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:
- Modulation: Build a circuit for modulation using IC MCI496/8038 on general purpose PCB and prepare the report.
- FM transmitter: Build a circuit on general purpose PCB for FM transmitter using IC 8038/ transistor BF549 and prepare a report.
- FM transmitter: Build a circuit on general purpose PCB for FM transmitter using IC NE555 timer IC to produce audio tone and use JFET to built harltley oscillator and prepare a report
- Mobile jammer: Build a circuit on general purpose PCB for mobile jammer.
- Tuning of IFT: Build a circuit on general purpose PCB for tuning 1FT at 455KHz.
- FM encoder / decoder circuit :- Establishe the communication with high level security using RF600E and RF600D ICs this pair of encoder and decoder ICs.The operating voltage of these ICs is from 2V to 6 6V DC and prepare a report.
