One of the forum members experimented (installed?) an LED (I want to say it was a 7-segment LED display but I could be wrong) behind laminate. If the LED was off, it wasn't visible. Turn the LED on and the laminate was thin enough to allow the light through.
I was almost positive it was somunny's
ARK Project but nothing in the thread mentions this. In retrospect it would make sense, somunny is using metal foil.
I'm about 95% certain it was a
table top cocktail type cabinet but I just can't find it.
Does anyone remember who did this and what project they did it on?
edit: corrected terminology.
