I've played with simple electronics on the arduino and raspberry pi platforms but this is a whole new level. Anyone gone down this path? Something you would recommend?

And then yeah he's playing a Touhou rearrangement in the project intro video. "Original: ZUN".

I wholeheartedly support weebs who create useful open-source electronics and share them with the world.

Users find it hard to use documentation just as they find it hard to use a product with a bad interface.

It changed the way I write, for example: Headings are like boundaries to an API. I prioritize example before explanation. If it lowers cognitive load, repetition is warranted. I made the following changes: Even if it may feel like it has been too short, I hope you will not mind the sections. Even better, try to remove everything except for one idea per page.

Try not to write for the expert, write for the most confused reader. I’ll ask you the following: Do you see docs as some sort of ux too? How do you test docs, without watching someone live?

Anyway I'd be interested in the implementation of a 3D mouse also.

Anyone have any idea whether the touchpad part could be made open-source? Or even some closed sourced off-the-shelf solution that could be integrated with the above?

EDIT: There is a Canadian company that has recently released an open source trackpad called the Ploopy Trackpad [1].

The creator of it has showcased the prototype at an osu!* streamer's channel (since low-latency absolute positioning devices are highly desired for playing osu!): https://www.youtube.com/watch?v=v1afJ7OpacU

* that is osu! (sic) rhythm game, not to be confused with OSU universities
