In terms of an Uzi shell I did find these things:

Slightly more expensive and obviously hideous in color, but they are much sturdier, already have a gigantic barrel and run on what looks like a 2.6v usb rechargable lipo that could be re-purposed to power the wiimote. The laser pointer and flip out stock are a nice bonus as well. My only concern is how difficult it'd be to gut. I'm sure they have more complex innards than a squirt gun.

This one looks similar, so it might give you an idea as to what you'd run into:

Nice find on the mongo solenoid. That one looks formidable enough to give a good kick. Just a couple of suggestions though. Don't skimp on the power supply and go bigger than you think you will need, even for the smaller ones. A lot of those cheap supplies don't even come close to what they are supposed to be rated for, and pop as soon as the current draw goes above about half.

And on the driver, a relay might not be the best choice. In a gun, it's going to get cycled a lot and if those contacts spark at all, it won't be long before they get carbonized, burn up, or unrelated to that, the mechanical parts give out.

So long as the solenoid pulls less than 5A and uses less than 24v (according to the specs) and you add a heatsink, this could work and it might even be smaller:

Sweet.

Howard_Casto:
Heh, I'm out of wire of all things. I'll go pick up some cheap speaker wire tomorrow at walmart. I don't know if I'll get time to rig something up though.

Picked up some wire this evening but I was dog tired by the time I got home. Oh well, it'll keep till later. Actually the inside of that gun looks more ideal than I thought it'd be. All the splatter parts seem to be housed inside its own inner shell and the cavity it leaves behind looks suspiciously wiimote shaped. The barrel length it has would be almost perfect with a wide angle lense stuck to the front of the wiimote. There are actually a lot of these splatter ball guns on Amazon for reasonable prices.... I feel like there are more than a few good options out there. I've saw a few with an optional secondary handle that bolts where the sight is and that'd be good for some of the later games like aliens extermination which have a rocket/bomb button AND a second trigger on the front handle for a flame thrower. Yeah a mosfet might be the way to go, I'm just unfamiliar with their usage when it comes to active high vs active low. I wouldn't think it would make much difference considering what they do.
