Here's a simple way to make an LCD viewfinder for your DSLR camera (or any other LCD display)!!
It'll cost about $5 but most of this stuff you probably have around your house, so it'll really cost you nothing!!
Baby Powder Container
(or any container with a round hole at one end, and rectangular end on the other side).
Magnifying glass (plastic lens)
Rubber bands (hair ties work great, and add a pro look).
A set of earphones, you'll need the padding from those (just one).
Some hot glue and paint.
Let's get started!
With the lens in place, put the container on the LCD of your camera and test the focal length. If it's out of focus, trim a little off the bottom of the container and check again. Continue to do this gradually trimming the bottom of the container so you can get the custom focus for your eye with your viewfinder (container).
Be sure to prep the plastic and use paint for plastic.
