This slider is based on the Igus Drylin slider.
I was inspired by another video here on Vimeo, vimeo.com/12120373.
But, I decided to take it a step further.
Sample video here: vimeo.com/38747342 A bit slow speed on the slide, but you get to see how it works.
Power: 12v lead acid battery
An on/off switch was added.
I used a 12v DC/DC adapter with voltage control to control the motors speed. This way, I am able to control the speed in incremental values.
Example: At max output (12v) the motor drags the camera across the slider rail in about 8 minutes.
At 6v it uses twice that, about 16 minutes.
The lowest setting on the adapter is 1.5v, which gives a ride that lasts over an hour.
Everything built into plastic casing.
I used the same motor as STYLE43, a 2rpm 12v DC motor.
Fishing line was also used to pull the car on the rail.
An intervalometer (timer remote) is used to control the exposure interval (and amount, if needed).
Music: Sheridan Tongue - Symphony of Light
Video: Canon EOS 7D / EF 24-70mm f/2.8 L
Timelapse: Canon EOS 5D / EF 17-40 f/4 L and GoPro HD Hero.
Sorry for glitchy video and sensor dust spots. Wont happen next time.
