Lowly priced digital calipers have been available on the market for some years. Most of them are produced in China or the Far East and possess a serial interface, over which measuring data can be transferred to other devices. Despite their price ($10 - $20) these calipers are very reliable and precise. Apart from the original use as calipers, they can be used as position display or Digital Readout DRO for linear axles of small machine tools in the same way as linear glass scales. For this purpose digital scale readouts with mounting brackets are available in different lengths. In small CNC machines these scales can serve as reference givers and tool length givers. Even a 3D Digitizer / 3D Scanner for 3D measurements can be easily implemented. A complete hobby workshop can be digitized for little money.
