Hey everybody!
I'm working on a Singing Tesla Coil for a 4-H electricity project and I just finished my first draft of the circuitry. I was wondering if anyone would be kind enough to give me some tips or point out any glaring mistakes I made. Thanks for your help.
Relevant info: the voltage regulator is a LM317, the Op-Amp is a LM741, the PWM is a UC28025, and the MOSFETs are FDA20N50F's, the 18.5V power source is an old laptop power supply, and the audio is coming from an old Walkman CD player. In addition, I would really like to avoid using GDTs. They're prohibitively expensive and difficult to make. And if I need them, it means I fried the MOSFETs which are the majority of the expense of this project, so I don't really care about cost after those fry.
