: Circuits utilizing the LM317 or discrete transistor topologies with short-circuit protection.
Like other entries in the series, the book is organized into thematic sections to help readers find specific design ideas. These typically include: : Amplifiers, signal selectors, and filters.
Elektor began this series to provide hobbyists and professionals with a concentrated treasure trove of circuit ideas . Each book followed a strict numbering convention (301, 302, 303, etc.), with specifically representing the technical state-of-the-art for the mid-90s. elektor 305 circuits
However, I can help you in two ways:
| Category | Examples | |----------|----------| | Power supplies | Variable bench supply, battery chargers, voltage doublers | | Audio | Preamps, power amps, tone controls, VU meters | | Digital logic | Counters, timers (555), shift registers, frequency dividers | | Test & measurement | Logic probes, signal injectors, capacitance meters | | Radio/RF | FM bugs, receivers, antenna tuners | | Lighting/LEDs | Chasers, strobes, light dimmers | | Microcontrollers | Basic PIC/AVR projects (older editions) | | Sensors | Temperature, light, IR, touch switches | : Circuits utilizing the LM317 or discrete transistor
is a monument to practical electronics. It strips away the software abstraction and forces the builder to engage with the electrons. Whether you are a student looking to cement your fundamentals or a veteran feeling nostalgic for the smell of solder and rosin, this book is a must-have.
The original book provided specific copper-track layouts meant for chemical etching at home. Today, you can quickly test these circuits on a solderless breadboard or use free CAD software (like KiCad or EasyEDA) to order professionally manufactured PCBs for a few dollars. Elektor began this series to provide hobbyists and
: Tools for the electronics workbench like frequency counters or meters.
Elegant CMOS-based switches that respond to human touch.
No matter how powerful a digital processor is, the real world remains analog. A microcontroller cannot directly read a microscopic voltage change from a sensor or drive a heavy-duty actuator without an analog interface. The input conditioning, filtering, and amplification techniques found in Elektor's designs teach engineers how to prepare real-world signals for digital processing.
