fromCONCENTRATE

here is a quick summing up of my progress in developing this ‘augmented inadequacy’ device for my DOING assignment:

Progress…

1.  Arduino —> Programmable Display

I used this LCD display:
http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=45_71&products_id=151

And this tutorial helped a lot: http://www.arduinoprojects.com/node/13

Problems:

* need to make secure connection to LCD

* need to control contrast of LCD

Code already called the LiquidCrystal library at setup and interfaced seven of the arduino digital pins to the LCD:

// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(2, 3, 4, 9, 10, 11, 12);

I put the wire controlling the LCDs contrast (pin 3 on the datasheet excerpt below) into the arduino digital pin 5:

// contrast variable to digital pin 5
const int contrastPin = 5;

And then established the best contrast level for this 16×2 LCD using PWM (which runs from 0-255) via analogWrite – 118 seemed a good value:

//PWM value
analogWrite(contrastPin, 118);

* need to work with Arduino Nano

2. Programme —> allow switching of display

(Demo with tilt sensor shows principle)

3. Transmit / Receive Infra-Red Signal

bought these IR components:

sought advice here:

got stuck!

tried this instead:
http://www.instructables.com/id/How-to-make-an-arduino-IR-link/

but also does not seem to work :-(

4.  (received vibration motor – have not yet integrated into programme)

5.  Cut out a simple housing on the laser cutter to demo the concept and give an example of layout:

IR transmitter and receiver mounted above and below electronic display.  (I added a button to the bottom right which would allow the device to be triggered ‘manually’ by the wearer themselves.)*

*added later – in retrospect, the last minute addition of a ‘manual’ button, allowing the wearer to trigger the device themselves is totally unnecessary and undermines the concept of the device.

Insight into the development process for my latest DOING assignment:

This piece is part of a larger dialogue/work ‘AUGMENTED INADEQUACIES’ which you can read about here:

more soon!

The final submission for the Digital Media DOING module requires a response to the theme of “Extensions of Man” – invoking a McLuhanesque conception of communications media & technology as extensions ov our human capability.

This relates nicely to a new project I have been developing – Augmented Inadequcies – in collaboration with the artist Alan Smith and Allenheads Contemporary Arts:
