Razor 2
Here’s how to make a fantastic (and simple) AM radio, Grendel – “I just finished making quite possibly the world’s most simple radio. I had read a few HOWTOs for constructing a crystal radio. Some links offered the basic formulas for figuring the specs needed for the coil if you wanted to tune various frequencies. I purchased 3 spools of “Enamel-Coated Magnet Wire” from Radio Shack for ~$5, and picked up a crystal ear piece while at EPO in Houston.” [via] – Link.
