It took almost a year, but I've finally got those I2C LED driver boards built and tested (driven by an rpi). 16 individually-dimmable LED channels per board.
Looks like it should work fine. You'll probably want to insert tabs between your pieces when you run it through CAM so they don't start flapping about, but that's easy enough.
Some of them show up quite faint, for some reason. Those are vias I had to place manually, probably the snap grid kept them from being "actually" connected, but it should (hopefully) be fine when manufactured. All the copper is in the right place.

Long time since the last update. I blew up the arduino when I shorted coil power into the switch matrix while soldering something under the playfield (d'oh!), and I haven't gotten much done construction-wise since then. Instead, I've decided to go back to the drawing board a little bit and build a m...
