Adam Wrobel and Michael Grisanti of Cornell University built this device that tracks sound impluses: The core of our system is hardware based analog circuit, which filters, amplifies, and processes the sounds obtained from the microphones. By utilizing hardware for this, we are able to high frequency signal processing without taxing the microcontroller. Also, we remove […]

Time plotting clock
A clock that plots time: The Time Plotting Clock mechanism is fantastically simple, 3 tiny servo motors allow the erasable marker to be moved along the drawing surface and raised when no contact with the surface is desired. This allows the pen to write the time. There is also a tiny eraser located in the […]
