FM transmitters can be complicated to build, but not this one — it's about the easiest you can possibly make. And though the science of radio is well understood, there's a magical, emotional quality about it that we don't often stop to appreciate. Building your own radio receiver — or better yet, transmitter — makes it real again. You will not forget the first time you pick up a transmission broadcast from a device you soldered together, yourself, from a few bits of copper, carbon, plastic, and wire.
