1-10 LED's, Any color, any size (I used 2x 5mm red LED's)
Drill & LED-sized (5mm usually) drill bit
Little rasp to file LED's holes to fit with your LED's
Speakers , I used Creative TravelSound -speakers
Screw driver (if required for removing the speaker boxs cover)
4 Wires (1-30cm, that's about your speaker's size and where do you want to place the led's)
So, let's get started! :)
Video about all this :
Step 1: Select the Place for LED's
You need to select the place for LED's, and mark it with a pencil. Check that you have space inside the speaker box for leds!
Step 2: Drill Holes to the Marked Places
Drill holes to the marked places where the LED's comes. Use rasp to make hole to fit with the LED.
Step 3: Solder
You need to solder your wires to the speakers + and - sides, the sides with the LED's does not matter.
Then solder your LED's + or - side to the wire, and solder the other wire to the other LED side too. Do this step again with the another speaker.
Step 4: Place the LED's
Put your LED's to the holes you drill'd. Check that your wires does not touch each other, or your speakers does not work!
Step 5: Finishing
Put case back together, and enjoy!
