Day 11: Thing 11 — led arrays

Today I got 2000 little leds in the mail.

They are really bright. So of course I had to play around with them. I made 2 8×8 arrays one is made of magnet wire with no supporting background. I will figure out if I am going to mount this on somehting later. In the mean time I built one on a perf board. Both took for EVER to make. The one on the perfboard is wired to a maxim 7219 led driver to be driven by an arduino.
