Electrical Mini Project Ideas for Engineering Students Electrical engineering is one of the main branches in engineering which deals with electronics and electricity. The main job of an electrical engineer is to make the distribution of energy to the devices using his knowledge and to solve the technical problems. For that purpose, engineering students have to get a good knowledge of electrical concepts by doing some electrical projects in the final year itself. So, it is very important to concentrate on some electrical mini project ideas to get succeed in engineering. And also, to teach students about the concepts & theories of electric engineering, it is not necessary to formulate complex circuits, but just practice some simple electrical projects. Electrical Mini Project Ideas for Engineering Students Have a look at some electrical project topics for engineering students. Electrical Project Ideas Design of PM Generator for A Vertical Axis Wind Turbine The aim of this project is to design a generator of 20 kW for a vertical axis wind turbine with a wind speed of 10 m/s. This generator has only a few moving parts which not only make it tougher but also reduce its cost of maintenance. However, the turbine takes upwind from every direction but its rotation speed ratio is lower than horizontal axis wind turbines. Owing to the size of the generator it could be inferred that it would be expensive as the Neodymium magnets used in the generator are costly. After the simulation of various designs a very promising design has been finalized which fulfills all the specifications. The efficiency of this design is above 95% and it provides 20 kW power output. Furthermore, here, the usage of hard magnetic material would be relatively low. This design has a single row of cables per slot which prevents the formation of heat pockets between cable rows. Although two or more cable rows per slot would make a smaller and efficient machine the only flaw with this design is the formation of heat pockets. Chopper Based Speed Controlling of Electric Motor The main concept of this project is to operate the DC motor with separately excited through a chopper based on IGBT. This controlling process can be done by changing the field flux as well as armature voltage. In this project, the motor speed can be obtained below or above the rated speed by altering the armature voltage. This armature voltage can be controlled through a chopper based on IGBT. According to the required speed, this chopper uses the signal from the controller & changeable voltage can be applied to the motor’s armature. The main benefit of this project is that the speed of the motor will change consistently using armature voltage & changes inversely using field voltage by maintaining armature & field voltages stable. As compared with SCR based circuit, IGBT based chopper will give smooth control operation. So, this project is used to chop the frequency and speed control of the DC motor can be achieved. Low-Cost FM Booster In this project, we are showcasing a nonexpensive circuit of an FM booster that can be brought into play to eavesdrop to FM programs from far-flung FM stations and that too clearly. The circuit consists of an ordinary emitter tuned RF preamplifier cabled in the region of VHF or UHF transistor (2SC2570). (Just C2570 is interpreted on the transistor body.) Built-up the circuit on a top-quality PCB (if possible on- glass-epoxy). Fiddle with input or output trimmers for the highest frequency. The input coil comprises of 4 turns of 20SWG enameled with copper cable (to some extent space wound) approx 5mm diameter. It is wrapped at the initial turn from the ground lead end. The input coil is the same as the output coil but contains 3 turns. Pre-study of New Electrical Coupling Between Train Cars This is an initial study to determine the possibility to substitute distinct control signal wires over the electrical coupler between the train cars with a data bus system. Due to the high amount of contacts it contains, the coupler becomes large and heavy and so the manufacturers, who try to upgrade the existing fleet, face difficulty in transferring more signals as the coupler has no spare contacts to use. Apart from the control signals the electrical coupler also has Ethernet and power signals. At times Bus systems are also used by some trains for control signals or/and signals containing large amounts of data. This report presents some common ways that manufacturers use for allocating electrical signals throughout the train. It also contains some design recommendations for a system that would gather existing signals to a bus system. The report also incorporates two design proposals for the above-mentioned system. The study reveals that there are already systems in the market that transfer control signals over a bus but they are more focused on the under-construction trains. This is why a new bus system would only be appropriate for upgrading existing couplers so as to free some space in the electrical coupler unit. Power Management through Energy Harvesting Concept The aim of this project is to accumulate and optimize the usage of power. In general, the control of this project is laid on the temperature and light sensors. Once the components are installed, the process becomes automatic. As the title of the project suggests, in this project we intend to manage and study the power loads in different conditions. It is noticed that if the load at a particular zone is increased then the control will trip. In order to overcome these problems, we have designed a circuit. The aim is to reduce the expenditure of supplied power to the load point. Self-Powered Door Bell Watcher This project aims at facilitating the homeowner to know who rang the bell in his/her absence. This self-powered device intends to allow people to monitor if someone has rung his/her door-be in his/her absence. The installation process of this simple device involves connecting the circuit to the two doorbell coil leads. When the door-bell is rung, an ac voltage of about 10-16 V is created at its ends and hence is rectified by Diode and charges Electrolytic Capacitor. Though this device was initially proposed to be used when a person leaves the house for a couple of hours tests have shown that even if cheap capacitors are used, this device guarantees a minimum 15 days of memory. Flashing Beacon This project of flashing beacon has several usages. It can be utilized as a de-anxiety sign-on freeway or as a track director for parking spaces, malls, hospitals, hotels, etc. In this project, we present a flashing beacon that brings into play a renowned controller IC LM317T. The LM317T control device can supply over 1 amp. A little 12V, 10W tube-light with a top-quality reflector can be used as an excellent noticeable blinker. A 12 to 15V, 1A DC supply is united to the input point of the IC. A 12V, 10W tube-light, and a blend of capacitors & resistors are fixed amid the output point and ADJ point of the IC. The IC is supplied with an aluminum heat-sink to scatter the warmth produced while supplying full current. As the IC has an integral switch-on current restrictor, it makes longer the life of the tube-light-light. For the given values of capacitors & resistors, the tube-light sparks at approx four cycles/second. The amount of sparks lies in the charge & discharge span of the capacitors. Varied values of capacitors & resistors can be employed to boost or reduce the number of sparks. Low-Cost Hearing Aid Hearing aids available in the market are really very costly. In this project, we are developing an inexpensive hearing aid circuit that brings into play just 4 transistors and little reflexive parts. After turning ON the power button, the condenser microphone senses the noise sign, which is improved by transistors. Later the improved voice sign goes through couple capacitors to the bottom of the third transistor. The voice signal is extra improved by forth PNP transistor to drive a stumpy impedance ear-phone. Forth & fifth capacitors employed are the power supplying decoupling capacitors. This circuit can be effortlessly fixed on a small, generally used PCB or a Vero-board. It functions with a 3V DC supply. For this purpose, two small 1.5V batteries are used. Turning knob ‘OFF’ will deactivate the circuit & to boost the sensitivity of the microphone, place it inside a tube. Anti-Bag-Snatching Alarm In this project, we are developing a simple alarm circuit to stop snatching of your assets during travel. The snatch circuit enclosed in a bag or suitcase alerts you with a loud alarm, activating police siren, in case of snatching your bag or suitcase. This will magnetize the notice of other nearby and the thief can be trapped. While in standby mode, the circuit is locked. When the thief attempts to snatch the bag, the circuit activates the alarm. The circuit is intended around op-amp IC CA3140, which is arranged like a comparator. Stress Meter This stress meter scrutinizes your emotional level. If the stress level is high, it provides a visual signal via LED (light-emitting diode) together with a warning alarm. This is a small gear to be worn around the wrist like a watch. The gear is constructed on the theory that the skin’s resistance differs in accordance with your emotions. If stress is less resistance is offered by the skin, and when the body is relaxed high resistance is offered by the skin. The skin’s low resistance is due to the boost in the supply of blood to the skin. This boosts the skin’s permeability & therefore electric current’s conduction. This is a sensitive circuit & can even sense little variations in mood & emotions. The touchpad detects the variation in the stress meter & sends the same data to the circuit. Light Fence The fundamental trouble with maximum ordinary light sensors is that they necessitate the t arrangement of the light rays to silent the circuit while in standby mode. This project explained here extremely sensitive that it can sense a person passing by few meters away in the daytime or beneath electric lamps with no proper light beam arrangement. It needs practically no setup and can be merely positioned within the line of sight of roughly any source of light comprising sparkling daylight or glowing electric lamp. The alarm alert produced from the circuit is loud enough to identify the access of any unknown person in any protected region under surveillance. The circuit employs a volt comparator and a mono-stable regulator to provide the alert alarm on sensing a person around. An electric engineering student must be keen enough on doing the mini electric projects. Indulge yourself in any of the constructive work or projects this can bring immense variation in the amount of knowledge you have. Electric engineering students endeavoring on a mini project and coming out with colors of success will be like an icing on the cake. You can actually be exceptional once as you initiate obtaining practical acquaintance by doing mini electrical projects. So do not wait for others, place, instructions, or time. Explore the alternatives accessible and investigate.
