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!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
