Ryan Pooh-Poohed Those Low-Carb Diets

To keep his roommates from pilfering his beer reserves, Ryan resolved to build a Fort Knox-like protection device. The BeerBot waits for a correct activation code and then pours (drizzles out, actually) beer until a sensor detects the cup is filled. If the thirsty perpetrator enters the wrong code, a speaker sounds an alarm and a counter is incremented-a combo that most assuredly will prevent all but the most foolhardy from attempting another break-in. Ryan now sleeps peacefully knowing his beer is safe and sound.
Check out all the details!
