How to Vol 1: Make a Ring Light

Line the inside of the medium bowl and outside of the small bowl with reflective tape and bond them together

Glue the drain fitting on the lip of the small bowl

If you want to attach the ring to your camera for hands free shooting, glue the appropriate hood on the inner lip of the drain fitting

Fashion a disposable cutting board to the outside of the entire ring if you would like a bit of diffusion

Attach the lens hood to your camera and enjoy your new device

note:  With very little frugality  I was able to complete this entire system for $13, the largest cost being the drain fitting.
