Ho, hum, another camera slider, right? Wrong — here’s a camera slider with a literal twist.
What sets [Schijvenaars]’ slider apart from the pack is that it’s not a slider, at least not in the usual sense. A slider is a mechanical contrivance that allows a camera to pan smoothly during a shot. Given that the object is to get a camera from point A to point B as smoothly as possible, and that sliders are often used for long exposures or time-lapse shots, the natural foundation for them is a ball-bearing linear slide, often powered by a stepper motor on a lead screw. [Schijvenaars] wanted his slider to be more compact and therefore more portable, so he designed and 3D-printed a 3-axis pantograph mechanism. The video below shows the slider panning the camera through a silky smooth 60 centimeters; a bonus of the arrangement is that it can transition from panning in one direction to the other without any jerking. Try that with a linear slider.
Granted, this slider is not powered, but given that the axes are synced with timing belts, it wouldn’t be difficult to add a motor. We’ve seen a lot of sliders before, from simple wooden units to complicated overhead cranes, but this one seems like a great design with a lot of possibilities.
