Can any of you electronic wizards write up some instructions so I can install a pot on the front of the display to adjust the night (lights-on mode) RPD brightness? I guess I could cut a slot for a thumbwheel pot on the top of the unit if the dimensions inside the case are too tight for a knob pot on the front. The main thing is knowing where to solder my wires (if such a thing can be done). Or better yet, for night mode only, maybe I could have a pair of trim pots and a pushbutton switch to go between the two. That might be more durable, considering I'd be using it a lot. Thanks in advance!
