I've wondered how the digital calipers work, mainly to try to figure out if it would be possible to modify the cheap $10 HF calipers on a planer or router lift rather than by the expensive versions that are made for those purposes. Sparkfun disassembled a set in one of their recent new product videos. If you're curious, you can catch it here, starting at 3:10.

It looks like there is a lot of potential for new uses.
