Someone Please Help!
I have been watching dozens of videos on creating a mini Tesla Coil. Trying to help/teach 12yr old for up coming science project.
For the life of me I just cant get it to function. I have tried many setups regarding the resistor, transistor, primary and 2ndary coil. Had TIP31 and 47K with 9v, that didn't work.
Currently have approx. 610 winds on 2ndary (on 2" pvc). Have 7 on primary "in same direction as 2ndary", switched it from 3 to 7 to see if that works. Using 2N2222A and 10k. Using 12v (8 AA battery setup)
I found an approx. 8.3 to 8.5 fluctuation in current between main switch and Collector. Found 9.4 between Collector and Emitter. Transistor was slightly hot to touch, which is probably the plateau current not switching fast enough.
What am I missing, the electrically challenged person that I am? Is it the coil setup? The input voltage? I am clueless!
