so i’m guessing you hid the LED and the batteries (and switches and whatever other electronic parts needed) inside the solid terrain atop the base? or is this something that you are fitting to a display tray so it looks awesome while being shown for judging/viewing?
I work in electronics, so I could have wired up a complete wireless controlled system to turn them all on with a USB remote. They have some LED Candle systems I could have modifed.
But I went an even simplier route with this that I think can easily be done a budget.
I went to the the Dollar store and but LED icicles. They have a 3 small mini batteries like for kids watches inside. To turn it on, one twists the top to close the circuit. It’s very small maybe 1.2 inches. long and I could make it smaller.
I decided to make differenc sizes of terrain, keeping the profile a bit different, not to bring attention to what was powering the bases.
The lave displays are just to show how I combined the two ideas into one. Which also allows me to combine armies.
