Last year, we published a high-quality, variable-frequency audio notch filter. To complete a typical test lab setup for measuring audio equipment performance, this article introduces a high-performance audio frequency generator with continuously adjustable output frequency control. The key component in both these designs is something called a State Variable Filter. https://www.elektormagazine.com/magazine/elektor-429/63931

As sensing technologies continue to evolve, they are quietly shaping how robots perceive and interact with their environment. This article looks into a range of LiDAR sensors, and depth cameras that are commonly found across robotics projects — from research and education to more advanced applications. It also touches on software ecosystems, typical use cases, and a few higher-end options that hint at what's possible as these tools become more widely adopted. https://www.elektormagazine.com/magazine/elektor-429/63947

In this article, we explore two hands-on projects that demonstrate how devices can communicate wirelessly. First, we’ll set up a TCP connection between a BeagleY-AI board and an Android smartphone to send text messages. Then, we’ll explore controlling an LED connected to BeagleY-AI from a smartphone using UDP. These projects will give you a practical look at how wireless communication works in everyday tech! https://www.elektormagazine.com/magazine/elektor-429/63938

You must know the feeling: you’re watching a great movie and all of a sudden a commercial comes blasting into the room. Your instinctive response is to turn down the sound or press the mute button. This PIC-based circuit can sense vibration from a knock and send an IR signal to silence a TV. No remote required! https://www.elektormagazine.com/news/circuit-the-mini-mute-commercial-killer

This article details the development of a real-time automotive sensor dashboard by using an ELM327 OBD2 module and an ESP32-S3 touch display. The dashboard shows essential sensor data — including coolant temperature, battery voltage, oxygen sensor voltage, fuel economy, and engine load — retrieved directly from the vehicle’s ECU, offering instant, reliable diagnostics, and opportunities for future enhancements. https://www.elektormagazine.com/articles/obd2-sensor-dashboard

In this article — the first of a series — we are exploring the possibility of making a measuring device for static electrical fields, which thereby could also allow a completely contactless measurement of DC potentials of objects. As sensor for the field, a vibrating membrane is used. In the second installment, the amplitude of the membrane’s vibration will be assessed, with the help of a laser-based makeshift vibrometer. https://www.elektormagazine.com/magazine/elektor-429/63929
