Don't Fart on A Camera: Make a ring light from a plastic cake lid

I was saying to myself the other day, "you know I'm gonna get down on it and make a ring light sometime here..." or something like that. Well despite how I thought it to myself, I did get around to making a ring light. Its almost finished, just need some transparent white stuff to cover the ring.

Components.
- A type of plastic lid. I used a cake dish lid from some grocery store bakery cake.
-Exacto knife
-something tubular or cylindrical to block the flash from the lens
-white spray paint (flat)
-Reflective duct tape
-some white transparent material to soften the flash
-duct tape
-White trash bag or something of similar properties that will diffuse the light
To build:
Firstly I spray painted the inside of the lid white.

I used a almost finished roll of gray duct tape to trace out the center circle that the lens will protrude into. I just marked the center of the dish, then eyeballed (guessed) where it was centered. I used the almost finished duct tape roll for tracing the outline.

Originally I cut the flash hole in the back of the dish, but I changed that location to the lip of the lid so that there is more light dispersion. I taped the bottom and half of the lip with reflective duct tape.
For the center hole, I just grabbed two disposable cups and cut them (to make two pieces)so that they were cylindrical like then taped them into the lens whole.

At this point its nearly finished, you could modify it here for your liking.

All the photos in this post were shot with the lens through the center of the ring flash, except for the one that' devoid of color and the flash is off to the side.

EDIT: So I topped all this off by covering the ring light recessed area with a white trash bag, and finally I taped off some of the inside diameter of the ring, effectively narrowing the area that the light will come through. At this point I think the project is finished. There are other DIY ring light projects out there, so if this doesn't seem your bag, fret not.
