This looks great. However, how do you boot and shut it down? I am looking for a way of fitting a on/off switch that gracefully shuts down the Pi. I’ve looked at Witty and the Sleepy Pi but I cant figure out how I can get them to work.
For gracefully shutting down and turning on the RPi, look at Pimoroni’s OnOffShim. It connects to the GPIO header using the first six pairs of pins starting at Pin 1. It has a small switch on the edge of the shim, but also provides pads for connecting an external switch. It works quite nicely.
