45: Communicate wirelessly using a book
npub17yfvmsc0j6m8694pxy8lrdnh6lf5f35lfke9ywdny7l5x5vt3kzqm4cf98 (npub17yf…cf98) and I played around with NFC a bit more, and we found out that when getting close to a tag, a smartphone emits at 13.56 MHz continuously!
So, we sent Morse code to each other between rooms, using a smartphone and a library book! :'D
Take that, Bundesnetzagentur!
Seems that the shortest signal you can create is 70 ms long, resulting in a meager communication speed of ~10 words per minute…
