Lesson 3

First of all:

Here is the download file:
http://www.contrechoc.com/crosslab/e_paper_workshop.zip

We will do a Processing session, explaining the download.
Then we will pick one/two sounds, and make a switching button like the one in the instructable:

http://www.instructables.com/id/Hack-that-holy-USB-cable/
(more than 9000 visitors in one week, wow!)

see the Heidegger switch button:

And this button will produce two sounds, one for each side...

How will the button trigger the sounds?

We use a hacked keyboard for this:

 

This was a keyboard, you can use any USB keyboard to get the chip out.....

Here you see the chip, and this can be made in a base for a button

 

We have attached already some stuff....the things are not soooooo well "designed" yet, more important is that we don't destroy the wire connections.......

technical things to consider: which keystroke is coming in? Use textdit to find out.....

then you have to replace the coded key by this new keystroke....

design things to consider:

how is the paper button related to the sound?

what is the effect of the action, (hand contribution?)

how is this related to "more than design?" (see www.designprijs.nl )

how can we influence society with our interactive device? :-)

resulting in ......

Class 2: Hack that holy USB cable!

Instructable
(featured): http://www.instructables.com/id/Hack-that-holy-USB-cable/

(Be careful, don't shortcut the USB port!)

We will work with simple cheap USB devices, vacuum cleaners, LED lights, and hack the cable to the USB.





















This cable normally has 4 wires:
GND
5 V
DATA+
DATA-

In the gadgets, there are only two wires used, the GND and 5V.

The 5 Volts form the USB is a good energy source, without bothering ever again about flat batteries!



 We can make a paper switch of button by cutting one of the wires.
The shape, the design has to fit your purpose. ANd use the LED ore fan, or motor to take part in the new gadget we make.

The only thing to watch is ....LED's are running at 2-3V so they need a resistor of 300Ohm - 1K.
Same thing with the motor running normally at 3V.

Pictures of the inside of the gadget:

Either the red or the black wire can be cut for inserting a paper button.

The motor and the LED can be used (without the casing) into your own "paper" gadget.

Class 1: a circuit with a paper button

A circuit is:
a complete and closed path around which a circulating electric current can flow.
a system of electrical conductors and components forming such a path.

http://en.wikipedia.org/wiki/LED_circuit

A LED is:

This is a LED on a coin cell battery (3V) with a perspex shap on top of it,

A drawing with a LED is:

A drawing enriched with interactivity of one or more paper switches and buttons where the LED or more than one LED dependent on these switches performs a role in the perception of this drawing. (Beam in e-paper class:-)

e-paper eindopdracht

REMAKE INTERACTIVE

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Maak een remake van een bestaand affiche (of eerder zelfontworpen affiche) en of bestaand boek (cover).

Gebruik binnen deze opdracht de nodige e-paper technieken die je de afgelopen weken hebt opgedaan.

Denk na over de toegevoegde waarde van de 'virtuele laag' en de toegevoegde waarde van interactie.

Laat je niet qua concept beperken door de techniek maar vergeet tegelijkertijd niet dat je 4 november een werkend en mooi af ding kan laten zien. Dat mooie affe ding kan ook een prototype zijn!

Kortom gebruik je tijd goed en focus je op het ontwerp en de uitvoering!

Belangrijke toetsingscriteria zijn:

- Wat is de rol van interactie in relatie tot de inhoud van het affiche of boek

- Hoe ziet het uiteindelijke ontwerp eruit; vorm/esthetiek in relatie tot het concept

- Hoe is de technische uitvoering?

De beamer

Voor de poster, maar ook voor de cover van het boek is de aangewezen techniek het projecteren van het computerbeeld (afbeelding, geluid of video) op de poster (of het boek). Dit betekent het gebruik van een beamer ipv een beeldscherm.

(Houd rekening met de afstand van de beamer tot de poster, de groote van het geprojecteerde beeld, de wijze waarop het beamerbeeld aansluit bij de poster zelf, de resolutie. Zorg voor een goede test voor afgaand aan de definitieve presentatie!)

Opmerking: er zijn geen 20 beamers, (waarschijnlijk werken we met 3 beamers tijdens de eindpresentaties) dus de beamers moeten worden gebruikt en geinstalleerd tijdens de presentaties door verschillende studenten. Probeer dus het installeren zo eenvoudig en overzichtelijk mogelijk te houden. Gebruik van eigen laptop's is aan te raden!

E-paper modern industry

What we do in the e-paper course is an introduction in a couple of weeks of low tech, do it yourself, paper interfaces to computers.

The fun is that you can do everything you want with the material "paper".

This post gives a couple of links to indicate what is done, and what will be done in the future, by more experienced and commercially driven companies and more profound research.

E-paper as an idea is for a lot of people equivalent to e-readers, so there is a lot of research to get better reading surfaces, a bit recreating the magnificent properties of paper, adding one: erasing.
The e-paper.blogspot.com site is a blog follwing these developments.

We search for interfaces which are DIY, cheap, disposable, pliable...

Then we have MIT, always looking for interesting corners of research attack:
