I am making the biggest LED sign yet. It is 4 feet wide by 2 feet tall. It will feature 72 x 40 Addressable LED's. That is a total of 2880 LED's. This picture shows it next to one of my standard 16 x 72 LED signs.
Since the LED strips are actually made up of sections that are 1/2 meter long they need to be soldered to get 4 feet. That takes two 1/2 meter lengths and then 12 additional LED's.
Here is a big picture of the sign being made.
The LED panel has all of its LED in place now.
They have 40 connectors now on the back side. The LED strips come with shorter wires to the connectors and the connectors I buy come with longer wires.
I need to make wire harnesses to connect to all of the connectors. The harnesses are made in groups of 8 for the 8 data lines from the Arduino.
