I'm not ready to build another cube yet, but I'd like a place to keep track of all the small LEDs that I found. Do you know an inexpensive place to get 1mm x 1mm RGB SMD LEDs?
They are 0606, which at 1.6x1.6mm is still quite small. I really like the concave terminals--with the right jig, I think these would be excellent for thin vertical wire attachment.
Thanks for the tip Zak! Yes, I like the ones with concave terminals as well. Because we have to rotate them at each level, even better are the ones with CORNER terminals, like this:
Ah! Yes, corner terminals are ideal for you. I've used the PicoLED series in a few projects and it's a solid line... never tried the RGB version though. I say buy a few of each type you listed and see which is best in the real world!
I've putzed around with tiny RGB LEDs, specifically these ones: http://www.digikey.com/product-detail/en/LTST-C19HE1WT/160-2162-1-ND/4866310
