This Circut based on IC TDA7231 , Minimum voltage require 2 Volts and maximum voltage 15 volts . I recomended voltage is 12 volt DC. Power output 1,6 Watt with 4 Ohm impedance. See audio amplifier with IC TDA7231 below :

Power supply circuit to generate output below were variations between 1.3V DC to 12.2V DC with 1A current. In addition, the power supply circuit is also equipped with over-current protection or shield against belebih flow. Power supply circuit is very simple, but the quality is quite good, made her basiskan regulator IC LM723 is a pretty legendary. Description: R2 to set the output voltage. The maximum current is determined by R3, over-current protection circuit inside the LM723 to detect the voltage on R3, if it reaches 0.65 V, the voltage output will be off her. So the current through R3 can not exceed 0.65 / R3 although output short-circuit in his. C3 and C4 are ceramic capacitors, as much as possible directly soldered to the PCB, this is because the LM723 is prone to oscillation that is not cool. LM723 works with 9.5V input voltage to 40 V DC and the LM723 can generate its own current of 150mA when the output voltage is not more than 6-7V under input voltage. Specifications: Output...

This will flash a LED, employing a single 1.5v cell. it's going to even flash a white LED even supposing this kind of LED needs regarding three.2v to 3.6v for operation. The circuit takes regarding 2mA however produces a really bright flash. LED on 1.5v SUPPLY A red LED needs regarding one.7v before it'll begin to illuminate - below this voltage - NOTHING! This circuit takes regarding 12mA to illuminate a red LED employing a single cell, however the fascinating feature is that the approach the LED is illuminated. The 1u electrolytic may be thought of to be a 1v cell. (If you wish to be technical: it charges to regarding one.5v -0.2v loss as a result of collector-emitter = one.3v and a lost of about 0.2v via collector-emitter in diagram B.) It is firstly charged by the 100R resistor and therefore the third transistor (when it's totally turned ON via the 1k base resistor). this is often shown in diagram "A." throughout this time the second transistor isn't turne...

Skema Rangkaian Circuit combination of the 3 IC TDA2822  above can be used for 5.1 audio power amplifier system with low power output . The input signal used is analog signal not digital (SPDIF) , so it needed some input to the jack input. The speakers are suitable for use have impedance 8 Ohms , and with power 4 Watt, to Left , Right , Rear pair , center , and subwoofer speakers. To run this circuit , is also required circuit for volume control as tone control.

1.5V POWERED LED FLASHER ELECTRONIC DIAGRAM It is a charge pump design. This is where a capacitor (electrolytic) is allowed to charge and is then raised higher and allowed to discharge into a load. The load sees a voltage that can be higher than the supply.

Each one of the devices must counter the amateur electronics store , an adjustable voltage direct current power source. I gave the circuit diagram below 1 volt and 40 -volt power supply, the output can be adjusted arasınada as miliamperle 5 amp maximum current is adjustable from 50 . 1-40 V, 50 mA - 5A Regulated Power Supply Circuit Diagram  In this way could be used for voltage source can also be used as a constant current source . Adjustable current limiting , since it is clear that the short-circuit protected . In this phase, on my testing of other circuits , and calibrations can be used successfully in conjunction with a digital voltmeter . Circuit held four transistors . Network isolation transformer , 220V primary and secondary of the power of 35 to 40 volts and 100 VA transformer should be .

  This 12V or 24V high-current DC Motor Speed Controller is rated at up to 40A (continuous) and is suitable for heavy-duty motor applications. All control tasks are monitored by a microcontroller and as a result, the list of features is extensive. This high-current motor speed controller is based on a PiC16F88 microcontroller. This micro provides all the fancy features, such as battery monitoring, soft-start and speed regulation. it also monitors the speed setting potentiometer and drives a 4-digit display board, which includes two pushbuttons. The 4-digit display board is optional, but we strongly recommend that you build it, even if you only use it for the initial set-up. it unlocks the full features of the speed controller and allows all settings to be adjusted. The microcontroller will detect whether the display board is connected, and if not, the speed controller will support only the basic functions. in this simple mode, it will function as a simple speed-regulated con...
