    How to build a circular LCD clock, step 1: buy a circular LCD that looks like a clock.

    I'm not kidding, that's the extent of the build. They simply connect that display to a computer over HDMI. The only hacking here is browser-based JS for clock animations.

    Beat project, but

    You don't need a browser to display graphics. And you don't need to be a programming whiz either. I'm sure Claude could write some python to render these clock faces.

    Maybe you'll love my minimalist clock design https://euclid.tulv.in/

    you can also do this with an esp32 as long as you don't insist using a browser to draw a clock

      That's what i wanted to say also. The raspberry is a total overkill here.

      Nice implementation though!

      Yeah, LVGL is probably what you'd want in that environment.

    I found that the surf browser was efficient enough to run fine on my Raspberry Pi Zero W. YMMV with animations and such, but it's much better than any chromium alternative in my experience.

    Why do they need to be ...white :)

    Oh i see the cables now and cant unsee them.

    I guess next step is to 3D print a back case mount that encloses the RPi and plugs into a wall socket for power.

    That modak font looks similar to one in Pixel phones clock. But Nice thing you made there :)

    $159 quite expensive for the LCD

      It's an unconventional shape, and not subsidised by ads, etc..

      There's a multitouch function

    The cartoony clock looks a bit weird in terms of typography when the time is 10:29, the font kind of squeezes and becomes hard to read
