proposal
We are want to design a beverage coaster that has the ability to detect when drinks are low and capture data on drinking habits. We believe our project will be useful for restaurant workers because they will be able to spot near empty glasses more easily (especially in a dark environment), and they will be able to track how much of each beverage is usually consumed by customers.

Our enhanced beverage coaster will detect the amount of beverage left in the glass by using a pressure/weight sensor and will light up an LED to a certain color to make it easier to restaurant workers to spot near empty glasses. Also, we will be tracking the amount of beverage consumed by the customer using the pressure/weight sensor. Our coaster will also have a wireless chip that will relay data to a central location (probably a phone or computer for this prototype). We plan on probably using a coin cell battery to power out project.

We believe this project is challenging because it needs to be not too expensive, low power, and have the ability to transfer data wirelessly. Also, detecting the decrease in the amount of beverage in a glass can be tricky due to the glass being picked up in uncertain intervals by the customer.

Baseline:
-Pressure sensor working
-Able to detect a near empty glass
-Replay amount of beverage drunk by customer somewhere (probably phone)

The Dream:
-All of the above working
-Have a central module to transfer information to
-Able to select type of beverage before serving customer

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!
