The SMSlingshot is an autonom working device, equipped with an ultra-high frequency radio, hacked arduino board, laser and batteries. Text messages can be typed on a phone-sized wooden keypad which is integrated in the also wooden slingshot. After the message is finished, the user can aim on a media facade and send/shoot the message straight to the targeted point. It will then appear as a colored splash with the message written within. The text message will also be real-time twittered – just in case.

Building the first Open Source (inexpensive) Scanning-Tunneling Electron Microscope (STM) – With just enough electronics knowledge to be dangerous and a lot of helpful friends, I embarked on the design and build of an arduino-controlled, affordable STM with the intention of releasing the hardware design, firmware, and software via open source licensing. The goal of this project is to address the following two problems in the world of STM:Problem 1: The Scanning-Tunneling Electron Microscope, capable of resolving individual atoms, is so elegant a device that it won the 1986 Nobel Prize in physics. Despite it’s simplicity, STM microscopy can be an expensive endeavor: commercial equipment, while truly excellent, costs tens of thousands of dollars – well above the budget of hobbyists and entrepreneurs.

Problem 2: Due to Problem 1, there is a rich history of graduate students building STM devices on modest budgets. However these devices commonly require expensive external equipment (storing oscilloscopes, signal generators, commercial data capture boards, etc.). This external equipment is common in research labs, but not necessarily common to hobby and entrepreneurial workspaces. Additionally, the design information for these graduate student-built devices is spread out amongst theses and dissertations with no central repository of information; therefore, problem solving effort is often duplicated.

Sacha has worked in and around chemistry and engineering as a technician, student, researcher, hobbyist, and entrepreneur for over 14 years. He is currently the president of Pumping Station: One, Chicago’s premier hackerspace where he mostly herds cats and hackers. He also runs chemhacker.com where he discusses the intersection between science, art, opera, creativity, chemistry, and scanning-tunneling electron microscopy. He has recently spoken at Notacon 2010 and will be presenting his STM project at the Open Science Summit in Berkeley, CA July 29-31.

The Pool is an environment of giant, concentric circles created from interactive, wireless circular pads. By entering the pool, you enter a world where play and collaborative movement can create a cascading effect of swirling light and color .

Each pad in The Pool is its own wireless controller. All of the 106 pads communicate and listen to each other in an organic network formed in the same way people interact. The Pool has no single master computer and does not use a router to route or control connections. Each pad is independent, and simultaneously interacts and listens to its environment based on user feedback. Together, the 106 pads create complex, surprising, and unpredictable color arrays with their user participants.

Its been a long road. Seventeen months, countless hours, multiple dead ends, hundreds of lessons learned, and one helmet made. In the past two installments I’ve discussed sculpting, resin casting, chroming and vacuum forming. This is where the magic happens though… Illumination.

Chris briefly mentions the release of Arduino 1.0, our IDE, puts a deadline on our release (you can see he talks about September this year, even if we haven’t really announced anything … yet), and shows a blurry picture of Gianluca’s desk with some prototypes of the boards-to-be. You can take that last picture from his blog and try to zoom in it if you want to … I doubt you will see anything that will let you foresee what we have in mind right now  I guess this is just adding to the myth.

“It’s cheap and open source with lots of documentation written in a not too technical language. Above all, it has a very welcoming attitude towards beginners and tries not to scare them too much.”

Chris menciona brevemente el lanzamiento de Arduino 1.0, nuestro sistema de desarrollo (IDE), pone una fecha de entrega (habla de septiembre de este año, aunque nosotros no hemos hecho ninguna declaración al respecto … aún) y muestra una imagen borrosa de la mesa de Gianluca con algunos prototipos de las que serán nuestras nuevas placas. Podéis descargar esa imagen de la blog de Chris e intentar hacer un zoom … dudo que podáis ver algo que os permita anticipar que es lo que tenemos en mente  Involuntariamente esto sirve para crear el mito.

“Es barato y en código abierto con mucha documentación escrita de manera no técnica. Sobre todo ofrece una cara amiga a los principiantes e intenta no asustarles demasiado.”

The DollyShield is an adaptation of the Arduino Motor Shield v3 that provides directional PWM control of two DC motors, at up to 1A of current each.  In addition to the motor drivers, it also provides a stereo plug with dual opto-coupled outputs for direct camera control, a 2×16 LCD, five user input buttons, and four auxilliary inputs or outputs through two stereo jacks.  It is designed to provide an inexpensive and easy-to-use interface for two-axis motion control integrated with a camera.

In the last tutorial we used an openFrameworks application to control a process running on an Arduino board. In this tutorial we’re going to reverse that and use an Arduino board to control an openFrameworks application that’s playing back music and we’ll do it wirelessly and (relatively) inexpensively. The electronics in this tutorial are a little more involved than the previous one because we need an oF application to control and two Arduino controllers: one to send transmit data and one to receive data and communicate with the oF application. There are a whole bunch different ways to do wireless communication that we’ll outline in the section below on wireless but for this tutorial, to mitigate the cost of requiring two Arduinos, I’m going to use inexpensive Radio Frequency (RF) components to send and receive the data.

A week ago I spent a day with the Arduino team in and around Milan (production lead Gianluca Martino at left above, with raw Arduino PCBs coming off the fab). Here’s a quick report.

First, we talked a lot about the Punto Uno (“Version 1.0″) release. It’s kinda incredible that Arduino is still described as Alpha software and stuck in decimal versions after all these years. Well, no more. In September, it will finally be released in a 1.0 version.

In italian, Punto and Uno is two name of different FIAT cars  . He obviously means Uno Punto Zero, which is 1.0.

Probably you know the feeling when you get out of bed on the wrong side. The only way to avoid this is to get up at the best time of sleep rhythm. How to do that? The only way is to keep track of various parameters of sleeping human and then decide when it’s time to get up. So the following project is what it tries to do. It is based on Arduino and measures various parameters like quality of air like temperature, humidity, dew point, light level and of course tracks time along with sleep pattern.

I totally need one 

• New file extension to replace the .pde borrowed from Processing (issue #13).
• Redesigned toolbar icons (issue #291).
• Ability to upload sketches using an in-system programmer (ISP) from the IDE (issue #260).
• Simplifying the process of selecting your board and serial port (issues #223 and #257).
• Command-line compilation and uploading of sketches (issue #124).

• Creating events that can be called automatically, e.g. the serialEvent() as in Processing (issue #263).
• Adding specific functions for enabling / disabling the internal pullup resistors (issue #246).
• Modifying the behavior of print() on bytes (issue #284).
• Functions for accessing more of the low-level functionality of the hardware timers and other peripherals (issues #169 and #248).
• Optimizing the digitalWrite() function (issue #140).
