How a lead-acid battery works

Dan Pink on What Motivates Us

“Kinetic Rain” Singapore Airport





In the course of refurbishment works ART+COM was commissioned to create a signature art installation for the Departure-Check-in hall of Terminal 1 at Singapore Airport. “Kinetic Rain” is composed of two parts, each consisting of 608 rain droplets made of lightweight aluminum covered with copper. Suspended from thin steel ropes above the two opposing escalators, each droplet is moved precisely and seemingly floating by a computer-controlled motor hidden in the halls ceiling. The drops follow a 15-minute, computationally designed choreography where the two parts move together in unison, sometimes mirroring, sometimes complementing, and sometimes responding to each other. changiairport.com

One Hundred and Eight




One Hundred and Eight is an interactive wall-mounted Installation mainly made out of ordinary garbage bags. Controlled by a microcontroller each of them is selectively inflated and deflated in turn by two cooling fans.
Although each plastic bag is mounted stationary the sequences of inflation and deflation create the impression of lively and moving creatures which waft slowly around like a shoal. But as soon a viewer comes close it instantly reacts by drawing back and tentatively following the movements of the observer. As long as he remains in a certain area in front of the installation it dynamically reacts to the viewers motion. As soon it does no longer detect someone close it reorganizes itself after a while and gently restarts wobbling around.

Bridges by Nikhil Joshi

There is a physical world and a digital world and between, lies series of rules, interfaces and constrains. The only way to interact is to learn the rules, but why? With all these objects around us, we hold immense amount of knowledge and information about them. The way they behave and the way we handle them. But still every new digital object comes with a daunting task of understanding his way. Why can't we put our knowledge of the physical world around us, right from wearing sandals to hammering nails in the digital world to augment and alter it? The task is to create controllers whose usage is by default embedded in us. The installation "THROW" here presents one iteration of the concept of "Bridges", which aims at combining the physical and the digital world. Here we take example of a ball understanding its basic physical properties and affordances. The knowledge we hold about the ball in the manner that we bounce, throw and squeeze it. This knowledge can be mapped with quantitative values of force, spin and speed. In the installation you aim and throw the ball towards a projected stacked pile of can using your knowledge of aiming and throwing a ball right from your childhood. This knowledge of yours clubbed with quantitative values of speed, force and spin becomes an input device for the digital interface

Craft; as is established is dependent on ‘Process’ and ‘Raw-material’. Everything else is directly or indirectly its manifestation or fruition. Infact almost everything contemporary is a remote manifestation of craft and does not lead to the creation of an artefact or artwork but a ‘Product’. Every product has a defined lifespan (shelf-life), like matter itself, though the point to be considered here is that life or existence of a zillion products is not even acknowledged, not merely because of their relevance and (lack of/)usability, but because of our fast moving material economies and consumerism. These products then end up as ‘Urban-waste’, which fortunately, thanks to the development in science, has a scope of becoming new ‘Raw- material’, but unfortunately doesn’t or merely does!

Poetics of the 'unseen'


Poetics of the 'unseen' from sunil vallu on Vimeo.


Objects not only “de-materialize” into software in response to miniaturization and replacement by services, but literally dematerialize into radiation. -Hertzian Tales, Anthony Dunne
We all appreciate, enjoy and exploit the wireless technologies today we are living with, but none of us really care about what and how it does. Mobile phones, Television sets, Micro ovens and electric towers leak something that is unseen. We live in a very close proximity to these objects not because we love these objects but inevitably not being able to escape from their spectrum. We are continuously consuming these electromagnetic radiations varying from ionizing to non-ionizing frequencies without even being aware of the fact. Though there’s been a lot of studies stating these radiations are harmful for human and other beings who live in these ‘hertzian urban spaces’ and few debating against. Regardless of whether they are harmful or not, it is essential for us to be aware that we are surrounded by these waves and it is inescapable and invisible. How would it be if we could see these radio waves like we see the visible light waves from the spectrum? Would they be green, red or yellow? What would happen if we could see the information (private) that is being transferred between entities? Do they invade our body cells to reveal our personal biological information? And why are honey bees disappearing? The investigation led me to explore, exploit and understand everyday objects like Radio, Wi-Fi, Bluetooth technologies and the so called “Cultural Artifact” mobile phone.

“Just as I start to descend the staircase, it rings in my pocket. It always rings as I start to… The mobile phone universally worshipped and spared no expense.” - How are things, Roger-pol Droit

Designing for time


“There is more to life than increasing its speed”. -M.K Gandhi

Time is one of the consequences of man's eternal quest for bringing order out of chaos by nurturing his understanding of the sun and celestial bodies into forms such as sun dials, clepsydra, astrolabe, candle clocks, pendulum clocks, wrist watches and even atomic clocks. Along his path through history, 'order' took new meanings of 'improving lives' through industrialization but at the cost of mass production, massacre, democratization, efficiency and profit, but by disconnecting our values and belief.

We now live in an information age where cars, airways, emails, online shopping, instant messaging, electronic pagers and fast-food are created for his comfort. But are we really comfortable at all? Cultures and practices are lost in a mechanical world that purely values functionality and use, suffering from immense 'time poverty'. Our pace of lives drives us to ask questions such as those of our neighbour's names, or the last time we really enjoyed a meal with friends and family. Our obsession of time has turned our lives into a road-runner show, which calls for a desperate measure to take control back into the quality of our lives by slowing down and revisiting our past.

In this project, I chose to investigate this problem by developing a series of objects by tinkering and exploring new methods of communication for slowing down in a broad sense of real-world and psychological provocation using elements of irony, satire and play.

Object 2: Peep

This clock brings thought and awareness in people about their obsession of time by the simple act of tracking ones obsession. Every time a person wants to know time, they literally have to peep into the clock. Due to its hidden nature, time isn't visually available. Hence, it breaks the notion of taking time for granted. It 'attracts' attention and emotion towards the object through capacitive sensing to make time visible for the user.




Object 3: Road runner-Coffee mug

This object is a coffee mug with an inbuilt vibration system extending its connectivity through a cable to a detachable external timer. This object is designed to play a satire on the modern society and our beliefs. S/he can set their timer according to a break duration. Once the timer is set, it cannot be stopped until it activates the alarm. The alarm is triggered as a reminder when one minute still remains and alerts people with a harsh vibration reminding them about their fast paced lifestyle.



Object 4: Road runner-Lunch plate

A futuristic lunch plate with a timer and a vibration alarm system, that is embedded internally in the object. This object behaves in the similar manner as the coffee mug, but creates a larger stimuli upon the user owing to its futurisitc appearance. The intention behind the coffee mug and this lunch plate is to instigate people to re-think and strive for a better quality life by making them experience the worst kind of time poverty situations one could encounter.

Emotional Device










Pleasure to the Eyes


Supreet Kumar:

I wanted to do something with technology which is simple but pleasing to look at. At present, monsoon is going on and rain is everywhere. The situation instigated me to use an UMBRELLA which was absolutely in context to the present scenario.

I focused on the following factors-

To make the umbrella look like floating with no visible support
To make the light soothing and not harsh
To make the installation water-proof
Using PIR sensors, simple CFL light and some common sense I came up with the following result.








  • RGB LED Display, Embedded Systems and Interaction Design


    I had a course of 6 weeks - Embedded Systems and Interaction Design. In this course we were required to produce a piece of Interaction design which had some Embedded component in it.

    During this course I achieved success in doing the following tasks -

    Detection of Average colors in a static image.
    Detection of motion through a webcam.
    Detection of colours of clothes in a video through
    a webcam.
    Detection of motion in separate con ned
    boundaries, using webcam.
    Communication of Flash over Serial Port.
    Controlling of colours of RGB LED through Flash
    using Serial Port communication.

    Construct/De-Construct


    Construct/Deconstruct from Sumit Pandey on Vimeo.


    Exhibition
































    Prototyping






























    Construct/Deconstruct is an interactive installation that integrates elements of two of the most popular subcultures of the DIY (Do It Yourself) movement:
    _Handmade Craft
    _Electronic Craft
    by using handcrafted interactive furniture modules. Electronics is used to bring individuality and interactivity to the otherwise similar furniture modules and handmade furniture modules act as an interface to access the interactive behaviors. The installation lets the viewers become participants by letting them deconstruct the furniture on display and constructing furniture of their choice; in the process gaining an insight into the DIY culture.

    ShapePlay


    Interacting with Machines using Shapes
    Embedded Systems and Interaction Design



    ShapePlay Controller Prototype from Siddharth Mankad on Vimeo.






    The ShapePlay Controller is a device that is designed to control, for instance, a TV using just shapes that you draw on a touchscreen. Or even control a Radio, its tuning, volume, again using just shapes!

    This prototype has been created using the awesome Arduino micro-controller platform. Inspired by the TouchControlPanel created by Jonathan Oxer and Hugh Blemings. Based on the TouchScreen Library by David Mellis, Limor Fried and Tom Igoe.
