So, you’re taking high resolution photos with your ancient medium format film camera — but you can’t be at the camera. Well, if you’re [curlyfry562] you build your own remote controlled mechanical shutter release!
Due to the age of the film camera, there really aren’t many (or… any?) off the shelf solutions to this problem. Especially not with the list of project goals [curlyfry562] came up with:
- It must be triggered by a remote TTL signal
- The wireless range must be at least 100ft
- It has to be reliable — medium format film is expensive!
- It needs to be easily mountable and removable
With his goals clearly set, he began work. He’s using 2.4GHz xBee modems which have a DIO pin — if you link up two for DIO line passing, then they act as clones of each other — change the state of one, and the other one follows. Using this he’s wired up the output to a microcontroller, which than powers a servo to depress the mechanical shutter release. It’s actually quite brilliantly simple.
If you don’t need quite as much range — check out this remote shutter release made from a wireless doorbell!
