Low cost EEE projects

“Engineering stimulates the mind. Kids get bored easily. They have got to get out and get their hands dirty: make things, dismantle things, fix things. When the school can offer that, you’ll have an engineer for life.”
—Bruce Dickinson

The thinking of an Engineer needs to be creative and he must be imaginative as much as possible. He must be ready to explore things which fascinate things and rebuild them. This knowledge and experience of rebuilding things are a part of projects which engineers do in their life.

Engineers are always in search of projects, and finding meaningful projects makes that search worthwhile. Listed below are some electrical engineering project ideas for such engineers. These works may use high voltage working, remember safety first.

These hand picked Electrical and Electronics Engineering projects are simple as well as interesting.

  • 1 kW Sine Wave Inverter

    1kW Sine Wave Inverter

    An inverter provides power backup for mains-based appliances in the event of a power failure. Most of the inverters available in the market have complicated circuit design and are not very economical. Some of them produce a square-wave output, which is undesirable for inductive loads. This project presents a simple inverter circuit that produces 50Hz quasi sine-wave output using a single IC CD4047 and some discrete components making it a very cost-effective solution.

  • Infrared Motion Sensing Relay Switch

    Infrared motion sensing relay switch

    This project is designed for use with all kinds of medium-power automobile/domestic 12V DC loads. The standard passive infrared (PIR) motion sensor module controls this type of solid-state relay (SSR) switch. A PIR sensor is an electronic device that can measure IR light radiating from objects in its field-of-view. Apparent motion is detected when an IR source with one temperature (such as a human being) passes in front of an IR source with another temperature (such as a wall). The PIR sensor module, centred on a PIR sensor, has elements made of crystalline material that generates an electric charge when exposed to IR radiation.

  • Low-Cost Dusk-Dawn controller

    Low cost dusk dawn controller

    This dusk-dawn controller is built around a light-dependent resistor among other components. The common battery supplies the circuit for load. Resistors work as voltage divider and current limiter in the circuit. LEDs indicates the circuit deactivation. An n-channel MOSFET switches the action of an LED light.

  • Dual Axis Solar Tracker System

    Dual axis solar tracking system

    This system requires involvement of a wide range of engineering including mechanical electrical and electronics. The mechanical part would involve designing a smooth gear system to move as per requirement. The electrical part would be the working of solar panel and battery requirement. The electronics would involve designing the sensor system that would generate commands for the gear system to act accordingly. The system employs spur gear for the implementation of the dual axis solar tracker. Atmel IC AT89C51 implements this system.

  • Plus-Minus 5V supply from 9V Battery

    Plus-Minus 5V supply from 9V Battery

    Op-amps require dual-polarity supply for proper operation. When working with battery supply, it becomes difficult to get dual power supply for the op-amps. Presented here is a simple circuit that provides ±5V from a 9V battery. This is one of the interesting projects among Electrical Engineering Project Ideas. Op-amps require dual-polarity supply for proper operation. When working with battery supply, it becomes difficult to get dual power supply for the op-amps.

  • Configuration RS232 to TTL to I2C adapter

    Configuration RS232 to TTL to I2C adapter

    RS232 signals cover a much longer distance than standard TTL and I2C signals. These signals have better noise immunity as well. RS232 is a well-known standard supported by many popular ICs and therefore is still widely used. Sometimes we want to send TTL and I2C signals over a longer distance. This project describes how these signals can be extended through RS232 lines.

  • Design and analysis of single stage Amplifier using C++

    Design and analysis of single stage Amplifier using C++

    Many formulae are required to calculate the parameters involved in a circuit of a transistor based audio amplifier. Some of these values involve resistors, coupling capacitor, bypass capacitor, power consumption, current flowing through different components. Even a regular calculator takes significant amount of time to calculate such parameters. C++ program can calculate all the parameters in the fraction of a second. This project presents a single-stage transistor audio amplifier that requires a total of 19 formulae to obtain the values of components and analyse the circuit.

  • Programmable Three Phase controller for ON/OFF Motor

    Programmable Three Phase controller for ON/OFF Motor

    A programmable time switch is useful in designing an automatic on/off controller for 3 phase electric motor. This next project proposes a system with two programmable time switches for setting the starting and stopping times of the motor. Two control circuits interface with the start/stop switches of the 3-phase motor starter. There is provision for setting days of the week for the controller to function as well.

  • High Power LED stroboscope

    High Power LED stroboscope

    Stroboscope is a convenient and accurate enough instrument to measure speeds of rotating objects in homes or industries. One can use it to find the speed of fans, motors or any other rotating object. It is a flashing light that provides sharp light pulses at a variable rate. An object rotating with frequency matching the pulsed light is observed as stationary.

  • Password based circuit breaker

    Password based circuit breaker

    A circuit breaker protects electrical circuits from damage n case of overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. The system uses an 8 bit microcontroller of 16f877A family. An EEPROM stores the password and is easily changeable. The password is entered through a keypad and a relay opens or closes the circuit breaker, which is indicated by a lamp.
