I'm mainly taking part in LEGO events as part of a Great Ball Contraption exhibit.
Most of the modules I make, and that's true for a lot of other builders, are purely mechanical in nature and driven by a single always-on motor. Since the motors have to run continuously for whole days, we usually connect them to 9V train transformers; which isn't a problem for PF motors thanks to the conversion cables available.
However, since LEGO will eventually phase out PF motors, I'm worried about the future - as there doesn't seem to be plans to provide conversion cables for Powered UP elements.
So, is there another way to somehow connect a Powered Up motor to a mains transformer and have it run continuously?
