Method of self-made projector

The method of self-made projector is as follows:

Tools: shoe box, magnifying glass, watercolor pen, ruler, hand knife, adhesive tape.

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, use a magnifying glass or tape to find the center point of the side of the shoe box and draw a circle around it.

3. Then use scissors or a hand knife to cut along the marked circle.

4. Then 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. Then make a bracket that can be used to adjust the focal length with shoe covers, or make a mobile phone bracket with wire.

6. Making a simple projector at home is based on the principle of magnifying glass, so you need to set up a mobile phone screen. If it is an Apple phone, it can be adjusted in the auxiliary function settings. Android phone can open the screen selection of the phone. 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 start enjoying the movie trip.
