Question 1. Has anyone tried paralleling two or three Nixies from a single 74141? I am making a working demonstration with a variety of vintage displays (Nixie, Dekatron, Numitron, Amperex 8453,etc) that will all count together from a common clock. Question 2. The data sheet for the IN16 says: 8. If the indicator is used in such a place that it is not being affected by other sources of light and the effect of the surrounding energy sources is lessened due to the indicator being encased in a metal capsule, in order to avoid the possible increase in the voltage and the ready-time of the indicator (the time it takes for the indicator to display the digits), it is recommended that you use artificial lighting with a luminosity level of not less than 40 lumens or one of the “comma” symbols as a “pilot” electrode with a current in its circuit of 0.7—1.5 μΑ. which helps explain a question about Nixies that do not fire in the dark. What can be done for tubes that do not provide these commas for keep alive current (beside shining a light on them). Can a very high resistor from one cathode be used?
Question 3. Another section talks about biasing idle cathodes. 7. In order to eliminate the glowing halo on idle cathodes, it is recommended that you provide them with a voltage of plus 60—110 V relative to the cathode used (indicated). Is this what the 60v zeners in the 74141 do? Are pullups required? I need some practical tips on connecting the tubes without making the circuit too complicated. The 74141 alone seems to work well with the IN16 without biasing the comma. [image: Nixie driver.JPG] -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
