In the last few days, I get hands on an interesting Raspberry PI touchscreen display. I was wishing to use it to test some projects like a retro gaming console and/or a home control display, but using it I thought that it is enough interesting for being worth a dedicated post. The display is the […]

In this tutorial, I’m going to show you how to install Transmission client on a headless Raspberry PI to get files downloaded from a low power consumption computer and avoiding to keep other power-hungry PCs on. Even if the streaming services have changed a bit the roles, internet downloads have evolved during the years to

In this tutorial, I’m going to show you how to wire, calibrate (X / Y axes) and use an HMC5883L device, also known as a magnetometer, with Raspberry PI Pico using MicroPython. Many projects (like robotic ones) need to get info about spacial position and direction. In this sense, one of the most useful devices
In this tutorial, I’m going to show you how to connect, configure and use a Raspberry PI Pico Ethernet Port with WIZnet Ethernet HAT. We’ll use CircuitPython to connect the interface as, actually, the MicroPython libraries are under development. Raspberry PI Pico works greatly to keep sensors measurements, combining/analyzing them and delivering data to external
