I think right around the time when I watched his video, I got my risc-v CPU inside an FPGA working, including interrupts. I was very hyped about building such a mouse with it, just to prove to myself that my CPU can actually do something "real". It don't need to be the fastest, lightest, smallest, but a small robot that can solve a maze would be cool.
Then I tried to lay things out and realized how much more work that'd be, so I dropped the project (for now).
One day I'll build one though! It's only a matter of years, I think.
Wow, these mice were a lot faster than I expected. In the last part of the video, they talk about fans in the mouse that suck the mouse to the ground to prevent slipping.
The first time the video shows a mouse, I was annoyed by them showing a very clearly sped up recording, which made it difficult to follow. Only later it dawned on me that it's real time, not sped up.
