3D printing has captured the attention of a world-wide audience. Makers of all ages are producing everything from custom skateboards to flutes. It’s truly amazing…
But what comes off the build platform is generally not as strong as cast or injection molded parts. (There are some exceptions like the rocket engine printed by NASA but that’s not what we’re talking about here.)
For mere mortals on a budget… it’s about practicality and augmenting your prints with strong, plentiful, and inexpensive parts whenever possible.
Need to make a robot rock and roll? A 3D printed ball bearing won’t be round enough, so let’s use one of these steel ball-bearing casters:
This little guy can do the job nicely… but how do I incorporate it into a design?
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.
