You can find many Arduino-related shops in the world, but there are also a number of suppliers that are good to know about when shopping for the right parts and components.

eBay (World)

One person’s junk is another person’s treasure, and eBay is a great source of tech products that need a new home. Many parts are available through eBay — even quite specific ones. But better than that, you can find other bits of consumer electronics that you can hack to suit your own ends.

Maplin (U.K.)

Skip/Dumpster diving (World)

People are always amazed at the amount of useful stuff that’s thrown away, but they rarely know what’s useful and what’s not. The key is to know what you’re looking for and find out whether you can salvage the parts you need for your project. This may take a bit of Googling because there are so many products and components out there that could be of use to your project.

The motor is one such component that can be extremely expensive if bought new but is used in a variety of consumer electronics that are often discarded. Printers and scanners use relatively complex and expensive stepper motors to work, which can be used again another day. Even the cost of a new printer with several motors can be cheaper than buying motors on their own.
