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.
