Hey all I am wondering what would be the best items to purchase for me to be able to turn this know (continuous) below:
I'm just needing to know what kind of servo torque I would need in order to turn that without issues of it getting stuck mid-ways.
i spoke to the original creator of that web site project that i linked to and this is what they had to say about the parts that were used:
Something like this:
As I mentioned above, I would need the stepper motor to have a continuous rotation in order for it to work with either of these dry food dispensers above.
There is a decent tutorial HERE but really doesn't give much information about how they went about building it and the mentioned Yocto-LatchedRelay seems over priced for something that can be done with just a stepper motor and some logic behind it.
I plan on using a ATMEGA32u4 with this project. I will have a total of 6 of these to control.
The handle/shaft is 2 1/2" long.
The paddle is 3" long
The base (measured from the inside) is 5 7/4"
So any suggestions on what would be best for this type of project would be great and I look forward in hearing them!

Are there any servos that have a hole in the middle so that i can slide it over the turning rod and screw down to tighten on it in order to spin it as if you were spinning it yourself with the handle?We used a small geared Maxon motor (great but expensive hi-tech stuff).
motor
RE-max 13 Ø13 mm, Precious Metal Brushes CLL, 1.2 Watt, with cables
Part-No.: 203888
gear
Planetary Gearhead GP 13 A Ø13 mm, 0.02 - 0.35 Nm, Metal version
Part-No.: 110316
Torque was on the low side: it was enough for regular cornflakes but clearly insufficient for muesli
The problem is not only about finding a motor with enough torque, it's also about finding a motor small enough to fit in the dispenser.
Here are the files. The pulleys were 3D printed,
but the bracket was laser cut in 3mm acrylic glass.
