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 ...

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 ...

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 ...

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 ...

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 improved one-BJT current-limiting supply is not much different than the primitive circuit, though its one additional resistor does change the circuit behavior. The improved circuit is shown below.
