Hackaday Links: June 2, 2019

The works of Shakespeare, Goethe, and Cervantes combined do not equal the genius of Rick And Morty. Actually, the word ‘genius’ is thrown around a bit too much these days. Rick and Morty has surpassed genius. This cartoon is sublime. It is beyond any art that could be created. …read more

Ask Hackaday: What Is The Future Of Implanted Electronics?

Biohacking is the new frontier. In just a few years, millions of people will have implanted RFID chips under the skin between their thumb and index finger.

With a tiny electronic implant, Swedish rail passengers can pay their train ticket, and it goes without saying how convenient opening an RFID lock is without having to pull out your wallet.

That said, embedding RFID chips under the skin has been around for decades; my thirteen-year-old cat has had a chip since he was a kitten. Despite …read more
