These vibration motors are very small, I was impressed with how much vibration they could put out for their size. The rotor is exposed, which isn't ideal, but they are very inexpensive and I think that is a fair trade off. I didn't really have a specific project in mind before ordering these, but after messing around with them for a little bit I have thought of about a dozen different projects you could build with these. Good components to have around

I got these to add haptic tactile feedback to some of my Arduino devices. These motors create vibration when the eccentric weight on the motor shaft is spun. Unlike many other haptic motors, this spinning weight is not enclosed, so care must be taken to ensure that project wires and other things can't obstruct the spinning weight.The device measures 4.83mm square including the rubber sheath. Length of the motor case is 8.01mm and total length is 11.26mm. The motor body measures 4.02mm in diameter. Leads are 45m and the tips are stripped 1.5mm and tinned. The square rubber sheath can be glued to your project with cyanoacrylate glue, though hot melt glue and a wire loop anchor around the metal motor case will probably be more robust.I tested this at 2.7VDC and it worked great. Although you can write your own Arduino code to control this motor, it will work better when combined with a Texas Instruments DRV2605 haptic motor controller chip. This chip has 123 different pre-programmed vibration effects that you can access via software, saving you a lot of trial-and-error and programming time. This chip is available on breakout boards from Adafruit and SparkFun along with programming instructions.

These motors work, but the wires are so tiny and breakable that they are very difficult to connect to anything, and its hard to get a solid connection when you do. They are definitely meant to be soldered in place by someone who knows what they are doing. There is also not enough uncoated wire available at the ends to easily connect. They are not so great for making brush robots or doodle robots with kids, they are too small and fiddly for that, and they don't have enough power to move much either.

These are terrific. I was a little concerned about the lack of an enclosure, but that hasn't been a problem in practice. These work great with the SparkFun controller boards and you can also roll your own with the same chip from TI. Really a great find.

This product has some incredible write ups already, so I will just share my simple experience. These work according to the listed specifications. They can vibrate anything up to about the weight of a cell phone without issue. I am using mine to add some fun activities on a model train layout and while it takes a little tinkering to get things the way I want them, they are certainly working out.

I needed vibrators for an Arduino development project. Dimensionally and spec wise these looked good on paper; with only 3V needed it was workable although it requires a starting current of 75mA; which exceeds the output current for Arduino BUT a simple transistor or logic chip solves that. These put out more than enough vibration for it's size! I did not see any self adhesive solution as mentioned; so, hot glue it is! Honestly, I would use hot glue regardless... but just fyi - there is not any self adhesive as mentioned in the description. Also, the wires are tiny; so, take care when stripping and soldering! You've only got so many attempts before it's a wrap! lol.Overall, this is a great value for the bundle!

I got these for a miniature vibrating robot project. These are the smallest motors I have ever seen once you remove the rubber cover. Very good for a small project.

The motors work fine and I ran one full one for a minute without any heating. The problem for me was that I wanted to vibrate a larger (heavier) object than a cell phone and it came up short ... but that is a design issue on my side, not a problem with this product. I think these work well.
