Hey, I currently got into the mood to build a coil gun :twisted:. I've been thinking of buying some photo flash capacitors about 15, 150uF caps. Wiring them in parallel, and using the charger circuit from a throw-away camera. The barrel will probably be a disassembled pen with magnet wire wrapped around it.
I was thinking about using these capacitors:

Please if you know of better ones, please post.
Some questions I have are, where can I buy photo capacitors cheaply? How do I calculate the amount of energy the capacitors will release, and be sure the wire can handle the current? Also, what can I build to charge the capacitors effciently.
I'm open to suggestions, please share your experiences and ideas.
Thanks!![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Note: I only want to build a Single Stage coil gun, I will be happy if it can accelerate a projectile about 35 feet
