Bluetooth Volume Knob
Completed
Originally an excuse to play with Bluetooth Low Energy and wireless charging, this simple project combines an nRF51822 module with a slick maple base, 3D-printed LED ring, and an anodized aluminum knob.
Features
- nRF51822 Bluetooth Low Energy (BLE) module
- HID Keyboard emulation
- High quality quadrature encoder with click function
- Custom PCB with 3D rendering (Altium Designer)
- Wireless charging
Introduction
In early 2017, I purchased several new tools to start basic woodworking projects. I also decided that I wanted to start documenting projects along with high fidelity 3D models and renderings. The resulting project was a very simple volume knob that served as an educational tool in learning both new software and woodworking tools while providing an opportunity to design with space constraints.
