Introduce Lenovo Debuts 5-Inch Vibe X Smartphone . Lenovo unveiled its new Vibe X, a fairly clear-cut smartphone, at IFA Berlin on Thursday. The 5-inch apparatus arrives with a 1,080p IPS display, a quad-core, 1.5GHz processor, a 13-megapixel camera (coupled with an oddly powerful 5-megapixel one on the front), 2GB of recollection and 16GB of storage. The specs are admirable, but they aren't the best out there. although, add in the premium polycarbonate body — which is just 6.9 millimeters thick and weighs about a quarter of a pound — and Vibe X becomes a solid lightweight competitor in the crowded 5-inch Android arena. On the programs edge, just like most of its new brethren, it sprints Android 4.2. The Vibe X will never reach European or the U.S. coastlines, we've been notified. Price and release designated day are not yet available.

This circuit operate with IC AN7156N . You just can use this IC , because hav'nt similarity it. In this Circuit have 2 input IN R and IN L and have Output R and L . Voltage supply require 15 V , minimum voltage 9 V and maximum voltage 24V . And the voltage must DC voltage , and better the DC voltage filtering . Maximum Output for 1 speaker 25 W , so this circuit have maximum output 2 X 25 W with minimum impedance 4 ohm. See this circuit schematic below : Click image to view enlarge

The above is a stereo amplifier circuit based on IC STK4191 with 2 X 50Watt output power 8 ohm impedance. And besides that you can use some of the IC can also be applied in this series include the STK4101, 4111, 4121, 5131, 4141, 4151, 5161, 4171, 4181, and 4191. Required supply voltage from 12 Volt to 35 Volt DC. Part List : R1 = 22K R2 = 22K R3 = 560R R4 = 56K R5 = 1K R6 = 1K R7 = 100R R8 =  2K R9 = 2K R10 = 4.7R R11 = 2K2 R12 = 2K2 R13 = 4.7R R14 = 100R R15 = 56K R16 = 560R C1 = 0.1uF C2 = 0.1uF C3 = 100uF C4 = 100uF C5 = 100uF C6 = 0.1uF C7 = 47uF C8 = 47uF C9 = 0.1uF C10 = 100uF C11 = 100uF U1 = STK4191

Do not misunderstand, this series is one of several series of power amplifiers that have output / low output power. This amplifier output is only possess more or less 4Watt. Or 2 X 2Watt stereo power amplifier. Minimum required voltage is not less than 3 volts and a maximum voltage of no more than 14 volts, and voltage must be rectified and filtered to obtain the maximum of the processed audio. Component List : R1 = 2,7R R2 = 2,7R C1 = 1uF C2 = 1uF C3 = 100uF C4 = 220uF C5 = 100uF C6 = 100uF C7 = 220uF C8 = 0.1uF C9 = 0.1uF C10 = 470uF C11 = 470uF U1 = ULN3750B

A protector system that is applied at the beginning of the television technique, therefore most often found on old aircraft models. If the high voltage anode of the picture tube flyback tranfo exceed the permitted limit, the picture tube can generate x-rays from the anode and shadowmask are bombarded by electrons at high speed. To avoid this problem then mounted x-ray surge protector circuit , which automatically "horizontal section will be turned off" if the high voltage from the flyback over. X-Ray vertical protect The workings of x-ray protector: High voltage flyback sampled (generally taken from the pin-heater), rectified and is derived using a divider (devider) that uses a resistor-type high-precision resistor. Sample voltage is used to determine whether the condition is normal flyback voltage or over. A "zener diode" as a voltage sensor connected to the sample. In normal conditions the amount of the sample voltage is below the zener voltage of diode so that th...

Audio amplifier circuit is very suitable for use at home, using a subwoofer speaker, or woofer speaker. Usually, also called home amplifier, audio amplifiers are based on the IC and ic are used still in series with type STK457 STK and besides it also can use the STK459, 460, 461, 463, 465. And each ic has the quality of each one, please look at alldatasheet.com. Part List : R1 = 22K R2 = 22K R3 = 330R R4 = 33K R5 = 1K R6 = 1K R7 = 4.7R R8 = 3K3 R9 = 3K3 R10 = 4.7R R11 = 100R R12 = 33K R13 = 330R C1 = 0.1uF C2 = 0.1uF C3 = 100uF C4 = 100uF C5 = 0.1uF C6 = 47uF C7 = 47uF C8 = 0.1uF C9 = 100uF C10 = 100uF U1 = STK457,STK459, 460, 461, 463, 465.

Amplifier circuit here is all based on the ic in the gains. Three IC TA7230P, TA7236P, TA7237AP is intregated circuit (IC) which was applied to the power amplifier. Each IC has a different output, different input voltage, all IC TA7230P, TA7236P, TA7237AP is manufactured by Toshiba. TA7230P, TA7236P, TA7237AP amplifier schematic

Minimum Voltage required for this circuit  8 volt and maximum voltage 28 volt . Its can use to amplifier on the electronic devices such us Radio , DVD , MP4 , MP5 , and etc. To amplify the signal sound to audio sound , Maximum output power 2 x 20 Watts with impedance 4 ohm. The circuit is stereo amplifier. You can use the circuit to car amplifier because support to subwoofer speaker. See schematic diagram below :
