Chumby

A Chumby in the midst of downloading software

The Chumby is a consumer electronics product 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 Chumby was praised as open source hardware: it is designed to be customizable by users.^[1] Wired magazine named Chumby one of its top gadgets for 2008.^[2] Its software is mostly open source, running on Linux.

History

The Chumby premiered on August 25, 2006 at Foo Camp and was released to around 100 alpha release testers at the event.^[3][4]

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.^[5]

In July 2007, a First 50 was released to 50 random applicants, who received the next generation of Chumbys.^[6] 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.^[7] Finally, in February 2008, the commercial release was made public on the Chumby Store.^[8] In May 2008, the price was $179.95^[9] 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 a blue trim. The major difference was the hard plastic casing replacing the soft leather casement. Other changes include a slightly faster processor, only 1 USB port on the rear of the device, and inclusion of FM tuner and physical volume knob. The advantage of the plastic hard case allowed Chumby Industries to offer the Chumby One at a reduced price of $119.95.

Hacks

Hacking the Chumby hardware is encouraged by the manufacturer.^[11] Schematics and other hardware information may be downloaded after the user agrees to the Chumby HDK License.^[12] 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.^[13][14]

Software

A Chumby being held and displaying a Google News story

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 possibly 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.

Multimedia limitations

Although the prototypes did not support video playback,^[15] all current (as of May 2007) retail versions use Flash Lite 3^[16] which allows for Sorenson, FLV, H.264, VP6 and On2 video playback.^[17]
