About Actual-Virtual Machines (AVMC) Lab
▼
The idea of Actual-Virtual Machines (AVMC) Lab was born during Corona pandemic when students were trapped at their homes and as a teacher we were supposed to "run the show" through online lectures. The subject like machines without lab practical is like teaching swimming theoretically through books and lectures and asking the person to get down in ocean without any formal training of practical swimming.
Hence, to give the "feel of Electrical Engineering" and understand the actual operation of machines, this attempt was made to make Machines demo available even at home starting from basic core Electrical Engineering of Diploma level to UG to PG to even PhD, advancing a page-by-page (some pages are still in progress). Hence, during corona (2020-21), with whatever limited technology we had, and with the permission of then HoD, Prof. F. S. Kazi, our Electrical Engineering Department (EED) non-teaching staff (especially, Mr. Mayekar) started recording the experiments. Initial attempts were recoding through our normal mobile phones so the voice quality and sometimes even visibility was not actually very good. However, that was taken care by providing the recorded lectures for that particular experiment. Our present Director, Prof. Sachin Kore provided a valuable suggestion of adding voice over such lab videos which we will implement soon. However, it is only through the encouragement of Director Sir, now we are sharing this website officially through VJTI platform for students, which otherwise I was doing personally though Google Classroom. I believe this should be available to all VJTI students through their VJTI email ID and soon we will make it open for all.
In contrast with most of the virtual labs which are of drag-drop-connect-click-run type or demo type, this AVMC is ACTUALLY showing how to start a experiment, how to make connections, how to switch-on, how to take readings, how to switch-off in EED, Machines Lab where students would actually do everything themselves under the supervision of subject teachers, and hence, the name is "Actual-Virtual" Machines Lab.
Though, we are going to record some of the experiments again, the website is made available in its "present-form" so that ongoing students should also get the benefit of the content.
A mention of all those students who helped in various forms in these years to develop the content for AVMC is available on the page of Team, History and Story. Even a copy of the very first version of Machines Lab Manual developed from 2006-2009 is available on the page, "Machines Lab Manual 2006 Version".
The purpose of making this AVMC available for the students (in its "raw form" at present) is purely academic and in the view of student benefit so all your healthy criticism and suggestions are most welcome.
