Software, experiments, and things I make.
I'm Earl Hayes, a software engineer who makes apps, browser games, open-source tools, websites, and 3D designs and prints.
Each card shows where a project stands and, if it's public, links straight to it.

Making the Huion Keydial Mini K20 work on Linux
The K20 had no Linux support, so I wrote a driver and a visual editor for it: all 18 keys and the dial, over Bluetooth or USB, with no root at runtime.
Now building: Doodle Bluff's free beta and Cache Pal's Wear OS and watchOS companions. About the maker
