Eternal Keypad is an open-source input device for gaming that can be assembled for both right and left hand mouse users.
Historically there has been a scarcity of input devices for people that use their keyboard with their right hand and the mouse with the left, forcing some people to place their right hand in uncomfortable positions and/or requiring heavy remapping of in-game controls.
This device aims to fill this gap in the market that companies don't care about because the target is too small to turn a profit.
The device is Pro-micro compatible, so it's easier to build and source components.
- ETERNAL Keypad PCB
- x36 through-hole diodes. (I use "1N4148 CDIL" from tme.eu)
- x36 MX style switches
- x36 Kailh Hotswap Sockets
- x1 2u stabilizer
- Keycaps (The set pictured above is "Honey & Milk XDA")
- x1 Micro controller (Pro-micro or equivalent)
Optionals:
- x8 WS2812B RGB LEDs
- ETERNAL Keypad switch plate & bottom plate
- If you want to have underglow RGB you should order a laser cut bottom plate from acrylic, using the included
.dxffile. If you don't care about underglow you can get an FR4 bottom plate PCB using the gerber file.
- If you want to have underglow RGB you should order a laser cut bottom plate from acrylic, using the included
- x8 M2 Screws (I use "1154095 BOSSARD" from tme.eu)
- x4 M2 standoffs (diameter: 3mm, length: 8mm)
- 4x Rubber bump-on feet

Note:
- The "A" and "D" keys are not mirrored to avoid inverting movement controls with default key-bindings.
- The "FN" key is used to access the missing half of the keyboard
- Holding the 0 key turns WASD into arrow keys
