    If viewers are keen I will do a video / tutorial on how the circuit works and mention a few “tweaks” that can be made on how it operates.

    My components:

    * Infineon MOSFET N-channel 200V 13.5A TO-220 – BUZ31L H
    * Vishay 534 Series Pot with 6.34mm shaft, 50K
    * 2 x 10 k Ohm resistors
    * Arcol HS50 Al house wirewound high power resistor,1R (1 ohm) 50W – HS50 1R J
    * National Semiconductor Quad op amp,LM324N 1MHz DIP14
