  • Cool! I was at least hoping for an op amp or two for the circuit however ;)

  • Nice! Needs just a tweak to prevent the overshoot and bounce when going from high to low.

  • I love using analog meters in digital projects. Here's a few different places I've used them.

    Minecraft Server Meter:

  • I built one of these recent after Princess Auto had an amazing deal on surplus meters like these. They were under just over 1$ each and I bought a lot of them.

    The one I built isn't as nice, but it's a really nice way to display the time and people are mildly fascinated by it when they see it.

  • So sexy! I could probably build the electronics easily enough, but such projects need workworking tools I just don't have room for in my tiny flat.

    (nor would the missus be pleased for me to buy them - but that's another matter)

  • I saw somebody's arduino based voltmeter clock way back around 2014, I think here: https://maniacallabs.com/2014/07/08/meter-clock-pt1/

    I thought it was pretty cool, but a bit expensive for what it was.

    So I made my own with a PIC chip: https://www.n1kdo.com/meter-clock/index.html

    Mine is more of a novelty than a accurate clock. It is a interesting desktop geegaw to invite discussion.

  • I always enjoy projects like this. Both because the are artistically neat and because the give me all sorts of ideas.

  • Funny, I've been playing with panel-meters as well…

    I have an analog computer I'm finishing up. I have ADC's to convert the analog to digital to display the values on an LCD (with an ESP32 dev board—it was more flexible than panel meters, cheaper than an oscilloscope).

    But because looking at "simulated" panel-meters seemed to kind of undercut the point of the analog computer, I went ahead and created a small PCB to go from my analog computer to a panel meter like the one in the clock.

    Running a "Spring + Mass" simulation on the analog computer and seeing both the LCD/ESP32 representation of a panel meter and an actual panel meter move in sync brought it all home.
