I am designing a keyboard primarily based on Kinesis Advantage 2. I am going to be using flexible PCB like the actual
Advantage2 to get the bowl shape but might add in a few more keys like where the Ergodox places them.
I am considering re-designing the thumb clusters but want to know what would be the best alternative.
The two biggest alternatives i'm thinking of are:
- Thumb arcs like Keyboardio
- Clusters on a sloped opposable plane like the Manuform
Any other designs i should consider?
