Electric Coconut Thumb Piano

FeaturedContest Winner
Picture of Electric Coconut Thumb Piano
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.

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.

Step 3: Building the Bridge

Start with a couple of dowels cut to fit your sound board , you'll have to figure out how long they need to be based on the size of your coconut shell. You will also need a piece of 1/8 inch by 3/4 inch steel bar stock.  with a couple of holes drilled in the ends that will allow a screw to slide through. And of course you'll need some hot glue.

You are my competition, but i must say I love the sound you get out of these, its much more pleasing than my 8-bit noise maker. And they look nice to boot. good luck tomorrow, I cant wait to find out the judges decision.

I'd like to take this opportunity to thank every one who voted for me in the Audio contest, to just make it to the finals was and is a blessing. I don't care if I win, what I do care about is that you take the time with the young people in your lives to explore the world around you and above all else, make beautiful music.
