First and foremost, for the topic of my thesis I design a wireless, self-powered device, that is actually a dice with
the help of RFID technology.
This dice tells the outcomes of the dice rolls. It contains a three dimensional accelerometer that defines the
direction of the acceleration. This data is sent through to a microcontroller via SPI or I2C interface. The microcontroller's
main task is to convert the accelarion values to a dice roll, assaigning a number to the received values. After this,
The microcontroller sends this data to an RFID tag (transponder) that writes this data to the RFID tag's memory. The dice is placed in
the near field of an RFID reader. The reader's main purposes are to handle the dice roll datas from the tag memory
and to provide the dice with power. This power is established throught magnetic induction. The current loop in the reader antenna
induce magnetic field around its near field. This magnetic field excite and separate electrons in the tag's antenna that leads to
current flow. The absorbed energy is stored in capacitors that supply the dice with power including the tag,microcontroller and the accelerometer.
My task is to design this dice's electronics and its mechanical appearance and to realize this thesis if time allows.
