DIY WE: dot-matrix display out of bottle caps (MAX7219)

Last Weekend was dedicated to building a simple dot Matrix display out of whitle plastic bottle caps for the frame. I glued the caps together to build 8x8 dot matrix then wired the 3mm green LEDs in place. The LEDs matrix is driven by a MAX7219 module. The Arduino library (MaxMatrix) can be found here.
