The physical development of Change Counts has not started yet, but the bill of materials, schematics, and black diagrams have been made to begin the process. Before building Change Counts, we will be testing the equipment through a series of demos. For example, with the LDC1000, we will first program it to detect coins and profile them. Instead of integrating all the pieces together at the beginning, we will run each part separately to ensure everything is working smoothly. This will also help us find the roots of problems quicker because if everything was put together and it was not working, it would be harder to figure out which part had the issue and why it was happening.
