If you are looking into a well built Time lapse motion controller, you may have noticed how expensive these things are. An eMotimo TB3 for example (review | buy) will set you back about a grand and a Syrp Genie is not far behind (unboxing | buy). And none will provide full 3 axis motion control. So of course a possible solution would be to build a time lapse motion controller yourself. It is not an easy task, and gladly, Doug Urquhart over at Instructables is giving a pretty comprehensive tutorial.
