You need to buy the board that works with your scales

You can use an Arduino which is much cheaper.? The code is available here ...??? ? a continuation of Yuriy's original code.
But I believe it only works with iGaging scales.

It's not a new idea, but Mark and I are working on using a rotary encoder to replace the magnetic scales which would be cheaper (encod ers can be had for less than 20.00 GBP these days), but the major advantage is doing away with a bulky scale parallel to the cross slide, usually a big problem on small lathes. The scale will be replaced by a 0.3mm dia steel cable housed in a little duct or tube.

It's early days, but we think it should be viable.? Mark has already modified an Arduino MKR board to run Blue Tooth instead of Blue Tooth LE and written the sketch.? I'm trying to catch up with testing and the mechanical side of things!? The plan is to run the Arduino serving both axis, off rechargeable lithium batteries.? This arrangement would mean an enclosure at the back of the cross slide could transmit direct to touch DRO on a tablet with no wires dragging in the chip tray.
