From the Forums: Adafruit-Blinging a Flashy Pinewood Derby Car
eagleeye2e shared a how-to for bringing some Adafruit interactive bling to his son’s Pinewood Derby car on the Adafruit Forums:
We decided to add a little high-tech flash to my son’s Pinewood Derby car this year. This project involved several Adafruit products including a 3.3v Trinket, a NeoPixel stick, a FLORA Accelerometer/Compass Sensor, and a Lithium Ion Polymer Battery. All of these components were chosen for their size and their light weight. The idea was to have a subtle yellow glowing effect under the car while it was at rest and while the car was in motion going down the track the pixels scroll from front to back with a brighter, different, color. The faster the car goes, the faster the pixels scroll. In addition, every time the car goes from scroll to rest, the color of the scrolling pixels changes to a new color for the next race. The car received many complements and oooh’s and ahhh’s. Thank you Adafruit for all of the great products that allowed us to add something fun and unique to our Pinewood Derby experience!
Adafruit Trinket – Mini Microcontroller – 3.3V Logic: Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, 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 arduino-IDE programmable board!

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
