From the Forums: Building the Pixel Box – a light-up NeoPixel coaster
Light up your drink in style! From the Adafruit Forums, user kazzle101 documents their build of a NeoPixel ring lighted drink coaster:
This all started with wanting to modify a cheap camping light replacing the LED’s with NeoPixels. So I made a PCB disc to match the existing board that held the LED’s, as well as a board for an ATtiny85 microcontroller, plus a microphone and vibrating motor. The battery and charging circuit came from a cheap (Poundland) USB powerbank. It turned out that the battery from the powerbank didn’t fit in the camping light, so what to do instead?
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
