Wednesday, July 2nd, 2014

freefallcamera1

A group of skydivers and engineers, combined their passions to create the world’s first autonomous skydiving robot, equipped by a camera and controlled by Arduino Mega.

ArduinoMega Freefallcamera

The Freefall Camera is a student project at the University of Nottingham, its team is composed by David Alatorre, Tom Dryden, Tom Shorten and Peter Storey who received the third prize at the Student Venture Challenge from the Haydn Green Institute for Innovation and Entrepreneurship. (more…)

Two new little tools for your tinkering time with Arduino

Monday, June 30th, 2014

Two new Arduino products are available starting today from the Arduino Store. Read below for details!

Arduino USB Host Shield

ArduinoHostShield

This shield allows you to connect devices to your Arduino using a USB port, for example game controllers, digital cameras, phones, keyboards, etc:

- it is based on the MAX3421E, which is a USB peripheral/host controller containing the digital logic and analog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0.

- it can be used with the “USB Host Library for Arduino” hosted by Oleg Mazurov and Alexei Glushchenko from circuits@home, Kristian Lauszus and Andrew Kroll on GitHub (click to download zip).

If you want to see how to use it, take a look at this tutorial from Officine Arduino which used it to add wireless to an RC Car.

ArduinoISP

ArduinoISP

It’s a tiny AVR-ISP (in-system programmer) based on David Mellis’ project FabISP and useful to anyone needing more space on the Arduino board. Uploading a sketch with an external programmer can be used for three main reasons:

- remove the bootloader and use the extra space for your sketch

- burn the bootloader on your Arduino, so you can recover it if you accidentally corrupt the bootloader.

- when you use a new ATmega microcontroller in your Arduino, and you need the bootloader in order to upload a sketch in the usual way.

For more details about using the Arduino ISP please visit the Getting Started page

Learn how to program an ATtiny and to read your Arduino built-in EEPROM using ArduinoISP in the tutorials on Scuola.

Internet of things with Arduino Yún and Yaler

Saturday, June 28th, 2014

ArduinoYun and Yaler

Explore this tutorial  demonstrating how the Arduino Yún can be controlled from anywhere with any internet connected web browser. The solution is provided by Bo Peterson using the Yaler service which means that the Yún can be reached from any network without knowing the IP-address, and without any port forwarding on the router where the Yún is connected.

A common problem in home automation and internet of things applications is that it is difficult to reach devices connected behind wifi routers from the outside. There are different approaches to overcome this problem:

  • Port forwarding and static ip addresses. This solution requires the user of the connected device to know how to configure a router and have access to router administration which is not always possible. A Yun tutorial with port forwarding is found here.
  • Polling is a technique where the connected device at regular intervals checks with an external server if the device should take action. This solution requires no configuration of the router but it creates extra network traffic and response delays.
  • A third way is to use WebSockets which is a way of providing real time full-duplex communication over TCP. Spacebrew is a good open source toolkit for connected devices using WebSockets. Autobahn is another infrastructure that can be used.
  • Reverse HTTP is the solution that will be used in this tutorial. We will use Yaler which is an open source relay infrastructure that gives access to connected devices with very little configuration.

Soccer Penalty Kicks game with Wiring and Arduino

Thursday, June 26th, 2014

penales

It’s FIFA World Cup time and we have a project for makers who prefer to be active instead of only watching the others play. The exciting penalty shoot-out we’ve always enjoyed in video games was implemented by  as an electro-mechanical game where you save goals using a control device and kick the ball with your fingers:

An interactive coin jar saving for a good cause

Wednesday, June 25th, 2014

lightup

At the end of May, Massimo Banzi and Giorgio Olivero (Todo) spent some days at the Copenhagen Institute of Interaction Design to teach a class called Connected Objects. The class goal was to envision, design and implement interactive objects that are open and connected, whose design and behaviour can be used to sense, read and affect the domestic landscape or other shared environments.

One of the team of students (Arun Mota, Hsiang-Lin Yang, Yashodeep Gholap) worked on Arduino Yún to create an energy redistribution service that allows people to save money and in parallel donate towards energy distribution projects in deprived areas of the world:

LightUp is an interactive fundraising coin jar that firstly encourages personal savings and then also allows people to contribute a part of their savings towards the cause. The system allows them to track in real-time exactly how many units of electricity they helped generate. Another visible reward is the jar lights up for 10 minutes each time they drop a coin.

Monitoring glaciers at the Venice 14th International Architecture Exhibition

Monday, June 23rd, 2014

italian limes

Glaciers are the largest moving objects on earth and the  glacier on the Austria’s sixth highest summit called Simulaun  is the protagonist of an installation awarded a Special Mention by the Jury of the 14th International Architecture Exhibition of La Biennale di Venezia.

On May 4th, 2014, the Italian Limes team installed a network of solar-powered GPS units on the surface of the Similaun glacier, following a 1-km-long section of the border between Italy and Austria, in order to monitor the movements of the ice sheet throughout the duration of the exhibition at the Corderie dell’Arsenale.

Scan any object and instantly view the color with Nix Color Sensor

Thursday, June 19th, 2014

nix-atheart
It’s time to announce a new partner in the Arduino At Heart program!

Nix, The Diamond Standard In Color Measurement, is a unique device capable of determining the exact color of any object or surface in RGB, CMYK, HTML, Lab, and even specific paint from your favorite brand. Imagine a Photoshop eyedropper in real life: Nix is a small, durable, buttonless tool that can easily fit in your pocket or bag.

nix-sensor

It’s a useful device especially for graphic designers, interior designers, artists, photographers, hobbyists, anyone who wants to become a colour expert. It utilizes Bluetooth 4.0 technology to display the exact color on your iOS or Android device. Once scanned, you can keep palettes of your favorite colors, match the color to real life pigments, and even receive directions to the nearest store where you can purchase the color.

On top of that Nix is ultra hackable. You can easily reprogram it with all the familiar tools available in the Arduino IDE.

Take a look at their successful kickstarter campaign page and at the video below to learn more :

 

Nix Color Sensor is designed and assembled in Hamilton, Ontario, Canada by Nix Sensor Ltd and its CEO Matt Sheridan (info@nixsensor.com) is available to answer all your questions. If you want to make it yours, visit the webesite nixsensor.com .

Internet of Everything – Flip the Switch and Get Going

Tuesday, June 17th, 2014

Temboo Iot

Our friends at Temboo are releasing more cool stuff for your Internet of Everything. Here’s some news from their blog.

———————————-

Now you can connect even more Arduinos with the power of Temboo by simply flipping our IoT Mode on. This new feature opens up a whole new world of possibilities for the Internet of Things.

What is IoT mode, you ask?

It’s a new way to access our 2,000+ Choreos on any of your Arduino or Arduino-compatible boards. By just hitting a switch at the top right of any Choreo page, you “got the power” to call that Choreo with a sketch tailored specifically for the device you pick from our drop down menu. Previously, this feature was only available for the Yún, but now it is open to the larger Arduino family. All you have to do is select the type of shield your board uses and the code will generate accordingly.

So how do I begin using this amazing IoT feature?

Select a Choreo from our vast Library and turn on IoT Mode. In the example above, we chose the Data.gov API and the GetCensusIdByCoordinates Choreo. Data.gov is a cool way to access APIs from a number of US governmet agencies and to query government datasets, including the US Census! (more…)
