Collaborate Disseminate
[ExtremeElectronics] cleverly demonstrates that if one Raspberry Pi Pico is good, then nine must be awesome. The PicoCray project connects multiple Raspberry Pi Pico microcontroller modules into a parallel architecture …read more Continue reading Parallel Computing on the PicoCray RP2040 Cluster
You’ve probably heard it said that clustering a bunch of Raspberry Pis up to make a “supercomputer” doesn’t make much sense, as even a middle-of-the-road desktop could blow it away …read more Continue reading Learning the Ropes With a Raspberry Pi Mandelbrot Cluster
The Mandelbrot set, according to Wikipedia, is “the set of complex numbers for which the function does not diverge.” Even if you don’t understand the mathematics behind it, you’ve likely …read more Continue reading Zooming Through the Mandelbrot Set On An Atari
In an announcement that came as a surprise to few, NASA now says that landing humans on the Moon by 2024 is no longer likely. Acting administrator Steve Jurczyk lays the blame at the feet of Congress, for failing to …read more
The Mandelbrot set is a curious mathematical oddity that, while interesting in its own right, is also a useful tool for benchmarking various types of computers. Its constant computing requirement when zooming in and out on the function, combined with the fact that it can be zoomed indefinitely, means that …read more

Over on GitHub, [ttsiodras] wanted to learn VHDL. So he started with an algorithm to do Mandelbrot sets and moved it to an FPGA. Because of the speed, he was able to accomplish real-time zooming. You can see a video of the results, below.
The FPGA board is a ZestSC1 that has a relatively old Xilinx Spartan 3 chip onboard. Still, it is plenty powerful enough for a task like this.
The project doesn’t directly drive a display. It does the math, stores the results in the board’s onboard RAM and then sends a frame to the PC using the …read more
The Mandelbrot Set is a mathematical oddity where a simple function creates an infinitely complex landscape that you can literally zoom into forever. Like most people, I’ve downloaded Mandelbrot set viewers and marveled at the infinite whorls and spirals, and then waited while each frame took minutes or hours to render as I zoomed in. [Michael Henning], [Max Rademacher] and [Jonathan Plattner] decided to throw some modern computational muscle at this problem by building an interactive Mandelbrot set viewer using a laptop and two FPGA boards.
The three are students at Cornell, and this was their final project for the …read more
