Picture of servo-activated camera


I am just curious how you have setup your camera with servo triggering.

My camera mount is made form a plastic switch box and is suspended under my Slow Stick on a wooden frame made from a paint stick. The cameras shutter button is pressed down by the arm of a HS-55 servo mounted to the top of the box. There is a hole cut in the top of the box to expose the button. The servo arm was slowly sanded to the right shape using a dremel with a sanding drum. Itís somewhat trial and error to get the servo arm just the right shape. You canít tell it in the picture but I glued a piece of 1/32Ē ply to the back of the servo arm to make it thicker. A thicker servo arm gives me better contact with the shutter button and ensures that it wonít miss its intended target. The cameras servo is operated my aileron channel since the Slow Stick is a stick and rudder only plane. If you wonder what the sticker is on the back of the camera mount I used my scanner to get a picture of the back of the camera and glued the picture to the back of the mount so I would know where to cut the holes for access to the buttons and LCD plus it has the added advantage of serving as a label for the buttons.

Hope this helps

Great idea!
It's easier than eyeballing and cutting..
Keeping those buttons on the back free from inflight pressures helps the camera actually work!

Is the camera itself cut/drilled/glued or otherwise damaged in the process of being mounted to the frame? I would hate to see that. Tripod mount is the only "natural" anchor point but I wonder if it provides enough support.

Easily removable. No alteration to the camera.

I use a nylon 1/4-20 screw in the tripod mount.

in worst case, you can hot glue a servo on. it does not damage the camera that way. I also use 1/4-20 nylon screw and include them in my kits. works well.

I built a plane specifically for 'lookdown' AP for a chap who's an archeologist - we couldn't work out why the pictures didn't seem to be working as well as we thought (we'd modified another plane to have a crude 'lookdown' mount before and it worked fine).

You've probably already guessed - the foam mount was pressing against the 'T' zoom button as the plane moved around and so the photos were quickly all maximum zoom (almost utterly useless for AP when you're looking straight down )

If you dont want to use the tripod thread find a little plastic box that fits.....a mount can be quickly and cunningly crafted with a knife and hot glue.
