Meet Ozobot my kids best robot friend

On my last trip to San Francisco this year I visited the California Academy of Sciences where i was immediately fascinated by a tiny robot called Ozobot. Ozobot looks amazingly cute and is able to perform a lot of magic that ultimately teaches your kids how to program by using a visual programming language thats similar to MIT Scratch. Ozobot moves along a black line and reacts on color codes that tell the bot to either turn, move faster or slower or to change the color of its led. Even if your kids are not programming so far its fun to paint mazes where the little friend moves around. Ozobot’s primary sensor is the color scanner that allows the bot to follow the black line and to read color codes in order to control its movements. Another amazing feature I found our recently is the possibility to program the little robots movements by using a visual block language called Ozobot Bit Blockly. Simply program your own Ozobot program online and transfer the program visually onto your bot without any cable involved. Its super cool to see how the bot receives its new program by just sending color codes to its scanner. Ozobot is clearly one of the most innovative teaching robots available right now, because its super simple to use and it looks so cute.

e-Ink Displays – Underestimated Technology for Rough Industrial and Outdoor Interfaces

Since the first commercial appearance of e-Ink Displays around the year 2008, a large collection of cheap e-book readers, such as the Sony PRS505 or Amazon’s Kindle, were successfully introduced on the consumer market. As the e-Ink technology became mature in this field of application, millions of e-book readers are in active use today and the amount of sold e-books is nearly the same level as of traditional books.

E-Ink technology was first mentioned in 1997 based on research started at the MIT Media Lab. Joseph Jacobson and Barrett Comiskey are listed as inventors on the original patent filed in 1996.
E-Ink displays offer some great advantages over alternative display technology, such as extremely low power usage, incredible high contrast and the ability to preserve the static image for an unlimited amount of time without the use of any energy at all. E-Ink displays on the other hand do not offer much multimedia capabilities as they are mostly operating on grayscale, or very simple single color modes. Also their slow reaction times prevent e-Ink displays to show any videos.

Beside the widespread use of e-Ink displays in e-Ink ebook (or even as prototypical Smartphone display) reading devices, their use within industrial applications and rough production or outdoor scenarios is still underestimated. As e-Ink displays offer perfect contrast and preserve the displayed image over an unlimited amount of time, these displays could be the perfect choice for machine interfaces.
Following examples show the use of e-Ink displays in various interesting applications, such as static information on pillboxes, showing information directly on a mountain bike or even to directly show information on a snowboard.

Augmented Reality Takes Off with Google Glass

Google’s Project Glass, the implementation of an augmented reality head-mounted display (HMD), has gained a lot of publicity over the last months. Recently, Google published some additional promotion videos that should demonstrate the benefit of these head-mounted transparent see through displays. Project Glass introduces the recording of personal activities in first person perspective, comarable with a helmet mounted action cam. Google Glass is also used as an unobstrusive information display, in order to give you additional background information in every situation of your daily life.

Arduino Controlled Magic Chess Board

This Arduino controlled Chess board set tangibly connects two players with each other from anywhere in the world. To combine physical interfaces to intuitively control virtual environments gives users the possibility to control all kinds of digital technology without much background knowledge. The combination of tangible artefacts with digital content is called ‘Tangible User Interfaces’. This amazing chess board game is a perfect example for such a tangible interface approach.

Plant Link – Smart Embedded Gardening for Everyone

Plant Link, recently started to fetch funding on Kickstarter tries to make your gardening a little bit smarter than usual. The inventors of Plant Link promise that by using their smart plant monitoring device even the biggest plant killers get a green thumb.
Plant Link is a hardware device that monitors the water needs of your lawn, garden, or house plants. It alerts you on your iPhone when your plants need to be watered and can even water them for you, at least for a while. Plant Link is designed for indoor as well as for outdoor use, just put it  beside a plant you would like to monitor. Plant Link is then acting as the ‘Big Brother’ for your plants as it is configured and paired exactly for one type of your plants, as each family of plants has different needs. It is even possible to log into the Blog of your plant to see if they are doing well or not. Plant Link perfectly follows the actual trend of green gardening technologies.

With Plant Link the Internet of Things is definitely growing into an Internet of Plants as well 😉

Its no surprise that the adorable lean product design of Misfit’s Shine personal activity tracker catched so much public attention that its Indiegogo pledge for funding reached nearly  $700.000 and exeeded its target value by around 600%! Misfit Shine is designed as a waterprove, durable and very light personal device that you can wear even if you go hiking or swimming. Shine is carved out of solid steel within one piece and wirelessly transmits your activity information onto your iPhone. In order to sync your devices data, just lay your Shine on your iPhone.

Misfit Shine offers a lean interaction design by just showing a circle of tiny leds that indicate your potion of activity for your day. The Misfit Shine personal activity tracking device now also is shipped in sleek matte black, which gives it an additional exclusive touch.

Lego announced next Generation Lego Mindstorms EV3

At this year CES, Lego just announced the next generation of Lego Mindstorms Educational robotic invention kits. Lego Mindstorms robotic educational kits are used by a large community of robotic hobbyists and the release of the next generation of their invention kit was a logic step. The new generation of Lego Mindstorm Kits is called Lego Mindstorms EV3 and will offer a deeper integration into the users consumer electronic, such as smartphones or digital cameras. Lego enhanced the new Lego Brick by adding more (16 MByte) Flash-Memory and (64 MByte) RAM, to offer the user more space for complex programming. In order to store sensor values or images on the Lego-Brick, Lego added a SD-Card slot. Lego also improved the 3D engineering experience by offering a new Creation software that is based upon the popular Autodesk suite, which enables the 3D engineering of Lego models and to provide a perspective view on your designs.
