I thought I would start a new thread for this. I want to build a shift counter using a nixie tube on my custom dashboard. For those of you not familiar with nixie tubes, they are old technology whereby each numeral is lit up inside a vacuum tube individually. They give a cool retro look and glow a wonderful amber color when lit.
I am seeking advice from the numerous electronics experts on the forum. My intention is to use a BEP 3.0 for the output for the shift counter. The BEP has separate outputs for each gear that go to ground and a dedicated power supply (CC).
First off my research has led me thus far; I know I need an up converter to take the 12v DC power supply, (CC on the BEP) to 170v and a 20 to 22k resistor between the up converter and the nixie tube to power it. After this I have concerns, when the circuit is connected to the nixie tube and grounded by the BEP to complete the circuit will the 170v current damage the BEP? Do I need to convert the current coming from the nixie tube down to 12v again with some kind of resistor?
