This design shows how a piezoelectric transducer's acoustic output can be increased while minimizing the parts count and cost.
Using only generic components, this Design Idea implements an optically-isolated current sense topology compatible with DC sources of either polarity,...
This mini-series of articles describes how to build a computer’s CPU (central processing unit) out of relays.
This idea is a simple, modern take on a very old and very slick idea: balanced ring modulation.
An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity sensor.
Most amateurs and hobbyists use a twist-and-fold technique, but the Western Union Splice is mechanically stronger and results in a lower profile.
An electronic switch designed for battery-powered equipment is driven by a momentary push button that turns the power alternately on and off.
Production testing a video interface's complete path from the analog or digital front-end to the digital video input of a processing unit can be chall...
In addition to being the epitome of everything that flashing LEDs have to offer, this design is of an aesthetic style that would work well in most set...
This modern incarnation of a vintage display technology is making its mark in myriad locations, including retro art installations.
