Ferrofluid ( and lots of failures)

Melany attempted to make an electromagnet that used ferrofluise as the core.They didn't spike the way we wanted them to, but it did make a bump.

I was able to wrap an electromagnet using enameled copper wire, that spiked the way we wanted. The spikes aren't on as large of a scale as we would like them to be, but this is the first successful electromagnet we have made so far.

Building the first of three boxes for the final

Rhino model of what we imagine our final to look like. We planned to have three separate boxes that would serve as "aquariums" with electromagnets in each of them that would respond to different stimuli ( sound, vibration, and light).

Our crit for this idea did not go well. It was suggested that we CNC route the boxes instead of hand cutting them. The boxes are too tall and use a lot of material. We are thinking about going back to our original idea of having a horizontal surface ( a table), instead of the three boxes we were planning on.

Working Module ( finally)

For this week, we were required to have a working module of our final project to present to various professors and a visiting artist from Berlin. The module is an array of electromagnets and photoresistors , which allowed the electromagnets to turn on in response to changes in light. The electromagnets were constructed out of lag bolts and enameled wire that Keegan took from transformers.

We received positive feedback from most of the professors and visitors. They seemed to like our idea of the predator and prey relationships of garden eels we were trying to mimic ( the garden eels would be the electromagnets, while the people interacting with the module would be the predators).

During our presentation, we mentioned trying out different shaped magnets and seeing how the ferrofluid reacts with then. Max suggested using just the enameled wire in the ferrofluid and seeing what sorts of reactions we get. Right now we are using a lot of energy to power just a small module.

Final Project Movement Mechanisms

After our last critique, it seemed like we were all on board with the general idea of mimicking the shoaling of fish. To move forward with this idea, we had to figure out the movement mechanisms that would allow for us to achieve the effect we were going for.

None of these mechanisms ended up working. So we decided to move forward with Ferrofluid ( something we had tested during this week out of curiosity).

Idea Generation/ Brainstorming

After an extremely long meeting which consisted of each person discussing their different bioinspirations and how their projects could take form, we came up with a list of about 17 different ideas. The process of narrowing down was done by everyone re-explaining their ideas and then by voting. We rediscussed the ideas that got the majority of the votes, and narrowed it down to two ideas :

1. Carlo's idea of having a wall stacked shapes that would respond to some sort stimuli and make noise when they moved.

2. a collection of surfaces that mimic a shoal of fish

We decided to move forward with the shoal of fish idea, especially because it had more of a biomimetic story behind it

Final Project Design Process/ Brainstorming

I was pretty excited to hear that the final project will be open-ended. Our past mini-projects have been more about the mechanics and arduino, and less about the biomimcry ( which is what I was most looking forward to). We usually thought about the design first, and came up with the biomimicry during the process, which was also usually designated by the project constraints.

When doing our " team designing", we had to come up with individual goals. One of mine was that I wanted the biomimcry to be an important aspect of the design and be reflected in the design, not just be some sort of explanation after.

Our first brainstorming session consisted of everyone coming up with different bioinspirations and possible designs that could fit with them.
