Thread: Ignition coils for small engines

18/01/2010 17:43:20

Hi all! Happy New Year!

I have run a standard car ignition coil by charging the capacitor to 150 - 200 volts and discharging it through the coil. this removes the need for standing current of 3amps from the battery. I'm trying to see if i can run it from scrap disposable camera flash units, as these run on 1.5volt batteries. WATCH THE CAPACITOR IN THESE UNITS as they pack a WALLOP!!!

I'm working on a high voltage (100 - 200 volt ) supply for the capacitor to discharge into the coil, ultimately to be derived from redundant flash circuits in disposable cameras.

So far i've had sparks of 10 - 20 kv from a 150 volt supply and a car ignition coil.

Those wishing to investigate these circuits MUST BE CAREFUL as DANGEROUS VOLTAGES are generated from a 1.5 volt battery!!
