Collectors of Steve Jobs memorabilia have a rare opportunity to own a piece of tech history: the Apple co-founder's 8th-grade science fair project. Dated February 29, 1968, the exhibit titled "What Is the Silicon-Controlled Rectifier?" features a 32-inch plywood display with two demonstration circuits, a 10-page report, and Jobs' hand-drawn circuit diagrams. The project also includes a warning note reminding judges to unplug the exhibit after operation, likely due to circuit overheating risks.

Since its creation, the science fair project has remained at the Jobs family home in Los Altos. It is now part of RR Auction's two-part "Steve Jobs & the Computer Revolution: The Apple 50th Anniversary Auction," celebrating Apple's milestone anniversary. The first part of the auction saw the sale of Apple's first-ever company check for $2.4 million.

The science fair project currently has online bids below $3,000, though experts anticipate significant interest. Other notable auction items include a fully functional 1977 Apple-1 computer known as the 'Neumark' system and a development prototype of the original iPod called the 'Stealth iPod,' preserved by former team manager Jim Dumont. These artifacts offer insight into Apple's evolution from its early days to groundbreaking product launches.
