Step 2: What You'll Need
- Full-page Fresnel Lens
Cardboard: I got my cardboard box at a Wal-Mart. I just went into the photo-lab area and asked if they had any boxes I could use for a project. They had more than they cared to have! I chose one that was a couple feet long, and the front face was just larger than my iPad.
Tape: For tape, I got black Duck Tape (also from Wal-Mart), but even packing tape or masking tape can work just great!
Fresnel Lens: I found my Fresnel lens on eBay for about $3.99. Since then, I've seen them as low as $2.99. The size is somewhere around 8"x10". These are typically used as full page magnifiers for reading small text.
