Alright, so I had some post-publication weirdness following my last post, and it took me a few days to figure out exactly what was up, but I think I finally have all the details, and I learned a lot in the process.
So, this is a project that was nearly a month in the making. I set out to make a sound-reactive EL panel but found that driving EL in such a way is actually kind of difficult. If you've been following the blog, I've been working on this project in one way or another since my transformers article, and it's actually the reason I wrote that article.
Again, a disclaimer. There are over 8,000 words in this post that document all of my design decisions on this project. It is not a how-to guide, but if you have some background in EE, I hope that you gain something from it.
Without further ado, let's get down to business.
