Life at MIT can be tough. With all the problem sets, and projects taking up time, when I come back to my dorm room to crash, I donâ€™t want to waste time opening doors myself! Thatâ€™s why my room is outfitted with an iPhone controlled hydraulic door opener and unlocker. Just tap the â€œiDoorâ€ app on my phoneâ€™s home screen, and the door opens for me. Its 2009 after all, about time we stopped carrying around shaped bits of metal to open up locked doors.
