If you are like me and every time you crack open a coconut you find the shells just too cool to throw out then this instructable is for you. The idea of making a coconut shell thumb piano came to me one afternoon while I was trying to come up with some way to entertain my 3 and 5 year old girls. Of course after making them each one I needed to see if I could amp one up for myself. This was way too cool of a project not to try. As usual with all my instructables look to the image notes for the details.
Step 1: Lets Get Wired
In this step you will have on hand half of a coconut shell that you have already sanded flat across the opening and sanded off all the stringy bits on the outside. You will also have harvested a piezo element from a Dollar Store window alarm as well as a 1/4 inch stereo or mono jack. You will also need about 6 or 8 inches of speaker wire (or the power cable off an old AC adapter). Some wood for the top and some hot melt glue.
