Raspberry Pi Zero 2 W Drives Wii Nunchuck Wireless Mouse
Adrian Papineau’s Raspberry Pi Zero 2 W-powered Wii nunchuck wireless mouse; a creation he calls the PiChuck. It’s battery-powered; and you can take it on the go for use as an input device for his wearable display glasses.
Papineau first created this project a few years ago but has been recently upgraded to use the Raspberry Pi Zero 2 W. According to Papineau, the joystick moves the cursor around while the buttons function as mouse clicks. As a result, it makes it possible for him to browse the internet and check the news while out and about on walks.
Papineau describes himself as a mechanical engineering tech and a general tech hobbyist. His experience shines in this project and his history of work covering things from custom mechanical keyboards; to various 3D-printed designs available over at Thingiverse. This project combines his love of microelectronics and 3D printing; with a custom shell made to fit the Pi Zero inside of a Wii nunchuck.

A fair bit of hardware is required to get this project off the ground; including a spare Wii nunchuck, a Raspberry Pi Zero 2 W; and a 3D printer for creating the mounting frame inside the hand grip. In addition, it needs an Adafruit Powerboost 1000 charger and a battery; in this case, a 750mAH 3.7V Holy Stone Model 752555, to make everything mobile. Finally, it uses an HDMI ribbon cable assembly to connect the Pi Zero nunchuck to his Vufine display.
