This is so simple and prolly has been done a bunch, but I thought it was cool.
I moded every dongle I could find. I still had two stock non-transparent controller dongles left over. So, I just cut a hole in the top and made it glow.
First I just put a purple LED and resistor in.
Then I cut a hole out of the top of the dongle head.
Then I filled it with hot glue and let it sit. Then I sanded it down… and walla.
it is not sanded down all the way, and if I tried to be a bit more careful I would not need to canded it. The lights are actually deep purple, but the digital camera make them seem bright blue. So, it is not as bright as it looks at all.
I am going to over fill the other one I have and press a round cap down over it. This will form the glue into a shape. I was thinking of am “X” shape… that would be cool.
