C-breeze, a slow dance project

myminifactory

This project draws inspiration from an outstanding instructable at http://www.instructables.com/id/Slow-Dance-a-Fusion-of-Art-and-Magic/?ALLSTEPS. Since many of us are not seasoned woodworkers, we forgo the frame and utilize power LEDs to illuminate objects from beneath, similar to a stage setup. To replicate spring steel strips' flexibility, some feeler gauges (0.3-0.25 mm) are used as makeshift springs. Existing holes simplify the process. Small neodymium magnets attach themselves to the feeler gauges, while ensuring a 0.25mm gauge's distance from the magnet is slightly greater to compensate for its increased flexibility. The coil operates in push-pull mode to achieve maximum amplitude. An 80Hz frequency governs the coil, with LED blink frequencies set just below this value. Adjust the LED controller for optimal results. The first video showcases operation at a lower frequency. Coil dimensions measure 65mm in length and 25mm in diameter, featuring a wire diameter of 0.35mm and an associated resistance of about 8 Ohms. A steel core boasts a 10mm diameter. One photograph demonstrates an LED setup. Over time, these LEDs can become quite hot. For extended use, consider soldering them to the copper side of a PCB using heat-conductive paste, and adding a rear-facing heat sink if necessary. Two o-rings secure objects in place. Since individual control over LEDs and coils requires intricate programming due to the delay function's influence on both components, two microprocessors (ATtiny85) are used to bypass this challenge. A pair of small sketches and an L293D H-bridge IC complete the setup. Feel free to design and create a custom housing for your project.
