For this week’s project, we designed and 3D printed a simple case for Circuit Playground. This bumper and 2-piece strap turns Circuit Playground into a wearable. 3D printed in Ninjaflex filament, the strap is printed flat and wraps nicely around your wrist (or leg?). The bumper bites on the edge of the PCB and holds it in place. On the bottom of the bumper are two slots, where the strap can be inserted into. The straps themselves have extensions on the end, which acts as end stoppers. The two straps snap fit together via holes and a little nub. It’s a really simple design and relatively easy to 3D print (as long as you print SLOWLY – 30mm/s).
While designing the bumper and strap in Autodesk Fusion 360, we decided to try out User Parameters – These are special parameters that allow you to quickly and easily update a values. So, instead of editing a sketch and modifying dimensions, you can open up the user Parameters dialog box and input a width or length of the strap. We also added number of holes, and the distance of them. There’s lots of other User Parameters we could add (like the overall diamater of the bumper) so we put together a Layer by Layer tutorial to show you how easy it is to setup.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
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.
