Quote from: madbean on August 19, 2018, 02:27:51 PMWhat I was thinking of doing was to drill a hole in the enclosure where the donut is going to go, and putting an LED inside the enclosure so it shines onto some Lambertian (i.e., diffusely reflective, like a white piece of paper) surface at the bottom of the hole, giving a subtle glowing effect. Regardless of whether that works, I'm drilling a big hole under the donut.
A big fat 8mm LED in the donut hole would make this even more exceptional.
