How to make a portable variable speed linear slider motor for about $55 AUD

Learn how to make a portable variable speed linear dolly / slider motor for shooting timelapse videos that can be used on any slider rig for about $55 AUD.For about $85 AUD you can have a deluxe version with two motors, one for timelapse and another for regular speed shots, USB power and a dedicated 12v battery and charger. Here's a little day trip I did to test the unit out vimeo.com/88152086. It rained the entire day, so it wasn't ideal, but you can see that it works!

The slider used is an 80cm Konova K2. you'll need an intervalometer - I use Magic Lantern on my 6D, a hack which allows you to do intervalometer shots in-camera, but you can buy a unit off eBay for c. $30. Be sure to get one that can take an infinite number of photographs, many timeout at 99 (4 seconds of footage).

Shoutout to Style43 (vimeo.com/12120373) and Joakim Fjeldli (vimeo.com/22337471) for the inspiration.

// Shooting Advice
1. Have fun!
2. Put a bit of tension on your sliders bearings and you'll get silky smooth motion, and use fishing line (or any string for that matter) that doesn't have any elasticity or give.
