alt Hacker NewsAuthor here! :) This article is me sharing something that made me really happy, wanting to show others how they can do the same.
I see some comments pointing out that the clock wouldn't need to run in the browser. I picked this option to make it simple for folks around me to quickly prototype their own clock faces. This isn't supposed to be the cheapest or most efficient implementation, either; feel free to build your own LCD clock and then blog about how you did it!

Can it display the time on a set of scrollbars? :)
Its a genuinely nice idea, I do love the second clock face you've done, the sort of "fuel gauge" one. I think a great next step would be some sort of gallery of clock faces that people can use and contribute to, based on whatever code you've used to create them
Really nice visuals!
Could you give a little more information about the 'stack' you're using to display the clock?
From this:
> This minicomputer will power the clock. The Pi 3B+ seems just enough to render some simple animations.
> I also tried with a Raspberry Pi Zero 2, but 512 MB of RAM were too little to run a modern browser, sadly. I think a Pi 4 might be a good sweet spot between processing power and price, currently.
...are you essentially displaying a full-screen browser window in the default Raspbian window manager and then running local Javascript for the clock itself?
Next project: Dali circular clock (flexible OLED)
Impressive cable lacing. Nobody talked about that yet.
Indeed. Don't be dissuaded by Hacker News commenters. All the naysayers here doesn't seem to have published their own blog posts about how they built circular LCD clocks with Arduino ESP32 and low level programming or whatever they fancy as "good enough".
Browser based rendering that allows people to easily make new watch faces with JS and SVG is a perfectly reasonable platform for a nifty project like this. I think your watch faces look neat.
