Use case: Christmas village powered by AA and AAA batteries.

Question: is there any way to automate these items? The only way I can think of a method to do this would be to modify where each items switch is located and wiring in a remote of some sort. But I’m just trying to find a less invasive method if possible, but I’m not holding out a bunch of hope…

    My wife has a bunch of these that all took 3 1.5v batteries, so I soldered wires into them to run back to a “hub” that plugs into a 5v microsd charger and they are switched with a simple outlet remote. It would be a good idea to make them not permanently attached to the hub for when it’s time to put them away.

    You could do it with a mix of 2 and 3 1.5v battery lights but you’ll want to add an appropriate resistor. A 100Ohm resistor should drop it 2v at 20mA. It’s kind of depends on how they’re wired, mine aren’t out yet. I don’t recall if I added a ~25Ohm resistor to the 3 battery ones but I probably should have if there wasn’t one already.
