Every day, we come in contact with objects that are injection molded – one of the cornerstone technologies that define our modern world. Injection molding allows designers to create extremely complicated parts with relatively low part cost after a (usually expensive) initial investment in an injection mold.
Injection molds are often closely guarded trade secrets – Legos is said to bury worn-out molds in the concrete of its new buildings. However, since we are an open sourced project, working closely with our manufacturing parters, I am able to give you a behind-the-scenes look at how injection molds are built.
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.
