COVID-19-safe controller: switch lamps and other devices on and off by using gestures instead of pressing buttons (on a remote control).

It’s not easy to find a small, high-quality monitor that is conveniently portable – the options are fairly limited. The Joy-View 13 makes the choice a lot easier, and thanks to the presence of both HDMI and USB C ports, it can be connected to virtually all modern devices. We tested this small 13-inch monitor with several types of computers.

Because it is almost impossible to work on the Raspberry Pi, or, for that matter, on Linux in general, without ever needing to enter commands in a terminal, here is a list of frequently used Bash commands.

The price of the 2GB Raspberry Pi 4 has dropped. And just in time for RPi's eighth birthday. Get yours now!

An experimenting set for the Raspberry Pi that, after opening, resembles the briefcase used (in movies) by not-so-smart presidents to launch their arsenal of rockets? That demands closer inspection!

There are other books about learning to program in Python on the Raspberry Pi, but Dogan Ibrahim aims this book at a specific target audience: electronics engineers.

Sensors are a worthwhile topic to write about: They bring electronics projects in contact with the real world and facilitate all kinds of practical applications. Dogan Ibrahim describes more than 40 projects in this comprehensive book.

With the compliments of the Elektor Labs and Editorial teams, and our best wishes for the new year, here comes another previously unpublished article that's free to download by all registered Elektor e-zine readers. "Free Fresh Articles" are published at two-weekly intervals in the Elektor e-zine, alternating with "Free Back Articles". This time we have a Graphic User Interface (GUI) with touch control that’s remarkable for two things: First, it’s one and the same piece of hardware running happily on at least three popular microcontroller platforms: ESP32, ESP8266, and Raspberry Pi. Second, it employs elements from the LittlevGL library which comes with an MIT licence and produces code for many 16-, 32- and 64-bit microcontrollers.

For your IoT experiments, if you want to connect many wireless sensors to your home automation system for example, you need a long range wireless network with low price. And a gateway nearby. Try the Dragino LoRa/GPS_HAT module together with a RPi. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising consumption... and costs !

Building a small weather station to take measurements of the main environmental variables could hardly be simpler; grab an off-the-shelf microcontroller board and plug in an expansion board with all the necessary sensors on-board. Choosing an Raspberry Pi (RPi) significantly simplifies the design, add a HAT like the Enviro+ from Pimoroni and you already have all the sensors you need to get the job done.
