Recently, me and chinnerz have been having a conversation about the feasibility of a Nerf Coilgun, and we've decided to continue our conversation publicly, so that everyone can get ideas, ask questions, etc. Here's the conversation so far:
If anyone has ideas, questions, flames, etc, post away.
The conversation so far... wrote:
I'm looking into making a 4-Stage Coilgun LS at the moment (the Coilgun extends into the barrel extension). If it works, then it would definitely qualify for this gametype. It'd be so funny to see everyone fire a shot at you, then spend twenty seconds reloading.
____________
That would involve quite a bit of power (like LOTS!!), a large capacitor bank, lots of batteries, make your reload time at least 2 mins, make your gun super fragile, would involve using a metal/semi metal dart, can may hurt someone quite bad! Did i mention one short circuit and your gun becomes a fire hazard??
On a side note it would be great for S-n'-G's Razz Razz

Well hook the gun up to 2 dozen 12v RC batteries in a backpack, mount all the technology inside a foam casing inside a metal cylinder, and I'm obviously gonna give it an auto-shutoff system in case of short circut. Plus, a steel fishing weight inside a stock Streamline and bang - 160 or so foot range and able to fire about twenty magazines without reload. AND really easy to cock because no need for extra springs. It'll take a two years or so, but once done, I will have the world's most devasting Nerf gun. Also, if it works, I might be able to do a couple for other people, albeit at a high price... that said, I have no idea if it's going to work yet, or if I'll even be able to get the materials.
____________
ow thats going to be massive! Unless your 12v RC batteries are a lot smaller than mine.
Also its not the battery I'm talking about, have you seen a large capacitor shorting?? I shorted it on a metal ruler, it looks like 2 spot welds! One of my friends copped one to the elbow, burn him. Absolutely annihilated copper wire leaving one a few strands and a big black mark on the table. This much power will propel a dart 2 meters?? or at least in a 1 stage coil gun didn't embed a nail into cardboard at point blank! I'll see if i can find out how many farads it was.
Also, caps don't like being shorted out, so they may have a poor life (high running costs)

, it would be massive. But also, you could adjust range by controlling the power flow.
__________
yeah that was something we knocked up in 2 hrs. tried to get the least resistance but it was stupidly weak. if you want to get 100-150 ft, I would recommend going pneumatic or combustion. Although that AJ doesn't like me talking about making stupidly powerful guns,, so dont say you got any ideas from me Razz Razz
__________
Understood. Also, you can make a powerful coilgun, just keep piling on batteries (LOL).
__________
yeah LOL, (although that would mostly decrease charge times, piling on caps will make it stronger..... ahh you should see what happened when i added 3 caps onto a flash circuit on a camera.... the results were surprising to say the least Razz Razz good times....)
__________
Okay, remind me to pile on more Caps. Also, that would have been funny with the Camera... Anyway, as far as I can see, the only issues would be the weight (the gun alone would be about three times as heavy as a Vulcan, and the batteries... well, I wouldn't be going anywhere fast. And the fact that I'd only be able to fire darts once or twice before they became magnetised. Oh yeah, and how I'd stop the electromagnet ripping all the screws out of the gun...
___________
This rly seems like a discussion to have publicly, as i think you will get a better answer/ others may get their questions answered.
But i think you should be ok with the screws at the back of the gun, maybe you should get some plastic screws, or come up with a way of gluing the shell together.... but then it will be hard to fix anything if it becomes damaged/replace caps when they stop working...
i have held some wooden projects together using wooden dowels, maybe if you made a fiberglass/epoxy base and used wooden dowels.....
Or you make the whole gun out of wood and cardboard, not packing card but thick ridged ones which you get from art shops. IDK man, there are a few ways to do it, you will just have to see what works best for you.
_____________
A potential way to stop the screws being pulled out is to give the Electromagnet a lead casing, containing the magnetic field inside the casing
