If you have a Raspberry Pi connected to an LED matrix, you might think about creating a simple oscilloscope. Of course, the Pi isn’t really well-suited for that and neither …read more Continue reading Building the OhSillyScope
Flashing LEDs are all well and good, but they’re even better if they can sync up with ambient sounds or music. [mircemk] has built the LUMAZOID visualizer to do just …read more Continue reading An Easy Music Visualizer With the Arduino Nano
Winamp eat your heart out, because thanks to the Microsoft Kinect in the hands of [Samarth] there’s a new way to make your screen dance along with you. He created a music visualizer demo that takes advantage of the 3D depth camera on Kinect by outputting a fun pixelated silhouette and color changing strobe. When there are big high-hat hits or bass thumps the camera feed reacts accordingly (as any good visualizer would). He even uploaded his code for the project just in case anyone would like to take a look at it.
The visualizer utilizes the OpenKinect-Processing library which …read more

One reason we really like [Rulof]’s hacks is that he combines the most unlikely things to create something unexpected. This time he makes a fast-moving loop of cotton string undulate in time to music.
To do this he uses cotton string, hard drive parts, two wheels from a toy Ferrari, two DC motors, a plastic straw, a speaker, and an amplifier. The loop of string sits in the air by being rapidly rotated in between the two wheels. The hard drive parts, driven by the amplifier, give the string a tap with an amplitude, and at a time determined by …read more
What to call this LED strip music visualizer is a puzzler. It lights up and pulsates in time with music similar to the light organs of 1970s psychedelia fame, but it’s more than that. Is it more like the Larson Scanner that graced the front of [David Hasselhoff]’s ride on Knight Rider? A little, but not quite.
Whatever you decide to call this thing, it looks pretty cool, and [Scott Lawson] provides not one but two ways to build it. The business end is a simple strip of WS2812b addressable LEDs. It looks like the first incarnation of the …read more

Usually, when you think of driving a VGA–in software or hardware–you think of using a frame buffer. The frame buffer is usually dual port RAM. One hardware or software process fills in the RAM and another process pulls the data out at the right rate and sends it to the VGA display (usually through a digital to analog converter).
[Connor Archard] and [Noah Levy] wanted to do some music processing with a DE2-115 FPGA board. To drive the VGA display, they took a novel approach. Instead of a frame buffer, they use the FPGA to compute each pixel’s data in …read more
