I’m looking to create a stand-alone micro rechargeable circuit including the following:
-A micro vibration motor (coin-type for packaging purposes )
-A speed controller including a tack switch for on/off and momentary tacks for increasing and decreasing speed. These need to work after being plastic coated.
-A rechargeable (USB?) lithium battery holder
This whole package would ideally be less than a 2" diameter round package to start and less than an inch thick.
This would be a pretty simple auxiliary device I’m just not exactly sure how to size such small parts including the controller and having a very small package that can also withstand being dropped.
I would appreciate any input!!
