Hello windozeuser,
Insead of spending a lot of cash for some photoflash caps, you should just got to a few places and get them for free like Digitan said, I did this and got about 20 from walmart in one trip. (Don't get shocked when taking them out of the cameras, some are charged when you get them (PAINFUL)!
I went to wallmart today and asked the lady in the photo department "Do you resell or give away throw-away cameras you develop" Shes like "NO, We recycle our throw-away cameras, it's not in my policy to give you any"
How did you guys get them?
Btw, I bought 40 feet of 22 gauge magnet wire from radioShack. Is there a guide on how to construct coils around say a certain diameter tubing. Then find out the strength of the flux lines inside the tubing.
Thanks a lot

Somebody on one of these posts is claiming a coil current of 500A through his little wires with alligator clips!
I think the little wire would jump farther than the projectile if it had as much as 10A through it.
Wouldn't the entire current just be a huge spike that only last a couple of mS's? Would that be enough to heat the coils up and cause them to short out and arc? I guess it would depend on the inductance of the coil with and without the ferrous projectile, and also the resistance of the coil?
But as I see the power value of a theoretical 400V setup...
P= 500A * 400V = 200,000 Watts o.o
How do you calculate the current capacity of magnet wire?

Have you tred eBay, lately i've seen some pretty powerfull caps on ebay , they are used for car audio sound systems..
two or three of the single Farad versions in parallel , could probably start your car, or shoot a neo magnet through the wall :twisted: ..
Or knock you dead cold in less than a second heh heh, but seriously thanks for the advice I'm gonna search ebay right now
