A remotely controlled, precise analog wall clock like that one from IKEA is a cool thing. Today we will build our own remote control for such analog and digital clocks. All we need is a Raspberry Pi and a few electronic components. And we will learn something about resonance frequencies, capacitors, and ferrite antennas. Let's hack!
In this video, we will:
- Learn how radio-controlled clocks work
- We will build a ferrite antenna for receiving and transmitting time signals
- We will test and optimize it
- We will install software on our Raspberry Pi to create signals for DCF77, WWVB, MSF, and JJY
In the end, I should have a precise time in my lab. Even if it is in the basement
