super good !

Wouldn't the imbalance that causes the vibration wear out the bearing in the motor?

you dont have any current limiting resisters in there? i figured you would burn out the motor pumping 5v into it.

[HHarry]

I stress tested the motor for about 15 minutes at 5,35 volts on my bench power supply and it didn’t got hot. So I think the motor can handle it. But you are correct, normally you have to be careful not to burn out the motor.

I would have made the massager more complex: speed control, rechargeable batteries, indication lights… But the general idea of this project is that someone with neither woodworking nor electronic skills (first time solder and circuit build) could make something creative.

i am not huge into the home electrical thing so could you give a noob an idea about where to get those things you put on the motor as a counter weight? i dont mess with that much voltage since i got hit with 3 phase 440 when i worked at the railroad. anything over like 13 volts just makes me shake now.

Just go to your local hardware store and ask for a block connector or terminal strip. It will probably look like this:  http://www.transformer-parts.com.au/weiland_terminal_big.jpg

Pervert. ;-O) 5 stars and my vote.

[HHarry]

Thanks! (not for the pervert part)

Will super glue really hold that vibrating motor in place for long?

[HHarry]

Yes I think it will hold for a long time, a previous version is working several years now. The key element with super glue is pressure, the harder the pressure while gluing the better it will hold:http:// http://www.guinnessworldrecords.com/Search/Details/Heaviest-weight-lifted-with-glue/65830.htm

Awesome. I know superglue is strong, but I was unsure of how it would deal with vibrations.

Nice job. Wood work is flawless from the pictures. Great idea. I can tell you had fun making this.

[HHarry]
