Hardware Specs 11.14

The display is pretty much spec'ed out. 64 red SMT LEDs in a high density configuration being turned on and off by 8 latches driven by a microscopic ATMEGA32 that sucks a 2 bit intensity value for each pixel out of a small EEPROM chip that is, just like its peers, connected to a 3-layers vinyl-cut circuit board held on a laser-cut transparent acrylic substrate and before I forget, the light diffusers utterly rock.

Here are some snapshots of the (now discarded) acrylic board:
