Mary Walton #WHM23 #WomensHistoryMonth #WomenInSTEM
Mary Walton was a mechanical engineer and inventor from the late 19th century. In a lot of ways she was an early environmentalists; her inventions were aimed at reducing pollution from the industrial revolution. From Lemelson-MIT:
Walton’s invention (patent #221,880) deflected the emissions being produced from smokestacks into water tanks, where they were stored until they were flushed in the city sewage system. Several years later, Walton went on to address the rattling and clanging noises from the elevated trains. New York City even called upon America’s greatest inventors, including Thomas Edison, to come up with a solution.

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.
