How do i make a capacitor charger circuit? Answered
I am talking about one for in a coilgun. i had a old (very old, 1.3mp) samsung digimax 101 digital camera, I decided that since i have moved on it was time to take it apart for the rich insides.
I knew what to look for, so i found it; the transformer for the capacitor charging circuit and the big cap for it. I unsoldered the transformer piece, cut the wires from the cap (it was not mounted on the board), and unsoldered the flash which had not 2 but 3 wires coming from it. one was yellow, one was green, and one was black and was attached to the deflector behind the flash. the black wire was connected to a small black piece that looked a lot like the charger transformer but only had two active pins instead of four. im not sure what it is for, i think it is a self resetting fuse, incase the camera short cicuits, but im not sure. any insight on that would also be helpful.
Back onto the subject, i would like to know what i need (other than the yellow transformer piece) to make the charger circuit. I have heard there was a transistor, would it be NPN or PNP?
there was also a diode, i am guessing one of the black ones, but is there anything else? i have those three things if that is all i need, but how do i solder it all together?
thanks in advance,
PS: the yellow transformer has only 4 pins that actually do anything, one is between two on one side and is only for support. either that or i accidentaly broke it.
