Arduino and a tri-axis accelerometer
If there was only a write-up or source code available for this really interesting Arduino project. The only details are that it uses OpenGL and a KXPS5 Accelerometer. This looks like it could be adapted into a really fun game with just a little more code.

Peggy 2.0 released
Our pals over at Evil Mad Scientist Laboratories have released version 2.0 of their awesome Peggy LED pegboard display kit. I had the pleasure of seeing this thing in action at last week's Maker Faire. I want.
...Peggy 2.0 still does the same darn thing: it provides efficient power to a 25 x 25 array of LED locations. Peggy is designed to takes some of the sting, complexity, and mess out of playing with LEDs. It's a versatile and powerful light-emitting pegboard that lets you efficiently drive hundreds of LEDs in whatever configuration you like, without so much as calculating a single load resistor. You can install anywhere from one to 625 LEDs, and Peggy will light them up for you ... The biggest change is that the Peggy 2.0 hardware now supports simple animation capability with individually addressable LED locations. Besides the microcontroller, there are now four support chips that help to drive the rows and columns of the display. Now, we're not talking live video feeds or long movies here (speed and memory considerations will spoil that party), but you might be surprised how much you can do with a little AVR microcontroller.

Controlling a speech IC via Arduino
This project uses a chip that was common in video games of the 1980's. I really like the sounds it produces. Unfortunately there isn't any how-to, or schematics, for this project.
This video shows a hardware ("real") SP0256 IC sequencer from Ableton Live via internal MIDI routing and a serial connection over USB.

The Arduino Flush-O-Matic
I am not really sure why the toilet should be connected to an Arduino, but apparently Mau has a legitimate reason. I like the mechanics of this project, and it just goes to show you that anything can be, and will be, computer controlled eventually. Thanks Mau!

Arduino beer brewing
Yuri at homebrewtalk made this elaborate setup for brewing his own beer using an arduino board and some custom java software, which he uses for temperature control heating of his mash with steam. Lots of videos of the mash prep and setup, and not too much arduino code, via Hack-a-day.

Little Helper proximity sounder
Little Helpers incorporate an ultrasonic sensor and a motor with Arduino resulting in a simple way to make environments more interactive -
Bodies moving through a space trigger motors, sounding whatever object they are attached to. Movements acquire a resonant trace. The use of movement as a trigger is intended to initiate performative engagement, drawing passersby into interactive exchange and making audible the impact of their movements upon their immediate surroundings.Check out the project page for video and source code - Little Helpers

Arduino basics - solar panel
Another quick & easy option for those getting started with the popular micro - Little-Scale posted a quick rundown on using a solar cell for Arduino sensory applications.
- Connecting a solar panel to Arduino
- The solar panel used in this example was rated at 2V and 25mA.
- Do not use a solar panel rated in excess of 5V. Doing so may damage the Arduino
- If data values appear incorrect, try scaling the byte 'data' in the Arduino sketch as it is captured.
- The analog inputs read data at 10 bit. However, a single, serially-printed value can only hold 8 bits of information.
- The data range with this particular solar panel is 0 < 6 using power-efficient, indoor lighting at night

Urban soundscapes by altitude
Chrisi writes in -
The idea is to experience urban sounds at various heights in a variety of cities. As feet are detected on a step, the experience changes to simulate an increase in altitude. A pair of surround sound headphones, some proximity sensors, leds and Arduino make everything work.Being able to vary your relative altitude sounds interesting, an option not readily available in urban life. The projects site explains a bit more -
The installation „KlangStufen" deals with the sound of cities. Every city has its quite own sound which gives us a lot of information about its character. However, we mostly notice the sound only unconsciously. The visual dominates. We can capture the complexity of the space by hearing, but we see only one part of it.- KlangStufen urban sound experience„KlangStufen" is an experiment to show, how much information you can get from the sound of a city. You can experience the urban space auditivly by mounting the different height levels of a city, which would not be possible in the real space at all. You should concentrate completely on the sounds, the visual remains in the background.

Audio ping pong
Mike made an audio-only version of pong - looks like a lot of potential fun!
When you put on the headphones, you hear a sound that is cycling through a sequence indicating its approach. The sound is somewhere on the left-right axis in the headphones. If the sound is to your left, you have to tilt your head to the left until the sound is centered. If you tilt your head (the paddle) to the right position in time, you hit the ball an continue, the ball’s approach speeding up each time. If you fail to hit the ball a buzzer and light go off to punish you and the game is over.Warning: playing audio ping pong in public while using a bluetooth headset will most likely make you appear quite insane - awesome. Audio Ping PongI am interested in using senses differently and getting people to focus on their senses in novel, interesting and engaging ways.
My first implementation is very rudimentary. My sound generation capabilities are limited to square waves at full volume so there isn’t true panning - just left, right and centered. In addition to real panning, I would like volume control to indicate the ball’s approach rather than the tone sequence I have now. I need to figure out what kind of RC circuit would smooth the PWM output to act like volume control, or use a digital potentiometer.

HOW TO - Detect pollutants with Arduino
Here's a how-to regarding the detection of volatile organic compounds using Arduino and a TGS2620 sensor -
This lets your Arduino smell (and hence you program responses to) overall gas levels for a variety of nasties, including ethanol, methane, formaldehyde, and a bunch of other volatile organic compounds.No explanation as to how refraining from shirt usage enhances this process, but we'll keep you posted. - How to smell pollutants instructable

LilyPad Arduino Embroidery
I just finished my first composition with the LilyPad Arduino, in the form of a conductive blinky embroidered wall hanging. It generates a little tune that's changeable by covering the photoresistor. If you're around Phoenix, you can come see it on Friday night at Cartel Coffee Lab in Tempe.

Robot avoids walls, needs to cut the caffeine
This project was a challenge to create a wall avoiding rolling robot called "Walbot". The bot uses an Arduino and is very effective at avoiding obstacles, almost giving it a neurotic personality. Check out the video for details and follow the how-to link below.

Arduino flash trigger
A user on the Arduino forums built this high-speed photo flash trigger -
I used Arduino to build a trigger for my camera's flash. It turned out to work really well! The write up includes an explanation of how camera triggers work and the benefits of using Arduino. One benefit of using a microcontroller like Arduino is that it's easy to have multiple sensors and then have intelligent triggering algorithms.See the code & more info/pics -Triggering a camera's flash with sound and light

Arduino in an Altoids tin
TriggerDog has been doing the projects in Making Things Talk, and came up with a great way to take the Arduino on the go:
Small easy, and awfully unorigional. But, useful and free. Now I can bring my arduino with me in my laptop bag and goof around with it at lunch time at work or wherever. I am thinking I would put a breadboard in another tin of some sort and put a battery pack inside to run any projects I might feel inclined to proto.

The Aura Cabinet
Silke sent in the "Aura Cabinet" which utilizes an Arduino to project images onto fog, creating an aura-type image. It look really interesting, and there is a video available here, but be warned, the video has a horrible high-pitched tone throughout.
By means of Processing the visitor is tracked by camera. His picture is compared with an reference picture of the background. The colour differences will be reported in a kind of silhouette. Depending on how near the visitor steps to the glass cabinet, within a certain tact recurrently new pictures are generated and illustrated. These new pictures are assimilated to a small collection of pictures while older pictures are replaced by them.

Arduino MIDI touchpad
From the MAKE Flickr photo pool
Ludo_d built a custom MIDI touchpad controller using Arduino -
Started from a scavenged Cirque Glidepoint resistive touchpad (PS/2 compatible), 2x8 LCD (in 4 bit mode), two buttons and a serial Arduino board.- TouchPad Midi in use
The buttons when pressed allow to set the Continuous Controller number by gliding the finger on the touchpad. Left for CC# linked to X and right for Y.
The LCD displays the value sent in MIDI. Some custom characters where coded into the CGRAM in order to have a sort of bar graph. The first line is for X and the second for Y.

More demanding plants: "Florakel"
It seems like plants may be the next "robots" when it comes to taking over our world. We saw the Twitter Plant in a previous post. This version is a bit simpler, but it gets some of the same information across to the owner. By using a series of RGB LED's, the plant can tell you if it is thirsty, too hot or not getting enough sun. It looks like it is all powered by our favorite little micro-controller, the Arduino.
