I still recall the day when my friend Yossi came to school and showed off his brand new graphing calculator. I was stunned by how easy it was to plot complicated functions — meanwhile, the rest of us were still drawing them by hand on graph paper.
Today, I’m hoping to share that magical feeling with students around the world, with the introduction of graphing functionality on Google. Now you can plot mathematical functions right on the search result page. Just type in a function and you’ll see an interactive graph on the top of the search results page.
You can zoom in and out and pan across the plane to explore the function in more detail. You can also draw multiple functions by separating them with commas. This feature covers an extensive range of single variable functions including trigonometric, exponential, logarithmic and their compositions, and is available in modern browsers.
I hope students and math lovers around the world find this experience as magical as I found the graphing calculator so long ago.

The honor of having your own Google Doodle is bestowed upon only a few very special individuals like Gregor Mendel, Alexander Calder and Lucille Ball. Today’s entrant celebrates the 82nd birthday of the late Robert “Bob” Noyce, co-inventor of the microchip. After co-founding Fairchild Semiconductor and Intel, he mentored younger engineers to earn the nickname “the Mayor of Silicon Valley.” Surf on over to the Google homepage and you’ll see its logo imprinted over a microprocessor, which Bob helped to birth.

A very interesting feature of Arduino is the great avalaibility of library that make the developer work very simple and fast.Make a Web Server, a Web Client or post a Tweet haven’t difficulty. Try to do the same application with the Microchip’s Stack TCP/IP…. It’s not impossible but for beginner developpers is of course hard. With the Ethernet shield or WiFi shield you can connect your application to the internet world, get information, send email, post data…
Post data? But where? Some site host your data with graphics like the famous Pachube, I also use this service for my projects. But in some case could be useful have the data in a spreadsheet to do operations and evaluate numbers. In this post I want explain the best way to send data on Google Spreadsheet.

RS Components has released PCB Converter for SketchUp, a software tool that converts CAD files in Intermediate Data Format (IDF) to Collada format for use in SketchUp. This enables designers to use SketchUp as a 3D CAD back-end for to PCB design and brings SketchUp into the electronic product design realm. [via]

Arduino UNO + Google’s ADK tutorial @ – BricoGeek.com – [via]
[few days ago] ADK was presented on Google’s blog, a platform that enables communication between Android and Arduino. The downside was that the development kit costs around 300 €.
Today we bring you a scoop. After seeing different people online who managed to run the ADK on Arduino with a USB Host Shield controlling a servo or LED, we intend to play all the devices included in the kit but in our BricoGeek DIY version, with the products we have available in the store.

Google’s open accessory development kit on standard Arduino hardware, not confirmed but seems like it should work… [via]
A lot of people have been put off by the price of the reference hardware kit, which is roughly $390. What’s worse, they appear to be sold out until end of May, and Microchip’s cheaper ($80) alternative doesn’t arrive until July. So instead of waiting I decided to write a guide on how to get an ADK-capable Arduino for about $55.
Since the ADK reference design is based on Arduino and Oleg Mazurov’s excellent USB host shield, it stands to reason that we should be able to build our own hardware kit from these components. I already had these parts lying around from my work on MicroBridge, so I decided to ‘port’ their code, which in reality means just changing a couple of pin definitions.

Google picks Arduino for Android Open Accessory “kit”… [via]
From the beginning, Android was designed to extend beyond the mobile phone. With that in mind, we’ve developed Android Open Accessory to help developers start building new hardware accessories that will work across all Android devices. We previewed an initiative called Android@Home, which allows Android apps to discover, connect and communicate with appliances and devices in your home. We also showed a preview of Project Tungsten, an Android device for Music Beta to give you more control over music playback within the Android@Home network.
A USB micro-controller board that is based on the Arduino Mega2560 and Circuits@Home USB Host Shield designs (now referred to as the ADK board), which you will later implement as an Android USB accessory. The ADK board provides input and output pins that you can implement through the use of attachments called “shields.” Custom firmware, written in C++, is installed on the board to define the board’s functionality and interaction with the attached shield and Android-powered device. The hardware design files for the board are located in hardware/ directory.
