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 ...

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

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

Over the last couple of decades the use of rechargeable batteries has grown enormously, and for most common applications there are ASICs[1] which control battery management with very little additional ...

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 ...
