This website has a compilation of over 1000 hacks and the number grows each day as
the Hack a Day tagline reads “Hack a Day serves up fresh hacks each day, every day from
around the Web and a special How-To hack each week.” There are numerous posts linking
to sites where the discussed Arduino project has been originally hosted. Readers can leave
comments and suggestions, or pick on ideas and get on with building their own projects.

Hack n Mod
This website has an index of cool Arduino hacks, projects and modifications (or ‘mods’ that you can
carry out with your Arduino board). The website essentially provides a collection of Arduino projects
at one place and links to blogs/websites of the project host for the details. Hack n Mod also presents
an eclectic list of ‘Top 40 Arduino Projects of the Web’ with projects such as a wall-avoiding robot,
breathalyzer microphone, Web-controlled RC car and Botanicalls—the twittering plant!

The Internet Archive is a 501(c)(3) non-profit that was founded to build an Internet library. Its purposes include offering permanent access for researchers, historians, scholars, people with disabilities, and the general public to historical collections that exist in digital format. Founded in 1996 and located in San Fransisco, the Archive has been receiving data donations from Alexa Internet and others. In late 1999, the organization started to grow to include more well-rounded collections. Now the Internet Archive includes texts,audio, moving images and software as well as archived web pages in our collections, and provides specialized services for adaptive reading and information access for the blind and other persons with disabilities.
