Basic Idea. Designed with the Raspberry Pi Zero in mind. Contains logic. Logic High means main power is active. Logic Low means main power is inactive. Write code to watch for logic Low, and issue a shutdown command (after logic is Low for X amount of time), which hopefully prevents data corruption.
Not sure if this is feasible in real life. Still needs lots of work. Also, this my first time building a buck converter, and I'm sure there is plenty to fix, and things I have overlooked. I couldn't get the Buck converter to work with a FET. At the end of the day, it was just fun to build. Help me make it better :D
