Your Keyboard Sucks and I Can Prove It. - Labs Keyboard Testing

The video from Linus Tech Tips Labs presents an in-depth look at their keyboard testing apparatus and methodology, centered on proving or disproving claims about keyboard performance. It introduces a dedicated robot named KAVE that is programmed to apply precise forces to keyboard keys, capture data, and help determine actuation force, travel distance, and timing with high repeatability. The host explains the limitations of traditional quality control in keyboards, arguing that a product can pass manufacturer tolerances yet still fail in real-world use due to subtle variances in feel and reliability. They describe the testing workflow, including how frames are captured, edge detection is applied, and how the robot aligns with the keys to obtain accurate measurements. The discussion highlights plans to expand the setup to test more keyboards, improve data collection speed, and eventually publish a public information repository with standardized test results and tear-down images. The video also covers future directions such as upgrading to a 3D laser profiler, evaluating latency end-to-end, and separating keyboard data from display latency for clearer comparisons. Finally, the hosts tease broader ambitions like a sound library and an accessible rubric for evaluating different keyboard attributes beyond just switches and latency, aiming to empower consumers with concrete, comparable data.
