LED Organ [simple analog electronics project]

Friday, February 24th, 2012

Recently I’ve gotten interested in playing around with, and learning about analog electronics. This is an outgrowth of my existing passion for physical computing prototyping using the Arduino platform. So I did some research on the Make:Project website and found a few simple projects to kick-off my exploration.

For a long time I’ve had a passion for both music and lights, so I decided to start out my exploration of analog circuits with a simple LED organ project that provides me with a new way to link these phenomena. The project that served as my inspiration is called Wearable LED Organ, though my version was just built on a regular breadboard and is therefore not really wearable. Here is a short video of my breadboard prototype, please ignore the Arduino in the background because it is not connected to the circuit.

Now that I have this project under my belt, I want to take it to the next level. My plan is to create two new versions of this project: (1) I want to create a smaller version of this project that goes towards the wearable side of things, but that is more wearable than the original project featured on the Make site; (2) I want to also create a larger version of this project that incorporates band pass filters so that I can have different sets of leds responding to different frequencies.

Here is a video of a project, also from the Make site, that does something similar to what I have in mind for the large LED Organ. Another thing that I like about this video tutorial is that Collin Cuningham is about as fanatically organized with his soldered breadboard as I am. I just love it. Go Collin!
