From Ken Olsen of The Maker’s Box:
You never know what people will do with your ideas, and it is always fun to see someone do something I would have never thought off with them. I got a video from someone who built my Programmable Fidget Spinner, and used a leaf blower to see how fast they could get it to go. Fortunately, they were wearing safety glasses, and no, it didn’t come flying apart. It did, however, start displaying erratically at about 3600 RPM (the fastest I can get it by hand is just under 2000 RPM).
So, what is going on? TLDR: I figured it out and fixed it, and here is proof.
