3D Printed RP2040 Powered Ring Measures CO2 #WearableWednesday
If you are worried about monitoring CO2 but are always on the go you should check out this wearable. The ring changes color to give you an instant update. Picked up by Tom’s Hardware:
While precise details on the inner workings of the project have been kept under wraps, we can infer a few things from pictures provided so far. The ring is 3D-printed, features a CO2 sensor and uses an RP2040 to interpret sensor data and trigger LEDs on a NeoPixel ring.
If you want to check out this project up close, visit the original thread on Twitter and be sure to follow Guido Burger for more updates on this clever RP2040 CO2-detecting NeoPixel Ring.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
