I made this to put in a toy gun, it makes a clicking sound fine but i noticed it can also make a LED flash. does any 1 no how to get rid of the transformer?
forgive my diagram im not very good at this stuff yet.
I've seen this circuit, and I tried myself replacing the transformer with 2 470ohm resistors, but it failed to work. I asked my college lecturer why, and he said that the transformer acts a an inductor. You can buy inductors, but they are probably just as big and expensive as the transformer. You can't easily replace it in a word.
You might want to try a 555 flasher if you really can't live with this transformer, or if you need the circuit to be compact.
