Light painting, or taking a photo of a moving RGB LED strip with a extremely long exposure, is the application du jour of Arduinos, photography, as well as bright, glowey, vibrant things. Hackaday alumnus [Phil Burgess] has come up with the very best tutorial for light painting we’ve seen. It’s such a great setup, it can be utilized to produce animated .gifs utilizing several camera exposures.
The develop utilizes an Arduino Uno, SD card shield, as well as Adafruit’s new NeoPixel strip with 144 RGB LEDs per meter. in spite of a potentially significant mess of wires for this project, [Phil] kept whatever very, extremely neat. He’s utilizing an Altoids situation for the ‘duino, an 8 AA-cell battery holder as well as 3A UBEC for the power, as well as a wooden frame constructed out of pine trim.
Part of the art of light painting includes a great deal of luck, exponentially so if you’re trying to make a light painted animated .gif. To solve this problem, [Phil] came up with a extremely clever solution: utilizing a rotary encoder connected to a bicycle. With the rotary encoder pressed up against the wheel of a bike, [Phil] can get a extremely precise measurement of where the light strip is along one dimension, to ensure the right pixels are lit up at the right time as well as in the right place.
It’s a wonderful build, as well as if Santa brings you some gift certificates to your preferred electronics retailer, we couldn’t believe of a much better method to bring animated .gifs into the genuine world.
