Hello,
I am making a back light for a picture frame for my son. It's going to be lit by LED's. I found this site and followed the instructions and put it together on a breadboard. I tested with 3 LED's at 12 volts and my 2N2222 is burning up almost instantly. It doesn't fail, just gets too hot to touch. Is there anything I can do to this circuit to get a cooler transistor in there?
