3D Printer Gives You Chocolate When You Work Out

If being chased by imaginary zombies doesn’t speed up your run, you may need to take more drastic measures—like rewarding yourself with chocolate. EdiPulse, a project from Rohit Ashok Khot, Ryan Pennings, and Florian "Floyd" Mueller at Exertion Games Lab in Australia, combines the wearables trend with 3D printing in order to gamify exercise and produce visible rewards. 

The EdiPulse uses a Polar heart rate monitor that measures beats per minute, and sends that information through to a mobile app. The data gets saved on the Polar website, and once the workout is complete, the app translates the data for the 3D food printer. The printer then prints either a chocolate message or emoticon. The harder you work, the thicker the chocolate.

In order to determine the number of chocolate layers printed, heart rates are divided into four zones: very light activity, light activity, moderate activity, and hard activity. If your heart rate stays between 50 and 70 BPM— generally considered a normal resting heart rate—you’ll get one layer of chocolate. From 71 to 110 BPM, you get two layers; 111 to 140 BPM results in three layers; and 141 to 180 rewards you with four.

Each activity zone also corresponds with a different emoticon. Maintaining a steady workout in the hard activity zone rewards you with a much-deserved giant smile or a cheerful message. But stay in the very light zone, and you’ll get a frown.

When the 3D printer randomly selects a cheerful message instead of an emoticon, the message’s length varies by your workout time. Workout duration is divided into 5 minute intervals, and each interval equals one printed letter. So if you work out for 30 minutes, you’ll get the first 6 letters of a message like “Well done, Mate!”

The intention behind EdiPulse is to encourage exercisers through a tangible final product. While knowing that you’ll get more toned may enough to push you to actually use that gym membership, others might need an instant visual to keep them going.

And don't worry: The developers kept in mind the calories and sugar content and measured out the chocolate dosage so eating the reward won’t negate the workout.

While the project report [PDF] says that people may end up giving the chocolate away or throwing it out, it seems hard to imagine that anyone who would buy the EdiPulse wouldn’t want to eat their hard-earned candy.

Designer Kelli Anderson's new book is for more than just reading. This Book Is a Planetarium is really a collection of paper gadgets. With each thick, card stock page you turn, another surprise pops out.

"This book concisely explains—and actively demonstrates with six functional pop-up paper contraptions—the science at play in our everyday world," the book's back cover explains. It turns out, there's a whole lot you can do with a few pieces of paper and a little bit of imagination.

There's the eponymous planetarium, a paper dome that you can use with your cell phone's flashlight to project constellations onto the ceiling. There's a conical speaker, which you can use to amplify a smaller music player. There's a spiralgraph you can use to make geometric designs. There's a basic cipher you can use to encode and decode secret messages, and on its reverse side, a calendar. There's a stringed musical instrument you can play on. All are miniature, functional machines that can expand your perceptions of what a simple piece of paper can become.

How IKEA Turned the Poäng Chair Into a Classic

Ikea

IKEA's Poäng chair looks as modern today as it did when it debuted in 1976. The U-shaped lounger has clean lines and a simple structure, and often evokes comparisons to Finnish designer Aalto’s famous “armchair 406.” Its design, however, is ultimately a true fusion of East and West, according to Co.Design.

In 2016, the Poäng celebrated its 40th birthday, and IKEA USA commemorated the occasion (and the 30 million-plus Poäng chairs they’ve sold over the years) by releasing two short videos about the armchair’s history and underlying design philosophy. Together, they tell the story of a fateful collaboration between Lars Engman, a young IKEA designer, and his co-worker, Noboru Nakamura.

Nakamura had initially come to IKEA to learn more about Scandinavian furniture. But the Japanese designer ended up imbuing the Poäng—which was initially called Poem—with his own distinct philosophy. He wanted to create a chair that swung “in an elegant way, which triggered me to imagine Poäng,” Nakamura recalled in a video interview. “That’s how I came up with a rocking chair.”

“A chair shouldn’t be a tool that binds and holds the sitter,” Nakamura explained. “It should rather be a tool that provides us with an emotional richness and creates an image where we let go of stress or frustration by swinging. Such movement in itself has meaning and value.”

Save for upholstery swaps, a 1992 name change, and a new-ish all-wooden frame that's easily flat-packed, the modern-day Poäng is still essentially the same product that customers have purchased and enjoyed for decades. Devotees of the chair can hear the full story by watching IKEA’s videos below—ideally, while swinging away at their desks.
