I do not have practical experience in building a short-throw projector. However, I can suggest a general outline of the process carried out to build a short-throw projector:

1. Choose the optics: The key to a short-throw projector is the lens, which magnifies the image projected and allows it to display on a larger screen from a shorter distance. Choose an appropriate short-throw lens for the projector.

2. Choose the projector module: Youll need a projector module for displaying the image. You can either buy a ready-made projector module or build one from scratch using DLP or LCD projectors.

3. Choose the screen: A short-throw projector requires a special screen designed to handle the extra light that is thrown at it. You can purchase a specially designed short-throw projector screen or use a white wall to display the image.

4. Assemble the platform: Short-throw projectors require a platform to hold the lens and projector module. The platform can be mounted on the wall, ceiling or on a table in front of the screen.

5. Create a power source: Youll need to create a source of power for your projector, whether through batteries or AC power.

6. Connect the components: Connect the lens, projector module, and power source together and ensure it is working smoothly.

7. Fine-tune the projector: Fine-tune the picture using the projector controls until you achieve a clear, sharp image.

Keep in mind that building a short-throw projector requires some technical expertise and can be a complex process. It is recommended that you seek professional help or do thorough research before attempting to build one.
