I have stumbled upon this page
http://www.matrixorbital.com/products/lk202-24-USB.htm
they are selling 2 line 20 charachter/line LCD displays that connect to USB.
Has anybody tried making the interface themself? If i just buy a display is it hard to connect it to pc through USB? Are there any web pages that describe how to do it?

Thank you,

Boris.
