I'm building a Babylonian/Hebrew hours (relative hours) analog wall clock that will show planetary hours
I had been searching the longest time for a way to somehow build a relative hours (solar daylight hours) analog clock such as the Orloj in Prague, orbat St Paul's Cathedral in Munster. But I also wanted to keep track of planetary hours according to Babylonian/Hebrew relative hours.

With Arduino controllers and DCF77, I've finally found the way I'm going to do the trick. I'll do some mods to the clock face to show Babylonian/Hebrew morning/evening hours and I'll add a planetary hours face in a planetary heptagram (for the 7 classical stars of the 7 days of the week) form that I will set the stepmotor to rotate in increments of 51.43 degrees per hour, thus creating a perpetual planetary hours time keeper. I ordered an old clock just like this off eBay yesterday. Really excited about getting started. When I finish, I'll have the only known Hebrew hours and planetary hours electronic analog clock in the world. It'll be one of a kind, because what I was looking for doesn't exist. So I'm building it.


Take a look at this Instructable. This guy does amazing work.

The DCF77 atomic signal is kind of an amazing thing, actually.

You can now literally rebuild the Orloj in the form of a small wall clock on an electronic Arduino platform.

I mean, if you had a hundred grand to spend, you could build it mechanically, but now with a bit of code and an old train clock from the 1930s, you can build it in your room on a budget.

Check out his perpetual calendar and tide predictor. I bet with some from tweaking from the Hdate C library, I could turn that into a perpetual lunar calendar to show hebrew months, too (or a Mayan calendar).

That's all electronic Arduino controllers and stepmotors.

It's really amazing.

Oh, by the way, you could very easily add a canonical hours face to this.

When my old broken clock arrives from eBay, I'll refinish it and gut it. Then I'll start working on some designs.

My ultimate dream clock would show luni-solar calendar, planetary hours, Babylonian/Hebrew daylight/nighttime mean time, and canonical hours.

That's just amazing to be able to do in analog format with electronics and step motors alone.
