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.

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!

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.

A stick has been the traditional constant companion for the old people. Hence, it makes sense to hack some intelligence into it to make their life better. How about a stick that tells you when you have reached the destination? Or which tells you when to avoid an obstacle? Or better, about the various new attractions that are near the place that they are taking a walk through?

A team from Syracuse University senior, lead by Hingham resident Laura Hogan, won first place in the Senior Design Project in Electrical & Computer Engineering for designing a computerized walking stick.

Hogan and her teams’ computerized walking stick was designed to use Radio Frequency Identification tags to alert users when they have reached their destination, and also to inform them of what attractions are nearby. With the use of sensors, GU|tra will also be able to inform the user when there is an obstacle near them. The turn by turn directions along with the alerts for impending collisions will be delivered to the user using a headphone set, which will be connected to a mobile phone. The mobile phone will receive information from the sensors and RFID’s, with the help of an Arduino Microcontroller, and then announce the appropriate commands based on the information it receives. This will be done using a signal transmitted through the USB connection on the Android phone.

The next time while organizing a barcamp you can display this cool hack for two great reasons: The obvious being to look cool, the other reason being well, there is Arduino and beer involved! Where both are cool.

Aptly named KegDroid, this beautiful beer dispenser was built by a google employee, Pall Carff, uses NFC reader to identify users and dispense beer.

It’s not just the beer dispensing that sounds awesome to us, oh no. KegDroid is packed to the brim with all sorts of clever tech, mostly from Google’s labs. The giant robot has a Motorola XOOM tablet running Android 4.0 Ice Cream Sandwich jammed into its belly, which runs a custom app designed by Paul.

An NFC reader sits between the two drip-catchers and interfaces with specially made NFC tokens, sending a message to an Arduino computer board that’s inside the case, which then controls the beer pouring from the taps situated in the arms of the Android robot.

So the next step can be a humanoid beer robot fetching us beer to our table when tweeted with an @RestaurantName with #tablenumber ?

We’ve come across many an Arduino-compatible in the Maker Shed. It seems that everyday someone tells us about a smaller, newer, or differently designed version of the original.  We’re always a bit leery of selling new clones but when the Menta came around we knew it was different and had to have it (we even added it to our Mintronics line-up!) To find out why, we asked Limor Fried, the founder and engineer at Adafruit, to talk about the Menta and how it differs from other Arduino-compatabiles. Here’s what she said:

Introducing the Menta, a portable minty Arduino-compatible project that fits into a common mint tin. I’ve always like electronics in mint tins and wanted an Arduino-compatible that not only fit inside the tin but also had a built-in prototyping area like the ProtoShield I designed. We took our super popular Boarduino series, wrapped it with a prototyping area, and mounted it to a rounded PCB that slots directly into an Altoids-sized metal tin. We included everything you expect to jump-start your project; a DC power adapter with polarity protection, beefy 1 Amp 5V regulator and 250mA 3.3V regulator for 3.3V devices, green power LED, red blinky LED, standard ISP-6 reprogramming header, FTDI interface plug to connect an FTDI Friend or cable, and female headers so you can use standard Arduino-compatible shields. We also added four mounting holes so you want to attach it permanently to a box or plate, and added a massive prototyping area so you can have your finished project fit completely into a protective box.

Here are her favorite things about the Menta:

• Fits perfectly into a common mint tin – an easy-to-find and durable enclosure.
• It’s shield-compatible! You can plug in any shield with standard Arduino pinouts.
• It has a built in prototyping area for a fully enclosed project.
• The high quality, USA-made PCB is the best PCB we could get and will survive beginners, soldering and de-soldering.
• We gave it 4 massive mounting holes with no parts in the way, making it the perfect Arduino solid attachment.

The Mintronics: Menta is available exclusively in the Maker Shed until May 2nd. After that it will also be available on Adafruit.com.  Thanks Limor (and Phil!)

Drawing on the popularity of the Tiny Tank, I decided that some folks might want wheels instead. I give you, Little Wheels.

The Little Wheels Robot is a great little bot for beginners and experienced robot builders alike. Simple, well designed and cute as a button, it is just a gosh darn good little bot.

Here's an instance of NFC technology that's more exciting than yet another tap-to-pay scenario. Google employee Paul Carff combined a Motorola Xoom running ICS with an Arduino microcontroller to create KegDroid, a friendly green beer dispenser. The Xoom acts as a gatekeeper to that brewed goodness, only letting the bot dispense drinks after users swipe an authorized badge. The badge is read by an NFC scanner on the bottom of the case and is then authenticated (or rejected) by the Arduino board. Once the system grants access, users can choose from two selections on tap via a custom Android application displayed on the Xoom's screen. As Android Community points out -- and as you'll see in the video below -- the KegDroid hasn't mastered a bartender-level pour (read: there's way too much foam). Still, this is oodles cooler than your average keg, wouldn't you agree?

Lifehacker, usually known for its nice varied content which is relevant to everyday life, recently featured an article on “Top 10 Highly-Desired Skills You Can Teach Yourself“. A set of useful skills to keep you happy, creative and employed in today’s world.

We love technology, and we love it more when we can make it do pretty much whatever we want. There is almost no end to what you can hack, but getting started does require teaching yourself a few skills. Learning to build a computer is a good place to start. Soldering is especially helpful, and understanding the basics of arduino can help you build some really neat stuff. One of the best ways to get started is to pick a project and learn by doing. If you’re not sure where to start, our DIY tag page can offer a few ideas.
