In a touching display of creativity and technical skill, a gifted individual named Agatha has designed a remarkable multimeter as a special present for her mother. This ingenious device, affectionately termed the Mohmmeter, pays homage to its ohmmeter functionality, while also serving as a loving tribute to her mom. The project not only showcases Agatha's technical prowess but also reflects her deep appreciation for her mother through an intricate fusion of technology and heartfelt craftsmanship.

At the heart of the Mohmmeter lies the Raspberry Pi Pico microcontroller, which plays a pivotal role in the device's operation. The microcontroller is responsible for reading the selector knob, which allows users to choose different measurement options. Additionally, it controls relays and illuminates LEDs on the front panel, providing users with clear visual indicators of the meters active range. The Mohmmeter is designed with versatility in mind, offering two primary measurement modes that include two sub-ranges each. This thoughtful setup ensures users can achieve greater precision across a broad spectrum of measurements.

Safety and durability were top priorities in the design process. Agatha implemented circuitry protections to guard against reverse polarity and over-voltage, which significantly enhances the device's longevity. Moreover, considerable effort went into ensuring the Mohmmeter's accuracy; Agatha rigorously tested the device against a calibrated meter, ensuring that the final product not only met aesthetic standards but also performed reliably in practical applications.

The Mohmmeters enclosure is a testament to Agathas artistic vision. Crafted from an array of vibrant wooden panels, each piece is meticulously jointed together, resulting in a stunning visual appeal. To further enhance its charm, stamped brass plates elegantly label the meters various ranges and functions, introducing a delightful steampunk flair that is sure to captivate anyone who sees it. This thoughtful design underscores Agatha's commitment to creating something truly extraordinary as a gift for her mother.

For those inspired by Agatha's creation but looking to cater to a different aesthetic, theres also the option of the Hydameter, which features a sleek, blacked-out design that might better suit a more gothic style. This alternative shows that the spirit of innovation and personalization can extend to various tastes and preferences, ensuring that every gift is as unique as the person receiving it.
