Bone Conductor Transducer on My Skull

by Aaron

 Thad made a project using the Bone Conductor Transducer from AdaFruit. He put it on my skull, and there was music in my head.

Thad sez-

I built an amp to go from a headphone jack to the bone conductor above, and got requests for a parts list.  The schematic is attached, it's from the 'typical applications' section of the LM386 datasheet, as 'amplifier with gain = 200'.  

Other parts I used:

- 9V battery

- battery clip

- male headphone jack

- 1.5 inch square pcb

The wires pulled off of the bone conductor easily.  After I re-soldered them, I glued them to the top.

I don't know about practical application, but it's fun.
