TinkerKit Website Offline
Future support for the TinkerKit electronics range is in doubt, after their website (tinkerkit.com) went offline unexpectedly in mid-2014. The issue has been discussed online, in sources including the Arduino forum and Reddit.com.
Alternative TinkerKit Resources
This sudden disappearance will come as a big blow to the many TinkerKit enthusiasts, leaving them without a major source of support. However, archived 'snapshot' copies of the TinkerKit website have been preserved by the Internet Achive's WaybackMachine.
Example sketches may of course be accessed from the Arduino IDE with the TinkerKit library installed (File > Examples > TinkerKit), and the libraries themselves remain available from GitHub.
