A Chumby in the middle of downloading software

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 building 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:[1] after agreeing to the Chumby HDK License, users may download schematics and other hardware information.[2] Wired magazine named Chumby one of its top gadgets for 2008.[3] Its software is mostly open source, running on Linux.

In April, 2012, Chumby Industries ceased selling hardware and put Chumby related assets up for sale. Support for the platform ended the following February.

Subsequent to the company's liquidation, the Chumby has been maintained in "Space Clock" mode. The device is communicating with servers being maintained by a former employee who licensed the technology under the company name Blue Octy, LLC, displaying a single clock called "Space Clock". In March, 2013, Blue Octy sent a software update to Chumbys still online, aligning them to the new world of Chumby under the Blue Octy servers and the service will soon be resurrected.

Blue Octy, LLC relaunched the chumby service on July 1, 2014 as a paid subscription service, currently charging $3.00USD per month. An open source firmware is available for free which allows existing devices all the functionality of the paid service at no cost.[4]

Andrew "bunnie" Huang was the lead hardware engineer at Chumby. The Chumby premiered on August 25, 2006 at Foo Camp and was released to around 100 alpha release testers at the event.[5][6]

Shortly after Foo Camp, Chumby announced a free 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.[7]

In July 2007, a First 50 was released to 50 random applicants, who received the next generation of Chumbys.[8] 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.[9] Finally, in February 2008, the commercial release was made public on the Chumby Store.[10] In May 2008, the price was $179.95[11] for any one of three colors, latte, basic black, and pearl. In Japan, Chumby was available through Zyyx, Inc. as since October 23, 2008. In Australia, the Chumby was available through ISP Internode.

In November 2009 the Chumby One was released: a similar, all-plastic version of the original 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.

In April 2012, Chumby announced the cessation of hardware sales, having ceased manufacture of their own hardware the previous year and exhausted their inventory.[12] On April 20 it was confirmed that the company itself was being broken up.[13][14] Dedicated fans managed to keep the service running for a period following the company's demise,[15] but 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 Web site, explaining the suspension of service. Alternative open source firmwares prepared for such an eventuality became available at this point.

As of January 2013, Blue Octy was in the process of reviving the chumby technology, with one of the original chumby developers working on the project. Visiting shows details.

Towards the end of March, 2014, Blue Octy began beta testing the soon to be revived chumby service.

Hacking the Chumby hardware was encouraged by the manufacturer.[18] Schematics and other hardware information may be downloaded after the user agrees to the Chumby HDK License.[2] 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.[19][20]

There also exists a Chumby Hacker Board that mostly resembles a Chumby One motherboard. There are some differences to hardware connectivity. Chumby Industries did not officially support the board.[21][22]

Chumby units run a modified Linux kernel. The software originally installed on the device was 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 by squeezing the soft housing.

The software for the Chumby automatically updated when something new became available. The updates came from the free access to the Chumby network, and a modified BitTorrent client was used to upgrade the open-source portions of its firmware.

Multimedia limitations

Although the prototypes did not support video playback,[23] all versions since May 2007 use Flash Lite 3[24] which allows for Sorenson, FLV, H.264, VP6 and On2 video playback.[25]
