Automated winding machine features a self-reversing screw
The world of mechanical engineering is full of interesting and ingenious mechanisms. The Geneva drive, for example, translates rotary motion into intermittent ticking — perfect for a wristwatch or clock. With a clever mechanism, one can reduce the need for complicated control electronics.

Pondering some fundamentals
Firstly, about USB "gen1" and "gen2"...
USB gen1 versus gen2
I posted about buying a 4TB SSD and putting it into a USB gen1 caddy, then doing a complete OpenEmbedded compile:
https://bkhome.org/news/202303/oe-compile-1662-packages-in-1-day-16-hours-and-15-minutes.html
...very surprised with how fast it was, but noted that a gen2 caddy will probably be even faster.
The terms "usb3.0", "usb3.1" and "usb3.2" just muddy the waters. All that we need to know, is the USB interface "gen1", "gen2" or "gen2x2", as these latter specify the speed; 500MB/sec, 1,000MB/sec or 2,000MB/sec.
Although gen1 seems an ok match for the SATA SSD, I thought that throughput might be improved with a gen2 caddy, so bought one of these, Simplecom SE229: [...]
