For my build, I used the $50 HQ Camera Mod, a Raspberry Pi 4 computer, a USB-C portable 10,000mAh charger, a 3.5-inch touchscreen, jumper wires, a mini push button switch, the body of a Ninoka NK ...

A clever modder paired a Nintendo Switch with a Raspberry Pi 4 to stream games like Pokemon Sword.

There's a microcontroller inside that connects the physical button inputs to the Pi, a 10,000mAh battery that charges via MicroUSB, and even LED lights to show the volume and battery levels.

Input from the user is sent over the Pi’s UART to the Trinket, which itself is running a firmware specifically developed for mimicking Nintendo Switch controllers.

Both the Raspberry Pi Pimoroni OnOff SHIM and Pimoroni Button SHIM with 5 x tactile, right-angle push buttons are priced at $6.95 and both are in stock as of the current time.

A hardware hacker has solved a problem of powering on 16 Mac minis in a rack, by using a Raspberry Pi to physically press each power switch.
