Automatic Harmonica
posted September 8 2010 16:42.27




toka15l is building an Arduino controlled automatic harmonica, even though the project is not completed yet and modifications needed in the programing and some noise dampening material in the motor case, if you listen close you can recognize the "Daisy Bell" tune played.
A melodic project we wait to hear it completed.

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.

Arduino Making Outbound Calls
posted September 2 2010 8:54.01





Dan Wagoner after managed to get Asterisk grab info about sensors connected to an ethernet-enabled Arduino
thought of doing the reverse thing.
Allowing Arduino to make outbound calls through the Asterisk system has many potentials like making alarm systems, doorbells or whatever your imagination comes up with.
Dan not only managed to do it as you can see in the video but he's giving all the info you want to do it yourself here.

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.

TriWiiCopter
posted August 31 2010 18:24.51





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.

Universal motor speed control by a microcontroller
posted August 31 2010 18:06.29




Ben Krasnow found a method to control speed of a universal motor (a 120V AC drill motor in this case) by using a CdS photoresistor instead of the original variable resistor used to control the standard triac dimmer circuit that was the drills trigger. The CdS photoresistor is driven by an LED that is controlled by a PWM pin from an arduino microcontroller. This system provides a very easy way to control 120V AC devices with a single PWM pin, and not use any timing code or worry about zero-crossing of the AC power since this is done intrinsically in the circuit. It also offers true electrical isolation between the AC line voltage and microcontroller.
Simplicity at its best.

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.

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. :)
