Using a Laser Cutter to Replicate an Optical Comparator Screen

A frosted glass disk with geometrical markers

Precision instruments often contain specialized components that are essential to their function, but nearly impossible to replace if they fail. [Andre] had just such a problem with an optical comparator, …read more Continue reading Using a Laser Cutter to Replicate an Optical Comparator Screen

Budget-Friendly Bend Sensor Deforms with Precision

We’re pretty familiar with budget resistor-based bend sensors at this point, but this sensor is in a totally different class. Instead of relying on resistive elements, [Useok Jeong] and [Kyu-Jin Cho] devised a bend sensor that relies on geometric properties of the sensor itself. The result is a higher-fidelity measuring …read more
