Remote Mechanical Shutter Release

I see you used high quality rubber bands there : ). Are you using a joystick type controller to flip the servo down?

The transmitter has a trigger. Pull trigger to take picture.

Did you watch the tutorial?

I had a look around there but did not find what you were referring to, Randy.

Randy, the pololu controller makes sense, but not all that clear how much torque (in a servo) is needed for the trigger. Not really keen to get something that's way over or underpowered. How many kilo's is your servo ?...and does it behave as you wish ?

I am using it on a Packard, and it's servo speed I need. I'm still fooling with it. I use battery pack and momentary switch. Short push, shutter is wide open, longer push, it completes the cycle. 3-1/2" shutter running consistent 1/2 second, with adjustable flash sync, which works fine in studio.

I never played with this stuff before. It all is tiny, lightweight and easily fits inside a LF camera or out.

Here are the Pololu part #'s I used.
1350 servo controller
2804 relay for flash
2140 servo for shutter

Of course I just bought this on eBay which does it all. NOS, steel blades. But it needs a manual hold the shutter open lever added for focus.

For a special application LF lens I just used a R/C servo (in my case stripped to the micro-motor and gearbox) to trigger the #1 Press-shutter.
No fancy anything was needed, other than a way to mount it, but it was limited to direct switch/battery circuit triggering, or potential use of a standard R/C remote.
