A classic "fun" project. Using a microphone, a tone decoder (the famous LM567), and a flip-flop, this circuit lets you turn a lamp on or off by whistling. This is the grandfather of modern "clap switches." As a teaching tool, it demonstrates frequency filtering and audio amplification beautifully. : Includes schematic diagrams, component lists, and brief

: Circuits for measurement and control applications, including timers, counters, and sensor interfaces.

Unlike today's 0402 SMD components that require a microscope, the Elektor 305 circuits use DIP chips, resistors with color bands, and capacitors you can actually see. They are perfect for breadboarding, stripboard (Veroboard), or custom PCBs made with a laser printer (toner transfer).
