That moment you take your eyes off the TV remote for just a second, because of which it falls into the hands of your annoying sibling. Yes, fighting for control over the TV is a daily struggle for many. But the TV Remote Jammer shown in this Instructable, will make everyone else stop dead in their tracks.
This Remote Jammer circuit, in the disguise of an inconspicuous TicTac Box, sends a constant signal to the TV receiver that interferes with the signal from the TV remote. This means that when the Jammer is on, your TV remote CANNOT be used to change channels. It practically blocks all signals from the remote.
This cheap circuit will make you the King of your TV; now you can watch your favourite shows without anyone disturbing you! And better still, no one will even know what’s wrong. A small TicTac box would be the last thing that anyone would think of being the cause of their problem.
Let’s dig into the details:
- What is a TV remote jammer? – A handy little circuit that blocks the signal from a TV remote, so no one can change the channel.
- Why a TicTac Box enclosure? – No one would be suspicious of your evil electronics skills.Pretty simple. Have a look at this picture above. The usual TV remote sends a pulsed IR signal which has some instruction encoded in it, like increase or lower the volume, or changing the channel. This remote jammer, however, sends a steady IR pulse at about 40kHz. This pulse has no data encoded in it. Hence the TV receiver receives no instruction, even if some one else is frantically pressing buttons on the remote.
