Hot ChocLED!merged


Do you always burn your tongue on a fresh brewed coffee because you’re in a hurry? Do you forget your hot drink often and experience the “special” taste of cold coffee then? The solution for this problems is called hot chocLED. Just plug hcLED to your computerUSB or to another power supply and place your drink on it. HcLED will light up. The colour shows you if your drink is cold (blue), warm (yellow) or hot (red). The heat is conducted via aluminium foil to a LM35 temperature sensor. The signal of the sensor is interpreted with an arduino that switches the light on and off concerning the actual state. The spot for placing your glas or cup is a bit soft to adapt as good as possible to the container for the best possible heat conduction. HcLED is very light, easy to use and fits in almost every modern kitchen. The USB port can be used to enhance hcLED by everybody because the hot chocLED software is open source. So stay tuned for the processing user interface or for the hcLED twitter app ;D.

Hot chocLED is the miniproject of Naghmeh, Suvash, Diogo and Alex (Group 7).


Super Mario Game-hack-ed ! by Student

This project involved hacking into a Logitech Gamepad, which would be controlling the Super Mario game character in a computer ( emulated inside a Nintendo Game Emulator ). Instead of directly using the gamepad, wearable sensors/switches were made which connected to an Arduino, which in turn then controlled the gamepad using a hack in the circuit.

We(Group 7) fabricated two bands which could be worn over elbows or knees as preferred and two switches which were intended to be place inside shoes. Bending the elbows/knees would move the Mario in either directions, while the other two buttons performed the “Fire” and “Jump” action.

Below is a video in action…

Below are few images of the sensors that were created for the prototype to work.

The AIRduino Guitar is a wearable virtual guitar controlled with your hands much like a real guitar.

It uses ultra sonic sensors to measure the distance between the hands, and an accelerometer to simulate a string.

“The Interactive Doll House”

This doll house is an interactive toy for kids, any gender, any age! The house is divided to 2 floors and 4 different rooms. Bedroom, living room, kitchen and hobby/music room. Kids can experience real life in their doll house by putting their dolls in any parts of the house. They can learn more about the real life in this way. For instance by putting the doll on the bed the curtain will drop and the light will go off. Or whenever the doll is in front of the TV, it will be on and vice versa. The same stories in the other parts of the house happens. They can listen to music as well when the doll is in the hobby room. There is a switch embeded in the bed which is connected to the servo motor ( for moving  the curtain) and turn on or off the bedroom light. In the other rooms there are IRs which can detect the doll’s presence. Totally it would be fun for children even for adults to play with a completely intelligent doll house…

Designed and implemented by Group # 8 (Physical Computing 2009) as their Mini project.

‘Huggable Lily’ is an interactive flower, made to cheer you up when you feel a little low.

The flowerpot has two temperature sensors attached to it sides which, when heated up, will start a servo motor which will push the stem of the flower upwards. Three sets of LEDs are attached to the top of the flower, which will light up, one after another, as the stem is raised.

Compose:Me is designed as a toy to help kids learn music, recognize notes and compose some simple music.


The device was designed to look like a piece of sheet music (although we did not end up drawing the lines of the staff in our prototype) where you can place magnets that function as notes.  The notes are then automatically played in a loop and can be changed in realtime.

There are eight different columns where you can place notes (magnets) and you can place either one or two notes per column.  We are working on increasing this number so that chords can be played. Currently the odd rows correspond to the notes EGBDF and the even rows correspond to FACE.  The LEDs at the top of the columns indicate which column of notes are being played. At the bottom of each column is a switch that can change the length of the note between short or long.  The overall tempo can be changed with the rightmost slider and the cycle speed of the LEDs changes to match the tempo. The device has internal speakers but can also play the music on earphones or external speakers. The volume is controlled by the leftmost slider.

After presenting this project in our Physical computing course we went to the Valand School of Fine Arts to present it at an experimental music exhibition on October 16, 2009.

We received some very positive feedback and it has encouraged us to keep on working on the device.
Our first goal in improving Compose:Me is to upgrade it so it can handle more than two tones at a time.  Other ideas we have are to create similar devices that can interact with each other and make Compose:Me communicate with a computer to be able to play more complex sound with it.
