Vibrobot from old camera

Step 3 Build

Strip the ends of the wires to the motor. See what it will run on power wise. This one seemed to run ok off one of the two included AA batteries. Attach an offset weight to it. Here I use the battery compartment door, as it had a small springy part that snapped fairly tight to the cog on the motor. I then taped the motor itself to the top of the front of the camera case, as it kept the spinning (and wobbling and vibrating) battery compartment door off the ground. Tape the battery to the other side (or anywhere else it fits).
