Sam Zeloof, 22, made a chip with 1,200 transistors from homemade equipment in his parents' garage. The American wants to make chips more accessible, according to Ars Technica. Zeloof has his sights set on 2,300 transistors, the number used in Intel's 1971 4004 chip which was used in things like calculators. Aware that he lacked the facilities of big production companies, Zeloof turned to books from the 1960s and 1970s for help, according to Ars Technica. This way he could see how companies used to make chips at regular workstations.
