![Add a Multicolor Filament Changer to Any 3D Printer | Open Source Solution
Clem rebuilds the 3D Chameleon MK4 from the ground up, replacing the legacy electronics with a modern ATtiny3226 controller, TMC2209 drivers, thermistor-controlled cooling, and clearer status indicators. The mechanical system stays true to the original open-source design, but the updated hardware is easier to assemble, easier to source, and designed for reliable multicolor filament changes without modifying your printer’s firmware. The full project, files, and code are available on the element14 Community: https://bit.ly/3Y66qRC

![Testing, Testing! Emergency Mint Tin Radio!
Mark builds a mint tin emergency radio using an Arduino Nano, a TEA5767 FM receiver module, a custom PCB, and a coin cell–powered microcontroller-controlled supply. The challenge was designing a compact circuit that fits into a metal mint tin while avoiding shorts, using the housing itself as an antenna, and creating a power latch system for reliable operation. The radio is programmed to lock onto a single predefined station for emergency use, with careful soldering and component placement to make the design practical and portable: https://bit.ly/3VQzlIi
