LAS VEGAS — Keith Nothacker is living proof that persistence pays off.

Cult_of_Mac_CES_2015 Nothacker is here at the giant International CES gadget show to introduce a key-size version of his pocket breathalyzer — the first personal, police-grade breathalyzer approved by the Food and Drug Administration. Connected by bluetooth to your iPhone, a quick puff into the $49 BACtrack Vio will tell you instantly if you’re too juiced to drive — or take part in any other activity best done sober.

But 13 years ago, Nothacker was fighting the FDA to bring the device to market.

LAS VEGAS — For more than 10 years, Michael Wallace and Darin Barri were toy designers. Depressed about plummeting sales because of video games, the pair went on a week long bender to drown their sorrows.

They both loved lychee martinis, which are tricky to make. They dreamed of a smart cocktail mixer that uses weight — rather than volume — to make mixed drinks. So they hacked a kitchen scale with some electronics and coded an app. The resulting system, called Perfect Drink, makes it impossible to screw up martinis and dozens of other cocktails. They took it to Brookstone, who loved it and put it on the market. Eighteen months later, they’ve sold 120,000 units.

Now they’re back with Perfect Bake, a foolproof baking system that uses the weight of ingredients, rather than volume, to guide clueless home bakers.

SAN FRANCISCO — Since Apple won’t be selling the iPhone 6 in China for some time, early buyers of the smartphone have an opportunity to make a quick profit by reselling the hot handset on the gray market.

The first 50 people in line at Apple’s San Francisco store this morning appeared to be iPhone resellers — a pattern that seems to be  have been repeated worldwide on the first day of iPhone 6 sales.

Macworld 2014 SAN FRANCISCO — Right in the middle of the Macworld show floor, there’s a circle of 12 tables. They’re showing off a range of cool gadgets, like a combination battery/wall charger and a clever foldable iPhone stand.

The dozen products all started life as successful Kickstarter projects, and can be found for sale on BiteMyApple.co, an online store that sells Apple-related Kickstarter products.

The site is the brainchild of Chris Johnson. After founding the site three years ago, Johnson has grown it from $45,000 in annual revenues to more than $500,000. He runs the whole operation himself out of his small apartment in New York.

He’s even making a profit on the 12 tables here at Macworld.
