I am interested in doing some hardware projects with my enhanced Apple //e...is
there anyone around who has had experience with the innards of a //e and can
offer some suggestions? Maybe some DtoA conversion, AtoD conversion, maybe
plans for homemade cards, interfacing with another microprocessor, anything
interesting in general.

Your best bet is to look in really OLD computer hobbyist magazines (pre-"A+"). Of course the technical reference manual for your Apple would be valuable insofar as determining what all the signals are, and what the peripheral slot addressing conventions are. I don't know if it's still available (probably not, now that Apple is "corporate"), but Apple used to sell a "Hobby/Prototyping Board" (Product Code A2B0001X) that was useful for wiring your own peripheral interfaces. The documentation accompanying the board explains the slot signals and I/O programming conventions, although there are some newer additional conventions (found in various Apple Technical Notes) that should also be followed for maximum utility. A (British, I think, maybe "BSR") company used to, and perhaps still does, market interfaces and remote sensors and controllers under the designation "X10". Real handy for automating your house..

I highly recommend this book: Understanding the Apple II by Jim Sather IBSN: 0-912985-01-1 Published by: Quality Software 21601 Marilla St Chatsworth, CA Lots of good hardware explaination and some projects. There is also a book by the same author called "Understanding the Apple //e".
