Analog clock using amp meters. I had the idea for it about 15 years ago, but I didn't have the tools to build it. Once i got an arduino, it was easy to make it a reality.

Enjoy this project?

Lovelly piece! I'm into woodworking, I'm thinking of doing something of the like and doing a rustic little case. Does it work (ofc it must, but can you put some pic / video of it)?

  Are you sure? yes | no

It works quite well. There is a bit of drift because the crystal is not quite perfect. I have thought of reading the noise in the input power with the analog input to get the 60hz ripple from the AC. And then use that to keep time.
