Roll Your Own RFID Tags

Roll Your Own RFID Tags

Beth’s prototype design, here, uses 100 turns of AWG 40 magnet wire, an ATtiny85 integrated circuit, a couple of surface-mount capacitors, and a duct-tape substrate sealed under a layer of clear packing tape. She reports that “the read range is practically indistinguishable from a mass-produced RFID card.” [via adafruit]

    Proyek keren lainnya yang mengimplementasikan ATTiny85. Proyek ini mengenai RFID yang dibuat sendiri, tentu saja coil juga harus digulung sendiri. Tanpa memakai tenaga baterai apapun. ATTiny85 tipe SOIC (tipe Surface Mount Device) ditenagai oleh arus yang dibangkitkan oleh coil yang terpapar sinyal elektromagnetik dari komunikasi yang dilakukan. Cool!
