Sony TV Remote Control Mod - Ultrabright LED Torchlight

videoThe ultrabright green LED torchlight in action. Notice the pulsating green light. A TV remote control actually sends out pulsating infra red light to the TV. The TV interprets the sequence of pulses as control signals and react accordingly.

In this case the remote control sends out pulsating green light because the infra red LED is replaced by a ultrabright green LED. Notice the wide beam angle from just a single ultrabright green LED.
