Way back in March (I think) I bought an Arduino to add some flash to this train layout. I played with it for a few days, said "This is going to be cool" and went back to riding my bike.
The problem is that, while the software is obviously going to be easy the mechanics of the assembly isn't - not for me, anyway.
For example, I need to run 8 (up to 16, really) white LEDs out onto the layout, and maybe 4 tri-colors. Took me 2 hours to set up the soldering iron and make a single LED+wire-harness. A lot of that was "find all the junk and get it in one place" time, but still.
Sigh.
