Once you’re done with this, you could try auto-dimming your keyboard backlight. You’ll need the Razer SDK to get started, and you can get the other ingredients from ’s repo. As points out, this is just the beginning of what the plugin can do. uses some of the 10 programmable keys to change colors on the fly, and the result is pretty awesome. It does what you might expect-reads the visualization values, sets them up for display on the trackpad, and renders them to said trackpad. ’s hack is built on the Tin圓D visualization framework. He made himself this sweet audio visualizer for it that extends Winamp visualizations to the Switchblade UI. ![]() has such a keyboard: the Razer Deathstalker Ultimate which features the SwitchBlade UI. There aren’t any blank keys to override, and there sure isn’t a full-color trackpad that you can write apps for. This build is best explained by watching, so check out the video after the break.Ĭontinue reading “Dancing Mandelbrot Set On A FPGA” → Posted in FPGA Tagged audio visualizer, cyclone iv, fpga, fractal, mandelbrot setĪs much as we like a good clean Model M specimen, those curly-corded clicky behemoths are somewhat lacking for certain flavors of gaming. A Fast Fourier transform decomposes the audio input into frequencies, which are used to control the colors of the output image. On the FPGA, a custom calculation engine, running at up to 150 MHz, does the math to generate the fractal. An audio input maps to the color control, and a VGA output allows for the result to be displayed in real time. On the input side, UART or an IR remote can be used to zoom in and out on the display. ![]() The Terasic DE2-115 development board, which hosts a Cyclone IV FPGA, provides all the IO and processing. The build produces a Mandelbrot Set with colours that are modified by an audio input. Dancing Mandelbrot Set uses an FPGA and some math to generate a controllable fractal display. This FPGA based build creates an interesting display which reacts to music. ![]()
