I don't think that multiplexing is a bad idea.. On the contrary, it should extend the life (provided that you don't drive the tubes at more current than they are rated for). That's the key, really.. I think that most people drive the tubes at significantly higher than rated currents when they multiplex so that the brightness is higher.
If I run 6 IN-12 nixies at 2.5ma each in a 1x6 mus, then I would assume that the tubes would last 6x as long as they would in a direct-drive configuration. -Adam On Wed, Sep 19, 2012 at 6:39 PM, dr pepper <[email protected]>wrote: > So why is multiplexing a bad idea, and static displays make tubes last > longer?, does multiplexing accelerate cathode poisoning or something? > I have 3 or 4 prototypes I've put together and they all use > multiplxing, even the single tube ones use pwm as a brightness control > (and so probably inherit the 'bad habits' too). > > -- > You received this message because you are subscribed to the Google Groups > "neonixie-l" group. > To post to this group, send an email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit https://groups.google.com/groups/opt_out. > > > -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
