The device that makes a cathode-ray tube (CRT) type television an oscilloscope was developed. The conventional analog broadcasting will be stopped to shift to the digital broadcasting completely on July 24, 2011. Therefore, a large number of cathode-ray tube type televisions will become unnecessary, and they would be discarded in large quantities. They would become the great pressure to the environment. To reduce such social anxiety, and to use such televisions as oscilloscopes effectively for the learning of the electric and electronic technology in a technology education course in a junior high school, the device that makes a television anoscilloscope was developed.The result of production of this device, the expected purpose of observing an electric signal on the television could be achieved under the limited condition. Further several improvements will be added to the device in the future.
