Building an ignition

Yesterday afternoon a friend and I build a sort of portable ignition for a “bigger project” which I can’t mention for the moment.
First we had to find a suitable coil, so we drove to 6 garages. At least we found a (smaller) coil from a mower in a garden shop. Based on an ignition scheme from a car combined with an NE555 timer chip and a 9V battery we made the first design. We succeeded in making some little blue sparks. Not suitable for a good ignition. After a while (and blowing up an NE555) we found that the transistor which we used was to light. After some optimalisation we came to a nice result -> sparks with a length of 3mm.
Isn’t it time to build a bigger Tesla Coil? 🙂
