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...

• Can You Design And Build A Smartphone Projector? Creator Sheet
• Two Boxes (one smaller than the other)
• A Magnifying Glass Lens
• Black Duct Tape
• Pencil
• Craft Knife Or Cutting Tool
• Smartphone

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,
