I was thinking of doing some thing similar to this. https://sound-au.com/appnotes/an003.htm But with a FET and a more symmetrical drive circuit such as an NCS2250 comparator capacitively coupled to the FET. So I can perhaps make it switch faster and more efficiently and with a smaller inductor. I'm aware that this might sound crazy but it's just for fun and no-one will die if it doesn't work. Since the parts aren't very expensive in small quantities I might get a board made if a simulation says it has a chance of working. It will be powered from a 12V lead acid battery. > >
