Yep. I have a 10D & a 1Dmk2, both of which use the weird 3 pin
connector. I wish I could just use a stereo jack & wire up my own release.

No good for me, I'm afraid. If I could get hold of the 1D connectors,
I'd jigger up something similar for myself.

If you need a circuit for your camera, I'd be happy to jigger up a
design for you.

Get hold of a cheap wire remote for your 1D/10D (with N3 connector). Cut
the wire in the middle. Connect a female 2.5 stereo jack to the part
with the N3 plug, and a male 2.5 stereo jack to the part coming from the
switch (or ask a friend with a soldering iron, a multimeter, and some
common sense). Now you have: one cheap wire remote for your 1D/10D plus
one 2.5-jack-to-N3 adapter so that you can connect other stuff (or
insert a 20 yards extension between the two jacks).

Your latest little cut'n'paste message has become spam. You obviously
want another nastygram from your NSP. ;^)

2.5mm plugs are a bit fragile for my taste. If I do that, I'll go with a
metal 6.5mm plug+socket instead.

I've got all that. ;^)

They are not fragile on wire (the wire takes the bend). Using a 6.35
jack means that you can't use all the equipment made for Pentax and
entry-level Canon

Good. You can replace common sense with wiring diagrams, easy to find on
the net.

If I need to do that, I'll use a 3.5mm to 6.5mm adapter. I have a couple
of them in my junk box.

It's easy enough to trace with a multimeter.
