on the chamfer/bevel; looking forward to seeing updated pics!
More ideas on OLED (just more detailed of what I was mentioning above, understood brightness/contrast is likely a no-go):
Auto-off function after set time of no rotary-encoder input detected (has a real-time clock after all :-). Auto-on when rotary-encoder input detected resetting auto-off function timer whenever rotary input is detected.
Default to just showing clock on entire OLED screen (nothing else) when no rotary input detected for set amount of time. When rotary input is detected, show pertinent info for current function.
Ability to turn off OLED when unwanted/unneeded via the rotary-encoder menu system. When OLED is off, just push rotary button to turn it back on and goes into whatever function was set to defualt.
Also ability to enable/disable above auto functions.
Considering Knob and case. I didn't find a mention... Will the case be shaped around the contour of a round knob for the hole? Or will it remain a square, well rectangle for entire vertical column? It would look much more polished, and I'd be willing to pay a little more, if it's a little more, to have it looking like it belongs there instead of a round peg into a square hole
