Suggested Micro-Projects
Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project are group-based. However, in the fifth and sixth semesters, it should be preferably be individually undertaken to build up the skill and confidence in every student to become problem solver so that s/he contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three.
The micro-project could be industry application based, internet-based, workshopbased, laboratory-based or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs. UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry oriented COs.
A suggestive list of micro-projects are given here. Similar micro-projects could be added by the concerned faculty:
- Prepare an eletronic device board with specifications of each.
- Build and Testan audio amplifier circuit.
- Build automatic darkness detector circuit using LDR sensor and BJT as a switch
- Build a basic remote tester using transistor and IR sensor.
- Design and build dual voltage regulator for different voltage range.
- Build a simple touch switch/ touch alarm /rain alarm sensor.For the micro-project undertaken, the student should also simulate and develop the PCB layout in any open source software like evaluation versionof Multisim, Microcap, and Proteus etc. during building and testing of the circuit. This will also help him/her to develop competence in using CAD tools.
