Old Elias Ingraham clock
AndreiRS, Mon Apr 16 2018, 11:28PMMy grandpa had this clock while he was alive. It was hanging here on the wall for years, not working. First I thought, I will find a store to rebuilt this clock. Then I just took it from the wall and discovered it had very little problems actually. The clock "hands" or needles were a bit bent and loose. One washer was a bit damaged too. Now it works.

It's always a good feeling to repair something and get it working again.

One project on my to-do list for decades has been to make a precision pendulum clock,
(I intend it to be 1.000000 'ticks' per second
)
last year I bought a pendulum clock via eBay for £5 ... working, including delivery !
After a little cleaning and adjusting (it ran a little slow),
I hung the clock in two different places in the house then finally in my shed,
- because my family did not like the ticking sound, and hated the chimes.
It is now in pieces waiting to be 'modified'
P.S. a bit of trivia :
most pendulum clocks when well adjusted should not go 'Tick-Tock-Tick-Tock-..'
it should be 'Tick-Tick-Tick-Tick ...'

Oh noticed that, when it is way off center it gives a very loud tock and a very small tick.

Fun project: Build a frequency synthesiser using the pendulum as a reference frequency. A magnetic or optical pickup could be input to a 4046 PLL, then with a bunch of dividers your output frequency could be in multiples of .5Hz, up to whatever frequency you desire! Good luck with the loop filter though

my plan was/is to feed the 1 pulse per second from the pendulum system (a simple 'pulse motor')
to the electromagnet in a cheap analog display quartz clock - to display the time.
Due to thermal expansion, which can be
the cycles of the Earth, Moon and Sun, tides etc.
local "g" varies too much to be used as a precision reference,
compared to e.g. a rubidium oscillator.
