Looking for shaker motor suggestions (for non-pinball application)
(1/2) > >>
Mysterioii:
Hey guys, hoping someone here can give me some suggestions. I'm planning out a Halloween display (if I have the free time to bring it to fruition) and one thing I'd like to do is hook up some shaker motors to rustle/shake some branches... Just doing some quick searches what I'm seeing on ebay are $260 Stern kits or weak little pager motors and "personal massager" motors.   ;D  I need something beefier than the little guys but $260 is way out of my price range.  Hoping for something more in the $20 ballpark. I know really any moderate-sized DC motor with an offset weight would be workable for what I want to do.  Not sure where to get offset weights by themselves, so I'm considering just finding a motor and trying to make my own offset weight. Sounds simple enough, but I want to make sure that it's durable enough that the weight doesn't go flying off on it's own.

Any thoughts? Anyone have any sources for used-but-workable shaker motors, or have any experience making your own?

Thanks!

Haha I guess that's a possibility but it's probably still overkill...  I could probably get any reasonably sized DC motor in the 12V range and put some sort of offset weight on there, I just want to make sure it's sturdy.  I could cast a weight out of lead (old solder probably) but I'd need to embed some sort of fastener to grip the shaft since I doubt the lead by itself would hold up...

Hit up harbor freight for a cheap reciprocating saw (don't forget the 20% coupon from the sunday paper  :lol ).
Attach a weight to the end, or stretch a rope between the branches and the saw.

Not a bad idea either... my recip saw is pretty noisy though and I'm hoping for something that will do it's job pretty quietly...  I'm thinking a DC motor with an offset weight might be relatively quiet but come to think of it I might be deluding myself...  The Electronic Goldmine carries several variations of DC motors, I might pick a few up and experiment.  (They're not exactly a digikey or mouser, but for random little surplus bits for pretty cheap they're not bad).
