The Blink Box Box
Craig Hickman created this simple Arduino powered LED toy as an experiment in CNC machining. The case is made of clear plastic, which allows the viewer to marvel at his homemade Arduino board.
The LEDs change flashing patters whenever the luminosity level dips below threshold. This lets you change patterns by passing your hand over the device. It also contains a cell phone vibrator to let you know it's turned on and to give it an extra sense of presence when it's in your hand.

DIY - USB analog gauges
This is a nice write-up on interfacing analog meters via USB. The project is fairly complicated, and you have to have good soldering skills to make it all work. Don't forget, an Arduino can do this kind of thing, and it might be a little easier too!
In a sort of retro mash-up, we'll make a USB device that displays PC status info on these gauges. The gauges can show CPU and memory usage, processor voltage -- just about any numerical data typically displayed on small HD44780 based LCD character displays commonly used in PC case mods.

Ardrumo
Just when you thought the Arduino name permutations would stop - they don't!
Enter the "Ardrumo":
This is a software MIDI interface designed to accept serial data from an Arduino board and convert it into MIDI drum data in OS X. The application acts as a bridge between sensors connected to the Arduino board and applications such as GarageBand or Logic without requiring additional MIDI hardware. All data is transferred directly over the USB connection and no additional power source is needed.
Cool to see a project so fleshed out with interface software and documentation. Hit the link below for detailed info regarding piezo pad assembly as well.

HTML as sound
Ever wondered how HTML and image data would sound as beat samples?
Bill writes:
I've written a Firefox addon that makes it possible for a monome or arduino to interact with your browser. The url below is a video of me "playing" the raw data in the NYTimes homepage using a monome 40h. The project is called Lily and its a Max/PD style patching language that hooks into the browser and allows you to build multi-media projects (including physical controllers) on top of Firefox.
Each link highlighted actually makes for a nice percussive sound. This makes sense given that many percussive voices are synthesized using noise generators - and web data sounds similarly random to our ears. Awesome project, thanks Bill!

Parallel port logic analyzer
Adrian posted a step-by-step tutorial on how to build an inexpensive logic analyzer for your PC. He even has the schematics and software to download. Having an oscilloscope or simple logic analyzer can save you a lot of time when troubleshooting your electronics project.
A logic analyzer is a like a recorder for digital signals. During a certain (small) period of time, the state of a few digital lines can be recorded to a file. An event can be specified to signal the start of the recording, i.e. line 1 toggling from 0 to 1.
This looks like a really easy way to view some logic signals, but I would be a little concerned that the test probes are not isolated. You've been warned! - Link [Via]

Fritzing adds PCB design to the Arduino and Processing family
In the same style as Processing and Arduino, "Fritzing" is an open source PCB layout tool that attempts to help designers move from physical prototypes to building actual products. In particular in the area of PCB prototyping, the freely downloadable cross-platform software allows for basic layout and design of projects like Arduino shields and other projects and can also be used to document PCB designs for later publishing on the web, etc... Lots of very good introductory information at the link below.

Monomuino: an Arduino-based monome compatible
JMG writes:
I've now got my 4x4 button pad communicating with the native monome software, using the monome protocol. As far as I know, this is the first Arduino-based monome compatible, and perhaps the first third-party monome-compatible device of any kind.
Nice work! Hit the link for an in-depth explanation.

AAA powered Arduino
MAKE Flickr Pool member Funax made an Arduino-compatible board powered by a single AAA battery.
A step-up converter is used to boost the battery's 1.5V output to 5V and meet Arduino's minimum power requirements. Keep in mind - this circuit would considerably reduce current supplied to the board and therefore limit its ability to power external components.

Sonic Body
If you don't already know, I love the Arduino, and Sonic Body has a great interactive sculpture made with one of these cool little microcontrollers.
The Sonic Body is an audio-installation that uses interactive technology to create an orchestra of the human body. Developed as collaboration between four interdisciplinary artists and a heart surgeon, the installation brings together art and medical-science to reveal the unheard sounds of the body.
The video is interesting, but I am sure it is no substitute for entering the environment and seeing it in person. Unfortunately, according to the web site, it was on view at the Blank Gallery through November 2007. Let's hope it makes a trip to the US in the future. - Link [Via]

The Fluidforms Cassius punching bag
Punch out your designs with the Fluidforms Cassius punching bag sculpture maker, Arduino based too!-
The Fluidforms Punching Bag contains a matrix of 9x7 force sensors that measure the force exerted by a blow to the punching bag. The sensors are plugged into an Arduino board that sends the values over USB to a computer using the MIDI protocol. The Computer is running a Processing sketch that receives the MIDI packets and writes the current state of the sensors to a folder in a “|” separated format. An OpenGL render then reads these text files and graphically represents the current state of the punches to the bag since the last reset.The Fluidforms Cassius punching bag - Link.

Arduino to radio-control transmitter interface
Mathieu writes -
I whipped up a little interface yesterday, to connect an Arduino to a Radio Control Transmitter. This can be used to send commands from the Arduino to the transmitter, which will mix them with the manual input and radio them to the radio-controlled model.Arduino to radio-control transmitter interface - Link (and code).The Arduino is sending commands (PPM-encoded series of servo-position pulses) to the RC transmitter (a Multiplex Royal Evo 12, in this case), which mixes them with manual input and radios them to the radio-controlled model.
You can see on the transmitter's display that channels 1, 2, 4 and 5 are broadcasting values while the sticks are centered. If I had video, you could see them change over time under the Arduino's control.

uDuino: A very low cost Arduino compatible development board
Tymm writes -
Arduino boards are great for prototyping. However they get rather expensive when you have multiple concurrent projects or need lots of controller boards for a larger project. There are some great, cheaper alternatives (Boarduino, Freeduino) but the costs still add up when you need many of them.uDuino: A very low cost Arduino compatible development board - Link.This is a way, after about $25-$30 initial investment, to build sub-$10 Arduino-compatible boards with very little extra time investment on each.
Note that the basic idea here (Arduino on a breadboard) has been done for quite some time (e.g ITP Arduino Breadboard instructions); however the cable adapter build & usage instructions here help absolutely minimize the parts count for each core.
This project requires knowledge of soldering and basic electronics, and you should have at least some experience already with Arduino development. I don't suggest this as a first electronics project.
note: I pronounce uDuino "moo DWEE noh"
This Instructable is still a little under development; if you notice anything missing or have suggestions for things that should be added please let me know. I've left off some notes about potential uses/tweaks to keep the build relatively simple (I might put together another Instructable at some point based on some of the programming & testing tools I've been working on with this setup).

Making furniture interactive - The cameleon lamp
Greg's "cameleon lamp", he writes -
Concept: To design a light that mimics a color if shown to it. Design: lamp driver. LEDs are very efficient as they only emit one frequency of light, and because of this the light produced could be perceived as flat and lifeless. Instead i used tungsten bulbs because unlike LEDs they aren’t flat and lifeless. Because the Arduino cannot provide enough current to power a tungsten bulb without damaging the Arduino chip, I had to use transistors to turn a separate power source on to power the bulbs. This also meant that the lamp wouldn’t draw too much current from the laptop. To do this i connected the pwm pins to base of the transistors, and grounded the transistors to the Arduino’s ground in series with diodes to prevent current flowing back through the tungsten bulbs from the Arduino. Because i used the pwm pins i could dim the bulbs the same way one can dim LEDs in the Arduino code.colour sensor. Because I wanted the lamp to detect colors and mimic them, I prototyped a simple color sensor.Making furniture interactive - The cameleon lamp Link.

Arducopter: Arduino helicopter control
Jason @ Hackzine write -
A recent Arduino -vs- Basic Stamp discussion over on the DIY Drones site really caught my eye. Jordi makes a nice argument for the Arduino, showing off the current state of his Arducopter, which you can see in the video above. Built using a low cost electric heli, an Arduino board, and the guts from a Wii Nunchuck, his system can currently auto stabilize roll and pitch. More detail and source code are posted at the link below. It's a really great start.I've also been working on an autonomous helicopter project. While I've been able to build a general game-plan and test a few things with my BS2 controller, I know it's going to be insufficient for the device's needs.
I can say this with a bit of certainty, because I've built a GPS-guided RC car in the past using the BS2. Even with heavy optimization, I used just about all the available memory on the Basic Stamp. There's not much room to read additional accelerometer data and manage the control outputs of even a little 4 channel heli. Long story short, I've got a Boarduino in the mail.
Can a Basic Stamp manage reading and processing accelerometer, compass, and GPS data at the same time? If so, I'd love to hear it, but I'm thinking it'd be difficult to impossible. Don't get me wrong—I love my BS2. It's great for prototyping and quickly building smaller projects. Objectively, though, the Arduino is a little faster, has more ram, and costs much less.
