Build a Long Line Ir Drop Voltage Recovery Circuit Diagram

How to Build a Long Line Ir Drop Voltage Recovery Circuit Diagram? This Simple Long Line Ir Drop Voltage Recovery Circuit Diagram provides a unique solution to a common system-level power distribution problem: When the supply voltage to a remote board must traverse a long cable, the voltage at the end of the line sometimes drops to unacceptable levels. 

This + 5-V/ + 5-V converter addresses this by taking the reduced voltage at the end of the supply line and boosting it back to + 5 V. This can be especially useful in remote display devices, such as some point-of-sale (POS) terminals, where several meters of cable could separate the terminal from the readout.

1KHz IR transmitter circuit

The circuit is based on a NE555 timer
IC (IC1) which is wires as an astable multivibrator to produce 1KHz
pulses. The output pulses of the IC1 will be amplified by the Q1(SK100)
to drive the two IR transmitter LEDs wired serially. The resistors R1,
R2 and capacitor C2 determines the operating frequency of the IC.The
circuit starts emitting IR pulses when ever the push button switch S1
is pressed.

Circuit diagram with Parts list.

Notes.

• The circuit can be powered from a 9V PP3 battery.
• The switch S1 is a push button type switch.
• The IC 1 must be mounted on a holder.
• Basic Oscillator (Tone Generator) At 1.8 KHz -alarm circuits
