HACCSY app is meant to run on a RaspberryPi that’s connected to internet and the front door electric strike lock. It does the job of a simple Check in System and Door Access Control System (2 in 1), it queries a REST service by handing it the scanned in RFID card reader and it will return ‘true’ if the key owner owes less than 2 months worth of their monthly payment. It will return ‘false’ otherwise. It does the same for checking in and out. The computer would then send the signal to the door lock actuator to open it if returned true or do nothing if false. It has a check IN/OUT button to indicate Check IN or Check OUT. It also has an LCD backlight display that displays messages for the user, and an RGB LED that turns RED for Access Denied, GREEN for Access Granted and WHITE to indicate offline mode. Through the REST API, you can also make it available for others to see if the hackerspace is open or not. See working example on the website header at www.prishtinahackerspace.org

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
