I am a long-time user of a DataHand keyboard. With the scarcity and rising cost of second hand DataHands these days, I wanted to ensure that I always had access to a DataHand-like keyboard. And so this project was born.
The overall functionality of the lalboard is obviously heavily based on the DataHand, but I designed all of the specific key mechanisms, etc. from scratch, to be printable on a normal hobby-level FDM printer.
