gunrunnerjohn posted:Obviously, any type of indication that the wheels are turning will do the trick for the spark enable signal. I'd be thinking of something a lot more random than a periodic timer pulse for the sparking that will not really look that realistic. I'd consider something like the flickering LED's in blue or white (or a combination of those) to generate the "sparks".
Perhaps an even better solution is the ngineering.com lighting effects modules. https://www.ngineering.com/lig...amp;%20highways.htm, about halfway down the page.
I didn't even think of using this. I'll take a look at it. I take it one board per car?
