Diodes wat is a diodes soldered in a diamond formation? and how can it convert ac to dc power?
I just need help in eletronics!!! and wat website teachs like people who want to know about eletronics things like simple things?
4 diodes in a diamond is usually a diode bridge, also known as a rectifier. It takes the 360° of AC and converts it to 2 180° positive going phases. You'll usually find a capacitor and resistor on the output of the diodes to smooth the output and give you DC with as little ripple as possible.
A library is a great place to learn, also try searching the web for basic electronics.
Here's a decent site to get a grasp of electronics. It it captured from NEETS Mod, or Navy Electricity and Electronics Training Series Module. http://www.tpub.com/neets/index.htm You can click on the book name to view in html format(the first book is named NEETS, MODULE 01--INTRODUCTION TO MATTER, ENERGY, AND DIRECT CURRENT), but have to pay to download the whole book at a time(which is dumb because all of the information is in html anyhow). NEETS Mods are nice because they give you the information, then test you, and you have the answers at the end. When you read though and see "Q.1" that means question 1 and you should try to answer it. It will really help get a grasp on basic electronics. It is geared towards teaching the typical sailor basic electronics, which means even a chimp should be able to learn from these books, I did
High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).

In this book, I have optimized the growth of n and pGaN films, and high quality InGaN/GaN multiple quantum wells (MQWs) on sapphire (0001) substrate by a low pressure metalorganic chemical vapour deposition and have fabricated high brightness InGaN/GaN MQW lightemitting diodes (LEDs) under optimum conditions. To improve quantum efficiency which is generally poor in the conventional rectangularshaped QWs due to spatial indirect recombination induced by internal piezoelectric field, we proposed a possibility of quantum dot (QD) engineering with triangularshaped band structure in the InGaN/GaN QWs. The structural and optical properties of the InGaN/GaN MQWs with different threading dislocation densities were also investigated. The effects of Sidoped nGaN and Mgdoped pGaN layers on the electrical and optical properties of the InGaN/GaN MQW LEDs were investigated and optimized under various growth parameters.

Organic lightemitting diode (OLED) technology is used in a variety of display applications, ranging from cell phones and MP3 to prototype TVs, and holds great promise for the production of highly efficient largearea light sources and flat panel displays. It has the potential to become a multibilliondollar industry within a few years. The biggest technical challenge for OLEDs is the limited lifetime associated with elevated temperatures and exposure to moisture. The guaranteed hours of operation (15,000 hr) is currently inadequate for most TVs and replacement of LCDs with the 60,000 hr halflife. This book, therefore, investigated the thermalactivated and moistureinduced degradation pathways of small molecule based prototype OLEDs as well as interfacial electronic properties at the nanoscale level through realtime visualization. The results should help shed some lights on improving luminescence efficiency and lifetime of OLEDs, and should be especially useful to professionals in research and development of not only OLED technology but other organic electronics, or anyone else who may be interested in plastic electronics.

Revised and fully up-dated, the second edition of this graduate textbook offers a comprehensive explanation of the technology and physics of LEDs such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III-V semiconductors. Elementary properties such as electrical and optical characteristics are reviewed, followed by the analysis of advanced device structures. With nine additional chapters, the treatment of LEDs has been vastly expanded, including new material on device packaging, reflectors, UV LEDs, III-V nitride materials, solid-state sources for illumination applications, and junction temperature. Radiative and non-radiative recombination dynamics, methods for improving light extraction, high-efficiency and high-power device designs, white-light emitters with wavelength-converting phosphor materials, optical reflectors, and spontaneous recombination in resonant-cavity structures are discussed in detail. With exercises, solutions, and illustrative examples, this textbook will be of interest to scientists and engineers working on LEDs and graduate students in electrical engineering, applied physics, and materials science.

diodes in circuits and testing them
How can I increase DC voltage in a circuit using diodes and capacitors?
I've heard that there's a way to do this, but I'm not real good with electronics...
If you are starting with DC you will need more than just capacitors and diodes, if you start with AC, a voltage multiplier can be used; http://en.wikipedia.org/wiki/Voltage_multiplier
Starting with DC you will have to convert to a pulsating current (pseudo AC) which will require additional components, probably some transistors or an IC oscillator. There are commercial DC to DC converters available ready made.
