I’ve chosen the LED displays, found a matrix driver, and determined the final positions for each LED display on the faceplate. The next step in the time circuits project is to build a dedicated circuit board for each display. This process starts with creating an electrical schematic.
I’ve figured out what LED displays I’m going to use and I’ve found the case they’re going to fit in, but before I can design a custom circuit board I need to figure-out how they’re going to be spaced in the enclosure.
Before I can start designing the time circuit display circuit board, I need to figure-out its outer dimensions, mounting method, and the exact positions of the LED displays. This starts with the enclosure the circuit board is going in: an LMB Heeger Crown Royal series #852.
Now that I know exactly what I’m looking for, it’s time to buckle down and try to find some real-world LED displays for the time circuits.
Now that I have a tentative plan for how I’m going to control all 300-some LED segments, the next step towards making this prop a reality is to figure-out the specifications for the LED displays.
I have no formal education as an electrical engineer, so one of my first steps for the time circuits project is figuring out how to drive the large number of LED segments that make up the three time circuit displays.
I have a thousand and one little projects and project ideas floating around at any given time, but there’s been one thing I’ve always wanted to build: a replica of the ‘Time Circuits’ from the Back to the Future movies.
