Wearable Tech Projects: Handy Sampler: a sound glove with #HalloWing #Wearables #PythonHardware #CircuitPython #Adafruit @SophyWong @HackSpaceMag @Adafruit

From the new book Wearable Tech Projects by Sophy Wong – Handy Sampler: a sound glove with made with the Adafruit HalloWing.

We couldn’t wait to get our hands on the new HalloWing M0 Express from Adafruit. Based on the Feather M0 Express microcontroller, the HalloWing comes packed with on-board features like a 1.44” full-color TFT display, accelerometer, light sensor, speaker driver, and JST ports for connecting NeoPixel strips, sensor inputs, and more. All of this, plus a built-in on-off switch, means the HalloWing is just asking to be put into a wearable project – that’s what we did. Behold the Handy Sampler: a wearable audio sampler glove!

Our glove is more of a sampler than a synth: you can record your own sounds and load them into the 8MB of SPI flash on the HalloWing. We added capacitive touch sensors to the tips of the fingers for triggering each sound. Just press your thumb and finger together to trigger one of four pre-recorded sounds. And the TFT display shows your awesome synth-pop band logo, or a picture of your cat, or anything else you can fit into a 128×128 pixel BMP image.

This project is easily coded using CircuitPython, the “edit in a text editor, drop the file on the flash drive and it runs automagically” language.

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. Updates to this page will happen frequently. Our blog and social media platforms will be utilized in actionable ways. Specific actions each week noted and shared as part of our all-company “State of the Fruit” notes and all-company meeting. 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 adafruit.com/blacklivesmatter
