Headphone holder

A support for your headset is a bit special, it has an internal light in addition to having a USB connection based on the support.

The light in the support is programmable, eventually you could choose the color of the light as well as the animation of the LEDs.

It is possible to reprogram the Arduino Nano to make other lighting effects, but for now, we will focus only on one configuration.

Simple support assembly

We’re going to start with something easy. The assembly of the support without electronics.

The assembly is very simple.

  • Insert the head of the guitar into the rectangle at the base, make sure you are on the right side.
  • Screw both M3 7mm screws and voila, it’s over.

Assembly of LED and USB support

Insert the head of the guitar into the rectangle at the base, make sure you are on the right side.

You’re going to need a male/female USB cable.

You will cut the female part to 250mm from the end of the connector.

You have to strip the wires by being careful not to cut the wires inside the sheath and keep only the black thread and red thread (usually they are bigger than the others) and the other wires, you will cut them.

Pass the four wires into the hole below the base so that they are inside the guitar.

To prevent the wires from coming out, a little hot glue must be put at the entrance of the wires.

You also have to glue the female USB connector to keep it in place.

Now cut an LED strip that will contain fifteen LEDs, be careful to cut the LED strip in the right place because you are going to have to weld at both ends of the LED strip. Weld the three wires (red, black and any color of wire), the length of the wires will be 20 cm, before welding them, notice well the direction of the small arrows on the LED strip, your wires must be welded in the same place as in the photo. On the side of the small arrow it will be the black wire, in the center it is the wire for the data and at the other end it is the 5V.

And at the other end, it’s the same thing, except that the wires have 3 cm.

Bend the LED strip a little on the edges so that you can fit it inside the handle of the guitar.

Connect the two red wires together and another 10 cm red thread, then weld them together and put a shrinking sheath to secure it all.

It’s almost the same for black wires, except that in addition to a 10 cm black wire, you’ll also take the black thread from the LED strip, still the same case, weld them together and then install a shrinking sheath.

Insert the LED tape inside the guitar handle. By passing all the wires below the LED strip, make sure the arrows in the LED strip are moving in the right direction.

For the following, I will try to be as specific as possible, but if there is confusion, refer to the diagram above.

Install the switch.

Weld the 10 cm red thread on either side of the switch.

Weld a resistance of 330 Ohms on Arduino nano D4.

Cut two 6 cm wires, one red and one black, then weld the red thread on the 5 volts of the Arduino Nano and then the black thread on the GND.

Put glue on the capacitor.

It’s a capacitor of the 1000-f 35 volts.

Then stick it next to the switch.

Put some glue on the Arduino Nano.

And place it in its location on the side.

Twist together the 10 cm black wire and the 6 cm wire and weld them together.

Same goes for red wires.

Weld the two red wires on the positive side of the capacitor.

Now weld the black wires to the negative side of the capacitor.

Cut another 4 cm red thread and weld it to the positive side of the capacitor and the other end of the wire will be welded to the other pinne of the switch. Refer to the photo.

the large thread that remains will be welded on the resistance welded earlier on the Arduino Nano, in my case the thread is blue.

Last thing to weld is the other LED band comprising 42 LEDs. Make sure the small arrows are common sense, then weld the other three wires to their respective locations.

I strongly suggest you stick the LED strip to make sure it won’t take off.

Here’s what it looks like when it’s glued.

Download the file to program the Arduino Nano.

  1. Board: “Arduino Nano”
  2. Processor: “ATmega328P (Old Bootloader)”
  3. Port: “COM (communication port number). Example: COM5
  1. Click “Manage Bookstores”
  1. Enter “Adafruit_NeoPixel” in the search bar
  2. Choose the latest version and then click “Install”
  1. Click on the arrow to start the program tele-payment at The Arduino Nano.

You have to close Cura because you might have a communication error when you are going to program the Arduino Nano.

You can color the small strips if you wish.

Before you put the glue make sure everything is functional, then stick all around the case and paste the top. As usual, I always use a glue made of acetone and ABS filaments.

Press firmly on the lid.

Then install greenhouses or something to hold the lid in place.

Install both 7mm M3 screws and it’s over.
