Nice!
If you're already using an ESP32, you can do all the signal processing on it, and get rid of all the filtering and MUX components. Can use FFT or Goertzel filter array in software.

Yes been there done that…I build several units with FFT but I wanted something else this time. On my own channel @theelectronicengineer you can find several fft analyzers\
Since when a micro controller counts as discrete electronics?

The microcontroller is used to drive the leds but the actual frequency analysis of the input signal is done using discrete components. Opamp band filters to be exact

@@TheElectronicEngineer ok, since when any kind of IC counts as discrete component?
I thought this video was clickbait. I was pleasantly surprised! Edit: Level your microscope so you can sit comfortably and use it. For a long time I used my scope just like you, but it was painful and annoying. A friend who works in biotech suggested correct alignment. I use an Amscope, and had to reconfigure my entire setup to be able to work comfortably under a microscope for long periods of time.

Yes for sure! This was only for video taping. I do have a chair lol
You could almost play Tetris (Тетрис) on it.😁
This project in itself is an Easter Egg!

Aah you discovered it! nice
Awesome 👌
A good video, but it's not a Lego spectrum analyzer; it just uses Lego as the housing.

Yeah it does.
Why do people insist on making words out of acronyms?

I also grit my teeth when I hear someone pronounce the acronym for a Light Emitting Diode the same as element 82. But on the other hand, I don't ever remember anyone speaking the four separate letters of NASA, or NATO.
