First of all, thanks for accepting me to the group! I've built a functioning nixie clock that uses a nixie driver to multiplex all six numbers. Due to my inexperience, I just figured out the resistor that I needed to drive a single nixie tube at the correct voltage an current, which landed me at 22kOhms. However, as I'm sure you all know, my numbers were much dimmer once i got the multiplexed clock working with the same 22k resistors. Because of this, I decided to check the voltage drop and current of my nixies and got some numbers that can't be correct, as it is below the operating specs of the tube. Is it some sort of average or something?
I've seen another thread on here where this is mentioned and I learned that I could get a more accurate reading of voltage and current using a scope (which I don't have). What I'm wondering is, is there a way to calculate what the current should be without measuring it? I'm not horribly dissapointed that the numbers are dimmer than driving a single tube, but I'd like to make sure I'm operating at the nominal current in order to maximize my brightness without significantly decreasing the expected life of the tubes. Any help is greatly appreciated! Below is a picture of my anode driving transistor circuit (?) not sure what the best way to word that is. <https://lh3.googleusercontent.com/-Pw6L5BQQbpU/WTS8TDyz4QI/AAAAAAAAAWs/-k91FOy1jiEE3Dirye3vQ5PH8oK1_ugLwCLcB/s1600/Capture.JPG> -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
