Another add-on board for the Arduino Uno and compatibles. It is equipped with a u-blox GPS chip. Additionally, it has a slot for a µSD card, making it suitable as a GPS logger. The current version 1.0 has already been superseded by version 2. The new version is due to the current chip shortage…

I've had the Zumo for a few years now and just rediscovered it in a box. So I thought it would be nice to write a bit about it. The Zumo is a small mobile platform onto which you can directly plug an Arduino Uno or Leonardo. It has two motors and a few sensors…

I've just connected a node to GPS and was looking for some great projects when I found this little beauty. The T-Beam from Lilygo has everything to make a location hunter happy. In addition to GPS, it also has a LoRa chip and a slot for an industrial battery. What more could you ask for.

Neatly packaged in a silicone wristband, this is the smallest version of the ESP32 that I know of. The ESP itself does not have its own programmer. However, there is a kit that contains the wristband and a programmer. Once initialised, the wristband can be updated via OTA.

As the name suggests, acceleration sensors measure the acceleration of a body, for example a car. Modern sensors measure acceleration in all three dimensions (X, Y, Z, direction). The speed of a body can be calculated from the acceleration and thus, with limitations (prone to errors), a position can be determined. Uses: aircraft construction, drones and similar, navigation, automotive industry, smartphones, satellites. Functionality: The…

An electronic compass determines the direction of north, similar to a magnetic compass. Most electronic compasses do this not only in the X/Y direction but also three-dimensionally in the X/Z and Y/Z directions. Uses: Aircraft construction, drones and similar; Navigation; Automotive industry; Smartphones; Satellites. How it works: An electronic compass is also called a magnetometer. It is based on the Hall effect. When a current-carrying...

I wanted to understand what a gyroscope can do, what it does, and where it helps. Here are my collected findings. A traditional gyroscope measures an object's orientation in space, using a rotating „inertial“ mass. Modern electronic gyroscopes work on a different principle, for example, with two piezo elements. However, they fulfil the same purpose. Applications include aircraft construction, drones...
