Some of the most satisfying projects of all are the ones that do something visual. All the network routers, data loggers, and thermostats are great. But we are visual creatures and even a humble blinking LED is enough to give you a little rush even compared to finding a large prime number. We wanted to see what our community could do visually with a Raspberry Pi so we challenged you with the Visualize it with Pi contest.
As always, the competition was brisk, with a lot of great projects. This contest showed off the trend towards using LED modules and assemblies to add visuals to projects. Why not? They are cheap enough and a well-integrated module can make a project simple to wire and integrate.
We didn’t see as many media-related projects as you might expect, although there was one tied into Stranger Things, one to Tron, and the virtual reality lighting project did have some Star Wars images. Projects ranged from the practical storage box labels to the whimsical lemonade bottle that strobes to the beat of the music. If none of that is hardcore enough for you, there was even a Raspberry Pi-controlled radio telescope. You can find all the entries over on Hackaday.io. Now let’s see which entries managed to turn the head of the judging panel.
You can plug in a Raspberry Pi, and you can blink a LED. You can visualize data, and now there’s a contest on Hackaday.io to show off your skills. Right now, we’re opening up the Visualize It With Pi contest on Hackaday.io. The challenge? Visualize data with LED strips and panels. Is that ‘data’ actually just a video of Never Gonna Give You Up? We’ll find out soon enough.
The goal of this contest is to combine a Raspberry Pi and its immense processing power and the blinky goodness of LED strips and panels to visualize and interpret data in novel and artistic ways. We’re looking for animation. clarity, and flamboyant flickering. Want some ideas? Check out the World of Light or the American Constitution Candle. We’re looking for the most blinky you can do with a Pi, and yes, there will be prizes.
Prizes for the best blinky include, of course, more blinky. The best visualizations from a directly connected sensor, data from an Internet Source, and data from an esoteric data source will each receive some Blinkytape. This is a strip of WS2812b LEDs with an ATMega32u4 embedded on the end. Plug a USB power supply into the Blinkytape, and you get a strip of LEDs in whatever color you want with the ability to push animation frames to the chip on the strip. The Grand Prize winner for this contest will also receive Blinkytile Explorers Kit, a Serpentine LED strip, a LED ring, and two meters of ultra thin LED strip.
Let’s Do This!
The requirements for the contest are simple: just use a Raspberry Pi to drive LED strips or panels, post it as a new project on Hackaday.io, and submit the project to the contest. We’re looking for a full description, source, schematics, and photos and videos of the finished version of the project — do everything you can to show off your work! The contest is open right now, and ends at 08:00 Pacific on October 1st. We know you like to blink those LEDs, so get crackin’.
