With this piece, I wanted to create an item that was sound inspired with a purpose based around sound. Due some of the parameters of the audio capture, I limited the live capture to one word.

In this case, it was “listen”. This capture created nice dips on a thin surface. I extruded it with Grasshopper to give it some thickness so it wasn’t so flat. And to make it easier use in Slicer.

I decided to contextualise this as a headphone cord wrap. The notches help the cord stay on and for it to not tangle.

[leeherequietlycoding-blog]

Dada! The 3D print! As you can see by the post it note, the print took just over an hour. I then broke/peeled off the brim and the supports except for the ones on either end so they could act as stops for the wrapping.

I did all my resizing in Rhino as that’s where I felt I had the most control to do so.

Laser cut test - Faaarrr too thin - The laser cutter also went round it twice (even though there was only one line in the file) which did not help at all

Thankfully I was also 3D printing at the same time because I wanted to have to final options.

Testing out different slicing methods before exporting as a .dxf

Note: There is a error with Slicer for Fusion 360 that doesn’t produce sheets. To go around this just do a 180 degree flip of the cut direction

I removed the scale option as the model produced, Slicer was not the biggest fan of. But at least I could resize in Slicer if needed. (At least that’s what I think is happening)

[leeherequietlycoding-blog]

SpreadsheetIn still not working.

This was even after I had installed the OpenXMLSDkv2 which I hadn’t first time round.

So yeah.

Not sure what is happening. Think I may fall back onto the live input method to make a vague soundwave.

Accidentally loaded csv into SpreadsheetIn (found in g_Howl Example folder) in Grasshopper. Doesn’t work that way.

Remember to read and double check file types before you tweak your code.

Here’s the code anyway though:

 // use the getLineIn method of the Minim object to get an AudioInput  in = minim.getLineIn();

 table = new Table();  table.addColumn("Data"); }

void keyPressed() {  if ( key == 'm' || key == 'M' )  {    if ( in.isMonitoring() )    {      in.disableMonitoring();    } else    {      in.enableMonitoring();    }  } } void draw() {  background(0);  stroke(255);

LiveInput to Grasshopper

Here is the code to live input into Grasshopper to make a 3d model in Rhino.

This one actually works (even if keyPressed is only for the sake of the text and hearing yourself)

 // use the getLineIn method of the Minim object to get an AudioInput  in = minim.getLineIn();

}

void keyPressed() {  if ( key == 'm' || key == 'M' )  {    if ( in.isMonitoring() )    {      in.disableMonitoring();    }    else    {      in.enableMonitoring();    }  }  } void draw() {  background(0);  stroke(255);  String message = "";

 // draw the waveforms so we can see what we are monitoring  for(int i = 0; i < in.bufferSize() - 1; i++)  {    line( i, 50 + in.left.get(i)*50, i+1, 50 + in.left.get(i+1)*50 );    float x1 = map(i, 0, in.bufferSize(), 0, width);    float x11 = 50 + in.left.get(i)*50;

   message = message + String.valueOf(x1) + "," + String.valueOf(x11)+ ";";

   println(message + String.valueOf(x1) + "," + String.valueOf(x11)+ ";");  }

{     String monitoringState = in.isMonitoring() ? "enabled" : "disabled";  text( "Input monitoring: " + monitoringState + ".", 5, 15 );

}    String ip       = "127.0.0.1";  // the remote IP address  int port        = 6400;    // the destination port  udps.send( message, ip, port );  message = "";  delay(50);  }

.csv test

Since I now have Grasshopper somewhat figured out, I thought I would go back and try to see if I could spreadsheet a sound wave to counteract the continually monitoring input.This one doesn’t work

 mySerial = new Serial(this, in);

 table = new Table();  table.addColumn("Data"); }

void keyPressed() {  if ( key == 'm' || key == 'M' )  {    if ( in.isMonitoring() )    {      in.disableMonitoring();    } else    {      in.enableMonitoring();    }  } } void draw() {  background(0);  stroke(255);

 // draw the waveforms so we can see what we are monitoring  for (int i = 0; i < in.bufferSize() - 1; i++)  {    line( i, 50 + in.left.get(i)*50, i+1, 50 + in.left.get(i+1)*50 );    float x1 = map(i, 0, in.bufferSize(), 0, width);    float x11 = 50 + in.left.get(i)*50;

   message = message + String.valueOf(x1) + "," + String.valueOf(x11)+ ";";

   if (keyPressed == true) {      String value = mySerial.readString();      if (value != null)

       newRow = table.addRow();      //place the new row and value under the "Data" column      newRow.setString("Data", value);      {        String monitoringState = in.isMonitoring() ? "enabled" : "disabled";        text( "Input monitoring: " + monitoringState + ".", 5, 15 );      }    }  } }

//void saveData(){ //table = new Table();

//table.addColumn ("Audio Data");

//TableRow newRow = Table.addRow(); //newRow.setString ( println(String.valueOf(x1) + "," + String.valueOf(x11)+ ";");

//}

//void addEntry(String time, int reading) { //    readings.addRow(); //    readings.setString((readings.getRowCount()-1), "Time", time); //    readings.setInt((readings.getRowCount()-1), "Value", reading); //}

//void saveReadings() { //    saveTable(readings, <filename>); //} void mousePressed() {  //save as a table in csv format(data/table - data folder name table)  saveTable(table, "data/table.csv");  exit(); }

Feels super late to have figured this but:

println(i) is not the value of the audio wave

print (i < in.bufferSize() - 1) (more of what it is buffering?)

println(message + String.valueOf(x1) + "," + String.valueOf(x11)+ ";"); is the values of the wave as it looks closest to the values in Grashopper

So going to retry the spreadsheet idea

[leeherequietlycoding-blog]

So if you attach ScaleNU (not uniform scale lets you control each axis) and then Extrude after that, you get a scalable wave with some thickness

And yes, this one bakes!!

[leeherequietlycoding-blog]

How to scale in Grasshopper

Use integers - negative and positive WHOLE numbers do the same thing as each other eg. -10 scale will scale the model up as much as 10

Set slider to -1 to 1 and have start at 0

[leeherequietlycoding-blog]

Trying to build in Offest surface in Grasshopper

Not agreeing with me as it is now not baking

Grasshopper Offest stuff found here (VaseThickness)

Other methods of adding thickness that I tried http://www.grasshopper3d.com/forum/topics/extrude-surface-upon-surface-direction

http://www.grasshopper3d.com/forum/topics/how-to-add-thickness-to-the-surface

http://www.grasshopper3d.com/forum/topics/add-thickness-to-a-surface-for-3d-printing?id=2985220%3ATopic%3A1654428&page=2#comments

EDIT: I think part of my issue was that the thickness I wanted to add was really small to the point on unnoticable to the model so I couldn’t tell if it had been added

[leeherequietlycoding-blog]

Just trying out a different option to live input to have all the data from audio input rather than the snippet it keeps.

Currently it doesn’t print data into sheet
