Finally got them to work.

The initial phases of my interface, created using plywood:

The main box, stained ebony:

I then followed Charlie's advice regarding creating a small box to hold my fan and dust sensor together. I created two frames, one for each component/sensor, that I then attached together using wooden dowels. 

I stained the small rack, and gave my interface a second coat of stain.

After troubleshooting with Charlie about possible reasons why the dust sensor didn't work for my second mini-project, resistors were added in parallel and in-series to help bring the voltage that the dust sensor's LED received closer to that used in the example code and schematic from http://arduinodev.woofex.net/2012/12/01/standalone-sharp-dust-sensor/

My dust sensor stopped functioning properly again, so I troubleshot with Charlie; he suggested soldering the components directly into my perma board, which solved the issue:

Images of overall set-up:

For this project, I was originally interested in having the act of sifting through evidence or scraps of a story written on burnt paper affect the quality of light/images from a projector. In this piece, an alternate version of my second mini-project, the projector functions as a light source; the heart of this version involved the light moving via a reflective piece of metal to illuminate different portions of the paper as the viewer sifts, tying into the concept of secrets.  This piece also builds on a project I created in my Experimental Drawing course, taken during spring semester.

My original design for this alternate version involved secrets written on the horizontal piece of paper that were revealed as the light moved; after receiving feedback from crit, I feel as if the piece would have benefitted from the inclusion of this text.

Mini Project 1

When originally looking at what I wanted my final project to be, I thought I would want the human interaction to involved touch of some sort.


So I tried out multiple pressure sensors. The project theme was signal and I wanted to get the signal to be from human interaction of some sort. After testing the pressure sensors I was exploring and found pulse sensors, I immediately had to try it out.

From touch to pulse I wanted the person to allow the signal to happen. I used a pressure sensor to turn an LED on and then I also used a pulse sensor and it communicated to processing, this was vital for my final project because it's when I realized that I could use some of the coding we learned in programming and put it to use (finally).

I had no idea what the sensors did. Ivette and I were exploring and testing things so here is the research that I had to do to figure out what I was working with exactly.

I had to follow a tutorial but it felt like some of the info was missing so I had to wing it:

ANNIE KLOPP | Wave Shield and WaveHC library

In order to get my wave shield working (when it was initially working) I had to install the WaveHC library properly.

The WaveHC library provides a large library for plenty of options with the wave shield. Some of the programs it provides that are listed on the tutorial website are a 6 button player, playing the same sound once, or playing all the sounds on the SD card continuously.

ANNIE KLOPP | Multimeter Activity

Continuity 

Continuity can be measured by simply touching the negative and positive ends of the multimeter together. When I do this with this multimeter, I get a continuous beeping sound.

Resistance

I used several various resistors in my kit for this activity.

Voltage

I measured a 9V battery as well as a power adapter, since they mentioned you can measure these as well. These results came out to roughly the same voltage but not the exact same.  For example, 9V battery ended up having slightly over 9V of power.

this is the power adapter I used. 

Current 

You must actually break the circuit to measure current!  There is a warning that this can be a dangerous thing to measure.  I measured a simple LED circuit.
