DIY Device that Monitors the Power Grid of the Entire Country

The power grid is one of the most critical systems in our modern world, but we often take it for granted until it fails. In this video, we show you how to monitor the power grid of the entire country with a simple device. Using an ESP8266 board and an optocoupler, we measure the oscillations in the power grid and calculate its frequency with high precision. We take you step by step through the process of building the circuit and testing it, also we provide the code for programming the ESP8266. With the help of a slow-motion camera, we demonstrate the fascinating property of frequency synchronization in the power grid. This video is a must-watch for anyone interested in electronics, energy systems, and the power grid.
The code for the project and the list of components can be found here:

Nice project! Glad that you update your videos again!

[@carolineb3712]

Great video!

[@wappogallo3503]

All Your work is awesome man! Thank you 👏👍

[@Romanticgeeek]

Your content is original and always clearly explained 🙏 I love the fact that the speakers will be in sync even if they are located in different parts of the country as long as they are connected to the same power grid 💫

Thanks for sharing

[@Ruthlesslybloodyminded]

That’s cool!

[@colossalbigfoot256]

Pretty dang cool dude. I need to understand electronic circuitry more.

[@williamvaughan1218]

I would buy one of those.

Where we get more details about this project in complete detail with theory

3:15 My experience shows that it is not really necessary to limit the reverse voltage. I used a similar circuit in one of my projects (music player for an elevator) and I just connected optocouplers through some resistors to the mains. I used 4N35 optocouplers and they worked just fine.

Thanks for some really interesting content !! Much appreciated, and we think of you in these terrible times. I would like to support you. How do we get in touch?

[@elarcadenoah9000]

cool

[@thefishguy1241]

Dosen't the speaker blow up at 220v ?

[@ejazali200]

Can i get the code of the project

[@jackwillard9147]

❤😊❤

You have provided an excellent technical explanation. I hope frequency stops fluctuating over there very soon. Slava Ukraina!

In my case it would just be Texas the best country on the planet.
