Manufacturing method of self-made projector

The manufacturing method of the self-made projector is as follows:

1 First of all, we need to prepare tools and materials, mainly including shoe boxes, magnifying glasses, watercolor pens, rulers, hand knives and rubber strips. Note that friends who don't have hand knives can also prepare scissors.

2. After the tools are ready, we need to find the center of the magnifying glass or rubber strip on the side of the shoe box and draw a circle around it.

3. Step 3, cut down along the marked circle with scissors or a hand knife.

4. Step 4: Fix the prepared magnifying glass in the shoe box that just came out with adhesive tape to ensure that there is no light source around to project, so as to form a good projection effect.

5. Step 5, make a bracket that can be used to adjust the focal length with the shoe cover; Or use wire as a mobile phone bracket.

6. To make a simple projector at home, we use the inverted image principle of a magnifying glass, so we need to set up a mobile phone screen. If it is an Apple phone, we can adjust it in the auxiliary function set; Android phone, we can open the phone screen. After adjustment, put it in the finished mobile phone bracket and find out the focus.

7. After the production is completed, cover it. Find a white wall, turn off the indoor lights, and you can begin to enjoy our movie trip.
