This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as any other servo tester, the difference is that it can be programmed to do ...

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that ...

Inspired by the creative genius of Martin Molin of Wintergatan fame, [iSax] set out to create a robotic MIDI-controlled trombone. It takes years for humans to develop the control and technique ...

As wonderful as mechanical keyboards are, most of the pre-fab and group buy models out there have zero media controls. If you want rotary encoders and OLED screens to show what function layer you’re ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

I've completely swapped my home over to LED lights, and for the most part, I love it. The energy savings are real, and I'm a sucker for all the smart color changing tes. But my biggest grievance is ...

More than one-fifth of US electricity is used to power artificial lighting. Light-emitting diodes based on group III/nitride semiconductors are bringing about a revolution in energy-efficient lighting ...
