Building A Projector

To learn how to make a DIY smartphone projector, first, you are going to get a piece of plywood. Decide how big you want your projector to be, then measure it, mark it and cut. Remember, your magnifying glass will act as a lens so plan the size of your box accordingly.

Next, cut the handle of the magnifying glass and trace around what is left, on the wood, where you want your lens to be located. Cut out the hole in the middle and use your jigsaw to cut out the spot where the magnifier will go. Make sure that it fits in the hole nice and tight. It should fit flush so that no light is escaping from your homemade projector.

After that, glue and nail your pieces together, creating your projector box. Make a lid if you haven’t done so already. The next step is to paint the inside of the box so that it is as dark as it can be inside. Glossy black paint will be perfect. You can also line it with black paper. Your phone is the light source after all. You can use some foam boards to hole your smartphone in place.

That’s it. You are done. Set your phone inside the box and start movie night! You can use a projector screen or just a blank wall. You can have an outdoor movie night or indoor home entertainment. You now have a projector for your smartphone.

Helpful Tips

  • Measure twice, cut once. This is an important rule.
  • Determine beforehand how big you will need your box to be, by building a rough mockup and testing it with your phone. You can use a smartphone or tablet.
  • When playing movies you have to lock your phone screen rotation on your smartphone.
  • The movies also have to play upside down since the ‘lens” will flip the image right side up again. This is similar to how our eyes work.
  • You can also use a cardboard box and hot glue from a glue gun if you want it even easier.
  • Assuming that you have most of the tools here, this build will cost you about $15.
