help
hey
i am also looking for a spark generator, tried using a relay at first to switch the current on/off but soon realised it was sparking inside the relay so no spark was being produced.
This is where i found the schematic for the 555 circuit (above) but just a couple of questions, would the 12v/6A supply kill the 555? and there is no protection for the transistor?
I am going to start building the circuit but i would just like to know what changes should be made to the circuit as i am fairly new to electronics!
Thanks
Kane
