I wanted to start a discussion about constant current sources (as opposed to sinks, because I want to provide a constant current to the anode regardless of which cathode is pulled to ground). I've found many articles on the web. Some for Nixie constant current sinks, some for LED constant current sources, some more theoretical, some very simple, some very complex. But no constant current *sources *for Nixies - i.e. designs for a constant current source that include actual part numbers and component values. I wanted to start simple, to make sure I have at least some grasp of this topic, so here is my first stab. I would be grateful if anyone could let me know if it would work as is or if I have made some fundamental errors - ignoring improvements such as temperature stability for now (BTW R3 is Re in the equations).
Be gentle - this is all new to me! <https://lh3.googleusercontent.com/-6_6C5llpeLk/WNXifCYtvXI/AAAAAAAAAg8/oXiVHkDrr8YlvZAji94FgfB9zsarvo-xgCLcB/s1600/CCS.jpg> -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
