ORIGAMI project

 

GROUP name : hell yeah paper

members : GI SUNG LEE, ALEC MCCLURE, XIAOQI LIU

 

introduction of paper:

uncoated papers : carried by art stores and paper distributors. There are colored papers and embossed finishes. Their fibers align in one direction, making folding easy.

Coated Papers : highly smooth surfaces on one or both sides and are available in gloss or dull finishes of various brightness. The colored papers are good for torn sculptural effects or collage. because they reveal an attractive white edge when torn.

Handmade papers : are generally produced from cotton or linen rags and used by watercolor and etching artists. They are available from art supply stores and handmade paper companies. Their sculptural qualities are superb, because the fibers occur in a random pattern.

Specialty papers : include crepe, tracing and corrugated papers – in fact, all of the papers that fall outside of the other three groups.

 

history of the paper

paper derived from papyrus, the name of ancient egyptian material used to as a medium for writing

egyptian map is the earliest known folding of paper (same as modern road map)

wood-pulp based papers in china allowed intricate designs, first invented by Cai Lun in the 2nd century bce

first Japanese origami dated to 6th century ad

what we made

 

Test 1: Sponge, LED, two pieces of conductive fabric

In this test, the LED just lights on and off according to the palm pressor.

Test 2: Sponge, LED, two pieces of conductive fabric, a piece of velostat

As you can see, in this one, the LED has adjusting brightness by the palm pressor because of a piece of velostat. The velostat should be placed between the two small conductive fabrics.

I made pressure sensors using sponge-filled craft stars, velostat, copper tape, wires, leds, coin batteries, solder, and three different types of conductive material (copper taffeta [.05 ohms/sq], metallized nylon [< .02 ohms/sq], and copper tape over paper [.05 ohms/sq]). Before making the stars, I tried those three materials and liquid graphite, pure graphite pencil, bare conductive paint, and the electroinks conductive pen. I couldn’t get it to work with the pencil, paint, or graphite. They were too resistive for the velostat. The conductive pen worked, but it would have needed a much thicker layer to be reliable. Based on the resistance levels, I assumed the taffeta and copper tape would yield the same results, and the nylon would shine brighter. I found the nylon to be the worst, which makes no sense to non-math comprehending brain.

(1) Choose one variable to test (distance, surface area, conductive material, substrate, etc) and make three sensors to test that variable. Make a hypothesis about each test BEFORE you construct the sensor then document your result.
For example, my variable is surface area. I will make three sensors out of papper, copper tape, and velostat, but I will change the surface area of the copper tape in each sensor. I hypothesize that the more surface area for copper tape…. (complete your own thought :))

> Be sure to answer the following questions in your documentation:
> What conductive materials are used? What non-conductive materials are used?
> How much of each material is used?
> What state changes occurred in the LED if any?
> What is the resistance of the conductive material?

(2) Make sure you bring your Arduino Uno and a breadboard to the next class. You can also bring a Lilypad, Flora, Mini, etc in addition to the Arduino Uno.

(3) You are *highly* encouraged to go to Maker Faire.

(4) Watch Masimo Banzi’s TED talk

(5) Learn a New Craft Project DUE NEXT CLASS
