4x4 Macro Pad with Rotary Encoder

thingiverse

Update 4: Removing the WIP mark, the prototype is working fairly well as far as it goes. I switched to a pro-micro from the teensy 2.0 due to its smaller size. To make it fit, you must snap off the back edge of the board holder and secure it with hot glue. Hand-wiring was a bit tricky since you have to mentally reverse some layout going by the PCB design so it works, which makes more sense as a guide for the matrix when imagined upside down. I recommend checking out this hand-wiring guide if you need help: https://deskthority.net/viewtopic.php?t=6050. I can try to lay out wiring on paper if someone gets stuck and has uploaded my firmware hex file, keymap.c, and keymap.json for the qmk if anyone wants it. My next version will be a remix of imchipwood's PCB from here: https://github.com/imchipwood/dumbpad. I made the second prototype with gateron mx style switches as they are needed for the pcb. The keycaps are SA Profile keys from elsewhere on the site, but I don't recommend them as they had to be trimmed and sanded to work with switch stems. Update 3: I redesigned both tops to reduce thickness in the key mounts and tweak the size of mounting holes (keys were very tight). I also moved the mounting hole for the rotary encoder to be more central on the right and added a knob from lukie80's design. For the bottom, I added some space for the teensy and tweaked the opening for the USB port since it's B Mini. I will have new switches, diodes, and encoders tomorrow and take picks of print #2 with Cherry MX / Gateron style switches. I will also manually wire it up and try flashing the firmware too. Update 2: I redesigned the tops to have Alps and cherry mounts separately, which makes it print better. This is a 4x4 key macro keypad with rotary encoder completely designed by plagiarizing more talented people's work :). I've been using the volume knob and case designed by lukie80 for several years now and the 5x5 Numpad designed by DeepfriedchriL possibly longer. I loved the aesthetic of the volume knob, and the size of the knob is just right - and the 5x5 numpad was my first ever hand-wired diode keypad.

My intention will be to hand-wire this prototype and modify the QMK firmware used for imchipwood's dumbpad (https://github.com/imchipwood/dumbpad). Later, I will most likely revise this case to utilize the pcb included in the dumbpad design with newer switches and keycaps, etc.
