From the project

A 36 key gaming keypad, for both right and left handed mouse users.

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.
