Robots and AI assist in designing and building Swiss university’s ‘hanging gardens’

Architecture and construction have always been, rather quietly, at the bleeding edge of tech and materials trends. It’s no surprise, then, especially at a renowned technical university like ETH Zurich, to find a project utilizing AI and robotics in a new approach to these arts. The automated design and construction they are experimenting with show how homes and offices might be built a decade from now.

The project is a sort of huge sculptural planter, “hanging gardens” inspired by the legendary structures in the ancient city of Babylon. (Incidentally, it was my ancestor, Robert Koldewey, who excavated/looted the famous Ishtar Gate to the place.)

Begun in 2019, Semiramis (named after the queen of Babylon back then) is a collaboration between human and AI designers. The general idea of course came from the creative minds of its creators, architecture professors Fabio Gramazio and Matthias Kohler. But the design was achieved by putting the basic requirements, such as size, the necessity of watering and the style of construction, through a set of computer models and machine learning algorithms.

During the design process, for example, the team might tweak the position of one of the large “pods” that make up the 70-foot structure, or change the layout of the panels that make up its surface. The software they created would then immediately adjust the geometry of the overall structure and the other panels to accommodate these changes, making sure it would still safely bear its own weight, and so on.

There are many automated processes in architecture, of course, but this project pushes the boundaries out in the level of final control seemingly given to them. The point, after all, is to make it a genuine collaboration, not just a sort of architectural spell-check that makes sure the whole thing won’t collapse.

“The computer model lets us reverse the conventional design process and explore the full design scope for a project. This leads to new, often surprising geometries,” Kohler said in an ETHZ news post.

Having arrived at a final design, the construction is being accomplished by another human-automation team: a set of four robotic arms operating with one mind to hold multiple heavy pieces (each pod has dozens) in place while humans apply the resin used to keep them together. It’s a step above the technique we saw used a few years ago by the same team when they used robots as automated assistants.

Semiramis is being constructed in the workshop then shipped piece by piece to its eventual home at Tech Cluster Zug. It should be fully assembled and ready to accept soil and seeds this coming spring, so stop by if you’re in the area.

Fairphone hits software support longevity akin to Apple’s iPhone

Fairphone, the Dutch social enterprise dedicated to making consumer electronics (more) sustainable and ethical, including by supporting repairability so that users can hold onto their hardware for longer, has announced public testing of Android 10 for the six-year-old Fairphone 2.

Owners of the modular handset that was first released back in 2015, running Android 5, should expect to be able to upgrade to Android 10 (released date: 2019) in early 2022, Fairphone said today, announcing the beta rollout of the upgrade.

Fairphone stopped producing (but not supporting) the Fairphone 2 back in 2018 — going on to release the Fairphone 3 (in 2019), the Fairphone 3+ (in 2020, also available as a modular upgrade to the 3) and, earlier this fall, the Fairphone 4, its first 5G handset — which it said would be supported until at least 2025.

Given the Fairphone 2’s impending update to Android 10 next year — which will mean it will have been supported for a total of seven years — 2025 looks like a conservative estimate of how long Fairphone 4 owners should expect to receive software support.

Fairphone says it collaborated with its community of users for the Android 10 upgrade project — and with a software developer in India, Bharath Ravi Prakash, which it says worked as a volunteer open source dev — and by doing that says it was able to streamline the process and shrink the time required to carry out the upgrade.

So while the prior Fairphone 2 OS update (to Android 9) took 18 months, this time the process has been condensed to 10 months.

Google, meanwhile, has gone on to release Android 11 (2020) and Android 12 (last month) — for a sense of how far behind the Fairphone 2 upgrades are trailing the latest OS release.

“The company learned a lot from the Android 9 upgrade and although still complex, Android 10 was more predictable than Android 9,” Fairphone notes in a press release, which also quotes its head of software longevity & IT, Agnes Crepet, who writes: “Our unique approach to software has allowed us to help our users keep their devices for as long as possible. We’re pleased to be able to provide our Fairphone 2 community with yet another software upgrade, reaching our goal to provide at least five years of support from launch for our phones and with the Android 10 upgrade, we’re going beyond that to seven years of support. We are constantly raising the bar for ourselves and the industry, showing that doing things more sustainably in software is possible.”

Seven years’ support puts Fairphone into Apple iPhone software support timespans. But of course the average Android-based handset can expect fair fewer years of software love — typically Android smartphones only get around three years’ support. So it’s a major achievement.

And while Fairphone may only now be catching up to Apple on the software longevity front it is already years ahead of Cupertino in another respect: Hardware sustainability through repairability via modular construction and offering direct-to-consumer spare parts.

Earlier this month Apple announced that, starting next year, it would kick off a “Self Service Repair” program — shipping spare parts and repair tools to iPhone and Mac users to let them perform basic repairs at home.

It’s by no means full modularity from the company that has — historically — loved a hermetically sealed, stupidly thin, often literally glued shut box, but it is a small step in a more sustainable direction. And one that Fairphone has long pioneered.

Belkin’s new 3-in-1 wireless charger delivers speedy charging for the latest Apple Watch and iPhone

Belkin has a new 3-in-1 wireless charger that’s tailor made for iPhone and Apple Watch owners, and that also provides MagSafe 15W charging speeds for iPhone 12 and 13, along with fast charging for the latest Apple Watch 7 series. Belikin also introduce a new standalone portable fast charger for Apple Watch that includes an integrated USB-C cable and also offers fast charge compatibility for Series 7 models.

The Belkin “BOOST↑CHARGE PRO 3-in-1 Wireless Charging Pad” which is too much of a mouthful and will henceforth be referred to as the 3-in-1 charger, has a MagSafe 15W wireless charger for your iPhone as mentioned. It also includes a standard Qi-compatible wireless charging pad that you can use to power up your AirPods, and there’s an adjustable Apple Watch charging puck that supports fast charging as mentioned above. The adjustability of the Watch puck is a nice touch, giving you freedom to charge either lying flat or upright in Apple Watch’s ‘nightstand mode,’ and there’s a clever switch underneath that allows you to tweak the height of the stand to perfectly fit Apple Watch models new and old, as well as a side variety of Apple Watch cases if that’s your thing.

The stand is covered in a rubberized silicone so you don’t need to worry about inadvertently scratching any of your gadgets as you fumble in the night, and it’s all powered by just a single cord that plugs into an included 40W power adapter. I’ve been using this for about a week now, and can confidently say it’s the best option out there for a one-cord, max speed bedside charging solution for Apple fans.

It’s $149.95, sold via both Belkin’s own website and Apple’s, and goes on sale starting today.

The Belkin “BOOST↑CHARGE PRO Portable Fast Charger” (again, terrible, so let’s just call it the Watch charger) is an awesome alternative to Apple’s own little standalone pillow charger for Apple Watch. Thanks to the integrated cable it’s super portable for travel, and again features adjustability to fit various Watch models and cases, as well as offering both flat and upright nightstand charging. Plus, you get the fast charging feature if you have a Series 7. Definitely the charger to beat when it comes to dedicated Apple Watch kit.

The Watch charger is just $59.95, which is a steal relative to Apple’s own dedicated magnetic charging dock, and also is available to order starting today at both and

Misty-eyed and bushy-tailed: Meet Hai, the world’s smartest shower head

If you had “my shower head needs a small turbine, a Bluetooth connection, an app and a fine-spray mist” on your 2021 bingo card, congratulations, you win the prize. The prize is knowing that Hai exists — and this fine news story, which will tell you all about how the company raised $6 million to get all up in your biz. And we’ll probably have some good, clean fun — i.e. shower puns — thrown in for good measure.

A propos good measure, that, in a nutshell, is kind of the point of Hai. The founders claim that your daily de-grimification routine is one of the biggest users of water in a residential context. A lot of people care about the environment, but how do you know how much water you actually blast through on your way to a haven of godliness-adjacency? The answer is some really expensive electronics, or this (possibly equally expensive) $250 shower head. Hai is designed to be easy to install and remove using just your hands. Aimed in particular at apartment-dwellers who want “a spa-like shower experience” that they can take with them as they nomad their way from apartment to apartment, the Hai shower head is somewhat of a platform.

“During my 20s I moved to a new apartment every year. One of the things that I looked at every time I moved was the shower. I’m quite tall, and it was very important for me to have a shower that was tall enough — and the pressure was obviously important,” Leah Stigile, co-founder and CEO of Hai reminisced. “I’m a mom to two small children, and the time that I get in the shower every day is crucially important to my personal well-being. As I talked to other people, I realized the ritual of showering is super important to other people as well, but for a whole variety of different reasons. I was inspired to be a part of building a company that delivered an amazing experience but also helps you be mindful of the resources that you’re using.”

It appears that a gaggle of investors agree with the Hai team that this is a space worth exploring in more depth. Trousdale Ventures led the $6 million round, and is joined by Will Smith’s Dreamers VC, A-Rod Corp, The Najafi Companies (owners of the Phoenix Suns and McLaren F1), Amity Supply (Jesse Derris), social media stars Josh Richards and Griffin Johnson, Noah Beck’s Animal Capital (Marshall Sandman), former board member and early investor in Peloton, Howard Draft and Local Globe.

“We invested in Hai because they have created an innovative, high-quality showerhead that meets consumer demand for sustainable home products,” said Phillip Sarofim, founder of Trousdale Ventures. “We believe that Hai delivers the best shower experience as consumers continue to shift toward personalized and environmentally conscious products.”

“You are looking at a $9 billion market. In my calculation when you look at the size of the space, there’s room for five or six big new entrants in this market. The interesting thing is that the $9 billion has been carved out by the same five companies for the last 75 years. What is interesting is that brand was almost irrelevant in the space,” explains Leonard Brody, co-founder of Hai. “More than 85% of millennials said the shower was the most important self-care ritual in their home, but the vast majority of them couldn’t tell you the brand of shower head they stood under every day. That is highly unusual in a consumer space. I bet you 60% of the same people could tell you what toilet paper brand they use.”

Hai’s shower head was super easy to install — taking the old shower head off took longer than installing the new one. Best of all: No leaks and no tools required. Photo by Haje Kamps for TechCrunch

So, with a huge market and no clear winner, we’ve seen a number of new companies enter the fray. It seems like the newest dribble of companies started with Kickstarter darling Nebia pre-selling $3 million of fine-misting shower heads back in 2015, before raising investment from, and later getting swallowed up by, bathroom giant Moen.

“One of the largest wastes of water in the shower is actually when you flip on the water and you wander away and are busy while you’re waiting for it to warm. The shower is running and before you know it you’ve done three loads of laundry. We’ve developed a little hydropower Bluetooth turbine and it does a couple of things. First of all, it powers the LED light on the shower that will notify you when the water is warm and ready to get in. Also, if you’ve wandered away, it’ll send you a push notification to your phone,” explains Brody. “Secondly, with a partner app that we developed, it will you can set the number of gallons of water that you want to use during your shower. The average shower is about 20 gallons of water. You can configure that, of course, but our product default is set to 20 gallons. When you hit that limit, a little light will notify you, reminding you to wrap up and hop out of the shower.”

The device tracks your water consumption over time, which takes care of one of the first challenges of awareness; namely, awareness. The company suggests that by measuring your baseline and then setting goals for yourself, you can do your bit for the environment and use a bit less water. The company also wants to use the data it gathers to make the shower experience more custom.

“The next step on the roadmap for us that’s coming in early 2022, we are taking our product and adding a layer of consumables. First up, we have what we’re calling infusions. We’ve developed a single-use no-waste pill that can be added to a capsule that fits onto the existing showerhead,” explains Stigile. “You can infuse aromatherapy or hair and skin treatments directly into the water. That really helps deliver that spa experience that we are trying to create in your home bathroom. And then the next step beyond that is filtration. With the sensors we have, we can actually be quite sophisticated about telling you what’s in your water delivering, a very personalized experience. We can even take the temperature you like to shower at into consideration and recommend the consumables that are best for your particular use case. That’s a huge opportunity there for us.”

The company only started shipping its products a few weeks ago, but so far they’re off to a lather good start, with promising sales through its direct channels and retail presence on the Bed Bath & Beyond website and its New York flagship store.

Gift Guide: 20+ STEM toy gift ideas for aspiring young builders

Welcome to TechCrunch’s 2021 Holiday Gift Guide! Need help with gift ideas? We’ve got lots of them. We’re just starting to roll out this year’s gift guides, so check back from now until the end of December for more! 

For this year’s STEM toy gift guide we’ve split out our recommendations by age for easier navigation. The 20+ gift ideas (below) run the gamut from train sets controlled by colorful blocks, to robots that can draw, all the way up to a cute DIY handheld gaming console that’s really an experimental platform for teens to build on.

Gifts we’ve selected hit a range of price points — starting at $15 and topping out at just under $550 (for all the educational LEGO your kid could ever need!), with a spectrum of price points in between.

The learn-to-code category as a whole continues to mature, showing a strengthening (and welcome) focus on art and design, not just pure engineering. At the same time, it’s clear that sustaining a business selling educational gizmos/games is challenging, with a number of players winking out of existence (or taking an exit) since we last checked in. Product novelty also feels like it’s diminishing, even as maker hardware itself is flourishing (thanks to the likes of the Raspberry Pi). But, in general, the category’s experimental “Cambrian explosion” moment seems to have passed — and the programmable robots have (mostly) taken over.

Consolidation remains a big theme in the space. As do pivots (see: Kano’s new jam, for example). After all, kids are fickle and even the fanciest toy can soon be discarded for a newer, shinier thing. Plus, it feels like some of the earlier hype (and loud claims) — around gizmos that “teach coding” — has faded to a more practical/realistic and less flashy projection of potential educational value.

One extra challenge for STEM toy makers is the (now) high concern over kids’ screen time. Hence lots of products feature marketing that loudly touts “screen-free” alternatives to teaching coding (such as by using physical blocks/cards/buttons etc). Meanwhile some others that do require a screen to work are trying to distinguish what they’re offering as “good screen” time versus the addictive “digital sugar” of non-learning-focused games and/or social media … whether parents buy that remains to be seen.

For surviving STEM players, increasing amounts of their time and energy are being directed away from the consumer space and toward supplying schools with learning-geared kit and resources directly — chasing a more reliable revenue stream, although selling to schools is no cake walk, either. Overall, being part of a larger maker marketplace or broader group of educational businesses seems to be where many surviving STEM startups are headed.

CodeSpark Academy

LA-based startup CodeSpark has been making mobile and web games to teach kids coding for years — now as part of the Homer early learning group after being acquired by its parent company, New York-based BEGiN, earlier this year.

If your youngster already has access to a tablet, CodeSpark‘s pitch for its learning games is “screen time you can feel good about” — saying they cover basic concepts of computing coding (such as sequencing, loops, conditional statements, events, boolean logic and sorting, etc.) — just cunningly disguised as cartoonish characters and fun-looking puzzles and challenges. So kids won’t even realize they’re learning.

Osmo Explorer Starter Kit

Indian edtech giant Byju-owned Osmo has been making educational games for tablets for almost a decade. Its big twist is to combine physical (offline) play (pens, blocks, cards, etc.) with digital on-screen content and interactions.

It does this via a dedicated tablet stand that adds a reflector to the iPad’s front-facing camera so that it gets a view of the physical play area directly below the screen. This means the app is able to mirror/act on what the kids are doing in the physical space. (And the bounded view means the camera only captures tiny hands, not your kids’ faces, so that’s a plus for privacy.) Osmo calls this blend of physical-digital play “embodied learning.”

The Osmo Explorer Starter Kit is described as its “most complete STEAM learning kit yet” — with a range of interactive games and art supplies in the bundle (Note: A tablet is not included so you’ll need your own iPad or equivalent). The kit includes a set of coding-focused games that let kids manipulate on-screen characters to progress by combining (physical) coding blocks into a set of instructions and tapping the screen to execute their (proto)program.

Robo Sense

European startup Robo Wunderkind has built a STEM-learning business, one modular robotic block at a time. Kids get to learn about circuits and engineering concepts by plugging a variety of its smart blocks together — to build their own robots and make them move or otherwise animate them. Creations can be further extended by adding (actual) LEGO bits and bobs.

As well as pure physical play, Robo Wunderkind has a digital aide in the form of a companion app that expands the learning into on-screen coding. Here it offers tiered complexity — with three different levels from coding basics, where kids may just be manipulating colorful icons, to doing drag-and-drop block-based coding (based on Scratch) — which introduces more complex concepts like variables, functions, operators and input/output handling. Python and Arduino APIs are also supported for more advanced programmers. 

The Robo Sense kit offers a taster of Robo Wunderkind’s approach, with a handful of sensing blocks to play with plus over 30 projects and tutorials to access online or in-app.

Artie Max

Artie Max is the latest programmable robot from Educational Insights. Much like its predecessor, Artie 3000, the STEM toy combines programming and art in a very literal sense: The robot is designed to hold colored marker pens and kids write code that the bot “draws” by moving around on a piece of paper.

Educational Insights' Artie Max coding robot shown with the box, colored marker pens and an instruction booklet

Image Credits: Educational Insights

Artie Max’s main upgrade versus Artie 3000 is that it can hold a bunch of marker pens, not just a single marker — allowing for multicolored designs to be coded. Programming Artie’s movements is done via a drag-and-drop interface in the companion app or web interface. Other coding languages are supported, along with a visual interface where kids can draw a design on screen that they want the bot to ink out on paper.

AdaBox is a quarterly (i.e., once every three months) subscription box of DIY electronics projects, curated by AdaFruit. You won’t know what electronics bits and bots you’re getting in advance — but, for more advanced teens with access to a computer this blackbox of hack-together hardware could be just the inspiration they need to get building.

AdaFruit says the subscription service is “designed for makers of all levels, with a special focus on folks just starting out.” Tutorials and videos are provided via the Learning System on its website. Access to an internet-connected device is required for programming the hardware.

Projects in past boxes include building your own Matrix Portal Flow Visualizer.

(Note: There is a dedicated “Give” option for gifting the AdaBox during checkout. However with the holiday season fast approaching, AdaFruit says the first box of any new orders won’t now ship til spring — so ordering this as a holiday gift will require a little patience in the recipient.)

Price: $60 per box

Why not buy your game-developer-in-training this tiny, Raspberry Pi Pico-powered handheld gaming system from U.K.-based Pimoroni — which is not just a teeny games console but an experimental gaming platform.

Games can be coded for the PicoSystem using a variety of languages, including C++/MicroPython (Per Pimoroni: “Our official PicoSystem API is designed to be lightweight, easy to use and to not get in the way while you’re developing games”) — see their tutorial to get started.

Out of the box, the tiny handheld ships flashed with Super Square Bros. by Scorpion Games.

Piper Make Starter + Robotics Expedition Kit

Piper is another longtime player in the STEAM toy space — starting out back in 2014 offering a DIY Minecraft computer to teach kids coding. It’s still selling its classic, wooden-cased Raspberry Pi-powered computer kits but has expanded to sell a range of maker kits.

Including — new for 2021 (and slated to ship this month) — the Robotics Expedition Kit, which comes bundled with the requisite Pi Pico (and other starter electronics essentials). Kids get to build a couple of kinetic robots (a walker and a rover) and then get help to write code to get them moving them via Piper’s drag-and-drop coding platform Make. So they’ll need access to a computer or mobile device.

Piper’s coding platform includes a virtual representation of the microcontroller and automatic translation of the block-based programming language to text-based CircuitPython to support youngsters to learn the basics of hardware coding.

A variety of other projects are also available via the Piper Make portal — where it says it uses storytelling-based lessons to motivate young learners. Its Make programming software is also available via a mobile app.
