In August, Intel revealed details about its plan to build a $100B factory on US soil. In the same month, 22-year-old Sam Zeloof announced his own semiconductor milestone. Unlike the tech giant, it was achieved alone in his family’s New Jersey garage. https://wired.trib.al/NOlbqrD 1/9
Computer chip fabrication is sometimes described as the world’s most difficult and precise manufacturing process. With a collection of salvaged and homemade equipment, Zeloof produced a chip with 1,200 transistors.

“Maybe it’s overconfidence, but I have a mentality that another human figured it out, so I can too, even if maybe it takes me longer,” he says. 3/9
Zeloof hopes to match the scale of Intel’s breakthrough 4004 chip from 1971, the first commercial microprocessor, which had 2,300 transistors and was used in calculators and other business machines. 4/9
His chips lag Intel’s by technological eons, but Zeloof argues only half-jokingly that he’s making faster progress than the semiconductor industry did in its early days. His second chip has 200 times as many transistors as his first, a growth rate outpacing Moore’s law. 5/9
While garage-built chips aren’t about to power your PlayStation, Zeloof is convinced that society would benefit from chipmaking being more accessible to inventors without multimillion-dollar budgets. : Sam Kang 6/9pic.twitter.com/0nRTgZ7UQV
His project has earned a dedicated Twitter following and millions of YouTube views, as well as some handy tips from veterans of the 1970s semiconductor industry. 7/9
Now, he’s thinking about the functions he could build. His creations show what’s possible for small-scale silicon tinkerers. Discover how it all began. https://wired.trib.al/NOlbqrD 8/9
