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! I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, eevblog and others. You can do the same using an ESP32: https://github.com/aknik/ESP32/tree/m... 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.
