And here it is, the moment you’ve all been waiting for, the one, the only… Coil Gun v2.0!!!
If you want to know how a coil gun works, or you don’t even know what a coil gun is, check out the coil gun v1.0 page here.
I was quite impressed with my first coil gun’s performance. It could pop a screw across a room, or shoot a paperclip at some kid across the classroom quite nicely, but I always dreamt of having more power. Being a university student and such, I never really had any money lying around to be able to build a more powerful version so I kinda just gave up and forgot about it for awhile. That is, until my girlfriend randomly brought up that the store she works at (Party Packagers) was trying to get rid of a whole bunch of expired disposable cameras. It was a freakin’ gift from GOD. At 1 buck each minus the 20% employee discount I had to get 13… Why 13 you ask? I have no idea, but it was probably the amount of money I had in my wallet at the time. 
The cameras sat in a bag in my room until reading week, when I set out to build my most powerful coil gun yet.
This is the story of how I built the coil gun v2.0 with step by step instructions, pictures, and video!!! (Even though I show you how to build a coil gun step by step with pictures, and video… don’t do it, they are so ridiculously powerful one wrong move and it could drop you to the floor crying like a little baby for your momma and/or kill you)
13 disposable cameras (I only ended up using 10 in the coil gun, the other 3 are for another project idea 
)
At a dollar you can’t possibly go wrong.
Comments
Hey instead of buying all the cameras next time go to a one hour photo place and ask if you can have the empty disposable camera shells. I know for a fact that Costco One Hour Photo keeps the empty shells to be recycled. I’m pretty sure most places won’t mind giving them to you.
Plusses:
Save $13, better components(?) from Kodak and Fuji cameras, return the empty shells back to the store for recycling.a
Cons:
Have to say please and thank you, might have to explain what you want them for.

A bit of a problem I’ve ran into. I’ve wired 10 capacitors to a camera circuit board and… well I fried it. a standart AA battery wasn’t enough to charge them, so they wouldn’t even discharge. I’ve tried to hook up a 22 volt led-acid battery to it, and thats when I fried it. Is there any way to charge them up without the circuit board? I was thinking of putting up a parallel switch onto the wires going to the capacitors, so when they are charged I’d flip a switch, and the energy would go straight to the coil instead of going through the board. I s that possible as well?
