A load cell is a sensor designed to measure the weight of an object. Essentially, it is an aluminum bar containing 4 resistive strain gauges that are measured through a Wheatstone bridge to detect the weight of the object. In this project, using a small Microchip ATtiny1614 and a 5kg load cell, a 3D-printed scale…
Researchers Alec Peery and Dušan Sorma at Ohio University have been exploring a mechanical keyboard concept with a 3D-printed dampener built in, to avoid typing injuries. In fact the average computer user applies two to seven times the necessary force needed to activate a keyboard’s keys, slamming them down, then experiencing a sudden stop. So…
