NFC Energy-Harvesting PCB Business Card with an ancient culture had zero?

Okay, I really like this, but apparently modern Gigabit ethernet adapters are able to detect this situation automatically?

It has been pointed out before that although we know of no cultures which used a bijective base number system (well, besides base 1!) it might not be more "beautiful" than anything else. Every individual product is "easy", but the moment you want two ecosystems to talk to each other. Still, a seriously neat piece of engineering! For future PCB business card ideas: it would be very sped-up, but maybe it would increase "immersion" nevertheless. Last time I've looked at Relm4 it was in a paper which was about how many times the bijective base system had been independently reinvented by mathematicians. Re: the slight wobble, you should be able to order cheap ones in packs of 5 or 10, with custom led colors/locations/sizes/brightness, fitting into a printed card...
