David,  here is what I have so far...
I like the Ricoh switch you linked though I am not looking to buy another switch. I would like to use the one I am currently trying to configure.  I would like to know how on the Ricoh they got a 1.5 AAA to operate at 5v pulsing.  I would then like to know how to solder the battery into the switch and how to wire the 3.5mm female jack onto the other end of a 4 pin USB mini B cable. Just the wiring schematics, I will work out the housing aspect of the battery to the switch.
I have access to a button battery holder that holds 3 LR41's rated at 1.5v each, or a 3 AAA battery housing from a remote control car, or perhaps a 9v? I will be connecting that to a 3.5mm extension with an 2.5mm to 3.5mm adapter. The extension will hook into a USB mini B cable with a 3.5mm female end on the other end to plug in the 10' 3.5mm extension cable.
I am a stay at home dad with my 8 month old boy, which as you can imagine, makes it somewhat difficult to concentrate or focus for any length of time. So help with this matter would be VERY appreciated.
Thank you,

Scott

If this post gets help I would like to send back the karma somehow...

The USB signal is not displayed in Misc values on all cameras.
If it was, value 3 fifth digit should change from 0 to 4.

3V is not enough for A570, it needs to be at least 3.4V, maybe more.

Plug into the computer for testing to be sure of a big enough voltage.

I did plug into computer but not doing anything. Even used ZoomBrowser EX- nothing when clicking on "connect to camera".


Any ideas?

You have to use a script that is waiting for key "remote".

Here is Fingalo's  :-

@title Remote button
:loop
wait_click 1
is_key k "remote"
if k=1 then shoot
goto "loop"
end

Where on my SDHC card do I place the script? In the DISKBOOT file or the PS.FIR file?

The script has to go in the CHDK/SCRIPTS folder (that's where all scripts have to go).

Here is pin-out Untitled Document

Connect battery positive to ring (or tip) and connect USB cable red wire to tip (or ring).

That assumes the USB cable has standard colours for the wires.

Thank you David.  I hope this does the trick. The only thing missing in the pics of remote are a battery source. I take it that the battery would wire in line with the switch on the positive end.  I will find out in the next day or two.

Because a battery is not required for the intended application of that switch.

In my opinion, this is a slightly messy solution, you have a battery external to the switch.

The switch may look nice and 'proper' but it is just a switch.

Many alternative solutions have been published here that are inexpensive and self-contained.
