Amblone: DIY Ambilight
posted September 8 2010 3:02.51

Amblone stands for Ambilight Clone, and it is an open source 'Do It Yourself' solution for imitating Philips Ambient Lighting Technology. It projects light on the wall behind your TV or monitor in the colours that are currently on the screen. The lighting is achieved by a number of RGB LED strips that are mounted on the backside of the screen. The strips are controlled by one Arduino microcontroller, which is connected via USB to a PC. The PC captures the bitmap from the screen, calculates the average RGB values of the screen, and sends the information to the Arduino. It's also possible to select a static colour for the LED strips to output, or sweep the entire colour spectrum at an arbitrary speed.

iPhone Controlled LED Suit
posted September 1 2010 23:34.32

Marc (uiproductions) wanted something extraordinary to wear in DC 2010 festival, after heavy thinking the result was a full-body suit of LEDs that can be controled to any color or pattern desired.
Taking a white suit and sewing up to 200 RGB leds on it and having an iPhone to control via wifi the various patterns and colors did the job.
Marc also added an accelerometer and a microphone to the suit to have even more ways to control the leds.
The result is at least eye catching and sure will make his presence noticable. :)
Complete info and more videos can be found here.

Alexandre Dubus after building a fantastic tricopter, decided to keep the original chassis and add some Nintendo Wii console gyroscopes. Combined with an Arduino ProMini and a 6DOF IMU made from Nintendo Wii MotionPlus and Nunchuk.
The result is a perfect, stable flight as you can see in the video from the onboard camera that has almost no vibrations even if it is just cable staped without any vibration dampeners.
The whole documentation complete with schematics and more pics can be found here for the tricopter and here for the TriWiiCopter.

A mixed reality game using projection mapping
posted August 30 2010 17:29.58

FRAMEWORKS - A mixed reality game using projection mapping from Sures Kumar TS on Vimeo.

About a month ago we presented a Virtual Ping Pong game made by students of National Institute of Design, India.
Now the idea got further, a virtual character plays with the real space, walls and depth and can even throw a rope to climb things, all controlled by the VRglove.
The idea of mixed reality gets apart from educational boundaries and adopts a fun side also.

Build A 1W Burning Blue Laser Torch
posted August 30 2010 17:10.02

styropyro shows how to make a handheld 1W 445nm blue laser torch. The good thing is that this laser is focusable which makes it even better for burning things. According to the maker this build will cost around $130, making it cheap for what it provides:). You can watch a video with styropyro burning staff with this beast here and the video description for links to parts used and info.

Heineken Amp
posted August 6 2010 21:49.45

nikteller made a small amp (1/2 watt) and housed it in a beer can. Things are tight in there and required a smaller pair of hands (kid) to put everything in, the top had remained intact as the maker opened the can from bottom side giving it a more cleaner look. The assorted green light switch, the volume and gain knobs is the only thing you can see outside of the can and even though connected to a cheapo speaker from a clock that litlle thing has some juice in it. :)

Ball on Plate
posted August 5 2010 21:42.00

blogger45 using an Arduino,a couple of servos and a webcam made a balancing plate for a ping pong ball.
With basic control loop with discrete PID and no anti-windup he managed to have 15% overshoot and a 2% steady state error, the settling time is 2 secs on a framerate of 30fpr from camera.
You can watch more videos here.

Arduino SAFE with keyless entry
posted August 2 2010 18:07.49

Kevin Darrah build a safe to keep his valuables, but instead of using a key to unlock it he is using a wireless keypad.
The keypad, sends the code to an Arduino inside the safe wich activates a ripped car door lock mechanism to open the door.
The spring loaded door is the touch giving it a more "pro" feeling despite the fact the safe is made of plywood. :)

Test Screen
posted August 2 2010 17:57.43

Jasper van Loenen wanted to create an interface designed for a single purpose which would also show the complexity of the code involved, instead of hiding it He managed to do this by using OpenFrameworks and Arduino. Jasper wrote a script to generate a test screen, a seemingly simple thing. But the screen is made out of several objects in 3D space which all need the have exactly the right position, shape, scale and color for the script to do what is was made for.
Each one of these parameters (a total of 93) is connected to a physical switch or dail, enabling the viewer to see some of the complexity and giving him the change to change to script to his or her own liking, thus turning a normally fixed script into a design tool.
More pictures of the project can be found here.
