Building an outdoor plant box with a built-in time projection chamber is a unique and functional project that combines gardening with technology. Here’s a step-by-step guide to help you create your own:

1. Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws, nails, and wood glue

- Waterproof sealant

- Small LED projector or digital clock with projection feature

- Basic tools (saw, drill, measuring tape)

2. Construct the Plant Box:

- Cut the wooden planks to your desired size (e.g., 24"x12"x12").

- Assemble the box using screws and wood glue, ensuring it’s sturdy.

- Apply waterproof sealant to protect the wood from moisture.

3. Create the Time Projection Chamber:

- Cut a small compartment on one side of the box to fit the projector or digital clock.

- Install the transparent acrylic sheet as a window to project the time onto a surface.

- Secure the projector inside the compartment, ensuring it’s protected from the elements.

4. Finishing Touches:

- Fill the box with soil and plant your favorite herbs or flowers.

- Test the time projection to ensure it’s visible and adjust the angle if needed.

This DIY project not only enhances your garden but also adds a modern touch with its time projection feature. Happy building!
