Unconventional Switch: Bar Notification

For our unconventional switch, we decided on a design that was both unique and practical. We wanted to answer the question of how to request service at a noisy and crowded bar. The solution we came up with, fitting the project requirements: a simple circuit that lights up an LED when a drink is placed on it. In practice, this would let the bartender know that your drink is empty or that you would like attention. 

For the prototype we built in class, we used two strips of copper tape affixed to a wooden stand to form a break in the circuit, with a metal drink can used to complete it. In a final product, the method for achieving this would likely be different, as condensation from the cup would damage the circuit. For a revision, we would use a rubber pad with a conductive material on the underside to complete the circuit. That way, any drink container could be used regardless of material, and the circuit would be protected from water damage.
