New Guide: PaperCrafted Crystal Gems on a NeoPixel Strand – Beginner Tutorial
Check out the latest Learn Guide from Erin St Blaine: fold beautiful paper-craft crystal gemstones and make diffusers for Adafruit’s NeoPixel Dot strand. The sample code has four different variable animation modes ready to go, and it’s easy to customize to add your own modes or tweak the ones in the code to create your own custom color combinations. From the guide:
These crystals are made from iridescent cellophane wrap (from the craft store, like you find in fancy gift baskets) that has been crinkled up and then run through a laminating machine. They can be cut by hand with a utility knife, or cut out on a vinyl cutting machine like a Cricut or Silhouette.
Then they are folded into shape, tab-in-slot style, and finally we add a small piece of iridescent cellophane inside to mimic the crystalline occlusions. This is surprisingly convincing — they look like the real thing, but are light and flexible — perfect for cosplay applications or just stringing up around the house.
The crystal patterns in this guide are designed to slot perfectly around Adafruit’s NeoPixel Dot strand. Each strand has 20 lights, and we’ve included crystal patterns in varying shapes and sizes, so you can customize the look of your strand.
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
