[WATCH]: lost in a blak box -analog synthesizer elektro

Rating: 5
4 minute snip of a 25+ minute live analogue session elektrobahn is a studio and live performance project that works completely with old school cv gate and pre-first gen midi. all the vintage gear that’s in the rack you see here and on elektrobahn.com is pre 85. the moogerfoogers, dp4 and orb sequencer (which has switched out to a doepfer maq) obviously are not vintage, so we bent the rules a bit. in the studio we employ a couple of tape echos, mutrons and other old stomp boxes. the point of the project is sentimental in regard to a fascination with the simplistic mechanics of old gear, modulated with the aesthetics and sonic sensibilities of the 21st century. its very much a modular approach which is popular again. everything is multi track recorded in one pass to a computer. there is no manipulation of the sequence. it’s eq’d and slightly compressed. why, you ask? to some, this might seem tedious, and too simple to achieve a well rounded track. to us, the focus is it’s simplicity. it’s about interesting harmonics and the strange behavior of circuits and it’s effect on air molecules as they beat the shit out of the studio/gallery/warehouse walls… gear heard on this recording: korg ms10, korg sq10, moogerfooger fx, roland tr-808, akai ax60, akai s612, moog memorymoog, ensoniq dp4 www.elektrobahn.com

The World of Fiber Optics

Principle of fiber optics is based on transmission of data by means of light. Concept of fiber optics was first conceived by Claude Chappe in 1790′s. His idea for fiber optics was based on an optical telegraph concept invented by Graham Bell also tried the means to send information by the atmosphere but did not succeed. Finally, fiber optics emerged with the onset of new era based on the principle of total internal reflection which is a distinct quality of light rays.

fiber optics emerged and grew into more advanced phase due to requirement from radio and telephone engineers. These engineers required more bandwidth for data transmission. Thus these engineers had been looking out for a medium to transmit data in more reliable and faster form rather than copper cables. They also wanted to avoid the hazards of electric shocks and interference which were a constant problem of copper cables.

fiber optics had attracted some attention because they were analogous in theory to plastic dielectric waveguides used in certain microwave applications. Finally a technology evolved that used glass or plastic threads to transmit data. Cables involved in fiber optics contain several bundles of glass threads which are capable of transmitting data in modulated form.

With the onset of fiber optics and fiber optic cables data started to transfer faster as fiber optic cables have greater bandwidth than metal cables and are more resistant to external interference. Lighter and thinner fiber optic cables readily transfer data in digital form rather than analogue form. This technology is most useful in computer industry which now forms an integral part of telephone, radio and television industry.

Telecommunications applications of fiber optics use flexible low-loss fibers, using a single fiber per optical path. Along with the communication industry fiber optics plays an important role in medical and industrial applications also. Many medical appliances like endoscope use the principle of fiber optics. Industrial applications viz. in television industry use the principle of fiber optics to obtain flattened images in cathode ray tubes.

fiber optics yield distortion free data transmission in digital form. The audio waves transmitted via principle of fiber optics deliver accurate signal transfer. fiber optics is also useful in automotive and transportation industry. Traffic lights, organized and scrutinized highway traffic control, automated toll booths, etc. are some of the benefits of application of fiber options in the transportation mechanism.

Cable TV companies and Internet Service Providers equivocally find fiber optics indispensable in their industry. fiber optics provides tamper free, high bandwidth and larger data carrying capacity to the service providers. This eventually leads to better consumer satisfaction.

Unlike copper wire system fiber optics do not use and electrical form to carry data. The use of light gives a competitive edge to fiber optics over regular data transmission options. But eventually use of fiber optics is very expensive as compared to copper cabling system.

Borescope Viewer W-Light 18″, 36″

The borescope Viewer w/Light can help locate objects, illuminate dark spaces and provide an efficient way to complete a variety of tasks without any demolition or disassembly.

How Does the borescope Viewer w/Light Operate?

Using fiber optic technology, the flexible borescope can help you look behind walls, into drains, engines or vents, and any other place that would ordinarily require a lot of labor or demolition to examine. The powerful halogen light can illuminate the darkest spaces, and the high resolution lens allows for a clear view of objects over one foot away or as close as ? of an inch! Additionally, you’ll have a large 40 degree viewing field to help make the job even easier.

What is the borescope Viewer w/Light Made From?

The durable borescope is made from high impact ABS and flexible cable sheathing that will stay in the position you want it to be in. Simply adjust the cable to your desired viewing angle and it will stay in place until you decide to change it. Plus, it’s water resistant and can handle a variety of even the toughest tasks.

What are the Features of the borescope Viewer w/Light?

This device includes a number of convenient features, such as:

- Can reach into holes as small as ? inch in diameter

- Cable will maintain a set position until YOU readjust it

- The flexible cable will bend in any direction to help you examine drains, walls, vents, etc or illuminate dark spaces

- Pressure activated light switch can never be accidentally left on

- Ergonomically designed handle with no-slip grip; also allows for one-handed operation

Whether you need to illuminate dark areas; look behind walls or into vents or engines or simply troubleshoot a problem, the borescope Viewer w/Light can help you examine even the tightest spots without any demolition.
