Focus on Test & Measurement

Elektor Edition July / August

In July and August 2022, Elektor focuses on Test Measurement projects, technologies, and solutions. Elektor engineer Clemens Valens dives into oscilloscopes and offers some helpful tips and insights. In an article titled “Inexpensive Audio Measurement Station,” Alfred Rosenkränzer combines his professional specialization in measurement technology with his passion for audio. A good USB audio interface, a PC and inexpensive measurement software are enough to obtain a handy solution for measurements on hi-fi systems, do-it-yourself speakers and other equipment. The issue also features various practical projects. For instance, we present a measuring device for the mains frequency as well as one for the series resistance of capacitors. Plus, you will learn about an inductance meter that’s easy on the wallet, and much more!

Kurt, We Will Miss You!
“It came as a shock to all of us when our long-time colleague Kurt Diedrich passed away unexpectedly in April 2022. Kurt was an editor at Elektor in the eighties; since then, he has remained loyal to us as a contributor for all these decades. A geology graduate, he wrote books and articles, translated entire issues (most recently our sister magazine MagPi), and brought schematics and other drawings into the famous Elektor style. In his spare time, the music lover built analog synthesizers and picked up the guitar. Kurt, we will miss you!” — Jens Nickel (Editor in Chief, Elektor)

In this edition, Erik Jansen (Managing Director, Elektor) details Elektor’s plans for e-ffwd 2022 (electronica fast forward, the start-up platform powered by Elektor), which will culminate with a presentation at electronica 2022 in Munich, Germany in November 2022. “This year we intend to really scout out the crème de la crème of start-ups and give them a podium,” Jansen explains. “We are focused on interesting and innovative entrepreneurs with a lot of conviction and boldness. In order to find them, we are going even further in 2022.” This means Elektor is actively scouting internationally through industry collaboration and international publications to find innovative electronics-focused start-ups. A total prize pool of €150,000 in marketing exposure and one of the highly desired invitations to electronica 2024 is available for the winners. Visit www.elektormagazine.com/effwd-2022 for details.

Most modern test and measurement instruments are nothing more than a microcontroller supported by special signal-processing circuits and a nice display. The Arduino UNO board too is based on a microcontroller and features analog and digital inputs. It can therefore be used at the heart of a measurement instrument. Even if it lacks special signal processing circuits, it can be very useful in many situations where signals are not superfast or where ultrahigh precision is not required. Instead of investing in an expensive all-singing, all-dancing oscilloscope, it is often enough to write a few simple sketches, learn a few tricks and know your way around a spreadsheet. Join us for a webinar on August 11, 2022, at 16:00 CEST.
