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 ...

Discover how to build a simple wireless power transfer system at home using readily available components like enameled copper ...

In the past few years there have been countless toys that claim to be STEM-focused (Science, Technology, Engineering and Math) but few have done as good a job at introducing kids to concepts like ...

How do I learn circuit building and electronics on my Mac? If you want to learn about basic electronic components and how to build simple circuits, using your Mac as a learning resource, then you’ve ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

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

One of the problems encountered thus far with 3D-printing circuits with conductive filament is that it doesn’t really bond to anything, let alone solder, so how does one use it? [mikey77] wrote an ...

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 ...

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 ...
