Yes, I just posted something on a flyback. I was interested in that, until I saw this. It got me interested in ignition coils, so I got one new from the autoparts store for $20 (USD). I looked on the site, for the schematic, and realized that I didn't know what the rectangle was. Is it a resistor? I'm new to electronics, what size resistor do I need (if it even is a resistor)?
What about the capacitor? I have a 100uf 200v electrolytic one, will that work?
Also, part of the core is not in the coil, it's square shaped, could I rig it to work like this flyback circuit?Or this one? (simple driver circuit)?
Sorry about the never ending beginner electronics questions, I just really don't have anyone else to ask.
