Ah good questions.
First, it will run off 5-15v AC or DC. So yes, some kind of wall wart would be fine for a fixed blinker.
The board is “expensive” for a fixed application due to the super capacitor. It’s job is to deal with dirty track, plastic frogs, etc. it’s not necessary for a wall powered application. It would be easy to make one without it though.
As for multiple LEDs, yes, it could drive more than one. The problem here is I’ve built the resistor into the board to make it easier for a FRED. That would need to be removed for multiple LEDs so correct external ones could be added. So probably not good for multiple LEDs.
There’s no reason I couldn’t make a larger board suitable to drive multiple LEDs with small variable resistors so the user could adjust the flash rate and even dual outputs for like a crossing signal pair of lights. But my thinking is various other folks fill that niche. Just plug is a great structure system. Circutron makes a number of cool little boards.
I just wanted a bettter FRED. The firefly one is quit good and fairly priced. There are a couple of other options that are ok, if you like bending wipers and adjusting trucks. I thought if I could make a better board and use Kato caboose trucks to get needle point pickup it would be a better solution for me, and maybe I can hook up a few people on here along the way.
