Final Prototypes + Tests

Testing the final fan characteristics, pillow shape and size, pillow connection details, LED’s. Pillows and electronics have been sent off for fabrication. We should receive these components by Monday and/or Tuesday. Sadly we were not able to find a suitable fan that could be run in both directions, so we will only have inflation (with at 12v 1a fan), unless we can find a reasonable way to rig up two fans in the pillow. Tests so far indicate that two fans is too much weight.

Structure elements are purchased and on site. Still need to figure out the carriage design. Will start using the controller prototype to start testing the software this weekend. Final installation fast approaching!

Octopus Pavilion Progress – 20160906

Opening in 15 Days

On Site in 8 Days

Much progress over the weekend. Full scale mock up of a 2m x 2m pillow with electronics installed, including fans, LED’s and sensors. Good tests during the day and night. We still need more power in our fans, and there are many sensitivity issues with the sensor that we are working through. The interactive company we are working with will provide a final prototype by the end of the week. Grasshopper simulation was made more usable thanks to the help of Casey and Han at MAD.

For the next few days, while we wait for the final prototype, we will focus on the overall design, including cell shape and size, overall shape in the site, carriage design, structure, and rain-screen, both in digital simulation and physical prototypes.

Octopus Pavilion Progress – 20160831

Opening in 22 Days

On Site in 15 Days

New simulation animation in site. Much to do.

This weekend workshop we will:

  • Get full prototype working with four pillows (need to buy additional electronics)
  • Test new fans and different pillow sizes
  • Work on shape and structure in simulation
  • Produce high quality renders, plans and sections

27 Days to go

Here are some videos of the physics simulation we are setting up in grasshopper to test the design and interactivity, using the kangaroo2 physics library:

Also some progress on the prototype. Working with a nice nylon type fabric, with sowing:

Hyperinflate – Inflation Simulation

balloon

First simulation of the inflation form with random fixed vertices. Face color defined by the distance of the inflating face centroid from the original centroid position. Hoping to use some development of this for the fabrication workshop later this summer. Built off the toxiclibs physics library in Processing, and this sketch in particular. Unfolded using Pepakura.

Arduino Basics (Automated Inflation)

(The first foray into Arduino programming. Pretty much following built-in examples for driving DC motors and reading analog sensors (here a IR distance sensor). The fan here was nowhere near powerful enough to inflate even a small garbage bag, but I think the principle is useful, and hopefully this is the start of a series of experiments.

And a couple useful links for future development:
