This Nixie based looking clock is absolutely amazing. What you see are not real Nixie tubes but tubes of my own creation. It uses pixelleds that where fitted into a glass laboratory tube. The electronics is using a pure analog design to isolate all the different frequency bands. No need for hard to find IC’s and no FFT. The ESP32 is used to process the analog data into visible bars. ( Pixelleds)

With age, soldering is becoming harder and harder on the eyes. I good microscope for soldering is an absolute must have and I don’t have one yet. If you have an idea on a good one or you want me to try one, please contact me.
