I was looking around for a good solution for the mixer I'm building's level display, and I stumbled accross this little beauty:

This is an IC that you connect 10 LEDs to, and then it lights them up sequentially based upon a given signal, low, and high voltage. Definitly useful in my case, and could have some cool applications.
Checkout the schematics of the infinitphase at my site (prophecysound.com) for one way the 3914 can be used.

Yeah, I saw some of those schematics around the same time, maybe it was subliminal inspiration, heheh.
Yeah, the LM3914 rocks my socks. Really good for making anything sort of voltage into light and thus into resistance.

I played with those. Fun stuff. You can also use a bunch of comparitors with the inputs wired in series and the outputs in parallel. Cheap and easy voltage display.
