I’ve been posting a lot about 3D printing recently so I decided to share something a little more analogue today. This is the Triangle Notebook created by Tan Mavitan. It was being sold as a part of “Destination Istanbul” Exhibiton in MoMA Design Stores, but not sure if it still is. Pretty neat notebook and I hope to acquire one someday.

The company Carbon3D came out of two years of stealth mode Monday night with a simultaneous TED Talk and Science paper publication. Their new tech, which they say could be used in industrial applications within the next year, makes coveted 3-D printers the likes of those sold by MakerBot look like child’s play.
Unlike conventional 3D printing, this printer continuously forms a new object, rather than printing it in layers. As a result, it’s much faster than conventional 3D printing (it takes minutes, instead of hours). There are a few different types of existing 3D printers, but they mostly work via the same principle: a printing head passes over a platform over and over, depositing layer after layer of a material like plastic in a precise pattern. Over time, these layers combine to form the desired object — much like a paper printer forms text on a page by putting down row after row of ink. By contrast, this new continuous 3D printer would do away with the layers entirely. Instead, a platform draws the object continuously out of a bath of liquid resin.
The resin solidifies when ultraviolet light hits it (a process called photopolymerization). So to create the desired item, a projector underneath the resin pool shoots UV light, in the form of a series of cross-sectional images of the object. Light, in a sense, is the blade that the printer uses to sculpt its products. Meanwhile, oxygen prevents this reaction from occurring — so to stop the object from simply hardening and sticking to the floor of the pool, there’s a layer of dissolved oxygen there, creating an ultra-thin “dead zone” at the very bottom.

What do you do if you want to 3D print in any direction, but can’t buy a pre-made pen like the 3Doodler? If you’re Vimal Patel, you build your own. He melded a hot glue gun with a powered Lego mechanism (really, Technic) to extrude filament in any axis. To call it bulky would be an understatement, but it works — as you’ll see in the video below, it can produce fairly complex objects as long as you have a keen eye and a steady hand. And if you want to try it, you can. Patel has posted his Lego Digital Designer file for the 3D printing gun, so it shouldn’t be too hard to replicate the invention at home.

UberBlox is a new high-quality metal construction set and prototyping system for makers to build rigid structures and automated machines.
At the heart of the system is a new single-connector locking mechanism which uses a common small tool to quickly and precisely lock each block to the next. The firmly connected blocks provide accurate, strong and rigid frames for a wide variety of structures and complex machines such as robots, CNC machines and 3D printers.
In addition to the basic blocks, the system includes a growing catalog of compatible and reconfigurable parts, including moving components, sub-assemblies, motors, electronics and controllers based on popular boards such as Arduino and Raspberry Pi, for a complete solution to the building needs of today’s sophisticated maker. According to UberBlox founder Alex Pirseyedi,
We believe the time is right to bring a sophisticated high-quality construction system and prototyping set, backed by great support and community engagement, to makers of all levels.
Ultimately, UberBlox aims to be more than just another toy-based construction set: their aim is to be an all-in-one set for today’s sophisticated maker.
Their Kickstarter is due to launch this month and you can stay updated on their campaign via their Facebook page or the UberBlox site.

Amazon is soon to be coming out with a new device called Echo, which is essentially Siri but for your home.
Amazon Echo is designed around your voice. It’s always on—just ask for information, music, news, weather, and more. Echo begins working as soon as it detects the wake word. You can pick any name as your wake word (I just want to name it TARS or Baymax now). Echo is also an expertly tuned speaker that can fill any room with immersive sound.
Tucked under Echo’s light ring is an array of seven microphones. These sensors use beam-forming technology to hear you from any direction. With enhanced noise cancellation, Echo can hear you ask a question even while it’s playing music. Echo uses on-device keyword spotting to detect the wake word. When Echo detects the wake word, it lights up and streams audio to the cloud, where we leverage the power of Amazon Web Services to recognize and respond to your request. Learn more about Echo’s voice recognition.
You can use Echo for a ton of things, just by asking including:
- News, weather, and information: Hear up-to-the-minute weather and news from a variety of sources, including local radio stations, NPR, and ESPN from TuneIn.
- Music: Listen to your Amazon Music Library, Prime Music, TuneIn, and iHeartRadio.
- Alarms, timers, and lists: Stay on time and organized with voice-controlled alarms, timers, shopping, and to-do lists.
- Questions and answers: Get information from Wikipedia, definitions, answers to common questions, and more.
- More coming soon: Echo automatically updates through the cloud with new services and features.
A pretty neat piece of tech by Amazon, which will be priced at $199 although those with Amazon Prime will be able to get it for $99.

This is just really neat and I wanted to share this cool upcoming Sega arcade game. It is called,E~deru Sunaba (translates loosely to “The Surprising Sandbox”) and through the magic of real-time projection mapping, kids can make all sorts of cool things in the sandbox.
According to kids in the video, the sand is very soft and easy to mold. However, it doesn’t stick to your hands. It looks like the game is currently in development, and it could change, but looks super neat!

Hi everyone, I just wanted to show an update of something I’ve been working on. I’ve been in the works of a board game called Heifer Heist that I am hoping to bring to Kickstarter later this summer! We just launched our new website at heiferheist.com, and we can also be found on Facebook and Twitter. If you like this game, do support us and share, like and follow and I’ll try and keep everyone updated on how when the Kickstarter will be launching and how the process is going!

I haven’t written about wallets in quite a while, but I always love a simple slim wallet designed with the minimalist in mind. The Sapling Aluminum Series wallet was designed by John McConnell. The slim design of the wallets allow you to carry it in your front pocket which makes your wallet more comfortable and secure.
The wallet features a unibody design machined from a solid block of 6061 aluminum which is an RFID blocking material.This means that your cards are more secure against card skimming, an increasingly more common method of card theft. The wallets are anodized to add a look that will hold up over time and will also allow us to add a custom name engraving with a laser engraver.
The design includes an elastic band which allows the wallet to expand to meet your needs, holding 1-8 cards.The height of the card slot is the equivalent to the width of 5 cards but because of the elastic band design, the wallet is capable of holding more and is still fully functional if you decide to add more cards.
The elastic band also stretches lengthwise across the back of the wallet allowing you to store cash or cards on the inside or outside of the wallet, much like a money clip would. The slotted design allows for fast and easy access to all of your cards.The elastic band is also conveniently placed so that the numbers on your card are concealed from view when the wallet is being removed from your pocket.
There are only a couple days left on his Kickstarter here, so support it soon if you’d like a wallet of your own!

German physicist Heinrich Rubens became a god among nerds in 1905 when he invented a tube that uses fire to visualize standing sound waves. When there is no sound fed into the tube, the flames rise to the same height. When a sound is added into the tube, the waveform actually affects the amount of gas that is fed through each hole.
At the point of maximum displacement on the wave (the anti-node), the gas pressure varies. The pressure is highest when the wave crests and the gas is pushed closer to the hole, which forces more fuel out and causes the flame to grow higher. When the wave pushes down into the trough, it can’t really suck the gas back in. The flame has enough gas and oxygen to remain burning higher until the wave crests at that point again.
The part of the wave which crosses the midline and remains unchanged is referred to as the node. This area in the Rubens tube doesn’t have the pressure fluctuation and remains relatively low.
Of course, volume plays a big role on how these flames appear. The above description applies when the volume is high, but if the incoming sound is quiet, the crest of the wave isn’t enough to overpower the opposite pressure of the trough, and the anti-nodes actually appear smaller than the nodes.
Derek Muller from Veritasium traveled to Denmark in order to check out an updated version of the Rubens tube. These physicists and chemists have developed an apparatus with 2,500 holes in the top. The key difference is that these holes are not all in a line like a traditional Rubens tube, but actually cover an entire plane.
The results are pretty amazing. Check it out:
