After looking over the vast amount of Forum threads on modified servo positioning it seems that good ole resistance pots are very popular. I am using many modified servos with DIY gears with my project and would really like a good easy positioning fix. Has anyone tried using "hall effect" solutions? Cheap! Small!.....I am thinking of mounting/gluing 8 or more small magnets on one of my gears and having a hall device "signal" the EZ-B and with a running script to count, therefore knowing fairly well where the arm/elbow/shoulder is. Besides knowing where the linkage is I am thinking what with "slipages" it would be also good to have a "home" position with a second hall device, and with a script always bring the linkage back to a home spot! Does the SDK offer counting? Insights and comments are welcome!
Also this is a link of someone who has hacked a modified servo and embedded an IC AS5040 a 10bit encoder for feedback.
