Hackers in Residence: The Sound Visualizer Pt. 2

May 7, 2015

An addition to a previous project, this time using a PC and a custom Java app to create your own music visualizer using a RGB LED matrix.

Hackers in Residence: The Sound Visualizer

March 23, 2015

A fun project that uses a Raspberry Pi and a custom Java app to create your own sound visualizer using a RGB LED matrix.
  • I bet it is Robert C too

  • End to end this is a great project for taking old technology and puting a new spin on it.

    I really like the built-in lighting. Keep up the good work!

  • Nice stupidity, man! (I never thought saying that would be a ‘nice’ thing.)

    I am interested in an unpopulated Pro Micro-ATX boards and a handful of “expansion cards” left over that you mentioned.

  • Doh! My mild dyslexia kicked in pretty hard here. I thought the title had ‘fidget spinner’ in it.

    Any who, nice project and go sport ball!

  • I wrote a desktop Java application that works with the DRV2605L to help preview the different vibration patterns mentioned in the datasheet. It can queue up to 7 patterns for sequential execution.

    It communicates with the Arduino over serial communication, so you need RXTX for Java to get going.

    Here are some links to the source code and executable, for those interested:

  • Congratulations on your new role, Feldi!

  • Here is a video of the project we made for our high school that uses this product. The EL sequencer is running the code linked below with the blue chasing EL wire (the plum on the knight’s head).

  • I love the little robots from “*batteries not included”.

  • Here is a link to the source code for chasing/flowing EL wire, using this sequencer: https://github.com/onebeartoe/electronics/tree/master/el-sequencer/chasing_el_wire

  • Yep. That was the plan, if there is no source code available that demonstrates how to use this with the pigtail (https://www.sparkfun.com/products/12934). Thanks, anyhow! I’ll update if I figure out the sequence to make it look like the EL is chasing.
