Overview
Use these prints to build a wireless Bluetooth Low Energy adapter for a Wii Nunchuck controller, which can be used to remotely control electronics projects.
Special instructions:
I printed the top in white PLA to allow the light from the LEDs to show through the lid.
Parts:
- Feather nRF52840 Express
- Wii Nunchuck adapter breakout
- Mini on/off push-button switch
- 400 mAh Li-Po rechargeable battery
- Black 2.5mm nylon standoff screw kit
- 4 M2.5 6mm screws
- 4 M2.5 6mm male-to-female hex standoffs
- 8 M2.5 hex nuts
- Wii Nunchuck controller
Building instructions:
- Solder wires from the Wii nunchuck breakout's VIN, SDA, and SCL pins to the 3V, SDA, and SCL pins on the Feather, respectively.
- Solder a wire to one lead from the on/off switch. Solder the other end to the EN pin of the Feather.
- Solder a wire to the GND pin of the Wii nunchuck breakout, and another to the remaining lead on the on/off button. Splice the two wires together, and then solder the other end of the spliced wire to the GND pin of the Feather.
- Use 4 screws and 4 hex nuts to fasten the Wii nunchuck breakout to the 3D printed case.
- Plug the battery into the Feather.
- Use 4 male-to-female hex standoffs and 4 hex nuts to fasten the Feather to the case. Position the battery so that it sits underneath the Feather.
- Slide in the button mount 3D printed piece into the slots on the case (it's a tight fit).
- Position the on/off button so that it fits into the hole in the top of the 3D printed case, and then snap the top of the case to the bottom, making sure the side of the lid the on/off button is placed over the button mount geometry.
- Plug the Wii Nunchuck controller into the adapter.
- Once assembled, you can use Arduino, CircuitPython, or the Nordic SDK to program the adapter to meet your needs. In my case, I'm currently using it to control these nifty LED glasses from Adafruit.
