Related:  Electronics (Электроника) - Radio Building a simple crystal radio. A crystal radio is the distilled essence of a radio. It has very few parts, it needs no batteries or other power source, and it can be built in a short time out of things you can find around the house. The reason a crystal radio does not need any batteries is the amazing capabilities of the human ear. The ear is extremely sensitive to very faint sounds.

Digital Camera Interface Iñaki Navarro Oiza Report ::: Code ::: Slides Introduction The aim of this project is the development and construction of an interface between a CMOS camera and a computer. This interface allows a user to get images from the camera, to change some of the properties of the camera as brightness, luminance, etc from a computer. Chapter 10: Computers and Electronics A simple 1 watt audio amplifier The solderless breadboard makes it easy to experiment with additions to the radio circuit. In this section, we will build a simple amplifier, so that a whole room can hear the radio through a speaker. Our amplifier will not be ear shattering, since we have made it as simple as we can to build, but the output is pretty impressive for a single transistor.

Circuit Simulator Applet This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. - Computers and Electronics Building a computer controlled radio transmitter How would you like to send text messages to your friends without wires, and without an Internet connection, and without paying monthly fees? In this project we will build a very simple radio transmitter that you attach to a serial port on your computer. The computer then runs a free program that converts words you type into radio signals that are decoded by another computer, using a cheap radio receiver, and a sound card. With a little study, you don't even need the second computer, since the radio signals are in Morse code, which anyone can learn to decode in their head with a little practice. It also comes in handy as a secret language, or as a way to send long distance messages with a pocket mirror.

blog: HOW TO - Getting Started with Arduino I’ve compiled a brief tutorial on getting started with Arduino for the absolute beginner. I’ll cover where to learn, what to buy, and where to go for help. Why should you crafters be interested in Arduino? The Arduino platform, more-so than any other way of incorporating electronics into your projects, is geared towards do-it-yourselfers. It’s open source (both on a hardware and software level), so the community plays a large role in its development and improvement.

Evil Mad Scientist Laboratories - Resources for getting started This is a short list of resources for getting started with AVR microcontrollers. It’s intended as a supplement to intro AVR classes that we have given. We intend to periodically update this list; leave your suggestions for additions in the comments, please. 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. You are welcome to use this information for educational purposes and for your own use, but please be honest enough not to make business with them.

The Arduino project gets a core memory accessory A pair of mathematicians have created an electronics project that nostalgic computer buffs will likely recognise straight away: a magnetic-core memory shield for the Arduino electronics prototyping platform. The Arduino is an open-source development system for the creation and programming of electronic gadgets. Powered by an ATMega microcontroller, it's a popular platform for both experienced developers and newcomers to the hobby - and has been chosen by Google to form the heart of its Open Accessory project for Android. Perhaps the biggest attraction for the project is the availability of 'shields' - add-on circuit boards which connect to the Arduino and add new facilities such as screens, joysticks, sensors, or even Ethernet connectivity. A pair of mathematicians have created possibly the nerdiest shield yet, however - one that stores a tiny chunk of data on the height of 1950's technology: core memory. "No, that's a joke.
