PURE DYNE

pure dyne

rob canning

• disable screen-saver and power-saving, so that the invigilation can be done remotely… the person just needs to hit one button
• re Open Source: use discourse forums for help with questions

• Imagemagick – good for stop motion
• gphoto2 – takes pic then uploads to pc via typing but if you add Arduino with motion detector you don’t have to type
• giss.tv – live stream performance elsewhere free
• Linux – free operating system

• OpenOffice.org – download to Mac!
• Firefox = better than IE
• GIMP.org – like Photoshop
  http//:meetthegimp.org = free video tutorials for GIMP
• INKSCAPE.org – like Illustrator

• SCRIBUS.net – like InDesign
• Cinelerra – simple Final Cut Pro
• also, universal batch render over network or keyframe edits for selective colour changes etc.
• Avidemux – change .mov etc files to any other video format e.g. Theora (patent-free video), but if you are going from an .flv file to a .mov file, you should start by going to a .dv file. Otherwise try .avi.

• GEM – interactivity e.g. voice-tone changes layer opacity etc
• F spot – good for organising photos
• Misfit – lightweight version of Blender
• Hugin – panorama creator software

• Kdenlive – video
• Kino – capture from video camera
• Programming: PD is the free and improved version of Max MSP. Can work with Jack or Arduino for motion detectors, motors etc.
• Command Line – for remote access to gallery installations e.g. volume etc

• Audacity – normalise is better than amplify
• Ardour – bigger than Audacity
• http://www.zotero.org – software which works as a free plug-in on OpenOffice to correctly show citations!
• .wav files are v.g. for power e.g. good sound off weak computer

• Pure Dyne upload: pc – use USB but before Windows comes up hit Esc or F2 or F12 to access Set up. Make USB head of Boot priority. For Macs, run Pure Dyne off the CD. After the boom noise, hold down letter C.

Notes from Greenberg, I. Processing:

• float = function call
• array = holds set of values
• variable – holds one value
• function = block of reusable code
• class = code structure
• statement = command
• function calls:
  size(x, x);
  background(x); // 0 = black
  noStroke();
  fill(x, x, x);
  ellipse(x, x, x, x);
  print(“whatever”);
  println(“whatever”); //inc return
  random()

• loops:
  while loop
  for loop

• Grammar:
  conditional if…else statement
  hit space bar twice = indent code
  arguments

• Identifiers
  string – myBall
  int – ballCount
  float – theBallSpeed
  boolean – variableNameAsLongAsYouLike

• Operators: +, -, *, / = +, -, x, divide
• Relational Operators: >, <
• >= greater than or =
• <= = less than or =
• == = =
• != = not =
• ++ = +1

• //interaction is concerned with a) event detection, and b) event handling
• //Add file function imports media
• //use mouse code for interaction:
• //try negative padding (overlap?)

• ellipse(mouseX, mouseY, radiusX, radiusY);
• rect(mouseX, mouseY, random(sizeMax), random(sizeMax));
• void mousePressed(){
• void mouseMoved(){
• void mouseDragged(){

• – code a draw function –
• /* draw function required when including mousePressed function*/

PROCESSING WITH ARDUINO

webcam for Face Detection? (open cv?) –

• int = movie?
• examples – basics – objects – objects, nice interactive motion / feel
• examples – basics – structure – create graphics, addictive game
• examples – basics – math?- random, nice sticks image

• examples – basics – math – sine wave, use fish instead of circles
• examples – basics – math – composite objects, funky 60s-ish eggs
• examples – basics – math – increment decrement, might be usable with train footage and train stop motion
• examples – basics – math- distance 2D, addictive game with nice circle pattern on cursor

PURE DATA

• type pd into box – new window = sub patch
• instead of using recorded sounds pd generates sounds (but can accommodate recorded sounds also)
• lists are useful e.g. substitute elements
• type print into box and join = debugging

• infrared light or proximity sensor can trigger sound
• floss manual – simple synthesiser – all the way through the whole manual via next links, includes related sites e.g. tutorials, glossary and help

• signals…
• sharing licence = we can use any code
• obiwannabe.co.uk – uses physical objects
• audio engine

• ~ = audio in code
• if GEM is rendering complex graphics too slowly it might not achieve frame rate, e.g. the image will cancel and move on
• GEM works with image / movies / live video
• source for image = png or jpeg

• source for film = .avi, .mov. .mpg
• can play backwards!
• video grabs live input of camera attached to pc / Mac = can recieve signal
• related – pix multi image: load several images and use right inlet to switch between them. [sig2pixw] = feed audio signal to image buffer

• http://gem.iem.at/ or go straight from pure data link
• GEM mini-video mixer
• add web cam: type pix_video and pix_texture into boxes
• type pix_record into box… animations of still png images including transparency

• pix_movement – animation?
• pix_background
• pix_blob – needs another object to use with sensory information
• stream mp3 to PD: diagram showing monitor – mp3 – 3 X monitors

• 15 fps = minimum logical frame rate
• go to help for examples

• Tools/board/
• File… examples… code examples e.g. blink
• code: ls = list, int = number

• language is called Wiring
• variables are good because you change only in one place and it is global e.g. int delayamount = 5000
• delay(delayamount)
• serial = transmit & receive character = letter

• string = word/sentence
• float = no. / decimal
• int = whole no.

Circuit boards

• RHS = analog in
• LHS = digital output
• sensor – input – output – motor etc
• converter chip to USB so we don’t have to use old ports
• press reset button on board when trouble-shooting

Bread boards

• short leg = ground
• long leg = positive
• potentiometer regulates supply
• create circuit that loops back to the battery
• extend circuit to pin more things in, all of which have to be connected through the same ground. Use same line on breadboard to ground(?)

Functional Circuit and LED

• Circuit board:
• Digital side: Ground to bread board RHS 56
• pin 13 to bread board LHS 55
• LED short leg (ground) to RHS 55, long leg (+ve) LHS 56
• extend circuit: copy code X 3 and change code for pin no. to new pin no.
• ground wire and new pin wire
• Proximity Sensor
• LED flashing / interference
• introduce variables, e.g. if distance is greater than 1oo etc in code
• + counter: ++ = + 1
