I was bored of turning the light on myself, so I built this! It's made from the LEGO NXT Mindstorms. It works by attaching a two long pieces to a motor. You also must have it stable so I lifted it up and taped it down. Finally attach a cord from the motor to the Mindstorms main unit. By the way, I programed it to turn on and off when I push the button, and I also programed it listen for my voice and turn on and off. Sorry some of the pictures are side-ways or bad quality.

Wow. It would be cool if you get a sound sensor and just say lights off! and it would turn off.

I can't really since I didn't take pictures of it when I was building it.

It doesn't take that long to take it apart. There isn't even that much pieces. It would also be very helpful to other people.

I made one of these at home a long time ago way before you made this instructable.

I made one of these directly connected to the Light Switch (actually, a fan switch.). I then set up a home-brew PIR sensor to detect if anyone was in the room, turning on the fan when it returned positive.

It works a lot better if you take longer outlet cover screws and add them through one of the holes in a beam, then build the entire structure off of that.

Let me get this you made a device that can turn on and off a light by you pressing a button. Its just that it seems really redundant when your pressing a button to flip a switch. Cut out the middle man and just use your own hand.

Same here. Maybe there is a good reason for building it. How could you be bored with turning a light on and off. Flip a switch or push a button, they're just as boring! Besides, you probably spend less than 10 seconds a day turning lights on and off. ANyways, if you want to make this more worthwhile, install a dimmer, and have that controlled with your LEGO thing.
