I had no idea this was coming.
I had finished writing a huge tutorial on how to build a homemade air quality monitor here. https://www.jaredwolff.com/homemade-indoor-air-quality-sensor/
I felt though that I could build a circuit board that did the same thing in a smaller package. So, for the first time in my life, I created a sales page and encouraged folks to check it out.
Building something yourself and seeing someone buy it feels amazing. Now it's time to get more people to do the same!
