After buying some mini LED light strings for decorating, I was left with a number of their "Try Me" circuits. These are comprised of a push "On" button wired to a battery case with three 1.5v LR44 batteries which is in turn wired to a connector. I am thinking that these things might be good for something in our modeling, yet, I have no idea what it would be.
Do any of you folks have some thoughts?
