Can You Design And Build A Smartphone Projector?

Looking for a fun way to keep teens learning this summer? Our new STEM challenge will have kids build a smartphone projector they can use over the summer.

What you need per person/group...

What you need to do...

  • Students will begin by picking groups and/or working independently. Pass out a Creator Sheet to each student or group.
  • Find a dark room and turn on your smartphone, place the smartphone a set distance away from the lens pointing at a white wall.This will give you the opportunity to see how big you want your picture to be. 
  • Next we will install the lens (mount it) onto the box, cut your hole and repeat with the second box, using the duct tape to secure the lens. 
  • Turn the smartphone on light, and then you will make slices within the box to fit your smartphone inside.
  • You will now want to cover the box in the black duct tape, so that the light does not bounce off on the inside, and wash out your picture. 
  • You will then need to set up your smartphone for the projector, you will need to invert your screens.
  • Now time to test out the screen! 

We would love to see you try this STEM Challenge. Share your results with us through social media!

Happy Making,

Maker Maven
