taking off your mask?

I think most people go to fans because they found antifogs to be unreliable. What do you think?

Kowz_76 · 10-13-2003, 07:26 AM

I think you're trying way too hard to endorse that product.

It was a dead battery I just used for placement.
With a 12v fan running at 9v, there is very little noice compared to 12v, especially at 1" fans. The speed cannot currently adjusted but a small dial could be added into the circuit. I dont think I will need to change the battery in the middle of a game, I dont think it will for much in 10 minutes anyways.

skunkteeth, where are u mounting the fan? and on what kind of mask? im using a JT alpha, i was thinking about gettn a new mask...cause i ref, and my goggles always fog up, and i cant make clear calls

SkunkTeeth · 10-13-2003, 01:44 PM

V-force shield, I will post detailed pictures when the fans come and i come mount them. They are 1" fans i ordered off bgmicro that will fit perfectly above the lenses. I will have to cut a small slot out of the rubber but to big thing.
