What is a DIY box projector and how does it work?
A DIY box projector is a homemade device that uses a smartphone or tablet to project images or videos onto a screen or wall. It works by using a magnifying lens or a Fresnel lens to focus the light from the device’s screen onto a larger surface, creating a larger image. This is a fun and creative way to repurpose an old cardboard box and create a unique entertainment system.
The DIY box projector uses the principle of optics to magnify the image from the device’s screen. By placing the device inside the box and shining the light through the lens, the image is enlarged and projected onto the screen or wall. This is a simple yet effective way to create a projector without spending a lot of money on a commercial device.
What materials do I need to make a DIY box projector?
To make a DIY box projector, you will need a few simple materials, including a cardboard box, a magnifying lens or Fresnel lens, a smartphone or tablet, a screen or white wall, scissors, glue, and tape. You may also want to add some decorative materials, such as paint or markers, to customize your projector.
You can find most of these materials around the house or at a local craft store. The cardboard box can be any size, but a larger box will generally produce a larger image.
