These mechanisms are super simple to control: just disconnect the board and use a Raspberry Pi or Arduino to send a pair of signals (+ and -) to make the second hand jump one second.
I did an art project back in 2016 with a $2 IKEA clock with a Raspberry Pi and a camera. I used OpenCV to detect when someone was looking at the clock, and when that happened the hands would stop moving, freezing. When the person looked away the clock would tick at a faster race, until it caught up with the right time. One of my favorite projects!
- crackercrews 5y agoWhat a cool idea. It's like the sun from Super Mario.
- maddyboo 5y agoThat’s excellent! Do you have a video? I would love to see it in action.
- hcs 5y agoBy design it can never be seen in action ;)

- fnord77 5y agois the source code for this on the web?
- tzot 5y agoSo is that the “Weeping Angel” clock?
- dariferrari 5y agoSounds super cool! I’m also interested in how exactly you did it
- sam98brown 5y agoWhere does someone completely new to Arduino/electronics get started with a project like this? How do you know what signals to send?

- ProZsolt 5y agoThere are no signals, you just have to switch on and off an electromagnet. Here you can find everything you need: https://www.cibomahto.com/2008/03/controlling-a-clock-with-an-arduino/ https://www.cibomahto.com/2008/03/controlling-a-clock-with-a...
