Browser book-marks brought alive using RFID

A device that opens the websites using physical world interaction? This is a step closer to the internet of things. Using our beloved Arduino and RFID tags, we can think of a lot many applications of this device!

Too lazy to create your own Arduino + RFID reader? No fear! Arduino internet Gizmo is here.

A detailed Step-by-step making instruction is given here.

What websites are you going to keep as your shortcuts today?

A revisit to open frameworks

Remember this?

A good tutorial by Sparkfun will help us make the above display. Before we begin let us take a few questions on Open Frameworks.

Q> What is Open Frameworks?

openFrameworks is a very handy software library written in C++ that is written for the sole purpose of reducing the software development overhead faced by designers and artists that would like to create pieces that use various media (graphics, sound, video, electronics, etc.).

Q> Why Open Frameworks when there is Processing?

Because there are some things that oF is well suited for that Processing just can’t handle. oF is much better at creating projects that use a lot of 3D Graphics, computer vision libraries like OpenCV or projects that involve the real-time manipulation of video. Also, while Processing requires a Java backend, oF is simply a set of C++ libraries, meaning that developers comfortable with C++ will be right at home.

Q> Where can I find more data and examples on Open Frameworks?

You can start by reading this article.

Try it, it works!

MathWorks announces built-in Simulink support for Arduino

“MathWorks is the leading developer of mathematical computing software. MATLAB, the language of technical computing, is a programming environment for algorithm development, data analysis, visualization, and numeric computation. Simulink is a graphical environment for simulation and Model-Based Design of multidomain dynamic and embedded systems. ”

Now that the basics are clear, let us enjoy the beauty of the new feature!

“Simulink built-in support for hardware is a big boost to project-based learning,” said Dr. Farid Golnaraghi, professor and director of Mechatronic Systems Engineering at Simon Fraser University. “Our engineering students who learn control theory by creating and running models in Simulink can now easily test and tune their algorithms on hardware, without knowing embedded systems.”

Simulink provides built-in support for the following platforms:

Arduino Uno and Mega 2560 microcontroller boards for robotics, mechatronics, and hardware-connectivity tasks
BeagleBoard-xM single-board computers for audio, video, and digital signal processing
LEGO MINDSTORMS NXT robotics platform for robotics applications

As you know MATLAB is a product of MathWorks, and is widely used for data visualization, attaching an Arduino would be really beneficial and wonderful applications from the maker community can be expected!

New in the Maker Shed: Positive RGB LCD Display Shield

We’ve had RGB LCD displays in the Maker Shed for a while now and while they are really cool, they take up a bunch of pins on an Arduino. This new Positive RGB LCD Display Shield fixes that problem by using I2C for communication. Using I2C, what once took 9 pins now takes only 2! Since the shield uses the I2C bus, you can add other I2C sensors to the same pins driving the LCD. It’s a great way to incorporate an LCD into your Arduino projects without the messy wiring! It even includes 5 input buttons for building projects that require a user interface. Very nice!

Features:

  • Dimensions: 2.1″ x 3.2″
  • Comes with a 16×2 RGB backlight LCD, positive display
  • Plug and play with any Arduino ‘classic’ – UNO, duemilanove, diecimilla, etc as well as Arduino Mega R3.
  • Uses only the I2C pins – Analog 4 & 5 on classic Arduinos, Digital 20 and 21 on Arduino Mega R3
  • Note: The shield comes as a kit and requires soldering!

Android-Controlled LED Light Shirt

Write an Android app to control an LED light shirt. The app communicates to an ATmega128 via a BlueSMiRF Bluetooth transceiver. The microcontroller outputs data on the SPI to daisy-chained shift-register-controlled constant-current regulators driving RGB LEDs.

Drives Arround

I started this robot a couple of weeks ago, it's just plywood, plastic wheels, some hitec 615mg servos that were laying around modified for continous rotation.  Currently control is through an Arduino Uno being fed by an RC receiver.  I have a PING sensor and some IR LED's that I think might make it a bit more interesting in the near future. The code is really ugly at the moment.  I'll attach it to this post as soon as I figure out some place to stick it.

Arduino-Powered Wire Bending Machine

The DIWire Bender is a rapid prototype machine that bends metal wire to produce 2D or 3D shapes. Wire unwinds from a spool, passes through a series of wheels that straighten it, and then feeds through the bending head, which moves around in 3 dimensions to create the desired bends and curves. Vector files (e.g., Adobe Illustrator files), text files of commands (e.g., feed 50 mm, bend 90° to right…) provide DIWire’s instructions. It’s essentially a 3D printer that describes lines, instead of volumes, in space, and it could be used for anything from prototypes to customized products.

Chess sequencer

The musical interfaces can sometimes be extremely curious. That’s the case of  the chess sequencer.

 

 

The Chess Sequencer is a step matrix sequencer made from a chess board, where placing the pieces make music. The sequencer is connected to software synths on my Mac trough USB and a Processing patch to convert the serial data to internal midi.

The core here is an Arduino Mega. I was planing to use the Duemilanove but laziness caught me. The Mega has tons of IOs so I do not have to make a lot of multiplexing saving me hours of work.

Check here the full instructions to build your own!

iOS and arduino – A talk

Alasdair Allan, author of Learning iPhone Programming, Programming iPhone Sensors, and iOS Sensor Apps with Arduino, sat down with MAKE’s Dale Dougherty to talk about getting iOS devices and Arduino talking to each other.

The words of an Astrophysicist turned maker!

Hear-hear!

Heart Rate Monitor using Android and Arduino

Last week I decided to buy some stuff from local reseller of Arduino. I bought a Kyto Heart Sensor that transmits heart pulses to a receiver via radio frequency. The RF receiver can then be interfaced to an arduino and then pass the results to an Android device for visualization.
