Designed from scratch, with no UD board in its ancestry. An NE555 runs the 730 kHz main clock. A second 555 sets an adjustable duty cycle for the fixed-interrupter mode, and an LM358 comparator stage turns an audio line-in into trigger pulses for music mode. A jumper switches between the two. 74-series logic shapes the drive signals, and TC4420 gate drivers push a gate-drive transformer. It was built up from breadboard and perfboard modules on the bench (oscilloscope, bench supply and function generator all visible in the build photos) before a final PCB, silkscreened plainly "Solid State Tesla Coil Driver, By: Naman Tanwar." Published with co-authors Rajeshkumar Muthu and Rani Chinnappa Naidu in IEEE Access (2024). The full design is on GitHub: Altium project, gerbers, BOM, LTspice simulations and demo videos of the coil playing music.
