The basic techniques of designing electro-mechanical systems and to gain the knowledge on tuning and controlling dynamic systems. The design of this course should attract special interests of many universities becauseit actually requires students to build the most expensive part of the instruments so that the instrumentation budget would fit in a reasonable amount of money. These instruments include

a simple PC based spectrum analyzer, a motor driver and motor speed/position controllers. Experiments use these instruments include design of analog circuits, design of power electronic circuits and motor drives, identification of dynamic systems, and speed/position control of servo motors. All experiments are specially designed for mechanical engineering students to gain basic electrical engineering techniques, control experiences, and dynamic system instincts. The responses from the students who took this course are overwhelming. Also many industrial companies found very useful to employ students who has taken this course. Mechanical engineers these days are different from the past. They need more knowledge in the field of Electrical Engineering and Computer Science. The work they need to do also covers electronics, programming, electric machinery, and signal processing. A course designed specifically on integrating these fields becomes very important to mechanical engineering students. We strongly feel that a laboratory that covers these fields should be designed. Design experiments to build the course required instruments. Students in the process of building these instruments can learn the basics of analog/digital circuits, power electronic circuits, and signal processing. Consider a standard block diagram of motor control system in figure 1. In order to perform this experiment, we need to teach students how to design...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
