Hi Guys - scored a useful tool off fleabay recently an Elmo P10s - Document visualiser or camera.
Used £25 delivered. Works perfectly described in attached PDF.
Seeing Fred's document viewer gave me the idea.
Now no more tired eyes straining to see a schematic - Also useful as a low powered microscope for examining anything that's v.small - not just documents.
Actual size of the schematic was 6"x4" - 1st photo normal view - 2nd partially zoomed. No need for a computer just some sort of monitor.

There are many used ones available on the auction sites for not a lot of cash ;)
