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

Touch-free user interfaces are the new trend for automotive design engineers. There are multiple ways to implement this feature, and one of them is through proximity sensing. Proximity sensing is a ...

A second automaker has realized that going all-out on capacitive touch buttons is the wrong move. First, Honda backtracked, giving the 10th-generation Civic a physical volume knob to replace the touch ...

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 ...

Rotary encoders provide critical information about a motor shaft’s position, rotational direction, velocity (rpm), and acceleration. They are vital components in motion-control feedback loops used in ...

It can sometimes feel like the arc of progress only moves in one direction and that it’s always making our lives worse. As car makers get turned on to technology—pushed by customers begging to see ...

Electric guitars are great, but they’re just so 20th century. You’d think decades of musicians riffing on the instrument would mean there are no hacks left in the humble axe. You’d think so, but you’d ...
