Jordan,
these look great. I've been making something similar for my own trains for
awhile. Are yours constant output style? Or does the output vary with the
voltage supply? It's funny, but this was something I pursued when I first got
into LEGO trains back in 1990, but the lack of 3v regulators on ready supply and
white LEDs was a bit of a problem. I recently switched to a constant current
type circuit that regulates each LED at 17ma, good for single diode directional
lights. But I've had also had good success with a constant voltage (3.3v), good
for non directional lighting. I add a supercap to the later, which keeps a pair
of LEDs lit for over a minute after the power is cut.
I bought a couple of LED Christmas light strands last years, and harvest the
LEDs as needed. But these are the blue-white type, are you using golden white?
I'm very interested in your circuit board power pickup. Did you develope theses?
I'd love to get a dozen of these, with or without the wires.
I have no interest in selling light sets myself, but I'd be happy to discuse
ideas. Do you plan to offer 3mm LEDs as well?

First, I should mention that I know LEGO train fans are often quite electronically-savvy and have developed their own lighting kits in some cases. I am hoping to reach (...)
