The the magic they bring and the powerful way they forever changed the world, radios don’t have to be that complicated.
Joshua Made his first radio with some wire, and earphone, and a diode. He jammed one end of the wire into the ground and a breadboard. Connected that to an earphone which was in turn connected to a diode. The diode was connected to the other side of the earphone and to one more piece of wire thrown high up into a tree… the antenna. That was it!
Radio was brought to life. He could immediately hear a trumpet playing music… on the radio. No tuning required. Actually no tuning is even possible with this simple design, you hear the loudest, strongest station broadcasting. But it’s so simple! This magical arrangement of uncomplicated stuff can pull electromagnetic waves out of the thin and turn them into music.
But the best part was that immediately after hearing sound from no where, Joshua thought of nothing other than to share it with his sister.
