If you just got a new Apple Watch Series 3 (or are about to), you should think about trading in your old watch.

Cult of Mac has a popular gadget buyback program that pays more for used Apple Watches than competing trade-in services, and it’s a lot easier and safer than Craigslist or eBay.

Amazing AR demo shows off Apple Park

There’s a pretty amazing demo of augmented reality technology at the new Apple Park visitor center.

The visitor center — which opened to the public on Tuesday afternoon — features a large-scale model of the new campus.

The model is large but bare bones. It looks like a classic architectural model with plain mockups of the buildings and the campus’ contours.

But pick up a nearby iPad, point the camera at the model, and it suddenly springs to life with lifelike plants, trees, and details galore. Check out the video below.

iPhone turns 10 This an excerpt from Unsung Apple Hero, an e-book about UI designer Bas Ording’s career at Apple. Ording is responsible for a big chunk of today’s computing interfaces, but is little-known because of Apple’s super-strict privacy policies. Hit the link at the bottom of this post to get a free copy of the e-book.

One of the key design decisions that Apple’s Human Interface Team made early on while developing the iPhone was to go all in on big, simple gestures. They wanted to make a single, simple swipe accomplish as much as possible.

It’s a bit ironic. After investing so much in multitouch technology, which relies on multiple touch inputs, one of Apple’s key edicts was to make as many gestures as possible work with a single finger.

Ex-Apple engineer tells how the company’s manufacturing works

Almost all electronic products are still assembled by hand, even hundreds of millions of iPhones.

But that’s changing. Apple’s supply chain is rapidly automating using AI and robots.

At the forefront of this is an ex-Apple product design engineer, Anna-Katrina Shedletsky, who is using her expertise to help other manufacturers build their products.

On this episode of the Apple Chat podcast, we talk to Shedletsky about her new AI startup, Instrumental; Apple’s giant manufacturing operation; the role of product design; and much more.

If you’re curious how Apple makes its products, listen to the podcast or check out the full transcript below.

PALO ALTO, California — The first iPhone “prototype” was strung together using bits of wood, duct tape and some old Polaroid lenses.

Key members of the Apple team reminisced about those early DIY efforts Wednesday night during a discussion led by Brian Merchant, author of The One Device, a new book about the birth of the iPhone.

“This thing was really kludged together,” said Brian Huppi, a former Apple engineer who helped build the first system. “It was built out of wood, duct tape and old lenses from the ’60s.”

iPhone turns 10 One day in early 2005, interface designer Bas Ording was sitting in a secret, windowless lab at Apple HQ when the phone rang. It was Steve Jobs.

The first thing Jobs says is that the conversation is super-secret, and must not be repeated to anyone. Ording promises not to.

“He’s like, ‘Yeah, Bas, we’re going to do a phone,'” Ording told Cult of Mac, recalling that momentous call from long ago. “‘It’s not going to have any buttons and things on it, it’s just a screen. Can you build a demo that you can scroll through a list of names, so you could choose someone to call?’ That was the assignment I got, like pretty much directly from Steve.”

Birth of the iPhone: How Apple turned clunky prototypes into a truly magical device

iPhone turns 10 The world had never seen anything like the iPhone when Apple launched the device on June 29, 2007. But the touchscreen device that blew everyone’s minds immediately didn’t come about so easily.

The iPhone was the result of years of arduous work by Apple’s industrial designers. They labored over a long string of prototypes and CAD designs in their quest to produce the ultimate smartphone.

This excerpt from my book Jony Ive: The Genius Behind Apple’s Greatest Products offers an inside account of the iPhone’s birth.

On this week’s Apple Chat (the podcast formerly known as Kahney’s Korner): I talk with former Apple product design engineer Anna-Katrina Shedletsky about her take on modern manufacturing and how AI will revolutionize factories. She introduces us to her new company, Instrumental, which is using machine learning to help manufacturers identify and fix problems on their assembly lines.

Using her hard-earned experience at Apple overseeing the production of the first Apple Watch and several generations of the iPod, Shedletsky says machine learning is coming fast to manufacturing. Amazingly, almost all consumer electronics products are still assembled by hand — including hundreds of millions of iPhones.

But that’s changing. Manufacturing is undergoing a huge sea change with the advance of robotics and AI.

Best List: Espin electric bike is a nice ride at a budget price [Review]

Best List: Espin Sport electric bike

I love electric bikes, but a lot of them look butt-ugly. Their batteries and motors are strapped to the frame, ruining their lines. Stromer’s bikes, which integrate motor and battery into the frame, are a notable exception. But the latest Stromers cost an eye-watering $7,000 and up.

Enter Espin’s electric bikes, which look like Stromer’s but cost just $1,888, a steal for an eBike this capable and fun. Plus, they are on sale right now for $1,200, which is a killer deal.
