Prototype 1 (w/ movement) - This is an example of the contraction we want to create with the fixture. By locating 5 critical points along the centerline of the 3D object and attaching string to these points we were able to do so. To create the desired pull with the string we used a straw to push down, therefore keeping the pulls more controlled and therefore the fixture's movement more predictable. 

Moving forward we plan to use the servo motor, powered by the Arduino, to control the pull of the string.

If you don’t know what Grasshopper is (or think it’s a reference to Kwai Chang Caine), you are already in the wastelands of the digital age. It is one of the leading factors of Architecture 3.0, the second computational revolution for building design. This new phase is shortening the design process from months to days , and allowing a new generation to envision, design, and execute major projects with a single laptop.

Progress toward our goal of expanding and contracting our weave using a pulley system and servo. The shifting density of the weave reveals what is behind the weave in varying ways. Movement will be prompted by sound (a byproduct of wind), but today we practiced with a potentiameter.

Interactive Proximity Sensing Table. The concept behind this table is similar to the motion proximity that we are trying to achieve with our light.

The project has moved into the prototyping phase.  Ive created a form consisting of two identical parts that opens to form a continuous surface.  I am fabricating the form with Lasercut ribs drawn from the surface geometry using grasshopper.  The opening motion will be triggered by a proximity sensor through arduino and will cause the two halves to slowly rise transforming into the continuous surface floating just above head height.  I am experimenting with using grasshopper to color the ribs from the center of the form outward OR from the center Plane outward.  The idea is that there is a relationship of inside to outside and top to bottom that is experienced through the transformation.  Also it is an interesting real world visualization of the analytical potential of grasshopper.

My prototype uses a paralax continuous rotation servo controlled with a radio transmitter and receiver all powered by batteries.  The final project will be powered by a high torque stepper motor and controlled by arduino and a proximity sensor.  The servo was barely strong enough to lift this empty shell of my project.  The platform is made of basswood and the pulley made of MDF

Prototype Fabrication Issue

We are trying to get our pieces ready for fabrication. We are having issues with making the tabs to join the edges. This is the only way to unroll, without overlapping edges. We are trying to find an efficient and clean solution. Any ideas?

--- Alvaro: The idea of prototyping sometimes is to find  that our geometry doesnt actually work. This is why we can go back and forth between the laser and the software. .. or even just catching mistakes within the software- This is the real advantage of digital fabrication. 

I can not really tell from the photo what the problem is. But if you are having only issues with the Paneling Tools Tabs command and your geometry is working fine then manually offset the border in Rhino with command: offset. 

I really encourage you to cut one strip ASAP so you can change your design accordingly on time. LEDs wiring is not going to be an easy step either.

Stepper Motors

A stepper motor is a motor controlled by a series of electromagnetic coils. The center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not, creating magnetic fields which repulse or attract the magnets on the shaft, causing the motor to rotate.

This design allows for very precise control of the motor: by proper pulsing, it can be turned in very accurate steps of set degree increments (for example, two-degree increments, half-degree increments, etc.). They are used in printers, disk drives, and other devices where precise positioning of the motor is necessary.

There are two basic types of stepper motors, unipolar steppers and bipolar steppers.
