His newest providing, an enormous analog CO₂ meter, may well be our favourite to this point.

The brains of the operation is an Adafruit Feather Adalogger.

For the large needle, this pretty meter makes use of one of the ones fiberglass poles you mark your driveway with so you’ll be able to in finding it beneath a blanket of snow. The needle is counter-balanced with washers encased in published plastic.

As you’ll be able to see within the GIF, there is a respectable lengthen between the CO₂ blast and the needle reaction — we love to believe the CO₂ spiraling slowly throughout the nautilus like a heavy, sick wind on its method to gravely transfer the needle.
