In a world filled with high-tech robotics kits and programmable gadgets, one artist decided ...

Chaos Theory has been an important pursuit of physicists and mathematicians since it was brought to the forefront as a distinct phenomenon in the early 1960s. This early exposition got the attention ...

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 ...

Using a few items from around the house you can create a simple circuit that will teach the entire family about electricity. STEP 2: Use the wire cutters to remove the plastic from the ends of the ...

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular Microchip ...

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA. To view the ...

As STEM learning becomes more mainstream from elementary to high school, more products that are STEM-specific are hitting the market. One such product started off on Kickstarter, and after being ...

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 ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...

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