anyone know of schematic of a basic charging circuit for a coil gun? I found a charging circuit for a kodak disposable camera, but theres a few things I dont recognize in the image. And I wanted to make my own, anyways, so that I can shrink it. make it much smaller using SMDs.

Hope someone can help. wink

btw heres the image of the charging circuit I found. Kflashm

[Edit: Go here Link2 to learn how to post pictures.]

I dont think you should be asking for schematics.

What about the kodak schematic dont you understand?

im sorry but it is a pain in the butt to do draw one yourself if you are not an electrical engineer.
almost anybody who can read the schematic can put one together, and learn from it.
its a learning experiance.

im sorry about my little rant, try taking a look at a boost converter

yes 555 boost converters are quite cool. take a search on google for them and you will come up with results and schems.

Also a good place to start is of course Steve Wards page
Link2
He has a nice boost converter there with schems :D
Good Luck,
Mike

First of all, I didnt put that schematic together, I found it. Second, theres a part called IL1-NE2X. I dont have a clue what that is. Third the goal of me finding out, is so that I can concentrate my efforts on the coil gun im building, not the charging circuit that goes for it. Sorry If I seem a little blunt... cheesey

The circuit you posted is much more complicated than the one you actually need, for example you wont have a use for a trigger transformer... Just have a look at the boost converter three threads down, something like that is all you need.
