The Self-Writing Clock

I first proposed the "Time-writing Clock," a clock that writes numbers and displays the time, in 2016. The Time-writing Clock uses the power of weights to write and update the time every minute. The work utilizes a completely new mechanism for a clock, where a magnetic board is used to display and modify the time and requires overcoming a number of technical issues. In this challenge, the goal is to utilize "Kakuri" technology to help provide a long term solution to the number of mechanisms found in the clock (such as, power, writing, erasing, etc.) The self-writing clock aims to use no electricity at all in the future.
