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.
Adafruit’s PiTFT displays link to the Raspberry Pi’s GPIO header instead of a video port, making them compact & ideal for portable projects. But this connection normally limits them to a subset of specially-compiled games and emulators — high-performance OpenGL-based games were previously incompatible. New software now makes gaming more practical on these tiny displays!
For transit-bound people, NextBus — a free internet service providing arrival data for over 135 transit agencies — is a tremendous convenience. Knowing when a bus is due means less standing out in the rain…one can use that time inside to get a little extra work done, or finish that cup of coffee. Using the Raspberry Pi computer, we’ll create a dedicated NextBus “appliance” that informs at a glance.
NeoPixel LEDs are the bee's knees, but in a few scenarios they come up short…connecting odd microcontrollers that can’t match their strict timing, or fast-moving persistence-of-vision displays. Adafruit DotStar strips deliver high speed PWM and an easy-to-drive two-wire interface, bridging the gaps in the spectrum of awesome.
Traveling or on the road, sometimes finding an open network to get online and finish a job is more important than lunch or a nap. MASLOW (Mini Adafruit System Locates Open Wireless) is a tiny battery-powered WiFi detector with a 3D-printed enclosure…assemble one yourself and clip it to your laptop bag.
What your new apartment really needs is an upgrade to that beaded curtain - why not liven it up with a massive 1,500-LED NeoPixel curtain? NeoPixels + Raspberry Pi + Fadecandy == AWESOME! This project will show you how you too can build this massive and enjoyable flexible display. If you're interested in any other kind of large-scale NeoPixel project, this guide will help with all your detailed questions with Phil Burgess' hard-earned tips and techniques.
Made of crystal-clear acrylic, this case keeps the Pi secure, has a hinged top for connector access, and even has little feet cut into the sides so that it stands up above your desk. You can use all of the connectors on the edges of the Pi: HDMI, Audio/Video, microSD slot, micro USB power, Ethernet and the 4 USB ports. There's also a cut out to allow a 40-pin IDC cable to the GPIO breakout pins.
Build and customize your very own open-source button grid controller. This DIY kit comes with delicious translucent button pads, driver boards, diffused white LEDS and a custom laser cut enclosure. The result is a sturdy and elegant but also super-hackable controller device for music, video…or something else???
Adafruit’s Bluefruit devices are hands-down the easiest way to get Arduino communicating over Bluetooth. Taking inspiration from the helical Guggenheim museum, this project coils a contiguous reel of NeoPixels around a dapper top hat to create a wearable scrolling message display you can control with your iOS/Android phone or tablet.
