Conversion of the analogue panel meters on my Maas SPS-50II Power Supply to a couple of 3-digit LED meters.

With the rest of my gear having digital displays I decided the Maas Power Supply could do with the same, courtesy of a couple of cheap 3-digit LED digital voltmeters from Ebay.

Update post blog:
The cheap LED DVM's I used did have one problem, they are very unstable in regards to temperature/humidity changes in the workshop. However, 2 or 3 good layers of conformal coating has fixed that and now I'm seeing only 0.1 digit changes instead of 1.0.
