Okay, so this is version 2 of my compact binary to seven segment display decoder with piston display. I created the first one to place multiple screens and decoders efficiently next to each other, but upon review I noticed that the display wasn't quite centered on the decoder which makes this difficult. This version has centered the display making the unit perfectly modular. It is 3 or 4 blocks longer, but this is a small trade for the convenience. The unit still operates the same as the last one.
