Storage humidity and temperature monitor
Keep an "eye" on things that are best stored at a specific temperature and/or relative humidity.
by Dave Astels
Build a simple battery powered temperature and humidity monitor with a audio alert. This project uses the Adafruit Trinket M0 and Si7021 temperature and humidity sensor. A TPL5110 module provides battery management to ensure months of operation on a single battery charge.
Chilled Drinkibot
Make a nice, cold beverage using thermoelectric cooling!
by John Park
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.
Screaming Cauldron
This terrifying illuminated bowl will give trick-or-treaters quite a scare when they reach for candy and trip the distance sensor!
by John Park
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!!
Fiber Optic Whip
Dance in a Cloud of Fiber Optic Lights
by Erin St Blaine
Create a fiber optic whip that will inspire you to dance within a million points of light. The seven bright Neopixels inside allow for animation and infinite color combinations. The 3d printed handle is rugged enough for festivals and performances.
Adafruit Trinket M0
CircuitPython or Arduino IDE on this tiny little microcontroller board
by lady ada
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!
Pro Trinket Tachometer
Do you know how fast you were going?
by Bill Earl
Cutting tools and drill bits are most effective when run at the correct speed for the material. This simple project adds a precise digital speed readout to your shop machinery.
n3rfgun
Hacking the Nerf gun with NeoPixels
by Scott McCulley
We modified a stock Nerf gun to increase the firing speed, add multiple velocities for the dart, and blinky lights for more excitement in the dark!
Mystery Box: Shutterglass Chamber
Astound people with a mystery box that will reveal secrets hidden behind its transforming panels!
by John Park
Build this secret shadow box using LCD shutter glass panels, a Trinket microcontroller, and a healthy dose of mystery! The Trinket adjusts voltage to fade the panels from opaque to transparent -- all triggered by a hidden magnet sensor.

Fiddy - the FTDI Clip
With rainbow hair and pogo-pin teeth, Fiddy gobbles up FTDI
by Timothy Reese
Fiddy uses pogo pins and a spring to clip onto the FTDI pinouts on your board. No more soldering, or bulky header pins. Fiddy's FTDI FTW.
Tent Lantern
For when you don't want to go bump in the night
by Timothy Reese
When I'm camping, it's dark in the tent. I need a small lantern to gently light my tent, pack compactly, and recharge from a travel battery so I don't need to bring alkalines.
Mindfulness Clock OF DOOM
A grim reminder that time is priceless
by Phillip Burgess
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!

LED Campfire
Because it's not camping without a fire
by Erin St Blaine
Sit around this mesmerizing LED campfire and tell stories, sing songs and bask in its firey glow -- no lighter fluid required.
Adafriend the Virtual Pet Cube
Need a friend or a workbench buddy for long hacking sessions? Build one that responds to your interactions, sings, and shows emotion!
by John Wall
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!

Animated Flame Pendant
Turn on your heart light!
by Phillip Burgess
There’s no actual flame here, no heat…instead, LEDs and a microcontroller make a virtual flame that dances like the real thing.
Fair Weather Friend: Internet-Connected Migraine or Allergies Detector
"Web scraping" provides an alternative to restrictive programming APIs
by Phillip Burgess
Using forecasts by AccuWeather.com, this wireless ambient display predicts health issues like allergies or arthritis, or good days ahead for leisure activities like golf or sailing.
Trinket React Counter
Make a Physical Like Button
by Ruiz Brothers
Digital tally counter using a Trinket and 7-segment display.
Morning Star POV Double Staffs
288 points of twirling, programmable lights
by Erin St Blaine
Remote-controllable twirling double staff batons create a mesmerising light show. Upload your own logos, patterns, or pictures. An IR remote control lets you easily change pattern, brightness, or speed.
Talking d20 20-Sided Gaming Die
“Greetings, adventurer!”
by Phillip Burgess
The 20-sided die — or “d20” as it’s known to tabletop gamers — is an icon of geek culture. We’ll 3D-print a jumbo d20 and outfit it with electronics to announce your rolls (and a few surprises).
Galaxy Pendant
Wireless charging and rugged indestructibility in a beautiful little glowing pendant

Genesis Poi: DotStar LED Persistence-of-Vision
High tech, all-season, water- and playa-resistant poi that you can build and customize yourself!
by Phillip Burgess
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.

Bluetooth-Controlled NeoPixel Goggles
Adding a smartphone interface to your wearable project couldn't be easier!
by Phillip Burgess
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.
Really Simple Animatronic Tail
A single servo, a little math…let the wild rumpus start!
by Phillip Burgess
Bypassing a lot of the mechanical engineering typically required of animatronic creations, this project works with gravity (rather than fighting it) to create a wagging costume tail. Thank you Galileo!
