Picture of coconut headphones
For my entry into the laser-cutter competition, I decided to make a pair of coconut headphones. It took me about 2-3 hours to make, and it cost about $15 AUD.

Step 1: Tools and materials

Picture of Tools and materials
The parts list:
~2m of 4 core speaker cable, $3-$4 (this was complete overkill. get thinner cable)
2 speakers, $4-$5
stereo jack, $1.95
coconut, $2
headphone thingy, free from airline.

The tools list:
soldering iron
cordless drill
drill bits
hot glue gun
dremel (not shown)
heat gun

Step 2: Cut the coconut

I decided to make the Instructable after I cut the coconut so I can't give you any pictures. but, I will tell you how I did it.

drill hole through eye of coconut
drain coconut
put coconut in vice
with a cross-cut saw, cut not through the eyes, but the other way
get a butter knife and start prying the flesh out
eat flesh, drink juice, or make coconut milk

Step 3: Drill hole on the top of the coconut half

Get your headphone thingy and see what drill bit fits it best, then start drilling, and drilling, and drilling, then dremeling, and dremeling, and dremeling, and IT FITS!!! now make another hole for the wire.

Step 4: Now the other one...

Repeat step 3

Step 5: Making the headphone thingy comfortable

Put the headphone thingy in the two coconut halves, and try them on. if you have to push down on them to get a seal around your ear or it is just uncomfortable, do this.

As my headphone thingy was very, VERY uncomfortable (to the point of pain) with the coconuts on them, I had to make them wider. Yours may not be uncomfortable, so you are lucky and won't have to do this step. But for everyone else, here's how you do it:

Stretch your headphone thingy over something, ie a vice, under your desk etc. and start attacking it with the heat gun on max. When it is pliable enough, hold it in the position you want, and let it cool. You have to keep tension on it the whole time, other wise it will return to its former shape.
I like them. I was always a big fan of The Professor on Gilligan's Island.

To get the coconuts smooth, let them on a aquarium with fishes like ancistrus. They will eat all the fiber outside the shell.

but wouldn't that rot the wood?
I don't know why but the wood will not rot. I have coconuts on my aquarium for years now.

that's strange, but cool. I'll have to put the one a screwed up in my tank.
if you want to let the coconuts in your tank, you can had javamoss. It's not necessary to boil it to remove tannins. You can do a search in google with the keywords "aquarium coconuts" or ask me if you want more details.
leon finally you did something you said your going to

I would suggest adding some foam over the speakers to keep them hidden, and also some around the edge of the coconut, to make it more comfortable, Great Idea though, Castaway Tech Much?
