Sundvor demoed the Nima testing process at the SXSW happy hour. First he placed a morsel of the dastardly chicken in a capsule and twisted the cap shut, which has the effect of grinding the food inside and releasing a solution to extract the protein. He then inserted the capsule into the triangular Nima, triggering the release of a chemical that reacts to gluten and creates marks on a paper test strip. That chemistry step takes about two minutes. Finally, a tiny optical sensor inside the device checked the strip and translated the information into a simple binary result: a smiley face or a frowny face.

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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
