2 tactile switches to access all the available functions.

3 linear potentiometers that was a resistance between 1K and 20K.

Alternatively, you can use a pcb and solder on the pixelleds yourself.( Preferable option! ).

Pixelled strips of 144 leds per meter.

ESP32, I used DOIT devkit 1.0 but most ESP32 board will do the job.

Furthermore, programming the ESP32 can be done with the well known Arduino IDE.Ī complete and extended building manual can be found at instructables

Therefore, I also included a IoT webserver to display the result of the analyzer. I know this board is way to smart and has processor power beyond what is needed for this project. The Pixelleds are controlled by an ESP32. The end result is a 10 channel spectrum analyzer with a antique look that can easily be modified to fit a steampunk theme.Īlthough the tubes I created look like Nixie Tube's (IN-9/IN-13), they are larger in size and they can display multi colors. I created my own tubes using testtubes, fly screen fabric and PixelLeds like WS2812bĪfter making the tubes, I use a lasercutter to create wooden panels for a housing to place the tubes on. This is my version of a NIXIE tube lookalike Spectrum Analyzer
