[sdiy] A little OT, Begging a hand

[Alwyn Lloyd]

Hi All,

The PAIA ribbon controller circuit allows detecting of two touches by 
using a constant current through the ribbon.

http://www.paia.com/ProdArticles/dual-ribbon-howto.htm  is the article
the section is the "2 CVs from one ribbon"

Is this an option?

It is made up of two resistive lines that are bridged by a resistive layer that changes based on pressure. Currently I can sense the position and pressure of a single touch but during use I noticed that with two touches, the results *looked* like I might be able to resolve both touches and hence I have been digging into it.
