This analog meter clock was built by [Len Bayles]. Its 3 meters are controlled by an AT89c2051. The circuit itself is very simple, and available on the site. The meters are powered from a DAC, with a quad amp in between to keep the meter from drawing too much current.

The op-amps are not for keeping the meter from drawing too much current. On the contrary, they are there to provide enough current to the meters :)
This is WAY better looking than the multi-multimeter clock
Those gauges remind me of the water/coolant level gauges in the control room of the reactor in The China Syndrome for some random reason. :-)
I think this guys site might be running on an Arduino…
I think it’s TIME for HAD to stop with the oh so pedestrian clock “hacks”.
They’re like a preschooler’s finger painting destined to hang on the family refrigerator.
I love clocks, and I like these processor-based timepieces with interesting display devices.
Keep it up.
Cool clock… but does it still qualify as an “analog” clock? :P
Where can one get some meters like this?
I quite like clocks too so I don’t mind these stories.
Let’s face it, HAD can’t come up with cool high level hacks every day. 30 seconds looking at stuff like this is fine IMHO.
clocks are far better than haters
Lol, there does seem to be an obsession with useless clocks on this site. I am OK with that.
I had this same idea over two years ago… Too bad I never got around to actually building it. My idea was to use an ATmega8, three 8-bit R2R DACs and three opamps. Just like this one.
Here is my concept drawing from two years ago:
