To most of us, fractals are simply fairly patterns. However the mathematicians know what’s up: fractals are fascinating. They repeat endlessly, with solely a change in scale. There are a lot of mathematical features for producing fractals and their output variations are virtually infinite. If you happen to perceive the underlying math, the crystal-like progress of fractals can grow to be mesmerizing. To make sure that they at all times have new fractal artwork to be mesmerized by, Runezor constructed this system referred to as PiArtFrame.
Because the title implies, this can be a Raspberry Pi-based system that exhibits artwork in a body. It’s particularly attention-grabbing as a result of it shows fractals on an ePaper display screen. That is cool as a result of it attracts little or no energy over time, and since the very excessive distinction makes the fractals look extra “actual” in comparison with in the event that they had been proven on a conventional LCD. The ePaper display screen sits inside an image body, so it seems like a printed piece of artwork and never a digital show.
The 2 key elements of this mission are a Raspberry Pi Zero (or Zero W, or Zero W 2) and a 7.5″ Waveshare ePaper display screen with a Raspberry Pi HAT controller. The performance is all due to a Python script that takes benefit of some libraries. The primary merely handles drawing graphics onto the ePaper display screen. The Pillow library generates these graphics primarily based on math carried out by the numpy library. Runezor even hyperlinks to the body they used, which is on the market on Amazon for anybody that wishes to showcase their very own fractals.
If you happen to’re a fractal-loving math geek or simply assume they appear good, then PiArtFrame could be an ideal weekend mission.
