The CDROM Crystal Radio

Published on 2005-12-16 by Mark VandeWettering

I’ve had this project in a pile of bookmarks that I was sorting through, and am linking it here so that I can find it again sometime later: H. P. Friedrich has nice design for a crystal radio build from stuff a computer person might have around the house. Interestingly, he even makes the variable capacitor that forms the heart of crystal radios. Good stuff.
