Have you ever wondered how a radio picks up waves and converts them into a sound you can hear?
Find out for yourself with this build it yourself Crystal Radio set from Artec!

These radios are completely built by hand, and require no outside power source.

Experience the past, take yourself back to 1904 when these were first invented! This style of radio was extremely popular in the early days when radio was just making headway. Running purely off of radio waves, this radio isn't terribly powerful, but will give you a great understanding of how radios work, and you can use it any time, anywhere. (well, anywhere there are radio signals, anyway!)

The design of this radio is very similar to the antiques of the past, with only a couple of small changes, like the compact crystal detector instead of a full sized “Cat's Whisker”, and the addition of a modern diode.

If you'd like, you can even design and build your own fancy wooden base for a truly authentic looking model! (Steam Punk, anyone?) We'd love to see what you do with this kit, feel free to submit your project photos, and we can feature them on the site if you'd like! 🙂

IMPORTANT! Small parts, keep away from small children!

Discover the Fundamentals of Radio

Crystal radios are known as being a “passive receiver”, meaning that a crystal radio is powered entirely by the radio waves that it receives. Therefore the signal it receives, as well as the sound produced is fairly weak, and it can only pick up a limited number of stations. The only way to hear the sound is by extremely sensitive earphones and a cat’s-whisker detector (also know as a crystal detector). It is an antique electronic component consisting of a thin wire that lightly touches a crystal of semiconducting mineral, galena to make a crude point-contact rectifier.

Modern radios run on electricity that seriously amplifies the signal, allowing you to tune in to a huge amount of stations, and also gives a huge boost to the clarity of sound, and the volume which can be produced. That said, what is more awesome than not having to use external power?
