Jeri Ellsworth (born 1974) is an American entrepreneur and autodidact computer chip designer and inventor. Currently the president of Technical Illusions, she became known in 2004 for creating a complete Commodore 64 system on a chip within a joystick, called C64 Direct-to-TV. That "computer in a joystick" could run 30 video games from the early 1980s and was a very popular Christmas gift, at peak selling over 70,000 units in a single day via the QVC shopping channel. In late 2014, Ellsworth moved from Seattle to Mountain View, California with her team.

Biography
Ellsworth was born in Georgia and grew up in the towns of Dallas, Oregon and Yamhill, Oregon, where she was raised by her father, a local Mobil service station owner. As a child, she persuaded her father to let her use a Commodore 64 computer which had been originally purchased for her brother. She taught herself to program by reading the C64's manuals. While at high school, she drove dirt-track race cars with her father, and then began designing new models in his workshop, eventually selling her own custom race cars. This allowed her to drop out of high school to continue the business.
In 1995, at the age of 21, she decided that she wanted to get away from the race car business, and she and a friend started an business selling PCs based around the Intel 486 microprocessor, assembling and selling computers. When she and her partner later had a disagreement, Ellsworth opened a separate business in competition. This new business became a chain of four stores, "Computers Made Easy", selling computer equipment in towns in Oregon. She ran that chain until selling it in 2000, at which point she moved to Walla Walla, Washington and attended Walla Walla College, studying circuit design for about a year. She dropped out due to a "cultural mismatch"; Ellsworth said that questioning professors' answers was frowned upon.
In 2000, Ellsworth attended her first Commodore exposition, where she unveiled a prototype video expansion for the C64. This project later evolved to become the CommodoreOne, a.k.a. the C-One, and C64-DTV, and a video on YouTube "Expo Jeri 1st". Ellsworth then began designing computer circuits that mimicked the behavior of her first computer, the Commodore 64. In 2002, she designed the chip used in the C-One as an enhanced Commodore 64 which could also emulate other home computers of the early 1980s, including the VIC-20 and Sinclair ZX81. She and her fellow developer displayed the C-One at a technology conference, which led to Ellsworth receiving a job offer from Mammoth Toys, which hired her to design the "computer in a chip" for the Commodore-emulating joystick. She began the project in June 2004 and had the project ready to ship by that Christmas. It sold over a half-million units, in the USA, Europe, and elsewhere.
From December 2008 until March 2009, Ellsworth hosted a weekly webcast, Fatman and Circuit Girl, together with George Sanger. On May 30, 2009, Ellsworth demonstrated her Home Chip Lab at Maker Faire Bay Area 2009. Ellsworth was named "MacGyver of the Day" on February 25, 2010 by Lifehacker.
On December 3, 2010 she released information on how to build a TSA "naked" scanner using repurposed satellite antenna parts. Ellsworth has published numerous technical articles online regarding subjects as diverse as homemade semiconductors (2009), homemade electroluminescent (EL) displays (2010), EL phosphor manufacture from common ingredients and ways to make transparent EL backplanes without using expensive indium-tin-oxide coated glass.
Ellsworth was a keynote speaker at the Embedded Systems Conference on May 5, 2011. Ellsworth has made significant contributions to ongoing work on DIY transistors in relation to rapid prototyping as well as thick film fabrication of EL displays using off the shelf chemicals. In early 2012 Ellsworth and several other notable hardware hackers were hired by Valve Corporation to work on gaming hardware. Along with several other Valve employees, Ellsworth was dismissed the following year.
On May 18, 2013, Ellsworth announced that she had developed an augmented reality development system named castAR with fellow ex-Valve engineer Rick Johnson, with the blessing of Valve's Gabe Newell and would be funding it via Kickstarter later in the year. Her start-up company, Technical Illusions, is developing castAR.
Ellsworth later revealed she had been secretly working to make castAR have "true VR and true AR" in addition to the previously announced projected AR capabilities. The castAR Kickstarter, launched on October 14, 2013, reached its goal of $400,000 in 56 hours and finished with $1.05 million, 263% of the original goal.
