Hollow Clock 4 Remix

This clock is a remix of Hollow Clock 4, one of the amazing designs by Shiura. I prefer the narrow-beam look of this design over his improved Hollow Clock V. In this remix, I have incorporated what I liked best from both designs and added some of my own improvements. I also designed optional improved electronics with significantly greater timekeeping accuracy and no humming noise when the motor moves the clock hands. See end of these instructions for details.
