Hi all,

I am in need of a circuit that can detect mating to another part.

Think door lock and keys, or party  favors... ??

It would be that one part would be connected to another of about 40 
possible combinatoins, and only if it is correct would the thing 
work.  say, light an LED or something.

I'm thinking when the two parts meet, they both light an LED to 
indicate the correct two were connected.

I am looking for someone who can lay out the curcuit, schematic, 
program the micro test it.

The probably power will a cell phone (or similar) battery.

And, no, I do not expect it will be free.

I can make my own PCB's, but if you need to that is fine.

any takers ?

I have some additional details, but that is the basic project.

if, you can't get my e-mail from yahoo, try
