CircuitSetup exclusive! These time circuits displays are made to the exact sizes, and spacing of the time circuits that were originally in the A-Car Time Machine Delorean in Back to the Future. In these displays the 3 character month is replaced by a 2 numerical digits. They feature our custom 7 segment displays in Red, Green, and Yellow.

Note: the colors are more vibrant in person due to the nature of multiplexing and camera shutter speed.

The housings can be 3d printed, and the stl files are located here.
