ALCS 5-speed crystal controller

[Aapo Lettinen]

I did some drafting when thinking what kind of possibilities I would have to design a low cost easy-to-assemble solution for crystal controller which can be installed inside cameras by other designers. This is a derivative of my 4-speed and 6-speed Universal crystal controllers but the fps change button is left out so that one can use one's own strategically positioned switch for fps change, and the panel made as compact as possible assuming that the bldc control board is installed elsewhere. Current panel dimensions are approx 55mm X 25mm. The current circuit board is made affordable to assemble to lower the price, if making a more expensive board the circuit board could be made much smaller and thus the panel smaller too though the price would increase considerably.

These are NOT meant to individuals who only need one or two easy-to-install crystal motors as "out-of-the-box" solution. These are targeted for people who are designing their own line of camera accessories and want to integrate a readily available crystal controller module to ease the design process a lot and save a year or more of time and thousands of bucks on costs. The controller is integrated to the backside of the panel and one runs wires from it to a separately purchased factory made bldc board which runs the brushless motor drive. The controller uses 0-5V control line to adjust the motor speed. These are meant to be used with 14.4V batteries but 11V to 20V does work fine. I want to concentrate on making these controllers only but can help with arranging bldc boards and motor drives if needed, for example similar ones than my 4-speed motors use. 

Minimum order is 5 pieces of controllers at a time but preferably I would sell the controllers 10 at a time to get better pricing and can calculate good pricing for decent size batches. If wanting a ballpark of the pricing, these cost under 200usd a piece even if bought 5 at a time but one can negotiate a deal when knowing how many needed and when. 

Estimating the first ones could ship in September-October 2026 depending on if there is orders. I should be able to make these in 2027 too if there is demand but same minimum order amounts apply.
