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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
