SAO's Chase Light Inappropriately Employed 555 Code, And Lacked Proper Implementation
In the local scene, oversimplified projects that could've employed more straightforward designs are often taunted with the phrase "Should've used a 555," even if the legendary timer chip wouldn't have been the best fit. However, the underlying message rings true - a Frankenstein's monster of a solution is likely one that requires a rethink. And that's exactly what [Johannes] did with his ingenious chaser light badge, aptly named the Simple Add-On (SAO).
Johannes was inspired by the factory automation machines that move parts between levels, each on steps that move out of phase with each other - much like the marble-raising mechanism in [Wintergatan]'s Marble Machine X. So, instead of opting for any random circuit to turn discrete lights on and off, he went the unconventional route, using two thin plates adorned with notches.
Sandwiched between the 3D-printed casing of the SAO, these plates rest between the badge’s face and light source. A small motor and a series of gears rotate these masks 180° out of phase with each other, thus creating the illusion that the light is moving. It's so convincing that initially, we mistook it for a row of tiny LEDs arrayed around the badge's edge.
Bravo to [Johannes] for this crackerjack mechanism! The SAO was just in time for our European website. If you missed out on the talks, fret not! We've prepped a playlist for your viewing pleasure.
Chaser Light Systems
Chaser light systems, popular in decorative or display applications like badges and signs, create a visual effect where lights appear to move or chase each other. Typically, these systems involve a series of lights controlled to turn on and off in sequence, creating the illusion of movement. If integrated with mechanical components, such as a motor and mechanical plates, the system might involve the motor driving the plates to move in sync with the lighting sequence.
Possible Implementation
- Motor Control: Electronic circuits control the motor to rotate or move mechanical plates synchronously with the lighting sequence.
- Plate Movement: Mechanical plates designed to move in a way that complements the lighting sequence create a dynamic visual effect.
- Synchronization: Precise synchronization between motor movement and the lighting sequence is crucial to achieve the desired effect.
- Power Supply: A suitable power supply, often a DC power source, keeps both the motor and the lighting system running.
- Johannes' ingenious chaser light badge, the Simple Add-On (SAO), utilizes wearables and technology in an unconventional manner by employing two thin plates adorned with notches, powered by a DC source, to create the illusion of moving light by rotating the masks 180° out of phase with each other.
- In the realm of chaser light systems, gadgets and technology intertwine to create visual effects, with mechanisms such as motors moving mechanical components in sync with the lighting sequence, serving as a testament to the innovative fusion of design and engineering.
