Midterm Concept
Concept: Using inorganic materials to create the sense of anilanted organic, I want to create a small mechanical object that references sea anemones’ movement. The anemone will be created using vinyl tubes, wire and an actuator (ideally nitinol wire). 
Composition: The actuators will cause the tubes to contract inward creating a closed off shape when a person or object is too close to the anemone. Once the intrusion has left the anemone will begin to open again. 
Context: The delicate nature of a sea anemone’s movement and it’s grip on things that intrude into its tendrils interest me. This delicate nature of the movement will ideally be reflected in the actuation through nitinol wire and it’s silent movement. 
Materials:

Nitinol Wire:  20-30’ @ 
Vinyl tubing: 20-30’ @ ⅛”-¼” 
High Current Power supply
Relays 5-10
Arduino
Rubber bands
LEDs 5mm blue & green 10 each
Range finder

Power to Relays to Nitinol wire 5A
Range finder to Arduino to relays to trigger nitinol
Nitinol will cool allowing the rubber bands to pull them back

Today was crazy… Started with thinking my radios were good to go only to have the reality of how little I understood the PCB process and how it affected my ability to trouble shoot.

After hours of trying to work out their malfunction I caved and set to work creating a hard wired version so justin and I could make some noise.

Shortly there after we discovered the bluefruit ez link (which I’m positive is the physical manifestation of magic)

I dove into making a new board for the sensors to run off a promini and the ez link. The sensors might not be autonomous, but the lack of clunky adruinos at the computer make up for it.

I am looking forward to tackling the mysteries of 433mhz radios as we continue on this project.

Justin and I find that our strengths and interests in this work compliment each other well.

We are excited to show our work in this iteration, but more interested in what the process has been bringing to light for future iterations. We have a running list of what to work on next.

Saturday was a productive day of costume building. We’re well on our way to making this thing talk. This morning will be spent trying to make the wireless boards talk to each other. Hopefully by this evening we will have four autonomous sensor packs transmitting back to the base arduino uno. Circuits to come soon.

Sensor -> Arduino -> maxMSP -> Ableton = winning with Justin Peake

Toys toys toys! Play time with Justin in the pcomp lab.

We have data coming in from 3types of sensors: accelerometer, flex and pressure. They are a good start to making the costume trigger and alter the sounds.

We are currently focusing on the knees, feet, elbows and hands. This may grow into a more complex system as the semester progresses.

We have been prototyping bringing the data into maxMSP to ableton with simple breadboarded versions of the sensors.

By Sunday we are hoping to have the low power wireless and pro mini set up rolling so each limb can more freely and the electronics embedded into a finished product by the final.

The work may turn into a conversation between musician and dancer through the computer, but we are not sure where this iteration is taking us yet.

More serial fun times to be had tomorrow as all the toys will have arrived en bulk! Weeeeeeeeee!

(I got help from second year Kina Smith to make some PCBs for the wireless boards)

Nitinol exploration

1.5mm is a bit tough to work with. I found that it is easy enough to anneal and get reactions from flame based heat, but getting it to react based on electricity is another story. I just order some thinner wire at .3mm and I’ll see if I can get it to wiggle, the almighty google tells me the .3mm wire will need about 5A to contract… we’ll see..

Curls!

Moar!
