ya...same here hehehehe... I was working back then on my project "motorless-wireless robot' a lot of criticism that this may not be workable… it was actually a nickel-titanium alloy that everytime it is powered by electricity the wire will be shorten that makes the robot move. My batches spend Php80k - Php150k project. But mine was only about Php3k-5k hahahaha… MCU lang ang nakamahal. Thesis is really fun… you just need to be more resourceful… hardwork & prayers
