Re: Re: [sdiy] Touch Controllers

I saw that webpage, or if it's not yours, about the same thing. Very 
interesting.
Later I checked resistance of data storage tape. Old type
3M I guess, small tape 20GB capacity. And for about a meter
of length it showed about 20kohm. Pretty nice.
How about using really old tape from those big memory units
seen on every movie older than 10 years. They were thick
and durable.

BTW, my local electronic shop has touchscreens. Small glass
plate covered with XY resistive films. Size for about 5''
LCD. It cost 4EUR.
