This secure, AVR microcontroller-based Combination Access Switch allows you to control electrical loads or other circuits by entering a (secret) three-digit access code.

Back in 1978, Elektor Magazine wrote: “An oscilloscope can be used not only as a test instrument; with the aid of the following circuit, it can be made to generate a multitude of fascinating and attractive geometrical patterns.” Interestingly, 45 years on, this bunch of opamps

The T-962 Infrared IC Heater by Puhui is a small, low-cost and therefore popular reflow oven for soldering SMT components to a printed circuit board. The Elektor version of the T-962 corrects a few shortcomings of the original design and adds a serial port for uploading custom

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

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

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

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

Can a robot dog serve as a personal companion, delivery assistant, or even pull off a few office pranks—with guidance from ChatGPT? The experiment put AI suggestions to the test. Watch the full video .#AI #robots #robotics

Read how a simple ultrasonic sensor, a vibrating motor, and one or two microcontrollers turned into a practical upgrade for a walking frame. This ultrasonic obstacle detection module is capable of identifying objects up to four meters away.

From autonomous AI agents to multimodal systems that seamlessly blend text, image, and code, the first half of 2025 has transformed AI from experimental novelty to everyday reality. But as capabilities soar, questions about productivity gains and sustainability persist. What does
