Neutron radiation monitor

I had the good fortune to find some old display panels from a particle collider (technically a synchrotron) and decided to being them back to life. Using an Arduino Nano and the most basic code and the 12 outputs I wired up the indicator LEDs using their giant old school resistors to really limit the current output and make all of the lights turn on. While I wanted an random blinking pattern, I chose to run the same pattern over and over with different times on for each LED. If this panel was installed in real life and I saw this, I’d be concerned, but for home use I figured it would just look cool.
