Abstract
Using teaching aids is an important factor in performing teaching and learning activities as we
cannot take the students in to real situations or real places. However, pictures or even authentic materials
cannot sometimes be clear seen by all the students throughout the classroom. One way to solve this
problem is using Visualizer to present the pictures or real things. But such hardware is too expensive to use
widely in school. Consequently, the idea to invent a similar Visualizer with high quality but cost less has
occurred. This new invention was named Video Presentation Stand: Easy K-02. It can mainly substitute
the Visualizer and can operate the following tasks 1) It shows the pictures of letters, handwriting,
paintings, authentic materials and things from the microscope in order to present the real thing on TV
screen or LCD projector 2) can take the pictures with short and long distance (<1 cm ___-∞___ ) 3) It has
a microphone which can be used with the amplifier 4) It has light weight and save electricity (1 Kg./8 V
200 mA 5) It has reasonable price (800 baht).
