…Liberty Bell differs from Koons’s sculptures in one significant way: it is a near-perfect replica of an imperfect object. When making a faithful reproduction, Koons will often distort some other feature, like size (think: giant balloon dogs) or surface (giant, mirror-polished balloon dogs). His work also traffics in composite ideals—to create his eight-foot Balloon Venus he inflated and tied hundreds of balloons so that he could select the perfect buttocks, breast, and head of each. Liberty Bell is anything but ideal; in fact, the object’s most well-known feature is its flaw.
Koons was given after-hours access to the Liberty Bell, in Philadelphia, to conduct structured-light scans. Performed by Direct Dimensions, the scans work by projecting a known pattern onto an unknown surface and measuring the distortions. (This is significantly less detailed than C.T. scans—generally used to capture all the external and internal data, of, say, a brain tumor—which Koons has begun using for his “Balloon” series. But he couldn’t very well disassemble a national treasure.)
The point cloud data from the structured-light scans were stitched together and converted into a 3D computer rendering at Koons’s studio. All variety of CAD (computer aided design) software, such as Rhino, is used to manipulate those renderings, and some data sets are so complex that simply processing them can take up to a year, as was the case with Koons’s Pink Ballerina, a yet unfinished work five years in the making….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
