Had a long conversation with Troy about the hinge keyboard design today. Having used the Katana for a while now, I've been thinking of more ways to improve the design.
We're still doing some research in the run up to an interest check/group buy. The most important developments are related to a PCB design. Having a PCB for the board will allow a much thinner build, something which will appeal to all potential buyers of the board - myself included.
The size of the board is important too. There are two priorities we're considering: portability and desktop use (stationary). For a portable board we're going for 4 rows of 7 single keys (4u x 7u) in an ortholinear grid. That's an extra column of keys per side.
For the larger board, we're thinking of 5u x 7u. That's one less row than the last prototype, pictured.
We originally thought we could get a group buy going in the summer, it's still possible, but it will certainly be tight.
Watch this space.
