Electronics Hacker, Jeri Ellsworth – 24 hours of Lady Ada Lovelace day #ald10

Pt 2735
500X Jeri Ellsworth Nw Trip
Each hour we are featuring a woman we admire who is currently doing amazing work right in the tech/maker/art/science space. Woman of the hour, Electronics Hacker Jeri Ellsworth!

Jeri Ellsworth is an American entrepreneur and self-taught computer chip designer. She is best known for, in 2004, creating a Commodore 64 emulator within a joystick, called Commodore 30-in-1 Direct to TV. The “computer in a joystick” could run 30 video games from the early 1980s, and was very popular during the 2004 Christmas season, at peak selling over 70,000 units in a single day via the QVC shopping channel. She is a pinball machine aficionado and owns over 60 full-sized pinball arcade games (Lifehacker article here).

Jeri recently put up photos of her “chip fab”. She writes, “It took me 2 years to achieve my dream of making transistors and simple IC’s at home.”


You can tune in to Jeri’s show each week too!


About today:

Ada Lovelace Day is an international day of blogging (videologging, podcasting, comic drawing etc.!) to draw attention to the achievements of women in technology and science. Women’s contributions often go unacknowledged, their innovations seldom mentioned, their faces rarely recognized. We want you to tell the world about these unsung heroines, whatever they do. It doesn’t matter how new or old your blog is, what gender you are, what language you blog in, or what you normally blog about – everyone is invited.

Who was Ada? Ada Lovelace Augusta Ada King, Countess of Lovelace (10 December 1815 – 27 November 1852) was one of the world’s first computer programmers, and one of the first people to see computers as more than just a machine for doing sums. She wrote programs for Charles Babbage’s Analytical Engine, a general-purpose computing machine, despite the fact that it was never built. She also wrote the very first description of a computer and of software.
