Looking for some electronics guru who can help with my car project. Personally, my skill level/experience is below novice.
I have an ISIS system controlling the car electronics, including two of their optional components that allow me to control items via an ISIS supplied RF transmitter as well as an android smartphone.
Linear actuators open/close the doors and are controller by an Autoloc motor controller. You can program the run time for an actuator and when the motor controller sees a ground signal, it runs the actuator for the programmed time and then stops. Next time the motor controller sees ground, it reverses the polarity and runs the actuator in the reverse direction for the same time. If at any time during the up/down travel, it sees a ground signal, it stops the actuator. When it sees ground again, it reverses the polarity and the actuator runs the same distance in the opposite direction.
The motor controllers allow for a certain amount of adjustability for "sensitivity". Even on the controllers highest setting, it is sometimes not enough to operate the doors. There is no binding, the actuators have well over the weight rating needed and in fact work 100% of the time if I run power directly to the actuator motor. When the doors are acting up/stalling on the open cycle, very slight one finger pressure assisting allows it to run the full travel without stopping.
I have searched for other motor controllers that might allow more adjustability of the force, but have not found anything with the features I need. So I am left with trying to improve the ones I have or finding another product to try out.
Here is a link to see the actuators working: https://www.youtube.com/watch?v=eHSa6tjS6PI
Also, I attached a picture of the different parts/how they work together.
Any suggestions are most appreciated!
