Steve Messam is an artist who has been working on a new sound installation project for the City of Newcastle. Called “Whistle”, the project involves the distribution of 16 steam engine whistles around the historic walls of the city. The whistles are triggered at 1pm every day by Raspberry Pis which are connected to the National Physical Laboratory’s atomic clock in London so that the timing is super-accurate. The equipment is powered by batteries which are charged from solar energy making each whistle a standalone project in itself. Nebula Labs were tasked with programming the Pis which use air instead of steam to make the whistles sound. You can read a little more about the project in the Teesdale Mercury.

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
