Cy-Visor Basics

The Cy-Visor (i-Visor) is a 800x600 color microdisplay system that supports VGA, NTSC, SCART, and composite video. This display is a sequential color display. This means that the microdisplay is lit with a specific color (magenta,green,blue) in sequence.

Cy-Visor Hacks

The field sequential color display has been a hinderance to creating a covert display. However, there has been some very possitive advances.

FreemanPascal (05/12/2002) - I own two of these units and have been generally happy with the quality of the images. I have hacked one of my units into a monocle (the other was purchase as a monocle). My only complaint is that the cable connecting the control unit and display uses a a very fine gauge of wire that hasn't proved to be resilient enough for everyday use. With both units, my cables have had broken conductors at either end. - YMMV.

FreemanPascal (05/12/2002) - While attempting to repair my damaged display cables, I discovered a neat technique for exposing the individual conductors of the cable. Bringing the end of the ribbon cable to the heat from the tip of my solding iron caused the insulation to shrink back, revealing enough length for securing to the connector. All other attempts at prep'ing the cable failed miserably and used nearly an inch of cable in the effort.

FreemanPascal (08/15/2002) - Forgot to mention that I have gotten confirmation from Daeyang that the 4400 unit will run fine from a 12vDC feed to the input jack. I have been running mine like this for several months without any problems. I can produce the message from Daeyang if anyone is interested.
