Many middle-aged DIY enthusiasts have constructed a crystal radio set; it’s such a joy to pull radio signals out of the ether using only the radio signal itself for power.

Unlike traditional crystal sets, the XS-402 uses a molded, high frequency choke, eliminating the frustrating coil-winding process, and features large solder pads, great for learning to solder. It’s a perfect project for adults to build with kids, and it serves as a great tool to teach basic radio theory, soldering, and handling of electronic parts and PCBs.  If you’re interested in “old school” radio technology or want to learn more complex skills, this is the kit for you.
