A Nicer Voltmeter Clock
Key takeaways
- I didn’t come up with the idea, so I never really blogged about the design; I just built one and kept it on my office desk.
- The idea endures, but most of the designs I see on the internet are needlessly complicated and not all that pretty, so when I decided to build a revised design, I figured it might be good to document it better.
- Customizing 5 V panel meters.Note that the new hour gauge has 13 divisions, from 0 to 12, while the minute and second templates have 61 divisions, from 00 to 60.

The idea endures, but most of the designs I see on the internet are needlessly complicated and not all that pretty, so when I decided to build a revised design, I figured it might be good to document it better. The process started with a rough mockup in a 3D design program:
A mockup of the new design in Rhino3D.For this version of the meter clock, I opted to use three generic, 90° panel voltmeters from Amazon (link, about $9). I disassembled them, took careful measurements of the faces, and then printed replacement decals on adhesive paper. Printable PDF templates can be found here.
