Can you (or somebody) please make a site where people can order stack so of them with the leds in custom positions (printed biz cards with the nfc-harvested led coolness)?
Ideally, LED color, quantity, size/brightness, and location could be customized (within reason).
I could see people buying stacks of 5, 10, 50, or 100 of them at once.
Really great project, thanks for sharing and what a well done write-up! Also kudos for including the PCB, BOM, and code on GH with a permissive license.
