Bo_Lorentzen Posted May 26, 2007 Share #1  Posted May 26, 2007 Advertisement (gone after registration) I frequently use my cameras with one or another automatic trigger solution. This seems like a fairly simple thing and should work also on my Digilux 3. so I picked up a matching minijack and tried to short the appropiate terminals.. no luck.. the camera behaved as it did not know it should be taking pictures.  So onto step two, I tested my cable release again, it still worked perfectly.. with that in mind I broke open the plastic handle and found the problem. Or at least I think I have found the problem.  In the handle of the cable release is what seems to be 3 resistors. arranged in serial, with a clever bridge function of the shutter resulting in a change of resistance of the cable when the shutter is depressed halfway and a further decrease in resistance when the shutter is depressed all the way.  I was surprised to see that the shutter only operates 2 leeds as I had thought there would be a common ground for the two states..  Clearly this would cause a lot of people to purchase a Leica cable release. (smile)  SOOO. about the question.. do anybody have any experience with hot wiring this setup, I need to plug this into a programmable timer which will close a contact for a determined period of time to take a picture repeatedly. My immediate solution seems to be plugging the timers cable in to the print board in place of the shutter button, and leave the resistors on the board.. but if I could make a plug with just one recistor and connect it straight to the camera that would naturally be preferred.  It seems that Leica's heritage of photography, science and travle ought to suggest their cameras would easily fit into a technical photography setup.. but no so for the Digilux-3.  Any suggestions...?  Sincerely Bo Lorentzen  My Leica scratch page - random thoughts , pictures and such.

Bo_Lorentzen Posted May 26, 2007 Author Share #2  Posted May 26, 2007 Update - there is 3 levels of resistance in the remote cable. normal = 40k focus = 4.7k (maybe this should be 5k) release = 2k  Im shopping for a handful of resistors this weekend.. with a little luck its simply a matter of adding a 2k inline for the relay.  Bo Link to post Share on other sites More sharing options...
ron110n Posted May 27, 2007 Share #3 Â Posted May 27, 2007 How about a detailed information of the complete process for your intended prototype. I don't have a remote to let you know. Also I don't intent to develop a prototype that is "similar in function" for something that I can get for less than $10 at eBay. Â Pls. post a macro image of the internal components of the D3 remote. Better yet draw a schematic of the remote and post it. The architecture should be simple. Â -Ron Link to post Share on other sites More sharing options...
Bo_Lorentzen Posted May 27, 2007 Author Share #4  Posted May 27, 2007 Ron,  It was pretty easy to put together, the hardest part being stuffing 3 resistors into a DIN connector plug. and it worked as expected. If it was not for the goal of being able to use motion control with the camera this experiment would not have been done. particularly since I had a perfectly good cable already. However I figure that there might be people who want to make a cable for a camera either the Leica or the Panosonic L1.  Remote Cable Release - do it your self - the Digilux 3  Bo  My Leica scratch page - random thoughts , pictures and such.

ron110n Posted May 30, 2007 Share #5 Â Posted May 30, 2007 Bo, Â I was looking at your drawing on the Din Connector. There are three terminals at the BNC Plug. What does the third terminal do. How about the ground? Â I thought you wanted automation on the release cable. Tell me if you want to hook it up on a Programmable Logic Controller (PLC). I can help you with that. You can do anything on a PLC. Â -Ron Link to post Share on other sites More sharing options...
Bo_Lorentzen Posted May 30, 2007 Author Share #6  Posted May 30, 2007 Hello Ron,  Actually to me the connector is not terribly important, just that the devise I am using it with here happens to have a DIN plug (Deuches Industrie Norm - or something like that - not my favorite connector) I already have the device and the 2 resistors did the trick and its clicking away like a happy camper as we speak.
