I designed two Tesla transformers, one small and the other medium in size. The high-voltage circuit is powered by a 555 driven MOSFET and a flyback transformer. Please check it out. How can I improve the spark length for these designs?
An LC oscillator is driven by pulses which are generated by a 555 IC based oscillator. LC oscillator is built around 2SC2078 transistor. The circuit generates about 800V pulsed sinusoidal waveform.
Here is a simple circuit based on 555 IC that generates a pulsed magnetic field. You may use this field for pulsed magnetic field therapy.
