Have you ever been in class or at work and keep falling asleep? Well no need to worry now as I am striving to create a machine that lightly pokes you every couple minutes so that you will never doze of again. I am using 3D printing and i am also using the air around use as a power source to power my machine. Utilizing 3D printing has affected my understanding of how technology can change the world as you can create anything with it. 3D printing can make something super small, but can also make a house if you give it enough time.
