Experiment 2: Cuppa-Tea


  • Project Description:

It is impossible to be Iranian and not drink at least 3-4 cups of tea during the day. I am not an exception to this rule, but I usually forget that I ever poured myself one. My mug, full of hot tea, will stay on the desk on its coaster until it’s cold as a milkshake. And nothing tastes worse than cold tea!

In this project, I thought maybe I could make myself something to help me remember to drink my tea before it gets cold. This object will be put next to my coaster with its lights turned off. The arduino’s heat sensor, which is very close to the coaster, is constantly checking the temperature and when it rises up to 30 degrees, it means that a hot glass (of tea, coffee, etc.) is there. Then the lights turn on. After ten minutes, the lights will start flashing, meaning it is time to drink. And they keep flashing until the temperature goes back to normal, which means I have started drinking. Then they turn off again. When the temperature goes back to normal and the lights turn off, the heat sensor will again start checking the temperature until it rises up to 30 degrees or more, and so on.

I really enjoyed making this object and will improve it for sure. my next steps would be finding more sustainable material to work with, and to work on the overall structure of the object.

  • Calm Technology Principles I am engaging with:
  1. Technology can communicate, but doesn’t need to speak:

The method of communication in this object is only through sight. The three states of lights (off, on, blinking) can clearly deliver the meaning, without attracting any other senses. “Lights off” normally means nothing is happening, “red lights on” means something is hot and should not be touched. And blinking lights call for attention, which in this case doesn’t need to be defined.

  1. Technology should require the smallest possible amount of attention:

This work will not call for attention until it is time. “Red lights on” is a state that informs, but doesn’t distract. The blinking light is also a very soft change of state, making sure not to irritate the user if they are focusing on something.

LuminArt: light up your art


by Nooshin Mohtashami


LuminArt is a simple installation that consists of a painted canvas, a series of LEDs installed (and integrated) on the canvas, one light sensor and one microcontroller (Arduino BLE 33 Sense) with a built-in microphone to monitor the sounds around the canvas.

The canvas is activated when the room its in is dark (or the light sensor is covered). Once the canvas is activated (or is ON), the microphone of the microcontroller monitors for the sounds around the canvas and randomly lights up the LEDs on the canvas illuminating the different areas of the art.

The colours of the LEDs in each section of the canvas match the colour of the art where they are placed so when the LEDs are OFF, they blend in with the art and the canvas looks more or less like a regular painting.

Calm Technology Principles

This was created with minimum amount of technology to solve the problem of illuminating the canvas in the dark (Calm Technology Principle VII). It also requires minimal attention from the user for it to be activated (Calm Technology Principle I), if the room is dark and the user talks, sings or plays music or even if there are general sounds in the room, the technology starts turning on/off the lights, otherwise, it remains as a passive painting and disappears in the background, following social norms of being a painting (Calm Technology Principle VIII).

Experiment 2: George, the Zombie Lamb (Halloween)

It’s getting closer to the Halloween, so I decide to start the project named George the Zombie Lamb. In general, there is one input and two outputs in the project. The input is the motion sensor, and the outputs are LED and servo. When the motion sensor detects movement, the servo gets to work and the LED automatically turns on. And it looks like a lamb turns his head around.

This project uses one principle of Calm Technology:

Technology should make use of the peripheral: the toy is easy to play with, and users do not need to waste energy on figuring out how does the toy work. And what they need to do is to put their fingers before the motion sensor, and correpondinly, the toy moves.
