Hello everyone, we are in need of some help and maybe even hopefully some collaboration.
In a nut shell, we are a small film group that just started getting into Arduinos in the hopes that it would help make our life a bit easier and allow us to build ‘equipment’ that we cannot afford. With that being said, we have started an Arduino controlled camera slider project and could use any help that we can get.
Instead of building the slider from scratch, we decided to cannibalize an old HP Designjet plotter for the linear motion that originally drove the print head shuttle (see attached). We’ve purchased an Arduino Mega and a couple 4 channel relay modules. On order is a couple Nema 17 200 step/rev 12v motors along with an Adafruit Motor\Stepper shield and some other ancillary items. Mechanically, we are sound, however, when it comes to the software side of things…we are completely lost.
First off, we are seriously wondering if an Arduino can pull off what we are trying to achieve or if we should dial it way back. Obviously, we are wanting to control the linear motion in the X Axis in order to make the camera slide back and forth via a single axis joystick, but we are also wanting a “speed buffer” at the beginning and end of movement that way the start and stop is not as ‘violent’ (more kinesic and less robotic). We are also trying to get the same characteristics in lieu of a camera pan motion (Z axis rotation) with another stepper motor controlled by a different single axis joystick.
We’re also wondering if it is at all possible to ‘record’ a series of movements and be able to ‘play’ them back to get the same camera movement repeatedly (with both X axis linear movement and Z axis rotation).
If anyone can help shed some light on this or could help with the programming, it would be greatly appreciated. Our main goal of this project is to not only have an awesome camera slider, but we want to put the information out there so that other filmmakers can build the same style of slider without having to slam their head off of the walls for weeks on end.
