Oh, light clocks are not difficult to build.
You can take a fiber optic transceiver and a mirror and a bit of
electronics.

Do a little optical impedance matching to free space and set up your mirror
at a convenient distance.
Set the electronics so that every time a tick is received, a new tick is
launched.
Press the little 'starter' button.
You have a light clock.

Any high school kid can build one.

The real trick is to build a 'normal clock' that ACTS like sue says a
'normal clock' should act.

Have you read the chapter is SR about Fizeau's experiment?
Do you know how to use vector addiion to compute the
round trip of an aeroplane?

You and Dave still seem unfamilar with this material.

Do you know how to use it to compute how much a light-clock slows?
