Nigel Goodwin said:with such a low level of electronics knowledge
Disclaimer: I am not upset... the quoted comment was based on my post, but I would just like to clarify so that any further help I recieve will be given in the correct context (that I am not absolutely cluleless
I have a degree (B.S.) in computer systems and electrical engineering where my primary focus was on the computer side so my analog electronics skills are lacking, but I would not consider myself having a low level of electronics knowledge. My 'resume' includes an NTSC signal generator and a complete web, telnet, and ftp server implemented on an AVR... This is not meant to 'wow' anyone as I'm sure what took me months you guys could do on a rainy Sunday afternoon, but I think it at least puts in perspective where I stand.
Now for the fun stuff... Since I apparently meet all the requirements for a project bound for failure I am going to post my circuit/application and I am seeking feedback on any/all aspects.
Application Description:
-We have a matrix of bins (in the case of the schematic 3x2=6 bins -- but this could be expandable too 50x50 if need be).
-Each bin can hold zero or 1 object at any given time
-There are 300 hundred objects, but only 30 unique types so duplicates are available
I want to be able to identify which object is in which bin when a button is pressed.
Schematic: **broken link removed**
The schematic shows Row1/Column1 'On'... So essentially I am reading what is in bin1. Bin2 is an empty bin.
I added the diodes because I dont want the current represented by the red line in the schematic.
Hope this is clear now and I do appreciate your help, even though I disagreed with the approach I do believe you guys are well intentioned and here because you enjoy solving problems and helping others.

PS Philba, I am in Seattle too.. Well Kirkland.
