The premise is to permanently embed a Bluetooth headset inside of a fake banana, while exposing the necessary sound holes and USB port for in-place charging.
In practice, it took some time and patience to place the headset such that it remained functional inside of the banana.
One thing I would do differently would be to extend the length of the microphone wires so that I could increase the distance between the earphone and the microphone, and to insert some sonic insulation between the earphone and the microphone, as my finished banana phone gives a terrific echo back down the line to the remote party.
I apologize for the low quality of my photos. I recently "bricked" my digital camera by leaving it outside in my vehicle during some of Nebraska's coldest days. The photos in the instructable were taken using the camera in my LG Chocolate phone.
This project was inspired by the DIY Banana Phone at Make Magazine, as well as the Bananaphone song by Raffi and remake by Rhonda Vincent.
