Electronics is the science of how to control electric energy, energy in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive electrical components and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.
The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible, and electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working system.
An electronic musical instrument is a musical instrument that produces sound using electronics. Such an instrument sounds by outputting an electrical audio signal that ultimately drives a loudspeaker.
An electronic instrument might include a user interface for controlling its sound, often by adjusting the pitch, frequency, or duration of each note. However, it is increasingly common to separate user interface and sound-generating functions into a music controller (input device) and a music synthesizer, respectively, with the two devices communicating through a musical performance description language such as MIDI or Open Sound Control.
All electronic musical instruments can be viewed as a subset of audio signal processing applications. Simple electronic musical instruments are sometimes called sound effects; the border between sound effects and actual musical instruments is often hazy.
Electronic musical instruments are now widely used in most styles of music. Development of new electronic musical instruments, controllers, and synthesizers continues to be a highly active and interdisciplinary field of research. Specialized conferences, notably the International Conference on New Interfaces for Musical Expression, have organized to report cutting-edge work, as well as to provide a showcase for artists who perform or create music with new electronic music instruments, controllers, and synthesizers.
Treasure (from Greek θησαυρός - thēsauros, meaning "treasure store",romanized as thesaurus) is a concentration of riches, often those that originate from ancient history, considered lost and/or forgotten until being rediscovered. Some jurisdictions legally define what constitutes treasure, such as in the British Treasure Act 1996.
The phrase "blood and treasure" or "lives and treasure" has been used to refer to the human and monetary costs associated with massive endeavours such as war that expend both.
Searching for hidden treasure is a common theme in legend; treasure hunters do exist, and can seek lost wealth for a living.
A buried treasure is an important part of the popular beliefs surrounding pirates. According to popular conception, pirates often buried their stolen fortunes in remote places, intending to return for them later (often with the use of treasure maps).
There are three well known stories that helped popularize the myth of buried pirate treasure: "The Gold-Bug" by Edgar Allan Poe, "Wolfert Webber" by Washington Irving and Treasure Island by Robert Louis Stevenson. They differ widely in plot and literary treatment but all are derived from the William Kidd legend. Stevenson's Treasure Island was directly influenced by Irving's "Wolfert Webber", Stevenson saying in his preface "It is my debt to Washington Irving that exercises my conscience, and justly so, for I believe plagiarism was rarely carried farther.. the whole inner spirit and a good deal of the material detail of my first chapters.. were the property of Washington Irving."
A church treasure (German: Kirchenschatz) is the collection of historical art treasures belonging to a church, usually a monastery (monastery treasure), abbey, cathedral. Such "treasure" is usually held and displayed in the church's treasury or in a diocesan museum. Historically the highlight of church treasures was often a collection of reliquaries.
As a result of gifts and the desire to acquire sacred artifacts, many churches over the centuries gathered valuable and historic collections of altar plate, illuminated manuscripts of liturgical or religious books, as well as vestments, and other works of art or items of historical interest. Despite iconoclasm, secularism, looting, fire, the enforced sale of treasure in times of financial difficulty, theft and other losses, much of this treasure has survived or has even been repurchased. Many large churches have been displaying their riches to visitors in some form for centuries.
Treasure is a limited edition compilation album by Holly Cole Trio. It was released in Canada in 1998 on Alert Records. It is a collection of "Hits and Previously Unreleased Tracks" from 1989-1993.

Kit build of a $5 electronic metal detector. The unit works, but only when metal objects are placed very close to the coil. Purchased here: DIY Kit Simple Metal Detector Metal Locator 3V-5V DC Electronic Production Good http://www.ebay.com/itm/-/131252426069 Some modification ideas here: http://www.talkingelectronics.com/projects/200TrCcts/MetalDetectors/MetalDetectors-1.html
+/- 1000¥ = $9 So you can buy used games for a buck and Playstation 2 for about $26 They have original Vinyls too. You can also find great selection of old amplituner and speakers. Laptops are not so attractive by price but tablets you can find interesting. I notice lots of junk but there are diamonds for example a "new alike" original NES with all accessories included. The cheapest things are under "JUNK" section and they are without warranty and with "no return policy", often without any accessories like ac adapter etc.

It is passed through this stream and is also used as a treasure sign. We will follow the direction of the stream to see if it will guide us to something.
