Based on the available context, a very low-tech, rudimentary "overhead projector" can be created using a stack of books to act as a platform. It's important to note this is not a true overhead projector but a simplified method for raising and displaying something.
Building a Makeshift Platform
The core idea is to create a raised, flat surface.
- Find a Flat Surface: You'll need a flat space to work on, such as a table or the floor.
- Stack Books: Gather a stack of books. The height of the stack will influence the viewing angle and size of what you are displaying.
Limitations: This method simply elevates something. It doesn't provide the illumination or lenses required for a true overhead projector. It's more akin to a document stand.
