== Computation and Communication with Knots == | |||
<br> | |||
This "machine" is capable of two things: <br> | |||
- it can help the user to conduct simple (and complex - if developed further) calculations and <br> | |||
- it can be used as a communication tool for two people by translating messages in a kind of morse code<br><br> | |||
Components: | |||
- Wood (left overs) <br> | |||
- two pieces of threaded rod <br> | |||
- two 3D printed wheels <br> | |||
- a ball bearing that fits to the threaded rod<br> | |||
- and thread<br><br> | |||

How to use it:<br><br> | |||
1. Use the winder to make the knots scratch the thin plastic plate <br> | |||
2. Wind the thread until the red section crosses the thin plastic plate <br> | |||
3. Move the winder forward to add "knot-scratches" <br> | |||
4. Move the winder backward to subtract "knot-scratches" <br> | |||
5. Enter your calculation <br> | |||
6. Wind back to the red mark and count the "scratches"- <br> | |||
they represent the result of your calculation!<br><br> | |||

== Braiding == | |||
<br> | |||
This "braiding board" is an experimenting platform for different braiding techniques.<br> | |||
Its level of complexity can be modified by changing different parameters. <br> | |||
It consists of five "thread ports"and "thread gaps", forty interchangeable "spacers"and fifty "spacer slots". <br> | |||
<br><br> | |||
Components: | |||
- Wood (left over) <br> | |||
- five pieces of thread <br> | |||
- forty wooden dowels <br> | |||
- and five screwable rings <br><br> | |||
[[File:thread_cont_board.jpg]]<br><br> | |||
How to use it:<br><br> | |||
1. Define your setting: plug the spacers in / out <br> | |||
2. Insert each thread into a ring <br> | |||
3. Think of an algorithm / a braiding technique / your experiment <br> | |||
4. Note: the order of the threads in the "clipboard" (bottom of the board) makes a big difference <br> | |||
5. Start braiding! <br><br> | |||

== Networks == | |||
<br> | |||
How can we visualize or encode networks in a different way than we are used to ?<br><br> | |||
This sketch is a proposal to transform networks and their different parameters by shaping braids / thread patterns. <br> | |||
It is not predictable that random braid configurations evolve into proper braid structures that can exist without any outer support.<br> | |||
Therefore the "machine" above ("braiding") shall be used to set up a thread-path that does not fall apart easily.<br><br> | |||
The structure of the transformation is defined by several parameters that represent different properties of the network.<br><br> | |||
Example:<br> | |||
- the network could visualize trading routes between cities<br> | |||
- the colors could then represent different goods, for instance: yellow = red pedal boats<br> | |||
- A,B,C and D represent the nodes of the network. In this case they could represent the cities.<br> | |||
- the amount of goods can be represented by the location of a color inside the four squares of A,B,.. counted from left to right.<br> If the second square of A is yellow than this could mean that city A has 200 paddle boats.<br> | |||
- now, a match of the colors AND the locations of the colors inside of A,B,C or D means that those two or more cities (nodes) exchange goods (are connected).<br> | |||
In this example: A and B's second squares are yellow -> those two cities trade 200 paddle boats.<br> | |||
- if there is no match then there is no connection.<br><br> | |||
The "braids" and the network drawings can be infinitely translated into each other.<br><br> | |||

== Levers and Cranes == | |||
<br> | |||
How can we move something in every three dimensional direction? <br><br> | |||
A mechanical feature of thread is that it can pull - but it can't push. <br> | |||
This structure helps to move things with thread by the use of additional mechanical support.<br> | |||
It is meant to be used by two peoples who operate two strings (yellow, each person) in order to move the object.<br><br> | |||
One important part of that structure is a spring (green). <br> | |||
It is attached to a fixed spot in the room. It stretches and contracts itself when the attached object is moved 1) parallel to the ground and 2) up and down. <br><br> | |||
Another essential aspect is the thread that goes through / is attached to the middle of the object. <br> | |||
It holds the object in place so that a precise movement is assured.<br> | |||
It also takes away some of the objects weight in order to exonerate the operator strings.<br><br> | |||
A third important part are the structures that attach the "middle-thread" (red) to the ceiling and the ground.<br> | |||
They 1) hold the middle-thread in place, they 2) react to the operators movements by turning in the required direction (blue wheel) and they 3) provide a bracket for the spring.<br> | |||

== Pulleys == | |||
<br> | |||
This is an assembly kit that allows to work with pulley/thread constructions in a flexible way. <br> | |||
It works best with flat and smooth surfaces and it can be used in vertical and horizontal constructions<br> (such as logical operations, see Rachel Smith's and + or gates).<br> | |||
The parts:<br> | |||
1) 3D printed pulley wheels <br> | |||
2) metal ball bearings <br> | |||
3) plastic suction pads and <br> | |||
4) thread. | |||
