Simple LED Flasher Circuit Using 555 IC
This is a simple LED flasher project that built uses a common 555 timer IC for its operation. It is configured as an unstable mode which means that its output is a square wave oscillator. Two LEDs are connected to its output in such a way that when one LED is ON, the other LED will turn OFF. It circuit uses only 10 simple parts that are easily available at any electronic shops. This is the simple figure of the circuit;

Principle work of this circuit is capacitor C2 charges exponentially through resistors R1, R2 and the resistance of the variable resistor. When C2 has charged to about 2/3 VCC it stops charging and it discharges to about 1/3 VCC through R2 and the VR resistance via pin 7. This is the standard operation of a 555 timer. When a Vcc of 5 V to 15 V DC is applied to the circuit, the LED will start to flash. The frequency of the flashing can be changed by varying the resistance of the potentiometer.

One IC two tones Siren
This schema is intended for children fun, and can be installed on bicycles, battery powered cars and motorcycles, but also on models and various games and toys.
With SW1 positioned as shown in the schema diagram, the typical dual-tone sound of Police or Fire-brigade cars is generated, by the oscillation of IC1A and IC1B gates. With SW1 set to the other position, the old siren sound increasing in frequency and then slowly decreasing is reproduced, by pushing on P1 that starts oscillation in IC1C and IC1D.
The loudspeaker, driven by Q1, should be of reasonable dimensions and well encased, in order to obtain a more realistic and louder output. Tone and period of the sound oscillations can be varied by changing the values of C1, C2, C5, C6 and/or associated resistors. No power switch is required: leave SW1 in the low position (old-type siren) and the schema consumption will be negligible.

R1,R3___470K 1/4W Resistors
R2______680K 1/4W Resistor

2x40W Two Channel Class AB Audio Power Amplifier IC
Overview
The STK402-000 series products are audio power amplifier hybrid ICs that consist of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYOs unique insulated metal substrate technology (IMST). SANYO has adopted a new low thermal resistance substrate in these products to reduce the package size by about 60% as compared to the earlier SANYO STK407-000 series.
