Re: The Best Encoders for Drivetrain
For coupling, we've used 1/4" shaft couplers. On our air cannon (in which we made a mini-cim and TB-mini into a servo), we coupled the shaft on the mini to the stub on the back of the gearbox and a potentiometer. This provided plenty of support for the pot - we just had to keep it from rotating. We found that some 10GA steel wire fits those encoder mounting holes nicely. We bent about 8" of this wire into a sufficiently rigid structure to hold the pot in place.
