Building simple circuits with copper tape, LED bulbs, resistors, and watch batteries is not as simple as you might think. Notre Dame Elementary School STEM students are putting the engineering design ...

One of the coolest things any sound system can have is some kind of musical visualization. Thumping level meters that pump with the volume are a great example, and were particularly popular in the ...

The cost of 3D printing has come down dramatically to the point you can set up a small printer in your home. Those printers only spit out little plastic baubles, though. The cutting edge of 3D ...

Introduction to electronic components and circuit building Guides for beginners and advanced users Projects involving the new AI Kit, camera & vision, and private cloud server Step-by-step ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

In the ongoing drive to make circuitry ever smaller and more powerful, researchers in Canada have taken things to a very small extreme. They devised a method for turning individual silicon atoms into ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

I recently published a Design Idea (DI) showing some very simple circuits for PWM programming of standard regulator chips, both linear and switching, “Revisited: Three discretes suffice to interface ...
