Just a general query: I am trying to find anyone who has used/purchased a fully “OLED” keyboard. Best example I know of is artlebdev’s Opitmus Maximus from 10 plus years ago. While I search for the technology and techniques to make and program my own, I would like feedback from users of any types of programmables. Help me avoid the low hanging fruit of initial pitfalls.
BTW: What is hhkb? and what does it represent in real world practice?
