FM Wireless Headphones for TV or PC

This is a istructable to create a Wireless headphones using a CAR FM TRANSMITTER.

The good thing is that there is no limit of people to connect to the transmitter.

MATERIALS:

• Car FM transmitter
• Device with radio FM ( I use a mobile phone )
• Scissors
• Electric transformer to 12V
• Electric wire/

  cable

  ( 25cm )
  
• Double Jack male cable
• Insulating tape

I use this transmitter but you can use other , all work equally: http://www.ebay.es/itm/Car-Player-FM-Transmitter-R...

1. Let's cut the electrical wire/cable into two halves, one bigger than the other.

2. We removed the plastic from the three ends (1cm), the other end in 3cm (picture 2 )

You will need a electronic transformer of 220-230 Voltage to 12V, is not necessary a concret transformer. ( AD/DC POWER SUPPLY )

Remember this: The outside of the transformer output is negative (-) and the center is positive (+), you can see this in picture 1.

1. The long wire/cable will be the negative, the short wire/cable will be the positive. Conect same the picture 2, 3.
2. Put the Insulating tape same as picture 4.

Look the firs image/picture: side connectors are negative and the tip is positive.

1. Conect the wire/cable same as picture 2 and tray it. IF it's works follow the second point. IF it doesn't works tray to change the cables. (picture 2 )
2. Put the Insulating tape same as picture 3 without desconecting.

Conect the Jack cable with a transmitter and the other connector with a TV or PC.

• With a remote controll device inclued in the pack, change the frequency. Us a frequency that is not used by any radio.

• With a mobile phone or other radio device search the same frequency and listen wiht headphones. Controll the device volume and TV or PC volume to increase the quality.

• Uses a frequency that is not used by any radio.

• Us a good headphones to increase the comfortability.

• If you want you can solder the wire to not use the insulating tape.
