Wireless audio transmitter is used for watching your favorite TV programs without disturbing others. You can buy ready-made audio transmitter but they use batteries both in receiver as well as in the transmitter and they easily drain out. So in this video we use 4$ Mp3 car modulator and old USB cable from old mouse to make your own USB powered RF TV audio transmitter.

Note : You can connect as many receivers as you wish, just point to the RF frequency you set in the transmitter and enjoy your show using your mobile FM or any other FM device.
