Hi, I'm working on a AL coin or AL disc flipper kind of design I found a while ago. Here is the video:
Instead of working like a gun, this just simply flip the coin into the air, and that is all I need. From the video, it looks like only one disposable camera capacitor was used. However I was not able to reproduce the result with the same setup (base on what I see in the video since the video is lack of some detail). Assume he just use the camera as what normally do in a simple coil gun, than the only part I'm not sure about my setup will be my coil. I'm have tried few coil design; flat one layer disc coil, coil with metal center, and even try to wind the coil messy like in the video. Can anyone give me a hand here on what I might did wrong? And what's the best way to wind the coil to enable it to flip the AL disc (2cm Diameter, 1g, hopefully can lift up to 10g) high? ( I'm using 22, 26, or 30 gauge magnetic wire, will thicker the better? ) Also, will it help if I use washer type AL disc (with hole in the middle)? Any help will be appreciated.

ok here is a short video i made, ther is a big magnet, the veiwing film and disk lanching sorry for the lack of sound i was tired and did'nt feel like narrating. here is a few pics of the guts of it the large switch is to use the terminals on the side.
here is the coil, it did look better when i had a clear CD over it but that brook off so duct tape will do

that little metal ring is AL but it was just a spacer, umm i don't know if a iron metals will help vary much the pulse time is too quick i think. most non-ferris metals will lanch but AL and CU work the best, the gauge is i think is about 12 or 14??? i will have to check, voltage is what ever the disposible camra chager puts out i think 300-400V, the coil is 2 layers 20 each so about 40 turns. this was a demo device i bult for a science project back in high school that i used a bigger varible disk lancher.
