Screw versus Belt: For time-lapse photography both designs work well. All the other cables, to the step motor, to the limit switch, the shutter cable to the camera and the Synchro cable from the camera are all moving with the controller. I have only one cable between the power bank and the controller. I chose that option - instead of the controller at one end of the rail - to avoid multiple cables running along the rail. If you do not want spanning keep the screw parallel to the rail. When the slider moves along the rail it creates a rotation of the ball head. If you move the screw away from the rail on one side you get an angle between the screw and the rail. A little arm connects the head to the screw. Spanning: A tripod’s ball head (as per the picture attached) is mounted on the slider. The rail has four legs but can also be mounted on tripods with standard screws. I bought the extrusion bar and accessories from RS.com (see the picture rs items.jpg attached). It is made of a heavy load linear bearing slider bolted to a slotted Aluminium extrusion bar. This value is entered as a percentage of the rail’s length in the variable: float ratio (i.e. You can decide what distance the ramping will last at the beginning and end of the rail. Quad Ramping allows a smooth easing in and out.this value is 400 for the rail driven with a screw shown in this instructable) When pressing the push button less than a second it moves the slider by a certain distance which can be set in the variable: int inchMoveval (i.e.this value is 500 for the rail driven with a screw shown in this instructable) Enter the maximum move allowed in the variable: const int maxLength (i.e.

So you may decide not to use the full length of you rail. For 100 pictures the value would be 10 mm. If you take 400 picture and your rail is 1 meter each slider movement will be 1000:400= 2.5 mm. The program divides the length of the rail by this number.

In LRTimelapse Pro-Timer you have to enter how many pictures you want to take.

this value is 63000 for the rail driven with a screw shown in this instructable)

Enter the number of steps that correspond to the middle of the rail in the variable: long midPos (i.e. To look at the frame composition at the start, middle and end of the rail when using the spanning effect, I used the long push option with the push button.this value is 126000 for the rail driven with a screw shown in this instructable) Enter the value in the variable: long endPos (i.e. Calculate the quantity of steps that correspond to the length of the rail between the limit switches.To adapt the controller to different rails some variables can be adjusted in the program: As a result the quantity of steps to cross the length of the rail changes from one rail to another. In addition the number of steps per rotation of the stepper motor and the length of the rail may differ. The pitch of the screw may vary or if using a belt the pitch of the belt and the number of teeth on the pulleys may also vary.

Material: Two cables are required from the motion controller to the camera (camera model specific) 1) a Camera Shutter Release Cable with a 2.5 mm Jack and 2) a Hot Shoe Adapter with a Plug to Male Flash PC Sync Cable Cord with a 3.5 mm jack.

This means that the slider will only move when the shutter is closed so will work regardless of exposure length. The camera’s flash is set to Rear-curtain Synchro, so the signal is sent back to the motion controller when the camera’s curtain closes. The signal to start the sequence comes from the camera’s flash hot shoe. After a picture is taken the Camera sends a signal back to the motion controller to move the rail’s slider on a Move/Shoot/Move sequence. The intervalometer sends a signal to the camera to fire the shutter. It means that I am using the LRTimelapse Pro-Timer Intervalometer to setup the number of shots and the interval between the shots. Operating principle: The Time Lapse Rail works on Slave mode.

I just added some code to control the stepper motor. (For more information see lrtimelapse-pro-timer-free) Gunther, thank you for this fantastic tool that you have made available to the time lapse community. This is a high quality Open Source Intervalometer for time lapse, macro and astro photographers that you can build yourself. For time lapse photography I use a Intervalometer called LRTimelapse Pro-Timer designed by Gunther Wegner.
