“In a previous Instructable (Microbit Binary Clock), the project was ideal as a portable desktop appliance as the display was quite small.
It therefore seemed appropriate that the next version should be a mantel or wall mounted version but much bigger.
There would be no need to reconstruct another controller but to use the existing clock and add an interface for the display.
This Instructable details the process of creating the BigBit display and the software updates to the existing clock.
