If you’re ever wanted to make something awesome, but thought that you just didn’t have the right tools to do so, this soda fountain by “The Wrench” could provide the needed inspiration.
The project uses an Arduino Nano to control a small air pump via a relay, which turns on when a glass is the correct dispensing position. This pushes air into a sealed soda bottle, and soda is pushed out of another tube to equalize the pressure.

Robot vision made easier Pixy2 is smaller, faster and more capable than the original Pixy. Like its predecessor, Pixy2 can learn to detect objects that you teach it, just by pressing a button. Additionally, Pixy2 has new algorithms that detect and track lines for use with line-following robots. The new algorithms can detect intersections and “road signs” as well. The road signs can tell your robot what to do, such as turn left, turn right, slow down, etc. And Pixy2 does all of this at 60 frames-per-second, so your robot can be fast, too.
Use Pixy2 for lots of different applications, find a project, or use Pixy2 for something no one has considered!
Connect directly to Arduino or Raspberry Pi
No need to futz around with tiny wires — Pixy2 comes with a special cable to plug directly into an Arduino and a USB cable to plug into a Raspberry Pi, so you can get started quickly. No Arduino or Raspberry Pi? No problem! Pixy2 has several interfaces (SPI, I2C, UART, and USB) and simple communications, so you get your chosen controller talking to Pixy2 in short order.

Bitmaps & Code by Leslie Birch Time to create two image files and convert them into a code the OLED can understand.
Use Photoshop or another imaging program to create two cameo profile pics and turn them into bitmaps (.bmp). They should be monologue and 128x64 pixels. Notice I had my images each facing another direction. Download LCD Image Converter and run.
Choose New Image and create a name. Then hit enter. Now choose Image and Import. Select the file. Now choose Options and Conversion, then Prepare. The followiing should be checked: Type: Monochrome, Threshold Dither, Main Scan Direction: Left to Right, Line Scan Direction: Forward Now select Image. Make sure Select to Rows is checked. 8-Bit and Little Endian.
Hit OK, then File, Convert. Name the file. Now do the same process for your other file. The completed files will contain a series of code that you need to cut and paste into the project code to replace the files I provided. It will look something like this, only longer. Note that you don't need the beginning name, just the brackets and what is contained within them...

Adding sounds or music to our project will always make it looks cool and sounds much more attractive. Especially if you are using an Arduino and you have lots of pins free, you can easily add sound effects to your project by just investing in an extra SD card module and a normal speaker. In this article I will show you how easy it is to Play music/add sound effects using your Arduino Board. Thanks to the Arduino community who have developed some libraries to build this in a fast and easy way. We have also used IC LM386 here for amplification and noise reduction purpose. [Gust MEES] GREAT music quality!!

Microsoft has unveiled its latest research project today, Project Zanzibar. It’s a smart mat that’s designed to blend the digital and physical worlds by sensing touch, gestures, and objects. A team of researchers, with a love of toys, created the project at Microsoft’s research labs in the UK. The mat folds and combines sensing, near field communication (NFC), and multi-touch to imagine a future where you could place objects on this smart mat and play games.
Microsoft’s video (above) demonstrates a number of different games that track the position, movement, and orientation of objects — all thanks to NFC stickers. The smart mat, that reminds me of the Surface Music Cover, can even detect inputs like button presses, and works with existing devices via Bluetooth. While the software maker demonstrates basic games for learning, programming, and augmented reality, this looks like the perfect hardware to combine the company’s Minecraft game with real-world Lego blocks. Objects can be easily tagged with NFC stickers, so you could stack them and have the mat translate that physical object into Minecraft.

Laterales Denken (vom lateinischen latus für „Seite"), umgangssprachlich auch Querdenken genannt, ist eine Denkmethode, die im Rahmen der Anwendung von Kreativitätstechniken zur Lösung von Problemen oder Ideenfindung eingesetzt werden kann.
Laterales Denken Laterales Denken (vom lateinischen latus für „Seite“), umgangssprachlich auch Querdenken genannt, ist eine Denkmethode, die im Rahmen der Anwendung von Kreativitätstechniken zur Lösung von Problemen oder Ideenfindung eingesetzt werden kann.
Der Begriff wurde 1967 von Edward de Bono eingeführt und seitdem in zahlreichen Veröffentlichungen verwendet. Gelegentlich wird in der Fachsprache auch der Begriff nichtlineares Denken gebraucht. Umgangssprachlich sagt man auch Querdenken oder um die Ecke denken. Das Antonym lautet vertikales oder lineares Denken.
Edward de Bono hat außerdem den Begriff „paralleles Denken“ geprägt, der die Fähigkeit beschreibt, in Bezug auf ein beliebiges Thema systematisch verschiedene Denk- und Wahrnehmungsperspektiven einzunehmen. Das wichtigste Beispiel für das parallele Denken sind die Denkhüte von De Bono. Sie werden inzwischen weltweit in großen Organisationen in den Bereichen Kreativität, aber auch Kommunikation und Teamentwicklung eingesetzt.
Das Konzept de Bonos unterscheidet sich nur in Nuancen von dem Joy Paul Guilfords. Dieser verwendete an Stelle von lateralem Denken den Terminus divergentes Denken bzw. anstelle von vertikalem Denken den Terminus konvergentes Denken. Aufgrund ihrer starken Ähnlichkeit werden die Begriffspaare weitestgehend synonym verwendet.[1]
Im Gegensatz zum vertikalen Denken, das Schritt für Schritt (kontinuierlich) verläuft und auf eingeübten Mustern beruht, ist das laterale Denken durch folgende Grundsätze charakterisiert:
Es wird zugelassen, dass vorliegende Informationen subjektiv bewertet und selektiv verwendet werden. Details werden nicht analytisch, sondern intuitiv erfasst.
Gedankliche Sprünge und Assoziationen werden zugelassen, nicht jedes Zwischenergebnis muss richtig sein.
Ja/Nein-Entscheidungen werden vermieden. Auch nicht durchführbare Lösungen können ein Schritt zum besseren Verständnis des Problems sein.
Konventionelle Denkmuster werden in Frage gestellt, indem z. B. bewusst nach der unwahrscheinlichsten Lösung eines Problems gesucht wird.
Ausgangssituation und Rahmenbedingungen werden nicht als unveränderlich hingenommen.

The real principle on which human life is based is organic growth and development,” Robinson said. It’s based on the need to invent your own life.” But the education system is not set up to allow for that kind of organic development, although Robinson acknowledges that many educators are doing their best to protect this form of learning. “They’re doing wonderful work because they believe in kids and the work, but they’re doing it against a headwind,” he said.
Part of the problem is the multitude of opinions and lack of clarity on exactly what it is an education should do. Debates about how to improve education will continue to rage because at a fundamental level participants don’t agree about why (or if) kids should go to school. Robinson firmly believes that creativity is a central element of what sets humans apart from other forms of life on earth and so educators’ mission should be to bring out the unique creative energy within each child.
Robinson believes education is “to enable students to understand the world around them, and the talents within them, so that they can become fulfilled individuals and active, compassionate citizens.” He doesn’t deny that learning information about the world is important, but he says it’s equally important for students to understand their own talents, motivations and passions if they are going to lead lives that satisfy them. The current system of conformity and compliance leaves no space for this type of self-exploration.

Learning to Code So, you like video games? Do you know that actual humans make video games with some type of computer code? It's true. But even better, kids can write programs too. It might seem scary to get started, but it's really not too bad. If you want to get started, I am going to recommend code.org. There are plenty of learning guides that are appropriate for a variety of ages. Oh, and it's free and online.
Even the lowest level activities are very complete—they even include ideas about functions and debugging. It's the best way to get a general idea of computer programming before moving on to a particular language.
If you want to be more creative with your programming, there is also Scratch (scratch.mit.edu). Scratch is a graphical (and free) programming language that focuses on the control of animated sprites. It's pretty easy to pick up and it's built so that you can share programs and modify others.
Finally, there is one more set of coding activities—physical programming. Physical programming takes some type of code but adds onto it some actual object that the code can control. If that sounds awesome, it's only because it is. There are two physical programming platforms that I have worked with before—Raspberry Pi and Arduino. Although these devices are not free, they aren't super expensive either. Both platforms have tons of great projects that kids (or adults) can work on.

How to connect and program the Geekcreit 0.96 inch 4 pin white I2C OLED module with Arduino. OLED display based on a SSD1306 OLED driver IC.
In this tutorial a 0.96 inch monochrome OLED display from Geekcreit is connected or interfaced to an Arduino. Libraries are then installed and some example programs run which show how to use the display in an Arduino sketch.
The display connects to Arduino using only four wires – two for power and two for data, making the wiring very simple. The data connection is I2C (I²C, IIC or Inter-Integrated Circuit). This interface is sometimes called TWI (Two Wire Interface).
At the very lowest level, the Arduino Wire library is used to communicate with the display. Libraries are available that make it easy to start using the display right away to display text and graphics. These libraries are installed in this tutorial. [Gust MEES] It works with THIS OLED <===> https://www.amazon.de/dp/B01L9GC470 Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/21st-century-learning-and-teaching/?&tag=ARDUINO

As robots take over more and more “dirty, dull, and dangerous” jobs from humans and automation assumes the knowledge work once done by people, the vocations that require complex, creative thinking will remain the domain of the living.
This point was driven home in a recent World Economic Forum (WEF) report, which forecasts expected advances in automation, artificial intelligence, and other areas that constitute Industry 4.0. The changes, already unfolding, could — and likely will — be profound, and include shifts in even the most essential job skills.
The report compares the top skills needed in 2015 and those predicted to be critical in 2020 (which is just a few heartbeats away). Quality control and active listening drop from this list — perhaps new technology will take care of these. Emotional intelligence and cognitive flexibility take their place. What I found most interesting is that creativity rockets from the number 10 spot all the way up to number three.
