  I’m surprised that they chose to add a bunch of components to feed the AC line frequency to the microcontroller instead of just using a 32.768 kHz crystal. A single crystal oscillator seems like both the cheaper and more accurate option

The power line frequency is carefully monitored and adjusted to ensure that deviations from the ideal (60 Hz in OP's case) are smoothed out [0]. Even a single ppm deviation equates to 2.6 seconds per month, and your cheap 32.768 kHz crystal is going to be orders of magnitude worse than that.

I think this package does exactly what you need: https://pkg.go.dev/github.com/google/gopacket/routing. Works on my machine (error handling left to the reader)

    router, _ := routing.New()
    iface, _, _, _ := router.Route(net.ParseIP("8.8.8.8"))
    fmt.Println(iface.Name)

this prints my Ethernet interface as expected. It doesn't make any requests, it just figures out where to route a packet. I guess it interfaces with the OS routing table.

That has nothing to do with the UI framework. The X11 dependency comes as part of the clipboard integration (which I'd argue should be optional or even removed). Still, I wouldn't call it modern if Wayland is outright not supported.

Cool project. Tip: acetone will readily dissolve the plastic parts of the card leaving the antenna(s) and chip intact. I believe a few other people have made drop-in PCBs with NFC antennas. Here’s one: https://n-o-d-e.net/datarunner.html

Also, no F-91W thread would be complete without a mention of the sensorwatch project: https://www.sensorwatch.net/

The peak is a handful of requests per second. If you have a static site, the cheapest Hetzner tier handles it just fine.

Most services just include cleaning and relubrication. Parts don’t wear out that quickly.

Most watches from before the quartz crisis (pre ‘70s) used standard off-the-shelf Swiss movements for which spare parts are still readily available. It can get tricky with expensive or rare in-house stuff like Omega and Rolex though.

My drawer is already full of radium dials. I'm not sure adding nanoparticles to the mix is a very good idea.

I've never heard of index matching fluids! Will have to read up on this.

I tried, but they're very difficult to cast. Epoxy resin is also very brittle and difficult to cut neat and square. A jagged edge does not bond very well to a smooth surface.

The minute hand is set to 43-ish minutes past the hour while the hour hand is showing 15-ish minutes past noon/midnight. If you’re used to reading analog watches it’s jarring.
