Probably 3D printing and some light sanding/painting.
no LED planned. What is rotary? Not much extra planned. Would be nice with a windows disable button tho. Chances planned is num pad button moved up.
well that makes it easier.
rotary.... rotary encoder, been popular on some recent group buys (example: Satisfaction 75 & many others)
windows disable... can be done in the firmware, just switch to another keymap that doesn't have that key in the keymap.
if it's your 1st handwire, i'd suggest keeping the wiring matrix simple and going with a larger controller like the
teensy ++2.0.
if you want to use a promicro or
postage board you'd have to do a more complicated matrix wiring. one method is the
crushed paper matrix (as mentioned earlier in the thread)

- cannibalized network cable (cat5 or cat6) is pretty common and easy to work with (24gauge solid core)
- magnet wire can be a pain (the enamel is harder to strip than you think)
- some use old ATA ribbon cables for tying the matrix to the controller (to keep it tidy)
- small gauge stranded is fine too
- really anything will work, either what you have on hand or want to pickup
depending on where you want to locate the controller
- either at the edge, using the controller's usb port as where you plug in your keyboard
- add a usb breakout board, locate the controller wherever you like, usb breakout will be easier to mount in your 3d printed shell
i can trow together a diagram and help you with firmware when you get to that point. it's usually the most daunting part of anyone's 1st scratch build.
can you post a link to your KLE (keyboard layout editor)?
