Great work, Keep it up.. Even Electronics engineering graduates like me was not able to make such things in our final project, today college syllabus is full of theory only and that syllabus itself teaching technologies 50 years back, From where you are coming how you learned all these things, anyway great and my advice is if you are planning to join for b tech dont join in ordinary engineering colleges in kerala. Join colleges like Amrita University or something like that, so you get enough exposure and high tech labs in their colleges to experiment with robotics and electronics and also great support from teachers otherwise you will end up mugging tons of books of useless proofs, derivations and a useless old laboratory where not even an ammeter works properly.So choose your college well when you join for B Tech.Anyway Best wishes and great website.
