The new technology, developed by Keating and a team at Harvard’s Wyss Institute, relies on printing with dithered bitmaps, a digital file format where each pixel of a grayscale image is converted into a series of black and white pixels, and the density of the black pixels is what defines the different shades of gray, rather than the pixels themselves varying in color. It’s like the way black-and-white newsprint use different sizes of black ink dots to represent shading.
The result was a 3D model of Keating’s brain that preserved all the detail shown in the MRI data, down to a resolution that’s on par with what the human eye can see from about nine inches’ distance. The team has applied the same approach to other parts of the body, too.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
