Music Visualization Generator With A Propeller

May 9, 2012 by Brian Benchoff 4 Comments

The folks over at Gadget Gangster have been working on a music visualization system using a Parallax Propeller. The visualizations are awesome in their early-90s demoscene way, and of course we love anything using the oft under-appreciated Propeller.

The project is called Video Beats and it generates music visualizations in the style of a blocky but very complex Atari 2600 game. There’s really not much to the build – just two RCA jacks for the audio input and video output along with a couple of resistors – but we do appreciate how nicely this project would fit in at a chiptunes show.

The Gadget Gangster team says the input isn’t limited to just audio – a potentiometer, accelerometer, or even a light sensor can be added to the build for a more dynamic output. After the break, you can see the demo of Video Beats, and a [Family Sohn] music video that used an early version of this circuit.

Wiimote Controlled Ruben’s Tube

June 11, 2010 by Jakob Griffith 13 Comments

While we could be content following our “kiddie d-day” as [Caleb Kraft] suggested. We know you can’t continue such an awesome Friday without trying to blow yourself up first.

This Wiimote Rubens’ tube caught our eye. A PVC Aluminum irrigation pipe is drilled with holes and propane is pumped through. A speaker on one end creates changes in pressure and a neat light show follows suit. [ScaryBunnyMan] went further though, with a collection of software and a Wii Remote he “plays god” controlling the music, and thus, the fire. Check out a fun video after the split.

Orientation Aware Camera

October 23, 2008 by Eliot 27 Comments

[Andrew Magill] just added his Orientation Aware Camera to the Hack a Day Flickr Pool. It uses a 3-axis magnetometer and 3-axis accelerometer. He didn’t want to spend too much effort on the USB side so he picked up USBMicro’s U421. It’s a fairly well documented preprogrammed microcontroller for USB. He later regretted this; his final sample rate was only 5Hz because of all the overhead. Using the positional data the, webcam image can be corrected for any sort of shaking. [Andrew] took this one step further by using OpenGL and stitching all of the video frames together live into a full panorama. Be sure to watch his excellent video demo embedded below.

[Peter Kirn] from Create Digital Music has an article up highlighting many of the great music and visual performance pieces planned for The Last HOPE on Friday night. If you are around New York and not accustomed to hacking conferences, this could be a great excuse to go check it out. Here are some of our favorite projects.

Pulse, The Emotional Visualization Organism

July 7, 2008 by Juan Aguilar 4 Comments

[Markus Kison] built a device called Pulse, which is part art installation and part data visualization tool. What the emotional visualization organism called Pulse actually does is scan new posts on Blogger.com blogs for synonyms of keywords related to 24 distinct emotions from eight emotional groups. A red cone in the center expands when keywords are detected, in effect acting as a mood indicator for Blogger.com blogs.

The 24 distinct emotions are based on [Robert Plutchik]’s psychoevolutionary theory of emotion, and the device itself is built from a glass case, various servo motors, and custom controller for the servos. This is a compelling idea, but we wonder whether it scans for modifying words or just the keywords alone. It wouldn’t make a lot of sense to have the sadness region expand drastically if many people simultaneously post the sentence “I’m not sad at all.” Video embedded after the break.
