    Show Idea: Self Powered Bluetooth Cassette Adapter for Streaming Audio


      I have been looking into adding a Bluetooth adapter to my existing car stereo.  I have done some research and found a few, but they all require you to charge them first.  I don't want to waste an outlet that I could be using to charge my tablet and my phone (for wifi hotspot)


      I was thinking it would be possible to use the spinning heads of the tape player in the car to generate a charge and store it in a battery while it is actually being used.



      - It should be able to support A2DP streaming audio if possible.

      - It should fit the form factor of an existing cassette tape, but could protrud out the access port if requried (i.e. for battery or other electronics).

      - It should be able to be self powered (trickle charge the battery from spinning heads of the player)


      Is something like this possible?
