In the final part of our series on hyperaccumulators, we take a look at those who go above and beyond the call of duty by helping people clean up the nastiest of pollutants: solvents, hydrocarbons, and radionuclides. I’ve worked with the BTEX family before (benzene, toluene, ethylbenzene, and xylenes) and they are no joke. Major props to the white rot fungus on that one. And could you ask for a better beacon of hope than the sunflower?
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.
