J A Ollinger sent in one of my favorites projects from Sci-Toys in, building a crystal radio out of household items –

“Step-by-step instructions on how to build simple radios using common household goods. This is part of a larger section on building simple radios, but this page was particularly interesting (like how to make a capacitor out of tin foil and wax paper).” – Link.
