Not content with a clock mechanism that was 12 studs wide, I completely
redesigned the reduction geartrain yesterday, resulting in a mechanism that is
only 8 studs wide. There is much less friction in this new design than in the
previous one, so it runs much more easily and at lower voltage levels. I
haven’t tuned this one at all, so it is running a bit fast at the moment.
Now if I can just get that ticking sound out of my head...

I’ve spent the past few days refining the design of my
Technic clock. I’ve managed to
convert it to electric drive (using a 9V micro motor) which enabled me to get
rid of the 2-lb. weight and string. This made it possible to further reduce
the size of the timekeeping mechanism while greatly improving its
reliability. The result is a fully functional electric clock made from 100%
unmodified LEGO parts.
The clock stands about 17 inches tall, and can be powered from a train
regulator or a battery box. Without the dangling weight, this MOC can easily
stand on the mantlepiece without fear that it will take a sudden plunge to
the floor.
I’m still tweaking the timing, but it is already able to keep time within a
few minutes per hour, and has run for several hours at a stretch with no
human intervention. As an added bonus, the clock time can be set (even while
the clock is running) simply by turning the hands to the desired time.
Must sleep now...
