Eric Winbolt, Interim Head of Digital/Innovation at English Heritage, had a brainwave. “We decided to give people an idea of what it’s like to see the sunrise and sunset within the circle, and allow them to enjoy the skies over Stonehenge in real time without actually stepping inside,” he explains.
By taking a separate hemispherical snapshot of the sky from a nearby position and merging it with the master photograph of the stones, the team discovered they could create a near real-time effect for online visitors. They used an off-the-shelf, upwards-pointing, 220-degree fish-eye lens camera connected to a Raspberry Pi 3 Model A+ computer, taking images once every four minutes.

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
