The droid controller has a spot on it where a red LED lights up every time a button is pressed. It has space for a second LED next to it, but it's not used for anything. I decided this should be changed and decided to add a green LED power indicator so I know when the controller is on (and to turn it off). To make it more visually interesting, I wanted to wire it in such a way that the green LED would turn off while a button is being pressed and the red LED turns on.
I started filming my work on this, including developing the circuit schematic, choosing the right LED, the right transistor, the right resistors, and so on. The end result was an LED that would light up and draw under 1mA of current, bright enough to see, but not enough power that it'll drain the batteries by being on all the time.
I shared the initial design to the #makerspace channel on the Star Wars: Galaxy's Edge discord server. There it was pointed out to me that the microcontroller used in the droid controller could probably sink the 1mA of current for the green LED and the addition of a PNP transistor was overkill. Removing the transistor also greatly simplified the wiring.
Seeing as how everything I had filmed up to that moment was pointless, I stopped filming and focused on making the mod. This video is a review of that mod.
