On the east side of the University of Hawaiʻi at Mānoa’s campus, a 25-foot tree with long, narrow leaves and velvety brown fruit pays tribute to Alice Augusta Ball, the first woman and first African American student to receive a master’s degree from the school.
Known as a chaulmoogra, the tree was planted in 1935 in honor of Ball’s groundbreaking research on Hansen’s disease, or leprosy. As a chemist at the university—then known as the College of Hawaiʻi—in the mid-1910s, she developed one of the first effective treatments for the chronic infection, extracting oil from the chaulmoogra fruit’s seeds for injection into the bloodstream.
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.
