In the application you describe I would rather expect the USB to act as a battery replacement. Though USB is 5V and the reader heads use a 1.5V battery, so this might be a dangerous assumption.
<finds caliper with missing battery cover> The scales can be powered through the data cable. This would be useful in many fixed installations. However, they do not like 5V. I experimented and things went wrong (no smoke, but all LCD elements turned on) at 2.1V. So, don't plug the USB into a USB socket without doing some careful tests with a current-limited variable power supply first. This probably isn't relevant to this query, but there are 3D-printable connector designs: https://www.thingiverse.com/thing:2477494 as an example. In a bit of a coincidence, CTC just spammed me with an email informing me that they have 50% off digital scales, code DS2022 https://www.ctctools.biz/digital-scales-dro/ -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
