Are you interested in workshops at HeatSync Labs

I just posted this to the HeatSync Labs discussion group asking to see which workshop people are interested in attending.

Chime in if you are are interested in any of the following. I'll host these for $10 per ticket and the lab gets their 30% cut of that.

Light Box Workshop (more info)
Paper Electronics (more info)
Touch Sensitive Robot Soldering (Bartholomew Workshop)

Light Box Workshop

On Tuesday at Queen Creek Maker Night we made awesome light boxes. Everyone had a lot of fun making them. The cool part is you don't even need colored lights to make it fun, just hold it up to anything with light and it looks great.

Check the videos at these links to see them in action; Exploritorium first made these in 2010. Wonderfulidea.co innovated on this idea by using Red, Green, and Blue LED's to make a version that makes colorful shadows. Also a big thanks to Make Magazine for doing the write up on the build which is where I found out about it.

To make these you mainly need mylar. In theory you could use old mylar balloons but you'd need a lot of them. I estimate 3.75 square feet (3 inch wide pieces totaling 15 feet).

We used vellum as the diffuser since I had some and it looked great, but regular printer paper also looks good. Either way you can get both mylar and vellum online.

The box frame was made with foam board, we used cling wrap to hold the parts inside. Just a bit of hot glue and clear tape to hold things together. The final touch was adding scrapbook paper on the outside to cover up the tape and give a nicer look.

Tilt Activated Rocket

For the latest paper electronic design I'm using small tilt sensors that include a tiny ball bearing in a cylinder. When the rocket is vertical it is off. Tilt it slightly and the "engine" lights up. I'm a fan of building circuits that don't waste battery life when not in use.

It would be cool to build a 3d version of this rocket that is desktop worthy.

The 5 Maker Skills

I like to tell people about the 5 maker skills. What I'm talking about is making physical things. Things like music, and writing are also creative making. The 5 maker skills are; design, fabrication, electronics, programming, and collaboration.

These terms are being used as oversimplifications and meant as a means of categorization. If you have ideas on things you'd like to make you may require some or all of the these skills.

Design:
This can be done only in your mind, on paper, on the computer, or with any kind of tool, for any kind of work. Their are CAD tools for 3d models, electronics, fashion and more.

Fabrication:
This is probably the most loosely named category. If you are physically working to make something real then that's fabrication. It may help to sub classify parts of this, but for now just realize that machining parts, filing, sanding, putting on nuts, bolts, screws, mixing chemicals for biology research, sewing, or painting. If you are painting a canvas nobody would call that fabrication, but yes that's what I mean by this broad category.

Electronics:
For this you don't have to be designing your own circuit boards to be working with electronics. Adding a couple already built components and testing out how long the batteries will work is an electronics process. Designing your own circuit boards, reverse engineering, or dealing with radio frequency rely on electronics knowledge.

Programming:
Here we are talking about anything you do to give instructions to a computer or microprocessor what to do. Of course if we are talking about making it would include a physical component somewhere. Many times people write code with no intentions beyond connecting digital stored information and showing them on screens. The great thing is any experience with computer programing will make a transition to programming physical things so much easier.

Collaboration:
This brings us to what should probably be put first. I don't want to sound like I'm trying to put fancy language around the importance of collaboration. It does certainly help when you can work with people who have knowledge, skills, and experience you don't have. Hackerspaces and Makerspaces work to provide spaces for collaboration. There are also many places on the internet that act as a way for people to connect for collaboration.

HeatSync Labs Move

HeatSync Labs is moving 250 feet away to 108 W Main St. The old location has been all but completely cleared out. The member boxes in this picture are now at the new location.

There is still a lot more work to do getting everything at the new location set up. Exciting times and lots of energy from our community making this happen.

Cardboard Electronic Pianos

We built Cardboard Electronic Pianos at the Queen Creek Library and Glendale Velma Teague Library. These are really basic with a single C scale using Arduino Nano, cardboard cut on the laser, copper tape, and a few wires. Removed a lot of complexity and left some room for upgrades to the code.

Below is the code for the piano. Could use some debounce, or the ability to play multiple notes.

#include "pitches.h"

int buttonState = 0;

int buttons[] = {
  2, 3, 4, 5, 6, 7, 8, 9
};

int tones[] = {
  NOTE_C4, NOTE_D4, NOTE_E4, NOTE_F4, NOTE_G4, NOTE_A4, NOTE_B4, NOTE_C5
};


void setup() {
  Serial.begin(9600);
  pinMode(buttons[0], INPUT_PULLUP);
  pinMode(buttons[1], INPUT_PULLUP);
  pinMode(buttons[2], INPUT_PULLUP);
  pinMode(buttons[3], INPUT_PULLUP);
  pinMode(buttons[4], INPUT_PULLUP);
  pinMode(buttons[5], INPUT_PULLUP);
  pinMode(buttons[6], INPUT_PULLUP);
  pinMode(buttons[7], INPUT_PULLUP);
  //pinMode(11, OUTPUT);
  //digitalWrite(11, LOW);
}

void loop() {
  int keypressed = false;
  for (int x = 0; x < 8; x++) {
    buttonState = digitalRead(buttons[x]);
//      Serial.print("button - ");
//      Serial.print(buttons[x]);
//      Serial.print(" - ");
//      Serial.println(buttonState);
      if (buttonState == LOW) {
        tone(12, tones[x]);
        delay(10);
        keypressed = true;
        break;
    }
  }
 
  if (!keypressed) noTone(12);

  // delay(1);
}

Paper Beads

I had fun making these paper beads at Craft night at HeatSync Labs. Craft night is the 3rd Monday of every Month at 7pm.
