open hardware Digital readout panel

Post by KW1252 »

For anyone who has a mill and/or a lathe and absolutely hate figuring out the hand crank scales, here's a bit of help, a digital readout panel :)

I know the scales for these are cap sensors, on a PCB, I've always wanted to make my own PCB and do it with out the china connection. Anyone know of a project that might be a good start for that PCB layout?

Some more about the caps in digitial calipers, see the section where it notes "Digital calipers contain a linear encoder"
