Electronics project with my son
Will's latest electronics project is a simple circuit for recording and playing back sound:
Previously he built a working transistor radio (MW receiver set) using a variable resistor, added an amplifier, then converted it into a self-tuning FM radio. He built the transistor radio and the circuit shown in the video (above) without any help by following the circuit diagram and instructions.
This excellent elecronics kit is "Hot Wires" by John Adams -- highly recommended!
