Problem with my Twinned Nikon Lite-Touch

[P3D Charles A Miller <oravaxcm@xxxxxxxxxxxxx>]

Hello All, 
        I would have sent this to Ed Comer individually, but I can't seem
to send him email directly (it always comes back to me. If I hit reply,
his email address isn't recognized). Anyway, I put two Nikon Lite-Touch
cameras together (at least I had something to do during this storm here in
Boston). Anyway, after some troubles (I had more trouble putting the base
together and drilling the holes correctly than soldering the tiny wires
onto the circuit boards...I'm NOT very  good with wood working). Anyway, I
was testing to see whether the cameras are linked. They work! When I put
them on the mount, I can make them fire together. The mount is still a
little rough (the cameras don't stay in very snuggly, but that was
probably because I didn't put the balsa edges on it to form the pocket.
Also, I need to add spacers to shorten the T-bolts I am using in the
tripod mount holes). After I fire the cameras, they won't shut-off, change
modes, or file again unless I ease up on the pressure holding at least one
of them against the contacts then press that camera firmly back down to
make contact again. At this point, the little flash/autofocus light on the
backs will flash once in sync, indicating that I can fire the camera(s)
again. I can change modes/turn off/fire either of the cameras as soon as I
release one of them from making contact. I can't figure out what is
causing this. It seems to me that if there was a cross or short anywhere,
the cameras would fire as soon as they made contact. It almost seems like
once they fire, they are stuck in some kind of feedback loop or something
(just making this up...I have no idea). If Ed or someone who has
experienced similar problems could get back to me, I'd be most grateful.
The only difference I can see between Ed's cameras and mine
(electronically) is that my circuit board has a big number 2 where his has
a big number 1 (as seen in figure 3 of the latest directions for building
the cameras). Is this the kind of problem that can be solved by
incorporating a diode into the circuit in the camera1 to camera2
direction? (its been years since I took electronics back in high school,
so I don't have half a clue!)

Thanks! 
(I look forward to taking pictures with these cameras even if I have to
put some sort of reset switch in between them!!)
