MORE ABOUT Raspberry Pi

Google has, with Coral, launched a new platform of hardware and software tools that lets you develop neural networks locally and without using the cloud.

Mr. Beekhuyzen talks here of his experience, as an expert, with the production of quality digital audio with the S/PDIF DigiOne audio card, a Raspberry Pi HAT offered by the manufacturer Allo. His critique is very well written, very informative and delivered in an intelligible fashion. Another good reason to listen until the end, and appreciate it: he does not forget to put his appreciation in context.

Working with a Raspberry Pi is all fun and games, until electrostatic discharge or a high voltage blows up the GPIO port. Fortunately, Elektor offers a simple, affordable solution — the Raspberry Pi Buffer Board, which you can purchase on GroupGets for only $22 (~ €19.32) if you join the group buy by Saturday, February 9, 2019.

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.

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.
