Our group designed and built a stereo network that streams audio from a Bluetooth-enabled device and automatically handles playback from the speakers closest to the user. The system is comprised of a hub, to which the user's device connects to, and speaker adapters, which enable any speaker with a 3.5mm audio jack to interface wirelessly to our hub. Each unit consists of a Bluetooth chip and a microcontroller. The hub broadcasts audio to the speaker adapter, which is constantly sending back signal strength data about the user's audio device. Each of our components is powered by a lithium-ion battery and charged over USB. With our Bluetooth stereo network, a user can enjoy his/her music uninterrupted from the living room to the bedroom without having to worry about connecting or muting any speakers.

Our project is to be a reliable, robust, and intelligent irrigation controller for use in areas where reliable weather prediction, water supply, and power supply are not found.

Upon completion of the project, our device will be able to determine the moisture level of the soil, the water level in a water tank, and the temperature, humidity, insolation, and barometric pressure of the environment. It will perform some processing on the observed environmental factors to determine if rain can be expected soon, Comparing this knowledge to the dampness of the soil and the amount of water in reserves will either trigger a command to begin irrigation or maintain a command to not irrigate the fields. This device will allow farmers to make much more efficient use of precious water and also avoid dehydrating crops to death.

In developing nations, power is also of concern because it is not as readily available as power here in the United States. For that reason, our device will incorporate several amp-hours of energy storage in the form of rechargeable, maintenance-free, lead acid batteries. These batteries will charge while power is available from the grid and discharge when power is no longer available. This will allow for uninterrupted control of irrigation. When power is available from the grid, our device will be powered by the grid. At other times, the batteries will supply the required power.

The project is titled S.I.P. because it will reduce water wasted and will be very power efficient (by extremely conservative estimates, able to run for 70 hours without input from the grid), thus sipping on both power and water.

We welcome all questions and comments regarding our project in its current form.

Thank you all very much for you time and consideration!
