Hello. I started making one of those useless machines (leave me alone box?) but my box is pretty tiny. The inside usable area is 3" long x 2" wide x 2" tall, so i need a motor that will fit in that space along with a couple batteries, a small switch, and the arm. I've found several that would work as far as size goes, but am unsure on the amount of torque i will need. The toggle switch that the arm will need to push is Radio Shack part 275-636. The arm will be made of 1/4" wood, as will the door that it needs push open before hitting the switch. This is a to-scale representation using **broken link removed**:
Of course that does not show the inside switch, batteries, or anything else. The specs on that motor show 11.00 in*oz torque at 3 volts. Do you think that is enough to do the job? If not, how much torque would you guess is needed to do the job? I know that's probably hard to say considering i can't really tell you how hard it is to move the toggle, what kind of hinge i am using, or how heavy the arm is... but any advice you can offer would be appreciated!
Such a fun waste of time
