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!

So is that the “Weeping Angel” clock?

Where does someone completely new to Arduino/electronics get started with a project like this? How do you know what signals to send?

There are no signals, you just have to switch on and off an electromagnet.

Thanks!

Buy an Arduino kit; start here: https://learn.adafruit.com/series/learn-arduino

Thank you!

That’s excellent! Do you have a video? I would love to see it in action.

[hcs]

By design it can never be seen in action ;)

xD

[dariferrari]

Sounds super cool! I’m also interested in how exactly you did it

[crackercrews]

What a cool idea. It's like the sun from Super Mario.

is the source code for this on the web?
