Basically cut the heads off the keys and put them in line with a bike chain. Interesting idea.

One pipe clamp and a bit of metal and you have a belt clip. Pretty simple idea.
Too funny. And Ironically would be pretty sturdy of a build too.
The author built a simple robot that climbs up a rope, and then cuts the line.
Not so sure if I could make the metal bits/spacers (no lathe). But I like the build overall. This would be a nice add to a CNC. Only issue is torque…not so sure you can get enough from a vac for a CNC.
I have seen a few of these builds now. They look really nice but…is it worth it? I know you can get cheap BT speakers for $20. Nice ones are well over 100…
Hum…I wonder about doing this with a bucket based system too.
I like the build. Its pretty veritable but….wow allot of work. I would have made a few things a bit more simpler.
I seem to see alot of these being built these days with an arduino based controller.-
