if i made these, i’d scratch up the tip of the led to disperse light better.

i have here, sitting on my desk, ~20 leds with the tip sanded flat, they make for very good accent lighting.

I really like that, simple, unique, personal, non-commercial (well for now).

And to take the idea further, replace the battery with an appropriate resistor, some long thin wire and a USB plug.

The idea reminds me of this: http://metku.net/index.html?path=mods/multilayer-animation/index_eng

I just did a small-ish test with a piece of acrylic and a 5mm clear-blue LED. I ended up getting poor dispersion, about 10degrees in each direction, for a small piece (like in the tutorial linked) its perfect, but on a larger piece of acrylic (picture frame size) you’d need more LED’s.

Another improvement would be to sand the tip flat, or use 2.5×5mm rectangular LED’s. I might even try to make an animated gift-card since you could do one frame per layer.

I saw something similar to this years ago on metkumods. Looks like they/he have/has a new article up. I thought it was cool then and this version seems to be done without a cnc machine which I don’t have running yet.
