TV REMOTE CONTROL JAMMER Circuit
This circuit confuses the infra-red
receiver in a TV. It produces a constant signal that interferes with
the signal from a remote control and prevents the TV detecting a
channel-change or any other command. This allows you to watch your own
program without anyone changing the channel !! The
circuit is adjusted to produce a 38kHz signal. The IR diode is
called an Infra-red transmitting Diode or IR emitter diode to
distinguish it from a receiving diode, called an IR receiver or IR
receiving diode. (A
Photo diode is a receiving diode). There
are so many IR emitters that we cannot put a generic number on the
circuit to represent the type of diode. Some types include: CY85G,
LD271, CQY37N (45), INF3850, INF3880, INF3940 (30). The current
through the IR LED is limited to 100mA by the inclusion of the two
1N4148 diodes, as these form a constant-current arrangement when
combined with the transistor and 5R6 resistor.
