Topsy Turvy Clock Tells Confusing Time

Looking for a new clock but hate the fact that all the numbers are always in the correct order? Look no further than [Andy]’s topsy turvy clock which correctly tells time despite the fact that the numbers on the face of the clock are in random positions.

At first glance, the clock looks fairly normal despite the mixed-up numerals. Upon closer inspection, the clock is much more than it appears to be. A battery backed real-time clock keeps track of time, and a microcontroller turns the hands of the clock to where they need to be. The clock uses optical sensors to make sure the hands are in the correct starting position when it is first powered on.

Check out the video below for a better illustration of what the clock looks like when in operation. The hour hand is always pointing at the correct hour, and the minute hand starts every five minutes at the number it would have started at on a normal clock, i.e. at 1:15 the hour hand will point at “one” and the minute hand will point at “three”.

We love this very interesting and unique take. It was inspired by a few other clocks, including a version of the infamous Vetinari “random tick” clock which will drive you crazy in a different way.

  1. Fun!
    I once changed the dial of a clock by giving it only 10 hours. You can tell the time by just glancing at it. But when you take a closer look you get confused :)

    But this clock is really confusing.
