Reverse Clock

An intriguing mechanism in which numbers rotate while a single arrow serves as its lone hand. To read this clock, start from the inner circle and move outward, directly above the 12 o'clock position - an assumption, albeit a reasonable one. I've included a photograph of a motor that matches the exact dimensions of a similar motor I purchased locally at Michaels for use in this device. Due to cropping issues, some details are missing; however, it can be found for under $10 on a popular online shopping platform. The hour circle was initially intended to frictionally attach to the white plastic area of the clock motor where the hour hand would normally connect. However, I ended up needing to use glue to secure it properly without it falling off. Be cautious not to get any glue on other parts of the motor stem, as this will prevent the clock from turning. It is essential to align the hour hand with the 12 o'clock position when gluing it down, as the minute hand can only be attached in one specific way. If improperly aligned, the minute hand may appear to be at the top of the hour, while the hour circle displays a time that does not match. After observing this clock for a couple of days, it might be wise to glue the minute hand into place as well. Install the AA battery, set the clock's time, and then insert the clock motor into the square opening with the proper time aligning with the arrow on top. The friction should hold everything securely in place. Make sure to set the time before inserting the motor into the hole, as it cannot be adjusted once it is in place and may require some effort to remove. Once the clock is installed, insert the stand's stubby ends into the clock where the two square holes are located. If the motor does not hold securely enough or wobbles due to looser tolerances, there are tabs on the back of the clock face that can be used as a printed "latch" to secure it in place. I did not need this feature myself, so it was omitted from the final design, but it should be relatively easy to print. It is worth noting that these plastic pieces are significantly heavier than their lightweight counterparts, which were intended for use with clocks. As a result, I cannot guarantee how long the battery or internal clock gears will last. Good luck, and thank you for taking an interest in this project!
