Summary

FM booster is a low-cost circuit that can be fed between an FM receiver and antenna to listen to distant commercial FM stations clearly.The main components of the circuit comprise of CS2570 transistor, trimmers and inductor coils.

Learning

Things which you can learn:
*Application of C2570 transistor.
*Working of trimmers.
*Maximum Power Transmission
*RF pre amplifier setup.

Product Description

The FM booster can be used to listen to programs from distant FM stations clearly It basically extends the range by which distant channels can be received.

Working

The circuit comprises a common-emitter tuned RF preamplifier wired around VHF/UHF transistor 2SC2570.

The input/output trimmers (VC1/VC2) for a set for maximum gain. An input coil L1 consisting of four turns of 20SWG enameled copper wire (slightly space wound) over 5mm diameter former, is tapped at the first turn from the ground lead side. Coil L2 is similar to L1 but has only three turns.

Product Description

A stepper motor is an electromechanical device, which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The motor's rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied.

We can use the stepper motor to control the motion of a robot but the biggest hurdle is the wired controller. We can control the stepper motor wirelessly through RF link. In this project, we are controlling the stepper motor wirelessly through RF link. We are using RF module and an AT89S52 microcontroller to achieve this motive.

Rs. 4,000.00

Product Description

The Project Long Range Remote Control can be used to remotely control a number of Electrical or Electronic Gadgets connected to it. Unlike Infra Red remote control, this Project employs FM Transmission and Reception, and hence it can be used for comparatively a longer range.

Any gadget can be switched on/off by keying the number allocated to it. The Receiver is made up of the famous 8-bit Microcontroller from Atmel. The Microcontroller is used as the Master in the receiver end which is used to control all the devices. It decodes the Signal from the transmitter and controls the relays according to the signal. For transmission, we are using frequency modulation at the frequency of 433.92Mhz.

Save Rs. 301.00
Rs. 3,300.00
Rs. 2,999.00

Summary

The Remote-Controlled Land Rover is a vehicular model that can be controlled remotely using RF. The Land Rover can be remotely instructed to perform simple functions through appropriate push-button switches on the remote, like: -forward -backward -right -left The Remote-Controlled Land Rover is capable of stopping automatically on encountering a physical obstruction while moving in forward and reverse directions. Build this kit and enter into the world of RF controlled devices! No. of ICs used: 5

Learning

Things which you can learn:

*Learn application of encoder and decoder ICs HT12E and HT12D.
*Learn the designing of RF transmitter and receiver.
*Concepts of DC Geared Motor.

 

Product Description

The Remote Controlled Land Rover operates using RF transmission. The remote control has the advantage of adequate range (up to 200 meters with proper antennae) besides being omnidirectional. The Land Rover can move in forward, reverse, left and right directions. The decoder being used for the project has latched outputs and as such the buttons on remote control need not be pressed for more than a few milliseconds.

Working

Forward and reverse movement: The Remote-Controlled Land Rover uses a 30-rpm geared 6V DC motor coupled to the left front wheel and another identical motor coupled to the right front wheel. During forward (or reverse) movement of the vehicle, the two wheel shafts move in opposite directions (one clockwise and the other anticlockwise). Steering control: There are different methods available for steering a vehicle. For the Lan Rover steering, the two driving wheels are independently controlled to turn. For the rear wheels, a single 5cm diameter plastic caster wheel is being used. A Caster wheel turns by 180° when the direction of the vehicle motion is reversed.

This way the movement of the rover becomes stable in both the forward and reverse directions. The steering (clockwise or anticlockwise) motion is achieved by driving only one wheel at a time. Drive Circuit: The input terminals of the motor drive circuit for the right-hand motor have to be fed with reverse-polarity control signals compared to those of the left-hand motor drive circuit. Remote Control. For remote control, the Holtek encoder-decoder pair of HT12E and HT12D employing RF as well as IR principles, are used. Both of these are 18-pin DIP ICs.
