I'll keep that in mind, as long as they are less than 5 years old, they should be self contained like this one.
Here's a couple of progress photos... have removed the little lens cover and you can see the USB chip (Vimicro VCO363) and the CMOS sensor (I was mistaken, it is only 1.3MP) and how the project is going together.
My plan is to find a black tube large enough in diameter to slide the sensor section into (more support) and cut out a section for the sensor to see through. This will all then slide into hoel drilled in the side of the EP body. I can the align both focal plane and centre (provided I get the hole through the EP body in the right place :-) ). Then epoxy it in place.
Should be able to perform a functional test tomorrow night once I finish the connections. That will then determine if I need more test subjects...
