Summer is here, which means it’s time to break out the super soaker. Smithsonian takes a dive into how Lonnie Johnson invented it.
You might think it doesn’t take a rocket scientist to invent a squirt gun like the Super Soaker. But Lonnie Johnson, the inventor who devised this hugely popular toy that can drench half the neighborhood with a single pull of the trigger, actually worked on the Galileo and Cassini satellite programs and at NASA’s Jet Propulsion Laboratory, where he helped develop the B2 stealth bomber.
Johnson is a prodigious creator, holding more than 120 patents on a variety of products and processes, including designs for film lithium batteries, electrochemical conversion systems, heat pumps, therminonic generators and various items to enhance battery production, including a thin-film ceramic proton-conducting electrolyte. In addition to serious-science inventions, Johnson has also patented such versatile and amusing concepts as a hair drying curler apparatus, wet diaper detector, toy rocket launcher and Nerf Blasters. Yes, that rapid-fire system with foam darts that tempts the child in all of us to mount ambushes on unsuspecting relatives and pets.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
