Right! Sorry I meant 1mS. I wanted a 2x3 muxing, but I lack I/O pins, so I will have to stick with this one. As I said, the brightness looks surprisingly bright.
@threeneurons Yeah, something like the B schematic, just that I included the R2. If I remove it, it might completely shut of my nixie, instead of leaving it under 93 volts when "off". It might be the reason for leaking some of the current through the other transistor, to the nixie. I am going to play a bit with your advices, but there is one thing that still bothers me before I continue. Can I or cannot I continue doing these test without the anode resistor? I guess the non-instant turning on isn't really a priority right now. Oh, and off topic; why do I keep getting an error while trying to post a message with a link incluced? That's why I had to chop it with spaces like that. I noticed everyone else posting normally with links, so am I doing something wrong? Thanks everyone, hoping to post my positive results soon!
