It’s a little like the CoreXY mechanism rotating the motors in the same direction and speed slides the carriage, while moving them in opposite directions pans the camera. Instead, the motors, which are located near the end of the slider rails, transmit power to the carriage via loops of 217timing belt. The design is a bit unconventional in that it not only dollies the camera left and right but also works in pan and tilt axes, and it does this without putting any motors on the carriage. We mention scope creep because that’s what blames for this slider’s protracted development time, as well as its final form. It’s how we end up with wonderful builds like this multi-axis differential camera slider. That may be, but sometimes the creep is the whole point. “Scope creep” is often derided as an obstacle between your idea and the delivery of a finished project. Here’s a more complicated one, and another one.Ĭontinue reading “Super Simple Camera Slider With A Neat Twist” → Posted in digital cameras hacks Tagged camera slider, dc motor, motion control, pan, Tilt, timing belt We’ve seen a few slider designs, since this is a common problem for content creators. Other than a 3D printer, there is nothing at all special needed to make yourself quite a useful little slider! A pair of microswitches are used to stop the motor at the end of its travel. We were just expecting a pile of STLs, so seeing the full source was a nice surprise, given how many open source projects like this (especially on Thingiverse) do often seem to neglect this.Įlectronics consist of a simple DC motor controller (although doesn’t mention a specific product, it should not be hard to source) which deals with the speed control, and a DPDT latching rocker switch handles the motor direction. The CAD modelling was done with Fusion 360, with all the models downloadable with source, in case someone needs to adapt the design further. Super simple, low tech and not an Arduino in sight. With a few tweaks, the slider can be vertically mounted, to give those up-and-over shots. The ends of this guide rod can be offset at either end, allowing the camera to rotate up to thirty degrees as the slide progresses from one end to the other. The added twist is that the camera mount is pivoted and slides on a third, central smooth rod. That’s a cost effective way to get your hands on a nice high-torque motor with an integral reduction gearbox. This design uses a geared DC motor, taken from a car windscreen wiper. was no different, and designed and built a very simple slide, but with a neat twist. Buying one can be an expensive outlay, so many people opt to build one. The answer is quite often some kind of mechanical slider which sends the camera along a predefined path. When you get into making videos of products or your own cool hacks, at some point you’re going to start wondering how those neat panning and rotating shots are achieved. With a little work, these could be used to actually control at least a couple of axes of a motion control rig, or maybe even to play Quake.Ĭontinue reading “Kino Wheels Gives You A Hand Learning Camera Operation” → Posted in Misc Hacks Tagged Arduino Mega 2560, bearing, din, encoder, handwheel, pan, simulator, Tilt While getting camera practice is the point of the project, that’s not to say Kino Wheels couldn’t be retasked. A little bit of the simulation is shown in the brief video below, along with some of the build details. The operator-in-training uses the wheels to keep the scene composed properly while following the action. Connected over USB, the wheels control the pan and tilt axes of a simulated camera in an animated scene. To use Kino Wheels, offers a free camera simulator for Windows. The handwheels are mounted orthogonal to each other in a suitable enclosure the Pelican-style case shown in the build instructions seems like a perfect choice, but it really could be just about anything. The handwheels are supported by sturdy pillow block bearings and attached to 600 pulse/rev rotary encoders, which are read by an Arduino Mega 2560. The business end of Kino Wheels is a pair of DIN 950 140mm spoked handwheels - because of course there’s a DIN standard for handwheels. Getting the hang of camera controls is the idea behind ’s Kino Wheels open-source handwheels. And getting to that point requires a lot of practice, especially since the handwheel controls for professional cameras can be a little tricky to master. Have you ever watched a movie or a video and really noticed the quality of the camera work? If you have, chances are the camera operator wasn’t very skilled, since the whole point of the job is to not be noticed.
