I had for my camera like a cable release (remote control). Although I have
the most convenient infrared remote control RM-CB1, but has her limits: The IR sensor is the front of the camera, you must have been so good visual contact. When does a distance then do nothing more.
Unfortunately, I did it with the Olympus Camedia 7070 Wide Zoom is not as easy as with some other camera: are the contact pads for the cable release hidden under the hinge of the battery compartment cover. In order to get ran because you have to remove the lid.
And an easy way to anchor there, something solid, like a connector that you plug, it does not exist.
here with the cover removed. produce The only way a contact to the pads seems to handle the battery B HLD20 there-to, but he is for what he can be quite expensive .
Why not just something like that from Fimo knead? :-)
said than done: (or so)
Using a pasta machine I have mixed Fimo in black and silver metallic to match the color on the camera body. 
see After several rounds the result of fairly perfect. With my hand I would have tortured me for quite a bit. for the tripod socket in the adapter and the adapter for the screw on the camera I bought two stand-bolts and the contact I bought so-called pogo pins.
Resilient contact elements that can be easily soldered. To the left: The battery compartment cover. order the adapter from clay also add nice to get straight before I even tinkered a water balance on the camera. To see in the blog entry: Why do I buy something not really ready?
Well ... And then what happened is strange: I've still managed to get a cheap battery grip.
So was my whole plan again thrown into confusion. :-D
new beginning:
Now I do not have to worry about me, as I have the contact elements attach to the camera, but in the end, I am so far from exhausted.
I want to give at least on the actual cable RM-CB1 by Olympus, which is just as overpriced and the battery grip B-HLD20 can be connected. This button can operate only autofocus and shutter release. With my solution, I have to control the zoom has also the potential and I can tell if the camera is turned on.
ribbon cable directly to the pogo pins in the B-HLD20 soldered. On the paper you can see the layout of contact pads. I've even numbered 1-5. The drawing above left, a look at the bottom of the Camera pose.
- GND:
- focus: internal pullup constantly.
- trigger: internal pullup constantly.
- Zooming: internal pullup only when the camera is on.
- Zoom out: internal pullup only when the camera is on.
Additionally, there are still in contact with me X: Simultaneous operation of focus and shutter release. By diodes, which are purely worked at a small board in the cable, I keep in mind that the focus and shoot each other.
end the other end of the ribbon cable in This 9-pin Sub-D connector with integrated thread for the mounting screws. pictures of cut out for Cut out the plug and have wegfräsen webs of interfering in the interior I once saved. First I had no nerve to the matter was so complicated enough. And second: If someone wants to rebuild. The position of the plug is really all you need to know. Only there is space for it. The rest follows by itself.
Why now of all this 9-pin plugs?
Very simple! I need to control only one of the Commodore / Atari compatible joysticks, which I have a pretty large collection. The arrangement of the connector is adapted to them.
* CLICK * First function test. lever back: zooms. Lever forward: zooms away. Both like the zoom lever on the camera.
lever to left: focus. Lever to right trigger. Fire button press: Focus and shutter are operated simultaneously. The latter I need only when I want, I focus first and later trigger. To get an idea, it is enough to press only the trigger, it is focused just before.
Juhu! Finally done! From the initial idea to the finished device are determined one year if not passed even more. Long Time, the disassembled battery grip rumgelegen just because I have not had the right idea, where the plug would fit.
