1 Lamp with 2 switches
Series 1 light 2 switch configuration is intended to control lights from two locations arefar apart. Application of series 1 light with 2 switches are often implemented in thehallway or tunnel. In the application in a hallway or tunnel, with a series like this we can turn on or turn off the light from each tunnel or hallway door. The number of lights can bereproduced by paralleling. The circuit is very simple because only built of 1 and 2pieces of fruit lamp selector switch. If you want to use a lamp with a power greater then the switch can be replaced with 1 piece contactor (relay) for each switch. Then switchused to turn on and turn off the relay replacement S1 and S2.
The working principle with 2 series 1 light switch is the light will light when the S1 and S2 different position, and the lights will be on at the time of the switch position S1 and S2 together. In the installation of switches S1 and S2 each put at the end of the hallway or tunnel.

2 Channel MOSFET Car Audio Amplifier
That this amp would not do a good job pushing a subwoofer is that it only has a "Subwoofer level control". This is not to be mistaken for a crossover/low pass filter. You need some form of crossover to keep it from sending high frequencies to the speaker.
Technical Detail for Boss Audio R1002 2-Channel Mosfet Power Amplifier with Remote Subwoofer Level Control :
- 2-Channel MOSFET Power Amplifier
- Remote Subwoofer Level Control Included
- 100W x 2 Max Power
- 100W x 2 RMS Power
- 50W x 2 Max Bridged Power

LM380 Build 2 Watts Audio Amplifier Circuit Diagram
LM380, Build 2 Watts Audio Amplifier Circuit Diagram. Small audio amplifier is useful for audio troubleshooting or simple audio projects. It should be a low cost and easy to build. Using integrated circuit for this purpose is the right choice. With LM380 audio amplifier integrated circuit, 2 Watts power can be delivered. For better thermal endurance, a large copper track can be printed in the board to provide heat sinking, this copper track should be soldered to pins 4, 3, 10, 5, 12 and 11. Here is the schematic diagram of the circuit.

Simple 2 Watt Small Switching Power Supply Wiring diagram Schematic
In this small switching power supply, a Schmitt trigger oscillator is used to drive a switching transistor that supplies current to a small inductor. Energy is stored in the inductor while the transistor is on, and released into the load schema when the transistor switches off.
2 Watt Small Switching Power Supply Circuit Diagram
2 Watt Small Switching Power Supply Circuit Diagram
The output voltage is dependent on the load resistance and is limited by a zener diode that stops the oscillator when the voltage reaches about 14 volts. Higher or lower voltages can be obtained by adjusting the voltage divider that feeds the zener diode. The efficiency is about 80% using a high Q inductor.

Build a 1 2 36V 5A Adjustable Power Supply with LM317
Build a 1.2-36V 5A Adjustable Power Supply schema diagram with LM317. This schema is a simple power supply schema. 1.2 - 36V adjustable bench power supply with 5A of output current. Max input voltage is 37V and output is adjustable via potentiometer between 1.2 up to 36 volts. TIP147 PNP darlington transistor boosts the current of LM317 from 100mA to 5A. LM317 is the most useful and inexpensive adjustable regulator and for this schema you can also use LM317 L that can give 100mA, thats enough for transistor bias.
1.2-36V 5A Adjustable Power Supply Circuit Diagram
D1 and D2 are protection diodes because when you turn the schema off the output capacitors are discharging and can damage the transistor or regulator. 100nf capacitors are in parallel with electrolytic capacitors to remove high frequency noise because large value electrolytic have large ESR and ESL and cant remove high frequency noise.

Head light timer circuit 2
This schema is a compact timer schema that will keep the headlights of your car ON for about 1.5 minutes and then turns it OFF.This schema incorporated to your car will help you to access dark places with out the need to come back and turn OFF the head lights.
When the push button switch P1 is pressed the capacitor C1 is charged to the full battery voltage.As a result the transistor Q1 is turned ON ,which in turns ON Q2 which in turns drives the relay K1 to glow the head lights.The relay K1 will remain activated until the capacitor C1 is fully discharged.The time delay of the schema depends on values of C1 & R1 and here it is set to be 1.5 minutes.
Notes.
* Assemble the schema on a good quality PCB or common board.
* The time delay of the schema can be varied by varying the values of R1&C2.
* At most care must be taken while wiring this schema to your car because a wrong connection could cost you a lot of money.
* The capacitor C1 must be rated at least 15V.
