  1. Last year I worked on an ESP32-powered air quality monitor device with audio/visual alerts, but couldn't finish it due to RSI. Now I finally got around to documenting the last bits and uploading pre-built firmware binaries.

  2. I wasn't satisfied with #Sensirion's #USB powered #CO2 traffic light due to its hardcoded thresholds, so I built my own using a #RaspberryPiZero with solderless #ZeroDongle, #I2C #BreakoutGarden Mini #pHAT, Sensirion #SCD41 CO₂ sensor breakout and the #Pimoroni #LEDShim. All parts available at shop.pimoroni.com except for the Pi which is sold out.

    The code behind it is based on two library examples by @gadgetoid and available at github.com/xtaran/co2-led-mete under the #MITLicense.
