Leonardo da Vinci: Brilliant bridge from the 3D printer

Leonardo da Vinci, the Tuscan universal genius and painter, who died much too early in 1519, amazes science again 500 years after his death. For researchers and architects have for the first time recreated one of Leonardo’s bold bridge constructions in the 3D printer at the Massachusetts Institute of Technology (MIT). The result: The bridge connecting the center of Istanbul with the Galata district would have worked perfectly and would have been earthquake-proof. With his invention, the tricky Tuscan inventor could have revolutionized bridge building until today.

1502 Sultan Bayezid II planned the construction of the bridge. Da Vinci submitted a draft, which was not realized. For instead of the at least ten pillars, which were then usual for such a bridge, Leonardo wanted to span the river with a single arch. That seemed too risky for the Sultan. Based on the notes and sketches, the researchers at MIT have now built the bridge on a scale of 1: 500 using components from the 3D printer. The 81-centimeter-long model shows that pure gravity would have perfectly connected the stone blocks, without cement, mortar or similar substances. At the same time, the construction would have been so flexible that it would have survived the frequent earthquakes in Istanbul. According to Gizmodo, the bridge builders placed the model on two mobile platforms for this test.

Naughty: Dyson stops his electric car

New setback for James Dyson. After Brexit, who had promised billions in revenue and massive tax benefits from the English vacuum cleaner revolution, is still in limbo, he now had to end his electric car project. In a message to his staff, Dyson said, “Although our team has developed a fantastic car, we do not see any way to make it commercially viable.” The sale of the Dyson car should start in 2021. The construction of the planned factory in Singapore has apparently not even begun. Recently, according to TechCrunch, Dyson had sought a buyer for his car project, but was unsuccessful.

The technology developed for the e-car with novel solid batteries, sensors, robots and artificial intelligence, the company still wants to develop and use for new products. Around 2.8 billion euros are available for this program. Experts suggest that James Dyson had underestimated how fast classic car companies such as VW with their own electric cars on the market – and that he now no longer sees the established competition. The affected nearly 600 employees are to be accommodated in other company areas if possible. “This is not the first project that has changed direction, and it will not be the last,” said Brexit-Dyson. The man knows what he’s talking about.

iPhone 11 load faster – at half price

For the first time, the iPhone 11 Pro and 11 Pro Max ship with a contemporary, fast 18-watt AC adapter, bringing an empty battery to 80 percent in less than an hour. The entry-level iPhone 11, however, still comes with an outdated 5-Watt plug, with which the phone loads drastically slower than it could. If you want to change that, Apple gets the 18-watt PSU of the Pro-iPhones for 35 euros, and the necessary cable from USB-C to Lightning for another 25 euros.

That makes 60 euros for an equipment that would actually have to come from the factory. But now it is also for half, as the magazine BGR reports. Because the Chinese supplier Ugreen has reduced the prices for its iPhone 11 accessories. The 18-watt power adapter now costs 16.99 euros on Amazon, and the Apple-certified USB-C Lightning cable 12.99 euros. Makes a total of 29.98 euros instead of 60 euros. The technique should be largely identical to Apple. And with that the iPhone 11 charges as fast as the Pro and the Pro Max.

Google brings the corrugated iron laptop

Next Tuesday, October 15th, Google will introduce its fall novelties. On the agenda are the smartphones Pixel 4 and Pixel 4 XL, the Pixel Watch and the laptop PixelBook Go with Chrome OS. Many secrets of the new devices are no longer secret, Google itself has spoiled in advance extensively. Apparently the Pixelbook Go should stay under the magic cloak until Tuesday. But did not work, 9to5Google shows the device in advance.

The photos show a laptop with a very smart and catchy orange-pink underside in corrugated iron look. Google calls the color “Not Pink”. When unfolded, the design looks more like a MacBook Air, but with a hint of (distress) pink. Accordingly, the Pixelbook Go comes with a 13.3-inch touch screen, optionally with Full HD or 4K resolution. It can be equipped with the Intel processors m3, i5 and i7. Maximum is 16 GB RAM and 256 GB SSD storage space. The rest of the data should end up in the Google Cloud.

Cassette boom: manufacturers go out of the material

In the course of the music retouch, not only vinyl records but also music cassettes are booming – albeit at a relatively low level. According to Techspot, sales of ready-to-use cassettes in the United States tripled between 2016 and 2018 to 219,000. Tapes like the “Awesome Mix” to “Guardians of the Galaxy” are cult. And that now causes problems in the cassette production. Manufacturers such as the US company National Audio Company can no longer deliver the desired quantities because raw materials such as gamma iron oxide are missing.

The only factory still producing this material was apparently quiet for refurbishment most of the year. As a result, vendors’ inventories are shrinking and cassettes are rising. At the end of the year, however, the production of gamma iron oxide is set to pick up speed again. The demand is likely to be great, now that the soundtrack for the third season of the Netflix sci-fi series “Stranger Things” appears on cassette.

Here cooks the cook. US home appliance maker Charles Kerr has launched a collection of kitchen accessories featuring the portrait of the Apple chef. The “Tim Cookware Collection” consists of, among other things, chopping boards, cooking spoons, pasta roll, cookbook, chef’s hat and a matching cheese grater to the new Mac Pro. The collections carry the very amusing names “11”, “11 Pro” and “11 Pro Max”, it starts at $ 29. And there is also a video in the classic Apple look. The permission of chef Tim did not catch Charles Kerr, “but of course we like to send him a package”.
