My idea for this project is quite simple in theory but will be a challange to build. Pretty much, you insert a coin and the computer turns on, giving you time to play a game or do emails or whatever the user wishes. How it would work is using the raspberry Pi as the main computer and using one of the Pi touchscreens to control it. It can enforce the time limit without having to shut off the whole Pi and possibly damaging it, by, simply turning off the screen, making it so you can't continue using it without another coin.
