The last time I tried making beer, we were up until 3AM standing in a kitchen that looked like tornado had struck. My last wine-making attempts ended in grape-flavored vinegar. Even PopSci staff photographer John Carnett (or rather, his wife) endured a wort explosion the first time he tested his prototype DIY all-in-one brewing machine. Clearly, adult-beverage-making benefits from precise control and automation. Check out a few of my favorite electronic brewing projects after the jump.
If you like beer, then perk up those ears, for we have news of an innovation – brought to you by, who else, the Germans – that could lead to longer-lasting brews. The development in question is a polymer that extracts riboflavin, a micronutrient found throughout beer and other beverages that promotes spoilage when exposed to light.
A veteran of the TV show Battlebots, Jamie Price has built plenty of destructive machines. But late last year, he designed a robot with a more mellow calling: offering cold beer and cocktails. The result — a masterpiece of plywood, plastic, aluminum and electric motors called Bar2D2 — serves up everything but the sage advice.
Software engineer Steve Struebing put a lot of work into a device that helps him to be lazy. Using a Construx toy set and a servo motor, he built a frame to hold a bottle of his favorite beer. He then created a Web application for his iPhone to communicate with a control module that pivots the frame. As he tilts the iPhone, the frame tilts accordingly, for a perfect pour every time.

What: Perfect single-crystal diamonds of more than two carats
(the average engagement ring is less than a carat) churned out in a day. Scientists create the gemstones using a process called chemical vapor deposition (CVD), which grows diamond crystals one carbon atom at a time.
