Simple products are often less exciting than complex, high-tech ones, but provide an opportunity to learn about smart and efficient design. Robotwist is an example of a product that understands ...

The PCB holder uses 3D-printed parts, M5 hardware, a length of 2020 aluminum extrusion, and one spring to create a handy and adjustable design that accommodates a variety of PCB sizes and shapes.

These are the best free PCB (Printed Circuit Boards) Design Software for Windows 11/10 PC users to create, analyze, and study circuits.

The simple circuit design in lets you measure all components of a current flowing in a dc servo motor. The rectified output of the circuit uses ground as a reference, so you can measure the output by ...

This design shows how a piezoelectric transducer's acoustic output can be increased while minimizing the parts count and cost.

After more than 20 years since its first appearance, author W. Stephen Woodward presents an updated version of his classic Idea for Design article on thermoelectric coolers, including ...
