Just finished a Harbor Freight $10 caliper DRO using an Arduino Nano for the computer horsepower. It mounts on the cross slide of my Grizzly G4000 lathe. This version has a feature that measures the Diameter of the workpiece in addition to the ordinary X-position. No more stopping to make...
I'm not sure how many (if any) are interested but I had some spare time tonight and photographed some of the items I have found at car boot sales over the past few months. Wanted to list them out anyway for my own reference so thought I could share.
Will add a bit more to the descriptions etc...
