Figured I should post it. You cant tell cause its dark, but is a platinum top with a black bottom.

2 blue LED's + a PulseVU 2x

I got a random pushbutton switch to control SW on the chip.

z0mG! nice!

how did you run it off the audio signal?

If you want to know more about it, Google is your friend.

As cool as the PulseVU is, you can do the same thing with a TIP-31
Or even a 2N2222 really...
Heck, an LM386 would do the job too.


Regardless, it's still a sweet mod SS

Edit:
For justice 'n' whatnot.
I figured, "hey, I got the stuff, why not?"
So, yeah, just made this.




Works like a dream!


I have to admit though, something like the PulseVU will ALWAYS have "smoother" results.
Still, I love doing it the 16 cent way

Yep. Does your 16-cent also have 16 different modes? Mine does.

Not yet

... You know, I ought to make a simple little program for a cheapo MCU (ATtiny2313 or PIC 12F629) that does that...
Try to make it use as few parts as possible.
If a did it right, I bet I could keep the cost under $5, put up the schematics/hex for free.

Ooooo I should do that....

You should.

Well, I looked into a bit...

The PulseVU is opensource.

You could make one for about $4.
