A Windowless Elevator With A 360º Panoramic View

August 20, 2016 by Cameron Coward 23 Comments

The Amoreiras Tower, in Lisbon, Portugal, recently added a rooftop viewing area that is open to the public. The top of the tower is one of the highest spots in the city, and the viewing area gives an impressive 360º view of the surrounding area. However, the elevator to get to the top left a lot to be desired. It’s an interior elevator, and didn’t itself offer any view.

So, Artica, along with Schindler, were brought in to solve that problem. The solution was to mount displays on the interior of the elevator, in order to simulate a 360º panoramic view of the city outside. The video is synced up with the elevator, so the view changes as the elevator passengers move up and down between floors.

Artica, who was responsible for the concept, design, and electronics installation accomplished this by first building a prototype in their office building. This was a full-size elevator replica with which they could test the design and get it ready for installation. They then partnered with Schindler to actually install the system in the elevator of the Amoreiras Tower, which necessitated almost completely rebuilding the elevator. As you can see in the video, the resulting view and accompanying music (definitely not elevator music) are fantastic, and it was even done in time for the public opening of the rooftop viewing area.

Like us, you may be wondering where the video footage came from. The scene moves in apparent parallax so video was obviously captured with continuous motion and isn’t a scrolling image. This is the work of a camera toting drone.

Inside A Circuit Breaker With MikesElectricStuff

February 26, 2016 by Brandon Dunson 25 Comments

High voltage is not something we usually tinker with at home. In fact, most of us are more comfortable working with non-lethal, low current, low voltage DC signals. When we do venture into the world of high voltage, we prefer to do it vicariously thru someone with more safety training and/or experience.

[Mike] shows us the inner workings of a 240VAC circuit breaker and explains how the different safety features in the device work. In proper MikesElectricStuff form, [Mike] finds out what it takes to destroy the device. Or in this case multiple devices, [Mike] uses his “Destruct-o-tron” to create catastrophic failure in more than one breaker. You can check out the video embedded after the break to learn a bit about how a circuit breaker works, and of course witness the carnage.

WingBoard: Wakeboarding Behind An Airplane

January 10, 2016 by Brandon Dunson 36 Comments

[Aaron Wypyszynski] or [Wyp] for short had a dream as a youngster about jumping out of a plane and “carving through the sky” (paraphrasing the video embedded after the break), so when he grew up [Wyp] went ahead and pursued that dream.

What that boyhood dream produced is [Wyp] offering to pull you through the sky on what looks like a proper model of a blunt nosed paper airplane glider. Seems to be a bit like wakeboarding for skydivers, cause that needed to be a thing.

Deployable By Design With Bunnie Huang, Nadya Peek, And Joi Ito

December 2, 2015 by Brandon Dunson 10 Comments

We follow [bunnie]’s blog as he posts interesting and usable information quite regularly. [bunnie] posted about a video of a recent talk he did at MIT Media Lab with Nadya Peek and Joi Ito. This was in lieu of his monthly “name that ware” competition, which is worth looking into as well.

The talk is focused on small volume manufacturing and the experiences that the speakers have under their collective belt is large enough that the conversation takes a turn from how to do things in practice, to the theory and technique of manufacturing on a philosophical level.

[bunnie] prefaces the conversation with an explanation of some of the design and manufacturing processes involved when working on the circuit stickers project. He talks about the importance of testing the product and the complex test jig that is required to quality check a simple (in comparison to the test jig) product. [bunnie] shares an overview of the project timeline and where some extended design stages might be found in unexpected places.

The design and manufacturing process is discussed on many levels throughout the talk. Among the points that are insightful, we certainly found ourselves a little jelly of all the time [bunnie] gets to spend in Shenzhen.

If you’re not familiar with [bunnie]’s blog you can check it out at www.bunniestudios.com. Pro Tip: you can spend the better part of your workday browsing topics in the sidebar on the right.

We have covered the MIT Media Lab before, including a trip to Shenzhen that is discussed in the Media Lab talk by [Joi] and [bunnie]. Another interesting interview at SXSW earlier this year by [Sophi Kravitz] who spoke with [Sunanda Sharma] about mediated matter.

Congo’s Space Program

November 1, 2015 by Will Sweatman 29 Comments

Deep in the hills of the Democratic Republic of Congo, you’ll find men and women hard at work providing a living for their family. You might find some working in one of the nation’s mines which are rich in natural resources. Others will be working the farms or participating in one of many diverse cultural customs. If you head two hours via dirt road from the capital city of Kinshasa, however, you’ll find something a bit out of place for the area – an active space program.

On a vast yam farm, [Jean-Patrice Keka] has single-handedly developed several rockets that have flirted with the elusive zero gravity environment. [Mr. Keka’s] ‘Mission Control’ is a corrugated metal shed lined with CRT monitors and dated computers, but don’t let this fool you. His vision and drive are just as great as any space faring nation.

His intellect has made him a small fortune in commodities trading, and allows him the luxury to finance his operation without the need of government help. From time to time, he employs the help of local engineering students to get his rockets off the ground. Their payload has included rats and insects, with one launch reaching 10 miles of altitude and the current project aiming for 120 miles. [Mr. Keka] has become a national hero via the televised broadcasts of the launches, and has gotten the attention of national government officials. They even flew him to the US once to petition funding for his work.

[Mr. Keka] and his story should serve as an inspiration to all inspiring hackers and makers to pursue their dreams.

Thanks to [Cmh62] for the tip.

Massive Tesla Coil Plays Music In The Snow

January 11, 2015 by James Hobson 15 Comments

One of our tipsters stumbled across a pretty impressive video of a giant Tesla coil playing music — in a snowy forest! The forum showing off the video is in Finnish but Google Translate does a pretty good job getting the point across.

This massive Tesla coil dubbed the BiggerDR was built by [Kizmo], who lives way up north in Finland. He was originally inspired by another build and decided to try his hand at making one. The Tesla coil, detailed in another forum post (in English this time) has some pretty impressive specs. The coil alone has 1550 wraps! Not too mention a pretty impressive bank of capacitors in series…

His YouTube channel has some great videos of the build — in fact, he’s been messing around with Tesla coils for at least 7 years already — stick around after the break to see BiggerDR in action.

DIY USB Spectrometer Actually Works

July 31, 2014 by Will Sweatman 32 Comments

When we hear spectrometer, we usually think of some piece of high-end test equipment sitting in a CSI lab. Sure, a hacker could make one if he or she put their mind to it. But make one out of a webcam, some cheap diffraction grating purchased off ebay and some scrap? Surely not.

[Renaud] pulls off this MacGyver like build with a detailed knowledge of how spectrometers work. A diffraction grating is used to split the incoming light into its component wavelengths. Much like a prism would. The wavelengths then make their way through a slit, which [Renaud] made from two pieces of highly polished brass, so the webcam sensor can see a specific wavelength. While the spectrometer-from-webcam concept isn’t new, the build is still impressive.

Once the build was complete, [Renaud] put together some software to make sense of the data. Though a bit short on details, we hope this build will inspire you to make your own spectrometer, and document it on hackaday.io of course.
