A while back I found these cool old display tubes (known as “nixie tubes”) that show scientific symbols. I finally got around to building a little robot that uses the “volts” and “ohms” symbols as though they were different stages of eyes during a “blink”. Hence his name. There is a home made cam mechanism in his head that causes them to switch back and forth.
