@MainLine Steam posted:Thank you very much. I have been pondering minimizing the number of center rollers per consist so interconnecting LED boards between cars. As discussed with you some time ago this would significantly reduce track generated noise. I Run conventional so it could also help slightly with "block bridging".
Think it might be in order to wire up a few cars to determine light output desired. Plan on using 5V LED boards. At that point measure resistance across trim pot. Then adjust components so I could power (3) 18 inch cars. The consists I have are 15 and 18 inch cars. Plan on using a pair of 1000uF caps to reduce flicker. (Cheaper than a 2000uF). Please let know if that makes sense to you. Thanks.
You could also just run track voltage on the tether and then you can put a module in each car.
It's also quite possible to build a module with more current output, I just didn't do that. 
You could put a AC-DC buck converter in one car, set it's voltage to say 6 volts, and then use a resistor in each car to set the brightness. If you want more bulk capacitance, you add it to the filter caps on the buck converter module.
