Patterns for Machine Knitting
• What is knitting?
• Must be two colors• Must be low resolution 100 x 60 pixels
Program Tuesday
• Low resolution– Image– Font => numbers/text– Processing patterns– interference
• Cellular Automaton– Patterns• Regular patterns• Irregular patterns -> hidden codes
Program Thursday
• Textile workshop 13:00 – 15:30
• Knitting on Brother KH-940– Knitting particulars– A knitted pixel is a “V”, 2x2 “V” can be a square– Colors, Threads, combinations– Laptop screen is not knitted surface!
• Experimenting!
PREP: For next workshop – in 2 weeks
• Idea: make a t-shirt capacitive sensor• Needed: simple for back part• Some simple continous graphical,
monumental design shapes • Prepare screens next week:– Make a collective appointment with Publication
station
• Tuesday: technology Thursday printing testing
Back to 8 x 8 – black & white
numbers
Low resolution Fonts
Suddenly: Design low resolution
• Displays, interfaces
Photoshop
• CMD N – new file• 8 x 8 pixels• Enlarge enlarge enlarge• Pencil tool• draw• CMD I => rescale to …eg 40x40• Result: terrible!!!!!
Rescale setting : Nearest Neighbor
First Practice
• Make 8 x 8 images, draw or Photoshop• Make 8 x 8 numbers• Make 8 x 8 text (in a bigger image 40 x 40)– Short Political statement• Texel = Krim! Student lib!
• Combine in “bigger” image
Processing
• Processing.org, download, install• Examples• LoadDisplayImage
Prepared example files for patterns

• http://www.openprocessing.org/sketch/159677
• http://www.openprocessing.org/sketch/159716
Practice 2
• Play around with these sketches, using your own images.
Interference
• Photoshop image small, 8x8• Rescale => 80x80• New layer• Paint bucket – pattern (make b&w patterns)• Play around with interference patterns
Why interference?
• Because of the Nordic knitting• Avoid wires which are too long at the backside• But also because it is “fun”
Complex Patterns and codes
Cellular Automatons
• A few black and white pixels: starting line• Rules to advance in “time”, next lines
• http://tutorials.siam.org/dsweb/catutorial/• JAVA has to be running
If JAVA does not run on MACOS
• Go to System Preferences• System -> JAVA• Edit trusted websites• http://shellzero.wordpress.com/

Regular structures
(for a designer): chaotic structures
Assignments
• Experiment with low resolution– Images– Text: political statement?– Patterns and codes– Combinations of everything– Your own experiments
– Prepare 80x80 B&W images for Thursday
