More Good News About The 'Scientific Accident That May Change The World' Graphene supercapacitors | Photo: UCLA That battery life video that had gone viral due to a recent post on UpWorthy (and which we told you about Tuesday) now has an update. We told you that researchers at Ric Kaner's lab at UCLA had found a way to make a non-toxic, highly efficient energy storage medium out of pure carbon using absurdly simple technology. Today, we can report that the same team may well have found a way to make that process scale up to mass-production levels.
Micro NFC/RFID Transponder - NTAG203 13.56MHz ID: 2800 - $2.95 This tiny micro NFC/RFID tag is super small, and contains an NTAG203 chip plus antenna. It's super tiny, flexible and a great way to DIY an RFID or NFC device if you're interested in designing your own ring, wearable or whatever other tiny device with near field communication incorporated.
