In 28mm?! That’d be pretty tricky.

The smallest LEDs I’ve hand soldered are 0603 but realistically, anything smaller than 0805 is near impossible (by hand). You’d probably only get three in a row (so less of a Larson Scanner effect, more like an animated left-right blinky led!)

It’s tempting to give it a try, just to see if it’s possible/feasible. But everything is telling me it’s not!

At 54mm you *might* get away with a 5 LED larson scanner (5 x 0805-sized LEDs, if not 5 x 0603). But that’d be a tonne of wiring and a whole heap of aggro!
