How Many do You Know About LM386?
LM386 is a power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200.
The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, making the LM386 ideal for battery operation.

Electronic Components Prices in 2011—Rise or Not?
Because of the increasing costs of labor and raw materials, it is expected that some electronic components will rise in their prices in some degrees. Based on the market survey, inductors and electrolytic capacitors belong to these electronic components as well.
Actually, manufacturers do not insist that the prices of all electronic components will go up in 2011, for example, OVP parts. Lots of manufacturers believe that the price of OVP parts will be stable and will not rise obviously in this year. By contrast, as for aluminum electrolytic capacitors market, some experts of IC components industry, for example, Liu Quanwang, aluminum electrolytic capacitors product marketing director of TDK-EPC group member, Greater China EPCOS, suggest that the price of aluminum electrolytic capacitors would develop in the rising trend. The reason for this phenomenon of electronic components market is the rising cost of some raw materials and energy costs. Moreover, it needs to point out that the raw materials above refer to aluminum and papers and so on; while, energy costs consist of the main production costs of anodic aluminum foil.
At the same time, the costs of labor in China rise rapidly as well and some specialists predict the increasing trend of the cost of Chinese labor will continue in the coming years. What’s more, tantalum electrolytic capacitors’ situation is similar to aluminum electrolytic capacitors’ which has been introduced above. According to the above analysis, some but not all electronic components will rise in their prices in 2011.

Pin Configuration of NE555
Pin 1 (GND) – ground, usually connected to the circuit common ground.
Pin 2 (Trigger) – This pin is the trigger to start it NE555 period of time. Trigger signal on the edge of the voltage must be greater than 2 / 3 VCC, the lower edge shall be less than 1 / 3 VCC.
Pin 3 (output) – When the time period began 555 output the output pins to move less than the supply voltage of 1.7 volts of high potential. End of a cycle back to O volts output of the low potential. High potential around the time of maximum output current of 200 mA.
Pin 4 (Reset) – sent to a low logic potential of this pin will reset the timer and when the output back to a low potential. It is often not receiving the positive supply or ignored.
Pin 5 (Control Voltage) – to allow the pin voltage changes by external trigger and gate threshold voltage. When the timer is operating in a stable or oscillating mode of operation, this input can be used to change or adjust the output frequency.
Pin 6 ( Threshold) – Pin 6 output was low and to reset the lock state. When the pin voltage from 1 / 3 VCC voltage of the following go to 2 / 3 VCC above start this action.
Pin 7 (Discharge) – The main output pins and pin have the same current output capacity, when the output is ON when LOW, a low impedance to ground, when the output is OFF HIGH, high impedance to ground.
Pin 8 (Vcc) – This is a 555 timer IC’s positive power supply voltage.
