Build a Radio
Build a radio that can transmit morse code to any AM radio nearby!
Learn Radio Waves, Circuits, and Soldering
About This Program
There's something magical about building a radio from scratch - one that can transmit morse code to any AM radio nearby! Students build working AM transmitters on paper using foil tape traces, soldering, and simple components.
We use our award-winning Feltronics system to demonstrate how circuits work - the magnetic components on felt circuit boards make everything visible and easy to understand. Then students apply what they've learned to build their own paper radios they can take home.
What Students Learn
- How radio waves carry information
- The electromagnetic spectrum
- AM transmission and morse code basics
- Oscillators, capacitors, and transistors
- Soldering and circuit building techniques
- Paper circuit construction with foil tape
The Feltronics System
Our award-winning Feltronics approach uses felt circuit boards with magnetic components that connect effortlessly. This makes circuits visible, tactile, and easy to understand - perfect for demonstrating electronics concepts before students build their own circuits on paper.
