Chording keyboards can be difficult to learn, and they're not as common as standard keyboards. I tried to learn chorded typing but failed, so I came up with the idea of a full-size QWERTY keyboard I could wear. I used guitar buttons to attach the keyboard to a strap, so I can position it anywhere. It's comfortable and lets me type with my arms relaxed. I want to design a keyboard specifically made for wearing.
Techno fanny pack
I came up with an idea for a wearable QWERTY keyboard that looks like a mini keytar. It will have pushbuttons to switch typing layers and trigger macros. The keyboard will position the keys in a line. I plan to use 2020 extruded aluminum and laser-cut plywood for the first version.
Phone notes
I revised my ideas for a wearable QWERTY keyboard. I thought about using ModuKey hardware, but it's not feasible. Instead, I want to learn the diode-matrix method used by many keyboard builders. Also, I want to add a MIDI synthesizer and music-playing functions for impromptu jam sessions.
KeyBoardolier mind map
I looked up the Cherry MX keyswitch mounting dimensions to refresh my memory, drafted a 75-key layout with a gap between the hands, and added a reinforcing piece of aluminum in the channel. I placed holes along the edges to add standoffs for support.
CAD keyswitch layout
I experimented with different keyswitch hole designs by making a plate with three styles to fit in a tin. One had plain squares, the other two had cut lobes and rounded corners. I painted the wood after testing the fit.
Care Bear Keyboard
I used Cherry keyswitches, copper wire, and rectifier diodes to build the Care Bear keyboard. I soldered the wire to each keyswitch and added diodes to bridge the columns. I messed up the diodes, so I will see how that works when I program it.
