I wanted to make some repulsor lights for the palm of my Iron Man gloves. I also wanted to do it on a tight budget. What I found was a bike light at Big Lots for $2 a piece. I got a bunch of them because they were fairly cheap, super compact, and bright.
I dismantled the lights to be even smaller and bent the lights to point the other way. I wanted to have the button facing outward in my palm.
I found a chunk of nylon plastic that I cut and sanded into a pair of discs. I drilled holes in the bottom for the LEDs.
The whole assembly fits comfortably into my falm with the glove in place.
