this is my first post on this forum so i hope im posting the right place.
i have build This and it works great, for a while...
when i use it the spark keeps getting shorter and shorter.
i think the 555 or the transistor is getting fried by the inductive kickback from the ignition coil. if i touch the transistor while it's on i can see and feel very small sparks.
if i change the 555 it goes back to full spark lenght, then the spark gets shorter and shorter.
can anyone tell me what i can do about this problem?
it's getting abit expensive with all those 555's i have to buy
