Made small but pretty practical and important addition for my another bigger-grade PSU. I wrote earlier about this PSU in my blog, check that out for background info.
This addition consists of ammeter, switch, low-voltage side fuse, couple banana posts (gnd, +/-). Spacing between +/- is 2.75'' or whatever is used at those normal wall plug/scope adapters, just for practical reasons. This psu is floating so i installed both hard-earth and negative posts.
Case itself for these stuff are pretty much hand made from 1mm thick steel (shown in photo, was originally without paint, now with spray-paint.
Other case parts are made of holed steel plates i had salvaged from other place.
Panel case is installed at PSU case by screws, so it's possible to take it off, if needed.
Wiring i put inside PSU, with heat-resistant cable to back-panel, where output would normally be.
