This would be a fun project to do with your kids,  Especially this time of year when you might be wanting to show off pictures at Thanksgiving Dinner or at Christmas Parties.

Thing You'll Need



Materials:

- Magnifying Lens

- Foam board

- Smartphone

- Gluesticks

- PVA Glue

- Shoebox

Tools:

- Hobby Knife (XACTO)

- Hot Gluegun

- Cutter Knife

- Hacksaw

- Ruler




Carefully use your hacksaw to cut off the handle of the magnifying glass




Reinforce the box by gluing the flaps and corners of the box. This prevents it from wiggling.   Don't get too excited. Let it dry for a few minutes.




Lens Placement: Position your box in an upright position. Place your magnifying lens on top then center it. Use a pencil to trace the cut line.




Position Your Lens before gluing the it in place.




Build the Phone Stand using a foam board. Make sure it's perpendicular from the base to avoid image distortion.




 Tape Your Phone: Use a double sided padding tape to mount your phone on the stand.




Like all projectors, this one needs to be calibrated too. Position your phone at the very end of the box then slowly move it closer to the lens, you will notice that the image will turn sharper/ softer. Move it back and forth until you get the sharpest projection.
