Folding is ubiquitous in nature with examples ranging from the formation of cellular components to winged insects. It finds technological applications including packaging of solar cells and space structures, deployable biomedical devices and self-assembling robots and airbags. Here we demonstrate sequential self-folding structures realized by thermal activation of spatially-variable patterns that are 3D printed with digital shape memory polymers, which are digital materials with different shape memory behaviors. The time-dependent behavior of each polymer allows the temporal sequencing of activation when the structure is subjected to a uniform temperature. This is demonstrated via a series of 3D printed structures that respond rapidly to a thermal stimulus and self-fold to specified shapes in controlled shape changing sequences. Measurements of the sp...

When is Pancake Day 2019 and some alternative crepe recipes to celebrate Shrove Tuesday

With Pancake Day nearly upon us and it time to stock up on the essentials to make the perfect tasty treats. But you don’t have to stick to the basics of lemon and sugar or chocolate spread and banana, as we have rounded up some alternative recipes for you to try out from gluten free and buttermilk and apple to mango mojito and tiramisu. Always the days before the start of Lent in the religious calendar, Shrove Tuesday sparks the beginning of the 40 days leading into Easter. This year Pancake Day falls on March 5. The tradition of eating pancakes comes from families using up all of the treats in their kitchen cupboards in the form of pancakes, ready to start Lent the next day, where they give up something (usually chocolate, sweets or alcohol) for Lent. The ingredients for pancakes are said to symbolise four points of significance at Easter and springtime of the year – eggs signify creation, flour is said to be the staff of life, salt is for wholesomeness and milk symbolises purity. Shrove Tuesday dates back many years to Anglo-Saxon times when Christians would go to confession and were ‘shriven’ (acquitted from their sins). A bell would be rung to call people to confessio...

It Looks Like Jets Coach Adam Gase’s Burner Account May Have Been Uncovered

Twitter users are convinced they’ve found Adam Gase’s rumored burner account. And the evidence is pretty convincing.  In a recent New York Daily News report, a source claimed the New York Jets coach—or someone close to him—had a fake social media account that was used to clap back at his haters. The allegation further underscored Gase’s reputation within the franchise as “an insecure guy” who could not handle criticism … at least, not in a mature way. In fact, some people on One Jets Drive are convinced Gase or a family member has a burner Twitter account to monitor what is being written or said about him — and defend him if necessary. Gase didn’t respond to several requests from the News for this story. In the report, insiders addressed Gase’s so-called inflated ego and the ways in which he responds to critics who say he is an unfit leader. Sources say the coach has expressed indifference toward the critiques, and simply responds with lazy, cocky lines; his most of favorite of which is said to be, “I’m rich as fuck.” Yes, it’s an immature defense, but probably true. Shortly after the Daily News story was published, Ke...

This presentation covers the characteristics and needs of Twice Exceptional youth and how finding the right fit

This presentation covers the characteristics and needs of Twice Exceptional youth and how finding the right fit for your child can make the difference between triggering a meltdown or stimulating a life-long love of learning. Visit the school and discover the magic of empathic, patient teachers, a highly-skilled clinical team, and  rigorous, creative curricula that is driven by student interest, voice, and capability. Students learn how to sew on a real sewing machine while making friends with other American Girl Doll Fashionistas. First they choose their dress fabric from a variety of colors and prints (all cotton). Then they start to sew and assemble the garments. The final step is to decorate each dress with sparkle, ribbon, and lace. The TFC dress design will fit all American Girl Dolls and other similar 18″ dolls (Our Generation, My Life and Journey Girls). Propelled by the infectious Brazilian-infected score, this dazzling fable about a small boy tracing his missing father’s footsteps from a rural cain to the big city (and beyond) doesn’t need words.

We Do It Together Blog: “Lee’s iconic fighting style, Wing Chun, was developed by a woman,

We Do It Together Blog: “Lee’s iconic fighting style, Wing Chun, was developed by a woman, intended for a woman and named after a woman,” Natasha Choi writes I’m a short, skinny looking girl with twig like arms and baby fat cheeks, so he last thing people would associate me with is being a martial artist. More likely, when the words “martial artist” are uttered, the image associated is an old Asian grandmaster that can kick serious ass, or the “Bruce Lee” hero type. Which is why I was surprised to learn that Bruce Lee fights like a girl. When I first arrived in L.A., I joined a school-run drop in class for stage combat. There, I met stunts coordinator Jack C. Huang, who would later become my mentor or what we call “sifu.” While the class is intended for stage- or film-based stunts, Jack would also teach us the traditional movements of Tai Chi, Taekwondo and most notably Wing Chun. What intrigued me most about Wing Chun was how well it coincided with my own movements — the gracefulness I had from being a ballerina, plus the speed of my slim figure. Almost like it was a fighting style intended for me. According to the Asian folklore, Wing Chun dates back two centuries with the bu...

By supercharging the resolution with a 24.1-megapixel CMOS sensor and removing the optical low-pass filter to

By supercharging the resolution with a 24.1-megapixel CMOS sensor and removing the optical low-pass filter to capture finer detail, the Nikon D7100 delivers the best image quality we’ve ever seen in a Nikon APS-C-type DSLR. Add in a new 51-point autofocus system, full 1080p HD video recording with full-time AF, a nifty 1.3x crop mode that extends the camera’s reach, and many more advanced, near-pro-level features, and it’s clear the D7100 is a serious tool for shooters who want to get more serious about their photography. Solid, ergonomic body design; Stunning, highly detailed photos, thanks to 24.1MP sensor upgrade and removal of optical low-pass filter; Cool 1.3x crop mode extends reach to nearly 2x the full-frame equivalent; Records Full 1080p HD video at up to 30fps with full-time AF; Many pro-level features packed into a consumer-friendly body at reasonable price. Shallow buffer that hampers continuous burst shooting; AF slightly slower than average for its class; No real-time aperture control while in Movie mode (among other quirks); More noticeable moire patterns and aliasing artifacts (but only found when shooting fabrics with strong, distinct patterns)...

ARMing A Breadboard — Everyone Should Program An ARM

I’m always a little surprised that we don’t see more ARM-based projects. Of course, we do see some, but the volume isn’t what I’d expect given that low-level ARM chips are cheap, capable, low power, and readily available. Having a 32-bit processor with lots of memory running at 40 or 50 MIPS is a game changer compared to, say, a traditional Arduino (and, yes, the Arduino Due and Zero are ARM-based, so you can still stay with Arduino, if that’s what you want). A few things might inhibit an Arduino, AVR, or PIC user from making the leap. For one thing, most ARM chips use 3.3V I/O instead of the traditional 5V levels (there are exceptions, like the Kinetis E). There was a time when the toolchain was difficult to set up, although this is largely not a problem anymore. But perhaps the largest hurdle is that most of the chips are surface mount devices. Of course, builders today are getting pretty used to surface mount devices and you can also get evaluation boards pretty cheaply, too. But in some situations–for example, in classrooms–it is very attractive to have a chip that is directly mountable on a common breadboard. Even if you don’t mind using a development board, you may want to...
