Useful: Adam D., Evrhet M., Mark A., and Minh T. created a Q&A service that would let users ask and answer questions about a particular business.

Funny: Need to know when we’re launching our next product or how many users have signed up today? Then look no further than the Yelp Jumbo-Tron-O-Matic courtesy of Ben B., Jon M., Eskil O., Evan K., Daniel C., and James B.

Cool: At Yelp, we don’t mess around with our beer. To make sure we never run dry or get a bad pint, the geniuses on this team — John B., Gabe H., Alex D., Julien R., and Jeff M. — built the Kegbot. Controlled by an iPad app, you can tell how much beer is being emptied (and at what rate: cough, John), as well as leave a 5 star review for your brew.

We’re very happy to announce an updated version of the Arduino Ethernet shield, with some nice new features. This revision incorporates a micro-SD card slot so you can store files to send over the network. It’s compatible with the Arduino Mega (using the SPI pins on the ICSP header). It adds a reset controller which should address the problems some people have had getting it to work directly on power-up. All-in-all, we think it’s a well-rounded upgrade to a useful product.

So you’re pretty fond of your Arduino. You make blinking lights, and beeping noises. You’ve made a robot that was pretty cool. Or maybe you didn’t. Who cares, You’re ready for the next step. You want to extend it. Although you can just plug in wires, there’s something very appealing about making a shield. Instead of a rats-nest of wires piled about and plugged into your prototyping breadboard, you can have a nice clean shield with labeled connections and a smaller footprint. So here I’m going to tell you everything you need to know to make a schematic and PCB layout, and get a beautiful shield that will plug into the top of your Arduino.

Searching on the net on Arduino and Arduino web-sites you will find a lot of projects and ideas about the use of EEProm devices as a non-volatile storage method to save data. Arduino is equipped with its own – very small – EEProm memory to save configuration parameters and much more. Arduino boards have about 32 Kb – or even less – storage area and users experience the need to expand it in an affordable and robust way.

The development of a memory bank based on I²C bus EEProm relates to the creation of some kind of software in order to offer at least the possibility to access every memory location regardless of the number and kind of physical devices actually used. Following this way, we developed this memory Bank, aka EEProm 128×8 in respect of these requirements. After having carried out tests and made changes to the first hardware prototype, we are now releasing hardware version 2.1, part of the Bank project 1.2

Laboral Centro de Arte, Spain, has commissioned the creation of a documentary about Arduino. The filmmakers are almost done with it and today they released the trailer to it. A lot of the footage was shot during the Arduino Uno meeting in March 2010, that took place at ITP, New York University.

The documentary is CC licensed, which means you guys can use it in class, public display, etc. The official release including the 45m TV version (with English and Spanish subtitles), the full interviews to all of us, videos taken at Makerbot, Adafruit, NYC Resistor, etc will be soon announced at the film’s website: arduinothedocumentary.org. If you want to volunteer making the subtitles in your own language, feel free to contact the guys behind it.

The four researchers named in the study managed to construct their hardware sensor package completely off-the-shelf, using a combination of one three-axis accelerometers, three gyroscopes, and a Bluetooth radio all wired to an open-source Arduino controller.

“Our method is completely automatic, handles per-pixel, spatially-varying blur, and out-performs the current leading image-based methods,” reads the accompanying paper.

“To the best of our knowledge, this is the first work that uses 6 [degrees-of-freedom] inertial sensors for dense, per-pixel spatially-varying image deblurring and the first work to gather dense ground-truth measurements for camera-shake blur.”

The txtBOMBER is a one-hand-guerillia-tool – a machine not much bigger than a pressing iron – that generates political statements on the fly and immidiately prints them on any flat surface.
If you feel you are part of our modern viewless generation, the txtBOMBER is the perfect tool for you! Just switch it on, it’s powered by a strong battery. And move it along a wall. It’s that easy to show your?its?someones? opinion of something?someone?! Hell! You should reconsider if you are keen enough to use it!
The txtBOMBER has seven build-in pens to “print” the letters and a micro-controller-brain (Arduino), no need for a computer or any other brain.
