This is the Crankpad. An unofficial wired controller made specially for the Playdate Simulator. It's designed for game developers that don't have the console yet but would like to build games for the Playdate console.

While it doesn't compare to the real device, it gives you a nice idea of the use of the crank in gameplay (using the simulator).
These are the electronic parts I used:
