Quick Question: IF vs Flyback Transformer

Question

I'm currently trying to build a novelty shocker from instructables, but I don't have the 5 pin Flyback transformer. I have a 5 pin IF Transformer from an old radio, can that be used instead?

Hi Rovert, No the IF transformer will not have the proper primary to secondary turns ratio to make the circuit work. When I was a young delinquent I used to hollow out books and put a small buzzer in series with some batteries and the secondary of a 6.3 volt transformer. The primary would then have about 100 volts AC accentuated with a lot of spikes that were quite a bit higher. I would make a fancy cover for the book laced with tin foil and insulated top to bottom. On a small insulated portion of the cover I had a door bell button that I could push while fully insulated from the rest of the book cover. At one point I stood up in Math class and told our new, fresh out of the university, math teacher that on behalf of myself and the rest of the students I had a gift for him. I held out the book and as soon as he had a grip on it I pushed the button and lit him up. It was hilarious, but he was a really big guy and I had to run like heck to stay ahead of him so he could come to his senses and not hit me. Ah the good old days. John
