Maker Faire Bay Area 2009
Home Chip Lab

Stage A , Saturday 4:00 PM - 4:30 PM As a curious, creative and misunderstood child with a passion for science Jeri found herself an outcast amongst with her peers. With little appreciation for her talents she turned to high tech pranks, skipping school and taking her own path in life. Against the advice of her family and friends she drops out of school to become a successful race car driver. This was the beginning of a long and twisty path to becoming a self-taught electrical engineer and designing the highly acclaimed Commodore C64 30-in-1 Joystick.

Location: Expo Hall 109

Many have considered making transistors or solar cells at home either too complicated or expensive, but this didn't stop Jeri Ellsworth. She spent 3 years researching and working with mentors who pioneered silicon process in the 70's and devised a way that anyone can do this with safe over the counter chemicals and an inexpensive table top pottery kiln.
