Circuit not working, transistor heating up?
Some differences in my circuit:
1- I got my transformer from an LED bulb and not a camera.
2-I'm feeding it 3v for testing.
3-The NPN transistor I used is 2N3904.
4-Im using 2 100 ohm resistors in series instead of one 220 ohm.
5-I didnt attach a potentiometer,
6-I couldnt find a capacitor like that so I used a polyster 400v 473J capacitor.
7-My diode is not a schottkey one but a 1N4007 diode.
I double checked al my connections and there are no shorts.
