Issue 20 HackSpace magazine: Modular NeoPixel patches by @sophywong #Gemma #Adafruit #NeoPixels #Wearables #CircuitPython @HackSpaceMag

The new HackSpace Magazine Issue 20 highlights Modular NeoPixel patches by Sophy Wong.

What could possibly be more amazing than hook-and-loop tape? Conductive hook-and loop tape! That’s right, your favourite fastener is available in a silver-coated version that is perfect for making a modular circuit with custom swappable components. In this tutorial, we’ll use it to create modular NeoPixel patches for a jacket.

The microcontroller and battery for this circuit will be located in the jacket, and be connected to the loop side of the hook-and-loop tape. NeoPixel LEDs will be sewn into the removable patches. Whichever patch you slap onto your jacket will light up!

A Gemma M0 microcontroller from Adafruit will control the NeoPixels, and we’ll program the Gemma with CircuitPython.

You can read Sophy’s full tutorial in Issue 20 of HackSpace Magazine (PDF pages 96 to 97).

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
