Grinder

1. A grinder, comprising:

a body comprising:

a first end;

a second end defining an opening; and

an interior surface defining an inner chamber extending from the opening at least partially towards the first end;

a chain positioned within the inner chamber, the chain comprising a plurality of balls and a plurality of links connecting the plurality of balls, wherein the chain has a length between 25 mm to 125 mm;

a motor coupled to the chain via an axle, the motor configured to cause rotational or reciprocal motion of the chain within the inner chamber;

an actuator configured to activate the motor, and

a cap moveably coupled to the first end of the body, wherein the cap is moveable relative to the first end of the body,

wherein the actuator is positioned such that depressing the cap towards the first end of the body actuates the actuator.

2. The grinder of claim 1 further comprising a power source configured to provide electrical power to the motor.

3. The grinder of claim 1 , wherein the chain is formed of one or more metals.

4. The grinder of claim 1 , wherein the balls are hollow.

5. The grinder of claim 1 , wherein the balls have a diameter between 0.5 mm to 5 mm.

6. The grinder of claim 1 , wherein adjacent balls of the plurality of balls are separated by a distance between 0.5 mm to 10 mm.

7. The grinder of claim 1 , further comprising an orientation sensor configured to detect an orientation of the grinder.

8. The grinder of claim 7 , wherein the grinder is configured to deactivate the motor if the orientation detector determines that a bottom edge of the grinder is not positioned at a predefined orientation.

9. The grinder of claim 1 , wherein the grinder comprises a single chain positioned within the inner chamber.

10. The grinder of claim 9 , wherein a middle section of the chain is secured to the axle.

11. The grinder of claim 1 , wherein the chain has a length between 10 mm and 60 mm.

12. The grinder of claim 11 , wherein the chain has a length between 20 mm and 50 mm.

13. The grinder of claim 1 , wherein the chain includes between two balls and twenty balls.

14. The grinder of claim 13 , wherein the chain includes between five balls and fifteen balls.

15. The grinder of claim 13 , wherein the chain includes between eight balls and twelve balls.

16. The grinder of claim 13 , wherein the chain includes between two balls and five balls.

17. The grinder of claim 1 , wherein the second end defining an opening is placed over a material to be ground, cut, chopped, pulverized, or broken apart.

18. A method for grinding a material, comprising:

positioning the grinder of claim 1 above a material;

lowering the second end defining an opening over the material so that the chain contacts the material; and

depressing the cap towards the first end of the body to actuate the actuator.
