In the realm of holiday cheer, where creativity meets innovation, a tale unfolds of Humberto Evans and the Nerd Kits team. Their Christmas project, a harmonious blend of engineering and musical delight, brings to life a xylophone controlled by solenoids and a microcontroller. Prepare to be captivated by the symphony of solenoids and the magic of electronics.
The Solenoids: Electromagnetic Cuffs Unleashed
At the heart of this project lie the solenoids, meticulously crafted as electromagnetic cuffs. Each cuff encases a metal slug, a cylindrical marvel of steel and rare-earth magnets. When current courses through the solenoid’s coil, a magnetic force is unleashed, repelling the magnets on the slug. This sudden repulsion propels the slug upward, striking the xylophone key with a crisp and resonant tone.
The Microcontroller: Orchestrating the Symphony
The mastermind behind this musical masterpiece is a microcontroller, the brains of the operation. This tiny marvel of technology sends digital high signals to trigger MOSFETs, which in turn control the flow of current to the solenoids. With precise timing and coordination, the microcontroller orchestrates the solenoids, transforming electrical signals into a captivating xylophone melody.
A Fusion of Craftsmanship and Electronics
The solenoid bodies, meticulously milled from HDPE (High-Density Polyethylene), provide a sturdy foundation for the electromagnetic coils. These coils, carefully wrapped with magnet wire, generate the magnetic force that animates the metal slugs. The result is a symphony of craftsmanship and electronics, where precision engineering meets the beauty of sound.
Protection and Precision: A Delicate Balance
To ensure the longevity of the solenoids and protect the delicate electronics, a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) and a protection diode are employed. The MOSFET acts as a gatekeeper, controlling the flow of current to the solenoid, while the protection diode safeguards the circuit from voltage spikes and surges. This careful attention to detail ensures the smooth operation and reliability of the xylophone.
