Bluetooth Banana Phone Wireless Handset

Step 2 Hollow out the banana

Carefully use the X-Acto knife to cut out an access panel in the banana. You will be doing all of your work through this hole, so be sure to make it big enough to allow the Bluetooth headset and your tools to pass through it. However, keep it as small as you can to minimize the impact on the finished product.

Use the tweezers to hollow out a cavity to hold the headset. My banana appeared to be made of compressed styrofoam balls inside of a realistic looking plastic skin.

Surprisingly I found a chunk of cement (concrete) in the banana. I presume it's to give the banana the proper weight and balance. Unfortunately, the cement was exactly where I had planned on placing my headset, so I had to shift the focus of my efforts to the upper part of the banana.

I considered digging out from around the cement to remove it, but I had no way to tell how long the piece was, plus it may provide crucial structural support for the banana.

Also take a moment to make a paper or cardboard template of the circuit board. This will help you line up the USB port hole and sound holes for the earphone and microphone.
