My first flyback high voltage generator

Thu, 07/18/2024 - 06:18

I recently made a 555 flyback high voltage generator. It uses a 555 timer whose output goes into a BJT to drive a mosfet which switches current to my primary coil (8 turns).

A piece of history (50 bytes of magnetic memory)

Someone today showed me this and I wanted to share it somewhere. Those are 50 bytes of memory and you can count every single bit! My mind blew away when he took this out of a box. I don't know if it's the right place tho 😬

I’ve always had a makeshift workbench all my life, finally own a house with space that is just mine to do what I want with.

I find the white too bright. I think I am stuck using a permanent marker instead. I believe that is 4,470 ohms.
