Macro photography is incredibly useful, especially when it comes to shooting DIY projects. Being the thrifty folk that we are, we of course don't just pick up a maco lens off the shelf but instead look to inexpensive DIY alternatives.
Instructables user Snelpiller wanted a macro lens that would be inexpensive and easily customizable so he decided to get clever and have a little DIY fun at the same time.
To make this project you will need: a cover for your DSLR body, cover for your DSLR lens (as in a socketcover), a tube of some sort (a good suggestion is to use a gift wrapping paper roll), a hot glue gun, a Dremel or other tool for making holes in your covers, and black electrical tape.
Check out the project on Instructables for the complete instructions.
One of the great things about this project, aside from its low cost, is the ability to make the tube as long or short as you require (the longer the tube the closer the macro). A long tube with super close macro also means that your focus range is minimal which is something to keep in mind when it comes to planning your own lens project.
