Been thinking about the people's permacomputer, a little instant-on BASIC computer that I want to build for educational purposes. I have so far been targeting Atmel AVR chips not unlike those inside classic Arduino boards. I also have a few raspberry pi picos on hand, and I am wondering whether they would be better suited for the purpose. They are, critically, quite cheap compared to a whole AVR setup. They're 3.3V, compared to an Arduino with 5V, so perhaps back to the drawing board.
