[time-nuts] Timing for Pendulum Astrolabe?

[Brooke Clarke]

Hi Dana:

I converted a stock 24 hour wall clock to sidereal time using a "Crazy Clocks" module:

http://prc68.com/I/QuartzClk.shtml#Sidereal
I gave it to the local latitude observatory
https://www.prc68.com/I/UkiahObs.shtml
and used the LMST app on my Android phone to set it.

Have Fun,

axioms:
1. The extent to which you can fix or improve something will be limited by how well you understand how it works.
2. Everybody, with no exceptions, holds false beliefs.
