Step 1: Materials
3 inch section 3/4" PVC piping
One 3/4" PVC endcap
One 1" PVC endcap
One 3/4" PVC "T" with threaded center, smooth ends
Flat toggle STSP switch
AA battery and holder
Small DC motor
Wire Coat Hanger
Tilt switch (optional)
Heat shrink tubing (optional)
Step 2: PVC Stand
Attach a zip-tie about 1" below where the wire enters into the PVC and secure. Just below the zip-tie, bend the wire at an angle to give the PVC a nice standing position.
Step 3: Motorize It, Vibrobotize It
I threaded the wiring through the PVC "T" and soldered it up. The threaded portion of the "T" is very useful as it allows the motor to just screw in.
I added a tilt switch because my kids were always playing with the Vibrobot and then just leaving it on the floor on its side still running.
Step 4: End Cap Switch
In the end cap, a hole was drilled which allowed the toggle switch to be screwed in without threading first.
