The Nixie tube, essentially a high voltage numerical display, is a device born out of the mid-20th century and used to display digital information in a (human-)readable format. Today, the Nixie tube has been replaced by more efficient, more durable, and longer-lasting devices, such as LED displays and LCDs. However, for this technical brief, the Nixie tube serves as an excellent visual feedback of the PIC16C782’s ability to generate high voltage from a low voltage source.
