Projection Clocks

Sunday, March 14th, 2010

The two clocks in this video have been around for as long as I can remember, and then they kind of disappeared. I found both of them recently, sitting in the darkness of my grandfather’s seldom-used workshop in his basement.

I’d love to know approximately how old they are. They can’t be all that old, but I know they were around when I was very young–so I’d guess they are from sometime in the 1980s.

These clocks use a simple flashlight bulb for their projection, and run it at lower than its rated voltage to prolong bulb life and reduce heat output, which is important considering that the entire projection unit is plastic like the rest of the clock.

Both projection bulbs were burned out, both clocks had loose power plugs on them and corroded battery terminals. The more used looking of the two clocks actually had developed an internal short as the litz wire going to the power plug and battery areas had been twisted around and around until it shorted things out.
