### Flexible surface and conductive surface

This week I make two projects and also did experiments with the voronoi code. all is here:
1.The code for making a beehive

This is the basic code, from this code it is possible to create spiral, circular and other patterns:
```/*This example illustrates a simple method to generate a set of deliberately placed points to control the structure of a voronoi diagram. This particular example create a beehive and allows many patterns to be built on it.*/ void setup() { size(600,600,P3D); //size of your intended pattern noLoop(); // don't need to use the draw loop /*unique name for your file. if left unchanged, will simply save file with current milisecond*/ String fileName= "voronoi"+millis()+".pdf"; beginRaw(PDF, fileName); //enables you to save your design to a pdf setupVoronoi(); // create your voronoi generator```

``` int spacing=150; // the distace between the centers of the hexagons float yDiffrence=(cos((float)Math.PI*2/12))*spacing; // the height of the rows int pointsOnSpiral=40; // for making a spiral int pointsOnCircle=11; // setting number of points if you want to make circles in the centers of the hexagons int circleDiameter=50; // setting the diameter if you want to make circles in the centers of the hexagons for (int j=0;j<=height/spacing;j++){ // loop for creating rows for (int i=0;i<=width/spacing;i++){ // loop for creating dots in a row , each loop cicle creates two dots (one on fot and offset from the other) float x1=spacing*i; // the x for the first point float x2=spacing*i +spacing/2; // the x for the second point float y1= j*2*(yDiffrence); // the y for the first point float y2= (j*2+1)*(yDiffrence); // the y for the second point // // this will create the beehive voronoi.addPoint(new Vec2D(x1,y1)); voronoi.addPoint(new Vec2D(x2,y2)); // this will create a spiral in the middle of each hexigon //spiral(x1,y1,pointsOnSpiral); // spiral(x2,y2,pointsOnSpiral); //this will create a circle in the middle of each hexigon // circle(x1,y1,pointsOnCircle,circleDiameter); // circle(x2,y2,pointsOnCircle,circleDiameter); } } drawVoronoi(); //renders your voronoi endRaw(); //ends the recording } void spiral (float centerX,float centerY,int drawLimitForSpiral){ int theta=0; for(int k=0;k<drawLimitForSpiral;k++){ theta +=4; //drawPoint(width/2,height/8,theta/2,theta/2); float xPos = sin(theta/2)*theta/2+centerX; float yPos = cos(theta/2)*theta/2+centerY; voronoi.addPoint(new Vec2D(xPos, yPos)); } } void circle(float cenX,float cenY, int Dlimit,float diameter){ float xPos; // will be filled with the X value of the center of the circel float yPos;// will be filled with the y value of the center of the circel for(int i=0;i<Dlimit;i++){ //loop over the number of points in the circle float _alpha = (float)Math.PI*2/Dlimit; // determines the degree position of your current point float cirtheta = i*_alpha; //current position on circle for your intended point xPos = sin(cirtheta)*diameter+cenX; yPos= cos(cirtheta)*diameter+cenY; voronoi.addPoint(new Vec2D(xPos, yPos)); } ```

``` } ```

2. The flexible surface

3. The conductive surface

THe conductive surface is made out of two pieces of conductive fabric with regular fabric in between. I used conductive fabrice with glue on one side that can stick with heat when ironing. First I glued the conductive fabric to the regular fabric. I cut it in beehive shape with the laser cutter, then, I cut the other conductive fabric (without gluing it) in the same pattern. Then I glued the fabric to the other side of the regular fabric. So the regular fabric is an insulator.
Each side of the new fabric is now conductive and I can connect one side to positive and other side to negative. I connected LED to one side of the fabric when it touches the other side it is lit.
