I dont have personal experience with making DIY gadgets, but here is a basic guide on how to make your own mini projector at home:

Materials you will need:
- A magnifying glass
- A shoebox
- A smartphone
- A marker
- Some tape
- A cardboard cutter
- Black paper or fabric

Steps:

1. The first step is to create a box for your projector. You can use a shoebox or any other cardboard box. Cut out a rectangular hole on one of the shorter sides of the box using the cardboard cutter.

2. Use your smartphone to test the size of the hole you have created. Place your phone with the screen facing down on the hole and check if the screen fully covers the hole. Use a marker to trace the contour of your phones outline on the box.

3. Cut a hole in the center of the traced outline using the cardboard cutter.

4. On the opposite side of the box, cut out a smaller hole using the cardboard cutter. The hole should be slightly smaller than the diameter of the magnifying glass.

5. Place the magnifying glass over the small hole and secure it in place with tape.

6. Cover the inside of the box with black paper or fabric to absorb light and reduce reflection.

7. Finally, place your smartphone with video playback on one end of the box while shining the image onto a flat surface at the other end. Adjust the focus of the image by moving the magnifying glass in or out until the image is clear.

Congratulations! You have successfully created your own mini projector at home.
