I still need to write up a full blog post about my latest ESP32 adventures, but suffice it say they've consisted of indoor air quality sensors, RGB LED modules, teeeeensy little ESP32 boards, and my very first 3D-printed things!
From top to bottom, the LEDs show the outdoor dew point, outdoor air quality, and indoor air quality (or office air quality for the other one), where blue is good and it goes through the spectrum to red is bad, and on the left you can see the back side of the holder where the ESP32 lives. I used Tinkercad to design and print the holders, and got a friend to actually print them out. The first ones didn't QUITE fit the LED boards so I had to go back and slightly tweak them, and the second round was a great success. I airbrushed them black because the resin he used was this weird pale almost-flesh colour that looked terrible, haha.
