Engineer Bo builds a wireless, high-resolution scroll knob from an encoder wheel and shows how smooth, fine-grained scrolling feels in use. It is a build log of a custom hardware input device.

HN people point to it as a rare example of fresh input-device work and pair it with other DIY encoder and haptic knob projects.

That's mostly copycats of Ben Heck approach from 2012 - some technical improvements, but like without understanding, further thinking about function - or imagination why someone needed it first, then what would be next. So all seems stuck for me, and not much than a bit a closer since then to what (and how) I want, starting from smoothly increasing the repeat rate with pressure for cursor keys or scrolling (but not to have few levels only to macro-simulate that, then OS's are used to not get such things right - High Resolution Scrolling ▶ this video 2024).
