What differentiates a commercial product from a hobbyist project?

<< < (5/7) > >>

Tomorokoshi:
Expect $100,000 for approvals and testing, along with 4 layers of management for a commercial product.

NiHaoMike:
The biggest difference is that companies will do whatever they can get away with to cut the last cent off the production cost, while hobbyists will gladly pay a few more dollars or more on a serious project if it means getting better performance or an easier time getting it to work.

Depends on whether or not the product deals with high voltages and/or RF, and if it does, whether it uses off the shelf or custom devices to interact with those.

I know of the opposite: companies (e.g. HP) prepared to spend a lot of money to buy equipment that will help get the product out of the door 3 months earlier. Sometimes hitting a certain market window is more profitable over the product's lifetime.

The enclosure. It takes 2 seconds to tell if something is made for sale vs for fun.
Us hobbyists are not able to think in 3 dimensions to make mechanically sensible things. As long as 2D board is finished the project is over.

The extra components other than fuses at efor example safety circuits that make sure the thing doesn't do any harm when software goes tits up. Because if the software failure may cause property or health damage and you product falls under 60335 or 60730 group of standards you need to go for class B software. And external audit for this costs shitload of money and some really massive documentation.

You need to do safety FMEA and make sure that the product is safe under single fault conditions. That's why you will see stuff like 2 relays in series for example (makes sure that even if one of them gets welded the other one opens and brake the circuit).There are integrated safety relays that basically have 2 coils and 2 sets of contacts.

Some extra components are for EMI compliance.
