Riva,
I'd planned to implement the prompt strings in PROGMEM up the top, but late last night found it easier to just implement a character at a time at that point in code. I've now done so (was easier than I thought, but hey - you don't have to understand code to copy it and fiddle it in to working!)
I plan to have my buttons recessed into the side. I've built up a few toys (CNC router, laser) that I'll be using in the build. I plan to make the clock body with light baffles etc all from one piece of wood, with an acrylic (perspex) from and back cover.
Attached is new revision which uses messages defined up top of program (easy to change) for the prompts in time setup.
I should note I haven't actually changed the daylight saving stuff (dates etc) just changed the naming to DST (terminology with use in Australia)
