Cut the top of the cardboard box and put a piece of cardboard about halfway in the box along with the Fresnel lens in it and firmly secure it with tape (See pic 1). Cut out another piece of card board which is the same size and width as the main box and cut a hole in it for your light to be fixed in.
Cover the cardboard around the hole with tin foil. This will reflect the most light, which is needed. Then insert the said piece into the main box, making sure that it is in line with the Fresnel lens and it is at least 3 inches away from it.
You can also put a cone and a condenser lens or a strong magnifying glass on the light to make it a lot brighter.

You won’t get the level of satisfaction
and self-content that you can get from doing things on your own. One can
buy stuff at stores or on internet, but if you can build something on
your own, no matter how big or how small; it will always be a pride
moment of accomplishment.
Here is a way to build a projector out of some cereal box and things that you can find in your house.1 Things required building this projector
One requires a large cardboard box, a
Fresnel lens and a regular magnifier glass. You also need a bright light
such as a LED or LCD, whichever you find cheaper. A round cylinder of
some kind as same size as the magnifier glass (pringles box will do).
Other things required are aluminium foil, tape and scissors. The LCD light can be found on eBay for $20 or so.
