Coil Gun Video - Featured on Hacked Gadgets

shoot a piece of meat with it to show some power :)

Wow thats amazingly pointless. But still pretty cool. I dont see coil guns replacing conventional guns any time soon, if at all tbh.

Anyone know what range you get from these things cos all the tests ive seen have been pretty much point blank.

Well, maybe not all that soon, but still, some day in the near future.
I mean, if a single man could make this kind of coil gun, its not like goverment's best scientist/technicians couldnt like, come up with better way to use this mechanism and stuff.

Hello, if i take 2x 100 µF 450 V capacitors , how much µF and volts will i get? is it 200 µF and 900v?

Depends on how you wire them
You'll get either 200 µF in parallell, or 0,02 µF in series if I remember my physics correctly, but the voltage never changes, since it's the mark up voltage on the capacitor (meaning that if you push more voltage into a capacitor than it is made for, it'll explode. Pretty funny prank tbh in the lab ;) Best done with small capacitor though for safety )

reminds me of the hammer gun from fear 2 that nail gun thingy

Unless the more powerful capacitors were miniaturized somehow in the near future, I can see it weighing quite a bit.... but, heck, our current weapons aren't exactly lightweight.

I don't know about the powersource being too much of a weight problem, unless you're trying to hook it up to a car battery. I can see these things relying upon rechargeable batt's, and a change-out of the battery pack would probably happen after a few reloads.

Its the prius of pistols.

A prius is not a strict electric car. It's a hybrid, so it's not a very good analogy.

I've made one of these myself, and the charging is what kills it as a useful tool. Not only can it not shoot very far, but the charging time in-between shots is like adding insult to injury.

Nice for a science/weekend project... but the tech still has a ways to go before replacing the powder. :-/

@Plystire I don't think he was being serious...
