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 ...

NCERT Class 12 Physics Chapter 14 Semiconductor Electronics Materials Devices and Simple Circuits Solutions: With board exams approaching, students need to review their syllabus and begin practising ...

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 ...

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 ...
