TheUltiPad - a 23 Key Number Pad/Macropad with Rotary Encoder

thingiverse

I really loved the dumbpad designs I made earlier when using my full 104 key keyboard, but recently switched to a Drop CTRL tenkeyless as my daily driver....and I found that I missed numberpad functionality for specific daily tasks. So I designed a numberpad with all the features of the macropad app launcher - with rotary encoder.....Therefore---TheUltiPad was born! Shown next to the CTRL for size comparison, its a little taller than I wanted, but had to add some height to account for the pro-micro along with hand-wired switches, rotary encoder and LEDs. I will be uploading raw QMK firmware folder and hex shortly, not yet in position to fork and commit files, but it forks well and derived from dumbpad firmware. The LEDs display Num-Lock at top of three, and Layer indicators above each layer switch - they are setup as TT() keys so they are both momentary and toggling. Parts List: 1. 23x Cherry MX switches of your choice (I use some Cherry blacks that I had) 2. If you choose Costar or Cherry MX Stabilizers (I removed Alps Stabs topas the bar collided with switches, and I am using it fine without stabilizers) 3. Really nice mxuteuk 35mm machined aluminum knob from Amazon 4. 3x 5mm LEDs (and appropriate resistors) I used these from Radio Shack 5. Diodes: In4148 - You can get a cheap 100 pack from Amazon 6. EC11 Rotary Encoder: Here is a 10 pack of EC11's from Amazon 7. Pro Micro: 3-pack from Amazon 8. Any USB Type B Micro cable for the Pro Micro 9. 4x M4x12mm socket head machine screws 10. Various wire, soldier, etc. Firmware notes: 1. UltiPad.hex (precompiled firmware) 2. UltiPad.zip (firmware folder for QMK build env.) If you want to use compiled hex: 1. The Keypad is the numpad as labeled 2. The 4 top keys as PREV, PLAY, NEXT, STOP. 3. The rotary encoder is Volume Up and Down, with button as MUTE. 4. The two bottom keys are setup as TT(1) and TT(2) (both a momentary and toggle with double tap) Unzip the UltiPad.zip into your QMK folder in your build env, and modify/compile your own keymap. Let me know how you make out! Edit, added a slightly shortened bottom half (by 3mm), its the bare minimum to fit my internal parts.
