Description: A vibration motor! This itty-bitty, shaftless vibratory motor is perfect for non-audible indicators. Use in any number of applications to indicate to the wearer when a status has changed. All moving parts are protected within the housing. With a 2-3.6V operating range, these units shake crazily at 3V. Once anchored to a PCB or within a pocket, the unit vibrates softly but noticeably. This high quality unit comes with a 3M adhesive backing and reinforced connection wires.

I was super excited to build a bristle-bot with my 3 ½ year old. It lasted only 3 minutes. One hit on the floor and the vibration motor came apart in pieces. Her first robot, dashed. Bummer.
Quite possibly my own poor judgement to let a 3 year old play with it, but it is supposed to vibrate. I thought it would be a little more sturdy…
Received the motor in a timely way, works great !. If you need one buy it from sparkfun !
I like this motor very much! I purchased a couple for toothbrush robots á la Bristlebots and they work very well for that. The flat profile, and the sticky side makes it even easier to use. My one disappointment was that I couldn’t seem to power one from a 3V CR2025, but it could have been that my stash of batteries is getting old…
I incorporated this vibration motor into a little pet project I’ve been working on and have got it to the point that it works good enough for me. I’m an experience programmer (mostly C/*nix) but am interested in the embedded world. I used this motor with an attiny85 (for timing) and a few other components to make a ‘mouse mover’ (doesn’t actually move the mouse) aka ‘executive override’. I work from home and company policy mandates the screen lock after ten minutes. This is darn inconvenient when just monitoring for email. This device will move the cursor about every four minutes, freeing me from constantly moving the mouse myself.
I power the device from a USB port. I burned out a couple of the motors before I realized the voltage was too high. I moved the motor to source side of the mosfet and the voltage drop across the mosfet was enough to protect the motor and still provide stable operation. Below is a video of the final product. It is messy looking but has been working reliably. The vibration motor translates to cursor movement by moving an image just below the mouse. The large buypass capacitor (+ to ground) wasn’t the best choice because the attiny85 keeps running on it for a while after the USB is unplugged.
The video is about a minute long.
Thanks SparkFun, I learned how to program the attiny85 with all of you online resources.
