heto nakita ko lang sa wikiHow...
Steps:
1 Obtain any cheap webcam.
2 Remove the outer shell to reveal the circuit board the lens is mounted on. This makes the camera considerably smaller.
3 Get an old desktop pencil sharpener, and remove the motor, wires, and power cord from the inside. Make sure it is unplugged!
4 From the inside, mount the camera inside the sharpener using superglue. Glue the outer rim of the camera lens to the hole in the sharpener that pencils were inserted to be sharpened.
5 Tape or glue or fishing weights to keep the hidden camera from being unnaturally light.
6 Thread the USB cord (the cable that is used to connect the camera to the computer) through the hole that the power cord used to go through.
7 Affix an "Out of Order" or "Broken" sign to the sharpener so people do not try to sharpen their pencils in it and break the camera.
8 Point your camera toward the door.
Tips:
If your camera has an LED light that lights up when it is on, be sure to disable it.
If your camera has a microphone, cut a tiny hole in the sharpener under the "Out of Order" sign and glue it there
If you have a Macintosh, download a program called Macam from
http://webcam-osx.sourceforge.net/ . This is a great program as it will let you record and take pictures. Many webcams are not compatible with Macintosh computers.
Warning:
When you reveal the evidence, just tell your parents and sibling that you left an ordinary video camcorder running in the room. Do not reveal your secret weapon!!
