A couple of years ago, many of the electronic junk stores in the San Fran. area were selling old Sony viewfinders. These are 1" monitors that take a standard video signal, and run off a nine volt battery at about 100ma! Neat toy. Mine cost about $17. The only catch is that the picture is inverted. Anyhow, I'm sure it would be easy to use these for your purposes... Paul H.
