This kit contains all of the electronic parts required to build "Charlie Bear", an RFID teddy bear project featured in MAKE volume 28 (page 108). All you need to supply is a teddy bear, or other plush toy, the sewing bits and SD Memory Card. Everything else is included, even the batteries. See below for all the details.
Please note: We tried to add a Teddy Bear to the kit, but our warehouse workers just couldn't tape the boxes closed with those poor little teddy bears looking back at them. Needless to say, You're on your own for sourcing a furry little friend for this project.
This location-aware teddy bear reads RFID tags and plays
different customizable sounds depending on where it is or what
object it’s near — other toys, books, CDs, anything.
Charlie’s Bear helps children explore the
world around them by producing sounds in
reaction to other toys or objects nearby. It
can play any sound files you upload to the
memory card inside — for example, the voice
of the bear, a noise that another toy might
make, a theme song prompted by a toy from
a TV show, or a reading of a favorite book.
David Harris created the toy for his nephew Charlie,
who was born with cerebral palsy. Charlie’s
vision is poor, but he’s very tactile and auditory.
This toy takes advantage of his excellent
hearing and the joy he derives from music
and sounds. And for all young children, this
toy is an easy and safe way for them to pick
their own music. Just bring a CD case (or
other tagged item) near, and the bear plays
it — no complicated CD player or computer.
At the heart of Charlie’s Bear, an Arduino
microcontroller uses a radio frequency identification
(RFID) reader to recognize nearby
RFID tags, then uses an audio shield attachment
to play corresponding audio files stored
on an SD memory card (not included).
