took a little while (day job gets in the way!) but here's what I ended up with..
still have to finish my table assembly but the building blocks are nearly done
I have hand assembled about 120 modules, they still need some wiring but
all work like my original video above.

front and back of the module, each is 1"x1" square


a small pile of assembled modules, smt assembly really goes quickly, using a toaster to reflow the pcb's. only wish I had a pick & place machine.


cnc'd some frosted acrylic to make individual tiles, which will become the tabletop..
