Fan+stun circuit

Unread postAuthor: sjog » Thu Feb 22, 2007 10:42 pm

Is there any reason why I can't run my fan and stun circuit on the same battery pack ? Was thinking of using 8 AA bats. to run both. Will it affect
the spark? Or damage stun circuit ?

Thanks MrCrowley
When I got stun circuit he said he uses 8 AAA's.
Are AA or AAA different? Both1.5 v Do the AA hold juice longer, being larger?

AA's just have a longer capacity. Putting them on the same circuit may cause the fan to run a little bit more slowly since the electricity would be pulsing instead of constant but I can't see why there would be a problem.

You will be fine to run both off the same power supply. I do and all that matters is the fuel combusts, and that happens. The fan will run continuously, if it pulses for .1 seconds, who cares?

Well, the fan would run continuously if you wired them parallel instead of inline. Either way, it works. Have fun making mashed taters.

Well I tried it on new gun .
It does work, of course
With stun circiut and fan it does eat batts
I thought about rechargeable bats, then I looked at my cordless drill 12V
so I'm using that bat It works great

you should use a car battery!!!!!!!....j/k of course but this is a good idea and i bet it would be cleaner than sepperate battery packs all you have to do is integrate it into a peice of your gun...preferably a handle

risto i bent clips out of lead coated copper
soldered wires
they slide over bat posts
figure + -
a spring clip that would hold a broom handle holds the bat quite nicely
my bat slides into the end of the gun looks nice painted
i'm getting ready to show my new gun, next week, and i'llhave pics of all that
