This is the schematic diagram of 3 channels audio splitter amplifier circuit which built using op-amp IC TL084. The 3 channels amplifier output distribution applies a single TL084.   3 Channels Audio Splitter Amplifier Circuit Diagram The very first step is to capacitive coupling having a p. 1.0 ~ electrolytic capacitor. The entries are railways Vee Y2 or 4.5 V. This enables working with an individual 9V power source. A voltage gain of 10 (1 M?/100 Kohm) is obtained in the first stage, as well as the other three floors are connected as a unity gain voltage followers. Every single output stage drives independently through an amplifier output 50 pF capacitor towards the resistance of 5.1 k ohm load. The response range is flat from 10 Hz to 30 kHz.

This is a very simple build Electronic Circuit Project of single solar cell trickle charges 3- to 16-v battery in-circuit.   Many battery-powered applications use very little power when idle and have short-duration operating periods. Thus, the total energy used is very small. It would be convenient to incorporate solar cells in these devices to charge the batteries. However, the number of cells needed to charge a given battery voltage is close to Vb/0.6, thereby necessitating an array of solar cells, series connected. Single Solar Cell Trickle Charges 3- To 16-V Battery in-Circuit: The circuit in the figure addresses that issue by employing a self-oscillating boost circuit operating from a single solar cell. As such, it's able to trickle charge the battery continuously. The solar cell charges C2 until there's sufficient voltage to activate Q2. This will cause the output of U1a to turn on and latch on through the action of U1b. U1a's output also turns on Q3, which begins tra...

It is expected that Samsung present its new phone Samsung Galaxy Note 4 officially in September during IFA 2014 event held in Berlin, Germany. Now, the Korean media already have an exact date of this phone Samsung. According to The Korea Times, Samsung will be announcing the Galaxy Note 4 on September 3, a day before the presentation of the Galaxy Note 3 last year. Samsung is expected to start sending invitations to the event "soon", including that the company would be a bit rushed to launch its new mobile big screen because Apple is finally breaking its tradition of offering only one size cell relatively small as the iPhone 6 to gain entry to the high-end market. It is said that Samsung is trying to get the Galaxy Note sale 4 days before what went on Galaxy Note 3 with this same purpose. It is expected that the Samsung Galaxy Note 4 has a QHD (2560 × 1440) 5.7 inch screen, a Snapdragon 805 / Exynos 5433 processor, 3GB of RAM and a 16 megapixel camera that would include th...

In industrial processing operation there are cases where machineries should be started one after the another. One example of electrical control applied to machineries in a processing operation is the sequential control shown in figure below (A) and (B). The 3 motors; M1, M2 and M3 are drive mechanical machine. Motor M1 is first started. After a Pre-set time, Motor M2 is started automatically. Later, with another pre-set time, motor M3 is started. Control Operation The first stage of control operation is started by pressing the start push button switch shown in figure 16 (a). Contactor C, timer TR1, and pilot lamp A are energized. Contact C1 (13-14) will close to maintain contactor C, timer TR1, and pilot lamp A. Contacts C2 (1-2,3-4,5-6) will also closed to energize and operate the motor M1, see figure 16 (b). Likewise the instantaneous timer contact TR1 (1-3) will close to prepare the second stage of operation (A) Control circuit of 3 stages       sequential Control. After the pre-set...

3 Band Tone Control circuit uses an op-amp as an amplifier end. Tone Control circuit is a regulator of tone bass, midrange and treble or 3 band called because it can set the three tones. Filter circuit is applied to the series of "Tone Control 3 band" This type baxandal like the title of this article.  Results filtering regulator tone or tone control baxandal type is good, because there is no signal level is wasted directly into the ground. Range frequency tones generated from Tone Control 3 band was determined by the configuration of the R and C of the filter section baxandal. As an amplifier on Tone Control The set of three band use traditional IC LF351 has slewrate high and high input impedance. For more details, series 3 Band Tone Control as follows. Figure Series 3 Band Tone Control 3 Band Tone Control circuit above using LF351 Op-Amp is used to strengthen the signal after filtering by the filter process baxandal.

I am quite sure that many of us have attended our fair share of trade shows and conferences over the years that we have amassed quite a collection of USB flash drives in our homes, so much so that these have become not valuable at all compared to the early days when a 32MB USB flash drive was all the rage, and hitting 1GB was like, “Whoa!”. Well, we just love the way that technology progresses over time, and here we are with the Kingston HyperX PREDATOR which offers a whopping 1TB of storage space, and fret not about spending huge amounts of time whenever you transfer data to and from it, as it will feature USB 3.0 connectivity to get the job done as fast as possible. Having the Kingston HyperX PREDATOR around is definitely a boon, especially for those of you who do plenty of traveling and yet need to carry a portable hard drive around. The physical dimension of it is extremely small compared to even the smallest 2.5” portable hard drive around, although the latter has now achieved the...

The circuit diagram shows a low-cost 3-input video MUX cable driver. In this circuit, the amplifier is loaded by the sum of RF and RG of each disabled amplifier. Resistor values have been chosen to keep the total back termination at 75 Ω while maintaining a gain of 1 at the 75-Ω load. The switching time between any two channels is approximately 32 ns when both enable pins are driven. When designing a circuit board for this cable driver, care should be taken to minimize trace lengths at the inverting input. The ground plane should also be pulled away from RF and RG on both sides of the board to minimize stray capacitance. Current consumption of the cable driver is a modest 8mA.

Normally, when we talk about an Android-powered system, we would venture into the realm of smartphones and tablets, and very rarely (if ever) into the world of digital cameras. The line is about to be blurred this day, as the Nikon Coolpix S800c was just announced to come with a copy of the Android operating system – Android 2.3 Gingerbread, to be exact. Yes sir, how does this digital camera shape up in the face of a mobile operating system running in the background? Well, we shall have to take a closer look at its machinations and inner workings right after the jump, shall we not ? For starters, with Android running on the Nikon Coolpix S800c, you might actually feel that you are using a smartphone at times – until you realize that you are unable to make any phone calls or receive text messages. Good thing it has Wi-Fi connectivity built in though, as it would not be much of an Android device if there were not Internet connectivity to make it interactive. Setting up the camera for Int...
