Populating the panelsSo all of my panels are dry and ready for switches, etc. This is about as straightforward a step as you can get. Simply put each switch / device into its opening. All the arcade switches, toggle switches, and rotary potentiometers and switches have nuts to hold them in place. Just use them, it's that simple. You'll want to cut out the opening through the transparencies first, of course. I've currently left all the transparencies intact over the 7 segment and bargraph LEDs. I may leave them that way for a neater appearance, if it doesn't interfere with the LED appearance.
I've also noticed that as I glued the transparencies to the cutting board for the status lamps, the cutting boards were warping significantly. We'll see if I can correct that as it cures. If not, I'm going to leave the transparency across the opening intact and simply sandwich the cutting board and the label transparency between this outer transparency and the printed LED matrix holders.
Now is also a prime opportunity to switch the LEDs in the square arcade switches - these come as white LEDs, but you'll probably want to change the color. I've settled on using a 5 mm diffused red LED in the master alarm and the abort switches. The switches in the mission sequence panel I'm populating with 5 mm diffused blue LEDs.
Switching out these LEDs is pretty easy, but I'll step through the process. First, remove the switch and LED from the back - just a slight turn and its out.
Now pull the LED and its holder straight out from the switch.
And voila! The switch now lights up a nice, blindingly bright blue...
