[Bertho]’s submission for the 74xx logic contest is really impressive. He designed a capacitive sensing touchpad using only 74xx and 40xx logic chips. We’re impressed with the build and his writeup is ...

Capacitive sensing as a user input medium is no longer a fringe technology relegated to select products. It is now a mature technology employed in thousands of products and millions of units.

Capacitive displacement sensor’s touch-free nature makes it ideal for fragile surfaces and high-speed machinery.

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...
