Hello I am a repair tech for medical equipment and am needing to make sometest boxes for simple location of the number of a wire that has beencut off in a harnesses with as many as 256 wires in them.These harnesses have a plug on one end and the cut-off unlabled wiresat the other end . Up untill now I have used what is called a "lightbox" these boxes have a plug to plug the harness into.. 128 or 256ledson them and an internal battery and a lead so that when you touch oneof the wires with the lead one of the leds will light showing which pinon the plug is associated with that wire (each wire is then labled)Now with what I would like to build.Since you have to look at these wires through a microscope it is verytime consuming to look up from the scope to see the led every time.What I would like to do is replace these leds with something thatannounces the number like "21" "102" "128" etc. with a voice thiswould make labeling much faster.Does anyone know of a pre-made IC? or EEprom? that would have 128 or soindividual areas that could store the voice message for the number andbe random accessed. would it need some sort of special trigger? As imsure you can tell my knowlege is limited in this area, I am juststarting to work on this project and anyones ideas would be greatlyappreciated.
