31 Enhanced Beverage Coaster

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.

-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

Easy Cube Clock

Featured Project

Today's alarm clock market is full of inexpensive, but hard to use alarm clocks. It is our observation that there is a need for an alarm clock that is easy to set, and turn on and off with little instruction. Imagine an alarm that is set with the intuitive motion of flipping the clock over. When the alarm is on, you can see the alarm time on the top of the clock. To turn off the alarm, you simply flip it over to hide alarm display. Out of sight, out of mind. The front face of the clock will always show the current time, and will flip to the correct orientation.
