how to make mini projector
A mini projector allows a video to be projected onto a much larger screen. While a mini projector can be smaller than a smartphone, it can display images on much bigger screens. In order to make your own mini projector, you'll need an LED light, water bottle cap, thumbtacks or tape and some kind of transparent object. Glasses work as well as anything else that is transparent. You'll also want to have any kind of clear or translucent lens that will fit over the opening of the water bottle cap and stay put with either tape or thumbtacks. Preparing the LED light. Make sure the LED light is on its side (it will be upside down in your final product). The LED has at least three pins, two of which are long and one of which is short. Strip the wires off of all three of those pins. You can now twist those wires together to form a thick wire if you'd like, but I preferred to leave them as they were because they didn't need to be wound very tightly or keep a tight bend.
