    Hi all, I would like to annoy someone when they are watching tv in my
    house, its basically a joke circuit that will change the tv channels and
    volume at random times to annoy them!

    I want it to be a circuit which is not connected to the tv, so it would have
    to control the tv by IR.

    Can anyone help me design this?
    I would really appreciate it!

    And maybe if it could be triggered by me, then that wold be good as well!


    Thanks
    Scott

    Search for a watch with a built-in TV remote control.
    You'd be fiddling with you watch.

    If you have a Palm PDA, get Novi Remote or similar and the scripting tools that
    come with pEdit. Then you can script a series of actions and just leave the
    Palm pointing toward the TV.

    Alternately, get a "remote extender" and put the receiver in another room. Then
    you can use a remote in the other room to change the status of the TV.

    How about one of those universal remote controls somehow connected to a 555
    timer?

    Thanks

  5. So simple it's pathetic. Go buy a $8 replacement remote control.
    Then solder a reed relay (so it can't be heard) across the button to
    change channels. Run the wire from the coil of the relay to a 9V
    battery and pushbutton switch somewhere convenient. Program the
    remote for your make of TV and hide it somewhere that's within range
    of the TV. Kick back and wait to have some fun.

    If you want to have some real fun, build a circuit with some 555s that
    delays the change so that you an conveniently leave the room and go to
    the fridge before it changes. Or if you really wanna get tricky, make
    a circuit that is voice actuated so that a high-pitched or ultrasonic
    sound triggers the relay. Or a light, or whatever or a combination of
    these.

    Another idea is to build a 555 that drives an IR LED that's pointed at
    the TV, so that it blocks out the regular reemote control. You set
    the channel where you want it, and no one can change it. I think that
    project is on www.wenzel.com.

  6. I don't like this watch remote. The IR LED uses a whole lot of
    current, and the watch has a single button cell, which will get run
    down rapidly. Besides, you have to aim the watch's LED at the TV and
    that gives you away.

    You can mod an IR remote control to be remotely controlled in
    various ways like at the below link.
