Homo ludens electronicus My interest in electronics started when I was 12 years old, although I had built electric devices (lighting systems, flashlights, solenoids, even a motor) much earlier. At age 12 I started the real thing: Radios, sound effect generators, light games, etc. This obsession of building things led to a career in electronics, but also it has become my most interesting hobby. I regularly design and build things, and now I will share my better documented projects with you. Each of the following links leads to a page giving constructional information (schematics, sometimes printed circuit layouts, and text) for an electronic project. Hobby projects - Simple electronic circuits Computer microphones Learn how to interface electret and dynamic microphones to the standard computer sound card. Metal detectors Theory of operation and schematics of the most common metal detectors used today: Very Low Frequency (VLF), Pulse Induction (PI) and Beat-Frequency Oscillator (BFO). Wireless microphone The wireless microphone transmitter can be built in an afternoon with simple, affordable and widely available parts.

Electronics Projects & Circuits If you've already worked through a few projects from my books; Electronics Projects For Dummies or Complete Electronics Self Teaching Guide and caught the electronics bug you might want to try a few projects from other sources. To help you out heres a list of some interesting electronics projects that we've found around the Web . These projects look interesting and are well documented but we haven't had a chance to build them all, so results may vary! We've also included links to other Web sites that contain projects you can browse through.

It contains a further 100 circuits, with many of them containing one or more Integrated Circuits (ICs). It's amazing what you can do with transistors but when Integrated Circuits came along, the whole field of electronics exploded. IC's can handle both analogue as well as digital signals but before their arrival, nearly all circuits were analogue or very simple "digital" switching circuits. Let's explain what we mean. The word analogue is a waveform or signal that is changing (increasing and decreasing) at a constant or non constant rate.

LED driving and controlling methods I decided to write this quick tutorial for two reasons: First because there are many people who would like to know more about driving and controlling LED lights, and second because i was provided an excellent LED driver chip from Farnell for test, and i wanted to put it under the microscope. So i will place this chip against some other LED drivers to see how good it is. The chip that I'm talking about is the A6210 from Allegro Microsystems. It is a Buck-Regulating LED Driver able to drive up to 3A load with constant current, with switching frequencies up to 2 MHz and supply voltage from 9 to 46 volts. It has an optional PWM input to control the brightness of the LED. The sense voltage is down to 0.18 volts for higher efficiency.

Concise electronics for geeks Copyright (C) 2010 by Michal Zalewski <lcamtuf@coredump.cx> There are quite a few primers on electronics on the Internet; sadly, almost all of the top hits resort to gross oversimplifications (e.g., hydraulic analogies), or convenient omission, when covering subtle but incredibly important topics such as the real-world behavior of semiconductors. There are some exceptions, to be sure - but they tend to suffer from another malady: regressions into mundane, academic rigor, complete with differential equations and complex number algebra in transient analysis - a trait that is highly unlikely to be accessible, or even useful, to hobbyists.
