You might wonder why [Kevin] wanted to build digital calipers when you can buy them ... waves with different phases into the assembly and measure the phase of the signal you receive.

But perhaps more importantly, this is also the cue for an examination of high precision dimensional measurement. So I’ve assembled a collection of micrometers and vernier calipers of varying ...

A hobbyist assessed CNC lead screw accuracy by building a setup using digital calipers interfaced with a Raspberry Pi. These calipers transmit data via a 76 kbps synchronous serial protocol, requiring ...
