I'm the guy who supplies Woz with his Nixie tube watches. I've had to repair a few of them after too many Segway polo matches. They get just as crusty as anyone else's watch.

I briefly thought about selling the broken parts on eBay, but it seemed a bit too squicky. Although you know the auction would end up on Reddit.

You will wait quite a while to get a charge that way. The devices negotiate the charging current over the data lines. The default is either zero or 100 mA. Best to buy a purpose-made USB data isolator that negotiates a good rate with a built-in microcontroller, but doesn't connect the phone to the charger data lines.

You can build one using a few resistors. See Adafruit's MintyBoost.

I work in a lab where we make radio receivers that work at frequencies around 460 GHz. As it is, we have to use a mixer diode to convert to a lower frequency (10 GHz) before amplifying the signal. This technology would be well suited to this application, provided that the noise is low enough. We already cool the mixer to 4K in a vacuum chamber.

Underwater robotics is all about advancing the state of the art. A machine that lived six years was reaching obsolescence. I'm sure that the boys in the back room will have fun building its successor. (I have helped to build a few underwater robots for competitions, and it's always a joy to start work on the next one.)

I seem to recall from my BIOS writing days with CP/M, that the 8" drives had twice the data rate of the 5" drives. They also spun faster, 360 RPM vs 300 RPM. The 8" IBM format was soft sectored 26 sectors of 128 bytes, and the 5" used 16 sectors of 128 bytes or something like that. too many numbers to remember.

At any rate, the four 8" floppies that I still have in my meager collection are all different, for different CPUs, OSes, languages, different sector formats, etc. The closest I came to inter-system compatibility was to write a CP/M floppy reading program for the PDP-11.

Many useful items that one could build require some metal bits in addition to 3D printed parts. I've recently encountered this situation when trying to make a little gizmo with motor drive. Small gears, shafts and so forth are very hard to come by. Have you considered starting an ancillary industry that provides the sorts of things that the company Small Parts used to offer, before Amazon killed them?

Them as has, gets.
