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.

I recall seeing an Android app several years ago which could at least
display LMST, but I could never use it. It would only accept position via
the built-in GPS, not by manual entry as an alternative. My cheap
mini-tablet's GPS receiver was so insensitive that it was virtually
unusable. Curiously, last summer it came to life and worked well
for about half an hour, then quit again. Go figure...

Is David White still in business?
YES. David White’s SitePro is now based in Lafayette, IN (near Purdue
University).
http://www.dwsitepro.com/
The David White name is known for high-quality surveying equipment and
optical instruments. The David White Company was founded in Milwaukee,
Wisconsin, in the year 1895 by Mr. David White. The founder was born in
Hungary and his occupation was that of an instrument maker. After
immigrating to the United States he started the company with the help of
established relatives in the Milwaukee area.
In 1900, he organized a partnership with Charles Klaweither, as they were
both involved with manufacturing drawing and surveying instruments. The
company was incorporated on June 22, 1912 and it's products became widely
recognized for craftsmanship in specialized optics along with the name for
high quality.
How old is this David Clarke Astrolabe?
Most likely the last number (on mfg. plate) is the internal mfg. serial
number,
which would suggest a 1945 manufacturing date.

Subject: [time-nuts] Timing for Pendulum Astrolabe?
Hi:
I'm learning about the 60-Degree Pendulum Astrolabe:
https://prc68.com/I/PendulumAstrolabe.shtml
The idea is to mark the time when a known star crosses the 60 degree
elevation circle.
Is there an Android app where I could just push a button and have the
local mean sidereal time recorded?? Lacking LMST is there an app for any
other time scale?
