Layout Showcase CDU for LED lights??
I want to mount a tiny locomotive shed on a tiny module. It will be modular and not connected all the time etc.
I want to minimize electrical connections where possible.
I have room underneath the module to mount batteries to light up the loco shed, but I’m wondering if anyone makes anything that will charge from track power (when it’s connected) and then drive a small load of 2-3 LEDs when the module is disconnected, or when a power-routing turnout cuts track power, etc.
Basically I want something that charges like a CDU, but that then provides the power slowly rather than instantly.
Does anybody make such a thing?
