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 :

The circuit of the running light comprises two integrated circuits (ICs), a resistor, a capacitor and seven light-emitting diodes (LEDs), Decade scaler IC2 ensures that the LEDs light sequentially. The rate at which this happens is determined by the clock at pin 14. The clock is generated by IC1, which is arranged as an astable multivibrator. Its frequency is determined by R1-C1. 6-Channel Running Light Circuit Diagram The touch switch, consisting of two small metal disks is optional. When switch S1 is in position ‘off’, the circuit may be actuated by the touch switch. By the way, this enables the circuit to be used as an electronic die (in which case the LEDs have to be numbered from 1 to 6). The running light is powered by a 9 V battery or mains adapter. It draws a current not exceeding 20 mA. Author: L. v/d Heeden Copyright: Elektor Electronics 1998

A very simple 6 channel low cost led driver electronic circuit project can be designed using the MCP34845 LED drivers manufactured by Free scale Semiconductor.The MCP34845 LED drivers operates from 5 to 21 volts and is specially designed for use in back lighting LCD displays from 10" to 17"+ for devices like : PC Notebooks , Net books , Picture Frames , Portable DVD Players , Small Screen Televisions , Industrial Displays , Medical Displays , etc. 6 Channel LED Driver Circuit Diagram The MCP34845 LED drivers is capable of driving up to 16 LEDs in series in 6 separate strings.PWM dimming is performed by applying a PWM input signal to the PWM pin which modulates the LED channels directly.Main features of this driver circuit project are : input voltage of 5.0 to 21 V , boost output voltage up to 60 V, 2.0 A integrated boost FET , fixed boost frequency - 600 kHz or 1.2 MHz , OTP, OCP, UVLO fault detection , LED short/open protection , programmable LED current between 3.0 mA and 3...

iPhone 6 concept shows thinner handset with touch-sensitive home button and 12MP camera Created by Arthur Reis, a budding designer who aspires to join the ranks of Jony Ive and Shin Nishibori someday, 3D renderings of the iPhone 6 imagine a handset that looks largely identical to iPhone 5 (think: anodised aluminium casing with chamfered edges), but an impressive 20 per cent slimmer at just 6.1mm thick. The handset also features a 12-megapixel camera with an ‘iSight Pro’ sensor boasting an f/1.8 aperture and a ‘Magic TrackPad’ that replaces the physical home button with a touch-sensitive equivalent. As far as we’re concerned, this is one of the best iPhone concepts we’ve seen, principally because it doesn’t go crazy on novel or unrealistic features as most concepts do. Apple is always trying to make its handsets slimmer, so a more slender iPhone is within the realms of possibility. And with Samsung upping the ante with a 13-megapixel camera on the freshly launched Galaxy S4, we can cert...
