The DC powers supply, as shown previously, got made at this point in the build.
Making the printed circuit boards (PCB)
Testing the 24, 12, and 5 volt outputs.
Since the console will now include an interior diorama, I added a small PCB for a 'blown fuse indicator'. The green LED indicates all is well, but if the red LED turns on instead, it means that it's fuse has blown. Below right, the whole DC power supply got installed into the console.
