Tired of building the same old Arduino projects like blinking LEDs, temperature monitors, and line-following robots? Now it’s ...

[Ben] may be 15 years old, but he’s got the knack for 3D printing and artistic mechanical design. When you see his 3D-printed mechanical jellyfish lamp, we think you’ll agree. Honestly, it is hardly ...

An optocoupler tester is a small device that helps verify whether an optocoupler is functioning properly or has failed. In labs and repair work, optocouplers often fail without clear signs. They may ...

Following an in-depth interview with forpeople’s creative director James Addison, we go under the hood of a rebrand that translates the bio-electrical pulses of African trees into a living ...

But sir, it is wafer-thin. That’s how they get you! Just when you couldn’t possibly justify building another keyboard, let ...

In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

In this video I've created a device that can notify in real time about events that happen on a website. The project uses NodeMCU board and a buzzer to produce sound as alert. The board is programmed ...

A basic building block is often the key to completing an analog signal path in various applications, such as automated test equipment.

Scientists at the University of Cambridge have developed a new way to alter complex drug molecules using light rather than toxic chemicals—a discovery that could accelerate and improve how medicines ...
