Ok I have an idea for a case mod, but I think I need some help on it. I am an electrical engineering student, so this should be well within my abilities, but it would be nice to get some input on the idea, or if anyone knows of anyone else having done this, let me know.
I was thinking about my SB Live! Platinum, when something hit me. I am using the digital connection for my speakers which leaves me a pair of analog out spots on my sound card. So I thought wouldn't it be neat to make some sort of spectrum analyzer/vu meter with the analog outputs on my SB live. Here is what I am thinking of doing.
First I will have to amplify the signal from the outputs. Probably using a 741 opamp. Then I need to run the signal through 3 filters. High pass, low pass, and mid range, to split the signal. Then probably another amplification on each of the three resulting signals, and finally feed the remaining signals into three bar graph leds. This way anytime my sound card was outputing sound, you would get the neat moving lights. I have a rough schematic drawn up for it, but I would like someone who knows what they are doing to help with the design. The bar graph led's would of course be mounted in a 5.25" drive bay. I was thinking two identical setups. One for the front dignal and one for the rear. So 6 bargraphs in all. Of course if you only have a single analog output it could be done just singley. If anyone is interested in this project, email me at nheinric@d.umn.edu. I would really like to get started, but need some help. This would be the altimate addition to your case!!
