1x 10mm Dia. wooden dowel

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Disassemble That Earphone!

There are different types of earphones and in this guide I am using a stock earphone that came from a Samsung note 2.

1. Using a bench vice gently clamp the head of the earphone and gently twist the frame away from the head

2. Grab your Soldering Iron and carefully remove the wires from the terminals (make sure there is a marking for the + and - terminals if there is none, then better take a picture to know which one is which).

3. Cutting the wire would complicate things so better untie the knot and just remove the wire from the old earphone housing

Step 2: Sanding

Lock the 10mm wick inside the drill and Simply fit the wick inside the shell after that get a strip of sand paper and just remove the oxidized surface of the brass shell.

Step 3: Right Size?

As much as possible we would want to make the casing light as possible or else it might tend to loose whenever you put it in your ear, so getting the right size is must~

For my earphone I went with a 12.5mm

(Cutting tip with a hack saw for non drill users "bench vice only") ----Clamp it somewhere on the base area

Dont be afraid clamping the shell into the vice, just make sure its not too tight or else it will deform. Just the right tension to the point wherein it wont move when being cut. Your motion should always be in a single direction, to maximize efficiency of cutting, because if you are beginner in cutting tube metals you will find it hard cutting it the normal way (forward and backward stroke) It is possible to do this but I guess you need to be more experienced.

Step 4: Drill and Polish

I drilled the thing first then I polished it \

Clamp your shell just like in the picture, then drill in a 3mm bit.

Using your own metal polish just do the same process just like sanding step

(OPTIONAL) Clear Coat! if you want to retain its color then you'd want to apply some clear coat.

Step 5: Re Wiring

So basically we are almost done!

What you do now it to put it back all together

from the hole of the shell just wire it up, solder back, make a knot and close!

Step 6: Enjoy!

White or black what do you think? ... I think black is better

Great idea! If your child is found with them in school, don't be surprised if he or she is suspended.

The craftsmanship is awesome, but... doesn't it strike you as a little creepy to walk around looking like a bullet is entering your head?
