Sound trigger

[rokkstar]

Hi guys,

I've don a search on this and its not there or I've missed it.

Does anyone have any experience wuith creating a sound trigger for the D70? Is it possible? More to the point , is it affordable?

Cheers
Matt

Hmm... me thinks you'd have to make your own device with this and it would have to be done on the D70s with the cable trigger... the D70 is only capable of an IR trigger.

One of Nikon's Coolpix cameras in the 4mp range has this ability, I know that.

Why do you want it?

Damm.

It was for a project i was thinking of doing, whereby a sound would trigger the release.

I have posted this thread a couple of times. The Time Machine can be used with a sound trigger.

I built myself a sound trigger many years ago, also a breaking light beam trigger and a pressure pad trigger. I could use them all with the FE2s, but havent yet worked out how I can use them on the D70 easily. I guess I could buy a solenoid and use the trigger to activate it, the solenoid would have to be arranged to press the IR remote button, which would have to be pointing at the right part of the D70... all a bit much hassle really.
Of course, it would be much simpler if I could hack into the IR remote and use my triggers to close the contacts that the button operates... a project for the future.

cheers, Gordon

Matt, maybe a way to do it is find out if there is a pc sound trigger device, then tie that to Nikon Capture

The time machine looks like a good bet. How would the output of that trigger the camera though? I've read through the literature and it doesnt explain how it actually trips the shutter.

Reading more into this it seems like its a mammoth task.

A different approach might be use a sound trigger to trip a flash unit.

In a darkened room, your shutter could be held open, the flkash tripped, and then the shutter closed.

Rokkstar it triggers it via the IR shutter release. There is a module/addon you buy for the Time Machine that provides IR output.

I was going to look into writing an IR release for my Atmel AVR controller. Then I was going to add on a motion sensor and a sound trigger.

Sigh.....suppose I'll have to find time to do it at one stage. Along with the rest of the things I want to do. Wish a day comprised of 32hours, still only requiring 8hours of sleep. Would make it so much easier to do things

Just remember Kipper that the life expectancy is 81 years in Australia, which means that we spend 27 years in bed - 27 years without taking one photograph

Thats another point. I was thinking about that too. I would still need a trigger to fire the flash on an event though. Can you rig up a sound trigger for the SB 800?

Matt, here is an article on High speed photography with sound triggers, including instructions on how to make the bits. Is that any help to you?

Just came across the same article, and its very useful.
Thanks Glen.

Thank you everyone else too.

Matt, the other way if you have an idea when the event will roughly be is just organise capture to take a shot every second. Of course that is not suitable if you are trying to get a bullet going through an apple.

Sorry I can't help you with the trigger Matt, but it's nice to see you're already thinking about the decisive moment.
