Well this is interesting... I tried taking the anode control wire of the second digit and tying it to ground. As expected, this turns all the digits off and eliminates all ghosting... except for seven! Seven turns off just like all the other digits, but for some reason it continues to ghost over from the other tube. Even stranger is this:when I measure the second digit's anode voltage compared to ground, my DMM says zero volts (well, a few millivolts). But when the first digit hits seven, the DMM says the anode is 25 volts relative to ground (remember PWM is going on here, so that's probably not accurate, but it still shows there is voltage). As far as I can see, the wiring is exactly the same between all the digits, but seven just keeps acting up more than the others... I probably have some stupid wiring mistake causing the seven thing, but the ghosting still doesn't want to go away. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
