This is really a motorized finger that pushes the button of your camera for you. The time between shots is determined by the speed of the motor. By hooking up different battery combinations you can change the voltage to the motor and change the speed of the motor. You can create some great looking timelapse movies just like the pros at a very low cost.

This is most of what you need for the cameras I used. Adjustments will be needed for
larger or smaller cameras. I have two cameras that will work but the finger that
pushes the camera button will have to be adjusted.
Miter saw is nice but all of this can be cut with the correct hand saws
Hole saws 1-1/8 and 7/8 inch
Drill press makes it easier to cut spacers but it can be done with a hand drill
(Center pilot drill is removed to cut little wheels out)
You can also use a stack of washers for spacers.
