Week 11 Report

This week we started working on some prototypes in class. Kennedy Reed and I worked together using an infrared proximity sensor. We tried a few different set ups and different codes we found online, but by the time class got out we hadn't quite figured out how to get the LEDs to light up. We kept dealing with a particular error code.

I wasn't able to continue working on it unfortunately because I had work the next day. But Kennedy was able to figure out how to get it working properly. I wish I could have been more help on this particular project.

But also during the weekend prior I was able to work on a trial head sphere using 13mm thick EVA foam I bought at the Foam Forge downtown. It was much harder to cut than I thought it would be, plus I think the blade I had was super dull. But I managed to cut out 8 pieces and glue them together to form the sphere. It turned out way larger than I had imagined it would be, but in order to fit all the other pieces inside of it it has to be pretty big.
it held together pretty well using hot glue and medical paper tape (I prefer medical paper tape because it is extremely adhesive and very flexible), although for future notice, because it is porous, hotglue will ooze right through it if you're not careful (says the person her burnt the sh*t out of her leg and ruined a pair of pants when some dripped out).
Plus the sphere didn't turn out completely spherical, it had ridges where the pieces met. I wanted to try heating it up and warping the foam to be more of a curve shape, however because I used hot glue I could use the heat gun too much without all the pieces falling apart, plus it was a much thicker foam than I had originally planned on using, so it didn't bend as much I was hoping it would.

Week 10 Report

This week we worked on making light sensors using our arduinos in class.

Week 9 Report

So this week we did a little more research into our final projects, I've been looking at the electronic components and have been trying to decide what I'd like to do. Although I'm confused as to haw I want to proceed with my project. I would like to attempt the eye tracking hardware, but I feel like that might be way too much work for the amount of time that I do have.

I turned in my chapter 1 and 2 discussion notes, however we never really went over them in class.

Final Project Ideas

Tentative list of supplies needed:

  • EVA foam, 10mm, 5'x6' square
  • Worbla 
  • aluminum strips
  • bike helmet
  • 2 small stepper motors
  • 1 larger stepper motor
  • 8-10 U Groove wheels
  • Mod Podge
  • Wood Glue
  • Super glue
  • Epoxy Glue
  • Gorilla glue or Contact Cement
  • Arduino motion sensor
  • Cover for electronics
  • Paint
  • Power supply + cover

Here are the links that inspired my creation:

This one in particular is what I am interested in working with:

Here are some eye symbolism links for my research:

Week 8 Report

So this week we worked with relays in our class.
I'm stoked to finally be learning about all the different computer chip parts, I've always worked on different projects but kind of had no idea what I was actually doing, so knowing how/why each part works and what is does is super interesting. Like how relays are the piece that are used whenever its necessary to control a high power or high voltage circuit with a low power circuit.
I found a really nice video that helps explain how relays work, and the different kinds.

We also built a ...thing? in class. An arduino relay AC circuit interrupter mechanism? A thing that was cool, and quite fun to build.
But a thing none-the-less, and here is a video of the one that I made!:

Also I've been making sketches of the final project I would like to attempt to pull off.
It's been kind of difficult to know what I need to order (part-wise) because I have to be able to know what size parts I need to work around (structure-wise), but I can't figure out what parts I need until I better know the scale and weight of the pieces. So it's been a bit of a loop.

But I have some EVA foam samples on the way, and I actually have a bit of this Worbla material I got a few years ago that I never used, So I'm going to mess around with those for a bit once the samples come in.

Here's a mash up of my notes.
Also, "The Residents" are really interesting, and suuuuper trippy. But I am digging that eyeball, I need to figure out what they used for material, and also what they used for their instruments.

Week 7 Report

We had our Noise Project critique this week. I think my went over pretty well, everyone seemed to like it.
We were going to work on our Arduinos again this week, but we had another hurricane day for Michael. So the week was cut short.

But I started scheming up some plans for my final project. I would like to make a giant eyeball headdress that can look both ways and blink. I would really like to make it so that I can control it using a camera that tracks my eye movements, but that seems like it may be too complicated.

Animatronic Eye Mechanism:

Animatronic eyes using Arduino:

Eye Tracking to control a Servo:

My problem will be to
1. Program the arduino to both track my pupil movement left and right
2. Program the arduino to track when I blink
3. Be able to create the mechanical movements from inside the single eye, rather than from behind the two eyes.
4. Create a dome that is both large enough, and strong enough to withstand the weight and movements of the mechanisms, as well as contain my head.

-Maybe instead of tracking my eye movements I can get the arduino to track the movement from outside the eyeball. Like someone walking past it.

-Or maybe I can focus on the eye movements left/right with arduino, and instead have the blinking programmed with a remote.

Project 1: Noise Machine

I was inspired by how creepy the noises were that this machine made, so I wanted my interface to reflect that. I chose to incorporate doll parts (what's creepier than dolls, right?) and some expandable foam, to make it look like the dolls were fighting to escape a nightmare pit of sticky tar. The touch-points are at the end of the longer doll arms, so you have to grab their hands in order to make the machine work.
Original Noise machine on breadboard.

Here I had to cut out a hold on the bottom of the base board in order to feed the wires up through and into were the doll parts would be.

Here are the materials I used to create the base.

Here's the cover once its attached to the base. It's going to hold the electronic components and protect them from the spray foam.

Here I added a cool tree branch I found at Blackwater River. And have threaded the wiring through the hole I drilled in the blue cover. I forgot about getting the speaker through the hole ( I had already soldered it all together), so I ended up having to cut the speaker wires and re-soldering them on the other side of the blue container.

All the dolls I bought at the flea market, and some moldable plastic I ended up not using.

Here's the piece after I added the expanding foam. It's the first time I've used it, and I didn't realize how much it would expand. It ended up covering the on/off switch, and I had to scoop out the foam as it was expanding, and it got pretty messy. Also FYI, it's incredibly sticky when its still in it's liquid form. It took days before it came off my fingers. 

After letting the foam expand and settle (at least a day later), I carved some of the edges and sculpted a few parts along the branch and large doll head, but I liked the bubbly-texture around the inside arms, and decided to leave that alone. I taped up the touch points so they wouldn't be coated in paint, and could still remain conductive.

Adding the glossy black spray paint.

After spray painting a few coats I left it alone to dry for a few hours outside.

I eventually brought it in later that night, and added some finishing touches, and removed the tape covering the touch-points.

And here's the finished project in all it's creepy glory!
