OH_OH ROBOT, LOW COST, EASY TO REPLICATE ROBOT FOR KIDS
– July 14th, 2010
Oh_Oh robot, low cost, easy to replicate robot for Mexico DF. Commisioned by http://ccemx.org, and with the invaluable help from Gianluca Martino from Arduino.cc
I am amazed by the work David Cuartielles in collaboration with Xun Yang, Tlacotalpan, Alejandro Jimenez, Hugo and our common friend Gianluca Martino, the Hardware responsible for Arduino. The point is making a robot easy to build / repair / reproduce, low cost. Easy to be programmed by kids. As you can read, David is often involved in kid-related workshop in Mexico, and here and there in Europe. It seems that he’s achieved a good point in developing a strong yet cheap platform who is changing very quickly. Stay tuned & follow the visual diary of the prototypes at this gallery and some videos at this channel
Oh_Oh is the result of an exploration in the possibilities of cheap educational electronics. It is very important to keep the importance of low cost as a fundamental part of the project, since that will influence its design, as well as its accessibility.We created Oh_Oh after a couple of basic workshops in electronics with Kids at FARO de Oriente in Mexico DF. Very early in the process we realized there was an interest in learning about robotics. The Computer Clubhouse counts with a couple of Lego kits, but not enough for a group of 20 kids.We realized that Mexico has a couple of companies dedicated to designing, manufacturing and selling small robots. However they were not really complying with the idea of reprogramability and reusability of general electronics, due to a closed firmware and the lack of an IDE to easily reconfigure the robot’s behavior.The important aspect for us was that we could get access to all the parts needed to build a cheap robot on-site. And that we could then easily hook up this robot to Arduino and build from there. So we decided to go on with the idea of making our own robot with as little parts as possible.

WIIMOTE LIGHT-FOLLOWER WITH SERVO
– July 13th, 2010
Everybody is familiar with the infamous Wiimote. When I look at it, I think about all the useful sensors/gadgets that this little 40$ package (new) comes with. Recently I’ve been playing with the IR Camera (It’s really just a light sensing camera with an IR Filter).This particular camera is a standalone module that outputs coordinates of the 4 brightest “images”, all via I2C communication.

TELNET SERVER FOR ARDUINO
– July 9th, 2010
Nice contribution from forum user Steve Lentz
Here’s something that might help someone out there. There are plenty of examples of web servers and even a few web services interfaces, but few if any command line interfaces. A few old forum posts seem to be looking for this, but I haven’t found any good examples. This sketch allows you to read all digital and analog pins, set digital outputs high or low, set PWM outputs and change the mode of digital pins. This could be useful when debugging hardware or perhaps you just have a hankering for good old text based interaction. I’ve keep the command structure very simple, for example analogRead is abbreviated as ar, in an effort to keep the sketch size small and so the code will run reasonably fast. There’s built in help, so once the sketch is running you can ask it to give you a complete list of supported commands. Please post comments here if you find this useful (or not) or have any other suggestions.

WHY ARDUINO IS A HIT? (COMPARING TO OTHERS…)
– July 9th, 2010
have a look at this very interesting article on wired online talking and compairing Beagleboard to the Arduino success:
For electronics hobbyists, the open source chipset BeagleBoard that packs as much punch as a smartphone processor might seem like the key to paradise.Yet it is the relatively underpowered 8-bit microcontroller Arduino that has captured the attention of DIYers.Arduino began as a project in Italy in 2005 and since then has turned into an open source hardware movement. There are thousands of Arduino projects today such as electric meters, guitar amplifiers and Arduino-based gadgets that can tell you when your plants need water.The Arduino community is at least 100,000 users strong. But it is not alone.Other open source projects like the BeagleBoard, which is shepherded by Texas Instruments, are trying to win Arduino fans over.

ROBOTS ROBOTS ROBOTS
– July 7th, 2010
Back in 2007 I had the chance to make a series of lectures with Casey Reas on the topic of open tools for design and art production. We toured 6 schools within the University of California in just 3 days. I prepared two lectures for this, the first one was called “High is Five” and the second “I hate robots”. The earlier was an attempt to explain my views on open hardware, while the second was just a collection of projects that had to do with electronics and were not robots.
Time has passed and now I am experiencing a counter-reaction. Since a month ago I am designing a low cost robot for the Spanish cultural centre in Mexico (more to come on this topic). But also I am starting to meet more and more people that see robots as a way of bringing kids into understanding electronics, as well as other science related topics. One of those is Eduardo Gallego, who runs the Complubot robotics studio in Madrid, Spain. He works with youngsters and has a pretty long history in the field of educational robots.
Among his achievements, his team has won for the third year in a row the Robot Soccer World Cup (at least one of the categories). Last time was in Singapore a couple of days ago. He has made a migration from other more expensive and hard to use tools, to run all the four competing robots using Arduino boards. He runs workshops for people interested in electronics and robotics and has made Arduino into his main tool for teaching. Check hiseducational robot here.
I must confess I had no idea about many of these things until I heard about the Robot Soccer World Cup. I am still not interested either in Soccer, nor Robots (or not industrial robots). But I see the potential of robotics in the same way Eduardo does. I believe there is a lot to do and getting things cheap is probably among the most important ones.
In the next two weeks, you can attend to one of Eduardo’s workshops in Madrid, or to my workshop in México, as long as you are not over 18 
FIRST ARDUINO BARCAMP IN SPAIN
– July 7th, 2010
The Spanish Arduino community gathered on July 2nd at Medialab Prado in Madrid to share experiences. This first event was streamed live over the internet and was the chance for many of us to present what we are currently working with. You can take a look at the entry on Arduino’s Playground that documents the event, as well as watch the almost 1 1/2 hour long video that came out from the event (it’s in Spanish though).
I think we -the Spanish speaking community members- should all thankcoleoptero (that’s his user name in the forum) for arranging the event. He had so much to do he didn’t even get the chance to present his own work. According to the Spanish email list, there is a possibility the next Arduino Barcamp will take place in Murcia. This would be a great chance to talk Arduino on the beach!
From the Arduino team we are happy to see how the community continues building new mechanisms for meeting and sharing. Let us know how we can support you with our servers, video/picture publishing accounts, etc.
HOW TO RECOGNIZE OFFICIAL ARDUINO BOARDS.
– July 6th, 2010
Arduino is an open-source project and we’re happy that so many people have created variations on our hardware and software. We realize, however, that it’s sometimes hard to tell which products are part of the Arduino platform itself. The official boards are listed on the hardware page (and pictured above, with the exception of the official shields and Mini-USB adaptor). These are the products that we feel provide the best overall experience and utility to the Arduino community. They include boards from three manufacturers: SmartProjects (in Italy), SparkFun, and Gravitech (both in the US). These companies pay a licensing fee in exchange for support for these products in the Arduino software and documentation.
The official Arduino products are the only ones licensed to use the word “Arduino” in their name. Other products may be labelled as “Arduino-compatible” or “for Arduino”, but these are not a part of the platform itself and don’t fund continuing work on the project. If you’re making a product and wondering what to call it, we’ve added some guidelines to the FAQ. We think that these conventions make it easier for everyone to understand what products they’re buying and who supports them.
Finally, we’d like to thank a few companies that have been particularly good about working with us on these issues: Adafruit Industries, Oomlout, andSparkFun Electronics. Thanks for your cooperation and all the great products!
ARDUINO ROCKET LAUNCHER
– July 6th, 2010
A little arduino circuit was create to ignite the rocket motors at the recent (potentially annual) NortHACKton rocketry day.
Feeling the need to create something needlessly complicated to short a battery across the ignitor of the chemical rocket motor I turned to my Arduino Mega.I already have a dot matrix display for my Arduino and have been using it to scroll the word ‘NortHACKTon’ when we go to the NortHACKton pub meets so that those people looking for geeks in a pub know who we are ”(cos we would’t stand out enough without it )”. I figured the dot matrix could be used to provide a visual countdown and the Arduino could activate a relay which connects the 9V supply directly to the rocket and then whoosh off it goes.

HACK IN THE BOX – AMSTERDAM
– July 6th, 2010
Every morning I revise the logs for what is happening at our servers, this helps me understanding which are the trends with Arduino, which are the countries generating the most traffic, or if got slashdotted. Today I manage to extract from the list that there was a hige amount of data being transferred in one single date to just one IP number back in the Netherlands.
When this happens, I usually make some further research, because I want to understand whether this was an attack or not. If it had been an attack, I would have shut down that IP number/range to avoid problems like we had in the past when our server wash actually forced to timeout up to 50% of the requests due to netbots trying to download our programs constantly.
However, this morning, there were no signs of attack, instead I found out some traces of an article that was linking to our website at a Dutch server. This is a very similar effect to the so-called Slashdot-effect. As most of you know, Slashdot is an online forum for community generated technews (or news that are interesting to tech dudes). The attention that website attracts is so huge, that in case an article makes it to their portal, the website being mentioned there will suffer the sweet death of the fame. You will get so much traffic, that your server will think it was a DoS attack and your sysadmin will probably shut you down -just like I do with the Arduino.cc website- temporarily.
Turns out, in this case, on July 4th, took place the Hack In The Box 2010conference in Amsterdam. Niels Teusink talked about: Hacking wireless presenters with and Arduino and Metaspoilt. If you go check his article you will see how he carefully reversed engineered a logitech presentation device:
[...] abuse vulnerabilities in the product to get a Metasploit payload on to the PC of someone using a wireless presenter, by just sending keystrokes to it. This article describes how I did it and why you may be at risk if you use any wireless input device (such as a wireless mouse) [...][...] someone in the audience [could] send a ‘next slide’ command to the dongle in order to go to the next slide before I wanted to do so? Or worse: could he send random keystrokes to my laptop (after all, the device is a keyboard!). Wouldn’t it be fun if you could make a random message appear on Steve Jobs’ (or Steve Ballmer’s) screen when he’s giving his latest keynote? Needless to say doing so may be a criminal offence in your country.
Everything you need is an Arduino board (here the link that generated so much traffic to our website) and a 30Eur wireless module. The article describes in a very nice way how to reverse engineer one of this weireless presenters step by step. It is very informative and will open the door to some other Arduino-related hacking around there.
You could visit the author’s website here, and download his slideshow here.
Also at that conference Arduino interested people created an Arduino Village, yet another reason to get this many page requests in such a short time:
HITBSecConf2010 – Amsterdam will also feature a two-man team based Capture The Flag Live Hacking competition, an Arduino Village, a Hackerspaces Village (with participation from spaces in Utrecht, Den Haag, Brussels, Paris, Vienna and our very own Hackerspace Kuala Lumpur in Malaysia!) In addition to the above, members from TOOOL.nl will be on hand conducting a lock picking village and a hands on lock picking lab as well.
PANOBOTER – 2 SERVOS, MORE THAN 1300 LINES OF CODE
– July 5th, 2010
Arduino forum [mhemhe] shared on [OpenRise.com] a very peculiar creation: the Panoboter,
a lightwight robot for spheric and multirow panorama for a dslr camera. I’m using one arduino mini pro as main controller and for controlling and drive the servo a pololu servo controller.
Congratulation for the work and effort, and sucha good detailed internet page to take not of it!
