Re: Optical Image Stabilization magnet question
Hmmmm - A very interesting project.
You may have already thought of these ideas. I know less about anti-shake electronics than you do but, thinking out loud:
I would assume that the 'at rest', 'no shake' position of the elements must be the centre of the individual element travel distances.
what is the driving motor? is it a servo?
What is the signal that is being connected/shorted? It is probably be at CMOS level (8v) rather than TTL level (5v)...maybe?
What are those 2 4pin devices? are they marked, if so Google it and get the schematic or device details... are they part of the equation? Are they bridge rectifiers?
You have tried and analogue (potentiometer) control... is it more suited to digital control using something like a 555 timer (or similar) to generate variable pulse widths. You would need to experiment with frequency range.
Thinking about the physical movement of the elements during a camera shake, it needs to track the speed of the shake as well as the transit distance of the shake. The angle of the shake will be a ratio between the x & y axis.
Are any of the contacts that you connect a 'ground'? Or are they 'above/below' ground?
What is the make of the camera that it came from? It may be possible to get technical tedails from the manufacturers website (a long shot, but you never know!)
A few points to ponder on.... I wish you well with the project.
