This project is available at Brushless DC Motor Driver
8) HVDC Power Supply Design
Circuits like Geiger counters, insect zappers, Nixie tubes, and sensors require high-voltage direct-current (HVDC) supplies. There are various types of HVDC supplies available in the market, including voltage doublers or quadruple, flyback converters, and boost converters.
Some of these have low current-output capacity. But with the right calculations using basic boost conversion formulae, we may achieve HVDC supplies capable of clean and high current capacity. Presented here is a boost converter design using an MC34063 DC-DC converter.
This project is available at HVDC Power Supply Design
9) Micro Inverter
A simple low-power inverter circuit is described here, which converts 12V DC into 230V AC. It can be used to power very light loads like night lamps and cordless telephones but can be modified into a powerful inverter by adding more MOSFETs.
This project is available at Micro Inverter
10) Automatic Anchor Light
Federal and international regulations require boats to carry lights during sunset, sunrise, and in conditions with restricted visibility. The number and colors of light vary with the size of the vessel. A masthead anchor light is out of fashion as it is too high above the water level. This makes it difficult to judge the position of the boat, especially in a pitch-dark anchorage.
This project is a compact yet inexpensive automatic anchor light integrated with an ambient light sensor that turns it on and off automatically.
This project is available at Automatic Anchor light
11) High-Impedance Audio Buffer With JFET
The buffer circuit described here is useful in enhancing the AC input impedance of audio amplifiers used with pickups in musical instruments. Signal sources for amplifiers and passive pickups for electric guitars require very high impedance of over 5-mega-ohm. This can be achieved easily with a junction field-effect transistor (JFET) but may require a special design of the printed circuit board (PCB), appropriate construction techniques of the box, and proper cables and connectors.
This project provides a solution for a high-impedance, low-cost, low-quiescent current, buffer-follower based on PN4393 JFET.
This project is available at High-Impedance Audio Buffer With JFET
12) PIN Diode-Based Fire Sensor
This is an ultra-sensitive fire sensor that activates an alarm when it detects fire. In this circuit, a sensitive PIN diode is used as a fire sensor for longer-range fire detection. It detects visible light and infrared (IR) in the range of 430 nm – 1100 nm.
Visible light and IR from the fire activate the sensor to trigger the alarm. It also detects sparks in the mains wiring and if these persist, it gives a warning alarm. The anode can easily be identified from the top-view flat surface of the photodiode. A small solder point to which a thin wire is connected is the anode and the other one is the cathode terminal.
This project is available at PIN Diode-Based Fire Sensor
13) Plus-Minus 5V Supply From 9V Battery
Op-amps require a dual-polarity supply for proper operation. When working with a battery supply, it becomes difficult to get a 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 most interesting projects among Electrical Engineering Project Ideas. Op-amps require a dual-polarity supply for proper operation. When working with a battery supply, it becomes difficult to get a dual power supply for the op-amps.
This project is available at Plus-minus 5V Supply From 9V Battery
14) Infrared Motion-Sensing Relay Switch
This project is designed for use with all kinds of medium-power automobile/domestic 12V DC loads. It is a simple solid-state relay (SSR) switch, controlled by a standard passive infrared (PIR) motion sensor module.
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, centered on a PIR sensor, has elements made of crystalline material that generates an electric charge when exposed to IR radiation.
This project is available at Infrared Motion-Sensing Relay Switch
15) Low-cost LPG Leakage Detector
The circuit for an LPG leakage detector is readily available in the market, but it is extremely expensive and usually based on a microcontroller (MCU). This project presents a low-cost LPG detector that you can build a circuit easily.
The main objective of the circuit is to detect LPG leakage anywhere. At the heart of the circuit is dual comparator IC LM393 (IC2). It is used to compare two different voltages, in this case, reference voltage and MQ-6 gas sensor output voltage.
This project is available at Low-Cost LPG Leakage Detector
16) Low-Cost Dusk-Dawn Controller
This dusk-dawn controller is built around a light-dependent resistor among other components. The common battery supply is used for operating the circuit as well as for load, that is, for power LED/small inverter circuits. Resistors work as voltage dividers and current limiters in the circuit. LEDs are used as circuit deactivation indicators. An n-channel MOSFET is used for the switching action of an LED light.
This project is available at Low-Cost Dusk-Dawn Controller

Here we present a simple, useful, and low-cost signal generator built around NE555 timers. Using external switches, you can control or select frequency ranges as per your requirements.
This project is available at Signal Generator and Inverter Using NE555 Timers
19) Configurable 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.
This project is available at Configurable RS232 to TTL to I2C adapter
20) Vibration Activated Smart CRO Probe
This is a simple, low-cost, energy-saving, and device-saving circuit for an electronics lab, service center, electronics workshop, or wherever a CRO is in use. Generally, in a repair station, a CRO is used for a very short time. But in most cases, the user fails to switch off the CRO immediately after use.
The service engineer mostly concentrates on faults rather than noticing whether the CRO is on or off. A vibration sensor turns the CRO off when the probe is idle for a specified amount of time.
This project is available at the Vibration Activated smart CRO probe
21) 4 Channel Multi-mode Audio Amplifier
Sometimes we need configurable multichannel amplifiers for experiments or for use in offices or schools. Here is a project based on TDA1554Q, configured for multi-mode functions with four-channel outputs. It has four channels and each channel can provide around 11W over a load of 2 ohms and around 6W over a load of 4 ohms.
The circuit will also work with loads of 4 ohms to 16 ohms. The gain of each channel is fixed at 20dB in single-channel mode and 26dB in BTL mode.
This project is available at 4 channel multi-mode Audio amplifier
22) 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, and the current flowing through different components. A good amount of time is required to calculate such parameters even with a regular calculator. Using a C++ program, all the parameters can be calculated in a 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 analyze the circuit.
This project is available at Design and Analysis of Single-stage Amplifier using C++
23) Four-channel Video and Audio Sequencer

This project is available at a Four-channel video and audio Sequencer
24) Automated USB-controlled Power Switch
Power for TV and set-top box (STB) is derived from a common switchboard. The switched-mode power supply (SMPS) of the TV continues to draw a small amount of power from the mains and the STB is not switched off when you switch off the remote. This next project presents a circuit that can control the main power of an LED TV and the DTH STB. It also protects the devices from harmful initial surges when the power comes back after a power failure.
This project is available at Automated USB-controlled Power Switch
25) 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 designs 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.
This project is available at 1kW sine wave Inverter
26) Four Frequency Generator

These sources are also useful for fast checking of oscilloscopes, probes, multimeters, frequency meters, and other measurement equipment. This project proposes a circuit that produces fixed frequencies of 4MHz, 6MHz, and 10MHz and adjustable square-wave with variable frequencies from around 10Hz to more than 100kHz.
This project is available at 4 Frequency Generator
27) Programmable 3-Phase Controller
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 a provision for setting days of the week for the controller to function as well.
This project is available at Programmable 3 phase Controller for ON/OFF motor
28) High Power LED Stroboscope
A stroboscope is a convenient and accurate enough instrument to measure the 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 a frequency matching the pulsed light is observed as stationary.
This project is available at High Power LED Stroboscope
29) 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 the 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.
This project is available at Password based circuit breaker
