Here is a gadget I would love to go buy, a mini fridge which loads upto 24 beer cans. No need to open up the fridge to crave your thirst, as the fridge will throw beer cans at you using a mini catapult located at the top. The beer launches and angle are controlled remotely, and by looking at the video I can say that it is very accurate. Sadly it is not available for purchase.

Almost all of the raw materials for the refrigerator were purchased from McMaster-Carr, some motors came from Jameco, and the switches/potentiometer were purchased at RadioShack. In total the beer launching refrigerator uses 3 limit switches. Two of which are triggered when the elevator reaches the top or bottom of its travel, and one is triggered when the catapult arm is fully cocked. I also have a potentiometer that is connected to the rotating catapult platform. The voltage across the potentiometer is read by the microcontroller to sense the angle of the catapult platform.
