Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

They're reference designs for a reason.

Arduino is a microcontroller designed for real-time hardware control with very low power use. Raspberry Pi is a full computer that runs operating systems and handles complex tasks. Arduino excels at ...

Discover the surprising way a magnet and coil can power an LED! In this video, we explore the fascinating physics of electromagnetic induction, showing how moving a magnet through a coil of wire can ...

ViBRANT, a surrogate nuclear reactor, simulates neutron behavior with light to support safe development of advanced ...

If your car came from the factory with halogen or HID bulbs, you’re going to need to replace them or upgrade them down the line. Both of these bulb types lose light output over time; thus, even if ...

A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of ...

Tyler has worked on, lived with and tested all types of smart home and security technology for over a dozen years, explaining the latest features, privacy tricks, and top recommendations. With degrees ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

We’ve always been interested in fluidic logic and, based on [soiboi’s] videos, he is too. His latest shows how to use silicone and a vacuum to build a multiplexed dot matrix display.

Sometimes you’re looking for a component for a project that you know should exist, but you just cannot find it. Something like a 14-segment LED display, but not just one with a fixed color, ...

Our museums, education, and research centers work at intersections that spark imagination and encourage discovery—between art and the environment, space exploration and women’s history, cultural ...
