The current global pandemic has spurred many people to search for ways to help support the overstretched medical system and many designs for personal protective equipment can now be found online, with examples ranging from 3D printed masks, to replacement respirator parts and Venturi valves, to DIY face shields.
In this guide, we’ll show how you can make this design with a 3D printer and a 2 Liter PET bottle or two (3 L may work even better if you can get one!) in case you do not have a laser cutter or Cricut vinyl/craft cutter.
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.
