For this DIY Smartphone Projector (that will REALLY WORK!) you will need: 2 shoe boxes (2! not 1!), magnifying glass (I used cheap magnifying glass which diameter was 75 mm), electrical or black duct tape, scissors and knife, black paint, a pencil and a ruler, smartphone (or even PAPER PHOTOS!).
You’ll need a smartphone holder, so I made one out of a plastic bottle bottom (watch in my video tutorial).Set the holder to the inside back part of the first box (that one which is without magnifying glass). Put your phone to the holder (screen should be turned to the magnifying glass).
Important! Phone settings! Turn phone screen brightness to the maximum. Turn off screen rotation. Flip your phone upside down (so ppl in video or photo will be turned – their feet will be up, and their heads will be down).
About focus and distance: tune the focus with moving your smartphone (with holder) backwards and forwards in the first box. Here are few tips about distance:
1. Distance from phone to magnifying glass – 60 cm, Distance from magnifying glass to the wall – 1 m, image size – ~8 inch
2. Distance from phone to magnifying glass – 50 cm, Distance from magnifying glass to the wall – 1.5 m, image size – ~15 inch
3. Distance from phone to magnifying glass – 40 cm, Distance from magnifying glass to the wall – 5 m, image size – ~60 inch
So, turn off light in your room and start the movie! 🙂
