#287

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.
