use TWO FLEXINOL on one panel to amplify movement
The new prototype applied one more flexinol in the same panel. So that when we can hang the whole structure onto the roof, the space movement created at the human level will be amplified .
The diagram below shows our final application, which is a movable wall that creates a private space outside Room 300 Avery Hall. So essentially, a sensor would detect a person's movement, while he enters the space and triggers the wall to open, letting the person into the space. The second group of sensors detect the movement of the person after he sits down, triggers the wall to close, and creates an intimate space.

We tried to experiment with a thicker flexinol wire to gain more power and more movement to our system. We changed the material from cardboard to bass wood and increased the length of the piece of wood, to test the limit of strengh of new thick flexinol. The longer the flexinol, the stronger the strengh it produces, while consuming more energy.
use THICK FLEXINOL
Things learned this week: Never buy Radio Shack brand Batteries, spend a little more on buying Duracell! Radio Shack Batteries run out SO FAST!!

use TWO RELAYS and TWO OUTPUTS with modified CODE
For the third prototpye we connected two relays and two power sources (9-vott batteries) to create two different flexinol outputs. And by modifying the code, we created a sequence of movement for each output. When triggering the sensor, one prototype would move, then the second would move afterwards. This creates a rhythmic organic wavy movement.

How to use a relay: by ELEGON team
Team: Anond Adrian Arunsmith, Esther Chu, Gao Tian, Phuttipan Aswakool, Tao Liu
A relay is a device that enables you to aquire electricity from an alternate source (ex. another 9v battery) directly to the flexinol wire instead of going through the bread board system. This will give you more power to go to the flexinol and will create stronger contractions in the wire.
Relays come in many sizes and prices, but the most appropriate one to get is the smallest which will be able to plug directly into the breadboard (as seen in the picture). Relays can be purchased at Radioshack on Broadway and 109st the price for this one is about $2.99. Diagrams of how to connect a relay to the existing board system can be seen in our previous post by the ELEGON team.
Using a relay to increase the input power is a good option for teams that do not get enough movement in the flexinol as they want.

use RELAY to get more movement
We try to introduce the use of relay into our new prototype this week, in order to get more power by connecting to two batteries , so that our flexinol wire can get its own individual source of electricity, to get a great movement. Above diagram shows how the relay is connected to the breadboard and the second battery.
We also improved our 1st prototype's mechanism by introducing this "wings" like system to help better attach our skin to the system to create the wave-like movement we desire. The strength of the thin flexinol is rather weak, and the longer the flexinol is the greater the power it consumes. Thus, we are planning to try on a thicker flexinol for protoype 3.

sensor + relay: The movement is more greater than the set up without relay.
Prototype 2 + relay: The movement is not as smooth as we've expected, which might due to the extra length of flexinol we used took up more electricity, thus the movement is not as great as we would like it to be.

We started by designing a frame that moves sideways when connected to the flexinol wire.

assigment 1
The first part worked easily although the flexinol wire contracted very little.
For the second part, since the picture showing how the wires connected on the breadboard is not so clear, we tried to read the code " input 0" as connecting the hole "P0". and connecting the yellow wire from the sensor to that hole.
After running the code, the screen says "cleared 016" at first. And when we shake our hand in front of the sensor, the screen says "tripped 017". The number changes as we add more movements.
