Proposed by professional magician Felice Ling, this system reimagines a standard artist’s kit. Crayons magically appear and vanish at will, and uncolored sketches are instantaneously filled with vibrant color. The routine culminates in a fully realized drawing that can be handed to the audience for close inspection.
Subtractive Manufacturing: Custom-lathed HDPE components to achieve a "slip-fit" tolerance of <0.1mm, ensuring silent telescoping motion.
Kinetic Systems: Integration of industrial-grade retraction mechanisms for high-velocity, repeatable "vanish" effects.
Structural Optimization: An internal 25-degree slanted base designed in CAD to maximize storage (200+ units) within a slim 6mm profile.
This project proposed by professional magician Evan Northrup aims to create a robust, portable stage illusion where a performer appears to levitate while seated on an unassuming bar stool. The goal was to transform a standard piece of furniture into a professional-grade apparatus that is compact enough for car transport but stable and convincing enough for live theatrical venues.
Mechanical Concealment: Engineered a custom 4.6-inch wide stool leg that houses a high-torque linear actuator and dual parallel guide rails, reorienting the motor to the base to maintain a discrete, uniform appearance.
Advanced Mechatronics: Integrated an Arduino Nano with a BTS7960 high-power motor driver and wireless remote triggering, featuring a custom state-machine architecture for automated homing and motion-timeout safety.
High-Load Optimization: Verified through steady-state calculations a 1.2+ Factor of Safety for lifting a 300 lb dynamic load at a consistent speed of 0.5 in/sec.
Acoustic Signature: Utilized vibration-damping mounts to ensure operation does not exceed 40 dB, preserving the theatrical illusion even in silent room conditions.
Commissioned by theatrical consultant Evan Northrup, this project brings the iconic "Beauty and the Beast" rose to life. The rose floats in mid-air within a Victorian display case, dropping its petals one by one in a meticulously choreographed sequence.
Custom Electronics: A DMX-controlled 5V switching PCB designed in KiCad, utilizing an RS-485 transceiver and Arduino slave architecture.
Actuation Array: 12 push-pull solenoids characterized for <50ms latency to ensure perfect timing with theatrical light boards.
Environmental Engineering: A reinforced birch and frosted acrylic enclosure designed to withstand stage vibrations while concealing 100% of internal wiring.
Proposed by magician Felice Ling for high-stakes theatrical environments, this project investigates actively controlled mechanical motion concealed within an everyday object. The goal is a mechanically actuated picture frame capable of transitioning between three distinct images on command, replacing traditional optical trickery with a physical system that can withstand close inspection and physical interaction.
Synchronized Scrolling Systems: Engineered a multi-column scrolling mechanism driven by coordinated stepper motors to prevent skew and ensure perfect image registration across repeated cycles.
Acoustic & Vibration Mitigation: Utilized quiet microstepping drivers and low-noise current control techniques to keep mechanical operation below the threshold of human hearing, ensuring the transition is perceptually invisible.
Mechatronic Integration: Developed a self-contained, battery-powered system with wireless triggering and encoder-based verification for pre-show readiness and high-reliability performance.
Precision Manufacturing: Performed rigorous tolerance stacking analysis on routed and laser-cut components to integrate complex mechanical motion within the slim, confined geometry of a traditional wooden frame.
