DIY projects are similar to a rough prototype of any product. True they do not turn out to be sophisticated; but they do offer an amazing learning experience. These projects teach you how to think out of the box, how to use daily use objects to make something without any funding.

The availability of open source hardware and software had allowed engineers, tech geeks and hobbyists to try out projects which required millions of dollars funding beforehand. Now it can be done in a few hundred or less dollars. You can duplicate any product with modifications of your own and that too without spending hefty money on some company’s big product.
