Make Magazine Pixelmusic 3000

I'd like to read the article, but $25 for the digital edition? Gosh. makezine.com/14/pixelmusic/. Looks like a music visualizer. Did they really need an ADC for the project?

Well, if you live near a bookstore that sells the magazine, it is on the shelves right now...

I do not see that it is very difficult to recreate something similar, you can use any TV Text object with some block character... a sigma-delta ADC and some testing of effects...

The thing in Make is like "Atari Video Music" from the early 1970's which does this:

It's like VU/dB meter lights except it's 2 dimensional and changes color,
and also resembles a 1970's style "color organ" but with awfully low resolution graphics.
Groovy visualizations for that new 8-track tape player.

They give you access to the spin code on that page, no need to recreate.

Why can't they do the ADC on the prop with a few discretes? The mic on the demoboard just needed a decoupling cap. The audio demos in the propeller tool have 10 bit resolution (I believe), which should be good enough for a project like this. Maybe I'm missing something...

I think just because it was very easy to get matched stereo inputs by adding that one ADC chip.

I converted this for the demoboard, if you're interested. Not a very elegant hack, but it works.

Concentrate on understanding the problem, not applying the tool
