So, I have this hair brained idea. What if I could take the multi-color mini micro LED string and add them to a building, train car, or engine? Saves on hundreds of dollars. Most use about 4.5 volts DC to operate. There is 40 LEDS in about 13 ft (4 meters). This works out to be about 3" apart for the LEDs. Now here's the rub, These LEDs are too far apart for O gauge use. What if I tripled the strands and twisted them together to get about 1 LED per inch? Use a voltage rectifier/reducer from 15V down to 3-5 volts.
Can some one please measure their MTH engine or cars and see what the spacing of the LEDs are?
I don't think I can get the LEDs any closer together.
