Remote Shutter Release
Just got an Olympus SP-800UZ.
Anyone know if there's any way to do a remote shutter control with this camera? (It's owl mating season up on the hillside and I'd like to get some photos without spooking the owls.) ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

One is common, one is half-press, and one is shutter. I don't remember which is which but it's pretty easy to figure it out.

I used a nice one, with 3 buttons (and 2 spare ones inside the remote ) transmittor. 3 relays on the receiver, to hook up to the camera.

I've done well with tying an npn from common to the shutter and ignoring the other (focus). Might have had to diode-tie the focus to the collector on one of the cameras. -- Jim |

Yep. Now entertaining electro-mechanical ;-)
...Jim Thompson I once used an R/C servo rigged up with a somewhat flexible flat nylon tab affixed to the end of the servo arm. The servo was mounted on a bracket from the camera stand in manner so as to have the flexible tab be able to push down in the camera shutter button when the servo was activated. Worked rather well within the operating range of the R/C controller unit. -- - mkaras |

[...] Will you be able to use the servo on the two position "shutter release"? And will there be a noise problem for nature photography (especially owls)? David, Good questions (the questions are always the fun part grin!). An R/C (radio control) servo is a "proportional movement" kind of thing: depending on the pulses it receives, it rotates CW or CCW some amount (up to a limit). It is capable, given the proper electronic and mechanical attachments, of letting you use (e.g.) a joystick to press a shutter partway or full down. What it does not provide is any feedback, so you need to measure (and mark) how far you would need to push the joystick in order to execute a "half-push" or "full-push". On your second question, I understand your problem. Deer and hawks are remarkably sensitive to the sounds my Panasonic FZ-50 makes when focussing and snapping; I can disable the latter, but only if I don't forget. grin! Most of the R/C servos I'm aware of are based on tiny DC motors, and have a slight "whine" to them as they operate. From what I've heard of owls, I'd expect that one would be able to hear a servo operating; whether this would affect them you'd have to read up on or test out. Frank McKenney -- War is repugnant to the people of the United States; yet it is war that has made their nation and it is through their power to wage war that they dominate the world. Americans are proficient in war in the same way that they are proficient at work. It is a task, sometimes a duty. Americans have worked at war since the seven- teenth century, to protect themselves from the Indians, to win their independence from George III, to make themselves one country, to extinguish autocracy and dictatorship in the world outside. It is not their favored form of work. Left to themselves, Americans build, cultivate, bridge, dam, canalise, invent, teach, manufacture, think, write, lock themselves in struggle with eternal challenges that man has chosen to confront, and with an intensity not known elsewhere on the globe. Bidden to make war their work, Americans shoulder the burden with intimidating purpose, There is, I have said, an American mystery, the nature of which I only begin to perceive. If I were obliged to define it, I would say that it is the ethos -- masculine, pervading, unrelenting -- of work as an end in itself. War is a form of work, and America makes war, however reluctantly, however unwillingly, in a particularly workmanlike way. I do not love war; but I love America. -- John Keegan / Fields of Battle -- Frank McKenney, McKenney Associates Richmond, Virginia / (804) 320-4887 Munged E-mail: frank uscore mckenney ayut mined spring dawt cahm (y'all) |

Most of the R/C servos I'm aware of are based on tiny DC motors, and have a slight "whine" to them as they operate. From what I've heard of owls, I'd expect that one would be able to hear a servo operating; whether this would affect them you'd have to read up on or test out. Frank McKenney -- War is repugnant to the people of the United States; yet it is war that has made their nation and it is through their power to wage war that they dominate the world. Americans are proficient in war in the same way that they are proficient at work. It is a task, sometimes a duty. Americans have worked at war since the seven- teenth century, to protect themselves from the Indians, to win their independence from George III, to make themselves one country, to extinguish autocracy and dictatorship in the world outside. It is not their favored form of work. Left to themselves, Americans build, cultivate, bridge, dam, canalise, invent, teach, manufacture, think, write, lock themselves in struggle with eternal challenges that man has chosen to confront, and with an intensity not known elsewhere on the globe. Bidden to make war their work, Americans shoulder the burden with intimidating purpose, There is, I have said, an American mystery, the nature of which I only begin to perceive. If I were obliged to define it, I would say that it is the ethos -- masculine, pervading, unrelenting -- of work as an end in itself. War is a form of work, and America makes war, however reluctantly, however unwillingly, in a particularly workmanlike way. I do not love war; but I love America. -- John Keegan / Fields of Battle ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Since New Yorkers think it appropriate to boycott Arizona over stopping illegal immigration and drug trafficking, I suggest that everyone else support building the Muslim Monument at Ground Zero |
