A little update on my automotive gauge project. These past weeks I've been to busy to finish them up, but I got a chance today to play with how to diffuse light. So right now there is a 1mm thick spacer that has everything engraved over the LED's. This spacer has the engravings filled with white epoxy. And now I'm waiting for the last part to arrive, the smoked black glass for the finishing touch. So hopefully when the gauge is off, you won't be able to see anything else than a gloss black front.
Back with more updates soon!
