For some time I've been processing on the technical details of a high quality gyrostabilized gimbal for Epic and Scarlet.
We all know that high quality gimbals are very expensive. I've learnt that they start from $150K - $250K, and one easily makes an assumption that the high cost is somehow forced on us by the nature. And yes, scientifically we know that there is no way to recognize gravity from other mechanical forces/accelerations acting on a moving object, so proper stabilization requires highly skillful engineering. The other side of the coin is, take a look at a $150K gimbal and compare it to a car which costs $150K --what is your conclusion on that?
Once I've put my mind on this I've become convinced that technically it is possible build a first class fully gyrostabilized gimbal for Epic/Scarlet with a reasonable cost. I have been developing high accuracy navigation systems etc. and have quite a lot of experience in developing challenging engineering products and thus feel not standing steadily 20cm above the ground level. Furthermore, I'm talking about using the gimbal when shooting from car, boat/ship, snow mobile, RC helicopters etc., but not about airplanes or helicopters as that's an regulated area.
If you've read this post up to this point and you are still interested in the subject, let me point one interesting detail making the challenge bit easier; Designing a gimbal to Epic or Scarlet is easier than designing a gimbal to Red One. For, with Epic one needs to stabilize only the brain and lens and consequently in both cases there is less mass to stabilize than that of Red One. (A word of warning; Still one should not expect the Epic brain will weigh almost nothing. Second, it is not yet clear how long cable one may attach between the brain and the rest of the camera.) Less mass imply smaller and cheaper motors, and the cost reduces much faster than linearly with respect to the mass.
Basically I'm just interested in getting a proper gimbal, but buying the existing products are not economically justified. Second, have neither indefinitely time to design a gimbal. For this reason I decided to make an attempt to find out how many other people are interested in such kind of gimbals and who could contribute something if such a system is developed. You know, this post is about probing whether a kind of Linux approach could work out. That is, eventually if everything worked out we posted on RedUserNet drawings, list of components, software etc. enabling anybody who knows how to use a screwdriver to construct a gimbal or some 3rd party takes over and finds the outcome as a business opportunity.
So, if you are still reading could you reply if you have an interest in a reasonable cost gimbal, and second, if you could tell whether you would be willing and able to contribute something on designing such a gimbal. If yes, to get an idea of feedback, could you rate yourself exploiting the following guidelines:
1) High experienced user: You are able to tell where the technical challenges lie in practice. Such as, you are able to tell which axis pan,tilt or roll is most critical one to stabilize.
2) Skillfull designer in engineering: You know say what is a PID-controller, what the moment of inertia is, or you know why modelling of the mechanics of the gimbal is important.
3) Electronics/electrical engineer: Your are able to distinct between embedded system, induction machine and stepper motor, and you know how motors are driven.
Have no idea whether this attempt will crash immediately or whether it will lead somewhere, but at least there's an attempt. Finally, if you hesitate to post in public, send me a pm. Those filled with pessimism, could you please let others to have a rational discussion. Thanks
