Time machines. Part I

Time.



Why does it exist?
Where did it come from?
Why do we measure it?
So precise?

Anyway.
I want to measure it too.
Build a machine to measure it.
Watch it, show it.
Passing.
Flowing.

Understand it?
No.

Just build a time measuring machine.

Or 2...
Huygens, pendulum, weight, movement.
Problems.
Gears...
Very complicated.
Drew something up...



That should work, I think.
Have a pendulum.
Make it out of Quartz so you get rid of all temperature problems at once.
Luckily there is one of the last quartz factories in Switzerland.

Make the blob.
A friend of mine has a lathe.



and make some more parts.



Connection things to fix the blob to the quartz rod.
Fine adjustment blobbies..
A big solid threaded cylinder to close it all.



And it looks cool too!
Now had to find a frictionless system to fix it to something solid.
Like a house or so... or a mountain...



Used some very thin stainless steel.
Cut it out with a water jet



And the holder



That did it.

Adjust the whole lot to the local gravity.
I calculated g at 9.805613002
Now just detect the movement of the blob.
Use that signal to count seconds.
And if the amplitude gets too small, pull a bit with a magnet.








It works!
I can see seconds!
Count them too.
Can't tell the time yet.
Does it matter?


Long time no time....

Had to find a cool way to show the measured units.
And calculate to indicate comprehensible sub measures.

Seconds........................................................
Minutes..........................................................
Hours.......................
Russian NIXIES.


Then mount the whole lot on a nice oak cabinet.
With the electronics hidden behind.
And the wires too. A lot of wires....

Pendulum holder

Magnet with second counter...


And it works!!!!
Beautifully!!
next clock.
There is more time to measure!

I actuallly know this guy!

Wouldn't know he was so damned smart unless you have seen some of the things he has done like this clock!

Looks and is great. Neat piece of design etc.
Howzabout making a clock that measures the biological life span of a dog ? It could tell you how old your favourite pet is and exactly when his birthday is. Imagine: 7 B'days per year for Tibo. All those cakes and special collars sold by the pet industry multiplied by seven. Not to count the dogs esteem for you... Sell it to Whiskas ...
