Hi All.

Is anyone interested in coming to UCC to design a Note reader for  
dispense, I have a few ideas in mind on how to do it but require some  
assistance.

Anyone Keen for later today or tonight?

Idea:
Grid of 6~ LDR's with white light on base projecting thru note,  
Depending on the amount of light received on the flip side determines  
what note it is, Its Sorta foolproof as Plastic/Paper will allow  
more/less light through. And a small motor to pull the note in/out,  
PIC or AVR to check the light levels of each LDR.

Pretty simple really...
