Yes it is cool. Take a handful of components and some el wire. You attach it to an Android phone. Presto, you have a light show. Everything in-between is pure inventiveness.
I like this idea and think my grandson and granddaughter would like it, too. They're too young to have a cell phone, but we have lots of CDs around. Worth looking into, as long as I can buy some of the EL "wire."
I just checked for EL-wire suppliers and found many on Amazon that sell this product in a variety of colors and lengths for less than $10. Some of the packages include a power supply that takes AA or AAA batteries. Heck, I might even get some for my lab. Search Amazon for "electroluminescent wire," but without the quotes. Happy shopping.
I saw that, too, Jon, where Google points to places you can get incredibly inexpensive EL panels. It made me vaguely recall when EL panels were a big deal in the early 1970s, in Popular Electronics. That's what I thought and when I did a search, it turns out I was correct. Here's a 1984 EL panel patent, which references a 1971 Popular Electronics article on an El Panel Driver.
Interesting, Alex. I think GE produced EL night lights back in the '70's and they glued a penny to each cardboard package, because the company claimed it would only cost one cent to run the nightlight for a year. I haven't seen those night lights in years. The ones on the market now probably use LEDs. At night there's enough light from LEDs and vacuum fluorescent displays in our kitchen, family room, and bedrooms to make navigating easy. I wonder how much electricity these always-on displays and indicators waste.
EL wire is quite a lot of fun, you can put it in just about anything and it bends and flexes with ease, come low quality wire will not hold up to repeated bending so beware but i have a better example of the flexablility of the wire http://katzmattcreates.tumblr.com/post/18450285546/katzmatt-diamond-minecraft-head-done this is my blog of some of my other creations
There are people like me who love the peace and quiet. Maybe I could enjoy sounds without having them destroy my peace and quiet. You've got the beat and volume showing, now flash in the words with the proper "tone" showing. Then "sparkle" in some over/under tones. Interesting.
Andrew Morris designed a circuit that could detect a stroke victim's groan and convert the sound into a signal so caregivers would know when help was needed.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
