Does anyone have a few Atmel/Quantum QT301 capacitance2voltage ICs I 
could buy? I could really use 3 of them. Willing to pay extra to make it 
worth your while. Hoping to find something in the next few days.

If you haven't heard of the ATMEL QT ICs you should read about them. 
Really cool stuff, and super easy to use.

  They produced one a few years ago that output a varying pulse width 
dependent on proximity. basically a proximity to voltage converter. It's 
the QT301. I've done a LOT of searching and can't find any! Digikey had 
them but their are none in stock. I seriously doubt they will get any 
more since it's a discontinued item. Still waiting to hear back from 
them. I'm looking into larger discontinued IC distributors but they have 
pretty high min orders. Maybe I'll organize a group buy. The musical 
applications for this chip are huge.
Here's the spec sheet:

here's a video showing how simple it is.
