[Kyri] has made a simple circuit to do color detection using an RGB LED. Simply set the LED to the color you want to detect then wave the object over it. Another LED will light up if the object is the ...

[Tomas] wanted to try building something mechanical with electronic control, and ended up with this sorter that organizes beads into one of two containers based on color. He built most of the ...

University of Central Florida (UCF) researcher Debashis Chanda, a professor at UCF's NanoScience Technology Center, has developed a new technique to detect long wave infrared (LWIR) photons of ...

With genetically engineered color vision, gut-dwelling bacteria transform into vibrant artists—though their work is a bit derivative. In a study published in Nature Chemical Biology, MIT researchers ...
