A nicer voltmeter clock

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

This is gorgeous. I really need to hunker down and learn 3d modeling. It unlocks so many options from cnc to 3d printing.

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.

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)

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

I expected seconds arrow to move much more smoothly than in the video is 10Hz control just too slow?

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

This is beautiful, and I like it a lot, but I was slightly disappointed to find that they do not function by increasing the voltage as the day goes on. But then I remembered that that's how pins work. It IS measuring voltage!

Very nice! I skimmed TFA, came back here to ask for the obligatory 11:59:59 rollover, but then went back and found it.

The build itself is absolutely wonderful! This part is totally my hangup, but a second hand that has to reset bugs me to no end. :/
