I just finished a new project, which is called Always-On. This project is a simple bidirectional bridge between the mains-voltage installation and an Adafruit Feather board as a controller. The idea is to have a device integrated into the electric installation. It works as a smart light switch, monitors power lines or works as a…

A New Modular CMake Based Toolchain for Feather M0 HAL
In the past months, I developed firmware for a few Adafruit Feather M0 based projects. The reason why I use the Adafruit Feather platform, instead of using an MCU directly, is for modularity. By using a board on sockets, it can be replaced at any later time with a more powerful one – or by…
No Success with First Long Term Measurement
The first long term measurement I made, to test the behaviour of the sensor over a longer time range was a failure. After the five days with the device introduced in this post, the readings made absolute no sense. The sensor was not moved in the flower pot and the plant was once watered at…
Plant Watering Sensor – Long Term Logging
To gather more long-term measurements for the capacitive method I use for my plant watering sensor, I created this small logging device. As you can see, it uses one of the plant watering sensor prototypes for the measurements. Instead of using the ATtiny13A on the board, it passes the oscillator signal directly to the microprocessor…
