High Voltage

Nixie Tube Experiments

I recently purchased a set of 12 IN-12A (ИН-12А) nixie tubes from Russia. I was eager to try them out and make sure they survived the trip. For this I built a very basic high voltage power supply to fire them up, and then got a bit carried away! This article concerns the use of a relatively high voltage supply. Stay safe when working with high voltage, and do not proceed until you are comfortable with the required precautions.
