Step 1: Things That You Need
-magnifying glass (cut handle)
-shoebox (any kind that fits in your phone or tablet)
Step 2: Glue the Side of the Box
glue the corners of the box to prevent it from wiggling. I'm using hot glue because i ran out of PVA glue.
Step 3: Tracing and Cutting a Round Hole
use a ball pen or a pencil to trace the magnifying glass, now grab your compass and cutter to cut off a perfectly round hole. if you don't have a cutter you can use a hobby knife.
Step 4: Remove
remove the cut piece from the box but save it for later.
Step 5: Positioning the Lens
position your lens right in the center.
Step 6: Glue the Lens
Step 7: Cut Off the Protrusion
use the your previous cut out as a stencil.
Step 8: Make the Phone Stand
make sure that the stand fits in the size of your phone.
Step 9: Tape Your Phone
use a double sided tape to mount the phone in the stand
Step 10: Set Your Phone
-you must set your phone to the highest brightness.
-then lock your screen
Step 11: Adjust Your Projector
to adjust the projector you must move your phone backwards until you get the sharpest projection and if it does not work extend the back of the projector.
Step 12: Watch in the Dark and Enjoy.
