This time I have upgraded to metal geared servos however they are still locked to +/- 90 degees and so they need modifying for continuous rotation.

Here I am using 2.2k ohm 0.1% tolerance smt resistors to replace the potentiometer and trick the servo into thinking it’s locked in one postion.

Last time I used some random through hole resistors I had lying around and when it came to trimming the servos there was a lot of drift, far more than I could correct for, so this shall be a big improvement.

Tiny!
