Electronics
So do you have some engineering talent?  Even if you don't you can create some
unique products that you can make available for resale.  This page will walk you
through some steps based on the fact that you are NOT the engineer in charge of
designing the product.  This will approach the fact that you are the idea person and
take it from there.

There are lots of engineers out there that you can hire.  They can make or design
just about anything you could possible dream up.  Coming up with a good idea is
generally the hard part.  Keep in mind that this area tends to be a little more
expensive to develop.  If you are building some sort of electronic widget there are
some considerations that you will have to ask your engineer to check out for added
costs such as UL approval.

What it takes to get started:

Come up with product idea.

Find an local engineer that can produce the electronics portion.

If your product has a case, you will need to find a plastics company to design and mold you a case,
most engineers will have a contact they are use to working with.

Marketing the item is as much work as the design.
