This is a simple but effective little device that we keep in our house plants. All it does is measure the soil moisture and turn on a red light when it sees that the soil is too dry. They need to be calibrated for every individual plant but after that, they just work for as long as the batteries last.

Eventually, I plan to build this into a system to automatically water the plants too.

When I moved to Huntsville I decided that I wanted to make an audio stand that fit my needs exactly. I’m not an excellent woodworker but this wasn’t a very complicated build.

It looks excellent in my living room.
