Actually, 5.1 channel amplifier consists of 6 amplifiers 1 channel mono, which has certain specifications on each canals. Has 6 channel surround sound amplifier that consists of Front Left | Center | Front Right | Rear Left (Left Surround) | Rear Right (Right Surround) | and LFE (Subwoofer). For clarity I give a simple illustration of the layout and the circuit for these speakers. 5.1 Speaker Setup Accoustic Field Generator Acoustic Field Generator is generating acoustic sound with surround effects are adjustable with a standard Dolby Surround, able to produce surround sound is good enough but not too much need of funds. Technological developments as if not only focused on one area alone but on all fronts. The development of technologies that exist today one of them is in the field of audio. With more advanced audio technology today not only as mere entertainment but has become a hobby, hobby is not cheap of course. Many audio enthusiasts trying to make music sound t...

This simple flash you is very compact build in a brooch for example. I have the circuit extracted from a CD cover.  1.5 V LED Flash Circuit Schematic Diagram The flash uses a 1.5 V supply, this is a penlight or use a button cell. Capacitor C1 controls the flash frequency within certain limits. The declared value of C1 is the frequency about 1.3 Hz. parts List C1 = 100 uF D1 = Low current LED IC1 = LM 3909

How to make printed circuit boards, 1 Firstly, we are to draw a circuit with a design program. There are many great programs, you just have to browse for them a little on the Internet and see which one fulfils your necessities. The program we’ll be using is called “Eagle”. It’s a great design program that also has Mac and Linux versions; there is a “light edition” that can be downloaded for free, with size limitations - it can only make 10x8 cm boards. All designs from this web page are made with that version. It is quite enough at the household level. Therefore, we’ll begin with a prototype made with this program. Necessary material: -A program for circuit design, in this case, “Eagle”. -A printer, if it’s laser, even better; normal printer also works fine, but later you’ll have to make a photocopy. -Glossy photograph paper (Epson photo quality, 140g/m2 or similar) -A board of a printed circuit (glass fiber), dual layer in this case. -A solvent. -A plastic container where we can...

It is a simple circuit of optical index of level of sound signals, adapted in various needs of user. It can be adapted in various levels of entry, regulated from trimmer TR1 (Level) - TR2 (Gain), then it is rectified by the D1-2 (cutting off of negative periods of signal-rectification) and drived to the main circuit of index, that it is constituted by D3...D13 , the transistors Q2-Q13 and the materials that exist around them. Circuit Diagram:  The optical index him we take from the line of LED LD1-13. The each led turns on when the level is altered at 0,65V roughly. The requirements in current are 100 ma with complete index. We can add all units LED we want, always calculating the current where they will need the news LED. Parts List:

The Mantis 9.1 design is a radical departure from version 8 and earlier. Most notably, the part count has been almost halved! The current design has 13 parts, all of which can be made with a handsaw and a drill press. Also, I’ve traded away my alignment free exactly-constrained design for extra stiffness. Several unsuccessful attempts to eradicate the last of the slop in the Z axis on version 8 lead me back to the world of over-constrained parallel rods. My previous attempts at an over-constrained design (versions 1-5) all failed because I was unable to make the rods sufficiently parallel to avoid jamming. What to do? [ ]

Thanks to their high light output and long lifetimes, a white LED is an excellent choice as a replacement for the incandescent bulb in a penlight torch. However, there is a ‘but’. Depending on the current level, white LEDs need a voltage of 3 to 4 V. You thus need a penlight with at least three batteries, which is not exactly what you can call compact. Fortunately, this problem can be remedied using a simple adapter circuit.   The design described here allows a white LED to be operated from a single 1.5-V battery. It consists of a simple step-up converter and an oscillator. If the circuit is built using SMD components as much as possible, it will not be difficult to fit everything into the torch.  The actual step-up converter consists of L1 and T1. The coil is wound on an EP7 core, which consists of a spool, two core halves (T-38 core material) and a clip/screen. It is available from Farnell, among others. Wind 17 turns of 0.5-mm enamelled copper wire on the spool. If you make the wind...

PIC16F887 and PIC16F877 are the members of PIC16F88X and PIC16F87X families respectively. PIC16F887 is the new version launched by microchip to take place of PIC16F877.For detail information please refer to their datasheets. In this tutorial i will show you how to program PIC16F887/877 in C. So first of all download mikroc pro for pic compiler also download its user manual. After this create a new project choose P16F887 or 877 whatever you have, and 4MHz crystal etc. If you dont know how to create a new project refer to its manual or download document 'how to create first project' from its site. Note that i will use PIC16F887 and 4MHz external crystal (although PIC16F887 also have internal crystal) you can use 8MHz and what so ever. For 4MHz oscillator setting should be XT where as for 8MHz or above it should be HS (see fig below). Lets start with a simple program 'LED Chaser', before we start this lets check out the PIC16F887 pin out. pinout of pic16f887 As you can se...

Introducing the C-1, the world’s first gyroscopically-stabilized “rolling smart phone”. This vehicle combines the efficiency and freedom of a motorcycle with the safety and convenience of a car. Offering the “alternative to alternatives” on an exciting and safe platform, the C-1 transforms your daily commute into something to look forward to. Influenced by Scandinavian design, the exterior of the C-1 is both approachable and simple, enveloping the human in subtle curves, softened volumes, and lots of glass. The overall design foundation is based on its waist line, which wraps around the vehicle’s circumference, and is grounded by the swooping rocker panel, highlighting its unique gyroscopic components. Discs of light glow from the wheel hubs, illustrating the electric hub motors. With design key words: “subtle”, “simple”, and “human”, the C-1 is as happy to be seen as it is to be touched. The C-1 was designed with you in mind. Lit Motors’ human-centered approach to design makes sure th...

It's a little wisp of a circuit that allows you to drive a blue or white LED from a low voltage. Normally, if you want to light up a blue or white LED you need to provide it with 3 - 3.5 V, like from a 3 V lithium coin cell. But a 1.5 V battery like a AA cell simply will not work. But using the Joule Thief, it works like a charm. Not only does it work with a brand new battery, but it works until the battery is nearly dead-- down to 0.3 V. That's well below the point where your other toys will tell you the battery is dead, so it can steal every last joule of energy from the battery (hence the name). To learn how to make one, watch the video, which is available in a variety of formats.
