There’s probably some maths involved but trial and error would be good enough. Even the best coilguns have efficiencies in the single percentage points. And something like a ~40V TVS (transil 1,5KE39A ) across the MOSFET instead of “flyback anything” will not be enought? Last Updated: October 8, 2020 Make sure your gun isn’t aimed at any living thing since it will shoot quickly. Looks like a datasheet reading misunderstanding – the 20v he read is for the absolute maximum gate voltage (not the trigger level), the Vgs(threshold) is marked as 2 to 4v (okay, for a low Vds but it should be low as FETs have low resistance). Try An MSDOS One. I liked his video editing, as for the rest of it….
