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!

Overall Design Progress

The latest visualizations and drawings of the project, closing in on a final design. Prepared for use during a presentation to the residents tomorrow morning. Work continues on the overall structure, connection details, the fan+controller carriage, and software. Controllers are being fabricated now by our partner, K1ND. One more day of planning and final design, cell fabrication will start in full on Tuesday.

Pentagon Tiling

In searching for a good geometric system for the tiling of the pillows, we have become very interested in pentagon tiling. This system allows for a great deal of variation in the pattern while using the same shape. While we are not entirely constrained to use only one shape, this will make the fabrication process easier, and allow us to continue to design the overall shape after we start production of the individual pillows.

The definition of pentagon tiling patterns is a rich mathematical subject, with new patterns continuing to be discovered. So far, 15 have been discovered, the most recent in 2015. We are focusing on types 7 and 8, as they produce the most interesting, non-repetitive patterns:

More work on the simulation and overall layout. Received new, more powerful fans. Honing in on the final schematics for the controllers. Bought waterproof fabric and elastics. Testing tiling patterns. A few images and animation from the past 2 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.

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
