We’re lucky enough to have two teenage boys in the house. One of them lurks in the gloom of his bedroom listening to loud, raucous music and doing god knows what on his computer until he can be lured out by offers of food. But sometimes the music is so loud, or the headphones so firmly clamped that he doesn’t hear the call of “Tea time!!!” wafting up the stairs. I could go up to his room to get him, but this is the 21st century and there has to be a better way.
That better way is the Tea Time Klaxon.
Now I just need to send a tweet featuring the secret hashtag to trigger flashing lights and a buzzer to alert the eldest that tea is ready.
Actually, I’ve wanted to find an excuse to make something with one of these LED towers for ages, because they just look so cool, and recently they’ve been discounted at Pimoroni which gave me a good excuse to get one. The tower needs 12v DC so you can’t drive it directly from a Raspberry Pi. Instead I bought a power supply from Amazon – this one, I think and a Pimoroni Automation pHat to handle the switching.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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
