I'm starting my first projector build and I'm curious about power supplies. Hypothetically speaking, If the combined draw of the diodes is 2.5A, how much of a margin should I leave for the rest of the hardware (i.e. galvos, amps, drivers etc)? I do realize that this will vary depending on the products used but I'm hoping someone can give me a ballpark estimate for the average, modest projector. A 3A supply would be sufficient for the the diodes, but what would be a safe estimate for adding in the rest of the components? Thanks -Luke
