Roboticist-Turned-Teacher Built a Life-Size Replica of Eniac

A roboticist-turned-teacher built a life-size working replica of ENIAC using only 26 points and 6 comments on Hacker News, yet this feat demonstrates extraordinary dedication to computing history. The replica contains 17,468 vacuum tubes and consumes 150 kilowatts of power, faithfully reproducing the original's 1945 specifications. While smaller in online engagement than the #7 Mac Studio shortage, this project offers an unrivaled interactive educational tool, allowing students to run actual ENIAC programs without the $487,000 cost of maintaining a real unit.
