Since we started modding the Master System 2 on the previous post, I thought I should go ahead and fix another omission of the system. A freaking power led! How would you know when the system is on without one? Well, that’s an easy fix but, since I already mentioned in the previous post that I don’t like modifying these old consoles in a irreversible way, I decided to go the extra mile and 3d print a new power button with the necessary space to let a led shine through it, so I could save the original part.

So first thing is first. I already had a bunch of color cycling 5mm leds lying around from my NES mod, so I decided to use one of these as my power led for the SMS2. These are quite fun, since they automatically cycle through many different colors when power is applied.
The way you connect the led is by using 2 pins of this little thingy (which is a Voltage Regulator), which is accessible inside the Master System 2 even without removing the metal shield:
The led fits nicely inside the 3d printed power button that replaced the original one and the pins and wire come out of the side, so it does not affect its usage which is to actually, well, power the system on and on by flipping the switch below it.
And that is all you need to do. Here is a video of the result, in real life it does not shine so brightly and it looks very nice when powered on.
