Yeah, that's too much voltage, the filament wouldn't have lasted very long at that voltage. > Then I corrected the voltage (to 1.5v): > > http://www.movius.com.ar/vars/elec/vfd2.jpg > > I think the digit is brighter in picture one but the filament as > orange :S Looks good. > What is the difference of sourcing 1.5v to the filament and using > softstart psu that sources from 0.6v to 1.5v ? (like the example I've > mentioned) The softstart just warms up the filament more slowly, which might increase tube life a little. It's a somewhat complicated approach, but if you already have it, you may as well use it. I generally just use a higher voltage supply and a series resistor to provide the proper filament voltage and current. This way, the resistor limits the current surge from the cold (low resistance filament), just using a single component (the resistor). The next thing I would try is using a pair of transistors to let your Arduino turn a segment on and off. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
