With a 12K resistor, the nixie current works out to between 5 and 7mA, by quick-n-dirty calculations. Which is okay for your mux'd operation. An OG3 runs just at about 1mA. The big current hog is that IN9 bargraph, which will pull 12mA full scale. That's why you notice the change on the dekatron. Why not try a IN13 bargraph instead ? It only draws 4.5mA full scale. The color is different. That might be a personal preference. I can't dictate your personal taste, that's what wive's are for. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
