Any electrical engineers here? Vibrating motor + time control

[Departed]

Hi guys,

Are any electrical engineers here who could help me get a basic understanding if the following would be simple or difficult to engineer?

I want to insert a small vibrating motor (like this one for example Coin Motor Vibration Dc Motor Cellphone Motor 0820 - Buy Coreless Dc Motor,Coin Type Motor Vibration 0820,Health Protection Equipment Motor Product on Alibaba.com) into a piece of plastic. Then I want the user to be able to switch between different modes when/how often the vibration should occur (every 2 hours, every 4, every 8). Ideally with just one button, no display, maybe 3-4 small led lights to indicate which mode is in use.

What would I need besides the vibrating motor? Some kind of micro-controller, a battery and some LED and a button? How would one go about this with no electrical engineering knowledge at all? Who could I hire to help me design a prototype?

Appreciate hearing your thoughts!

I'm not an electrical engineer, but a bit of a tinkerer, this should be very easy to make from an electrical engineering point of view. I think if you go to an smaller manufacturer they may be willing to do the design. Or recommend you someone to do it for you.

You can also look for en electrical engineer or embedded systems engineer to spec it and write the limited code (if any). And an industrial designer to get the PCB and battery in a housing and do the CAD work.
