Tip to mechanically reduce brightness of Blinkt! board


If, like for my project, the leds are still too bright even after setting them to a minimal value by software; after experimenting with various mechanical ways to dim them, i finally found out that cutting out simple adhesive white labels to cover the whole led strip and eventually adding multiple layers of labels does the trick. The leds do not heat so no fire hazard here.

Hope this is useful for some of you


Funny, I came up with the same solution after I had some sheets of laser printer labels left. Also at least a stop-gap solution for the Scroll HD pHAT. Still, I would prefer some frosted slab as a better diffusor, as in when mixing some colors the individual base color LEDs can still be seen inside a single pixel.
