Pseudo Talisman (with BT)

This is the Pseudo Talisman that simulates all the bluetooth radio activity that would be transmitted and received by a final Talisman.

This device will enable the development of the Android Bridge prior to the completion of a Talisman. The device allows imitation of the data that a Talisman would send over the Bluetooth 2.0 radio.  The device also allows capture of data sent from an Android Bridge to a Talisman.

Full control over the Bluetooth radio allows recreation of events involving power cycling of the radio, changing modes of the radio, detection of pairing status of the radio and data sending and receiving.

There are two identical devices, one for sending to Nadar and one for Allan.

The device does not have any screen or physical buttons, and makes use of a serial link provided via the black USB cable. The device appears as a serial port. A set of commands is sent to the device over a serial port. An example command would turn power on or off to the radio.

Any activity detected by the Pseudo Talisman Bluetooth Radio is echo-ed to the serial port for viewing in any laptop serial terminal application.

Any extensions or new features could be added via a firmware upgrade in the Pseudo Talisman. The Pseudo Talisman uses the cheek and cheerful Arduino Nano 3.0 device (board with the USB cable), a relay to switch power to the radio (board with the blue box), and a Bluetooth radio identical to the module used in the Talisman (third board with all the wires coming off the end.

Final Prototype (in parcel)

The final resin cast talisman prototype was included in the parcel. Each item in the parcel has a descriptive note in each zip lock bag.

The included resin prototype had all components mounted inside clear resin to allow sculpturing the talisman shape. The final unit will be milky opaque and not clear.

The included prototype did not have a PCB included so one of the two nuts was loose and has been weakly glued in place. The final talisman will have the nut on the top side of the PCB and will not fall out because the PCB will hold it firmly in place.

The final device will be either bolted onto a custom personalised wrist strap, or will be worn around the neck as a pendant with a chain attacked to the rear of the talisman.

Power is applied to the device with a magnetic clasp once a week to recharge the device.
