MORE ABOUT Raspberry Pi

Some people need a thousand words to say something simple and still you have no clue what they’re on about. Others manage to explain a complicated thing in only a few words. This project is probably the project with the shortest description at Elektor Labs, but then again, why use many words when it is all about images? True, there are some illustrations too.

Among the many HAT accessories available for the Raspberry Pi, the Uninterruptable Power Supply aptly called PiJuice is a remarkable one. By lifting fundamental limitations, the PiJuice is a very user friendly way to increase the performance of your Pi applications. It allows the use of your Raspberry Pi far from any power adapter, making it more portable than ever.

VGA & audio interface for Raspberry Pi Zéro & 2,3,B+

Dragino is a manufacturer of IoT hardware, specialised in Linux IoT/VOIP, Arduino Yùn add-on boards and LoRa modules and gateways. One of their latest products is the LSN50 long-range LoRa sensor node, designed for outdoor use.

A Raspberry Pi plus a homebrew HAT with driver software and a custom graphical user interface created especially for this application combine to make a unique FM radio that is not only eye-catching but a fascinating learning experience, thanks to extensively detailed documentation. Nobody can fail to learn something new from this wide-ranging project!

Inspiring people, that is what we try to do here at Elektor. It doesn’t always work, but when it happens, and we hear about it, we feel that warm glow of happiness grow inside our bodies; a glow quite similar to the one that appears when drinking mulled wine (a.k.a glühwein) in December (or any other alcoholic beverage any time of the year). This week’s project combines inspiration & creativity, Raspberry Pi and mulled wine into an original Christmas decoration.

Pixy2 is an artificial vision sensor for rapid recognition of moving shapes and colours. It follows objects at a rate of 60 images per second and has algorithms for recognition of shapes and colours. To better follow moving objects, it may be mounted (as an option) on a pan-tilt support, and control the vertical and horizontal movements itself.

In an interview with Jan Buiting, Eben Upton explains: “If you can make a device that will withstand a child’s bedroom, it will certainly withstand a factory!” […]. When those who have bought their first RPi for their own edification, at home, then taking it into their professional lives, they have to explain to their colleagues that this board, seen as a toy, is more reliable than a lot of devices that claim to be industrial.”

The new Flowcode 8 offers considerably more features that just scream to be tried out. Especially the addition of the new programming modes and working with C code and flowcharts is very impressive. The added conveniences make working with the code much easier in practice.

What do ships, factories and security services have in common? Several different and incompatible communication systems to control and secure one site. Indeed, VHF radios, telephones, intercom systems and more are all used together to communicate with the different services, rooms and departments in a building or on a site. Pollux provides a single front-end for all these communication systems.
