The Chumby is a consumer electronics product formerly made by Chumby Industries, Inc. It is an embedded computer which provides Internet and LAN access via a Wi-Fi connection. Through this connection, the Chumby runs various software widgets.
Roughly resembling a small clock radio, it consists of a small touch-screen with a leather and plastic exterior. It uses AC power and turns off if unplugged; a 9 volt battery connector is supplied for backup power. It comes in six colors.
The device is designed to be customizable by users: after agreeing to the Chumby HDK License, users may download schematics and other hardware information. Wired magazine named Chumby one of its top gadgets for 2008. Its software is mostly open source, running on Linux.
As of April, 2012, Chumby Industries, Inc no longer produces hardware. 
Shortly after Foo Camp, Chumby announced a free Chumby offer, where applicants would receive the same alpha-level Chumby as those previously given away. Applicants submitted ideas for software applications or hardware modifications. One of the goals for the free offer was to have Chumbys in the hands of developers who were willing to begin building applications.
In July 2007, a First 50 was released to 50 random applicants, who received the next generation of Chumbys. This was followed, in September, with an Insiders Release. Interested parties could send e-mail to Chumby requesting release information, and were given the opportunity to join in the Insiders Release. Finally, in February 2008, the commercial release was made public on the Chumby Store. In May 2008, the price was $179.95 for any one of three colors, latte, basic black, and pearl. In Japan, Chumby is available through Zyyx, Inc. as www.chumby.jp since October 23, 2008. In Australia, the Chumby is available through ISP Internode.
In November 2009 the Chumby One was released: a similar, all-plastic version of the original, only available in white with blue trim. The major difference was the hard plastic case replacing the soft leather. Other changes include a slightly faster processor, only one USB port on the rear of the device, and inclusion of an FM tuner and physical volume knob. The hard plastic case allowed Chumby Industries to offer the Chumby One at a reduced price of $119.95.
On 20 February 2013, Chumby shut down its servers leaving users with a simple clock that shows time, calendar, and date. A brief message appears on the Chumby website explaining the suspension of service.

Hacking the Chumby hardware is encouraged by the manufacturer. Schematics and other hardware information may be downloaded after the user agrees to the Chumby HDK License. For example, users on the Chumby Forums have experimented with and documented some battery hacks, allowing the Chumby to be operated without AC power for short periods of time.
There also exists a Chumby Hacker Board that mostly resembles a Chumby One motherboard. There are some differences to hardware connectivity. Chumby Industries doesn't officially support the board. 
Chumby units run a modified Linux kernel. The software originally installed on the device is designed to play a set of user-customizable widgets, small Adobe Flash animations that deliver real-time information. This is possible because an embedded version of Adobe Flash Player is installed. The animations have the ability to control and interact with the low-level hardware, thereby enabling functionality such as smart alarm clocks that bring the hardware out of sleep, a web based picture viewer, a web based camera, online RSS feeds, and physical user interface features such as gesture recognition through squeezing the soft housing.
The software for the Chumby automatically updates when something new becomes available. The updates come from the free access to the Chumby network, and a modified BitTorrent client is used to upgrade the open-source portions of its firmware.
