Andy Clark of The Workshop Shed blog made this, The Topsy Turvy Clock, after being inspired by a kids TV show, featuring a clock with numbers in the wrong places.
Andy Clark explains:
I saw a clock with the numbers in a Topsy Turvy order and wondered if I could actually make it work. After concluding it would be too much of a technical challenge to make it entirely clockwork, I decided to use stepper motors and software control. I wanted it to look like an original mantel clock so the brass mechanism and style of numerals were key. I had the numbers laser cut in card by a company who normally make wedding table decorations so the what I call "antique white" is actually "champagne". I started planning in late November last year so it's been a long build with mechanical, electronic and software challenges. I finished it just this week after a month of fine tuning and completing the software.
