Peltier cooler + Trinket M0 + CircuitPython = refreshing drinks! This project uses a thermoelectric cooling assembly to turn electricity into coldness!! That chill is transferred to your beverage of choice via thermal conductivity, and then transported safely to your drinking glass with a peristaltic pump. Ahhhh.
An IR distance sensor, Trinket M0, NeoPixel strip, and AudioFX sound board plugged into powered speakers combine to make a booby trapped candy bowl. The CircuitPython program measures the distance of objects in front of the IR sensor, and changes the LED colors to match. Then, when you get too close, it screams bloody murder!!
The Adafruit Trinket M0 may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. It's our lowest-cost CircuitPython programmable board!
It’s not pleasant thinking about one’s mortality, but that’s the point of this project: to make one aware of the passage of time and how precious each minute is. As you look at the clock, remember that you are never getting those minutes back. Stop watching internet cat videos and make the most of them!
In this Pro Trinket powered project, build and 3D print yourself a friend, an Adafriend! This little colorful guy with an eye responds to taps and vibrations, and shows emotion on its little LED matrix face with a sad, neutral, happy, or angry face. It plays tones that correspond to it's emotional state, and even sings some recognizable tunes and themes when it's in the mood! If left alone for too long it gets lonely, but pester your pet too much and it may get angry at you! Build yourself an Adafriend and keep it happy to sing along with the coolest cube around!
Persistence of vision (POV) is the illusion of a solid image where there is none — a task for which LEDs and microcontrollers are a natural fit. Poi is a performance art of spinning tethered weights. Some of the most dramatic performances use fire poi! We sought to create something with that level of “wow,” but safer and usable indoors or out. And so these “Genesis” POV-poi were born.
Incorporating Bluetooth in a project no longer requires the most advanced microcontroller or lots of code…our Bluefruit LE UART Friend and accompanying app for iOS and Android make it easy! Building upon our popular "Kaleidoscope Eyes" NeoPixel goggles project, this guide shows how Bluetooth LE can be used even with the most modest setup.
