In this episode, Ruby takes on the challenge of retrofitting a 1958 Bally Bingo machine, affectionately renamed Ms. Creaky for brevity and the loud noises it makes during gameplay. Miss Creaky belongs to the era of electromechanical wonders, boasting an intricate network of switches, relays, and a labyrinth of wires that surpasses any electronic project Ruby has encountered.

Despite warnings about the complexity of electromechanical pinball machines, Ruby dives in with a plan. Step one involves deciphering Ms. Creaky's schematics through online forums and gaming communities. In step two, Ruby identifies components for modernization, considering replacements like LEDs for light bulbs and exploring options for a solid-state board. Steps four through six are dedicated to the inevitable process of troubleshooting, a task that might involve a few tears.
As Ruby embarks on the physical dissection of Ms. Creaky, the upper cabinet, lower cabinet, and playfield each get meticulous attention. Cleaning, inspecting, and testing switches become routine. Challenges arise, including a broken contact in the ball return mechanism and a nerve-wracking moment when a previously functioning part fails to perform after reassembly.
Ruby's journey gives her an understanding of Ms. Creaky's unique shutter motor and the intricacies of electromechanical design. The episode captures the highs and lows of the restoration process, including the elation of overcoming unexpected hurdles and the frustration of discovering new issues.
As the project progresses, Ruby contemplates modernizing Ms. Creaky by replacing components with more contemporary alternatives, including considerations for motors, stepper motor drivers, Arduino integration, and the potential use of LEDs. However, the sentimental value attached to Ms. Creaky's historical components ultimately leads Ruby to reconsider a full modernization.
In a surprising turn, Ruby decides against tearing out Ms. Creaky's original components and embracing the worn details as a testament to her rich history. The post ends with a reflection on the learning experience, acknowledging the importance of reliability and repairability in engineering.
Despite the challenges and the deviation from the initial plan, Ruby expresses love and appreciation for Ms. Creaky, leaving us with a finished, slightly cleaner, and fully functional pinball machine! Have you had a similar journey with vintage electronics?
